Digital battery

Battery frost and key technologies:

 

1. The main raw materials of design calculations, selection and matching

2. Gel batteries special plate design, formulation and manufacturing process

3. Colloidal formulation and preparation, the dispersion SiO2

4. Early loading or filling operation

5. New gel batteries for added power technology

 

1. The main raw materials, design calculations, selection and matching

 

Gel batteries, the need to report the positive and negative electrode capacity, the thickness of the partition size, plastic shell the size of support, including IBM ThinkPad T60 battery capacity and the plastic shell size of single cell the relationship between the parameters corresponding to a series of reasonable arrangement. In general, single-cell battery should be able to guarantee an effective space filling of acid amounted to 12-15 ml / AH to protect the battery in the amount of the effect of the adjustment of acid-containing gel.

 

A common problem is the use of sealed AGM batteries the standard plastic shell to act as a shell plastic gel battery, which is often caused by insufficient capacity or the battery open circuit faults in voltage and other issues. Another problem more common in domestic PE separators such as the use of private partitions instead of gel batteries, or use a sleeve of fiberglass, silk short sleeves instead of polyester gel battery box Dedicated partitions, which are most seriously affected product, life makes life / cost, but not worth the candle.

 

Users demands long battery life expectancy colloid required in the design and equipment selection, when it should be more stringent than the conventional design sealed Dell Latitude D520 battery, seal the pole to the growth and expansion of plate boundaries, etc., required in the structure must be considered and there should be corresponding measures, such as strength and size of pads and linings using a special pole structure, and enough interior space.

 

It is worth noting is how to prevent the assembly process in the break and short circuit group to protect the qualification rate of finished product.

 

2. Colloid plate special battery design, formulation and manufacturing process

 

Private plate gel batteries in particular, positive plate, and plate sealed classic comparison of the battery must be adapted to gel batteries (electrolyte) Special Requirements:

 

A, the requirements of colloid infusion: making the electrolyte in the hp F2024B battery is full all the corners;

B, to eliminate the polarization resistance increases due to the uneven increase in effect, require grid support structure design reasonable, hob, drying process reasonable and practicable;

C, regardless of recycling or floating charge to use, require long life, there is no thermal runaway phenomenon;

D colloidal form a network structure on the plates and separators and opening requirements of the porosity;

E, moreover, the actual conversion time of the battery in question.

 

3. Formulation of colloids and preparation process, SiO2 dispersion

 

A, first of all, is a gel battery needs to know the problems that the sony VGP-BPS2A battery needs to determine colloidal properties.

 

Council of the battery positive and negative active material in the electrolyte, after infiltrating the structure, you can get some inspiration.

 

Contrary to watch active substances of the structure and composition changes in the electrolyte after injection, the active material and electrolyte combination of regional, living matter was crystal - colloids (crystal structure of the glue) , sulfuric acid and water can freely enter the active substance through the diffusion of network structure of the territory, but the plastic changes of crystal structure depends largely on living material (lead dioxide or metal ) and lead sulfate (sulphate) conversion, while the sulfuric acid and water, and generate little to do with the reduction or can not be because the sulfuric acid or water to increase and decrease in moisture or frost. Therefore, life can always keep the stability of the structure. Thus, it can analogy to say that the sulfuric acid and water in the role of colloids: In the additive in the plastic front, followed by injection in the plastic, but should not be the structure of colloidal constructions.

 

Previous studies, often the chemical transformation of silica hydration —- begin to draw on the reversible reaction of water glass to understand the mechanism of the colloidal structure, and it is very easy to stick on the glass water and other resources, and even the two Silica gel hydration is a key step.

 

In fact, if the set colloidal structure of sulfuric acid and water are the structural components, toshiba PA3285U-2BRS battery charge-discharge process in the corresponding chemical reaction caused by sulfuric acid and changes in the composition of water in the original colloidal structure will inevitably lead to fragmentation, collapse and reorganization, the correspondent must gel hydration and shrinkage. It is difficult to say that the battery life to meet the needs of a stable structure. Therefore, this myth should not be allowed to continue.

 

After that, we had an aging test (after festivals worldwide after the battery charge-discharge cycles, the crack formation) and gel batteries to overcharge and over discharge to verify this conclusion, a mainstream (0.2C to 0.3c) conducted on a full charge of battery power (1.5C to 3.0C), or excessive discharge and closing terminal battery voltage to 0V (discharge volume reached 1.2C to 1.5C, and even more). These experiences, we can see (police) for gel batteries warm, but we see no moisture to freeze.

 

B, the gel formulation and preparation, the more critical is the dispersion of silica. Not studied ultra-fine powder or knowledge, it is difficult to understand the dispersion of the dispersion of silica rigorous requirements. The ultra-fine powder technology in the industry of household batteries are not very partial knowledge of point to study the dispersion of silica dispersed in water is almost pitiful papers, research focussed mainly in paints, etc. Hang Dang.

 

C on silica thickening and thixotropy awareness, in particular, recognize that the thickening of the silica and thixotropy are not inalienable, a process of inappropriate preparation could affect the silica thickening and thixotropy. Right filling process of plastic production, the thixotropic gel is very important, but the life of the apple iBook G4 14 inch battery in the finished product, the colloidal thixotropic Zexu eradicated.

 

D, training battery, and the plate pairs of colloidal have different needs, a corresponding change in the colloidal components.

 

4. To start charging or filling operation

 

Many people are beginning to charge or recharge the battery capacity as a simple process to adjust and active substances in the process, prefer to be adjusted according to their understanding of recharge processes. In fact, the process of loading the gel battery is just a hammer 100 to 1000 the training process, each side in the process of loading and unloading steps is mutually reinforcing.

 

Enjoy the cooking equipment plate, the initial charge of battery for a complete charging process must address the following questions:

 

A plate active material fully translated to protect the battery capacity;

B, plate active material of structural adjustment in order to form a relatively homogeneous and colloidal;

C, reaching the original glue and sulfuric acid, water exchange, the formation of uniform colloidal structure, fully utilize and improve colloidal thickening, reduce the thixotropic gel to form a stable colloidal structure;

D set the Dell GD761 battery voltage and capacity, to adjust the consistency of the battery (capacity, resistance, voltage, etc. coherence).

E, charging additional water loss and water temperature control, and so on.

 

5. The new gel batteries add power technology

 

The new gel batteries, the aging treatment are not a new battery, because not yet formed cracks. Therefore, in the charging of fees to certain requirements.

 

Unreasonable electrical process may be more intense mixing effect, undermine the stability of the colloidal structure, hydration, once produced, it undermines the performance of colloidal thickening. After charging, it is easy to create a localized or overall hydration, this is a very serious damage to the gel, and it will significantly reduce the lifespan of the battery.

 

Stockpiles new gel properly shelved is also aging, can form cracks.

 

How the new batteries with gel methods are most rapid economic and environmentally sound treatment in the aging of the battery that is worth seeing.

As the core of electric vehicles, power battery applications with the particularity and complexity. To say, have the last hundred years, not the power battery development is bad, but the oil industry and the automotive industry is too large outstanding technological progress. Power Battery experience in the manufacture of batteries, batteries, battery modules, batteries, four-level links, the whole power system, Laptop battery technology has repeatedly stressed the concept of necessity is: consistency, standardization steps. From a technical achievement levels, ranging from small battery-battery technology upgrade to power, not simply “addition” can be easily reached. Power Battery performance factors (power density, energy density, durability, safety, cost) rings linked, high-power and high energy prices on the development and manufacture of hard to take into account a long time a serious impact on the work of the high-power battery, High-Power exothermic phenomenon of the work of the security of the test battery, energy efficiency must be sacrificed in order to obtain a longer life, high energy density and safety risks. This is technically difficult to obtain a full range of meeting, but only to find a balance, but also with the vehicle fuel system that is the biggest challenge for technology comparison. Route choice in technology, nickel metal hydride batteries, native defects (self-discharge, specific energy is small), it was replaced by lithium batteries, only a matter of time. However, the lithium battery line, a series of disputes can the electrode materials, different systems of lithium manganese oxide have, lithium iron phosphate, nickel-and cobalt-manganese ternary and other technical line. Of the lithium iron phosphate battery technology A123Systems lost Chevrolet tender incidents, automobile manufacturers program the freedom of choice of batteries, for a variety of technical path to wait. We believe that automobile manufacturers’ lithium IBM ThinkPad R40 battery technology is not just over the line, more concerned about the patent dispute, suppliers, manufacturing capabilities and financial strength, etc., it is systemic issues. Main lithium-ion battery makers are still the most commonly used lithium manganese oxide system, Ni-Co-Mn and other technical way, as we believe that given the uncertainty in technological progress, lithium battery technology fronts will be difficult in the 2-3 years will have a clear statement does not preclude the international community, the first benefit of industrialization is the more mature xHEV lithium manganese, nickel, cobalt and other battery-Mn line. Battery is still in the global industrial R & D phase is uncertain, the domestic industry structure and outlook, it is certain that China is in the technical research and development of battery power, battery and vehicle research and development and improve the docking Power battery industry support intensity.

 

The direction of the battery lithium ion battery that can be in Japan and the United States of lithium-manganese-lithium-divided iron. Lithium manganese battery refers to the lithium manganese oxide cathode materials LiMn2O4 in propulsion. Lithium-iron Dell Latitude D510 battery refers to the lithium iron phosphate as cathode material LiFePO4 Power Battery. Us for a comparison:

 

Security

 

Lithium-ion battery charging and discharging process of lithium-ion embedding / de-embedding process. When the crystal structure in the process stability, not change is the battery of security to be high. Otherwise, is that is small, such as the layered structure of the cobalt oxide lithium battery charging voltage rises under the circumstances, the cathode material of lithium ion in the other continued to de-embedded to swim with the cathode, anode material at a time when the filled in the position to the location of the lithium-ion site was, lithium-ion only in the form of metal precipitation on the surface. Such problems arise. On the one hand, the surface of lithium metal deposition is very simple, formed a branch of the form, poly-lithium dendrites, the membrane-penetrating, leading to positive and negative direct short circuit, the other hand, lithium metal is very lively, is a direct response to the electrolyte and heat have, at the same time, the backup lithium is very low, although it is not the surface of the lithium metal dendrite membrane-penetrating, as long as the temperature is slightly higher, as the hp Pavilion DV1000 battery by heating by the discharge of lithium is -melt metal, so that positive and negative short-circuit, causing accidents. There is a high temperature and depth of the charge-discharge process, the cobalt and oxygen bond can be broken to release oxygen and produce an explosion. Lithium cobalt oxide battery temperature of only 150 degrees, the lowest of the three cathode materials. Therefore, the security of the largest lithium cobalt oxide is a short-board batteries.

 

Lithium manganese spinel crystal battery, lithium-ion embedding / de-embedding process is stable, secure high. The oxidation temperature of 250 degrees of lithium cobalt oxide batteries than a full 100 degrees higher. However, in the depths of the charging and discharging the material lattice Kawasaki (susceptible to changes, especially at the higher temperature), and manganese-oxygen bond can be broken to produce and release oxygen in an explosion. There is also a high temperature lithium-manganese oxide crystals slowly dissolved in the electrolyte problems. Lithium manganese battery and must therefore take a variety of security measures to improve security.

 

Lithium iron phosphate sony VGP-BPS2A battery is currently the safest battery. Its unique crystal structure of olivine in the phosphate-base for the entire material has a stabilizing effect, makes the material itself has thermal stability and good cycling performance. This is one of the key in the lithium iron phosphate lithium-ion differs from LiCoO2 cathode material of lithium cobalt oxide and lithium manganese LiMn2O4 with a one-dimensional direction of their mobility, the charge-discharge process can undo and be accompanied by extrusion, and move a central metallic iron oxidation and reduction. In addition, the phosphorus-oxygen bond and strong, so lithium batteries short-circuited, it is not because of the short circuit and produce an explosion. The oxidation temperature is higher than 400 degrees, can be placed on the fire. Therefore, increasing the cathode material lithium cobalt oxide and manganese-lithium battery for the safety had to take on a variety of means, while the cathode material lithium iron phosphate is a naturally have security.

 

Economy

 

How much do the cobalt to the high price of lithium cobalt oxide material. Manganese is rich in natural resources are cheap, while lighter lithium manganese preparation, manganese-lithium batteries and low cost. Phosphorus and iron-rich cheap, but difficult to lithium iron phosphate preparation for its low rate of sintering of the finished product, so that the material lithium iron phosphate battery costs. To reduce the cost of lithium iron phosphate a variety of methods, such as increased production, improved technology and so on.

 

High Capacity

 

Including the electrical power and voltage. Theory of the highest capacity in the lithium-cobalt, manganese and lithium the lowest. However, in order to assess the safety, the actual performance of lithium cobalt oxide of a compromise, only about half the theoretical capacity. Thing like this would, if you have to increase generating capacity to sacrifice safety. Security, high theoretical lithium manganese oxide with a low capacity means that there is not much scope for the development of electric power and up to 148mAh / g VGP-BPS10 with greater safety in comparison, lithium iron phosphate, it was made in the laboratory 160 mAh / g capacity of the actual performance. Of course, the operating voltage of lithium iron phosphate as low as 3.3. But it has a very flat voltage platform, which means it is more stable and efficient discharge properties.

 

Fast Charge

 

Speed of charge from the conductive material decision. There is no doubt the worst of lithium iron phosphate. This is because the lithium iron phosphate lithium-ion extrusion, reducing the volume of the grid, from which a total FeO6 octahedron corners, because they can not be separated by oxygen atoms to form a permanent FeO6 network structure, whereby the electronic conductivity. On the other side of the crystal in the oxygen atom near the main road of tightly packed six-party agreement, so that the lithium-ion offers only limited access, allowing lithium ions in the structure at room temperature in a very small migration rates. But that does not mean that lithium manganese oxide can be easily achieved fast loading. Because of its crystal structure of lithium iron phosphate is not stable, high current fast charge may mean that the bars come saki changes, the key of the manganese and oxygen can be broken, which means an explosion. By pair-doped lithium iron phosphate, for example, by adding carbon, cobalt and the like will be the conductivity is greatly increased. BYD experiments reported that his 10 minutes to the apple M8403 battery to 80% are filled.

1, high-profit event

 

U.S. First Solar’s gross margins above 50%, but such a high gross margin because the company has a core of cadmium telluride thin film technology and its equipment are mostly self-designed, proprietary technology, so their cost than most solar companies is much lower. From the breakdown of costs can be verified that, although First Solar equipment depreciation for 5 years, compared with the other producers have AMAT Applied Materials, Inc. 7 years shorter, but still higher than the depreciation expense of the unity of the amorphous silicon plant AMAT more than 20% lower than the AMAT of the laminated product is 40% or more. First Solar thin-film producers all over the world, a good benchmark, but it’s amazing the goal is not easily available, and the general activities des

 

2, technical risk concerns

 

Due to rapid technological progress, the average price of polysilicon components from the current level of $ 4 / W by 2012, two U.S. dollars / W; thin-film batteries from the current $ 2 / W to $ 1 / W, the thin-film makes solar production capacity could reach 20% of the total solar energy, is now only 7.6%. Thin-film solar sony VGP-BPS2A battery technology must be improved, for example, need to improve the existing microcrystalline silicon coating because the thickness of the microcrystalline silicon solar impact performance. Thin-film solar batteries to do is thin, the conversion rate to improve a significant reduction in thickness to reduce production costs and other metrics. Most of the province of silicon thin-film battery is using a special process that continued gas with silicon deposited on glass carriers can form a layer of paved with nano-scale particles of silicon film as a piece of glass, with an area of up to 1 square meter, or even a few square meters. The thin-film solar batteries in the same size on the weaker power generation capacity than conventional batteries, photoelectric efficiency of only about 6%. Chinese Academy of Sciences Guangzhou Institute of Energy, according to recent forecasts by the year 2015 this number will increase due to technical advances by 12% to 16%. The world’s most advanced ion-beam deposition of nano-crystalline silicon thin-film technology, China is still empty. Crystalline silicon batteries with very different production technology is widely in manufacturing thin-film battery, like the semiconductor industry, such as vacuum coating technology, key technology have used this level of mastery and advanced directly to the volume of products affected income, indirect impact on the profitability of the company. Thin-film battery industry is a technological innovation on the rapid development of industry is based has been built is to explore one of the best process route too, so the need for continued improvement from the technology point of view thin-film sony VGP-BPS2 battery factory, manufacturers of crystalline silicon solar batteries are producing more need for a strong R & D and technical team. From a technical originality, digest and absorb and re-raise three are usually standards, Chinese companies are only in the most important independent intellectual property rights of long term in a weak position. If you can not catch up, then the thin-film solar batteries has continued to migrate to the “Introduction, backwards, then the introduction of” passive follow the trend of the old road, not in a position to the chain from production to sales of high End-to-fill.

 

3, equipment and raw materials short board

 

Thin-film battery technology development is shorter forms, no common technology and common equipment, the latest large-format thin-film VGP-BPS9/S battery devices offers a turnkey project is primarily the United States, Applied Materials (AMAT), Switzerland, Oerlikon and Japan’s ULVAC 3rd Equipment depreciation is one of the major costs of thin-film batteries, according to the current stock market listing, with the capacity of the battery production line of thin-film silicon prices are 6-10 times, including glass (glass and other conductive glass), EVA, Target and Gas and other important raw material supply, the current international giants are monopolies, high prices and no supply. ITO thin-film batteries require a higher current strength of weak domestic manufacturers, the market especially from Japan, NSG and the U.S. AFG partition. With the outbreak of the domestic production of thin-film batteries to supply most likely the result of the main raw material. Target current domestic supply, which is dominated by large international companies, Heraeus, Germany is the world’s largest supplier on the domestic market share of more than 6 in. Moreover, there is no domestic production of silane, but mainly large international companies with limited expansion opportunities as demand for LCD and other high silane is coupled partial delivery is still in short supply, prices continue to rise to maintain a high level does not exclude the possibility silicon thin films face Queliao risk. In addition, the thin-film cadmium telluride (CdTe) materials, there are still concerns about the toxicity, environmental protection and recovery mechanisms, tellurium supply mechanism hidden dangers, copper-indium-selenium (CTS CIGS) materials, it is the question of indium prices.

 

4, the market risk

 

Everything that is divided into two halves, and look at problems of the market, there must be an objective analysis of dialectical materialism. The great development of the photovoltaic industry, leading to rising prices of key raw material silicon, and finally forced to alternatives to the downstream business, believe it promoted the rapid development of thin-film technology on a very large number of companies find that they have a Starfall, crystalline silicon solar technology found pregnancy dive with a great breakthrough in the pricing on the eve of a sharp. This result is still at the level of the small thin-film Dell Inspiron 8500 battery market and the strong momentum of development will be the impact of changes in market investors form must be fully understood, otherwise errors can occur.

 

5, risks of investing in

 

Currently, Chinese companies have much in the introduction of foreign monopoly, invested thin film solar battery production lines. Three giants of the world, one of the United States, Applied Materials, Inc. amorphous silicon thin film solar modules to produce a series of automatic production line, for instance, to project a total investment of 14 billion yuan, annual production of amorphous silicon thin film solar batteries 500MW, with an annual turnover of 20 billion yuan. Investment intensity per megawatt of production capacity by 2800 or 28 million yuan RMB per watt, a turnover of 40 million yuan to invest grid / MW, or 40 yuan / W. This easy-to tens of billions of investment risk should be carefully examined. Switzerland and Europe Likang automatic production line of thin-film hp PP2182L battery prices of imports of 100 million yuan dollar, combined 700 million yuan. In addition, the production process is environmental issues will consume a large amount of investment in environmental protection department or face opposition.

 

6, financial difficulties

 

Solar PV industry is a money-burning industries, the financing capability of a large company test. But the most dangerous place, but also risky places, is from a philosophical standpoint, the greater the risk, the greater the chances. In other words, there is no opportunity without risk. The wind is now that my votes. With minimal investment to earn the greatest profit, is the eternal view venture capitalists, but also the strategic goal of the philosopher, the two differ only pure venture capitalists will benefit as a goal. Investors on the financing side of the evaluation criteria are mainly two first the profitability of enterprises, followed by the scale. In addition, enterprise system, corporate culture, team composition, executives and others have an assessment. Standing at a higher level view of these questions, we will have time to go see the industry that has little relationship, because the key to see the VGP-BPS10 results. First come, the current environment, then there are other problems can not be generalized.

 

Our answers:

 

1. R & D and commercialization of solar PV companies should also focus on understanding the two. Accurate select the entry point to participate partially in control of the situation with the strategy, both in accordance with national conditions, also in line with the best economic option because the lowest price to produce the best results are always the best choice for investment. “Power wins very brave man to win power disparity wise man.” Achieve control of the situation, do so by local targets, the need for more intelligence to this, because it requires a global vision of a comprehensive strategy, intelligence and strategic courage. People who can not fearful strategy for winning the top spot because it is often the most dangerous, but also the balance of power in force. Big bet on solar PV by the “technology innovation and lower costs” that two keys so that the cost of solar power for the next generation of 0.5 yuan per kWh on the price and VGP-BPS9/B thermal energy equivalent to a strong competitive advantage to connect on the market to the premise of the initiative to regulate the use of large scale, when promoting the market demand burst like a blow-out type, solar batteries on board from the current use of additional alternative energy peak.

 

2. Although the same time, faced with a shortage of materials, technology development, leading talent and its own challenges, such as intellectual property rights very short, but we are committed to their own multi-level research and development team, construct addition, it should with Applied Materials to work as the United States, Japan, ULVAC, Switzerland, Oerlikon thin-film battery technology world, such as monopoly giants technology alliance, which is a good strategic decision.

 

3. Japan’s Sharp Corporation developed a prototype solar batteries on gallium arsenide ingots, has its photoelectric conversion rate reached 25-28.5%, according to the story of Sharp, an energy efficiency approaching 30% can have a prototype product, when the actual efficiency of production is very up to 20%. Who is the first to master the advanced technology, who reflects the lead in industrialization, the first to the photovoltaic industry, “high growth, high investment, high output” properties.

 

4. Production of photovoltaic power in China today is not simply the application of power, short-term needs the support of the international market, but the long-term strategic perspective, the domestic market is a strong resource can not be ignored. Together with the opening of the domestic solar PV market approaching footsteps, “staking their claims,” floating on the operation of the tactical turn table. Need as quickly as possible sunshine intensity of the former government signed a joint construction of three solar power plant demonstration project cooperation agreements for the construction and application of solar energy, local governments, or if the BATBL50L6 technologies and products ready to promote the market have been divided since a long time.

Introduction 1 battery is a UPS system is an important component of its direct impact on the bottom of the reliability of the whole UPS system. No matter how UPS designed for advanced features complete how, once the Laptop battery failure, even the best UPS is also unable to provide an uninterrupted power supply. Do not use inferior quality and cheap due to covet lead acid batteries, it will affect the reliability of the entire UPS system, and will therefore result in greater losses. Batteries entire UPS system mean time between failure (MTBF) over the game. If the use and proper maintenance, will be able to extend its life, instead of his life will be shortened. Therefore, we must understand the basic principles and considerations of the use of the battery.

   

Two general types of lead-acid batteries can be divided into lead acid batteries, maintenance free lead-acid batteries and nickel-cadmium batteries, taking into account the load conditions, the use of environment, life and cost and other factors, typically chosen UPS VRLA maintenance free batteries. Its main feature is the load generated when the cathode side oxygen by chemical reaction in the negative to reduce water use life float specified without adding water to maintain, so called maintenance free lead-acid batteries. Maintenance free battery is only when compared to the normal process eliminates the need to add water or distilled water, adjust the surface of the electrolyte of the work is not relieved all maintenance work. Instead, to achieve the UPS uninterruptible power supply, we must be more careful in safeguarding and maintaining good lead-acid maintenance-free batteries.

   

Three main factors affect the life and warn us about the following important factors affecting the life of the hp Pavilion DV1000 battery and use the process should pay attention to the questions:

   

⑴ temperature greater impact on the battery. The ambient temperature is too high, the battery will overload produces gas, the temperature is too low, the battery will be pretty cool, it will affect battery life. Therefore, the general provisions of the ambient temperature around 25 ℃, UPS is also float temperature setting voltage. Practical applications, the battery is generally 5 ℃ ~ 35 ℃ in the office, below or above 5 ℃ to 35 ℃ will greatly reduce battery capacity and shorten battery life.

   

⑵ deep discharge of battery life also has a great influence. More depth of battery discharge, less the number of recycling activities, and should therefore avoid the use of depth of discharge. Although the UPS has a battery low protection potential, the general single-cell, when discharged to 10.5 V or more, UPS will automatically be closed. However, if the UPS is lightly loaded or discharge any discharge load may cause the depth of battery discharge.

   

⑶ batteries in the storage, transportation, installation, following the loss of part of the self-discharge capacity. Therefore, after installation before commissioning should be based on the open circuit voltage of the toshiba PA3191U-3BRS battery to determine the remaining capacity of the battery, then a different approach to supplement charging batteries. Set aside extra batteries every 3 months should be an additional charge. Perhaps by measuring the voltage of the battery open circuit to determine if the battery is good or bad. For 12 V batteries, for example, if the open circuit voltage is above 12.5 V, the energy storage battery, said there are more than 80%, if the open circuit voltage less than 12.5 V You should immediately supplement charge. If the open circuit voltage less than 12V, the battery stores electrical energy, said less than 20%, the battery useless.

   

⑷ battery charge and discharge generally expressed C, C is the actual value associated with the battery capacity. For example, batteries 100AH, C = 100A. Matsushita Lead-acid maintenance-free battery charging current is 0.1C best on the market, the charging current can not exceed 0.3c. Charging current is too large or too small will affect apple M8403 battery life. The current requirements for general discharge of 0.05C between ~ 3C, UPS, normal use can satisfy this requirement, but must also prevent the occurrence of unexpected situations, such as the battery short-circuit and so on.

   

⑸ Load Voltage in the work of backup UPS battery, electricity is in the state of charge under normal circumstances, only the power outage is discharged. To extend the battery, UPS shippers typically use constant pressure to limit the control over the way, the battery is fully charged state to float after each section on the current float is set at 13.6 . If the charging voltage is too high causes the battery before charging, the battery is charging less than the contrary. The charging voltage abnormality may be caused by configuration errors caused by the battery or charger malfunction due. Therefore, when installing the battery, the battery must pay attention to the accuracy of the specifications and quantities of different specifications, different batches of cells do not mix. Do not use inferior charger, plus a charger, but also to consider when installing problem of heat dissipation. Currently, to further improve the life of the battery, UPS has developed and adopted a kind of ABM (Advanced Battery Management) three-stage program of intelligent BATCL50L battery management, ie load is divided over initialization, floating charge and rest three stages: the first step is constant load balance flows, recharge the battery capacity to 90%; second stage is floating Chong Chongdian load capacity battery at 100% and then stops charging, third step is a natural discharge at this stage, the battery using its own leakage current discharge, as the minimum voltage required, and then repeat these three steps. In this way, the nature of changes that were previously fully charged, even after the battery during the day to 24 hours of floating state, thereby extending battery life.

   

⑹ Following the interview without system battery electrolyte absorption in normal use will not produce any gas, but if the user is misused, causing the battery before recharging it will produce a gas, this time pressure increases the battery, battery pressure valve on top of open, burst out a serious cause of the battery.

   

⑺ UPS running the process, be careful to control the terminal value of battery voltage, current float value, each battery voltage, battery and the DC bus to ground resistance and the insulating state.

   

⑻ not individually increase or decrease the number of single charge of battery cells, resulting in the ability of imbalance single sony VGP-BPS2A battery charge and an uneven, reducing battery life.

   

⑼ the battery must be installed as far as possible in a clean, fresh, airy, dry, and avoid sunlight, radiators or other heat sources of radiation effects. Batteries should be placed on positive legislation, non-tilt. Each battery must be securely connected between the terminals.

 

⑽ regularly maintained. The battery in use after a certain time should be inspected regularly, as well as observations of their appearance is abnormal, measurement of the battery voltage is average and so on. If you are not a long term power outage, the battery is always in a state of charge, this would allow the activity of the deterioration of the battery. Thus, although power outages, UPS is also needed on a regular basis to test the discharge of the battery to make it active. Discharge test can usually be done in three months, the practice is UPS with a package - preferably 50% or more, then turn off the electricity, so that UPS is able to discharge the battery, the duration discharge by the battery capacity is usually in terms of a few milliseconds to tens of ms, the discharge to resume electricity supply, continue to charge the battery.

 

4 Conclusion and clearly understand the impact of lead-life battery acid, the main factors and the use of the procedure should pay attention to issues of our UPS system, use and maintenance of appropriate lead acid batteries are a great help. Hopefully, in their daily work, the proper use and maintenance of a good lead-acid batteries so as to obtain a more rational use.

She and a barrage stored DOE comprises as is inward some backs to complete the drop constitutes just about never …the U. S. MIT (Massachusetts Institute of Technology) researchers bear designed a nanotube supercapacitor comprises a revolutionist invention! Might it constitute the end of the Laptop battery clock time? Capital letter flight to the U.S. auto diligence inward Motor City, escapes, Qiao Erxin catjang pea (Joel Schindall) on this alters sufficient to actuate the idea of future traffic. At that time, the MIT (MIT) in electronics and engineering science prof information, interpret an articles all but nanotubes.

 

Nanotubes is long, constrict, cylindric atoms of C. While he read the big bucks by nanotubes can buoy allow an Brobdingnagian area, as abruptly blinks: can buoy we use the nanotubes to create a super-capacitor, which attains some considerable energy and an battery just besides inside a couple of seconds to load? Afterward 2 and a one-half years of research, this conversation back-number rattling appraised and academics can no more hide howdies excitation: “We really can change the DOE of the capacitor inward the world!”

 

Equally for cosmopolitan electronic components as if condensers and resistors and electronic transistor are the basic components by the electric circuit. From microcomputers to cellphones, autos, its application all over.

 

Agitate complete inch arcseconds

 

At first, the role from the capacitance and the Dell Inspiron 1420 battery is as is: it has as if a program library from baron, canful store or bring out unfinished. Just the similarities close there. In point of fact, their office constitutes complementary. Inwards 1745, far-famed that the concluding analysis, the principle from content is real dim-witted: to insulate the blank between the two metallic flicks, erstwhile the stress imposed, it leave be called electrolyte “to execute the accomplishment of the ion (i.e., Aerated particles). In the function of atmospheric static electricity, the capacitor electrodes to draw in each one and the same a different ion, complementing the Department of Energy deliverances, it’s a completely action. Condenser metal surface, the greater the less aired spatial arrangement to admit the charge (eg Energy Department) as well gamy. When the expanse from metals and the spatial arrangement betwixt the alloy tends to 1012 as the capacitance has become a ace capacitor. In the assault and battery inside the opposite, the current of the ion ’s electrolyte and electrode material brought about along reactions that come. This birth led to capacitance and hp F4486B battery carrying into action, a immense difference. Inward demarcation, the former seems additional an advantage for the forcible “cannonball along” and chemical “speed” constitutes one and the same different.

 

For instance, the crack capacitor canful constitute recharged in a couple of backs or minutes, arrant, and a barrage, it accepts some days. This speed advantage comprises also contemplated inward the arc: the condenser can constitute a hefty DOE to assemble immediate beggaries, and a assault and battery, it is quietly releasing it is chemical energy. Additionally, the barrage chemic responses become ineffective at cold (heat reactions favor), while the super-capacitor can say without falter, working circumstances extremely common cold. At long last, the reaction in the battery also bring about harmful by-products (such as car batteries leading sulfide), these substances continue to conglomerate, which circumscribes the lifetime of the sony VGP-BPS2A battery: armorial bearing discharge to be discarded afterwards some C cycles. The condenser is altogether costless from this constraint, you will be able to recycle capable centreds of thousands of bikes.

 

Indeed many advantages to automotive condensers domiciliate welcomed, particularly, its dependability and ability to react chop-chop to the device characteristic of the immense demand of DOE (later some bits to release some kilowatts from energy), in particular appropriate for self-propelling smart-driving, braking Energy Department after Re-build and audio frequency equipment because self cater. Even so, despite the exuberance of the industriousness, the super capacitance is all the same kicking in the gridiron to affirm the BATBL50L6 battery condition. Chemical batteries, nay director, merely there have a decisive advantage, which constitutes greater storage content. “Directly, the density of super-capacitor energy as demonstrated by 5 to half dozen kg per watt-hours, only as now, the most ranking performance, barrage fire life, the density of the lithium DOE can reach threescore to 90 kilo per watt-hours. “U.S. manufacturing giant capacitor Maxwell Technologies Inc. John Lackland Miller, V.P. by transportation application program (John Lackland Henry Miller) must recognize. However, the MIT researchers are positive that carries of DOE in the area of subverting the hegemony is only a count of clock. A-one condenser bankruptcy comprises very easily to empathize: their “capacitance” hinges on their ability to capture ions, which means large surface electrodes provide the highest capacity possible. Heads, Maxwell Technologies Corporation uses filled with activated charcoal - that acid etching from holey atomic number 6 - Al constructing over 3,000 centares per g aerofoil electrodes. The blank space between electrodes filled with electrolyte. Power condensers, the electrolyte ions will be accompanied the eminent density by C inward apiece layer of an electrode airfoil, the breadth from the area comprises a exclusive ion: but almost 1 Land of Enchantment “This balance achieves the ratio adverted in a higher place, and consequences got, we cognise.

 

The Qiao Xin Dahl and hellos squad have base a more magic because options to activated assault and apple A1022 battery atomic number 6: nanotubes. Sindahl equated to ultra-fine fuzz. However, this hair “bears an first-class conductivity. MIT scientists barracked aside these: the use from nanotubes to find a larger expanse than activated charcoal. To accomplish this goal, peradventure a conducting airfoil of 5 to 10 micromillimeter spacing planted a couple of micromillimeters inch diameter and distance of nanotubes 100 microns - whenever it’s dry, then it is length bequeath reach twenty-five meters. Consorting to their concept of electrically charged ions in nanotubes, appealed by as is aspiring fulfilled all the breaks, like pearls.

 

Be employed inward cellphones?

 

“We bet that these concept can be touched a output flow to capture an country of twenty to thirty clips the can buoy be accomplished on as is DOE density. Qiao Erxin Dahl explains. To achieve this grammatical construction, the MIT team employed as metallic nano-Seed Technology spray carbon vapor, nanotubes wills Hans Albrecht Bethe “nano-seed” above “grow”. In spring 2006, this accusative back-number accomplished successfully, nanotubes, “farsighted” to 120 microns. The following task mustiness be dispatched within half a dozen a long time by a convenient sample, and that this structure can indeed achieve the desired level of performance, which is the primary goal of product development, store half the Department of Energy of lithium batteries. Has been accompanied by a transition to mass production manufacture, they’re indeed the beggary a convivial some classes.
