1. A thermal management system for a vehicle that includes a traction battery, the thermal management system comprising:
a cabin coolant loop that provides thermal management of a passenger cabin of the vehicle;
a battery coolant loop that provides thermal management of the traction battery; and
a drivetrain coolant loop that provides thermal management of a drivetrain and power electronics of the vehicle, wherein
the cabin coolant loop, the battery coolant loop and the drivetrain coolant loop are interconnected via fluid control valves and fluid lines, and
a valve is used to divert coolant from the drivetrain coolant loop to both of the battery coolant loop and the cabin coolant loop, whereby waste heat from a drivetrain of the vehicle is used to thermally manage both the passenger cabin and the traction battery.
