1. A gas filling apparatus comprising:

  • a filling mechanism, including a gas carrying pipe and at least one valve, for carrying a gas from a gas supply source while measuring flow rate of the gas;

    a filling hose connected to the gas carrying pipe and having a filling nozzle at an end of the filling hose;

    an attachment sensor for outputting a detection signal after detecting that the filling nozzle is attached to a filling port of an in-vehicle tank;

    a calculating circuit for, before filling the gas to the in-vehicle tank, calculating time that the pressure in the in-vehicle tank reaches a target pressure based on flow rate of the gas carried by the gas carrying pipe; and

    an informing circuit for, before filling the gas to the in-vehicle tank, transmitting the time that the pressure in the in-vehicle tank reaches the target pressure;

    wherein filling gas to the in-vehicle tank by the filling mechanism becomes possible after the detection signal is inputted to the filling mechanism from the attachment sensor.
