Digital battery

In recent years, with new lithium-ion secondary battery in top sports energy, environmental protection, security and other lithium breakthrough technology industrialization of electric vehicles entered an important phase of development. August 25, 2006 Lithium power ion battery technology and industrial development of the international forum held in Beijing, Zheng Ji-chun, deputy director of Beijing Municipal Science and Technology Committee briefed the participants on electric vehicles in Beijing and lithium-industry developments ion battery. hp Pavilion dv2000 battery  hp Pavilion dv6000 battery

 

Development of electric vehicles is required

 

Zheng Ji-chun said that in addition to global energy crisis, the background, development of electric vehicles in Beijing there are two main reasons, namely, the requirements of environmental protection and the Olympic requirements.

 

According to statistics, from the end of June this year in Beijing reached 2.73 million motor vehicles to maintain, primarily in China, with an annual growth rate of about 15% is expected of By the end of this year will exceed 3 million euros. With the amount of car ownership has increased year by year, commuting from his people very practical at the same time, has also caused environmental pollution, noise, oil tight and so on. According to the experimental units, each fuel vehicles daily gases emitted about 0.6 ~ 0.9 kilograms, the atmosphere in Beijing more than 70% of oil, over 60% of nitrogen oxides from exhaust from cars, direct discharges of pollutants from car the total concentration of the contribution rate has shown an upward trend. Compared with foreign countries, emissions from motor vehicles in China caused by air pollution is much higher than the United States, Japan, France, automobile exhaust has become the capital of main sources of air pollution.

In addition, the 2008 Olympic Games will be held in Beijing, according to his previous experience in successfully hosting the Olympic and pure electric vehicles have become the host city for the Olympics earlier promotional theme of Green Olympics. In 1996, the United States Olympic Games in Atlanta, has invested more than 250 vehicles from golf carts electric and 15 electric buses in the fleet composition of the green, the Sydney 2000 Olympics, has invested $ 400 pure electric vehicles by the composition of the fleet green 2004 Athens Olympic Games in South Korea Hyundai offers a number of vehicles, pure electric vehicles for the marathon and marathon relay of the torch lead car. Solemn commitment of the Beijing Olympics would be “tight control of exhaust gas from vehicles and other sources of emissions of pollutants and the urban daily average concentration of major pollutants to ensure that weather conditions over unfavorable to achieving the standards of air quality required by the International Olympic Committee.”

 

Zheng Ji-chun said, according to these reasons, Beijing has the responsibility and the need to develop electric vehicles is a difficult and urgent.  IBM ThinkPad X60 battery FRU 92P1141

 

Pure electric vehicles will be used for Beijing Olympics

 

According to Zheng Ji-chun erected the development of Beijing Electric Vehicle fundamental objective is to reduce automobile pollution, adjust and improve the structure of energy consumption and to achieve urban economic development, social and environmental development. To this end, the development of Beijing electric vehicles throughout the deployment of a three-pronged: First, select the bus to promote the use of electric vehicles as the main areas, the second is to promote research electric vehicles, development and industrialization, third battery of active power, etc. advanced technology vehicle research and development.

 

Use of electric vehicles in the Olympic Games, Beijing has also made a corresponding development plan: First, 90% buses and all municipal regulations (environmental and postal) car for the electric vehicle, the second is research and development of pure electric vehicles to improve traffic pollution, three Olympic Park with a zero emission vehicles and ultra-low emission vehicle.

Zheng Ji-chun said, according to the presentation of preliminary ideas for pure electric vehicles as the representative of the zero-emission and ultra-low emission vehicle, it will direct the Beijing Olympics, applied to the major bus lines , focusing on regional and sports centers. To this end, Beijing attaches great importance to electric vehicles in recent years, research, development and promotion application. It is understood that, “15″ period, Beijing took the 863 “national” plan major projects in pure electric vehicles, electric buses and bus research and fuel cell development tasks, and became the National Science and Technology has established four model cities in the world of electric vehicles. Science and Technology Commission of Beijing Olympics is also used in the development and application of electric vehicles, one after another in this area, science and technology funds invested around 2 billion euros, thanks a series of major scientific and technological projects and scientific and technological projects carried out much work, research and development, manufacture, application to promote the three links in the detail and meticulous deployment.

According to reports, the search for electric vehicles and development process, Beijing has made a series of technical achievements with the rights of independent intellectual property, access to more than 20 patents, developing technical specifications and standards of undertaking of 22 items related companies have independent intellectual property rights produced electric vehicle capabilities, and Beijing R & D of electric vehicles has almost reached the practical level. A number of lines through a model for nearly a year to run the Beijing developed independently of the overall performance of the electric passenger car pure principle has been found practical electric vehicles and key components of the reliability and applicability of the problem was basically solved, the mileage intervals were failure to reach the level of conventional engines, internal combustion, can basically meet the bus and use requirements during the Olympic Games.

 

Lithium battery car problem solving Olympics

 

Electric vehicles are crucial cycle of battery life, safety, cost and application problems efficiently. Electric vehicles in Beijing in the development and commercialization process has also been confronted with these obstacles, the battery technology for power, performance and cost constraints become an issue of wide application of commercial electric vehicles of the neck strangulation.

 

According to Zheng Ji-chun, at present, Beijing, developed mainly in the location of production of electric vehicles, lead to greater capacity, battery acid and lithium-ion batteries as power, fuel cell technology fuel is still at the track and the stage of research. With the trial operation in a number of bus routes and found that the use of lead acid batteries for electric vehicle driving range is shorter lifespan is short. In addition, lead acid batteries, there are still bulky, not environmental protection and other shortcomings. And compared with lead acid batteries, lithium-ion battery is a high energy density, high operating voltage of the green cells is considered to power future electric vehicle battery, one of the best choices, but the high cost of investment of time. It is understood that an electrical bus with 400-an-hour lithium-price ion battery to hundreds of thousands of dollars to reduce the cost of lithium-ion battery is an important element of future research.

 

Beijing attaches great importance to the lithium-ion battery and key material for research and industrialization. It is understood that, “15″ period around the lithium-ion battery research and development and implementation of the Science of Beijing Municipality and Technology Commission has invested more than 4000 million science and funds technology, organization and implementation of lithium, the material of the lithium ion battery cathode of manganese oxide from industrial technological development “,” pure electric vehicle lithium-industrialization of ion battery research and development ” and a significant number of scientific and technological projects, support the cathode material, the diaphragm and other essential materials to a series of lithium-cell research ion. Thanks to scientific research and technological research on key technologies and development of lithium-ion battery Beijing and key materials for the industry has made a breakthrough. Current cathode materials have been developed with intellectual property rights independent of the lithium-ion batteries key information necessary for the synthesis of manganese oxide lithium technology to solve an international structure of lithium manganese spinel oxide the synthesis of key technical problems and the lithium manganese oxide charge and discharge cycle stability of the world with problems of poor technique, and has made lithium oxide and lithium manganese oxide industrialization cobalt material.

 

However, Zheng Ji-chun also emphasized that lithium current China-materials separator ion A1060 M8403 battery necessary to rely solely on imports, prices cost high-powered battery separator materials represent over 30%. If the membrane material to enable location will significantly reduce the cost of battery power. For example, the Olympic 400 with an electric car when the lithium-ion battery, divide the cost accounted for 16 million yuan, if the membrane to allow localization costs will save half of the membrane. Currently, a number of units are organized scientific research, and some have already entered the pilot phase.

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.

Some basic methods

 

First presents the basic methods, these methods, you may already be familiar with, but if the flexibility of demand, will greatly increase battery life.

 

1, using energy saving mode mobile phones

 

Take time to understand the interface of your smartphone, you will find the settings can be saved by changing the Laptop battery. Note that these parameters are related to many aspects of the use of mobile phones, it may be in different parts of the interface. But for most cell phones, such as Windows Mobile and BlackBerry mobile phones, the option in the Settings menu.

 

We must reduce the brightness of the screen by default, because the climax will consume more energy. But also shorten the time fire background. Although this may sometimes make you feel very cool, but its benefits are obvious.

 

2 for your cell phone to find stuff online

 

For example, there specifically for a new generation of Apple’s iPhone 3G page on how to save electricity. In addition, there are few manufacturers not to provide useful skills, like the BlackBerry and Windows Mobile website.

 

3, if there is an opportunity to take time to load

 

The use of mobile phones are lithium-ion IBM ThinkPad T40 battery, so it is quite possible and even recommended. If the conference room of the outlet or load terminal of the airport, to take full advantage of every opportunity to recharge their cell phones. Recharging while driving is a choice, you use a car charger for mobile phones directly from the handset manufacturer or carriers to search, you can also purchase companies such as APC provide a universal charger.

 

4, using calls, rather than e-Mail

 

In the cellular network, the data connection used to connect the battery is the voice of two to four times. For simple communications, call or send text messages rather than e-mail.

 

Effective management of your software

 

Many of us tend to have used an operating system. And the request to make your smartphone to make it useful and interesting. But regardless of the operating system or applications, will be the exhaustion of VGP-BPS9 power, forcing them to manage and reduce their energy consumption.

 

5, upgrade the operating system

 

Maximum power consumption is the operating system. In each version, manufacturers are still improving energy consumption, in a timely manner to update your operating system.

 

6, using a simple ring

 

Need to use the cell phone with music ringtones processor, leading to consume more energy. A simple, standard ringtones should not be such a treatment.

 

7, minimize the use of the push

 

The most popular is probably the smart phone applications, push e-mail, which requires little time to check the phone messages. This consumes much energy, and you can use settings on the server or the phone itself is set to adjust the cell phone every 10 minutes or half an hour to check the information first. Clearly, this must become accustomed to the use of instant messaging users to coordinate, but on saving hp Pavilion dv4 battery power is really worth doing.

 

In addition to push e-mail, there are a number of other applications and Web services such as instant messaging, navigation tools and stock, news, sports and weather information will be updated periodically. You may not be aware that if you ESPN updated every five minutes, will soon complete consumption battery power. So when you do not use these programs and websites where close.

 

8, weakened garrison functions

 

When news is old, do you really need to phone to vibrate? New messages for the closure of the auditory or visual alarm, or at least have the choice of closure, for example, to retain only your boss and inform parents.

 

Effective management of your hardware

 

In the past, the mobile phone is only a radio for voice calls. Now, in addition to cellular voice daily and data services, wireless, smart phones have Bluetooth, Wi-Fi radio and even GPS.

 

9, turn off the radio does not use

 

The radio is on, even without the use of considerable VGP-BPS13 energy. Learn how to switch off the radio smartphones. For example, for most Windows Mobile phones, if the hold the home button and keep for a while, a dialog box is displayed on mobile phones, you can open this dialog, or turn off the radio.

 

10, note that the time to call

 

When there are too many people trying to access the cellular network, mobile consumption of energy will be even more grande.Malgré this, you may also be reluctant to 3:00 call or answer the phone, but if you’re in the western region of a night owl, 7:00 is what one might call the best time for the eastern region.

 

11 know where you live

 

Studies have shown that the network will be a place where electromagnetic interference to become unstable. This means that in the outdoor park in the mail or call electric hospital less.

 

Similarly, the poor areas of radio coverage will be unstable. If you are in the areas covered by bad guys and you do not like SMS, then turn off your radio.

 

12, using low-speed network

 

Using HSPA or EV-DO as well as using EDGE or 3G services, such as 2.5G services, 1xRTT need more power. All applications require a maximum speed, you will notice in May 2.5G and 3G services, the major differences, such as checking your email. Some phones, such as the Apple iPhone 3G, you can jump to a network access low speed, thereby saving the Dell Inspiron E1705 battery power. If your phone has this feature, at the appropriate time to use it.

 

13, using a wired headset

 

Bluetooth headset to use their own needs for radio frequency use the battery. Using the wired headset does not use a separate radio frequency, will make your cell phone to use longer. And using a wired headset call quality is better.

 

14, using self-closing feature

 

Some phones, like BlackBerrys, mobile phones within the time specified, close parameters. Phone automatically turns off at 11 am, at 7:00 to open. In this case, you do not have to worry about the.

 

Battery Maintenance and Repair

 

On the way to maintain the battery some outdated ideas still exist for the old nickel-chromium batteries, power is often proposed that ion battery depletion, after full power, but for lithium today - The practice should not be so, and people still, and even some instructions in the user manual is wrong.

 

So here are some tips to ensure more usage time of battery life.

 

15, early and often responsible charge

 

Experts suggest that as far as possible not to pay very little when it is charging. But there is one exception, every few months they should be on your battery is completely discharged, then recharge. In fact, this does not apply if the battery life, but you can reset your phone to load the firmware to provide a more accurate value.

 

16, to keep the battery cool

 

Do not put your cell phone hot place. Experts said this would reduce the capacity of the storage battery.

 

What’s happening in the money

 

17, a spare battery

 

If you want to use the phone for a long time, then buying a laptop toshiba PA3465U-1BRS battery. Depending on your phone model is different from the battery usually costs only U.S. $ 10-30.

 

18 for long battery life

 

Such cells are usually caused by telecom operators and handset manufacturers to sell, they should be larger than the standard battery, this may be filled with the entire phone. But the cell can use a longer time, so you will not be forgotten to worry about a battery backup.

 

Depending on your phone model is different from the price of this long battery life of 20 to 30 dollars.

 

Note that the two techniques above do not apply to Apple’s iPhone because the iPhone battery cell phone is not replaceable.

 

19, carrying a portable rechargeable battery

 

These products are now endless. For example, Medis 24-7 Power Pack fuel cell technology to recharge the apple M8403 battery while the solar charger Solio provides. Portable battery using technology more conventional batteries, such as the Big Wave Power in EnergyPORT. Completely full-power portable battery for your cell phone offers 30 hours of battery life.

 

20, buy a spare battery

 

Battery backup as a method of last resort, and turbo charge manufacturers Cellboost like to buy. This battery lighter, cheaper, and not burden of bulky battery, they are reserved for emergencies.

 

Obviously, if you follow this advice, you may not need emergency aid. Pay more attention to your cell phone battery, they will work longer.
