摘要： In a control method of a motor drive system, when a first motor corresponding to a first drive wheel is being driven in a second drive mode among a first drive mode in which the first motor is driven by a first inverter of the motor drive system and connected to a first end of each of coils of the first motor and the second drive mode in which the first motor is driven by the first inverter and a second inverter connected to a second end of each of the coils and configured to selectively operate, whether or not the second inverter malfunctions is determined. When the second inverter malfunctions, a drive mode is changed so that the first motor is driven in the first drive mode. An output limit of the first motor in the first drive mode is relaxed.

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.
