Abstract: An object of the present disclosure is to perform discharge control that suppresses deterioration in power storage performance of a power storage component by taking the state of power supply equipment into consideration. A power supply apparatus comprises: a power storage unit that stores electric charges from an external power supply; a control unit that controls charge and discharge of the power storage unit; a state determination unit that determines the power supply state of the external power supply; and a voltage detection unit that detects the voltage at the power storage unit. The control unit performs first discharge control to lower the voltage at the power storage unit to a smaller second voltage value if a predetermined time elapses since the completion of drive of a drive unit and the state determination unit determines that the power supply state is not a state of restricting power to be supplied.
