简介:一、蓄电池的作用蓄电池其实可以理解为一个电的蓄水池,车辆的启动以及大灯、收音机等设备的用电都要从蓄电池中汲取,而发动机启动后带动的发电机则向蓄电池充电.二、蓄电池的分类蓄电池从使用便利性上分为传统铅酸蓄电池和免维护蓄电池.铅酸蓄电池是由正负极板、隔板、壳体、电解液和接线桩头等组成,其放电的化学反应是依靠正极板活性物质和负极板活性物质在电解液(稀硫酸溶液)的作用下进行的,其中极板的栅架是用铅锑合金制造.传统蓄电池在使用过程中会发生减液现象,这是由于栅架上的锑会污染负极板上的铅,造成水的过度分解,大量氧气和氢气分别从正负极板上逸出,使电解液减少.因此,这里的“维护”,主要是定期检查蓄电池,打开观察口排气,发现缺液及时补充电解液或蒸馏水.
