目前电动汽车分为：混合动力、插点式混合动力、燃料电池、纯电动等多种型式。其中纯电动汽车是电动汽车发展的终极方向，目前我国有如比亚迪秦、荣威550plugin等自主品牌的纯电动车，国际上有如特斯拉等著名品牌的纯电动车。 Electric cars are now divided into hybrid, plug-in hybrid, fuel cell, pure electric, etc. Of pure electric vehicles is the ultimate direction of the electric vehicle development, at present our country is like byd qin, roewe 550 plugin independent brand of pure electric vehicles, like tesla and other famous international brands of pure electric vehicles. 电动汽车对环境影响小，能源利用效率高。早在2000年时，在环境保护和国家石油安全战略的推动下，建设电动汽车社会被提上日程，我国进入了电动汽车社会“科技引导”初期发展阶段。到2010年底，全国共有25个城市加入“十城千辆”节能与新能源汽车示范推广工程，50多家企业的184个车型进入《节能与新能源汽车示范推广应用工程推荐车型目录》，各地示范运行各类电动汽车超过1万辆，示范运行里程超过2亿公里，累计载客90亿人次以上。 Electric cars have little impact on the environment, and energy efficiency is high. Back in 2000, the environmental protection and national oil security strategy, driven by electric car society is on the agenda, our country has entered a electric car society "technology to guide" in the early stages of development. By the end of 2010, a total of 25 cities in China to join the "ten city thousand vehicles" energy saving and new energy vehicle demonstration project, more than 50 enterprises of 184 vehicles in the energy saving and new energy automobile application demonstration engineering recommended models catalog, demonstration run around all kinds of electric vehicles more than 10000 vehicles, demonstration operation of more than 200 million kilometers, accumulative total more than 9 billion passengers. 电动车可以解决日益突出的能源问题，应对能源挑战，同时也能减少污染、保护环境。电动汽车有着广阔的发展前景，电动汽车的发展离不开电动汽车充电桩，电动汽车充电桩类似于加油机，可以对电动汽车进行充电。充电桩已成为充电站或电力公司同电动汽车拥有者之间进行贸易结算的计量器具。 Electric cars can address the growing energy problem, tackle energy challenges, and reduce pollution and protect the environment. Electric cars have broad prospects for development, the development of electric cars leave the electric vehicle charging pile, the electric vehicle charging piles is similar to tankers, can charge the battery for electric vehicles. The charging pile has become a measure of trade settlement between the charging station or the electric car owner. 充电桩的充电型式目前主要分为：直流充电和交流充电两种。但是不管是使用哪种充电型式，最终都是以直流方式对电动汽车的电池进行充电。 The charging type of charging pile is currently divided into two main types: dc charging and ac charging. But either way, it will eventually be powered by a dc electric car.
