Abstract: The apparatus of the present invention is adapted to supply power to one or more of the belt driven accessories of a hybrid electro-mechanical vehicle while the engine is off. Additionally, the power may be provided to multiple accessories with a single electric motor thereby saving the cost associated with manufacturing and installing a separate electric motor for each accessory. The apparatus includes an electric motor, a motor clutch, an engine clutch, and an accessory drive belt. When the engine is on, the accessory drive belt transfers torque from the engine crank shaft to the belt driven accessories. When the engine is off, the accessory drive belt transfers torque from the electric motor to the belt driven accessories.
