Abstract

Embodiments of the present invention provide a control method for high-voltage power-on of a vehicle, a vehicle controller, a system, and a vehicle, wherein the control method includes: controlling the vehicle according to the received first signal sent by the one-button start controller Power on the low-voltage system; when it is detected that the low-voltage system of the vehicle is powered on, send the first wake-up signal to the DC converter, and control the high-voltage system of the vehicle to power on; when it detects that the high-voltage system of the vehicle is powered on, send the first An enable signal and a control signal to the DC converter. In the technical solution provided by the present invention, the vehicle controller controls the DC converter to switch to the working state after the high-voltage system of the vehicle is powered on, and converts the high-voltage power of the power battery into low-voltage power to supply power for the low-voltage system of the vehicle , and charge the battery to reduce the consumption of the battery only powered by the battery after the vehicle is powered on at low voltage, which is beneficial to avoid the battery power loss caused by the battery for a long time and the impact on the next start of the vehicle.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a control method for high-voltage power-on of a vehicle, a vehicle controller, a system and a vehicle. Background technique [0002] In the existing technology of electric vehicles, when the driver only presses the start-stop button, the whole vehicle is powered on at low voltage, and most of the low-voltage controllers and electrical equipment are awakened and are in a workable state. The driver uses low-voltage electrical equipment. At the time, the low-voltage current of the vehicle may be as high as more than 10A, and the low-voltage power supply of the vehicle is a 12V low-voltage battery. Under this condition for a long time, the power of the low-voltage battery will be quickly consumed, which will cause the battery to lose power easily. There is a risk that the vehicle will not start the next time the driver starts the vehicle. At the same time, when the vehicl...
