This Information Report will define 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.
Rationale: Increasingly stringent economy and range regulations are forcing increased efficiency in xEV and ICE applications. Increasing load from electrical devices, including ADAS hardware, vehicle controls, and user interfaces has forced complexity in vehicle electrical systems, driving weight and costs as maximum current draw of modern vehicles exceeds 200 amps on the 12V system. Leveraging experience from power management of personal portable devices, Vehicle Platform Power Management seeks to leverage concepts such as ACPI, Mission Profiles, Dynamic variable voltage, and advanced control algorithms to reduce electrical load and manage electrical components in an efficient manner.
