Abstract
To provide a gas filling method in which it is possible to estimate a volume of a tank with high accuracy even when the tank has a small volume. A hydrogen filling system includes a hydrogen station having a pressure accumulator of compressed hydrogen gas, a vehicle having a hydrogen tank, a connection tube system that connects the accumulator and the tank, and a flow rate sensor and a station pressure sensor provided on the connection tube system. A hydrogen gas filling method is a method of filling the tank with the hydrogen gas from the pressure accumulator and includes estimating a volume of the hydrogen tank based on detection values of the flow rate sensor and the station pressure sensor and a volume value of the connection tube system, after a start of filling of the hydrogen tank with the hydrogen gas from the pressure accumulator.
