The method and apparatus of the present invention provide an accessory drive system for a belt-alternator-starter electric hybrid vehicle. The apparatus includes a drive pulley connected to an engine output shaft, a plurality of accessories that are each connected to a driven pulley, and a selectively engageable torque transmitting device disposed between the engine crankshaft and a transmission. A belt-alternator-starter system is connected to another driven pulley. A drive belt connectively couples the drive pulley and the driven pulleys and is operable to transfer drive forces between the drive pulley and the driven pulleys. A controller is operatively connected to the torque transmitting device, the engine and the belt-alternator-starter system. The controller is configured to control the torque transmitting device, the engine and the belt-alternator-starter system to ensure the accessories are adequately powered.
