Detailed ways

As shown in Figure 1, it is a block diagram of a robot-based charging system.

A robot-based charging system for automatically charging an electric vehicle to be charged includes a robot 10 connected to a power source and a charging management module 20 connected to the electric vehicle.

The charging management module 20 includes a communication module 201 for connecting with an electric vehicle, a control instruction output module 203 and a charging mode sending module 205 .

The communication module 201 is also used for communicating with the electric vehicle to obtain the location of the electric vehicle and the battery information of the electric vehicle.

The communication module 201 plays an information interaction role between the charging management module 20 and the electric vehicle, and is used to obtain information of the electric vehicle, specifically including location information of the electric vehicle and battery information of the electric vehicle. Since there is no fixed charging position of the electric vehicle in the charging system based on the robot, in order for the robot 10 to accurately find the electric vehicle when the electric vehicle is charging, the communication module 201 needs to obtain the location information of the electric vehicle. Therefore, after acquiring the position information of the electric vehicle, the robot 10 can find the charging target through automatic routing. The purpose of obtaining the battery information of the electric vehicle is to send a charging instruction to the robot 10, wherein the charging instruction includes charging time, charging mode and charging amount.

The charging mode sending module 205 is connected with the communication module 201, and is used for generating a charging mode instruction for the robot 10 to the electric vehicle according to the battery information. Since the charging modes of batteries produced by different models and different manufacturers are different, the communication module 201 is required to obtain the charging mode information of the electric vehicle battery, so as to avoid damaging the battery due to inconsistent charging modes and affecting the service life of the battery.

The control command output module 203 is connected to the communication module 201 and is used for generating a charging target command and a charging target position command of the robot 10 according to the position of the electric vehicle. The control command output module 203 is used for generating corresponding control commands from the battery information and the position of the electric vehicle acquired by the communication module 201 . For example, the communication module 201 sets the coordinate system based on the current position, and then acquires the position coordinates (x, y, z) of the electric vehicle, and at the same time acquires the position coordinates (m, n, g) of the robot 10, and then according to the coordinates of the two Through calculation, send out the control command of the distance and direction that the robot 10 advances towards the electric vehicle. Therefore, after receiving the control command output by the control command output module 203 , the robot 10 automatically searches for the charging target according to the forward distance and direction corresponding to the control command.

Specifically, the communication module 201 communicates with the electric vehicle to obtain the state of charge of the electric vehicle, the actual capacity of the battery, the remaining capacity of the battery, the depth of discharge, and the location information of the electric vehicle.
