FT dc charging pile, pile module, car charger automatic test system is faith based on the full understanding of the charging pile industry, as well as the development of power electronic test equipment industry for many years experience, developed a set of open can be customized according to customer's requirements, general functional test automation solutions,

The system adopts FAITH's high performance FT8000 automatic acquisition and control system and Faith's AC-DC and high-power power load products, integrates virtual instrument, power testing, network communication, BMS, grid-connected feedback and other technologies, and is suitable for the functional test of DC charging pile. The system has strong superiority in technical level, production efficiency and quality control.

The system is designed based on the open hardware and software architecture, which can expand the hardware flexibly and set up the test program quickly. The system can be flexibly configured according to customer requirements; The rich basic test items of the system greatly improve the usability of the system, and try our best to provide users with a general, flexible and standardized automatic test system solution for DC charging pile.

System Features:

Versatility: It can flexibly meet the requirements of functional testing and aging testing of various types of products such as charging pile, charging pile module and vehicle charging machine

Expansibility: new products only need to change the fixture and edit the corresponding test software

Accuracy and reliability: The main hardware adopts Faith's high-level independent products, including all kinds of power supplies, all kinds of loads, series of test boards, etc., to ensure the performance and quality of the system

Safety: Good anti-freeze system, to ensure that operators and products are not hurt

Ease of use: Easy to operate without manual judgment

Economy: effectively save personnel input and reduce unit test cost

System Architecture:

The system uses the NXI bus virtual instrument IO board card and various instruments and equipment (AC power supply, electronic load, power analyzer, oscilloscope, DMM, CAN card, etc.) independently developed by Faith. Virtual instrument technology is used to test relevant functions, and the test results are saved to the database. All the test items are directly controlled by the computer, without manual operation of the instrument, to achieve a safe, easy to use, accurate, efficient effect.

Software architecture :

The software adopts modular design, including user management, data management, testing, system configuration and other four functional modules, through the main interface can enter each module.

User management module: to ensure system security and system parameters are not maliciously modified, different users have different login names and permission Settings. The permission setting is divided into three levels: engineer, technician and operator. The operator has the basic operation function and disables various setting functions. In addition to all the functions of the operator, the technician also has limited permission to modify parameters; Engineers can operate all functions, add or delete accounts.

Data management module: record all the test data and store it in the specified storage path, which is convenient for customers to track and analyze the production of products, and provide a strong basis for the management to improve the production line reasonably. It can be connected to the MES system for centralized data access. Various reports and statistical functions can be customized according to customer requirements.

Test module: including voltage, current, waveform, hardware control, self-test function, bar code function, printer control and other functions.

System configuration module: can set the test items, test limits and other configuration items.

Software features :

The operating system is Windows XP, based on Labview 2010 software platform;

Can add, modify, delete user information, user information is saved in the database;

According to customer requirements to save data and generate a specified format of reports;

CAN carry out CAN communication analysis according to the specific content of customer's agreement;

After the bar code scanner can be configured, the program can automatically enter the user - defined bar code and save to the database.
