    Abstract: PROBLEM TO BE SOLVED: To provide a remaining gas amount calculation device capable of calculating a remaining gas amount in a gas container without using a gas pressure measurement device directly measuring the pressure inside the gas container.
    SOLUTION: The remaining gas amount calculation device A comprises: a hydrogen tank 31; an opening and closing valve 31a for delivering a hydrogen gas into the hydrogen tank 31; a decompression valve 33 configured to depressurize the hydrogen gas delivered out of the gas container 31, a pressure sensor 52 configured to measure a pressure of the hydrogen gas depressurized by the decompression valve 33; and a power supply system controller 50, which calculates a remaining gas amount in the hydrogen tank 31 by calculating the pressure of the gas in the hydrogen tank 31 based on the pressure of the hydrogen gas measured by the pressure sensor 52. Then, the relation of the pressure of a primary chamber 33a to that of the secondary chamber 33b in the decompression valve 33 is made to become a simple relation in such a manner that as the pressure of the primary chamber 33a increases, that of the secondary chamber 33b increases too, and that as the pressure of the primary chamber 33a decreases, that of the secondary chamber 33b decreases.

    解决方案:剩余气体量计算装置A包括:氢罐31; 用于将氢气输送到氢罐31的开闭阀31a; 减压阀33,其构造为对从气体容器31输出的氢气进行减压;压力传感器52,被配置为测量由减压阀33减压的氢气的压力; 以及电源系统控制器50,其通过基于由压力传感器52测量的氢气的压力计算氢罐31中的气体的压力来计算氢罐31中的剩余气体量。然后,关系 使主室33a的压力与减压阀33中的二次室33b的压力成为简单的关系,使得随着主室33a的压力增加,二次室33b的压力也增加 并且当主室33a的压力减小时,次级室33b的压力降低。 版权所有(C)2009,JPO&INPIT
