Abstract
Provided is a power supply control device for controlling power supply to a motor installed in a vehicle, including: a switching element configured to turn on and off the power supply to the motor; a current detection circuit configured to detect a current flowing to the motor; and a control unit configured to determine whether or not the motor is in a locked state based on the current detected by the current detection circuit, and control turning on and off the power supply to the motor at a duty cycle that corresponds to the current detected by the current detection circuit, if it is determined that the motor is in the locked state.
