充电低温保护延时-Charging under temperature protection delay

电池组在充电时，温度达到充电低温保护温度，并且持续达到充电低温保护延时时间，保护板关闭充电开关，停止充电，建议设置为5秒

When the BMS is charging, the temperature reaches the charging under temperature protection temperature, and the charging under temperature protection delay time continues to be reached. The BMS turns off the charging switch and stops charging. It is recommended to set it to 5 seconds.
