If the battery is restarted or activated by PV charging
after the battery temperature drops below the protection
recovery temperature, the protection will be released,
the switch of 12V circuit will be closed, and the BMS will
restore power immediately

If the temperature is lower than the warning temperature
for 10s, a warning will be triggered, a warning message will
be sent out immediately, the heating pad will start
working, and the BMS will request 20A charge current. If
the actual charge current is greater than 25A, the BMS will
need to request lowering the charge current

If the temperature is higher than the warning temperature
for 10s, the warning will be cleared, the heating pad will
stop working, and the BMS will request 105A charge
current. If the actual charge current is greater than 110A,
the BMS will need to request lowering the charge current
