Patent attributes
A method of inspecting the safety of an electric vehicle charger includes: fastening a charger connector between a charger side and a vehicle side; checking for an abnormality in the charger and the charger connector by checking for a leakage current; raising a voltage of a quick charger to a voltage of a high-voltage battery of a battery unit by closing a high-voltage battery main relay; charging a motor inverter capacitor of an inverter unit connected to the battery unit by closing the high-voltage battery main relay; opening the high-voltage battery main relay and then closing a quick charge relay of a charging unit connected to the inverter unit; checking whether normal charge is enabled by requesting a normal charge voltage and a normal charge electric current from the vehicle side to the charger side; and forcedly discharging a voltage with which the motor inverter capacitor is charged.
