PROBLEM TO BE SOLVED: To provide a power supply system of a vehicle surely executable of save running of the vehicle and the vehicle in a state that cannot secure a cable way to a drive unit from an energy storage device.SOLUTION: A power supply system of a vehicle 100 includes: an energy storage device 110; a charger 200 to convert the voltage of the power from an external power supply 500 and to charge the energy storage device 110, an auxiliary battery 180; and a DC/DC converter 170 that does an interactive voltage conversion between the cable way to supply the power to the drive unit to generate the vehicle driving force from the energy storage device 110 and the auxiliary battery 180. The DC/DC converter 170 is composed to convert the voltage of the power accumulated in the auxiliary battery 180 when the save running to make the vehicle 100 run in a state that cannot secure the cable way. The charger 200, when the save running is performed, is composed to convert the voltage of the power from the energy storage device 110 and charge the auxiliary battery 180. |
