  • Patent number: 10322627
    Abstract: An energy storage system comprising at least one energy storage module adapted to supply electrical energy to a hybrid vehicle. The energy storage module comprises an enclosure, at least one battery array located within the enclosure, and an energy storage controller module located within the enclosure and electrically connected to the battery array. The energy storage module further comprises a compliant tipped thermistor which may be installed within a flexible clip. The thermistor is positioned to monitor the temperature of one or more of the batteries within the energy storage system.

  • Patent number: 9054401
    Abstract: An energy storage system comprising at least one energy storage module adapted to supply electrical energy to a hybrid vehicle. The energy storage module comprises an enclosure, at least one battery array located within the enclosure comprised of one or more battery cells held in place between side rails and secured by end plates and mounting pins. The end plates also include flanges which secure the end plates behind the pins. The pin arrangement provides more secure holding and helps prevent torque loosening during operation. The battery array also includes cell retainers between each cell to reduce thermal transfer between cells, and an insulation liner between the battery cells and the side rails to improve creepage and clearance.

  • Patent number: 7775810
    Abstract: A voltage tap apparatus functions as both a voltage tap and a cell isolator for conductive case battery cells that are joined end-to-end in a series chain. The apparatus includes conductive leadframe elements partially encased in a plastic frame that engages the joined cells about their juncture, with portions of the lead-frame elements exposed to electrically contact the conductive cases of the cells. In a first embodiment, the plastic frame is in the form of a hinged clamp that closes about the juncture of the cells, and the lead-frame elements are routed to terminals formed on one end of the frame. In a second embodiment, the plastic frame and a connector are mounted on a printed circuit board and the leadframe elements in the plastic frame couple the battery cells to the connector.

  • Patent number: 5021794
    Abstract: The radio transmitter in a miniaturized transceiver concealed on a person to be located, such as a lost child, is activated and transmits a coded UHF radio homing signal upon receipt of an initiating signal containing the child's address code. The initiating signal is automatically transmitted by a repeater station in response to an audible "panic signal" containing the address code and contains the identical address code. The panic signal is a pulse tone produced by a hand held tone generator activated by the child's parent and is transmitted to the repeater station by telephone. Tracking vehicles are provided with automatic UHF radio direction finding and distance measuring equipment for locating the source of the homing signal. Stored information concerning the child can be transmitted to the tracking vehicles.
