摘　　要：基于氢镍电池本身的特性,分析讨论了如何安全高效地管理氢镍电池组的充电过程。同时针对电池过充问题,提出了用旁路电流来实现涓流充电的思想,从而避免了氢镍电池组由于充电管理不当而造成的使用寿命短、利用效率低等问题。实验结果说明:通过旁路电流来实现涓流的方法,能有效地抑制了温度变化对其充电过程的影响。Based on the characteristics of Ni-MH battery,how to manage the charge process of nickel-hydrogen battery pack was analyzed and discussed.In connection with overcharging problem,the trickle-charge was realized with a bypass current,so as to avoid some shortcomings,such as short-life and low-efficiency,which were usually caused by unreasonable management of Ni-MH battery pack.The experiment result shows that using this method to achieve trickle-charge can effectively inhibit the interference of temperature.
