一、充电电压的选择 通常采用的充电方法有两种,即定电流充电法和定电压充电法。在汽车上对蓄电池充电,是采用定电压充电。 定电压充电的特性和实践证明:充电电压过低,使蓄电池长期处在亏电状态,容易使极板上产生一层较粗大而又坚硬的硫酸铝晶体。这种晶体导电性能极差,会堵塞极板 First, the choice of charging voltage The charging method is usually used in two ways, namely the constant current charging method and constant voltage charging method. In the car on the battery charge, is the use of constant voltage charging. Constant voltage charging characteristics and practice have proved that: the charging voltage is too low, so that the battery in the long-term loss of power, easy to produce a thicker layer on the plate and hard aluminum sulfate crystals. This crystal conductivity is very poor, will plug the plate
