  • Patent number: 8054038
    Abstract: A method and apparatus for optimizing the level of battery charging required by an electric vehicle is provided. The system includes an interface for the user to input various travel parameters, such as a travel itinerary, which is then used by the battery charging system during charge optimization. In addition to a travel itinerary, the system may be configured to take into account departure times, road conditions, traffic conditions and weather conditions in determining miles to be traveled as well as the electrical energy per mile conversion factors to be used during optimization.

  • Publication number: 20100316894
    Abstract: A system for integrating the venting feature of a battery with a means for simultaneously disconnecting the cell from the battery pack, thereby isolating the cell, is provided. The provided battery interconnect system is comprised of a battery, a connector plate for electrically coupling the battery to a battery pack, and an interruptible electrical connector for electrically coupling the connector plate to a battery terminal vent. The vent, defined by scoring on the battery terminal, ruptures when the internal battery pressure exceeds the predefined battery operating range, causing the interruptible electrical connector to break and disrupt electrical continuity between the connector plate and the battery terminal.

  • Publication number: 20100212339
    Abstract: A method and apparatus for actively cooling the battery pack of an electric vehicle after the vehicle has been turned off, thereby limiting the adverse effects of temperature on battery life, are provided. Different battery pack cooling techniques are provided, thus allowing the cooling technique used in a particular instance to be selected not only based on the thermal needs of the battery pack, but also on the thermal capacity and energy requirements of the selected approach.

  • Publication number: 20100212338
    Abstract: A method and apparatus for limiting the adverse effects of temperature on the electrical energy storage system (ESS) of an electric vehicle after the vehicle has been turned off are provided. In general, whether or not coolant is circulated through a coolant loop coupled to the ESS depends on the difference between the ambient temperature and a preset temperature, the preset temperature typically corresponding to the temperature of the ESS.

  • Patent number: 7782021
    Abstract: One embodiment of the present subject matter includes a system that includes a battery, an electric vehicle, the battery coupled to the electric vehicle to propel the electric vehicle, and a charging circuit to charge the battery. The embodiment includes a charging cost circuit to estimate a charging cost rate and to turn on the charging circuit. The embodiment also includes a timer circuit to provide a time signal to the charging cost circuit. The embodiment is configured such that the charging cost circuit is to turn on the charging circuit during a first time period in which the charging cost rate is below a first threshold until the battery reaches a first energy stored level, and to turn on the charging circuit during a second time period in which the charging cost rate is above the first threshold.

  • Publication number: 20100211242
    Abstract: One embodiment includes a method that includes monitoring a battery state of charge circuit that is coupled to a vehicle battery, calculating an averaged value of the state of charge over a time period, charging the vehicle battery by powering a generator with a fuel burning engine that powered on and powered off according to one of a first operational mode and a second operational mode, wherein in the first operational mode the engine is powered on when the battery state of charge drops below a first state of charge and continues until the averaged value of the state of charge increases to a first preprogrammed value.

  • Publication number: 20100136407
    Abstract: The adverse effects of the dielectric material covering the lateral outer surface of a conventional battery are eliminated by replacing it with a dielectric barrier that covers less than 20 percent of the lateral outer surface of the cell case; more preferably less than 15 percent of the lateral outer surface of the cell case; still more preferably less than 10 percent of the lateral outer surface of the cell case; and yet still more preferably less than 5 percent of the lateral outer surface of the cell case. The dielectric barrier may be shrunk-fit, bonded, friction-fit or otherwise held in place. An electrically insulating disk may be interposed between the dielectric barrier and the end edge portion of the cell case.

  • Publication number: 20100104935
    Abstract: One embodiment includes an electrical cell that includes a flat housing, at least one electrode and an electrically and heat conductive tab coupled to the electrode and extending through the housing for electrically and thermally coupling to a collector panel, the tab being capable of conducting both current and a substantial amount of heat out of the housing to a temperature control system. The cells may be stacked to form a battery having a temperature panel interfaced to the temperature control system by a thermal interface. The battery may propel an electrically-powered vehicle or the like.

  • Patent number: 7683575
    Abstract: A method and apparatus for deactivating a bad battery cell from a battery pack for an energy storage system of an electric vehicle is disclosed. The apparatus and methodology includes a clamshell member arranged at an end of the cells and a printed circuit board arranged adjacent to the clamshell member. A collector plate is arranged adjacent to the printed circuit board and a switch is arranged on the printed circuit board. A wire bond is arranged between the switch and one of the cells and a second wire bond is arranged between the switch and the collector plate. The plurality of switches will allow for the identification of the one individual cell having a weak short circuit within the battery pack. Upon identification of the cell with the weak short circuit that cell will have its switch placed in an open position thus electrically isolating the faulty or bad cell from the battery pack.
