Abstract

The invention relates to the technical field of electric vehicles, and discloses an electric vehicle low-voltage system control method, device and equipment and a storage medium. In the invention, a key gear state of an electric vehicle can be obtained, and when the key gear state is in an ON gear state, a direct-current converter is controlled to enter a starting state; according to the invention, the state of charge of the storage battery is determined according to the storage battery information, and when the state of charge of the storage battery is less than or equal to the preset state of charge, the direct-current converter is controlled to supply power to the whole vehicle low-voltage system of the electric vehicle, thereby avoiding power shortage of the storage battery and improving the working efficiency of the direct-current controller. And the power supply of the whole vehicle low-voltage system can be effectively controlled by combining the state of the storage battery andthe actual demand of the whole vehicle low-voltage system.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a control method, device, equipment and storage medium for a low-voltage system of an electric vehicle. Background technique [0002] At present, the low-voltage power supply of electric vehicles mainly uses batteries and DCDC devices (Direct Current, DC converters) in parallel for joint power supply. The main function of the battery is to power up the vehicle at high voltage. In the power-on state, the DC converter is turned on to convert the high-voltage power of the power battery into the low-voltage power of the vehicle, continuously supplying power to the low-voltage load of the vehicle, and charging the battery. [0003] In the prior art, when the vehicle is powered off at high voltage, the battery provides low-voltage power supply for the vehicle; when the vehicle is powered on at high voltage, the DC converter starts up and continuously outputs to supply power t...
