Embodiment 1

[0043] refer to figure 1 , showing a charging control method, the method includes:

[0044] Step S1: In response to the trigger request for charging, power on the vehicle at low voltage.

[0045] In this step, the vehicle is mainly a new energy vehicle. After the new energy vehicle responds to the trigger request for charging, the vehicle will be powered on at low voltage and then powered on at high voltage. When the low voltage is powered on, the vehicle is powered by the battery; when the high voltage is powered on, the vehicle is powered by the power battery. The power battery includes a high-voltage relay. When the high-voltage is powered on, the high-voltage relay is closed, and when the power is off, the high-voltage relay is disconnected.

[0046] Step S2: Determine the current remaining power of the power battery of the vehicle and the target power required by the user.

[0047] In this step, a VCU controller (Vehicle control unit) can be used to determine the curre...

Embodiment 2

[0068] Based on the same inventive concept, another embodiment of the present application provides a charging control device, including: a VCU controller, where the VCU controller includes:

[0069] The low-voltage power-on module is used to perform low-voltage power-on of the vehicle in response to a trigger request for charging;

[0070] a determining module, configured to determine the current remaining power of the power battery of the vehicle and the target power required by the user;

[0071] The high-voltage power-on module is configured to perform high-voltage power-on and start charging when the current remaining power of the vehicle is less than the target power required by the user.

[0072] In a feasible implementation manner, the VCU controller further includes:

[0073] The power-on prohibition module is configured to not perform high-voltage power-on when the current remaining power of the power battery of the vehicle is not less than the target power required ...

Embodiment 3

[0084] Based on the same inventive concept, another embodiment of the present application provides a vehicle, including a charging control system as provided in the second embodiment of the present application.

Abstract

The embodiment of the invention provides a charging control method and device and a vehicle, and belongs to the technical field of automobiles. The method comprises the following steps: performing low-voltage power-on on a vehicle in response to a charging trigger request; determining the current residual electric quantity of a power battery of the vehicle and the target electric quantity required by a user; and under the condition that the current residual electric quantity of the vehicle is smaller than the target electric quantity required by the user, high-voltage power-on is carried out, and charging is started. By using the charging control method and device and the vehicle provided by the invention, whether a charging demand exists or not can be considered according to the relationship between the current residual electric quantity of the vehicle and the target electric quantity, high-voltage power-on is performed only when the charging demand exists, and high-voltage power-on is not performed when the charging demand does not exist, so that the resource utilization rate is improved, and the charging efficiency is improved. And resource waste is reduced.

Description

technical field [0001] The embodiments of the present application relate to the technical field of automobiles, and in particular, to a charging control method, device, and vehicle. Background technique [0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources to form new technologies and structures. Among the new energy vehicles, the vehicles belonging to hybrid and pure electric vehicles have added the battery pack charging function, and added the reservation charging function according to the driving time and usage habits of different drivers. [0003] In the prior art, after the vehicle receives the reservation charging request input by the user, it will automatically power on after a period of time, and then determine whether the current power of the vehicle meets the target power required by the user, and if so, control the vehicle to power off. , if not satisfied, control the vehicle to charge. [0004] However, when the c...
