在环保意识日益增强的今天,开发节能、无污染的绿色型电动汽车,是各国汽车生产厂家最为关注的课题之一。这些汽车由高性能蓄电池向发动机提供动力,从而代替了内燃机的动力装置,以往的变速箱也成了电控系统。虽然目前生产的电动汽车在动力和行驶里程方面还未达到理想目标,但是,这些技术正在得到迅速发展。各国科研人员正全力以赴地开发一系列提高电动汽车及动力电池的性能的高新技术。电动汽车新技术的开发据美国塞拉咨询公司的一份报告显示,在电动汽车开发中,最初几年内所花费用多于正常汽车费用2.1万美元,改进一辆车需要花费5000美元,但随着规模经济的形成,这种额外费用将会迅速下降。报告还估计,如果生产30万辆电动汽车的话,其费用成本与 In today’s ever-increasing awareness of environmental protection, the development of energy-saving, pollution-free green-type electric vehicles, car manufacturers in all countries are most concerned about one of the topics. These cars powered by high-performance batteries to replace the internal combustion engine power plant, the transmission has become the past, the electronic control system. Although the current production of electric vehicles in power and mileage has not yet reached the desired goal, however, these technologies are rapidly developing. National researchers are working hard to develop a series of high-tech to improve the performance of electric vehicles and battery. Development of new electric vehicle technology According to a report from Serra Consultants in the United States, during the first few years of electric vehicle development, it cost more than $ 21,000 for a normal car and $ 5,000 for a car, The formation of economies of scale, this additional costs will decline rapidly. The report also estimated that if the production of 300,000 electric vehicles, the cost and cost
