Vehicle low-voltage system on-demand power supply method, device and equipment and storage medium

The invention belongs to the technical field of new energy vehicles, and discloses a vehicle low-voltage system on-demand power supply method, device and equipment and a storage medium. The method comprises the steps of receiving a starting instruction of a vehicle control unit on a vehicle, and starting a first port according to the starting instruction; acquiring a low-voltage working demand ofa low-voltage module on the vehicle, and controlling the first port to supply power according to the low-voltage working demand; receiving a working instruction of an upper controller of the vehicle,and starting a second port according to the working instruction; and acquiring an additional work demand of the upper controller, and controlling the second port to supply power according to the additional work demand of the upper controller. In this way, only one set of low-voltage system can be used in the new energy automobile, and different voltage requirements in an automobile are met. 本发明属于新能源汽车技术领域，公开了一种车辆低压系统按需供电的方
