  • Publication number: 20240030721
    Abstract: An energy storage system includes a first system energy interface, a first storage module, and a first processing module. The first storage module includes a first energy interface, a first cell stack comprising a plurality of individual cells, and a first communication interface. The first processing module includes a second energy interface, a second communication interface, a first monitoring module, a DC-10 DC converter, a third communication interface, and the first system energy interface. The system is configured to electrically couple the first memory module to a second memory module depending on the first processing module and a second processing module.

  • Patent number: 10840779
    Abstract: A drive device for a motor vehicle includes at least one electric machine and at least one shaft, which shaft is rotatably mounted on a housing element of the drive device and can be driven by the electric machine. At least one discharge ring is provided by which the shaft is brought into electrical contact with the housing element in order to dissipate electrical charges from the shaft to the housing element via the discharge ring. The discharge ring is formed from an electrically conductive fluid.

  • Patent number: 9744865
    Abstract: A line for supplying electrical units with power of more than 3 kW in vehicles, comprising: at least two electrically conducting, oblong bus bars having a flat cross-section and two opposite ends in the longitudinal direction, the bus bars each being insulated from and extending parallel to each other; a foil shield surrounding the bus bars from a first of the ends to a second of the ends; a stranded drain wire running between the bus bars and the foil shield in the longitudinal direction from the first end to the second end; a pair of flexible electrical conductors at one of the ends of the bus bars, each surrounded by a shield and electrically connected at a first end to a respective one of the bus bars, with the shield of the conductors being electrically connected in each case to the stranded drain wire.

  • Patent number: 6693368
    Abstract: A power supply system for a motor vehicle has a low-voltage onboard power supply and a higher-voltage onboard power supply. Either the minus connection or the plus connection of at least the high-power consuming devices of the higher-voltage onboard power supply is coupled via a central bus line with the corresponding (minus or plus) connection of the low-voltage onboard power supply. The central bus line is provided with a controllable switch. Devices are provided for measuring the voltage of the low-voltage onboard power supply, and/or for measuring the differential current between the current flowing on the plus line and the current flowing on the minus line in the higher-voltage onboard power supply. The controllable switch is opened when the voltage in the low-voltage onboard power supply has exceeded a defined voltage threshold and/or when the differential current has exceeded a defined current threshold.
