Abstract
A vehicle includes an engine, an electric machine, a traction battery, and a controller. The controller, responsive to the vehicle not moving, a temperature of the traction battery being less than a temperature threshold, and a state-of-charge of the traction battery being greater than a state-of-charge threshold, rotates the engine via the electric machine powered by the traction battery while no fuel is supplied to the engine.
