Document Type and Number:
Japanese Patent JP6784243
Kind Code:
B2
Abstract:
To prevent power consumption caused by communication with a hydrogen charging device, in a fuel battery vehicle having a hydrogen tank.SOLUTION: A fuel battery vehicle comprises a hydrogen tank, a hydrogen charging port, a hydrogen introduction pipe, a charging port side check valve, a transmitter, a pressure sensor and a controller. The pressure sensor measures pressure between the hydrogen charging port of the hydrogen introduction pipe and the charging port side check valve. The transmitter transmits a value of the pressure which is measured by the pressure sensor to the hydrogen charging device. When the measured pressure goes below prescribed threshold pressure while the transmitter transmits the measured pressure, the controller stops the transmission of the measured pressure by the transmitter. Immediately after a finish of the supply of a hydrogen gas, the fuel battery vehicle finishes the transmission of pressure data, and power consumption caused by wasteful transmission can be thereby suppressed.SELECTED DRAWING: Figure 2
