AC Charging Pile Automatic Testing System Solution

Industry Background 

Automatic testing of AC charging piles refers to the use of automated equipment to conduct a series of tests on AC charging piles to 

evaluate their response performance and stability under different charging sequences, as well as the timeliness and reliability of safety 

protection in case of charging abnormalities. 

In recent years, with the advancement of new energy vehicle technology and the reduction in prices, the number of new energy vehicles

in China has continued to increase. This growth trend has driven the development of the electric vehicle charging pile industry. 

It is estimated that the number of public charging piles in China will increase to 6.543 million by 2025. 

The government has successively introduced multiple policies to support innovation in charging pile-related technologies, models, 

and mechanisms. For instance, in 2020, the Chinese government first proposed the concept of "new infrastructure", which includes 

the construction of charging piles and battery swap stations. These policies not only promote the development of the charging pile 

industry but also provide clear development directions and goals for it. 

Against the backdrop of rising sales of new energy vehicles, a high vehicle-to-pile ratio, and government support, the construction 

of charging piles in Europe and the United States is expected to accelerate, presenting significant opportunities for Chinese charging 

piles to go global.In recent years, the new energy vehicle industry in the European Union and the United States has developed rapidly, 

but the vehicle-to-pile ratio gap is much larger than that in China. In 2023, the public vehicle-to-pile ratios in the European Union and 

the United States were 13:1 and 24:1 respectively, while in China it was approximately 7:1.

The development of new energy vehicles has brought about a huge demand for AC charging piles, and the safety and reliability of 

charging piles have also received increasing attention.  Against this background, the AC charging pile testing industry has a promising 

development prospect. With the support of policies, the expansion of the market, the advancement of technology, and the synergy of

the industrial chain, as well as the development of electric vehicles in domestic and international markets, this industry will continue 

to contribute to the healthy development of the electric vehicle industry.
