Mercedes “S-Class” Powernet Architecture

The brand-new S-Class is the beacon of automotive luxury, which addresses evolving customer expectations and technical opportunities. We enter into a new era in the automotive Powernet domain. Optimization in both power availability and drive hybridization, as well as new features such as partial networking characterize the highly integrated state-of-the-art Mercedes powernet. The new S-Class offers heightened energy efficiency and increased reliability for further automation of driving and vehicle features. The systematically optimized E/E network architecture for the 2020 S-Class maximizes the availability of automotive electronics innovations. Mercedes-Benz further enhances the energy-efficient and cost-effective power supply with the improved 48V system. It prepares for the latest driver assistance and automation systems with a fail-safe 12V power supply. Furthermore, a new vehicle feature experience is defined before and after driving with a “Living” powernet. Since the initial launch in the 222 predecessor, the fully integrated 12V and 48V power network system increases the energy availability for additional comfort and chassis innovations with consumption-reducing EQ hybrid features culminating in the realization of the 223 model.
