镍氢电池充电控制技术的探讨

Discussion of charge control technique for MH/Ni battery

镍氢电池充电控制技术是镍氢电池使用维护的重要组成部分。为了充分发挥镍氢电池的效能,文章对国内外各种镍氢电池充电控制技术的性能进行了客观的分析比较,重点就“-ΔV”充电控制技术及实施方法进行了探讨和介绍,并进一步证实了“-ΔV”控制方式的可靠性。

An accurate charge method was develope d based on '- Δ V' technology. The technical features of the charging process o f Ni-MH battery was studied by changing the temperature and initial state of cha rge of the battery. By comparing the characteristics of three possible ways of c harge, by the control accuracy, the easiness of control to avoid the overcharge and the prevention possibility of overheating caused by low charge efficiency, ' - Δ V' control technique was selected as the basis for the development of real battery charger. The control logic was verified.
