Claim:
1. A power supply system electrically-connected to a system power source, the power supply system comprising: an electric storage device that is configured to be capable of being charged with electric power supplied by the system power source and to be capable of discharging electric power into a loading apparatus, which is capable of operating through use of the electric power supplied by the system power source; a connecting terminal area that is provided to be connected to the system power source at time of the electric connection of the power supply system to the system power source; a main energization line that connects together the connecting terminal area and the electric storage device; a sub-energization line that branches from a branched part, which is provided on the main energization line, to connect together the loading apparatus and the main energization line; a first energization switching unit that switches an energization line of the main energization line, which connects the electric storage device and the loading apparatus, between an energized state and a non-energized state; a second energization switching unit that switches an energization line of the main energization line, which connects together the branched part and the connecting terminal area, between an energized state and a non-energized state, the second energization switching unit is provided separately from the connecting terminal area; a third energization switching unit that switches an energization line of the main energization line, which connects together the second energization switching unit and the connecting terminal area, between an energized state and a non-energized state; a control device that detects switching states of the first energization switching unit, the second energization switching unit and the third energization switching unit and controls their switching operations; and an electric power converter disposed between the second and third energization switching units; wherein the electric storage device, the first energization switching unit, the branched part, the second energization switching unit, the electric power converter, the third energization switching unit and the connecting terminal area are provided in this order along the main energization line.
