Abstract

A control circuit controls fillings speeds of hydrogen gas filling a fuel tank. The control circuit a) receives values of a characteristic of the tank during a process of filling the tank with the hydrogen gas, b) calculates at different times during the filling process the differences between a preset threshold of the characteristic of the tank and the values of the characteristic of the tank received at the different times during the filling process, c) calculates plural filling speeds of the hydrogen gas filling the tank during the filling process, each of the filling speeds depending on one of the plurality of differences between the preset threshold and the values of the characteristic of the tank received at the different times during the filling process, and d) controls an operation of a dispenser for filling the tank with the hydrogen gas at the calculated filling speeds.
