  • Publication number: 20240042872
    Abstract: An AC power grid in an electric or hybrid vehicle, having an AC charging socket, at least one socket for an electrical load, and a bidirectional inverter. The bidirectional inverter is connected on the AC side to the AC charging socket and to the at least one socket and is connected on the DC side to a high-voltage battery of a traction network. At least one microprocessor and at least one switching element are associated with the socket. The microprocessor of the socket is connected to a control unit of the inverter via at least one communication line. Depending on a state, the control device generates a switching command for the at least one switching element of the socket.

  • Patent number: 10737576
    Abstract: A method for a high-voltage energy system of a vehicle wherein a pre-accident error state is determined which shows the current existing error of the high-voltage energy system prior to the time of an accident. Then an accident event is determined. A post-accident error state is determined which shows the current existing error of the high-voltage energy system according to the time of the accident. The high-voltage energy system is deactivated in accordance with the accident, the pre-accident error state, and the post-accident error state.

  • Publication number: 20200087051
    Abstract: The invention relates to packaging for the thermally insulated transportation of cooled or hot goods, which packaging consists of a box with multi-layer wall material formed from corrugated board and bubble wrap and an insert formed from a cushion filled with wood shavings. The multi-layer material for the box in accordance with the invention consists of a multi-layer laminated or loosely stacked composite, which, from the outside to the inside of the box, has the following layer sequence: (a) one or more bubble wrap layers, which are laminated with an aluminum foil or have a foil layer metallized with aluminum; (b) one or more single-wall open corrugated boards; (c) one or more bubble wrap layers which are laminated with an aluminum foil or have a foil layer metallized with aluminum.
