A power supply system is installed in a vehicle having an autonomous driving mode. The power supply system includes a first load circuit connected to a first load that operates using electric power from a main battery; a second load circuit connected to a second load that operates using electric power from the main battery or an additional battery and that is necessary to continue the autonomous driving mode; and a first circuit connection/disconnection mechanism provided on a power supply line for electrically connecting the first load and the second load, the first circuit connection/disconnection mechanism that electrically connects or disconnects the first load circuit to or from the second load circuit. The first load circuit is located on an upstream side of the first circuit connection/disconnection mechanism. A current path on a downstream side of the first circuit connection/disconnection mechanism includes a first path for allowing a current flowing from the first load circuit to the first circuit connection/disconnection mechanism to flow from a branch point located on the downstream side of the first circuit connection/disconnection mechanism to the second load, and a second path for allowing the current to flow from the branch point to the additional battery. A current value allowed for conduction through the first path is higher than a current value allowed for conduction through the second path. The second load circuit includes the second load and a third load that is not necessary for traveling in the autonomous driving mode. The third load is connected to the second path between the branch point and the additional battery.
