VEHICLE SYSTEM

A vehicle system of the present invention includes: a motor configured to drive a vehicle; a high voltage storage device connected to the motor and configured to supply the motor with power; a fuel cell connected to the high voltage storage device and configured to charge the high voltage storage device; and a low voltage storage device connected to the fuel cell. The vehicle system includes: a bidirectional first voltage converter interposed between the fuel cell and the high voltage storage device, and configured to adjust a voltage at either of the fuel cell or the high voltage storage device and to supply power to the other; and a second voltage converter interposed between the fuel cell and the low voltage storage device, and configured to adjust a voltage at the low voltage storage device and to apply the adjusted voltage to the fuel cell. The vehicle system is characterized in that the vehicle system includes a bidirectional third voltage converter interposed between the high voltage storage device and the low voltage storage device, and configured to adjust a voltage at either of the high voltage storage device or the low voltage storage device and to supply power to the other.
