A vehicle thermal management system includes a cabin thermal loop, a battery thermal loop, a parallel valve assembly, and a controller. The cabin thermal loop includes a first chiller in fluid communication with a vehicle cabin. The battery thermal loop includes a second chiller in fluid communication with a high-voltage battery. The parallel valve assembly selectively links the cabin and battery thermal loops and includes a three-way valve and a conduit system arranged with one another to selectively link the first chiller and the second chiller to deliver cooling capacity to the battery. The controller is programmed to, responsive to detection of an available amount of cabin thermal loop cooling capacity exceeding a detected passenger vehicle cabin cooling capacity request, output a command to the parallel valve assembly to release the excess cooling capacity from the cabin thermal loop to cool the HV battery.

Thermal management system for electrified vehicle

A vehicle thermal management system including a cabin thermal loop, a battery thermal loop, a parallel valve assembly, and a controller is provided. The cabin thermal loop may include a first chiller. The battery thermal loop may include a second chiller and a high-voltage (HV) battery. The parallel valve assembly selectively may link the thermal loops. The controller may be programmed to, responsive to detection of a high load condition, command the parallel valve assembly to link the thermal loops such that the chillers operate together to cool a vehicle cabin and the HV battery. The parallel valve assembly may include a three-way valve and a conduit system selectively connecting the chillers, the three-way valve, and the HV battery.

Methods and systems are provided for reducing aerodynamic drag on a moving vehicle. One example method comprises, during a first vehicle moving condition, operating the cooling fan, and during a second vehicle moving condition, selectively applying a braking torque on the fan.
