Abstract

The invention provides a power saving method and device and related equipment, and relates to the technical field of electric automobiles, and the method comprises the steps: obtaining the state information of a vehicle and the first residual electric quantity of a low-voltage battery of the vehicle; when it is determined that the vehicle is in an idle state according to the state information and the first remaining electric quantity is lower than a first electric quantity threshold value, a power saving instruction is generated; according to the power saving instruction, low-power-consumption processing is conducted on target equipment of the vehicle, and the target equipment is electric equipment powered by the low-voltage battery. Whether the vehicle is in the idle state or not is recognized in time by obtaining the state information of the vehicle, and when the vehicle is in the idle state and the first remaining electric quantity of the low-voltage battery of the vehicle is lower than the first electric quantity threshold value, low-power-consumption processing is conducted on the target equipment in the vehicle, so that the low-voltage battery is prevented from being discharged too fast, and the electricity shortage risk of the low-voltage battery is reduced.

Description

technical field [0001] The present application relates to the technical field of electric vehicles, and in particular, to a power saving method, device and related equipment. Background technique [0002] Electric vehicles refer to vehicles that use on-board power as power and use motors to drive wheels. [0003] At present, the vehicle power supply usually includes two parts: high-voltage battery and low-voltage battery. The high-voltage battery is used to supply power to the high-voltage subsystem in the electric vehicle, and the low-voltage battery is used to supply power to the low-voltage subsystem in the electric vehicle. [0004] In the application, it is found that compared with the high-voltage battery that can be directly charged by the generator or the charging pile, the low-voltage battery that relies on the power supply of the high-voltage battery has a greater risk of power loss. SUMMARY OF THE INVENTION [0005] The purpose of the embodiments of the present...
