Electric Vehicle E/E Architectures - Evolutionary or Revolutionary?

I appreciate Mentor Graphics inviting me to moderate a panel discussion at the Design Automation Conference (DAC). The topic: Electric Vehicle Electrical/Electronic Architectures – Evolutionary or Revolutionary. Based on first impressions it appears that the session will be lively. If you’re planning to attend, the session starts at 4:00 pm on Tuesday, June 3 in room 309.

The session topic is the degree to which the automotive electrical system architecture must either be altered (evolutionary) or fundamentally redesigned (revolutionary). Panel members will explore different opinions and discuss various implications.

Panel members scheduled to participate are:

Naehyuck Chang, Professor of Electrical Engineering in the CAD-X Laboratory at Seoul National University;

Aftab Khan, Vice President of Global Hybrid Engineering, Lear Corporation;

Ash Punater, software group leader, Delphi Electronics and Safety;

Sebastian Steinhorst, Research Fellow, RP3 – Embedded Systems, TUM CREATE Ltd., and

Ian Wright, founder and CEO, Wrightspeed, Inc.

Energy Sustainability for Massive EV Charging

“I am in the revolutionary side,” says Chang, “not primarily because of the EV design and manufacturing hurdles but mostly because of energy sustainability for massive EV charging. I will focus on energy requirement/efficiency of EV and how revolutionary design can support sustainable EV infrastructure.”

Steinhorst believes that the fundamental changes EVs introduce for automotive E/E architectures provide “an incredible opportunity” to revolutionize their design paradigms.

He says modularity will be a key aspect that could reduce development cost by using intelligent plug-and-play components that interface automatically and provide adapted functions across architectures and platforms.

“From a sustainability perspective, modularity would enable certain components of the E/E architecture to be exchanged and upgraded where otherwise the car would be outdated. From an interoperability perspective, modularity would enable, for instance, battery swapping with a standardized interface and package, or modular battery architectures where batteries of different capacity can be combined from modules.”

Which side are you on?
