Claim 0:
1. A charging control method for an electric vehicle that boosts a charging voltage by using a motor and an inverter, the charging control method comprising:
determining, by a deterioration determiner, whether a current imbalance control is normally operated based on currents input from the motor to three-phase inputs of the inverter during charging;
determining, by the deterioration determiner, whether a current sensor is deteriorated based on a result of an internal temperature sensing of the inverter when the current imbalance control is in a normal operation; and
adjusting, by a sensor scale optimizer, a scale of the current sensor to maintain the charging, when a deterioration of the current sensor is detected.
