摘　　要：对航天用氢镍蓄电池的几种主要充电方式进行了介绍和分析。在此基础上形成了P-T(压力-温度)曲线充电控制方法,并对其具体实现方案进行了介绍,最后通过试验证明该方法是合理、可行的。该充电控制方法引入蓄电池温度信号,对蓄电池压力进行补偿,可以更为精确地控制蓄电池的容量,同时通过较小的充电电流间歇性充电代替以往工程型号中通常使用的固定小电流长期涓流补充充电,避免了由于涓流设置不合理可能出现的过充或欠充。Several charging control technologies for nickel-hydrogen battery in spacecraft were researched in this paper.And on this basis,a new charging control technology of the P-T（pressure-temperature） curve was introduced.The test results show that the technology is reasonably and practicable.The temperature signal T was introduced to compensate pressure P of the battery which could more accurately control the capacity of the battery.A small charge current was intermittently used instead of a fixed long-time charge current widely used before,which could avoid the overcharge or undercharge of the battery due to the unreasonable setting of the trickle charge.
