and S101, if the remote data platform receives hydrogenation data sent by the hydrogenation station after the hydrogenation station completes the hydrogenation, determining the hydrogenation amount of the fuel cell vehicle according to the hydrogenation data.
In this embodiment, including communication module in hydrogenation station and the remote data platform, communication module can be the equipment subassembly that has functions such as communication and data processing, can be wiFi module, 2/3/4/5G module, and the hydrogenation station sends the hydrogenation data to the remote data platform after accomplishing this hydrogenation, and this hydrogenation volume of fuel cell vehicle is confirmed to the remote data platform after receiving this hydrogenation data.
The hydrogenation data is determined by the hydrogenation station according to the vehicle data and the hydrogenation data, the vehicle data is sent to the hydrogenation station when the fuel cell vehicle carries out the hydrogenation, the hydrogenation data is determined after the hydrogenation is finished at the hydrogenation station, namely the fuel cell vehicle sends the vehicle data to the hydrogenation station when the hydrogenation is carried out at the time, the hydrogenation station determines the hydrogenation data after the hydrogenation is finished at the hydrogenation station, and then the hydrogenation station combines the hydrogenation data with the vehicle data to determine the hydrogenation data.
In order to reliably transmit vehicle data to a hydrogen adding station by a fuel cell vehicle, in some embodiments of the present application, the vehicle data is transmitted to the hydrogen adding station by the fuel cell vehicle through an infrared signal, the vehicle data includes a license plate number, a vehicle identification number, a fuel cell number, a hydrogen storage system number, a driving distance, a statistical fuel cell power generation amount and a statistical hydrogen consumption amount of the fuel cell vehicle, and the hydrogen adding amount data includes the present hydrogen adding amount and hydrogen adding time information.
