Claim 8:
9. A method of controlling charging of an electric vehicle, the method comprising:
boosting a voltage of a charging power source to a specified level or higher and supplying the boosted voltage when a voltage level of the charging power source supplied from electric vehicle supply equipment (EVSE) is less than a voltage standard received from a high-voltage battery provided in the electric vehicle, otherwise determining to supply the voltage of the charging power source directly to the high-voltage battery;
receiving vehicle stop information, an angle of a rotor provided in a driving motor, and an intensity of a charging current supplied to the battery as preliminary information for determining whether to charge before charging is performed;
determining whether to execute a protection mode by comparing a rotor torque with preset reference torque after calculating the rotor torque expected to occur during charging based on the angle of the rotor and the intensity of the charging current;
calculating, as a protection distance, a required travel distance of the electric vehicle required to correct the angle of the rotor such that the rotor torque, which is expected to occur during the charging, is reduced to less than the reference torque when it is determined to execute the protection mode; and
displaying a result of a determination to execute the protection mode in the determining of the protection mode execution and the protection distance calculated in the calculating of the protection distance through an audio video navigation (AVN) module so that a driver recognize the result and the protection distance.
