A power supply system including: a first voltage subsystem including a first battery connected to a load via a relay; a second voltage subsystem including a second battery, the second battery having a lower voltage than the first battery; and a DC/DC converter disposed between the first voltage subsystem and the second voltage subsystem, wherein before switching the relay to be closed, the DC/DC converter is configured to: provide a lower voltage than a voltage of the second battery to the first voltage subsystem; subsequently provide the voltage of the second battery to the first voltage subsystem; and subsequently increase the voltage of the second battery to be equal to a voltage of the first battery and provide the voltage of the second battery to the first voltage subsystem.
