<p><P>PROBLEM TO BE SOLVED: To certainly display "FULL" on a display unit when a tank is continued to be filled with compressed hydrogen until the filling operation is restricted. <P>SOLUTION: The gas remaining capacity display controller 100 includes a mass calculator 112 and a reference value setting units 114, 116. The mass calculator 112 obtains compressed hydrogen pressure P and temperature T which are inside a hydrogen tank 10, calculating the mass of the compressed hydrogen inside the hydrogen tank 10 from the widely-known state equation of a gas. When the tank 10 is continued to be filled with the compressed hydrogen until the filling operation is restricted, the reference value setting unit 114 sets the mass calculated by the mass calculator 112 as a reference value used to allow the display unit 200 to display a compressed gas remaining capacity inside the hydrogen tank 10. An indication controller 116 calculates a rate of the mass to the reference value, allowing the display unit 200 to display the compressed hydrogen remaining capacity inside the hydrogen tank 10 on the display unit 200 from the rate calculated. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
