电压控制的装置出现错误可能会导致蓄电池组充电过度，这反过来可能会加速放电，比正常情况更严重。

A fault in the voltage-control mechanism may thus cause a battery to become overcharged, which, in turn, might precipitate a deeper discharge than normal.

此外，给nimh蓄电池组充电是个麻烦的过程，因为随着存储电能总量的增加，必须谨慎减少电压。

Also, charging a NiMH battery is a tricky business because the voltage has to be carefully reduced as the amount of energy being stored increases.
