当美国通用汽车公司在90年代中期推出常规铅酸汽车动力电池的最新研究成果时,电动汽车的效率也许将会有所提高。但是,即使通用汽车公司认为这种能源能够对以汽油为动力源的汽车产生极大的冲击,汽车制造商们还是认为铅酸电池不是解决电动车辆动力源的长久之计。加利福尼亚州已经对通用汽车公司和其它汽车制造厂家提出,到1998年,这些厂家生产出的汽车中必须要有2％的车辆没有任何排放物,以此来激励这些公司开发出实用的电动汽车。目前,摆在汽车制造工业前面的主要问题是,如何来改进目前所用的电池。因为相对其重量来说,这种电池储存的能量太少,几个小
When the United States General Motors Corporation introduced the latest research results of conventional lead-acid automotive power batteries in the mid-1990s, the efficiency of electric vehicles may increase. However, even if General Motors believes that such energy can have a great impact on gasoline-powered vehicles, automakers still believe that lead-acid batteries are not a long-term solution to the problem of power sources for electric vehicles. California has already proposed to General Motors and other car manufacturers that by 1998, 2% of the vehicles produced by these manufacturers must have no emissions, in order to motivate these companies to develop practical electric vehicles. At present, the main issue facing the automobile manufacturing industry is how to improve the current battery. Because of its relative weight, this kind of battery stores too little energy, a few small
