  • Patent number: 10522845
    Abstract: A method of regulating thermal dissipation from a vehicle battery pack is provided in which a by-pass valve is used to control the amount of battery pack coolant either passing through, or by-passing, a heat exchanger, where the coolant passing through the heat exchanger is cooled by a refrigeration system. The vehicle's HVAC system is controlled to insure that HVAC operation does not compromise maintaining the battery pack within an acceptable range of temperatures.

  • Patent number: 10427491
    Abstract: A thermal management system and method of use are provided, the system including a heat exchanger, a refrigeration system, a coolant loop thermally coupled to the heat exchanger, and a by-pass valve that regulates the amount of coolant within the coolant loop that either passes through the heat exchanger or is diverted away from the heat exchanger. The coolant loop is thermally coupled to the battery pack of an electric vehicle.

  • Patent number: 9758010
    Abstract: A multi-mode vehicle thermal management system is provided that allows efficient thermal communication between a refrigerant-based thermal control loop and three non-refrigerant-based thermal control loops, where one of the non-refrigerant-based loops provides temperature control over the vehicle's passenger cabin, a second of the non-refrigerant-based control loops is thermally coupled to the vehicle's battery system and the third of the non-refrigerant-based control circuits is thermally coupled to the vehicle's drive train. The refrigerant-based control loop may be operated either in a heating mode or a cooling mode and is coupled to the vehicle's HVAC system using a refrigerant-air heat exchanger, and to the battery thermal control loop using refrigerant-fluid heat exchangers. A valve assembly is used to couple and/or decouple the battery and drive train thermal control loops, thereby allowing these two thermal control loops to operate either in parallel or in series.

  • Publication number: 20160272120
    Abstract: A retractable storage compartment that is accessible by the passengers in the rear portion of a vehicle's passenger cabin is provided. The storage compartment, which is integrated into the vehicle's center console, is mounted on a guide assembly in order to allow a rear passenger to easily open or close the compartment. The compartment may be configured as a simple storage area, or equipped with any of a variety of features such as an insulated ice chest, a refrigerator unit, a fold-out desk, etc. In addition to providing rear passenger access, the compartment may be configured to allow the passengers seated in the front of the car to access the compartment using a secondary, top-mounted door.

  • Patent number: 9250020
    Abstract: A vehicle thermal management system is provided that includes two or more heat exchangers configured in a non-stacked arrangement, where separate air inlets corresponding to each of the heat exchangers allow a direct intake of ambient air. Active louver systems consisting of sets of adjustable louvers and a control actuator are used to control and regulate air flowing directly into one or more of the heat exchangers, where the adjustable louvers are either adjustable between two positions, i.e., opened and closed, or adjustable over a range of positions. Air ducts may be used to couple the output from one heat exchanger to the input of a different heat exchanger.
