Title:
HIGH PRESSURE VESSEL SYSTEM AND CONTROL METHOD THEREOF
Document Type and Number:
Japanese Patent JP2021025623
Kind Code:
A
Abstract:
To continue operation without reliability degradation even if anomaly of a pressure sensor is detected.SOLUTION: A plurality of pressure sensors 38 of a high pressure vessel system 10 measure gas pressure in a high pressure vessel 14. A control device 34 includes an anomaly detection unit 78 for detecting anomaly of the pressure sensors 38, a storing unit 80 for storing gas pressure in the high pressure vessel 14 at the time of immediately before anomaly detection as a storing value, an accumulation unit 82 for obtaining an accumulation value by accumulating gas supply amount to a fuel cell 16 after detecting the anomaly, and an estimation unit 84 for calculating gas pressure in the high pressure vessel 14 as an estimation value with the storing value and the accumulation value. The control device 34 monitors gas pressure in the high pressure vessel 14 based on a plurality of pressure measurement values in a normal case, and in an anomaly case, monitors gas pressure in the high pressure vessel 14 based on at least one pressure measurement value and the estimation value.SELECTED DRAWING: Figure 1
