Advanced power management in electric vehicles (EV) holds the promise of significant reduction in vehicle power usage. With over 100 electronic control units (ECUs) in a typical modern EV, power savings from a reduced electrical load can yield increased vehicle range, reduced vehicle weight due to a smaller battery pack, decreased charging times, and diminished safety risks.

The SAE J3311 Vehicle Platform Power Management committee was formed early in 2024 to develop standards that will “define platform interfaces to enable OEMs to deploy context-aware optimal power generation and consumption solutions in EVs that also continue to allow implementation differentiation.” Putting it briefly, to save energy.

The development of Advanced Configuration and Power Interface (ADPI) for personal computers, which was spearheaded by Intel, enabled significant power savings in portable computers. Applying this solution to EVs seeks to achieve similar results. Standardization of EV electronic architecture is needed, however, since most OEM’s design their own solutions.

The J3311 committee is chaired by Gary Martz, Senior Director Intel Automotive, Advanced Technology Solutions at Intel. The committee is actively seeking additional volunteer members with expertise in electric or cybersecurity design to contribute their expertise to the work of the group.

If you would like to know more about the work of the J3311 committee, or you are interested in volunteering your experience and knowledge to help develop standards to achieve its goals, contact SAE’s Dante Rahdar, Ground Vehicle Committee Manager, at: dante.rahdar@sae.org.
