为了设计一种新型NiMH电池快速充电器 ,研究了NiMH电池充电过程中的电化学反应以及电池的充电特性 ,确定采用一种新型的快速充电方法———脉冲充放电方法 .并通过实验验证这种方法的可行性和优越性 .试验结果证明充电器加入放电脉冲后充电迅速 ,能够很好地控制电池的充电电压和温度 ,防止损伤电池 ,而且电池最后的容量比没有加入放电脉冲时的容量大 .
In order to design a new type of quick charger for NiMH battery, the new method of pulse charge discharge was adopted after studying the charge process and analyzing the NiMH battery charge characteristics. The charge and discharge experiments were carried out to check feasibility and superiority of the new method. The results indicated that with the discharge pulse added the charger can charge quickly, the battery voltage and temperature can be properly controlled to prevent the battery being destroyed, and the capacity of the NiMH battery is greater than that of the battery without the discharge pulse added.
