Gas filling device, gas filling system, gas filling method and moving device

A gas filling system configured to supply a gas from a gas filling device to a moving device,

• the gas filling system comprising the moving device and the gas filling device,
• the moving device comprising:
• a plurality of tanks configured to store the supplied gas;
• separate gas filler passages connected with the plurality of tanks;
• and
• valves provided in the separate gas filler passages, wherein
• the gas filling device comprises a gas supplier configured to supply the gas to the gas filler passages,
• at least one of the moving device and the gas filling device comprises a controller configured to separately open and close each of the valves, so as to control a gas flow supplied from the gas supplier to corresponding one of the gas filler passages, wherein
• the controller comprises:
• a heat dissipation information acquirer configured to obtain heat dissipation information regarding heat dissipation capacity of each of the plurality of tanks;
• and
• an in-tank information acquirer configured to obtain information regarding at least one of temperature and pressure in each of the plurality of tanks, and
• the controller causes opening and closing of the valves to sequentially fill the gas into the plurality of tanks and, after gas filling into the plurality of tanks, to allow communication between the separate gas filler passages, based on the heat dissipation information obtained by the heat dissipation information acquirer and the information in the tank obtained by the in-tank information acquirer.

A gas filling method of filling a gas through separate gas filler passages to a plurality of tanks provided to store the gas,

• the gas filling method comprising:
• (a) obtaining heat dissipation information regarding heat dissipation capacity of each of the plurality of tanks;
• (b) separately opening and closing each of valves provided in the respective gas filler passages, so as to control a gas flow supplied from the gas supplier;
• (c) obtaining information regarding at least one of temperature and pressure in each of the plurality of tanks;
• and
• (d) opening and closing each of the valves to sequentially fill the gas into the plurality of tanks and, after gas filling into the plurality of tanks, to allow communication between the separate gas filler passages, based on the heat dissipation information obtained by the step (a) and the information in the tank obtained by the step c).

A moving device, comprising:

• a plurality of tanks provided to store a gas supplied;
• a plurality of sensors, each being configured to measure at least one of gas temperature and gas pressure in each of the plurality of tanks;
• separate gas filler passages connected with the plurality of tanks;
• valves provided in the separate gas filler passages;
• and
• a controller configured to separately open and close each of the valves, so as to control a gas flow supplied from a gas supplier, wherein
• the controller comprises:
• a heat dissipation information acquirer configured to obtain heat dissipation information regarding heat dissipation capacity of each of the plurality of tanks;
• and
• an in-tank information acquirer configured to obtain information regarding at least one of temperature and pressure in each of the plurality of tanks, and
• the controller causes opening and closing of the valves to sequentially fill the gas into the plurality of tanks and, after gas filling into the plurality of tanks, to allow communication between the separate gas filler passages, based on the heat dissipation information obtained by the heat dissipation information acquirer and the information in the tank obtained by the in-tank information acquirer.
