  • Patent number: 9187004
    Abstract: A system providing a driver of an electric vehicle with the ability to exchange a depleted battery with a charged battery. Information regarding the status of an electric battery is transmitted to service stations, and information is returned to a driver indicating the location of a service station with a charged battery. The driver enters the station and is automatically positioned next to a rotating carousel. A robotic arm removes the depleted battery from the vehicle and pulls it onto the carousel, which rotates and deposits the battery onto a return conveyor belt, which carries the battery to a transportation platform for movement to a battery rack for charging. The transportation platform removes a charged battery from the battery rack and carries it to an outgoing conveyor belt, which carries it to the carousel, which rotates until the battery is next to the vehicle for insertion by the robotic arm.
