Vehicle-mounted power supply control system, electric vehicle and vehicle-mounted power supply control method

Abstract

The embodiment of the invention discloses a vehicle-mounted power supply control system, an electric vehicle and a vehicle-mounted power supply control method. The vehicle-mounted power supply controlsystem comprises a main storage battery, a vehicle end electrical component and an automatic driving electrical component. The main storage battery is provided with a first power output interface anda second power output interface. The first power supply output interface is connected with the automatic driving electrical component, and the second power supply output interface is connected with the vehicle end electrical component; and the main storage battery is used for respectively controlling the power supply states of the two power supply output interfaces according to the interface control instruction. In the embodiment of the invention, the automatic driving electrical component can be independently controlled so that the influence of the fluctuation of the working voltage of the vehicle-end electrical component on the voltage of the automatic driving electrical component can be avoided, and the working stability of the automatic driving electrical component is improved.

Description

technical field [0001] Embodiments of the present invention relate to electrical control technology, and in particular to an on-vehicle power supply control system applied to automatic driving, an electric vehicle and an on-vehicle power supply control method. Background technique [0002] An existing electric vehicle is powered by a high-voltage battery for the power motor in the vehicle and other electric appliances at the vehicle end. With the development of autonomous driving technology, many electrical components used to support autonomous driving technology are gradually added to the vehicle, and these electrical components are generally powered by high-voltage batteries. [0003] In the current on-board power supply system, in order to ensure the safety of the high-voltage battery, the power supply circuit of the high-voltage battery will be disconnected when the driver controls the vehicle to turn off and the high-voltage battery is charged. As a result, the compone...
