  • Publication number: 20230249567
    Abstract: The present invention provides a scalable fast charging system for electric vehicles for large parking structures, curb-side charging, work-place charging, or MuD's charging. A centralized power processing unit processes power from AC to multiple HVDC outputs, with these multiple HVDC outputs available in small power increments that lend themselves to be easily paralleled and an optional energy storage system. A centralized switch matrix distributes and shares the power from the power processing outputs to any one, or any multiple, dispensers based on the power needs at the various dispenser. A centralized cooling system cools various cables and charging cables in the dispensers and is located away from the dispensers where more space is available. An array of small dispensers are installed at the point of use where the vehicles are to charge. Further, a switch matrix controller optimizes delivery of power to each of the dispensers to optimizer overall performance.

  • Publication number: 20220393492
    Abstract: A system for battery management, such as a kiosk, can include a plurality of battery holders. Each battery holder can have a lock that retains or releases a battery pack that is held in the respective battery holder. For each battery holder, a bidirectional inverter can have an alternating current (AC) stage that is electrically coupled to an AC bus, and a direct current (DC) stage that is electrically coupled to the battery pack in the respective one of the plurality of battery holders. Other aspects are described.
