Cost reduction of energy storage: The cost of energy storage batteries constitutes a significant proportion of the cost of PV-ES-I CS systems at various scales. Therefore, it is recommended that governments adopt measures to reduce the cost of energy storage, which is crucial for the development of PV-ES-I CSs.
With the development of the photovoltaic industry, the use of solar energy to generate low-cost electricity is gradually being realized. However, electricity prices in the power grid fluctuate throughout the day. Therefore, it is necessary to integrate photovoltaic and energy storage systems as a valuable supplement for bus charging stations, which
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.

Most solar energy storage systems have a lifespan between 5 and 15 years. However, the actual lifespan depends on the technology, usage, and maintenance. Lithium-ion batteries generally have a longer lifespan (around 10-15 years), while lead-acid batteries may need replacement after 5-10 years (Dunlop, 2015).
