Find and compare hydrogen refueling data interfaces (RDI) from leading B2B suppliers using technical specifications. The RDI sends data to a hydrogen filling station during refueling, via an infrared communication link. Information like receptacle type, tank volume, measured pressure and temperature etc. is transmitted from the vehicle to the station. The main purpose of the hydrogen RDI system is to facilitate the process by which the filling station fills the hydrogen storage tank of the vehicle in a very short time without the temperature or any other relevant parameters exceeding predefined safety thresholds.
