What are the reasons for the high temperature of new energy batteries preventing fast charging?

Here are the specific reasons why the high temperature of new energy batteries prevents fast charging: No charging indicator light: Check if the connection is normal, if the charging terminal is normal, and if the CAN signal is normal. Charging indicator light is normal: If the charging indicator light is normal but there is no charging power, check the distribution box, contactor, pre-charge resistor, etc. Charging interruption: If charging can proceed for a period of time, it indicates that the entire system is operating normally during charging. The abnormal interruption must be due to certain abnormal data affecting the controller's strategy to disconnect the contactor, such as high charging port temperature, high battery temperature, abnormal water pump circulation, etc.
