整组欠压保护释放电压-PACK undervoltage protection release voltage

当电池组发生整组欠压保护后，当电池组恢复到释放电压时，保护板重新打开放电开关，电池组此时可以正常放电

After the PACK occur PACK undervoltage protection, when the battery pack returns to the release voltage, the BMS reopens the discharge switch, and the battery pack can be discharged normally.
