整组过压释放-PACK overvoltage release voltage

电池组发生整组过压保护后，当电压回落到整组电压释放值时，保护板打开充电开关。此值一般为电池串数*单体过压释放电压。

After PACK overvoltage protection occurs in the battery pack, when the voltage falls back to the PACK overvoltage release value, the BMS turns on the charging switch. This value is generally (the number of battery cell )* (single cell overvoltage release voltage).
