电动车优缺点为题目的论文

国家现在在推动新能源电动车，对于新能源电动车的企业也有大量的补助，对于购买新能源汽车也有大量的补贴优惠。所以会有越来越多的人选择新能源电动车。未来家用车可能会代替燃油车，如果是货车的话，新能源电动车还是没有办法代替燃油货车。

纯电动汽车：电动汽车的优点1、环保：电动汽车采用动力电池组及电机驱动动力，它工作时不会产生的废气，不排尾气污染，可以说几乎是“零污染”。2、低噪音：电动汽车不会像传动汽车那样发出噪音，它所产生的噪音几乎可以忽略不计。3、经济：电动汽车使用成本低廉，只有汽油车的五分之一左右。而且能量转换效率高，同时可回收制动、下坡时的能量。4、易保养：电动汽车采用电动机及电池驱动，比如：更换机油、滤芯、皮带等。电动汽车只需定期检查电机电池等组件即可。5、政策优：摇号中签率高，免征购置税等政策上的优势较为明显。纯电动汽车：电动汽车的缺点1、续航里程短：一般国内的纯电动汽车的续航里程多为150公里左右，再加上天气、路况、电池等方面因素，实际的续航能力也就100公里出头。开车出门之前需要好好规划路线，这点确实比较麻烦。就以最常见的北汽E150EV电动车为例，厂家标定的续航里程为150公里，经过实际体验，它平均的续航里程在120公里左右，如果使用低于电池容量的20%，那么对电池的使用寿命影响还是很大的。就连京郊一日游都无法满足我们，那么买了电动车就代表你基本上告别自驾游或远途出行了。

缺点：距离偏短。电动自行车的适合使用距离是30公里半径之内（因为要考虑往返），路途太远，不适合电动车，电动车的承载力明显小于小排量摩托车，车架单薄，制动力弱，安全性极低，不适应强度较高的驾驶。

优点：能做到零排放，不污染大气。同样行走100公里的路程，汽车一般要5-15公升的汽油，摩托车也要2-6升的油，但电动自行车只要费1-3度电左右。在世界性的能源危机日益加剧的情况下，电动自行车就是一种非常理智的选择。

电动车注意事项

绝对不能让电瓶长期处于电量不足的状态，并且要养成每天晚上为电瓶充电的良好习惯。长期不用，应该充满电，放置阴凉干燥处，并定期充电（一般10天）。

电动自行车刚起动时，要用脚踏（无脚踏的可以用脚推地面的方式）帮助起动，上坡时候，用脚踏帮助电动车上坡，以免放电电流过大而损坏电瓶。

an economically developed coastal cities, in this beautiful city life in the sky was 20 years. The witness to the scene of the historic moment, but in the harmony of the city, there was a scene not in harmony, the electric prevailed. Electric cars a drilling motor vehicles with non-motor vehicle of the legal gaps in the new product, the electric vehicle of that time there is indeed the Chinese People' s daily on the move brought some facilities. However, things cannot be just one, because everything has two aspects. We would say electric cars the advantages and disadvantages, and only through the only revealed a number of very serious problem. First, let us say electric cars to the people of the benefits. 1, section to environmental protection, and faster than other than motor vehicles soon, and low cost without a licence, driving easily, both young and old suitable "four points mentioned above is electric bicycle in the minds of most people recognized advantage. Now let us look at electric cars the defects and what other places, electric battery should not be permanent, cell damage, replacement rate is high, but battery recovery in the country is still relatively low, this does not fully comply with section to environmental protection concepts, and speed is indeed a bicycle faster than the motor vehicle slow
