Gas filling system, gas filling method, and vehicle

摘要

A gas filling system (1) includes a gas tank (30); a gas filling device (2) that fills gas into the gas tank (30); and a controller (24) that calculates a temperature increase ΔT and a pressure increase ΔP in the gas tank (30) during a predetermined period of time (t seconds) that elapses from a start of gas filling. The controller (24) selects a filling rate map (Ma, Mb) from a prepared filling rate map group on the basis of the calculated temperature increase ΔT and the calculated pressure increase ΔP. The gas filling device (2) carries out gas filling using the filling rate map selected by the controller (24).

主权项

1. A gas filling system, comprising:
a vehicle that includes a gas tank as well as a temperature sensor and a pressure sensor that acquire information about a temperature and a pressure in the gas tank immediately after start of pre-filling as tank initial temperature and tank initial pressure and that acquire information about the temperature and the pressure in the gas tank after a predetermined period of time for pre-filling has elapsed; and a gas filling device that fills gas into the gas tank; the gas filling device comprising: a controller that calculates a temperature increase and a pressure increase in the gas tank during the predetermined period of time for pre-filling that elapses from a start of gas pre-filling based on the tank initial temperature and the tank initial pressure and the acquired tank temperature and tank pressure after the predetermined period of time for pre-filling has elapsed, and that selects a filling rate map from a prepared filling rate map group on the basis of the calculated temperature increase and the calculated pressure increase; and an operation control unit that uses the filling rate map, selected by the controller, to carry out gas main-filling.
