摘　　要：In order to improve the charging efficiency of lead acid battery, shorten the charging time and avoid the battery polarization, a new charging method was put forward. Based on the analyzed results of charging characteristic of lead acid battery, a pulse quick charger is designed to adjust the charging current pulse’s amplitude and pulse width automatically stage by stage according to the measured battery voltage and feedback current. Compared with other kinds of quick chargers, it has such characteristics as shorter charging time, higher charging efficiency and lower temperature increasing during the charging process. As a result, the battery polarization is reduced efficiently.为了提高铅酸蓄电池的充电效率 ,缩短充电时间 ,消除蓄电池的极化现象 ,在分析密封式铅酸蓄电池的充电特性的基础上 ,采用脉宽调制技术 ,分阶段改变充电电流的大小 ,根据电压、电流反馈自动控制调节充电脉冲宽度 ,设计了一种快速脉冲充电器 .和以往的快速充电器相比较 ,该冲电器具有充电时间短 ,充电效率高 ,尤其是在充电过程中电池内部的温升降低 。
