digital batteries

In the new energy vehicle development in countries and regions around the world have been based on their assessment of different options, research the appropriate technology and Laptop battery development and to encourage support for taking a different strategy. In the current situation as a whole, Japan and the United States and Europe has focused on lithium batteries and fuel cells, but our country to take into account the resources and the maturity of technologies, the accent newly released policies on the promotion of nickel-hydride batteries in metal.

Ni-MH battery to become the object of political support China’s current

In our letter of the Department of June 25, the “new energy automotive manufacturing companies and the rules of access management products,” the vehicle, according to new energy vehicles, systems and key deadlines assembly technology, the degree of IBM ThinkPad R51 battery perfection of the national and industry standards, and industrial degree of difference will be divided into initial phase where the development period, three different stages of maturity of the technology and give Management classified.

According to state regulators, the home-products only in the production of small volumes, and only in approved areas, scope, duration and conditions of model runs, and the operational status of all products for real-time monitoring, product development phase allows the mass production only the approved area, scope, duration and conditions of sale, use, and at least 20% of sales of products running in the real-time monitoring, mature products and conventional products for the Dell Inspiron 1300 battery automobile, “the automakers and ad management product even in the sale and use of the same products with conventional automotive .

This means that in China, December 31, 2010, equipped with lithium batteries and hybrid electric vehicles will be limited to the sale and use areas, use nickel-metal hydride battery and hybrid electric vehicles can be sold and used across the country.

Experts believe that the reason why countries are now central to the development of lithium nickel-hydride batteries, metal, the main reason is that the nickel-hydride technology of metals of the hp PB992A battery is more mature than the Lithium, the most abundant mineral resources, the future of new energy vehicles will track better access to the advertising phase.

“Ni-MH – Lithium-Ion battery – fuel cell,” Industrialization Path

In the three commonly used types of car batteries, batteries lead acid to cause serious pollution of the environment has long been out of the consumer applications, nickel-metal hydride batteries, although the marketing of the integrating the moment, but key indicators of laboratory data were lower than lithium batteries, and the theory Basically, there is no room for; lithium despite superior performance, but still can not be guaranteed safety and the relatively high costs have also affected its business.

Experts predict that the new energy vehicles will be in the “Ni-MH – Lithium-Ion sony VGP-BPS5 battery- fuel cell” industry-oriented development path. From the trend of development and rates, and short-term performance can be achieved only with nickel-hydrogen batteries, nickel-hydride technology of metal drums since the most mature in the next three years, will remain the mainstream new energy vehicles, followed by nickel-hydride technology of metals of the lithium and iron phosphate, hydrogen fuel cells, one third of the world, 5-lithium year and will gradually replaced by fuel cells. Battery giant Panasonic and Sanyo also found that lithium-ion battery can be replaced within 2 ~ 3 years, nickel-hydrogen batteries, mainly due to cheaper nickel-safe hydrogen batteries, has reached high production wide. Lithium batteries also need to continue to research topics such as security, so take time business.

According to economic analysis of Japan Fuji mainstream nickel-metal hydride batteries will be able to continue until 2011, but after 2011, Li-ion toshiba PA3465U-1BRS battery will gradually erode the market share of nickel-hydride batteries, metal The agency predicted in 2009 car-use nickel-metal hydride rechargeable batteries in the world market size than the previous year by 23.7% to ¥ 92,000,000,000, but the 2015 Ni-MH rechargeable battery-vehicle market will be reduced to ¥ 55,000,000,000.

Market demand for nickel-hydrogen batteries to save 2-3 years of rapid growth in

Nickel-technology hydrogen fuel cell, and the industry chain to determine their maturity will be a period of time with the coexistence of lithium batteries, lithium iron phosphate cathode material for lithium batteries allows the emergence of performance and cost advantage has been achieved, but stable, production capacity and lack of effective management of the lack of apple A1175 battery testing continues to be a part of the new energy discourage automobile manufacturers, however, batteries nickel Hydrogen-crossed many years of fighting, technical and industrial chains are quite perfect, in a short period of time can form a stable vehicle support capabilities, and therefore can still be a period of time in vehicles new energy and widely applicable.

According to industry estimates, the market for nickel-hydrogen cell is still expected to get 2-3 years of rapid growth over the next 2-3 years, “10 City 1000″ program, the growing popularity of hybrid cars and export markets overseas for nickel and other factors make hydrogen market demand from the Aspire 3000 battery to strong growth, and when the nickel-hydride batteries, metal and batteries Lithium is still Nanfenbozhong when the nickel-hydrogen batteries will usher in a short period of rapid growth.

Among them, China has launched a “10 City, 1000″ How to get the first batch of nickel demand hydrogen battery market. It is estimated that in “10 City, 1000″ program, about 3200-4000 vehicles, new energy vehicles (including buses and cars) using Chinese-made nickel-hydrogen batteries in three years , bringing a total of about 3.5-4.4 one million kilowatts-hour nickel-hydrogen , VGP-BPS2C needs.

Together, both domestic demand and exports weakened in 2012 after the nickel-hydrogen batteries are gradually replaced by lithium batteries.

Maintaining the pace of R & D policy

In the production of automotive Dell U4873 battery business in China with a production capacity of nickel-hydrogen batteries have represented the majority of companies, including Chunlan Group, Ke-Li Yuan, the Torch High Technology, Hunan Shenzhou share Kane etc., which Chunlan Group is the nickel-metal hydride HEV battery power technology, leading market shares in a leading position in the Torch High Technology and Hunan Shenzhou possessed a certain amount of technical base and position market.

As for the lithium battery, most domestic manufacturers are not capable of mass production, but the planning of the corresponding production has been implemented, it is expected after 2010 are capable of mass production .

Experts believe that technological advances, prices for cars in China and business related to the IBM ThinkPad X60 battery in addition to promoting the industrialization of nickel-hydride batteries, metal, more attention should be some of long term, to devote resources to research and lithium battery development, and maintaining fuel cell monitoring techniques to fill a broader energy market new car is ready.

Lithium-ion battery in 2-3 years, although difficult to replace the nickel-hydrogen batteries, however, not to ignore is the future of lithium batteries replace nickel-hydride batteries in the metal abreast of new energy vehicles. From a global viewpoint, Japan is the international motor current energy news and research cell power and application of more advanced countries, Japan has big businesses in automotive and HSTNN-LB31 battery has invested in building lithium-ion power line battery production, concentrated in the 2010-2011 production. Fuji economy as lithium-ion battery will begin in 2011 to gradually replace nickel-hydride batteries, metal, lithium-ion battery, as no doubt the future of consumer technology path.

Today, Japan In addition to switch focus on lithium batteries, the Japanese cars in the development of new energy and use, particularly in the development of fuel cell vehicles and promotion, many faster than expected China’s internal. Some years ago the Japanese economy, Trade and Industry on development of vehicle fuel cell law and the promotion of a calendar, its strategic objectives are as follows: In 2010, the Japanese used vehicles fuel cell to reach 50000; in 2020 to 5 million; 2030, year to universal access to cars to fuel cell.

Our country is technically in electric vehicle what the bottlenecks, which reached the international advanced level?

Ren Chang: It is a very professional issues, electric vehicles are two to five plan years of scientific research and national technology, we first control the electric vehicles of certain technologies, it should say who made considerable progress, we are now above the global integration technology has almost reached the international advanced level, but this can not be close, has not been reached. Our Laptop battery with overseas there is a big difference. The engine, our products, technology and foreign countries there are still gaps.

So now the basis of our industry as a whole should be said that, preliminarily to industrialization may do some demonstrations, demonstration of applications, but also can not enter the commercialization phase. It’s a real electric cars in society, in people’s homes there is very, very long distances.

Reporter: You said that the electric car is a pure electric vehicle, or all of it?

Ren Chang: I speak mostly very pure electric technology, fuel technology is ahead of the technology, Tongji University, the team did a great job, we must say we are in an advanced international level. But now the level of IBM ThinkPad R51 battery electric vehicle technology, fuel price and use it is still a long way from reality. Fuel technology is the high technology end, the electric fuel car is the ultimate goal, but at present we can only do a little cutting-edge technological development.

Let me give a simple example. Hybrid, it is the leading product in the world, more importantly, gain full access to the commercial scene is the production was massive, and the user can use as an ordinary car, as is our goal to pursue, but we are currently countries have not yet reached a level where pure electric vehicle.

Reporter: battery technology is mentioned bottlenecks do?

Ren Chang: First of all is the battery, the gap between us and abroad, also has a large lithium battery is the main direction, but still in early development stage, the level of scale and Abroad there are still significant gaps, particularly in the industrial fuel density, reliability, and we are now able to ensure a cycle of 1000, representing 3 million km, but we at least reach 10 thousand kilometers. In addition, the Dell Inspiron 1525 battery price is too expensive, and domestic about 3 yuan / W, 1 kW to 3 thousand dollars, 20 kW to 60,000 yuan, and now 40-Watt engine may also be necessary for millions of yuan, but can guarantee reliability.

In such circumstances, countries have also issued many preferential policies. However, the preferential policy does not mean that the car had been able to produce, and now this policy is mainly directed against the movement of vehicles to transport work to be subsidized. In this sense, the public transport policy in support of state subsidies to make some demos, and no commercial transaction. Purchased for future use can not afford too poor to feed themselves, but the infrastructure is not complete, they have limited its development.

Reporter: How can we reduce the gap with foreign countries do?

Ren Chang: the gap between us and foreign countries is the main level of technological backwardness. Firstly, to strengthen scientific research, we also conducted a number of times the group of experts from our research is enough investment capital related to R & D, but also and mainly rely on Ministry of Science and allocate special funds to support a number of projects to do. In addition to the government’s foreign policy orientations supportive, companies are also given, and even joint development of business alliances. Therefore, we must first increase the scientific and technological research and development, investment capital increase. Followed by industrial-scale industry of electric cars and the automotive industry both traditional relationships are different, the most important difference is that different from the entire energy sector, industry electric vehicles, including the hp F4809A battery industry, the automotive industry. The automotive industry is not where the engine manufacturer can be installed in the car engine has a lot of specificity, we now have many electrical installations are small businesses, large enterprises disdain and small businesses in the power technology is far enough, entry is also far from sufficient, conditions for production in various fields deviation is very large, relatively speaking, it is also a factor.

Then, attach importance to the country will gradually foster emerging industries, increase investment in these technologies support, including venture capital, now encourages the industry to support innovative, energy-related news industry of automotive parts, it is very important. Why fire the new energy sector, because many people are optimistic about this direction. The next step is to direct more state funds in addition to the new energy industry, in batteries, motors, electrical systems, etc. should be increased.

Meanwhile, the defense community is also important to promote community awareness of environmental protection, to accept the electric cars. Concept of China and consumption abroad not the same. Pure electric vehicles, especially sony VGP-BPS5 battery electric vehicles are the basic maneuvers from the beginning, the Chinese consumer habits may be very different.

Small cars, chinese compared to cars and other state enterprises, technology, energy is not sufficient, the reliability is not good, can not be a great support, but the cost is very high. The small car is the direction of development of electric vehicles, whether China should have its own means.

Reporter: The strength of some domestic cars are not as Toyota, Honda, etc, and now that the Alliance Electric Car from China, which is a good way?

Ren Chang: I must say that our country after years of experience, and now developed to the Industry Alliance. For example, Chongqing Science and Technology system, which was introduced in innovative alliance of electric cars formed at the same time led by Chongqing Changan Electric Vehicle Industry Alliance, the two alliances that rely on corporate contributions do enough to rely on each enterprise union together.

We are of technical innovation and the Alliance, in an alliance where we share resources with each other, and proposed communication system to build the same platform, or understanding of their needs through exchange of the other may increase the level of toshiba PA3285U-2BRS battery research and development can be faster and better development, this can be received in a small, but there are fairly good results.

Industry Alliance can work with the support of each plant collaborative development. I can give Chang’an supply batteries to determine the development plan of Chang’an, will the kind of consumer technology, so it will produce 100 thousand, 20 million units so they can spend , so that synergies can be formed into an industrial base more quickly support our OEMs, so that our suppliers to make better products.

I personally think that the combination of technology or Industry Alliance is our next major release of the production and research on technology R & D model, which would greatly advance our technological innovation.

Reporter: vehicles with new energy in many areas, the future development of new energy vehicles exactly what the process, who feel this way?

Ren Chang: should say, these are the countries were very concerned about how secure our online technical state of electric vehicles in the general group of experts held a series of seminars, the state ministries and commissions also organized a special research policy. With national conditions of China and experience in the development of large countries, we now determine the apple A1185 battery electric car is the transformation of the automobile industry of China, the leading direction, which is a lot of ‘Technical Analysis.

I think this is the right choice, but because of pure electric vehicle-related technologies can meet market demand, so there is still a long way to go, and each stage has a choice, we have to do transition program, so that if it is done well can be energy efficient, but also to reduce emissions.

When the BTP-43D1 battery technology has improved continuously, the cost of falling into the business model of using the larger, thus completing the transition to a pure electric. At one stage may be a direction that is primarily based on our first hybrid may be the main May to 20 years, 30 years later is a pure electric vehicle based. Currently, a more realistic option is a hybrid.

Reporter: There are three kinds of hybrids, we mixed in the mixing of light technology in the international community should be at the top, re-mixed with a large gap between Mody?

Ren Chang: Light mixed with more mature, less the same level with foreign countries, but it is a vehicle early electrical products, strictly speaking, is not truly representative of the actual development of electric vehicles at the future.

Make now a part of the mix and made some achievements, but there are still gaps and abroad. Re-level mixture of products that we are a big difference, and why? Because the automotive industry in China has a very important engine of our technology base is not in our hands of the Chinese people themselves, although many own brand products, technology control engine is a technology engine control is mainly for foreign help to do so, we pay for the Dell RN873 battery technology they produce, the central part of the alien. Therefore, lack of basic technological research led us to re-mixed when the subject of considerable technical limitations. Because he wants to integrate the engine as a whole, we can not make changes to the engine, can not do the depth of integration can not do much optimization can make a few simple integration, If our technical level and a lot of gap. This is an important contradiction of state assets abroad, the brand has these advantages, we chose this advantage over foreign countries, choose the re-mixed with foreign countries that we do not have d ‘ benefits, if we split the maturity of someone else built our maturity, it may be is a more appropriate choice.

We pure electric vehicles as China’s transformation of the main direction of choice is the reason, since there was no more than others, we have taken this step, focus on developing pure electric vehicles at the top to make a transition.

Reporter: hybrid is far more than the shorter form?

Ren Chang: It depends on the maturity and marketing cell HSTNN-LB31 battery technology at what time to meet. The longer the hybrid is more. I think this line is relatively long, later years, perhaps 10 or 20 that large volumes of hybrids on the market. Initially, we considered a motor vehicle internal combustion traditional 40 years, 50 years of depletion of energy resources, but I still constantly find new oil fields, it is also a direction, threatening the supply of ‘energy transmission system is also very important.

Pure electric vehicles and vehicle fuel Laptop battery in the car using the process to achieve zero emissions, and can completely get rid of dependence on oil resources, development of new energy vehicles will be the ultimate goal, and choice the route of transition, due to cars alternative energy and health energy vehicles more dependent on physical energy associated with the development of regional characteristics, it is difficult in the global promotion, hybrid vehicles because improvement of the current automotive technology is relatively small, in the period of high oil prices have a better fuel economy and meet the emission standards high, the transition is the best way.

Companies in the Japanese automotive industry to seize the lead

Hybrid cars work, you can use two types of mode of mechanical and electrical drive, for example, a plug-in hybrid technology makes the process more convenient pricing is the tendency of development of hybrid cars.

From the worldwide sales of hybrid electric vehicle distribution point of view, the United States is the largest sales of hybrid electric vehicle market in 2007, sales of 35 million units, representing 70% of sales Global, Japan, Britain and Canada, IBM ThinkPad R40 battery market shares, respectively 13.8%, 3.2% and 3%, while other countries, only 10% of the total share of the market to be developed more.

In the hybrid car in the United States, the largest consumer data, the Japanese auto companies, with its field of hybrid cars first advantage engine, has occupied the market. Market for hybrid cars from Toyota stood out, its 2007 revenues to U.S. $ 18 million, occupying 79% market share, Honda, Ford, GM and Nissan’s share of 10.2%, respectively, 7.1%, 1.5% and 2.4%.

Global sales reached one million of best-selling Toyota Prius in 2006, landing in China after the sale had been poor in sales volume in 2008 should remain Dell Inspiron 700m battery in the 1000 shows that the average current consumption of China Vehicle hybrid does not endorse the purchase of desire is low, the Chinese market will be developed.

Cost advantages of high-priced car

Compared with conventional cars, hybrid cars use the cost advantage is a prerequisite for development. Under current conditions, the use of hybrid cars benefit costs reflect the price of $ 20 or more cars, hybrid technology in the price of 5 million cars do not use cost advantages, even if we could reach 100% of the fuel economy effects, the use of cost – is still 22% higher than conventional vehicles, in the price of 100,000 yuan and 15 million motor vehicles, only 80% or more of the effect of fuel economy, only a small hp OmniBook XE3 battery cost advantage, in the price of 20 million yuan, 250,000 yuan and 30 million vehicles to achieve 40% -60% of fuel economy effects reflecting the use of certain cost advantages, indicating that hybrid technology has real value.

In essence, the cost advantages of hybrid vehicles is the cost of electricity compared to the cost of the benefit of oil. 93 # If the price of petrol has dropped 30 percent, or 4.46 yuan per liter, while the use of hybrid technology, cost advantage will be smaller, the sony VGP-BPS5 battery actual value, if 93 # Price Gasoline rose 30 percent, or 8.28 yuan per liter, then the mixture power technology will be most obvious practical value.

Technological progress is the development of hybrid cars, a powerful, if technological advances and determine the price of electricity decreased by 30%, its hybrid technology to enhance the role of cost-competitive with gasoline prices increasing 30 per cent have a significant impact.

Optimistic circumstances, the application of hybrid toshiba PA3399U-2BRS battery technology has broad prospects. 93 # If the price of gasoline rose 30% and 30% decrease electric drives simultaneously, then the application of the value of hybrid technology is very obvious price of 10 million yuan for the use of car have some cost advantages.

About the development of battery technology

The current hybrid cars use nickel-hydride technology battery metals major, but the nickel-metal hydride batteries have a number of technical performances, close to the theoretical limit, such as energy density, charge and the rate of firing. The lithium apple PowerBook G4 15 inch battery has an energy density, high capacity, no memory, etc., are car manufacturers and battery suppliers unanimous approval of the need to solve the problem today lies in its use of stability, security and cost of production.

Lithium iron phosphate is a lithium battery and high safety, high stability, high specific capacity, protection of the environment and the benefits of cheap, but its poor conductivity, is the need to address major problems. BYD Auto’s dual core technology of the vehicle mode is “AND-Power”, the use of technology in the lithium iron phosphate is, each battery voltage 3.3 V, 60 Ah, up to 2000 times the number of charge cycles and, especially, Zambia Di F6DM vehicle for living to 100 of the TravelMate 290 battery up to 430 km distance, 100 km in electric mode, the hybrid model of 330 kilometers, but actual production is still some time.

Compared was applied to the hybrid plug-in hybrid technology allows hybrid vehicles with better performance and ease of use. General Motors designed the Chevrolet Volt is to use technology lithium, PHEV, should be available in 2009, while the Toyota Prius is not due to technical problems the new technology of lithium used in cars. Volt lithium Dell HD438 battery on board is produced by the A123, the ability of 16kWh, the current Prius battery capacity 12 times, greatly improving the endurance capacity of hybrid vehicles, but “may be plug – in “design to allow for battery recharging more convenient, 110V under load of the interface can be filled with 6 hours.

In order to rapidly develop high performance, low power cost of the vehicle battery, the major automakers and battery manufacturers have adopted a cooperative approach to development, triggering a LCBTP03003 battery powering the vehicle for International Development in the world. General Motors moves in which the most active at the same time with the A123, Compact Power, Cobasys, and Saft four companies to cooperate, to seize the leading position in battery technology lithium, the intent is obvious.
