Abstract
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.
Claims16
An automotive system comprising:
- an electric machine including a stator defining slots and a plurality of hollow wires wound within the slots;
- and
- a pump configured to drive coolant through the hollow wires to cool the electric machine.
An automotive system comprising:
- a controller programmed to, based on a temperature of a battery, selectively direct coolant through a coolant circuit for the battery and hollow windings of an electric machine.
A method comprising:
- responsive to a temperature of a battery being less than a threshold temperature, directing coolant from hollow wires wound within slots of a stator to a coolant circuit for the battery;
- and
- responsive to the temperature being greater than the threshold temperature, directing the coolant from the hollow wires back to the hollow wires while bypassing the coolant circuit.
