An on-board device for storing pressurized gas, for example hydrogen. The device includes a tank, a sensor for measuring the pressure of the gas in the tank, a first sensor for measuring the ambient temperature, a computer having an electronic system equipped with a microprocessor for acquiring and processing data. In particular, the computer is configured to: i) receive and process measurements from the sensors, and ii) calculate a theoretical minimum temperature and a theoretical maximum temperature of the gas in the tank on the basis of the measurements from the sensors and by using at least one predefined predictive model, the computer also being configured to approximate the temperature of the gas in the tank to a value of between the theoretical minimum temperature and the theoretical maximum temperature, or to a value equal to one of either the theoretical minimum temperature or the theoretical maximum temperature.
An on-board device (100) for storing pressurized gas, comprising a tank (1), a first sensor (4) configured to measure the pressure (Pgas) of the gas in the tank (1), a first sensor (5) configured to measure the ambient temperature (Tamb), a computer (6) comprising an electronic system provided with a microprocessor for acquiring and processing data, the computer (6) being configured to:
A method (200) for real-time estimation of the temperature (Tgas) of a gas in an on-board device (100) for storing pressurized gas, the device (100) comprising a tank (1), a first pressure sensor (4), a first temperature sensor (5), a computer (6) comprising an electronic system equipped with a microprocessor for acquiring and processing data, the method (200) comprising a step (S1) of measuring the pressure (Pgas) of the gas in the tank (1), using the pressure sensor (4), a step (S2) of measuring the ambient temperature (Tamb) outside the tank (1), using the first temperature sensor (5), a step (S3) of determining, on the basis of the measurements from the sensors (4, 5) and by using at least one predefined predictive model, a theoretical minimum temperature (TtankCold) and a theoretical maximum temperature (TtankHot) of the gas in the tank (1), and a step (S4) of approximating the temperature (Tgas) of the gas in the tank (1) to a value comprised between the theoretical minimum temperature (TtankCold) and the theoretical maximum temperature (TtankHot), or to a value equal to one of either the theoretical minimum temperature (TtankCold) or the theoretical maximum temperature (TtankHot), the steps (S3, S4) being executed by the computer (6).
