A vehicle includes an engine including a crank shaft; a battery; a belt-integrated starter generator (BISG) mechanically coupled to the crank shaft and configured to generate electric power from motion of the engine to charge the battery; and a controller configured to operate the BISG to apply a load to the crank shaft to slow the engine and capture electric power for storage in the battery, wherein an initial magnitude of the load is proportional to a temperature of the engine, responsive to a speed of the BISG or engine achieving a predetermined non-zero threshold, remove the load from the crank shaft, and bring the engine to a stop.
