【正文】 一方面涌現(xiàn)出了數(shù)以千計(jì)的生產(chǎn)廠家，卻又缺乏強(qiáng)勢品牌和技術(shù)創(chuàng)新 。燃料電池具有高效無污染的特性，不同于其他蓄電池，其不需要充電，只要外部不斷地供給燃料，就能連續(xù)穩(wěn)定地發(fā)電。 汽車 的近代 發(fā)展概況 汽車是現(xiàn)代人必不可少的交通工具。s safety, and greatly reduce automobile in collision of drivers and passengers in the buffer, to protect the safety of life. The second chapter electric cars on the environment influence and electronic technology: 1, reduce pollution: of course battery electric vehicle is the key, the electric car battery mainly has: the use of leadacid batteries, nickel cadmium battery, the battery, sodium sulfide sodium sulfide lithium battery, the battery, the battery, the flywheel 3 zinc air fuel cell and solar battery, the battery. In many kind of cells, the fuel cell is by far the most want to solve the problem of energy shortage car. Fuel cells have high pollution characteristics, different from other battery, the battery, need not only external constantly supply of fuel and electricity can continuously steadily. Fuel cell vehicles (FCEV) can be matched with the car engine performance and fuel economy and emission in the aspects of superior internalbustion vehicles. 2, Intelligent electronic technology functions Intelligent electronic technology in the bus to promote safe driving and that the other functions. The realization of automatic driving through various sensors. Except some smart cars equipped with multiple outside sensors can fully perception of information and traffic facilities and to judge whether the vehicles and drivers in danger, has the independent pathfinding, navigation, avoid bump, no parking fees etc. Function. Effectively improve the safe transport of manipulation, reduce the pilot fatigue, improve passenger fort. Third, Electric vehicle development prospect Electric vehicles have a development prospect: Along with the puter and electronic product constantly upgrading electric car, open class in mature technology and perfected, that drive more safe, convenient and flexible, fortable. Now, the electric car from ordinary consumers distance is still very far away, only a few people in bandwagon. Electric cars with traditional to pete in the market, the car Will was electric cars and intelligent car replaced. This is the question that day after timing will e. ABS, GPS, and various new 4WD 4WS, electronic products and the moder
