摘要
免维护电池不等于不需要维护。本文介绍了用内阻法测量蓄电池故障的原理及方法,并通过试验得出:根据免维护电池内阻值的变化可预测出机车蓄电池的故障。
Maintenance-free battery is also need maintenance.This paper presents the principle and methods to mon itor battery failure via its internal impedance.And the test proves that the failure of battery on locomotive can be pre dicted with the impedance change.
