The system includes a battery, a battery powered component powered by the battery, the battery powered component and the engine powered component being adapted to perform substantially the same functions, and a controller arranged to stop operation of the engine powered component so that additional engine power is available to the drive wheels, and to initiate operation of the battery powered component, when power sought to be delivered to the vehicle drive wheels from the engine reaches a predetermined percentage of maximum engine load.
