The Photovoltaic-energy storage-integrated Charging Station (PV-ES-I CS) is a facility that integrates PV power generation, battery storage, and EV charging capabilities (as shown in Fig. 1 A). By installing solar panels, solar energy is converted into electricity and stored in batteries, which is then used to charge EVs when needed.
