For example: Three series battery pack application, when the initial, A, B, C three single battery for 100% of capacity, but in the long-term use, the batteries have had uneven, resulting in at some point, A 80% of the remaining battery capacity, B Battery of the remaining 40% of capacity, C battery of the remaining 60% capacity; If Charged the three series pack batterys, due to the protection of high voltage, When A is charged 100% full and let the charger closed , B Battery capacity for only 60%, C for 80% of battery capacity and thus give rise to the battery pack inside the battery B and C is not fully charged.

这些不均衡现象不仅会使电池包容量变小，甚至还可能会造成严重的过充电、过放电等安全隐患。让我们来对这两种情况进行仔细分析：首先是针对电池包容量变小的情况；。以三串电池包应用为例，初始时，A、B、C三单体电池都为100%容量，但在长时间的使用下，各电池产生了不均衡，造成在某一时刻，A电池剩余80%容量，B电池剩余40%容量，C电池剩余60%容量；此时对电池包内进行充电，由于过高压保护的作用，当A电池充满100%而使充电器关闭时，B电池容量才为60%，C电池容量为80%，从而出现电池包内B电池和C电池有未充满电现象。
