In a charge/discharge control apparatus, a voltage conversion unit performs voltage conversion between a second conductive path and a third conductive path. A first switch switches between an on state where a current is allowed to flow from a first conductive path to the second conductive path and an off state where the current is blocked. A second switch switches between an on state where a current is allowed to flow from the second conductive path to a second power path, and an off state where the current is blocked. An auxiliary charging unit switches between a supply state where power is supplied to a power storage unit via a path different from a path including the voltage conversion unit, based on power supplied via the first conductive path, and a stopped state where the supply of power via the path is stopped.
