  • Patent number: 8627860
    Abstract: A fuel delivery system and method of use are provided that may be used to open the door covering the charge port of an electric vehicle, or the door covering the fuel filler port of a conventional vehicle. The system includes a fuel coupler (e.g., a charging connector or a gas nozzle) designed to transfer fuel from the source to the vehicle via the vehicle's fuel port. The fuel coupler includes a switch that when toggled, causes a control signal to be wirelessly transmitted over a short distance. Upon receipt of the control signal by a receiver integrated into a vehicle that is in close proximity to the fuel port, an unlatching actuator within the vehicle unlatches the port door, thereby allowing it to open and provide port access.

  • Patent number: 8618775
    Abstract: A controller identifies a condition of a hazardous internal short by comparing patterns of series element voltages to the last known balance condition of the series elements. If the loaded or resting voltage of one or more contiguous series elements uniformly drop from the previously known condition by an amount consistent with an over-current condition, an over-current internal short circuit fault is registered. The desired response is to prevent the affected series elements from heating to a hazardous temperature by summoning the maximum heat rejection capability of the system until the short ceases and the affected elements cool, the cooling function is no longer able to operate due to low voltage, or the affected series string has drained all of its energy through the short. Also includes are responses that allow the battery pack to continue to power the cooling system even though it may enter an over-discharged state.
