The research results indicate that during peak hours at the charging station, the probability of electricity consumption exceeding the storage battery's capacity is only 3.562 %. After five years of operation, the charging station has saved 5.6610 % on electricity costs.
As shown in Fig. 1, a photovoltaic-energy storage-integrated charging station (PV-ES-I CS) is a novel component of renewable energy charging infrastructure that combines distributed PV, battery energy storage systems, and EV charging systems.
This demonstrates that using energy storage facilities at the charging station can effectively alleviate the grid's load during peak electricity consumption. Fig. 8. Daily electricity requirements for electric vehicles during peak hours at charging stations.
The total investment cost of the energy storage system for each charging station can be calculated by multiplying the investment cost per kWh of the energy storage system by the capacity of the batteries used for energy storage. Table 4. Actual charging data and first-year PV production capacity data.
The results provide a reference for policymakers and charging facility operators. In this study, an evaluation framework for retrofitting traditional electric vehicle charging stations (EVCSs) into photovoltaic-energy storage-integrated charging stations (PV-ES-I CSs) to improve green and low-carbon energy supply systems is proposed.
Strong support for the sustainable development of EV charging infrastructure can be provided by addressing issues such as charging station capacity matching, charger quantity distribution, and charging pile power design through scientific capacity planning and in-depth research.
