[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] Example 1 Reference Figure 1 A charging pile debugging and testing system based on the TCP communication protocol is proposed. The system consists of a local control terminal module, a data debugging and testing module, and a charging pile. The data debugging and testing module is installed in the charging pile to ensure effective and comprehensive acquisition of various information data of the charging pile and to ensure the safe and stable operation of the charging pile.

[0027] The data debugging and testing module features network communication, command parsing, debugging command execution, and test parameter acquisition capabilities. As a TCP server, it establishes a stable and reliable TCP connection with the local control terminal module, ensuring data transmission is loss-free and error-free. It also performs detailed parsing of received commands from the local control terminal module, identifying the specific operational requirements corresponding to different commands. Furthermore, based on the parsed commands, it precisely controls the charging pile to perform corresponding debugging tasks and acquires various key parameters during charging pile operation, primarily including operating status parameters, charging performance parameters, environmental parameters, and fault diagnosis parameters.

[0028] Specifically, this system includes the following functions: 1. Remote communication charging pile: The communication between the local control terminal module and the data debugging and testing module adopts the reliable transmission protocol TCP of the network transmission layer. The local control terminal module is the TCP client and the data debugging and testing module is the TCP server. The connection failure has a reconnection mechanism.

[0029] 2. Supports multi-parameter detection: The local control terminal module detects the performance parameters of the charging pile in real time by issuing preset commands, so as to analyze the operating status of the charging pile and discover potential problems. The preset commands are expandable. The preset commands include debugging commands and detection commands. The debugging commands are used to verify the basic functions of the charging pile to ensure that they can be implemented accurately, and the detection commands are used to obtain various performance parameters of the charging pile during operation. The detection parameters mainly include the following: the real-time working status of the charging pile, clarifying its idle, charging, or faulty state; the connection status of the charging gun, determining whether the charging gun is correctly inserted; the charging pile's required voltage, output voltage, required current, output current, and charging capacity, to detect the stability of power transmission during charging, while also acquiring the charging output power value, analyzing the dynamic response characteristics of the charging power, and evaluating the power distribution status of the charging pile; and collecting information on the internal temperature of the charging pile and the temperature and humidity of its surrounding environment to understand the potential impact of environmental factors on the operation of the charging pile, which helps to determine its stability and reliability under different environmental conditions.

[0030] 3. Basic Function Debugging: The data debugging and testing module parses preset commands to debug the charging pile and feeds the debugging results back to the local control terminal module for technicians to view. Debugging commands include time synchronization, starting charging, stopping charging, and setting power. The time synchronization command not only ensures that all relevant equipment and systems maintain consistent time but also meets debugging requirements under different test conditions.

[0031] 4. Fault diagnosis: Periodically monitor and diagnose faults, and handle charging pile faults and problems in a timely and accurate manner.

[0032] When the charging pile is in a faulty operating state, the data debugging and detection module is used to obtain detailed information such as the fault code, the time of the fault, and the changes in key parameters before and after the fault, so as to provide detailed basis for quickly locating the cause of the fault and carrying out maintenance.

[0033] Example 2 Reference Figure 2 This embodiment provides a charging pile debugging and testing method based on the TCP communication protocol. The charging pile debugging and testing method based on the TCP communication protocol in Embodiment 1 includes the following steps: Step 1: After the charging pile debugging and testing system based on the TCP communication protocol is started, the local control terminal module first connects to the data debugging and testing module through the IP address and port number, where the IP address and port number are consistent with the IP address and port number of the network to which the charging pile is connected; then the data debugging and testing module listens to the IP address and port number set by the local control terminal module and sends a connection success signal back to the local control terminal module. Step 2: The local control terminal module waits for the connection result. If successful, it enters the data interaction stage with the data debugging and detection module. If the connection fails, it will reconnect after 20 seconds until the connection is successful.

[0034] Step 3: The local control terminal module sends preset instructions to the data debugging and testing module; the preset instructions include debugging instructions and testing instructions. The debugging instructions are used to verify the basic functions of the charging pile to ensure that they can be accurately implemented, and the testing instructions are used to obtain various performance parameters of the charging pile during operation. Step 4: The data debugging and detection module receives and processes preset instructions, sends the queried charging pile operation data and debugging feedback results to the local control terminal module, and periodically reports the detailed fault information of the charging pile to the local control terminal module. Step 5: The local control terminal module analyzes and processes the acquired information data, specifically including: Monitoring the real-time operating status of charging piles can record the specific time it takes for a charging pile to transition from one state to another, such as the time it takes to enter charging mode from idle mode, or the time it takes to transition from charging mode to fault mode. By analyzing the transition time between idle and charging modes, it can be determined whether the charging pile's start-up and stop response data are normal. Simultaneously, the duration of the charging pile in a fault state can be statistically analyzed. For example, if the duration of a charging pile in a fault state is too long, it indicates that the fault handling mechanism is not efficient enough.

[0035] Analysis of the internal temperature and humidity of the charging pile: During the charging process, the internal temperature of the charging pile may be too high due to overload of the power module and low efficiency of the cooling fan, which may cause module failure and affect charging. Excessive humidity may cause electrical components to become damp and short-circuit.

[0036] Plot the curves of demand voltage, output voltage, demand current, and output current over time. Calculate the fluctuation range of the output voltage and evaluate the stability of the charging pile's output voltage. Compare the fluctuation range with a preset fluctuation threshold. If the fluctuation range exceeds the threshold, the output voltage is considered unstable. During charging, the output voltage fluctuation range should be within a certain allowable range to avoid overcharging or charging interruption due to voltage instability. If the output voltage is too high, it indicates input instability or an overvoltage fault. If the output voltage is too low, it indicates insufficient supply leading to low charging efficiency. Output voltage fluctuation. It is usually defined as the difference between the maximum and minimum values ​​of the output voltage within a specific time period, and the calculation method is as follows:

[0037] Wherein, U1 is the output voltage value at the first sampling time, U2 is the output voltage value at the second sampling time, and U3 is the output voltage value at the third sampling time. This is the output voltage value at the nth sampling time.

[0038] By comparing the matching condition of the demand current and the output current, it can be determined whether the output current can respond to the demand current in a timely and accurate manner: If the output current consistently or frequently exceeds the required current, the analysis indicates that the required current fluctuates frequently, resulting in errors in data acquisition. Under normal circumstances, an overcurrent event will immediately stop charging to prevent battery damage. It is extremely rare for the overcurrent protection mechanism of the charging station to malfunction, causing the output current to be uncontrollable.

[0039] When the output power of a charging pile is changed by issuing a power adjustment command, the response time of the charging pile and the output power value after setting the output power are analyzed to evaluate the dynamic response characteristics of the charging pile's charging power. This ensures that the charging pile can adjust the power in a timely and accurate manner according to the demand. If the error between the set power value and the adjusted power value is large, the efficiency of the charging pile's power allocation strategy will be further improved.
