镍氢电池在UPS电源上的应用研究

Application Study on Nickel-metal Hydride Battery in Uninterruptible Power System

利用镍氢电池组充电电流大、充电时间短、速度快的特性,制作UPS的辅助控制系统,实现一主一辅,零秒切换,解决频繁长时间停电时,铅酸电池组不能快充的缺陷问题,提高供电的安全性和持续时间,以满足用户的特殊要求。

In the paper,it is introduced the secondary control system of uninterruptible power system（ UPS） is manufactured with nickel- metal hydride battery（ Ni- MH battery） pack since it is with such features as great charging current,short charging period and high speed. One primary and one secondary control systems could make switch within zero seconds to solve the problem that lead- acid cell pack could not charge rapidly when there is frequent long- time power cut so that the security and duration of power supply could be improved to meet special requirements of consumers.
