1. An assembly, comprising:
- a blend door positioned on an underside of an electrified vehicle and moveable between a first position and a second position, the blend door in the first position permitting a first flow of air to move toward a traction battery, the blend door in the second position permitting a second flow of air to move toward the traction battery, the first flow including more air that has moved through an engine compartment than the second flow, the second flow including at least some air that has not moved through the engine compartment; and
a blocker door separate from the blend door, the blocker door moveable between a flow-blocking position and a flow-permitting position, the blocker door in the flow-blocking position blocking the traction battery from receiving the first flow or the second flow, the blocker door in the flow-permitting position permitting the traction battery to receive the first flow or the second flow, wherein the blend door is closer to a front of the electrified vehicle than the blocker door.
