digital batteries

Increasingly pressing problem of climate change, the ability to Copenhagen for control of the temperature rise in 2 ℃ target relates to the serious problem of human existence. It is generally expected, and Costa will be the focus of the participating countries will focus on specific commitments to reduce emissions, analysts believe it will contribute directly to the new energy industry of the Laptop battery and the development of green lighting.

New Energy Battery Industry: program benefits new energy vehicle development

According to media development and reform of the Commission motor team leader Wang Shulin, has revealed “new energy program for vehicle development was presented to the Council of State should officially promulgated in March 2010. In addition, State agencies will also be launched next year, development of new energy vehicles for the five accompanying measures. Analysts estimate that the new energy industry of the battery will most benefit from the concept of new energy vehicles.

The new energy vehicles in March next year, introduced the planning or

If the concept of energy market news, sauteed, in policy came good constantly. Held recently in Nanchang, the new energy vehicles and lithium-ion batteries feature forums, the National Development and Reform Commission automobile team leader Wang Shu-lin said that China will soon release of new energy vehicles, specifications techniques, and new energy vehicle development presented by Development and Reform Commission of the State Council, was officially promulgated in March next year.

Industry analyst with CITIC Securities automotive Cheng believes that this concept for some companies, the new toshiba PA3191U-2BRS battery energy as Shanshangufen, Jiangsu Guotai other battery manufacturers to make more, but for the entire automotive sector in particular, SAIC, FAW and other great little effect on car companies. Energy vehicles would be the automotive industry and its upstream segment of the cell concept of society have an impact. March release, “the restructuring of the auto industry and the revitalization plan” submitted in 2011 to form a production capacity of 500,000 short-term goal, which is currently more than 1300 million units for the production of the automotive industry is concerned, a very small proportion of new energy vehicles. For their own societies smallest battery to the past, mainly the provision of mobile phones, computers and other battery-quarter production traction batteries, 500,000 will be a huge volume of activity, hence the emergence of new energy concepts will greatly enhance the performance of these companies.

From March 2009 “published by the restructuring of the automotive industry and the revitalization of planning” in response to vehicles with new energy into the electric car, Development and Reform Commission has been clearly put forward in 2011 to form a production capacity of 500,000 short-term goal. It is understood that electric vehicles, power batteries, electric motors, power electronics, the cost of key components, which represents the cost of BATBL50L6 electric vehicles by 30% -50%. Based on the calculation of 500,000 electric vehicles with a value of annual production expected to reach 1,000 billion yuan.

Previously, the two countries issued a joint statement in Beijing, the two sides agreed during the next five years, Sino-US Joint Research Center of the investment for clean energy at least 150 million U.S. dollars the priority research topics will own cars. The market believes that Sino-US Joint Declaration on cooperation in energy sources such as news, digital, relatively rare in history, new energy vehicles are expected to form a positive plate material.

The State Council Development Research Center of Industrial Economics Research Department, Feng Fei energy experts believe that both parties should take the initiative in the field of electric vehicles for cooperation, Chinese electric vehicle is a huge market and cost advantage manufacturing, but the overall level of automotive, industrial technology, the infrastructure was not enough, the United States, it is precisely in this area has a great advantage if both parties take the initiative in the field of electric vehicles to launch a new type of automotive products, will become a reality.

Automotive Li-ion batteries to double next year transfers

As environment-friendly vehicles worldwide are sought, the hybrid electric cars and sells the coming years, the automotive market lithium will develop rapidly. Fuji Institute of Economic Research said that from the 2010 car market lithium batteries will quickly recover and continue to grow. The report predicts that by 2014, manufacturers of batteries that the overall amount of total shipments in 2008 increased by 45.2% to 6.2392 billion yen. Among them, rechargeable apple A1022 battery market will be extended to 4.9983 billion yen, an increase of 66.8%. It should be noted that the needs of the automotive industry will become the main engine of expansion of the battery market is expected in 2009 shipments of lithium batteries automotive sector will amount to ¥ 10,400,000,000 in 2008, based on double ¥ 25000000000; In 2014, the market size will expand rapidly to 2.25 billion yen, or about 215 times in 2008.

Management Consulting International firm Roland Berger Strategy on the global outlook for new energy vehicles in the last research report predicts that by parts of the electric power in 2020, China is the drive assembly and components market worth 10 billion euros Chao, whose 2011, 2014 and 2017 the market value of 600 million euros, respectively, 2.4 billion and 56 billion euros, the estimated market value of the environment in 2020 will reach 6.5 billion euros, even a conservative estimate will reach 2.4 billion euros. According to forecasts the next 10 years, Chinese enterprises in the hybrid and electric vehicles future developments in the field have an advantage, in particular, the basic components, including developments in the field of battery has a great potential because Chinese companies have the advantage of cost of raw materials, manufacturing equipment and labor cost advantage.

According to Roland Berger predicts that 2020 will be the main markets in Western Europe, electric vehicles and plug-in hybrids will be more than 3 million in annual sales, China ranked second to reach 1.58 million of units.

With the plug-in hybrid electric vehicles of all relevant factors, the Roland Berger predicts that by 2020, elements of the VGP-BPL10 battery of the global market share in the largest share of the market size of EUR 9,600,000,000 — 297 between. Now that the Chinese suppliers and Japan, South Korea, North America, Europe, the supplier has a significant cost advantage compared to, the future of the standard battery of quality, durability and differences prices will become increasingly small.

Roland Berger estimates that the demand for battery electric vehicles will be the future of lithium the main source of output growth is expected for 2020, there will be eye-catching 70% of average annual compound rate of growth. Despite the significant growth in demand, but because of higher reserves, experts do not believe that the production of lithium will be a shortage, but there may be a price increase in the risk of a temporary existence.

Promising varieties of independent innovation of automotive batteries

Shenyin analyst Wang said that under optimistic about new energy policies to promote investment opportunities in the automotive battery industry, promising varieties of independent innovation of automotive batteries. Shenyin the next 3-5 years, Ni-MH batteries, HEVs will remain the mainstream of new energy vehicles, HEVs will PH EV, EV co-existence about 10 years. In 3-5 years later, with iron to increase the performance of lithium phosphate to lower costs, and the national network of charging stations in place progressive lithium iron phosphate as the main engine PH of the EV, EV mark the beginning of a broad development prospects. Recommended Keli far Shanshangufen, Jiangsu Guotai, Tibet mining.

Shenyin should grant political future, and the rate of localization is likely to hook. In the development strategy, pending the countries new energy vehicles as an opportunity to catch up from behind their own technology. I believe Sino-US cooperation, China will continue to insist on independent R & D path. Possible future introduction of new energy standards car allowance, spare parts and the main rate of localization will be linked to, and encourage the autonomy of key parts as soon as possible and depending on the location of raw materials. At the same time the state will improve the access threshold, and rigorous review system products.

Shenyin should follow the state ministries and commissions, will be introduced to encourage large-scale electrical vehicles and the development of specific incentive policies. The industrialization of new energy vehicles, including the most important policy for consumers to buy new energy vehicles are subsidized, and the development of new VGP-BPS13A/B energy vehicles and infrastructure planning. The introduction of these two policies that will address bottlenecks in the consumption and use of the bottleneck.

With the popularity of high frequency switching power supply, valve lead acid batteries have been widely used in the power system. Because of its completely sealed, no need to add water to maintain previously known as “maintenance free” battery. That maintenance “free” is a misleading term, which allows the user to relax on the valve regulated lead daily maintenance of battery acid and management, which reduces Laptop battery capacity and lesions early due to lack of battery capacity, or failure in substations and power generation plant accidents were frequent. Therefore, the proper use and care dimensional lead-acid battery VRLA battery to increase their service life is of great importance.

Affecting a major valve battery life

The normal life valve lead acid batteries for over 10 years, in theory, may be 20 years but in actual use often insufficient capacity, failure or early phenomenon. Affect the life of valve lead acid batteries of many factors, including:

1, the ambient temperature

The battery at 25 ℃ environment, availability of a longer life. Temperature, the battery will exacerbate corrosion of the plates at the same time will consume more water, thus reducing battery life, long term operating temperature if higher than 10 ℃, life is about halfway. Valve lead-acid IBM ThinkPad R51 battery changes in capacity with changes in temperature, 25 ℃ when the battery has a capacity of 100% at above 25 ℃, 10 ℃ for each increase in battery capacity would be halved .

Must be careful to do according to actual temperature changes to streamline construction lead-discharge battery acid present, while a battery compartment of the right to control the temperature kept at 22 ℃ ~ 25 ℃ or less.

2 overload

The long-term overload state, the cathode due to the reaction of oxygen evolution, the water is consumed, H + increase, which increases the acidity and near the cathode, the grid corrosion accelerated, causing thinning of the accelerated corrosion of the grid battery, battery capacity reduced, the same time due to water loss intensified, would have drained the danger of the Dell Inspiron 1501 battery, affecting the battery life.

3, an excessive discharge of

Excessive battery discharge occurred mainly in the AC power outage, the battery time to load. When the battery runs down its on-voltage is too low or zero, this will lead to a large number of sulfuric acid inside the battery lead is adsorbed on the surface of the cathode of battery, resulting in the cathode Battery “sulfate.” Lead sulphate is an insulator, its formation is related to the battery charge and discharge performance, have a tremendous negative impact, and therefore the formation of sulphate in the cathode, the higher the greater the internal resistance of batteries, the battery charge and discharge performance, the worse the shorter the lifespan of the battery.

4, the conditions of low discharge current, the impact of

In the discharge current small formed under the particle size of lead sulfate as the conditions of the large discharge current, the size requirements of mainstream higher than the rate of formation of crystals smaller than current conditions, slow the growth of crystals too late to be oxidized very rapidly reduced, and thus a relatively smaller size, whereas in conditions of low current, a crystal of lead sulfate great can be easily restored. Such that crystals of lead sulfate is not a long-term cleanup, will certainly affect the hp 338794-001 battery capacity and longevity. Therefore, the actual expense of the current battery capacity must be executed under a precise calculation.

5, the unbalanced nature of the impact of charge-discharge

The study results showed: composition of the grid alloy and structure in different parts of the distribution is different, leading to the unbalanced nature of the electrochemical properties grid [2], the imbalance is to turn in the float and the load condition of discharge voltage are different, and will be in charge and discharge cycle, so that this difference is increasing and training the so-called “rear battery (battery failure).” The current domestic standards in a group of toshiba PA3191U-2BRS battery float voltage difference between the largest to be ≤ 50mV, the norm in developed countries are ≤ 20mV, should pay attention to the battery and reduce floating state operating voltage differences.

6, thermal runaway phenomenon

As the use of depleted fluid valve regulated lead acid battery design, the infusion of battery electrolyte are adsorbed on the fiber glass, when the load current increases, it is necessary to leave the gas valve, which causes the loss of farm water resistance by significant volume reduction of the charge and discharge large amounts of heat generated in the process, which propagate the heat that the temperature has been taken too late, they will form a thermal runaway. Thermal runaway causes are not promptly reduced float voltage, lax safety valve or pressure valve is open too low, etc. In severe cases of thermal runaway if the landfill has the potential DIP apple A1008 battery voltage transient and Sustainable Housing battery temperature rose to 70 ℃ ~ 80 ℃, and therefore thermal runaway must be a high level of attention.

7, long-term impact of floating charge

Float charging status of battery in the long term, pricing and not the discharge is required to cause passivation of the anode of the battery flat, so that the battery internal resistance increases, the capacity is severely reduced, resulting a shortened life of the battery.

Second, improve the life of valve lead acid battery of measures

With this purpose the life valve lead-acid batteries of factor analysis to improve the life of valve lead acid batteries, we must do:

1 battery of stringent quality levels. In selecting the battery and the process of procurement, we must fully understand the production process manufacturer, manufacturing process and quality control, as well as specifications and so on, if necessary, require manufacturers to conduct the first in the capacity of experiments to screen a difference smaller IBM ThinkPad T40 battery.

A reasonable choice charger. Since the food was monitored over real time and intelligent management capabilities, allowing the battery sealed in the best condition always work, so use high quality switching power supply as a charging unit. High frequency switching power supply system, adopting modular design, when a module is a failure, should be able to immediately withdraw from the race does not affect the normal operation of other modules, module parts should be able AutoFill that batteries are not due to failures caused by excessive discharge module.
