Smart power distribution

Modern vehicles demand highly efficient and reliable power distribution systems to support an ever-growing number of electronic functions. Smart power distribution is at the heart of this evolution, enabling optimized energy management, enhanced safety, and improved overall vehicle performance. As automotive design shifts towards electrification and digitalization, the traditional 12V powernet is evolving into more robust 48V systems, forming the basis of scalable, flexible zonal architectures. This fully digital architecture facilitates the transition to a service-oriented Software Defined Vehicle (SDV), where power and data converge seamlessly to support advanced functionalities and future-proof vehicle platforms.

ST provides a comprehensive developer ecosystem with essential tools, software libraries, and reference designs to assist engineers in designing and integrating smart power distribution systems. These technical resources help streamline the development of scalable, flexible automotive solutions.
