  • Patent number: 8922049
    Abstract: A system is disclosed for extracting electrical power from a plurality of batteries of an electric vehicle for use by an electric device. The system may include a power inverter configured to convert a DC power output of the batteries to an AC power output usable by the electric device. The system may also include a power cable having a first end electrically connected to the batteries and a second end electrically connected to the power inverter such that the DC power output of the batteries is transmitted through the power cable to the power inverter. Additionally, the first end of the power cable may include a charger plug configured to be connected to the batteries through a charging receptacle of the electric vehicle.
    Type: Grant

  • Publication number: 20120139486
    Abstract: A system for extending the driving range of an electric vehicle is disclosed. The system may generally include a generator mounted on or within the electric vehicle and configured to generate a DC power output for recharging the batteries of the electric vehicle. The generator may include a controller configured to implement a charging algorithm for controlling the DC power output supplied to the batteries. The charging algorithm may be designed to maintain the batteries below a predetermined state-of-charge corresponding to a transition point in a charging cycle of the batteries between a bulk charging phase and an absorption charging phase. Additionally, the system may include a generator cable configured to electrically connect the generator directly to the batteries.

  • Patent number: 5826293
    Abstract: The present invention is a heated wiper blade comprising an elongated blade and a heating element connected to the electrical system of a vehicle. The heating element utilizes a material with a positive temperature coefficient of resistance placed between a pair of conductive members. The conductive members span the length of the heating element to provide a uniform distribution of heat through the length of the blade. Electrical connections to the heating element are preferably located at one end of the blade. The heating element can be located inside the blade or between a semi-rigid attachment member and an upper surface of the blade.
