Abstract: A control apparatus for an electric vehicle is provided, which is capable of reducing the weight of the electric vehicle and preventing the inverter circuit from overheating. When the vehicle stops on an uphill due to stalling, the control unit 30 starts counting the time over which current is supplied through the same IGBT element. When the count value reaches a value corresponding to the time at which the IGBT 40 starts generating heat, the control unit 30 outputs a control signal to reduce the motor driving current to the IPM 20. The rotation sensor 60 detects the rotational position when the motor rotates in the reverse direction, while the reduction of the motor driving current reduces the driving power of the motor. Based on the detection of the rotational position, the control unit 30 performs switching of the phase of the IGBT 40, and when the normal current supply phase is connected, the motor driving current which drives the motor is increased.
