Sunwin Charging Pile 3C Testing Equipment

In the key link of charging pile quality inspection, the charging pile 3C testing equipment developed by Sunwin stands out with its outstanding functional features, providing a solid guarantee for the performance evaluation and quality control of charging piles.

1. High-precision parameter measurement: Equipped with advanced high-precision sensors, the voltage measurement accuracy can reach ±0.05%, and the current measurement accuracy can reach ±0.1%, which can accurately capture the slight changes in the electrical parameters of the charging pile. When testing a charging pile with an output voltage of 220V, the equipment can detect a voltage deviation of 0.11V; for a charging pile with an output current of 32A, the measurement error can be controlled within ±0.032A, providing a reliable data basis for the performance evaluation of the charging pile.

2. Comprehensive testing of charging functions: It can simulate the charging needs of different types of electric vehicles, and conduct detailed tests on various charging modes such as constant current charging, constant voltage charging, and trickle charging of charging piles. In constant current charging mode, it can accurately monitor whether the charging current is stable at the set value with a very small deviation range; in the constant voltage charging stage, it can accurately measure whether the voltage maintenance and the gradual attenuation process of the current meet the standard. In addition, it can also comprehensively detect whether the charging start and stop functions of the charging pile are normal, and whether the power adjustment during the charging process is accurate, to ensure that the charging pile can operate stably in various charging scenarios and meet the charging needs of users.

3. In-depth testing of communication functions: It has powerful communication function testing capabilities and can deeply detect the communication protocol between the charging pile and the electric vehicle. It supports a variety of common communication protocols, such as CAN bus, TCP/IP, etc. It can simulate the communication module of the electric vehicle, interact with the charging pile for various commands, verify whether the charging pile can correctly receive and parse the charging demand, battery status and other information sent by the vehicle, and check whether the charging parameters, fault information, etc. fed back by the charging pile to the vehicle are accurate. By comprehensively evaluating the strength, stability, transmission rate, etc. of the communication signal, it ensures that the communication between the charging pile and the electric vehicle is unimpeded, and avoids charging abnormalities or safety accidents caused by communication failures.

4. Protection function simulation verification: In order to ensure the safety of charging piles under various abnormal conditions, the device can simulate various fault scenarios such as overvoltage, undervoltage, overcurrent, leakage, short circuit, etc., and strictly verify the protection function of the charging pile. When simulating overvoltage, the device can gradually increase the input voltage to a certain proportion (such as 120%) of the rated voltage of the charging pile to observe whether the charging pile can start the overvoltage protection mechanism within the specified time (such as 100 milliseconds) and cut off the charging output; for leakage fault simulation, the device can inject a small leakage current into the output circuit of the charging pile to detect whether the leakage protection device can act quickly, providing reliable protection for the safe operation of the charging pile.

5. Wide compatibility and adaptation: It has excellent compatibility and can adapt to charging piles of different brands and models and various types of electric vehicles. Whether it is a charging pile that meets national standards or a device that adopts international standards or enterprise-defined standards, it can be effectively tested. The device has a rich built-in interface library and protocol analysis module, which can automatically adjust the detection parameters and processes according to different devices under test to achieve seamless docking. For some new energy vehicle brand exclusive charging piles that use special charging interfaces or communication protocols, Sunwin equipment can quickly realize their compatibility detection through software upgrades or hardware expansion modules, providing a convenient one-stop detection solution for charging pile manufacturers, testing agencies and operation and maintenance departments, greatly improving the detection efficiency and versatility of equipment.

6. Automated detection process and report generation: With an automated detection process, operators only need to simply set the detection items and parameters on the device operation interface, and the equipment can automatically complete various detection tasks for the charging pile according to the preset program, reducing human operation errors and detection time. After the detection is completed, a detailed detection report can be automatically generated. The report content covers the basic information of the charging pile, the measurement results of various electrical parameters, the charging function test status, the communication function evaluation, the protection function verification results, and the compatibility test conclusions. The report format is standardized and the content is detailed. It can be directly used for product quality assessment, certification application or archiving records, providing users with a comprehensive and intuitive presentation of detection results, which is convenient for users to accurately judge and analyze the quality status of the charging pile.
