Problems solved by technology

[0006] The low-voltage power-on state will consume the power of the low-voltage battery
When the voltage value of the low-voltage battery is lower than a certain value, the low-voltage battery cannot supply power to the low-voltage controller of the vehicle controller, and the low-voltage controller cannot be initialized, so the vehicle cannot be started normally
In this case, you can only replace the low-voltage battery, or use an external power supply to start the vehicle

Abstract

Embodiments of the invention provide a charging control method and apparatus for a low-voltage storage battery of a vehicle, and the vehicle. The charging control method comprises the steps that when the vehicle is under a high-voltage power-off state, the charging control apparatus for the low-voltage storage battery of the vehicle determines whether the low-voltage storage battery of the vehicle needs to be charged or not; and when the low-voltage storage battery needs to be charged, the charging control apparatus controls the vehicle to be in a high-voltage power-on state so as to charge the low-voltage storage battery. By adoption of the technical scheme, the problem that the vehicle cannot be started caused by over-low voltage value of the low-voltage storage battery can be avoided.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of vehicles, and more specifically, relate to a method and device for controlling charging of a low-voltage battery of a vehicle, and the vehicle. Background technique [0002] Vehicles powered by batteries (for example, electric vehicles, hybrid vehicles, etc.) generally include the following three working states: an on state, an off state, and a charging state. [0003] From the off state to the start state, the vehicle will go through the low-voltage power-on state and the high-voltage power-on state in sequence. Specifically, when the driver starts the vehicle, the vehicle starts to enter a low-voltage power-on state. At this time, the low-voltage circuit of the vehicle is turned on, and the low-voltage battery starts to supply power to wake up various low-voltage controllers in the vehicle, such as the vehicle controller and power management system. After the initialization of th...
