  • Patent number: 11865929
    Abstract: 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.
