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.
What are the advantages of mobile charging piles?
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.
How to improve the stability of a mobile charging pile?
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.
What is the maximum deformation value of a charging pile?
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.
How many electric vehicle charging piles are there in China?
In 2006, the first electric vehicle charging pile station was built in Shenzhen, while the accelerated development of the field has been witnessed since 2014. By the end of 2020, the number of public and private charging piles was 1.681 million, while the ratio of vehicle to pile was 3:1.
