1 Model Variables In order to analyze the ratio of new energy vehicles to charging piles more accurately, we narrowed the scope of the model as much as possible.
The weight of the safety protection module, human–computer interaction module, charging gun and its interface components, core control module, and data communication and monitoring module of the charging pile were 2, 8, 22, 12, and 6 kg, respectively.
The charging pile adopts a frame structure with welding and riveting process. According to environmental requirements, aluminium alloy, steel, and other materials are generally selected.
The simple instalment of mobile charging piles benefits for its convenient layout, while dynamic arrangements of those charging piles through mobile mode make up for the insufficient number of fixed charging piles, which meets the growing charging demand under the increasing popularity of electric vehicles.
The structured shape of the charging pile is fixed, so the method to improve the stability is mainly to adjust the position of gravity centre of the box, or to increase the size of the bottom support surface of the box, on the premise of not changing the overall structure size. Mobile charging piles are fixed by wheel support.
Our results have demonstrated that the maximum deformation value of the structure is 3.07 mm, and the maximum stress is 134.41 MPa, which is within the safety range of the selected materials. In addition, the gravity centre of the charging pile is located at the bottom of the structure, and thus the stability meets the requirements.

With the development of new energy vehicles, charging piles and charging stations have been continuously constructed. Compared with research on new energy vehicles, especially pure electric vehicles, there are relatively few researches on charging piles.
If the growth rate of private charging piles or public charging piles can be maintained, then the ratio of vehicles to piles in an ideal state will be 1:1. It will be realized in 2030, and the charging of new energy vehicles will become easier and easier.
The research simulation predicts that in the next 10 years, the ratio of vehicles to piles of new energy vehicles in China will become lower and lower. If the growth rate of private charging piles or public charging piles can be maintained, then the ratio of vehicles to piles in an ideal state will be 1:1.
In order to meet this increasing demand, public charging piles will enter a rapid development channel. The ratio of vehicle-to-pile is reasonable, and different people have different understandings. At present, some departments have positioned the ideal vehicle to pile ratio as 1:1.
