Digital battery

Battery industry is another important component of the energy sector is the economic development of a new hot spot in 2006, the United States there are two top ten science and technology plan for the proposed battery , lead the industry Laptop battery acid, one third of total sales, and electricity, transport, development of information industries is closely tied to the truck automotive and other transportation and powerful system-wide uninterrupted power supply in the control of social production and business activities and human life, an essential product. The industry lead acid battery is the twenty-century and the first application of the most promising prospects of new green energy systems, while related to the implementation of national development strategies sustainable.

 

In recent years, lead-acid battery technology continues to grow, mature products. Structure progressively from the IBM ThinkPad T60 battery optimization and improvement, maintenance free batteries widely used, is still military, civilian transportation equipment, a device power supply important for our country become the world of big auto-producing countries play an important supporting role. VRLA batteries, gel batteries as backup power, large reserves of power components of heart, his production has become an important basis for economic development in the sex industry. Promising lead acid battery industry.

 

The main raw material for lead-acid batteries - lead repeated use recyclable, provided that the introduction of battery recycling waste related industrial policies, the right to direct the market, we can really solve the shortage of non-China Non-ferrous metals, lead pollution, resource and environmental problems a lot. Therefore, a correct understanding of the industry of storage Dell U4873 battery, the status quo, identify trends and effectively solve their own problems, is the recycling of resources and building a conservation-oriented society, is an effective way of scientific development in the national economy.

 

Firstly, the status quo of China’s lead-acid battery industry

 

Since its accession to the WTO, as well as the domestic industry and international battery, encourage manufacturers to increase investment in China, cause the rapid development of China-acid battery industry, the growth rate Annual over 30%. At the same time as the increasing demand of international market, China became the world’s largest exporter of lead acid batteries. Involve China, the acid hp 367759-001 battery technology and the gap between the international level was not evident, car batteries at international advanced level, use the power, the battery technology for electric bikes near the international advanced level.

 

After more than 20 years of development, maintenance free battery and sealed storage has achieved great success in technological advances to make lead-acid batteries, not only in transportation, military and national defense are widely used traditional areas, and is widely used in solar photovoltaics, wind power, communications power supply, power conversion and distribution, rail, maritime communications, starting, lighting, power, UPS power. Technological advances have contributed to the rapid development of industry stockpiles, making it one of the branches emerging future. However, because the lead, the main raw material-acid batteries - lead prices in the second half of 2004, a substantial increase, and continued to maintain a high price to run, lead-acid sony VGP-BPS2A battery drop-profit sector profit.

 

In recent years, along with changes in market demand, lead acid batteries continue to improve methods and processes of production, manufacture, scale, the specific energy battery, life cycle, the performance, consistency, use of safety and environmental protection continues to increase. With supply electric bicycle battery such as the development of technologies to high temperature drying is progressing rapidly. Generally believed that high temperature drying can increase the lifespan of the battery in recent years, and the ratio of negative additives also accumulated a large number of parameters, and identified a number of ordinary experiences. At home for other advanced technologies, such as liquidation of battery type, bipolar type, thin plates, etc. are still at the research stage, there is no mass production.

 

Status report of our patented technology, the toshiba PA3191U-2BRS battery industry in recent years, the overall line of development of defense technology is the improvement of the battery structure and evolution of the battery. The foreign patents are primarily related to cash thin bipolar plates lead acid battery, using the module structure of cells and colloid electrolyte lead battery sealed. Therefore, our proprietary technology with foreign countries is lagging a bit.

 

Secondly, lead-acid battery industry, the status quo and problems of environmental protection

 

After years of construction and development of China’s lead-acid battery industry has been primarily consisting of the system and showed trends of rapid development, environmental issues also made a breakthrough, at present, fumes of lead from China and the dust, sulfuric acid mist and methods of water treatment techniques and was essentially mature, medium and large lead acid battery manufacturers constantly increase the technological transformation efforts and modernizing process equipment commonly used in high efficiency cartridge precipitator replacement electrostatic dust-collector style, using a wet cleaning fumes of lead dust, with turbulent Ball sulfuric acid mist cleaning treatment fog absorption tower, flocculation reaction of lead-containing waste water treatment of acid technology to eliminate or reduce the impact of pollutants on the environment, producing a continuous improvement of working environment, most large and medium-sized manufacturing companies to achieve cleaner production, it is partly thanks to the certification of the National Environment.

 

However, for several reasons, the process of cell production of the pollution problem has not been well resolved, particularly in some of the many small and medium enterprises serious pollution problem in the production process: from Many manufacturers, small-scale, are more ecprice polluting, the uneven quality varies, some lack the environmental conditions of the factory workshop style rush into mass action, approximately one quarter of companies without approval Environmental Site of unauthorized construction, plant control of pollution are not complete, production is not strict measures of environmental protection and industrial safety and hygiene conditions, the operator and dangers to the ecological environment. Production permit system does not strictly own production, plant protection of the environment in respect of this point. Although our country since 2005, implementing the system of production permit, but because of the approval and implementation, there are problems and do not encourage manufacturers to achieve truly clean production, and many Manufacturers are not the legalization of Compliance (currently 930 companies were certified homes), causing serious environmental problems. Laws relating to the protection of the environment there is much more imperfect and not entirely satisfactory. Against polluting enterprises, protection of the environment and the fines and other ministries is limited, companies can not compare the social costs of pollution. In addition, the country does not specify protection for large and medium-sized policies apple M8403 battery manufacturers, and local departments of environmental protection is also for the management of small manufacturers of batteries, only the emphasis of regulation on businesses large and medium, reflecting firms’ costs of treatment of large and medium, monitoring costs, the “three simultaneous” evaluation fee, as a heavy burden. 

Introduced the use of nickel-metal hydride battery of new products also accelerated the acquisition of all the heat, of course, it is unique “temperament” as the energy density, the number of charge cycles and more details ‘memory effect is small, non-toxic metals such as cadmium, mercury are also a number of advantages achievement of nickel-metal hydride Laptop battery position in the bull market.

 

With all the hands in nickel-metal hydride batteries steadily increasing number of scientific leap in the use and maintenance has gradually at the sight of attention. As we all know, the brand Ni-MH IBM ThinkPad R51 battery life can be charged according to the official request that 500-1000 times, but this is actually a good value, and often do not respond to such a life. But as a sensible use of chargers, more in depth understanding of nickel-hydride batteries, metal, we have left to do, “longevity”.

 

1. Under normal circumstances, the new nickel-metal hydride batteries contain a small amount of electricity we buy on driving charge and then reuse. However, if time battery plant is quite short, electricity is sufficient to recommend use first and then reload.

 

2. The new nickel-metal hydride batteries to buy a general charge to go through 3-4 times and use of, performance can play in the best condition, many of my friends for the first time, the prosecution encountered a small problem, for example, the first charge did not imagine the number of PP film so many? In the 3-4 times after charging and the use of all be resolved.

 

3. Although nickel-metal hydride Dell Latitude D820 battery memory effect is small, as much as possible is recommended after each use finished loading and is full of time, do not charge you would use for one count and then. Only longevity, “Oh, the important point.

 

4. The battery charging, the charger should pay attention to the heat surrounding the deliberate use of what wind there too is no need for fans, but noted that the shipper should not put too much debris around. Ordinary users the process of using the battery, the battery is often not a dedicated storage bag; users to replace the battery, will acquire the habit of easy storage battery, regardless of where the place is clean and moist . The consequence is that the battery they get dirty easily, easy-to-metal contact, such as keys, etc. contact, easy to moisture, and it is the enemy of batteries. Recommendation: Users should set up a special cell to place points and keep the battery clean. To avoid problems such as loss of electricity to keep the Dell KD186 battery and contact points of the battery to both ends of the inner lid clean, if necessary, use a soft, clean and dry pasture.

 

5. A long time did not have time, remember to remove the battery from the storage battery, placed under dry conditions recommended brand of battery in the box to prevent short-circuit the battery.

 

6. A long time without nickel-hydride batteries in the metal shop a few months later, the battery naturally in hibernation “state”, the battery life considerably reduced. If Ni-MH battery has been placed for a very long time, I suggest you begin with the slow charge is appropriate to impose. For another important issue at stake here: for Ni-MH HSTNN-LB31 battery, the battery must be completely discharged, then save, store, or online? Both points of view very different from what it should be used? Many people think that we should adopt the first, but I thought that to save the battery charge is reasonable. Because: According to tests, Ni-MH battery to save the best conditions to save about 80% charged. Because the nickel-metal hydride batteries self-discharge rate is high (10% -15% per month or almost), if the battery is completely discharged, then save it for a long time not to use the ‘battery-discharge phenomenon will discharge excessive battery, may damage the battery. Do not believe? So you think to buy a new nickel-metal hydride rechargeable battery is not all there is electricity, which is the reason. Recommendation: Apart from correcting the wrong point of view, maintenance of the battery to start in the right direction, otherwise it will backfire.

 

7. There are many messages from friends post questioned how to meet Ni-MH? After investigation, after many specialists battery reach a unanimous conclusion to remind friends. Do not nickel hydride metal discharge the sony VGP-BPS2 battery, excessive discharge may cause the failure of pricing to harm is much greater than Ni-MH battery memory effect of the battery itself!

 

8. Auto multimeter test battery is full or not. Ni-MH batteries in general charge before the voltage is below 1.2V, filled with normal voltage is 1.4 V or later. We as a judge, also very easy to judge the condition of the battery.

 

9. Chargers can be divided into fast charge and trickle charge. Low load current is small, typically around 200 mA, such as our common load current is about 160mA. His long-time charge, 1800mAh Ni-MH toshiba PA3399U-1BAS battery should be 16 hours or more. Even if I was a little slow, but the charge would be filled very full, and do not hurt the battery. Fast charge current is usually in the more than 400mA, charging time significantly reducing the number of .3 to 4 hours can manage that, but also won the affection of all. Several types of fast charge, prices vary. Therefore, we often have questions about the same load faster, why the price is a big gap in it? Good charger in particular is a good fast charge brought against over-charging protection function, for example, we have a common understanding Acura Panasonic BQ 390 charger has been particularly noteworthy in this regard, excellent software chip capacity charge the battery while it also brought evil upon the battery, quick charger minimized.

 

10. Conflict: trickle charge does not hurt the battery charging time is too long, however; fast charge can save time, but there is damage to the battery, even if the surface is the world need the best degree Panasonic BQ390 charger only very good harm reduction, but not totally avoided. Contradiction can be resolved is to buy a quick charge and a trickle charge. Quick charge with the load for some time, for example, 5.10 times after the transition to slow Chong Chongdian once or twice. This apple A1078 battery performance to return to a higher state.

 

11. The batteries are commonly used battery, four or six, and this time, to maintain the balance of each cell is very important, otherwise, due to a battery problem has affected the work of the entire battery. First, the battery capacity and ensure consistency, the best place to buy the same brand of the same type of battery time. Then the internal battery power to maintain consistency, simply, is that the electric battery is either full or empty. If there are more groups in the composition of the battery, you can try to “select” look. Means that the specific capacity, similar to the battery voltage and other parameters in one set of battery cells in series, due to poor conditions, under normal circumstances let endpoint measures after the tension and son of red blood on it.

 

12. Speaking on the last charge and discharge.

 

Top of the range of NI-MH Aspire 3000 battery charger with battery test delta-V to determine if the battery is full. When the curve of discharge voltage of the battery and is somewhat similar to the beginning of a more rapid rise, followed by rising slowly until the stuffing is good, the tension began to decline rapidly, but decrease in not very large. Before commonly used nickel, cadmium batteries are also similar, but drop the speed and the amplitude was higher than the NI-MH. Most chargers on the market type (less expensive) is often used is the value of the charge pressure, such as the elderly GP 1.4V Rechargeable value Po is the pressure that is precipitated at 1.4V when the battery voltage, because there is no difference, and charge on the end. Such a result is often that the battery can not be bridged, particularly in some older battery due to increased internal resistance, the real addition to the low voltage battery. And this charger currents tend to be smaller, often charging more than 10 hours. Using Delta-V cutoff automatic charger, since it can precisely control the load time, use may be more reliable high-current load. High charging current nickel-metal hydride battery for damage and do not want to imagine the contrary, the use of DC current, but also require high current load. The first is a matter of time, not talk. Then, Ni-MH battery has a characteristic, that is, the higher your current rate, it can release the most common, and now is tigre DC electric current is not small, so relatively speaking the use of relatively large load current is a choice, you can clean the toshiba PA3191U-4BRS battery is added. General 5 charge current should not exceed 1.5 C, C to the battery capacity is 1000MAH batteries, not more than 1.5A. I usually carried with the load 0.5C (my charger with adjustable current). Discharge zone, in normal circumstances, DC Black can be a burden on Na Qu, NI-MH little memory effect. However, in a period of time after use, and the balance of the cell to activate the battery when the battery discharge and control the termination voltage. NI-MH battery termination voltage of 0.9 V, the discharge time careful not to over-discharge, the 0.9V for each battery when it may stop the rejection file. NI-MH battery is not powerful nickel-cadmium batteries, the overcharge and over discharge and is more sensitive to high temperatures. Charge and discharge temperature. In general, do not let the hp F4809A battery temperature exceeds 45 degrees. When the battery is fully charged, the battery will be hot, filled with large current when the temperature is 42 degrees and not more than 45 degrees, otherwise life will soon be reduced, the battery internal resistance will increase. Also, the load of the battery temperature is higher, and so on until after the cooling of its rechargeable battery, charging money for having to wait for the freshness of the battery. After a long time is not re-using, it is preferable to activate the battery to discharge a few times. Usually used in time to pay attention to maintaining the integrity of the wrapping paper, can not be broken in order to prevent short circuits. Do not fight the impact of the battery, do not fire and so on.

Vanadium redox batteries (VRB, VanadiumRedoxFlowBattery) is the largest and most technologically advanced, closer to the industrialization of high fuel cell performance reversible, with a great power, high capacity, high efficiency, low cost, a long life and a series of unique green benefits of wind energy, photovoltaic energy, energy peaks, distributed power generation, electrical storage military vehicles of municipal services, base station communication , power supplies UPS has a very wide field of good prospects in Japan, Canada, the United States, Australia, Western Europe and other countries and regions have begun to replace the capacity of small, short life, pollution a large lead-acid batteries.

 

With the rapid development of the vanadium Laptop battery technology, the vanadium battery is required to make a human being without precedent is of great importance and large industrial energy revolution!

 

Advantages of the vanadium battery

 

Compared to other food chemicals, vanadium battery has obvious advantages, the main advantages are:

 

1. Big Power: increasing the number of single cells and the area of the electrode, you can increase the power of the vanadium battery, the commercial demonstration of American power in the vanadium IBM ThinkPad R40 battery is running has reached six megawatts.

 

2. High capacity: an increase in the volume of electrolyte, you can arbitrarily increase the power of the vanadium battery until gigawatt hours or more, increasing the concentration of electrolyte, you can multiply the power of vanadium batteries.

 

3. The efficiency is high: When the vanadium battery electrode high catalytic activity, and positive and negative electrode active material were stored in the storage tank positive and negative electrolyte, preventing the material of positive electrode and negative active self-consumption of a discharge, charge the Dell XPS M140 battery of vanadium and discharge energy conversion efficiency up to 75% or more, much more that 45% of lead acid batteries.

 

4. Long life: When the vanadium battery positive and negative active material to exist only in the positive and negative electrolyte, charge and discharge the battery when no other phase-change policy, can not damage the battery deep discharge, long battery life. Canada Now VRBPowerSystems longest commercial demonstration module vanadium battery has worked more than 9 years, the burdens of life-cycle pulse of more than 18,000 times higher than the fixed type lead-acid battery 1000 times.

 

5. Speed of response: the heap is full of electrolyte hp 346970-001 battery of vanadium could be launched at a moment in the process of filling and operation requires the execution of only 0.02 seconds to turn the state, response time 1 ms.

 

Expenses 6. Perhaps snapshot: the electrolyte can be achieved by replacing the battery Vanadium instantaneous load.

 

7. High security: vanadium battery, without the potential risk of explosion or fire, although the mixture of positive and negative electrolytes is also non-hazardous, but the temperature of the electrolyte was slightly increased.

 

8. The cost is low: In addition to the ion exchange membrane, components of the vanadium battery, the cost for most low-cost carbon materials, engineering plastics, materials, sources of wealth, easy recovery, not of metal valuable as electrode catalysts, and low.

 

9. Vanadium VGP-BPS2C battery location large degree of freedom can be fully automated transaction closed, no pollution, easy maintenance, operating costs low.

 

Vanadium battery market outlook

 

Wind

 

Wind generators should be equipped at present is roughly equivalent to 1% of its power lead-acid batteries are used in emergencies to protect the revenues of the fan with a fan, another machine is also required Typhoon for each power is roughly equivalent to 4% of its power back-up battery. As the grid has become a bottleneck in the development of wind power with the explosive growth of wind energy, wind energy and power struggles will become stronger over the network to reduce the impact of the substantial increase in the use of wind energy at the same time win a huge difference peak and valley power systems, wind farm will be required with a power equal to its power 10 ~ 50% of toshiba PA3399U-1BAS battery storage dynamics. For fans outside the electricity grid, you need a greater proportion of flow storage batteries.

 

As the fan there is lead-acid batteries currently used in small capacity, short life, poor stability, maintenance time and effort, causing pollution and other serious defects, manufacturers fan has been looking for a better alternative to lead product battery acid, I believe, has many outstanding advantages of the vanadium battery can replace the existing lead-acid batteries, thereby building a wind farm dynamic system of energy storage, has greatly improved the efficiency and effectiveness of wind farms to promote the industry of wind energy to develop better and faster.

 

PV

 

According to official statistics, in recent years, the growth rate of average annual global PV modules up to 30%, the photovoltaic industry has become the world’s fastest growing emerging industries. In particular, in 2008, the world’s total installed PV capacity of 3 GW.

 

As its name suggests, the photovoltaic power generation needs sunlight, once in the evening and on rainy days is not like electricity, and thus the need for apple A1012 battery energy storage electricity because of power lead-acid battery, capacity, life expectancy is very limited, I think a number of advantages of an outstanding series of Vanadium Batteries will serve as first choice for battery storage of photovoltaic energy.

 

A peak power

 

Grid shaving up was the primary means of pumped storage power plant. Nearly three decades, the developed world in the development of power plants pumped storage power faster and faster. Pumped-storage power plant in the world’s fastest growing installed capacity of the largest in Japan, followed by the United States, Italy, Germany, France, Spain, Japan and the United States were station pump-turbine installed capacity of over 20 million kilowatts.

 

Pumped Storage Power Station due to the need to build upper and lower reservoirs, subject to conditions more limited geographically, in lowland areas is not easy to build, and covers a large area, the high maintenance costs . Vanadium station storage TravelMate 290 battery, without geographical restrictions, location of free, compact, low maintenance cost. We can expect, with the battery technology develops vanadium, vanadium station battery energy storage will gradually replace the pumping station-turbine in the network plays an important role in peak shaving.

 

Transportation Services

 

As the world continues to accelerate the process of urbanization and the continuing growth of motorization, pollution, car exhaust, urban air pollution has become the primary source of pollution. Vigorously develop energy-saving, environmentally friendly alternative to traditional fuel cars electric car, has become the consensus of the people. With the rapid development of Dell RN873 battery technology of vanadium can be seen, has many outstanding advantages of vanadium in batteries for electric vehicles (especially buses), electric motorcycles, electric bicycles, electric boats, traffic lights, streetlights and other major areas of scenery to play an important complementary role.

 

Communication Base Station

 

Base stations of communication and communication needs of the battery as a back-up supply chamber, and usually not less than 10 hours. Operators in terms of communications, security, stability and reliability and longevity are most important in this area, the vanadium hp PB991A battery is a lead-acid batteries can not match the rewards.

 

UPS Power Supply

 

CCID Consulting research shows that in 2007, UPS market has continued growth trend, primarily because of rapid and sustained development of China’s economy caused by the decentralization of UPS needs of users, making the industry more more business-to-UPS produces a sustained needs. The next few years, the UPS product development towards greater availability, security and features integrated, intelligent, and humane.

 

Currently, China’s UPS market, strong demand for large power, batteries are safe, stable and reliable batteries of vanadium in this area, as opposed to lead-acid batteries in terms of power, safety and stability, or both have an absolute advantage in life.

 

Power Distribution

 

In today’s society of energy and electricity supply, quality, efficiency, environmental protection and the growing requirement for high security and reliability, large-scale power was due to their own failures can not meet this requirement. With the rise of the distribution of the central, large central power stations will gradually decrease. I think the vanadium battery is the first in a hospital, command centers and control, data processing and communications centers, commercial buildings, entertainment centers, vital government services, pharmaceutical and chemical industrial materials, Industries precision manufacturing play an important role in the distribution of power.

 

Military Reserve Power

 

Vanadium battery may also be military bases, command centers, military and other military departments play an important role in charge storage.
