电动汽车系统构成及原理

Structure and Principle of the Electric Car System

电动汽车以其"零排放"、"零污染"引起了世界汽车行业的高度关注。电动汽车的新电源有钠硫电池、锂电池、镍镉电池等;驱动电动机是电动汽车的心脏,它将电能转化为车轮的动能。相对传统内燃机汽车,电动汽车可省掉离合器、倒车档位、差速器等重要部件,结构更紧凑、操作更简化。

Electric vehicles,with its ＂zero emissions＂,＂zero pollution＂ has attracted the attention of the world.New power source of electric vehicles includes sodium-sulfur cell,lithium battery,nickel-cadmium cell and so on.The driving motor is the heart of electric vehicles,which turns electric energy into wheels＇ kinetic energy.Compared with Traditional internal combustion engine vehicles,electric vehicles save important parts such as clutch,Reverse gear,differential device,compacting the structure and simplifying the operation.
