Solution for Multi-Channel Aging Test System of AC Charging Stands

I. Industry Background:

The aging test of AC charging stands refers to a series of tests conducted on electric vehicle AC charging stands to evaluate their performance

and reliability during long-term operation. With the rapid development of the electric vehicle market, AC charging stands, 

as an important component of the charging infrastructure for electric vehicles, have received increasing attention for their stability and safety.

In China, the government has provided strong support for the new energy vehicle industry, promoting the rapid development of electric 

vehicles and charging facilities. According to my training data, the following are some key points of the industry background of AC charging 

stand aging tests:

1. Policy Support: The Chinese government's "New Energy Vehicle Industry Development Plan (2021-2035)" proposes to accelerate the

construction of charging infrastructure, optimize the layout of charging stands, and improve charging convenience and safety. 

This provides policy basis for the development  of the AC charging stand aging test industry.

2. Market Size: With the increase in the number of electric vehicles, the market demand for charging stations continues to grow. 

According to predictions，the market size of charging stations in China will continue to expand in the coming years, 

which brings a broad market space for the AC charging stand aging test industry.

3. Technological Progress: The development of AC charging stand aging test technology helps improve the performance and

reliability of charging stands. 

By simulating different working conditions such as long-term operation and extreme temperatures, the durability and 

stability of the stands are tested, thereby enhancing the overall quality of the charging stands.

4. Industry Standards: To ensure the quality and effectiveness of AC charging stand aging tests, it is necessary to establish 

relevant industry standards. 

This includes specifications for testing methods, testing equipment, testing environment, etc., to ensure the consistency

and reliability of the test results.

5. Industry Chain Collaboration: AC charging stand aging tests involve multiple links such as testing equipment, testing methods, 

data analysis, etc., 

and require the collaboration of related industries. As the industry develops, more and more enterprises are beginning to

pay attention to this field, which is expected to form a good industrial ecosystem.

In conclusion, the AC charging stand aging test industry in China has a promising development prospect. 

With policy support, market expansion，technological progress, and industry chain collaboration,

this industry will continue to contribute to the healthy development of the electric vehicle industry. 

II. Application Requirements:

The connection of the load enables 20-channel (customizable and scalable) series testing. It can also achieve aging of 

any single channel or series aging of multiple channels.

The aging rack and the load are separated. The load part can be used independently and applied to the testing of 

other products. The load can be selected as a power resistor load or a feedback energy-saving load. 

III. Solution:

The AC charging pile aging test system developed by Ruijie Intelligent is specifically designed for electric vehicle charging piles. 

It aims to develop a simple and easy-to-operate AC charging pile aging test stand based on user requirements.

The system adopts an open hardware and software architecture, providing Ruijie Company's feedback-type AC resistance load,

AC pile guiding device, system control switching unit, and industrial computer and other measurement and testing equipment. 

The equipment uses energy-saving loads,which can transform the output electrical energy of the product to be tested

and then return it to the power grid, achieving energy conservation and environmental protection, with an energy feedback

rate of about 90%.
