By leveraging clean energy and implementing energy storage solutions, the environmental impact of EV charging can be minimized, concurrently enhancing sustainability.
With the promotion and popularization of new energy vehicles, the modeling and prediction of charging pile usage and allocation have garnered significant attention from governments and enterprises.
Several approaches [50] have been suggested to determine the remaining useful life(RUL) of the lithium battery based on the charge and discharge characteristics of the battery.These findings indicate that there are basically three sorts of methodologies for predicting the RUL of lithium batteries: physical models, data-driven methods, and hybrid model-based

The authors propose a two-stage sequential configuration method for energy storage systems to solve the problems of the heavy load, low voltage, and increased network loss caused by the large number of electric vehicle (EV) charging piles and distributed photovoltaic (PV) access in urban, old and unbalanced distribution networks.

The charging event dataset includes the EV ID, charging pile ID, start time, end time of each charging event, and energy demand during this period, as listed in Table 3. The charging station dataset includes the charging station ID, charging station latitude and longitude, charging station type, charging pile type, and charging pile power rate, as listed in Table 4 .
These data are from 60 kW and 120 kW fast charging piles. The utilization rate of the corresponding charging pile in Profile II is the highest, with the average power reaching 44.87 kW, while that in Profile VI is only 15.42 kW. The average power and Corr PV-EV of the load profiles are marked below the profiles number in Table IX.
A two-stage model has also been proposed to optimize EV charging and the selection of charging piles by effectively grouping the distribution pattern of EV charging demand and various types of EVs, and by minimizing the annual investment and electricity purchasing costs of charging piles [ 34 ].
In current practice, the determination of the number of EV charging piles in office building parking lots is generally based on an area-based empirical estimation method. This method utilizes the lower limit of the range of charging facilities prescribed in the relevant design standards.
This can be attributed to the inadequate charging capacity in the later years of the design period when the number of charging piles is limited.
As the number of charging piles increases gradually, the satisfaction rate of charging demand improves progressively, but the problem of idle charging piles is aggravated in the early years of the design period.
In summary, an effective charging pile configuration scheme should consider both the average utilization rate of charging facilities and the average satisfaction rate of charging demand. Furthermore, the degree to which these two indicators are high in tandem reflects the quality of the configuration scheme.
Taking the average utilization rate of charging facilities and the average satisfaction rate of charging demand as the objective functions, the distribution of the optimal number of piles is obtained with the genetic algorithm. The benefits of the configuration method are also explored under the building demand response process.
