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.

Apparatus and method for controlling charging of electric vehicle

A power conversion system includes an inverter having a three-phase circuit including a plurality of power semiconductor devices and configured to supply driving power to a motor according to an applied torque command, and a controller configured to predict a maximum temperature of the inverter based on an actual measured temperature of any one of the plurality of power semiconductor devices and phase current of the motor, and to actively limit the torque command depending on the predicted maximum temperature of the inverter.
