BATTERY HEATING VIA HEAT COLLECTED FROM COOLANT PASSING THROUGH HOLLOW WINDINGS OF ELECTRIC MACHINE

Responsive to a temperature of a battery being less than a threshold temperature, a controller directs coolant from hollow wires wound within slots of a stator to a coolant circuit for the battery. Responsive to the temperature being greater than the threshold temperature, the controller directs the coolant from the hollow wires back to the hollow wires while bypassing the coolant circuit.
