The impact of vehicle electrification on electrical system design

In this white paper, we will review some of the implications of autonomy and vehicle electrification, and then examine the technical implications of high voltage electrification on electrical system designs.

Simplify harness engineering and electrical systems design in automotive

Vehicle autonomy and electrification are demanding significant changes to their electrical and electronic architecture. The main factors driving these changes are high voltage systems, increased safety considerations and significant weight reductions needed to maximize vehicle range from electrification. Even more impactful is ‘Fail operational’ designs, hugely increased data network loading and virtual validation requirements for higher levels of vehicle autonomy. The race to electrified self-driving cars is accelerating.

High voltage electrification for design and safety

Meanwhile, high voltage electrification is quickly becoming a fixture in the mainstream automotive market today. High-voltage electrification puts additional pressure on the electrical and electronic architecture and EDS design teams. As design teams face the new challenges introduced by electrification, they are also under pressure to bring vehicles to market as quickly as possible to avoid being left behind. Manufacturers will need to adopt more advanced design methodologies to overcome the challenges of high-voltage electrification on tight timelines.

Siemens Capital, the most comprehensive software suite for auto electrical engineering

Siemens Digital Industries Software’s Capital product portfolio, which supports the electrical systems and network domains, is an example of how we can trans-form design capabilities across organizations. Using a model-based design paradigm, Capital can define system architectures and then, using built-in metrics and design rule checks, compare and contrast multiple potential architectures to ensure the platform design meets the original intent.
