BAS Hybrid

BAS Hybrid

BAS is an acronym for Belted Alternator Starter. It is a category of automotive parallel hybrid technology that uses an electric motor to contribute power to the internal combustion engine's crankshaft via a serpentine belt. By mounting this motor generator unit in the conventional location traditionally used for the standard automotive alternator, it permits a low-cost method of adding mild hybrid capabilities such as start-stop, power assist, and mild levels of regenerative braking. BAS differ from other mild hybrid systems as they are not run off the vehicle's crankshaft.
