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.

Abstract: According to one aspect of the present invention, a method for diagnosing failure in a pressure gauge of a hydrogen filling system includes filling a fuel cell vehicle powered by hydrogen fuel with the hydrogen fuel from an accumulator, in which the hydrogen fuel is accumulated, via a dispenser; and acquiring pressure values measured by a plurality of pressure gauges disposed at different positions in a flow passage of the hydrogen fuel between the accumulator and an outlet of the dispenser at timing when a flow rate of the hydrogen fuel to be filled at a stage close to an end of the filling becomes a threshold value or less, determining whether or not a deviation between the pressure values is within a threshold value on the basis of acquired pressure values, and outputting a determination result.

Abstract: An information processing device includes one or more memories and one or more processors. The one or more processors are configured to input information regarding an atom of a substance to a first model; and obtain information regarding the substance from the first model. The first model is a model which includes: layers from an input layer up to a predetermined layer of a second model to which information regarding atoms is input and which outputs at least one of a value of an energy or a value of a force; and another layer, and which is trained to output the information regarding the substance.
