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.
Taken together, the skeleton or main body of the charging pile meets the requirements of strength and safety margin. The anti-dumping stability of the charging pile refers to the ability of the pile with parts to maintain its original equilibrium state in the process of moving.
In general, the charging pile works in a static state and is fixed at the bottom during transportation; therefore, we replaced the four wheels with mass blocks for simplification. Furthermore, the overall mesh size of the model has been controlled around 20 mm by mapping mesh division.
Mobile charging piles impact the power grid of the access system when charging, which indicates the possibility of new installation and layout rearrangement of the original power gird should be taken into consideration. Furthermore, the investigation of the intelligent regulation function of the power grid remains challenging.
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.
CATIA was used to model the pile structure, in which four columns were made of angle steel and the rest brackets were made of square steel. Four wheels were designed at the bottom to facilitate the movement of charging piles. Each functional module of the charging pile is arranged in the modular partition.

First, the ambient air (T 1, P 1) is compressed by the electric power generated from the renewable energy available for storage.Once it is compressed, the pressure and temperature of the compressed air drastically rise (T 2, P 2).This compressed air with an extra high temperature (more than 1000 °C) is not practical to store inside the pile foundation.
