Embodiment 1

[0035] figure 1 , figure 2 A preferred implementation of the electric vehicle charging control method of the present invention is shown.

[0036] In the electric vehicle charging control method of this embodiment, the communication between the battery management system and the charging pile is completed, the basic performance parameters of the charging pile are obtained, the real-time temperature of the battery, the real-time ambient temperature of the battery, the total power of the battery system, and the battery temperature rise characteristic table ( Laboratory measured value), the temperature difference of each temperature point of the battery box, the pressure difference of each battery connected in series and other basic data acquisition, and interact with the UI interface of the remote control client, so that the user can choose different charging according to the current battery usage status method and charging capacity, or different charging methods and charging ti...

Embodiment 2

[0051] Such as image 3 As shown, the main difference between this embodiment and Embodiment 1 is that the motor vehicle charging control method of this embodiment further includes step (9): the battery management system uploads the charging statistical data to the server of the big data platform.

[0052] Among them, the charging statistical data includes the battery charging amount in the cycle interval of the battery charging amount, the number of times the battery is charged, the average temperature during the charging process, the charging method and the charging demand parameters.

[0053] The motor vehicle charging control method in this embodiment uploads the charging statistical data during the charging process to the server of the big data platform, and later can provide strong support for charging control scheme optimization and charging preference analysis through big data analysis.

[0054] The rest of this embodiment is the same as Embodiment 1 above.

Embodiment 3

[0056] This embodiment provides a charging control system for an electric vehicle.

[0057] Such as Figure 4 As shown, an electric vehicle charging control system includes a battery management system 10, a battery data acquisition unit 20 connected to the battery management system 10, a charging pile data acquisition unit 30 connected to the battery management system 10, and a battery management system connected to the battery management system 10. The system 10 communicates with the remote control client 40 .

[0058] Wherein, the battery management system 10 includes a central processing unit 11 and a communication unit 12 connected to the central processing unit 11; the battery data collection unit 20 and the charging pile data collection unit 30 are connected to the central processing unit 11, and the remote control client 40 passes through The communication unit 12 is connected to the central processing unit 11 .

[0059] Preferably, the central processing unit 11 is a...

Abstract

The invention relates to a charging control method and system for an electric vehicle. Through the battery management system and the charging pile to complete the communication, obtain the basic performance parameters of the charging pile, through the acquisition of the basic battery data, and interact with the remote control client, so that the user can choose different charging methods and charging power according to the current battery usage conditions, Or different charging methods and charging time, meet the needs of users from different dimensions, combine the charging needs of users and the state parameters of the battery system at that time, estimate the temperature rise of the battery under different charging schemes, and the time required to complete the charging capacity may be completed. The charging capacity and other information, and let the user know when the charging demand can be completed; the user obtains the relevant charging information through the remote control client, and finally selects the charging method according to his own charging demand. Finally, according to the user's charging demand parameters, combined with the real-time status of the battery variable to complete the optimization of the current curve during the charging process, thereby controlling the entire charging process.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging, in particular to an electric vehicle charging control method and system. Background technique [0002] With the rapid development of new energy electric vehicles in recent years, more and more electric vehicles are used in society.
