蓄电池组的连接方式与可靠性

The connecting method and reliability of VRLA batteries

同型号阀控式密封铅蓄电池并联运行时，荷电态不同的电池虽然初始充放电电流值不同，但电池之间会自动弥补，最终电流趋于一致，没有发现恶性循环现象。根据上述事实和可靠性工程原理，可以认为采用先并后串的方式组成蓄电池组，对延长电池使用寿命和提高蓄电池组的可靠度是有利的。

It is well known that when the same type VRLA batteries are operated at a paralleling condition,some cells of them in different state of charge might have differmt current values in initial charge and dis-chage, but they could be automaically compensated each other and the final values of current would tend to be equal. Based on this fact and the reliability engineering principle, the battery connecting method in paralle-series is favorable for prolonging the service life and improving the reliability of batteries.
