供电动车使用的化学电源

电动车作为新型的交通工具,受到世界各国的普遍关注。化学电源技术是制约电动车商业化发展的瓶颈。在提出电动车对动力电池的不同要求后,着重分析了电动车用电池的技术现状及优缺点。对比指出各类电池的研制改进方向。重点是提高比能量、比功率、延长循环寿命,以提高电动车辆的动力性及经济性。

Chemical Power Supply Used for Electric Automobile

As a new kind of vehicle, electric automobile has been generally paid attention to in the world. But chemical power supply technique is a choke point obstructing the commercializing development of electric automobile. After stating the dynamic power supply demand needed for electric automobile, the batteries needed for electric automobile were put on analyzing emphatically in this paper: the technical actuality, advantages and disadvantages of lead acid battery, nickel chrome battery, nickel hydrogen battery, lithium ion battery and fuel battery. Though comparing, the researching and improving direction of each kind battery was pointed out. The emphases were increased the ratio of energy and power, extended circulating life, in order to improve the power system and reduce its cost.
