1、 Battery Starter Charging system Ignition Lighting Auxiliary Electronic Device6.2 Battery The purpose of the battery is to store electrical energy. It does this by converting the electrical energy supplied to it into chemical energy so that when an electrical current is required the energy change is

2、 reversed. 蓄电池用于储存电能，它将电能转变为化学能储存，在用电时再将化学能转变为电能。 In making the battery, several similar plates are properly spaced and welded to form a plate group. Plates of two types are used, one for the positive plate group, the other for the negative plate group. A positive plate is nested with a negative pla

3、te group, with separators placed between the plates to form an element. Separators are designed to hold the plates apart so that they do not touch, and at the same time they must be porous enough to permit electrolyte to circulate between the plates. 在制造蓄电池时，几块相似的极板以适当的间隔焊在一起组成极板组极板组分为两种，阳极板组和阴极板组一块

4、阳极板被一组阴极板所包围，隔板放在两组极板之间形成一个单元隔板又必须具有多孔性，使电解液能够在各极板间流动6.3 Charging System The charging system provides the electrical energy a car needs once its engine starts. The charging system does two jobs. First, it provides electrical power for the ignition system and the cars electrical accessories. Second,

5、it replaces the power used by the battery in starting the car In other words, the charging system maintains the batterys state of charge. 一旦开始发动，充电系统就给汽车提供电能。充电系统有两个任务：首先，给点火系和电力附件提供电能；其次，给电池补充在起步时消耗的电能，换句话说，就是维持电池的电荷状态。6.3.1 Alternator Electricity can be produced by moving a conductor through a magnetic field , The opposite also holds true . By moving the magnetic field and holding the conductor, electricity can be generated in the conductor . This current is called an induced current . This is the basic principle of the alte
