The charging piles configured in the planning scheme are also fast charging piles with uniform specifications. According to , the land prices are classified into seven levels based on the distance from the downtown area. The highest price level is located in the downtown area (approximately 5420 USD/m 2), while the lowest level is found at the urban periphery
Recently, the operation of electric charging stations has stopped being solely dependent on the state or centralised energy companies, instead depending on the decentralization of decisions made by the operators of these stations, whose goals are to maximise efficiency in the distribution and supply of energy for electric vehicles. Therefore, the

Donald Trump''s reelection as President will impact the energy industry, but maybe not as expected. Energy, trade, regulatory, fiscal and monetary policy may be at odds.
New energy storage charging piles are reduced every year; The investment cost of charging stations is high and the equipment utilization rate is low, resulting in a waste of charging resources. The application of new charging piles, charging robots and other automatic charging devices with automatic charging functions is one of the solutions to improve the utilization rate

The integration of an ESS in the EV charging station can not only reduce the charging time, but also reduces the stress on the grid. A suitable comparison among the various energy storage technologies applicable for this scope is among electrochemical storages (batteries), electromechanical storages (flywheels) and electrostatic storages (ultra-capacitors).
In addition, installing energy storage systems (ESS) in a GCS is recently considered as one promising solution to accommodate the intermittent renewable energy sources and uncertain EV charging demand .For example, it is pointed out in that the integration of PV panels and ESS in charging stations can relieve the pressure on the distribution network
The photovoltaic panels will convert the solar energy into electricity; meanwhile, the electricity will be stored in the battery units for further use. Drivers can use the solar power charging piles inside to charge their electric cars. And the whole process would take some 3.5 hours, which is similar to that of other normal charging piles.
EV is the combination of different technologies, which includes multiple engineering fields such as mechanical, electrical, automotive, chemical engineering and electronics (Chan, 1993; Sharma et al., 2020) the combination of different technologies, the overall efficiency and fuel consumption of the EV is reduced which makes it more efficient in
