2012 Shanghai lithium batteries Auto to realize industrialization

2012, Shanghai will have an annual production of 100 million Li-ion VGP-BPS9A battery when the power and 6 million sets of the battery capacity of the system. Recently, projects in key high-tech industrialization of Shanghai, the new lithium energy auto project-Ion Battery “Investment signing ceremony took place in the urban area of Shanghai, the Shanghai Aerospace Industry Corporation , Shanghai, Space Power Institute, Ningbo Shanshan Co., Ltd. and other shareholders of the signing of the Quartet the first 90 million yuan of investment agreements. The next year World Conference Expo, two cars lithium - ion hybrid and fuel cells, will serve as VIP cars first.

Space technology for new energy vehicles

Shanghai Institute of Space Power Hua Jiang, deputy chief engineer of the introduction, the Institute started in 1998 dedicated to space-use lithium-ion VGP-BPS10 battery development and management of electrical systems. In 2008, technology in China for the first time successfully applied in the “Shenzhou VII” companion flight. In 2005, they began to cars lithium-ion battery and systems management technology research Power, in cooperation with relevant universities and companies working together to build dual-use high-power lithium-ion battery platform development system.

“Although the satellite and automotive lithium-ion battery is not one thing, but the technology is not geography.” Jiang Hua introduced with the flight of small satellites, the average life of three years, around the Earth 10 times a day, a total of more than ten thousand to go through second charge and discharge process, during which the state must guarantee the stability of the battery safety. Energy demand for batteries satellite car that big, but the energy density is not as good as satellite. A small satellite technology of the battery to do support, car batteries, a lot of problems over time. Shanghai Aerospace sector has recently concluded a strategic agreement with SAIC, in 2012 vehicles lithium-ion BATCL50L batteries will be able to industrialization. In August this year, has developed a prototype.

It is reported that the newly developed lithium-ion batteries, the weight and size is a nickel-hydride batteries, metal 1 / 3 of life up to 10 years, weight solve vehicles and fuel cell issues of life. Heritage has always been the safety of style, space technology, lithium car battery technology ion monitoring safe and reliable control system monitors the battery throughout the charging process and discharge to ensure that sufficient, however, but released. Control of conduct also shows the battery power, including energy, temperature, operation status, etc. to solve energy problems for new vehicle VGP-BPS9A/B battery safety.

The current lithium-ion battery car more suitable for urban driving. Jiang Xin-hua introduction of pure lithium-ion battery car has not yet reached the fuel flow of cars, more than 300 volts on a single charge can run 160 kilometers, the fastest 120 km / h, suitable for car urban. However, lithium-ion battery car fuel less expensive than energy consumption. Jiang Xin-Hua worked on an account, the charge to open 18 units of electricity can be 160 km, 100 km takes about 10 units of electricity during the night would probably only cost 3 yuan more than money, cars and fuel as well as 100 km, is estimated to spend more than 70 yuan Qian, lithium-ion battery of the automotive market space should not be overlooked.

With lithium-ion battery market car with a number of urban areas also need a dedicated vehicle charging stations. Currently, the type of car pricing method, there are two slow-filling may be ordinary housekeeping power, full of can be used 6 to 8 hours fast charge to the dedicated fast charging stations need 10 minutes filled with half the power, then industrialization also requires a fast-charging stations to improve the subsidy system. In the parking lot with a group of specialized care facilities for new energy vehicles to provide greater convenience.

About the battery charge acceptance

1 Introduction

Acceptance of battery charging for Dell Inspiron B120 battery performance is a significant indicator of battery charge on behalf of its intuitive performance standards high and low, but the introduction of the internal battery and traction batteries last bike power, which do not charge acceptance capacity requirements can be found in practice for the VRLA battery to charge voltage limiting mode, and traction system, working environment deep cycle, the level of charge acceptance for the battery capacity and cycle life, a film more important as.

Battery charge acceptance ability to limit testing in different conditions, ranging from its mean it is. Under specified conditions, such as processing 1Ah active substance, how much current is transformed Ah, that is to say that although the capacity of the battery charge acceptance, but rather should be “under provisions in charging acceptance “most people are used to load acceptance capacity specified in the provisions of the environment, the value of a constant amount of time to detect the load value of loop current that the size of the charge acceptance, of course, is also a charge acceptance of representation but in the VRLA hp F4486B battery charging system, the ability to accept more good presentation.

Because the battery to a different depth of discharge, charge temperature, current limit depressed pricing to accept different in some laboratory tests very good battery, but unable to stand the test of the relevant market loader is to load because different settings, leading to huge differences in the dissemination of results. The final product is to penetrate the market, the batteries occupy the market to survive, they must learn to adapt to the living environment in this market. Therefore, the burden of acceptance testing is simulated in any market for electric bicycle charger control, indicated both in the absence of special agreement refers to “the battery at 100% depth of discharge 14.8V constant voltage, current limit is not more than 0.2 C, termination conditions are charging circuit current less than 0.03C, which were filled with the output ratio of the total electricity consumption of total capacity, the capacity charge acceptance. ”

2 The acceptance and the capacity of the life cycle of the association

Under the agreed acceptance load test methods to detect than the sony VGP-BPS2 battery of different formulations and participate in several electric vehicle manufacturers data life cycle of the battery test, the load capacity and acceptance cycle Life has shown the tendency of the three basic types.

With the ability to accept charge, battery capacity and cycle life were increased, indicating acceptance of the VLA capacity of the battery cycle life were directly related to the corresponding. 

3 Acceptance support lifecycle factors influencing

Acceptance of burden and trends of the life cycle of accepting charge of the three categories in terms of volume measured immediately after the expiration of batteries for the qualitative detection and found that three types of failure have a certain pattern .

apple M8403 battery capacity class after the break, the loss of water from the battery positive plate less intact, no obvious grid corrosion, negative sulfate serious, apparently because of poor charge acceptance, resulting cell cycle have failed each time sufficient electricity, lead sulfate has continued to increase, leading to the cathode sulfate severe pressure drop in the polarization of the cathode, so that the battery charge and discharge are not normal, the failure of the battery.

classes battery capacity after the failure, loss of water from the battery is high, positive plate intact, plaque remove some corrosion sulfate significantly negative, the situation is the gradual accumulation of sulfate negative, so the battery negative terminal of the polarization ability to continue to decline, causing the battery to water loss increases gradually, many times in the 6.0 cycle, the capacity is failing.

Class battery capacity and cycle testing of more than 200 Re-cycle all have better performance, loss of water from the Dell Inspiron 6400 battery by about 7%, slightly to the corrosion of plates, negative no obvious signs of sulfation.

Tired of the other three cycles and the results of qualitative tests look, capacity VRLA battery charge acceptance and life cycle right there is a direct actor, poor charge acceptance of lead-acid batteries can not completely charged, the negative electrode plate in dozens of cycles would seriously sulfate battery failure between the imposition of a lack of absorptive capacity to charge batteries in the tens of cycles, we started electricity may not be quite enough, so that the negative plate sulfation build slowly corrosion of the battery positive and negative polarization of water loss has continued to increase at a certain cycles on the battery performance is clearly inadequate, and bands by nature deteriorates rapidly as the official home of a good battery in detecting more than 200 cycles in the overall performance of the battery are good, are dehydration negative plaque status better rarely, and the performance of cells maintained in good condition, no downward trend in major.

Overall, can influence the acceptance of responsibility corrosion cells positive, negative sulfate, water loss of battery charge efficiency and whether or not the power quite properly, the capacity fade sooner or later, and the rate of occurrence of a turning point, and so on, thus affecting the battery capacity and cycle life.

Cell phone lithium battery over-charging approach

You mention it, either because the relationship between buying a Big Nine, large and small Nine Nine cell battery is a model, as are the BST-38. When the boss bought a Big 9 sent a charger is estimated that cottage property or just a little sign, because I have not really seen, and there is no common parts loader. Go home with a moment, I feel pretty good, Dell Inspiron 1150 battery empty, almost more than three hours can be filled. Compared to the previous burden that small nine silent growl Jin (eight hours), this charger is clearly much higher efficiency. So I feel very good.

Result, the problem lies in this very nice top.

Watch the Big 9 Mody electricity, and I put a little touch of the nine panels replaced him, and then use it quickly washed into the nine large panels filled, and must post a small battery is almost used nine released and replaced by a good piece of charge. Then, quickly forgotten to recharge at night when they would be. Pricing of course, no hesitation, and took that fast red. Connect the middle of the night went to bed. Wake up. Time to see the blue light has been completed, and initially intended to overturn the result, too lazy to leave the cover to stand in the morning. Then yesterday night, to help small to 9 per battery, battery change is the piece of board. The results show a small battery-nine volumes of safe, suggesting that the lack of electricity, see the state of only 2% after the battery. Currently, I am a little sad. I forget to recharge? Do not think so continue to consider the red solid cap at the top, showing the burden of red light, I read it I thought, they did not load. (sorry for the four cells are not quite sure) just want to go to sleep, never imagined that after five or six minutes, which suggests that blue light filled, Maybe I know that this is certainly the Dell Inspiron 1100 battery there is a problem. So to win after nine charger with the previous small, taken in the progress of green tips filled - that is, the number of full battery, but the phone can not use up.

According to my understanding of lithium batteries, lithium batteries are generally self-protective function, rarely charge-discharge excessive, but now, this phenomenon seems to have been completed - After much deliberation, I would be placed inside the conductor of the telephone line is there are ways to activate the battery. So the Big Nine in, plug-load line. “Black!” Big Nine automatically stopped and refused to load. Moment of a phantom heart sighs. Fortunately, there is no fee to take a nine short years. (actually the real reason is that nine small phone messages are a lot of great nine are currently facing me as a game), so the evening because it was really late, and stir for a long period without Gao Ding, and is I dare not use that piece of the fast charge to charge a dead battery again.

This morning, a ghost continues to take this piece of rechargeable VGP-BPS10 batteries overmix.

Website for a moment of excessive discharge of lithium batteries to the approach here, but the method does not overload. Indeed, aware of Lithium battery life is very long, but in the excessive discharge through normal use after return to active status after a few, so I think for a moment, since the excessive discharge may be restored, why not over-charging?

Note that the piece of board, regardless of who I spend a couple of times have been maintained at about 3% of electricity (the Big 9 members) must know that the great new, all came to a consumption of small power of nine large, so they are very frequent switching machine If a number of electricity will be consumed, so the 3% of electricity is consumed, it shows that the Dell Inspiron 1300 battery still has power. So, simply put a piece of ghost cells appearing on the Big Nine inside, play with the big 9.

Size of the nine power plays, essentially playing the game, then one day be able to put solar panels are consumed, for a ghost is seen with the use of electricity can be the means crazy for this piece of overcharging return to normal power supply (according to my knowledge in physics, this approach should be feasible). The whole process took about five hours, a ghost has ever been stuck in the game page, if not playing games, there is no exit. During boot, at the prompt once the power is low, see charge of 3%. 13:00, when you are prompted more than once power is low, see the power of 2%. After electricity was View all 2%. Over three hours of the afternoon when the power has created a low-power, or about 2%.

A ghost does not shut down, remove the battery directly. And then re-load, turn, reassuring the phenomenon, and the battery icon prompts full frame, view the power consumption is probably about 91%. Preliminary estimates slightly, depending upon the extent that I played the game, usually consumed at least 10 ~ 15% of electricity, which is, I finally managed to get my panels back to normal.

Xie is really a feeling of days. Therefore, the lithium is still very valuable, and be careful love.

By the way saw a long interview of the lithium battery term means: If you do not use lithium batteries for long term storage, the best discharge to 50%, and probably can be stored for one year. Up to one year, first ~ to ensure that the battery charge and discharge function was normal.
