Vehicle energy consumption management method and system, electronic equipment and vehicle

The invention relates to the technical field of energy consumption management, and provides a vehicle energy consumption management method and system, electronic equipment and a vehicle, and the vehicle energy consumption management method is applied to a target domain control node in a plurality of domain control nodes. The target domain control node is used for carrying out power supply control on a load of the target domain control node, other domain control nodes except the target domain control node in the plurality of domain control nodes and a chip on a board of the target domain control node, and the target domain control node carries out power supply control on the load of the target domain control node under the condition that the vehicle is powered off and enters a preset low-power-consumption processing mode. And controlling to close controlled electric channels of other domain control nodes, controlling to open a constant electric channel for detecting an external wake-up source, controlling to h
