PROBLEM TO BE SOLVED: To provide a power supply system for making a movable body into a movable state by using electric power of a starting power storage device mounted in the movable body more efficiently.SOLUTION: A power supply system 100 according to an embodiment of the present invention is the power supply system 100 mounted in a hybrid vehicle, and includes: a high voltage battery 21 supplying electric power to an electric motor 20; an auxiliary battery 23; a first high voltage relay 26 arranged between the electric motor 20 and the high voltage battery 21; and a power supply ECU 1 controlling the first high voltage relay 26. The power supply ECU 1 makes the first high voltage relay 26 conductive by the electric power supplied from the high voltage battery 21 when determining that the first high voltage relay 26 is non-conductive if the first high voltage relay 26 is to be made conductive using the electric power supplied from the auxiliary battery 23. |
