在城市地面交通运输中由于电动车在降低城市污染,减少石油消耗,节约能源上有极大的优越性正引起人们广泛注意,成为当前科技开发的重要课题。但在解决它的推广应用上遇到的重大问题是现有的蓄电池都不理想,致使它难于和现在的汽车性能相抗衡。什么样的蓄电池才满足电动车的要求呢?要求是多方面的,具体说来应能满足以下几条。(1)蓄电池的单位重量的能量W·h/kg和单位重量的功率W/kg要高比能量高能使电动车的续驶里程延长,现在大多数研制的电动车的续驶里程
In the urban ground transportation, electric vehicles are attracting widespread attention due to the reduction of urban pollution, reduction of oil consumption and energy conservation. Therefore, it has become an important issue in current scientific and technological development. However, in solving its popularization and application of the major problems encountered in existing batteries are not ideal, making it difficult to compete with the current car performance. What kind of battery to meet the requirements of electric cars? Requirements are many, specifically should be able to meet the following few. (1) The energy per unit weight of the battery W · h / kg and unit weight of power W / kg To high energy than the energy to extend the driving range of electric vehicles, and now most of the development of electric vehicles driving range
