Methods and systems are provided for an electric axle in a vehicle. An electric axle includes an electric motor having a stator and a rotor, a coolant manifold mounted to a first end plate of the rotor, the first end plate opposite a second end plate distal to the coolant manifold, wherein the coolant manifold is configured to flow coolant to rotor coolant lines extending axially through the rotor, and a spray ring comprising coolant lines coupled to the coolant manifold, wherein coolant flowing from the coolant manifold to the spray ring flows in a direction angled to an axial direction, wherein the spray ring is positioned circumferentially about axial stator end windings and configured to spray coolant onto an outer diameter of the end windings, wherein the first end plate and the second end plate are configured to spray coolant onto an inner diameter of the end windings.
