SAE International and Intel announced the formation of the Vehicle Platform Power Management Committee (J3311). 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.
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,” said Christian Thiele, ground vehicle standards director at SAE international. “It is vitally important for the industry, as well as academia and government, to come together to help drive these efficiencies to make these vehicles more sustainable.”
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.
“There is much to be gained in applying proven-in-use concepts from standards created for the PC industry over the last 20 years,” added Jack Weast, Intel Fellow, VP and GM of Intel Automotive. “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.”
