1. An apparatus for controlling charging of an electric vehicle, the apparatus comprising:
a quick charge determination module configured to compare a voltage level of a charging power source supplied from electric vehicle supply equipment (EVSE) with a level of a voltage standard received from a high-voltage battery provided in the electric vehicle to determine whether to directly supply or boost supply of the charging power source;
an inverter configured to boost the voltage of the charging power source supplied from the electric vehicle supply equipment to a specified level or more and provide the boosted voltage to the high-voltage battery when the voltage level of the charging power source supplied for quick charging is less than the voltage standard;
a driving motor provided with a stator three-phase coil receiving the charging power source from the electric vehicle supply equipment; and
a protection mode control module configured to calculate rotor torque that is generated during charging based on an angle of a rotor provided in the driving motor before the quick charging, and induce the rotor torque to be less than a preset reference torque,
wherein the protection mode control module includes:
a charging preliminary information reception device configured to receive vehicle stop information, the angle of the rotor provided in the driving motor, and an intensity of a charging current of the battery before charging as preliminary information for determining whether to charge;
a protection mode execution determining device configured to compare the rotor torque with the preset reference torque to determine whether to execute a protection mode after calculating the rotor torque expected to occur during the charging based on the angle of the rotor and the intensity of the charging current of the battery; and
a memory configured to pre-calculate and store a magnitude of the reference torque that deteriorates or damages a parking sprag.
