Abstract: A system for controlling fluid temperature includes a heat source, a heat sink coupled to the heat source such that a flow of coolant passes between the heat source and the heat sink, a first heat exchanger coupled to the heat source, a second heat exchanger coupled to the heat source, a valve coupled to the heat source, the first heat exchanger, the second heat exchanger, and the heat sink, the valve configured to regulate the flow of coolant between the heat source, the first heat exchanger, the second heat exchanger, and the heat sink, and a controller in electronic communication with the heat source and the valve. The controller is configured to determine an operating condition and generate a control signal to control the valve to direct the flow of coolant to one or more of the first and second heat exchangers and the heat source.

Abstract: A vehicle thermal management system includes a radiator receiving a liquid coolant in a coolant supply line and discharging the coolant into a coolant pump supply line. A coolant pump receives the coolant from the coolant pump supply line and discharges the coolant into multiple engine components. A transmission oil heat exchanger defining a first transmission oil heat exchanger receives the coolant after being discharged from the multiple engine components. An air-to-coolant sub-cooling heat exchanger defines a second transmission oil heat exchanger. The sub-cooling heat exchanger receives a portion of the coolant bypassing the multiple engine components.

Abstract: A charging station for a vehicle, a system and a method of charging the vehicle. The system includes a heat exchanger at the vehicle. The charging station includes a reservoir including a charging station coolant, a dispenser unit configured to circulate the charging station coolant from the reservoir through the vehicle to absorb heat generated at the vehicle, and a cooling unit for cooling the charging station coolant from the reservoir. Heat generated during the charging of the vehicle is transferred into a vehicle coolant circulating within the vehicle. The heat is transferred from the vehicle coolant to a charging station coolant. The charging station coolant is flowed out of the vehicle.

Abstract: A system for controlling fluid temperature in a thermal system includes a heat source, a heat sink coupled to the heat source, a first heat exchanger and a second heat exchanger, a first expansion valve configured to regulate the flow of coolant between the heat source and the first heat exchanger, a second expansion valve configured to regulate the flow of coolant between the heat source and the second heat exchanger, and a controller. The controller is configured to determine an operating condition of the thermal system and generate a first control signal to control the first and second expansion valves to direct the flow of coolant to the first and second heat exchangers. The first and second expansion valves are arranged in parallel to recover heat rejected from the coolant and distribute the recovered heat to the first and second heat exchangers.

Abstract: A pickup truck including a passenger compartment, a cargo bed operatively coupled to the passenger compartment, and a selectively deployable drag reduction system mounted at the cargo bed. The selectively deployable drag reduction system includes a deflector that is shiftable between a non-deployed configuration and a deployed configuration. In the deployed configuration the deflector is exposed to an airflow passing over the pickup truck.

Abstract: A shutter system is provided for a vehicle having an internal combustion engine that receives forced intake air and is cooled by an engine coolant. The vehicle includes a charge air cooler system having an intercooler for cooling the intake air and an engine cooling system. The shutter system includes a shutter positioned downstream of the intercooler and an actuator for moving the shutter between first and second positions. The shutter system further includes a sensor for generating a signal associated with a temperature of the intake air and a processor for comparing the temperature to a threshold. The actuator moves the shutter to the first position in response to receiving the first signal when the temperature is below the threshold. The actuator moves the shutter to the second position in response to receiving the second signal when the temperature is above the threshold.
