digital batteries

Currently, internal research and development of electric vehicles are mainly used in lithium-ion batteries, but aside from battery production BYD, the majority of mileage endurance and speed are very limited, short duration, while security must be improved, currently, many failure rate of the Laptop battery is greater than one millionth of the level of security, burning vehicles and problems arise. These problems make electric cars the field of large-scale participation of private cars, there are many obstacles, which are common problems encountered in the world by other manufacturers.

Beijing Institute of Technology, an electric car expert said, a very important reason is that production of the 40Y6797 battery has not yet industrialized, there is a lot of batteries or a hand, small production, and therefore difficult to ensure the quality and unity. At the same time, users still have a lot of battery to use inappropriate need for more guidance.

Institute of Electrical Engineering Chinese Academy of Sciences, one expert said that the life of the current mileage is not enough battery electric cars at low speed using the scope is limited. At the same time, although some argue that the majority of electric vehicles can use the family 220V load voltage, but the actual operating point of view, usually filled with a Dell Latitude X1 battery lasts 10 hours or so, so long cooldown is neither convenient nor practical to use for this building Fast Chargers needed.

Charging station is difficult to achieve large-scale construction of

Improved facilities at the loading station of the electric vehicle is the key to the promotion scale. National Grid is currently pricing of infrastructure has accelerated the pace, Zhengzhou and Wuhan, a small number of charging stations and other places have been commissioned, but because of the high cost of station construction load, uniform standards for Jianzhan missing, investors are not clear and the relevant government departments to coordinate the hp F3172A battery large-scale construction makes the charging station in the short term is unrealistic.

“In fact, the current total capacity of electricity generation to meet domestic electricity demand electric vehicles, shortages of electricity does not exist, the key is that the feeding stations many The lack of capacity of storage, a large number of peaks and valleys are the loss of electricity. In addition, coal remains the major current sources of national electricity production, this sony VGP-BPS2 battery is not conducive to environmental protection, the State must increase investment in wind energy and nuclear power. “Beijing University of Technology, an electric car expert said.

In addition, construction of facilities so as to take charge of standards that must be resolved. China Lithium-standard system battery power ion drafting group of a person in charge, how to ensure that the construction of fast-charging toshiba PA3399U-2BRS battery charging station is key to ensuring the charging station can buses, taxis and private cars are able to apply, just as importantly, the technical level, there are some difficulties.

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.
