Abstract: A vehicle includes a refrigerant system having a chiller and a coolant system having a chiller loop and a radiator loop. The chiller loop is arranged to circulate coolant through the chiller, and the radiator loop is arranged to circulate coolant through a battery, a radiator, and a bypass valve connected to a bypass conduit. A controller is configured to, in response to an ambient-air temperature exceeding a battery-coolant temperature, actuate the valve to circulate coolant to the bypass conduit to skip the radiator.

Abstract: A vehicle includes a traction battery arranged to be cooled by a chiller of a refrigerant system, and a radiator of a coolant system. The coolant system includes a proportioning valve having a pair of first and second outlets that each selectively receives a proportion of coolant flowing into the valve depending upon a position of the valve. The coolant system further includes a chiller loop connected to the first outlet and arranged to convey coolant to the chiller, and a radiator loop connected to the second outlet and arranged to convey coolant to the radiator. A controller is configured to, in response to the refrigerant system being ON, actuate the proportioning valve to proportion the coolant between the first and second outlets such that heat transfer through the chiller is limited to a chiller capacity.

Abstract: A vehicle includes an HVAC system with compressor(s), pump(s), valve(s), chiller(s); a touchscreen and processor(s) configured to: (1) display a preconditioning scheduling interface having line segments; (2) in response to touchscreen tap(s): place points on the segments, cycle the placed points between different kinds of points; and (3) precondition the vehicle via the HVAC based on times associated with the placed points.

Abstract: A vehicle includes an engine arranged to output torque and an electric machine arranged to apply a reaction torque against engine output torque to generate power for charging a traction battery. The vehicle also includes a controller programmed to issue a command to adjust the engine output torque and an output speed corresponding to a predetermined optimal brake specific fuel consumption while providing power to charge the fraction battery, satisfy an accessory power demand, and propel the vehicle.

Abstract: A vehicle includes a traction battery and a cooling system. The cooling system has a chiller, a radiator, and conduit and valving arranged to form a thermal circuit configured to selectively transport heat via coolant from the traction battery to the radiator. The vehicle also includes a grille shutter assembly having an opening and shutters movable to alter an effective cross-sectional area of the opening. A controller is programed to operate the shutters to change the effective cross-sectional area of the opening to increase or decrease air flow over the radiator based on a temperature of the coolant and an ambient air temperature.

Abstract: A vehicle includes a refrigerant system having an intermediary heat exchanger, an exterior heat exchanger, and an expansion device disposed therebetween. The vehicle also includes a coolant circuit having a pump configured to circulate coolant through the intermediary heat exchanger and an engine. A controller is programmed to, in response to air conditioning being requested and the coolant temperature exceeding a threshold temperature, open the expansion device and de-energize the pump to condense refrigerant in the exterior heat exchanger.

Abstract: Systems and methods for operating a vehicle in an electric idle mode are presented. The vehicle electrical idle mode may be characterized as a mode where the vehicle's engine is off; the vehicle increases torque to vehicle wheels responsive to an application of an accelerator pedal, release of a brake pedal, or a vehicle occupant shifting a transmission; and the vehicle's battery supplies electrical energy to devices of the vehicle being operated by a vehicle occupant.

Abstract: A vehicle includes a battery arrangement, a chiller, a coolant circuit configured to direct coolant through the chiller and battery arrangement, a refrigerant circuit including a compressor, valve, and evaporator, and a controller. The controller is programmed to alter a speed of the compressor and a position of the valve based on a pressure and temperature of refrigerant output from the chiller to alter a temperature of the coolant.
