  • Publication number: 20240132338
    Abstract: The disclosure relates to a computer-implemented method for managing a mobile hydrogen refuelling system, the mobile hydrogen refuelling system comprising a hydrogen refuelling vehicle, a hydrogen supply vehicle, and a management system, wherein the method comprises obtaining from the hydrogen refuelling vehicle a first set of data relating to the hydrogen refuelling vehicle, obtaining from the hydrogen supply vehicle a second set of data relating to the hydrogen supply vehicle, in the management system, and obtaining map data relating to an area of operation of said hydrogen refuelling vehicle and said hydrogen supply vehicle. Further, the method comprises determining a resupply location based on said first set of data, said second set of data and said map data, and providing the hydrogen refuelling vehicle and/or the hydrogen supply vehicle with navigation instructions to the resupply location for resupplying the hydrogen refuelling vehicle with hydrogen from the hydrogen supply vehicle.

  • Publication number: 20230396075
    Abstract: The present disclosure relates to a method of controlling electric charging of at least two electrically powered machines. The method is performed by a charging station comprising a plurality of electric energy sources, a charging interface for electrically connecting with an electrically powered machine, and a control unit. The method comprises collecting data about each one of the at least two electrically powered machines and obtaining a status of each one of the plurality of electric energy sources. The method further comprises determining a charging strategy based on the collected data, the obtained status and on a pre-determined charging focus of the charging strategy, and subsequently charging the at least two electrically powered machines according to the determined charging strategy. The present disclosure further relates to a control unit, a charging station and a vehicle or vessel comprising the charging station.

  • Publication number: 20230194052
    Abstract: The disclosure relates to an electrically powered mobile fluid supply system (MFSS) for supplying fluid to a host unit. The MFSS comprises at least one pressurized fluid volume, a fluid dispenser fluidly connectable to the host unit and configured to supply fluid from the at least one pressurized fluid volume to the host unit in a fluid supply operation, and at least one compressor configured to build sufficient pressure for the fluid supply operation in the MFSS. The MFSS is configured to be electrically connected to the host unit and the at least one compressor is configured to be electrically connected to the MFSS and electrically powered by the host unit during the fluid supply operation. The disclosure further relates to a method for supplying fluid to a host unit, to a control unit configured to control the fluid supply operation, and to the MFSS.

  • Patent number: 8215671
    Abstract: An air-bag for use in a safety arrangement in a motor vehicle includes a front panel and a rear panel. The two panels are superimposed and attached to one another around their peripheries in order to define an inflatable chamber. The front panel is provided with an aperture within which is secured an additional panel. The additional panel has an area greater than the aperture and is configured so as to define a plurality of adjacent substantially wave-shaped projections which extend forwardly from the front panel when the air-bag is inflated.
