In the 63rd annual international motor show in Frankfurt, Germany, on September 17-27. In the global financial crisis, the world economy is just not recover situation, the cars have exhibitors with friendly to environment characteristics of new energy vehicles for the window, as the most outstanding is all kinds of electric cars.
The concept of electric vehicle in early 20 years ago, the people are always looking forward to electric car could come as soon as possible, but when electric cars can enter homes in Frankfurt, auto also see specific date.
Volkswagen company board of directors wally, technology in answering reporters hawking berger inquiry, expected to 20 to 30 years, electric cars can freely on highway, but this period, automotive engineers need to electric car constant improvement. In the auto, many famous auto manufacturers, such as Benz, BMW, mass, etc. Are introduced, the Peugeot Citroen of electric cars, but these are calculated, and the exhibition has not the shape of the car to mass production. The car was calculated and finalize the biggest difference is calculated, can not consider manufacturing cost, not even consider using life, but to finalize the car, cost and life is the key of the two indexes, otherwise the market couldn’t accept.
Current electric car into the market of the influence factors or technology, which is the key of the rechargeable battery performance. According to the automotive expert introduction, now the best rechargeable batteries in high-speed vehicles condition, use a few minutes, the battery will be exhausted, so also insufficient trekking and highway driving. The performance of the best international lithium battery charge weight from 10 per KWH to drive a car kilograms, similar to the micro car, like QQ will need to 20 KWH of power, this makes the corresponding the bulk and weight of rechargeable batteries, automotive extra weight weighed 160 to carry 200 kilos of lithium battery, and this is the convert electric energy is only 2 litres of fuel gas! Some manufacturers introduced its electric car battery can drive a hundred kilometers, in fact this is in urban road, and must be low in electric car ideal work environment, such as temperature cannot too high or too low, vehicles cannot open air conditioning, etc.
Restrict the development of electric vehicle another factor is the cost of rechargeable batteries. Now a 20 KWH cost of lithium battery is about 2 million euros, if the battery to mass production, of course, still can reduce cost of at least 1/3. It is hoped the automobile manufacturers. The battery must be in the current level of performance to improve on three times, the price to reduce 2/3, so that there may be a market competitiveness. Toyota motor corp. In the development of electric automobile aspect, it is the most advanced and use the invention, namely so-called hybrid engine technology with electric motor fuel engines, the volume of rechargeable batteries can be smaller. Is this hybrid engine vehicles driving around 20 kilometers, when, after the rechargeable battery power will deplete. This will fuel, and travel time in the transformation of energy into electricity will part for charging the battery,. Toyota hybrids in the market has sold nearly a million cars, but strictly speaking, it is not 100 percent of the electric car.
And the history of the development of electric vehicle with Japan, but really sold on the market of the electric car is small, at least a few German automobile manufacturers, such as mass, Benz, BMW are no formal sales over a car electric cars. The car company every year in international auto show will launch a new electric car models, but basically is doing publicity. Such as the Frankfurt motor, Mercedes launched 392 kw series power electric car, athletic E audi car company has introduced a series of R8 electric car. The highest The two cars are adopted, the third generation of Hybrid technology is in Hybrid technology Plug, this generation of Hybrid technology battery can already through external socket, and in charge of a journey in the use of electricity, after running out of energy will be converted to fuel engine.
Carmakers is the development of the next target no fuel engines, fully sense of electric cars. Achieve 100% of the electric car key, so far, or the rechargeable battery technology will have greater breakthrough.
