  • Publication number: 20230013123
    Abstract: Electrochemical cell battery system and associated methods of operation are provided based on the incorporation of a thermal suppression construct including a supply of cooling fluid dispensed in intimate contact with the cells disposed within an enveloping sealed enclosure. The electrochemical cells are connected electrically by bus bars to form a battery of cells. The bus bars support cooling by convection methods. The cells are allowed to float mechanically as they are charged and discharged while maintaining intimate thermal contact with the enveloping sealed enclosure through conduction and the bus bars through conduction. The system provides a method of cooling the cells by conduction and convection and that accommodates mechanical changes to both the cells and the enveloping sealed enclosure.

  • Patent number: 8258727
    Abstract: The regenerative torque shifter is a system for electric/hybrid electric vehicles that includes a driver-operated control device mounted in the vehicle and a control unit linked to a motor controller. The driver sets a level of regenerative braking desired by manipulating the control device. Based on output from the control device, the control unit directs the motor controller to apply a corresponding level of regenerative braking action by varying the amount of load seen by the motor.
