Claim 10:
11. A charging control apparatus for an electric vehicle that boosts a charging voltage by using a motor and an inverter, the charging control apparatus comprising:
a sensing device configured to sense an internal temperature of the inverter and currents input from the motor to three-phase inputs of the inverter;
a deterioration determiner configured to determine whether a current imbalance control is normally operated based on a current sensing result by a current sensor of the sensing device during charging, and to determine whether the current sensor is deteriorated based on the temperature sensing result when the current imbalance control is in a normal operation; and
a sensor scale optimizer configured to adjust a scale of the current sensor when a deterioration of the current sensor is detected.
