A device for controlling a charging of a hydrogen tank for a vehicle, may efficiently perform a charging of a hydrogen tank regardless of a hydrogen charging protocol for each charging station configured to supply hydrogen to the hydrogen tank by directly controlling a hydrogen charging speed of the hydrogen tank in a vehicle upon charging the hydrogen tank mounted in the vehicle.

A motor vehicle with a pressure vessel system includes at least a first pressure vessel arranged in a first region of the motor vehicle and at least one second pressure vessel arranged in a second region of the motor vehicle having a lower intrusion probability than the first region. Fuel is preferentially removed first primarily from the at least one first pressure vessel. When the lower limit of fuel level or fuel temperature is reached in the at least one first pressure vessel, fuel is removed from the at least one second pressure vessel. If the fuel supply rate from the at least one first pressure vessel is lower than an overall fuel supply rate for an energy converter, fuel is removed from the at least one second pressure vessel to meet the overall fuel supply rate needed by the energy converter.

Fueling verification systems and methods for corroboration of vehicle fueling are described herein. The systems and methods provide for verifiable transmission of data collected from a remote source to assure data integrity and maintain proper fuel transmission as part of vehicle fueling. The systems and methods can include collecting a first fuel measure for a fueling process from a delivery source. A second fuel measure can be recorded into a blockchain. The second fuel measure for the fueling process can be received from a recipient source. Then, the first fuel measure and the second fuel measure can be correlated to determine a fueling offset. Then, the delivery source and/or the recipient source can be compensated based on the fueling offset.

Provided are a method and apparatus for calculating a volume of a compressed gas storage vessel, a computer, and a medium. According to the method, three test vessels with known volume and initial pressure are used to establish a pressure equilibrium with a compressed gas storage system, and pressure values in three equilibrium states are respectively detected. In this way, according to the three pressure values and the known volumes and initial pressures, a volume of the compressed gas storage system, a volume of a hose, and a pressure value of the compressed gas storage system in an initial state can be quickly and accurately calculated. By accurately obtaining the volume of the compressed gas storage system, the volume of the hose, and the pressure value of the compressed gas storage system in the initial state, a refueling rate can be increased as much as possible while ensuring safe refueling.
