Overheating problems with BMS in process of discharge
A. The discharge current exceeds the maximum rated discharge current of the protection board which caused the protection board overheated.
B. For them BMS with different charge and discharge port , user may mistakely solder the negative discharge wire to the C- port of the BMS.
D. Part of the hardware protection board is discharged in an overvoltage state, and the charging MOS will not automatically turn on. The protection board with the same port structure for charging and discharging discharges under overvoltage conditions. The discharge current is discharged through the internal diode of the charging MOS. A larger discharge current will cause serious heating. When the battery cell voltage drops to the overvoltage release value after discharging, the charging MOS is turned on and the temperature starts to drop slowly.
E. The charging MOS or the discharging MOS is damaged or the driving voltage is abnormal, which causes serious heating of the charging and discharging MOS.
F. The battery core heats up abnormally, and the high temperature is transmitted to the protection board.
