1. A cooling system for an electrified vehicle, the cooling system comprising:
a first cooling loop for circulating coolant for cooling at least one of power electronics and a motor/generator of the electrified vehicle, wherein the first cooling loop includes a first heat exchanger for exchanging heat with the coolant in the first cooling loop;
a second cooling loop for circulating coolant for cooling an energy storage device of the vehicle, wherein the second cooling loop includes a coolant chiller; and
a waste heat recovery loop including a second heat exchanger in thermal communication with the second cooling loop for exchanging heat in the coolant received from the energy storage device.
