摘要： An apparatus for controlling charging of an electric vehicle is configured to calculate a rotor torque expected to occur during charging based on an angle of a rotor provided in a driving motor before charging is performed by multiple input voltages, and allow charging to be performed after inducing the rotor torque to be less than a reference torque by moving the electric vehicle a specified distance to correct the rotor angle when the calculated rotor torque is greater than the reference torque so as to avoid deterioration or damage to a parking sprag. As a result, it is possible to prevent the parking sprag from being damaged by the rotor torque generated during charging so as to avoid the occurrence of an accident.

摘要： 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.
