Starter motor generator
WARNING: This page does not describe the selected car, but rather 45 other vehicles, including the 2016 BMW M5, 2016 BMW 550i xDrive, 2016 BMW 550i, 2016 BMW 535i xDrive, and 2016 BMW 535i. However, it is still accessible from the selected car via links, so may be relevant.
The starter generator is integrated in the belt drive. Using a starter generator means that a second belt tensioner is required. The crankshaft starter generator enables a comfortable transition from electric driving to driving powered by the combustion engine. The energy supplied by the auxiliary battery makes it possible to quickly start the engine with very low noise without requiring an additional torque in the electrical machine.
The crankshaft starter generator is connected to the digital motor electronics (DME) via a local interconnect network bus (LIN). If there is a fault in the DC/DC converter or the high-voltage system, the starter generator can take over the supply of the 12 V electrical system.
