  • Publication number: 20220258571
    Abstract: A vehicle system is described that includes a multi-phase rotary electric motor rotatably coupled via a rotatable member to an air-conditioning compressor, and a remotely located rechargeable energy storage system (RESS). The RESS includes a first power inverter that is electrically coupled to the multi-phase rotary electric motor via a plurality of electric power cables, a second power inverter that is electrically coupled to a second electric machine, a DC power source, and a chiller. A controller is in communication with and controllably coupled to the first power inverter and the second power inverter. The controller is operative to control the first power inverter to operate the multi-phase rotary electric motor in an open-loop control scheme.

  • Patent number: 10317918
    Abstract: A thermal bypass valve includes a housing defining a bore along a longitudinal axis and having two inlet ports and two outlet ports; a cap disposed within the bore; a shuttle disposed within the bore and reversibly translatable towards and away from the cap along the longitudinal axis between a first fill position, a cooling position, and a bypass position; and an actuator configured for translating the shuttle along the longitudinal axis between the cooling position and the bypass position. The actuator is formed from a shape memory alloy and is transitionable between a first state and a second state in response to a temperature of the fluid.
