THERMAL MANAGEMENT SYSTEM IN A VEHICLE AND METHOD FOR OPERATION OF THE SYSTEM

Thermal management systems and methods for operation thereof are provided for allocating coolant flow in a vehicle. The thermal management system includes a cabin heat exchanger in fluidic communication with a heater and an energy storage device heat exchanger in fluidic communication with the heater. The thermal management system is designed to, in a first mode, flow heated coolant from the heater to the cabin heat exchanger in a first coolant loop and flow cooled coolant to the energy storage device heat exchanger from an energy storage device cooler in a second coolant loop temporarily separated from the first coolant loop and, in a second mode, flow heated coolant from the heater to the cabin heat exchanger and then to the energy storage device heat exchanger in series.
