Abstract

A display portion of a meter device of a fuel cell vehicle has a motor output meter and a capacitor capacitometer. The motor output meter has an output indicating portion and a regenerative power indicating portion. The output indicating portion indicates an output by the power of the fuel cell and an output by the power of the capacitor in different colors. The regenerative power indicating portion indicates a regenerative power of the motor in a different color from that indicated on the output indicating portion. The capacitor capacitometer indicates an amount corresponding to a power charged to the capacitor the residual capacity of the capacity in different colors.

Claims

1. A display device for a fuel cell vehicle provided with as a power source a generator-motor powered by a fuel cell and a chargeable and dischargeable energy storage, said display device comprising:

an output meter of said generator-motor, wherein the output meter indicates an output of said fuel cell and an output of said energy storage separately in different colors; and

a capacitometer of said energy storage.

2. A display device for a fuel cell vehicle as set forth in claim 1, wherein the capacitometer indicates a regenerative power and a residual capacity of said energy storage separately in different colors.

3. A fuel cell vehicle comprising:

a generator-motor as a power source which is powered by a fuel cell and a chargeable and dischargeable energy storage; and

a display device having an output meter of said generator-motor and a capacitometer of said energy storage, wherein the output meter indicates an output of said fuel cell and an output of storage separately in different colors.

4. A display device for a fuel cell vehicle provided with as a power source a generator-motor powered by a fuel cell and a chargeable and dischargeable energy storage, said display device comprising:

an output meter of said generator-motor; and

a capacitometer of said energy storage, wherein the capacitometer indicates a regenerative power and a residual capacity of said energy storage separately in different colors.

5. A fuel cell vehicle comprising:

a generator-motor as a power source which is powered by a fuel cell and a chargeable and dischargeable energy storage; and

a display device having an output meter of said generator-motor and a capacitometer of said energy storage, wherein the capacitometer indicates a regenerative power and a residual capacity of said energy storage separately in different colors.
