Answer：
1)Charging high temperature protection and recovery When the battery temperature is higher than the charging high temperature protection value and the duration reaches the charging high temperature protection delay, the system enters the charging high temperature protection state and turns off the charging MOS When the battery temperature drops below the charging high temperature recovery value, the charging high temperature protection state is lifted.
2)Discharge high temperature protection and recovery When the battery temperature is higher than the discharge high temperature protection value and the duration reaches the discharge high temperature protection delay, the system enters the discharge high temperature protection state and shuts down the discharge MOS When the battery temperature drops below the discharge high temperature recovery value, the discharge high temperature protection state is lifted.
3)Charging low temperature protection and recovery During charging, when the battery temperature is below the charging low temperature protection value and the duration reaches the charging low temperature protection delay, the system enters the charging low temperature protection state and turns off the charging MOS. when the battery temperature rises above the charging low temperature recovery value, the charging low temperature protection state is lifted.
4)Discharge low temperature protection and recovery During discharge, when the battery temperature is below the discharge low temperature protection value and the duration reaches the discharge low temperature protection delay, the system enters the discharge low temperature protection state and shuts down the discharge MOS. when the battery temperature rises above the charge low temperature recovery value, the discharge low temperature protection state is lifted.
5)MOS high temperature protection and recovery The system has a MOS temperature detection port, when the MOS temperature is higher than the MOS temperature protection value, and the duration reaches the MOS temperature protection delay, the system enters the MOS high temperature protection state and shuts down the charging and discharging MOS When the MOS temperature drops below the MOS temperature recovery value, the system releases the MOS high temperature protection state.
