US 2021/0278048 A1 · GAS CONTROL SYSTEM AND GAS CONTROL METHOD

Abstract

A gas control system includes a high pressure tank, a temperature sensor, a pressure sensor, an injector, and a gas control ECU. The high pressure tank includes a liner, a reinforcing layer, and a discharge hole for discharging hydrogen gas from the liner. The temperature sensor detects the temperature of the reinforcing layer or the temperature around the outside of the high pressure tank. In the implementation of the gas control method, the gas control ECU, based on temperature information detected by the temperature sensor and pressure information detected by the pressure sensor, changes the timing of starting limiting control for limiting the discharge of hydrogen gas.

Dependent claims

A gas control system, comprising:

a high pressure tank including a liner made of resin and filled with a highly pressurized fluid, a reinforcing layer covering an outer surface of the liner, and a discharge hole configured to discharge the fluid from the liner;
a temperature sensor configured to detect a temperature of the reinforcing layer or a temperature around an outside of the high pressure tank;
a pressure sensor configured to detect a pressure inside the liner;
a flow rate adjustor configured to adjust a flow rate of the fluid discharged from the discharge hole;
and
a control unit including one or more processors and configured to control an operation of the flow rate adjustor,
wherein the one or more processors start limiting control to limit discharge of the fluid, based on temperature information detected by the temperature sensor and pressure information detected by the pressure sensor.
