(1) When the charger is not connected to the power battery assembly, the charger will be automatically initialized to the conventional control charging mode after self-test (manual, IC card or charger monitoring system operation mode can be selected). When the charger is operated manually, it should have clear operation guidance information.
(2) After the charger is connected to the power battery assembly, the charging information of the power battery assembly is obtained through communication, and it is automatically initialized into the power battery assembly ECU automatic control mode (referred to as the automatic control charging mode).
Charging efficiency and power factor of the charger
When the output voltage of the AC input isolated AC-DC charger is 50%~100% of the rated voltage, and the output current is the rated current, the power factor should be greater than 0.85, and the efficiency should be greater than or equal to 90%. The efficiency of the DC-input non-isolated DC-DC charger is to be determined.
