Applying the characteristics of energy storage technology to the charging piles of electric vehicles and optimizing them in conjunction with the power grid can achieve the effect of peak-shaving and valley-filling, which can effectively cut costs.
The integration of charging stations (CSs) serving the rising numbers of EVs into the electric network is an open problem. The rising and uncoordinated electric load because of EV charging (EVC) exacts considerable challenges to the reliable functioning of the electrical network [22].Presently, there is an increasing demand for electric vehicles, which has resulted in

Charging pile energy storage system can improve the relationship between power supply and demand. Applying the characteristics of energy storage technology to the charging piles of electric vehicles and optimizing them in conjunction with the power grid can achieve the effect of peak-shaving and valley-filling, which can effectively cut costs.
Electric vehicle charging piles are different from traditional gas stations and are generally installed in public places. The wide deployment of charging pile energy storage systems is of great significance to the development of smart grids. Through the demand side management, the effect of stabilizing grid fluctuations can be achieved.
Less charging piles, higher utility Assume that the vehicles have a battery size of 400 km. According to Fig. 3, the area needs 20 charging piles without V2V charging (i.e. the total charging capacity of all stations, γ, is 40 km per 2 min; while the capacity of each individual charging pile, μ, is 2 km per 2 min).
Researchers also predict that the idle rate of charging piles will be high . At the same time, carmakers are equipping electric vehicles with increasingly larger batteries in response to the range anxiety and the shortage of charging piles. However, larger batteries are more expensive.
Major economies ambitiously install charging pile networks, with massive construction spending, maintenance costs, and urban space occupation. However, recent developments in technology may significantly reduce the necessary charging capacity required by the system.
The construction, maintenance, and management of these charging piles can be even more expensive, as they will likely be in urban areas where demands are high, and land is scarce. Researchers also predict that the idle rate of charging piles will be high .
