Abstract

An ECU selects a power supply mode which controls a power supply to an inverter apparatus, in a case where a fuel cell vehicle is instructed to start-up by an ignition switch and it is detected that a power supply inlet and a power supply connector are fitted together based on voltage of CONNECT signal, and selects a driving mode which controls the driving of the fuel cell vehicle, in a case where the fuel cell vehicle is instructed to start-up by the ignition switch and it is detected that the power supply inlet and the power supply connector are not fitted together based on voltage of CONNECT signal.

First claim

What is claimed is:

1. An electric vehicle comprising:
a power source;
a drive motor driven by power from the power source;
a switch which is provided inside the electric vehicle and instructs the electric vehicle to start-up;
a power supply inlet which is connected to the power source;
a separate equipment which is provided separately from the electric vehicle and has a power supply connector through which power is supplied from the power source as DC current to an external load as AC current;
a fitting detection device which detects whether the power supply inlet and the power supply connector are fitted together or not; and
a control device,
wherein the control device includes a mode switching device
which, by an instruction by the switch, selects a power supply mode that controls a power supply to the separate equipment, in a case where, when the electric vehicle is instructed to start-up by the switch provided inside the electric vehicle, the fitting detection device detects that the power supply inlet and the power supply connector are fitted together, and
which, by an instruction by the switch, selects a driving mode that controls a driving of the electric vehicle, in a case where, when the electric vehicle is instructed to start-up by the switch provided inside the electric vehicle, the fitting detection device detects that the power supply inlet and the power supply connector are not fitted together.

2. The electric vehicle according to claim 1 , further comprising:
an outward power supply contactor which is capable of cutting off the connection between the power source and the separate equipment, and is provided at the power source side of the separate equipment as viewed from the power source to the external load.

3. The electric vehicle according to claim 1 , further comprising:
a control power supply device which supplies a control power which actuates a power control device which controls a power supply from the power supply connector to the separate equipment.

4. The electric vehicle according to claim 2 , further comprising:
a control power supply device which supplies a control power which actuates a power control device which controls a power supply from the power supply connector to the separate equipment.

5. The electric vehicle according to claim 4 ,
wherein the outward power supply contactor is controlled by the control power supply device.
