SAE International, in collaboration with Intel, has established a new committee to advance the energy efficiency of EVs.

The Vehicle Platform Power Management Committee (J3311), which is chaired by Intel, aims to use power management principles from the PC industry to make all EVs more energy-efficient and sustainable. This new committee will establish a Vehicle Platform Power Management standard, which will define electronic control unit (ECU) interfaces and functions to enable OEMs to develop and deploy context-aware, vehicle-wide optimal power generation and consumption while allowing differentiation in implementation. The standard will use proven-in-use power management techniques from the PC industry’s Advanced Configuration and Power Interface (ACPI) standard.

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, and the goal is to deliver the first draft standard within 12 to 18 months.

“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,” said Christian Thiele, Director at SAE international.
