SAE International and Intel announced the formation of the Vehicle Platform Power Management Committee (J3311) at CES 2024. The new SAE standard committee will accelerate progress by adopting and enhancing advanced power management concepts from the personal computer (PC) industry, helping all electric vehicles (EVs) become more energy-efficient and sustainable. Intel will chair the committee.

The focus of the new committee is to develop an automotive standard for Vehicle Platform Power Management. Inspired by proven-in-use power management techniques from the PC industry’s Advanced Configuration and Power Interface (ACPI) standard, the new SAE standard will define electronic control unit (ECU) interfaces and functions necessary to enable OEMs to develop and deploy context-aware, vehicle-wide optimal power generation and consumption while allowing differentiation in implementation.

By enabling EVs to become smarter about when and where the energy is needed, this approach holds immense potential for optimizing battery performance, reducing energy waste, and extending driving ranges for BEV, PHEV, HEV and even ICE vehicles that will still be an integral part of the emerging markets landscape.

There is much to be gained in applying proven-in-use concepts from standards created for the PC industry over the last 20 years. By extending proven concepts like ACPI to software-defined vehicles, we could yield substantial power savings at the vehicle level, which can ultimately solve the challenge of building a more sustainable long-term global EV supply chain.

In addition to Intel, the J3311 committee includes industry representation from Stellantis, HERE, and Monolithic Power Systems (MPS). The committee is open to additional industry participation, with the goal of delivering the first draft standard within 12 to 18 months.
