Thermal Management System for Electrified Vehicle

A vehicle thermal management system comprising:

• a cabin thermal loop including a first chiller in fluid communication with a vehicle cabin;
• a battery thermal loop including a second chiller in fluid communication with a high-voltage (HV) battery;
• a series valve assembly to selectively link the cabin and battery thermal loops including 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 HV battery;
• and
• a controller 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 series valve assembly to release the excess cooling capacity from the cabin thermal loop to cool the HV battery.

A vehicle thermal management method comprising:

• detecting a high load condition of a vehicle
• including a cabin thermal loop including a vehicle cabin, and
• in fluid communication with a battery thermal loop including a high-voltage (HV) battery;
• outputting, via a controller, a command to a valve assembly to fluidly link the cabin thermal loop and the battery thermal loop;
• and
• outputting, via the controller, a command to a first chiller of the cabin thermal loop and a second chiller of the battery thermal loop to selectively distribute cooling capacity to the vehicle cabin and to the HV battery such that excess cooling capacity of the cabin thermal loop assists in cooling the HV battery.
