Abstract
A charging control method for an electric vehicle is configured to boost a charging voltage by using a motor and an inverter, and includes steps of determining 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 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 a scale of the current sensor to maintain the charging, when a deterioration of the current sensor is detected, as a result of the determination.
