  • Publication number: 20240388118
    Abstract: The invention relates to a pre-charging switching device and a fuel cell device for automatically adjusting an output voltage of a fuel cell system and a battery voltage of a battery connected in parallel with respect to a load without a DC-to-DC converter connected therebetween. The invention further relates to a motor vehicle equipped therewith. The pre-charging switching device comprises an input connection for connecting the fuel cell system, an output connection for connecting to the battery and the load and an adjustment switching unit connected therebetween. The adjustment switching unit has a controllable limiting element and a regulating device coupled thereto and is configured for damped adjustment of the voltages by regulating a direct current carrying behavior of the limiting element depending on a fuel cell system current detected on the input side.

  • Publication number: 20240375526
    Abstract: The invention relates to an interconnection device for interconnecting several fuel cell modules. A base element is provided therein, which provides a matrix of contact points, which can be equipped with connecting elements for implementing different interconnections. The base element has two input connections and output connections for each fuel cell module to be connected. Further, two busbars are provided, each of which is connected to one half of the output connections and each of which provides an external contact for connecting an electrical load to be supplied by the fuel cell modules. For each provided parallel branch of fuel cell modules, a diode device is provided, which is connected between one of the input connections and one of the busbars and allows a current flow only in the direction from the respective input connection to the respective busbar.

  • Patent number: 10741986
    Abstract: A device for establishing an electric contact between an electric energy storage cell and an electrically conductive conductor plate structure via an electrically conductive conductor wire. A tool establishes an electric contact between the electrically conductive conductor wire and the electric energy storage cell, and establishes an electric contact between the electrically conductive conductor wire and the electrically conductive conductor plate structure. The tool has a tool element that is movable through a perforation on the side of a conductor plate structure at least with its free end. In the region of the free end, a contacting device is arranged or built for forming an electric contact between the energy storage cell.
