Abstract

This study assesses the feasibility of photovoltaic (PV) charging stations with local battery storage for electric vehicles (EVs) located in the United States and China using a simulation model that estimates the system's energy balance, yearly energy costs, and cumulative CO2 emissions in different scenarios based on the system's PV energy share, assuming silicon PV modules, and 5 kWh of storage capacity. Results show that systems located in commercial or office parking lots and used for charging EVs during working hours can be a feasible solution in all locations from a technical, financial, and environmental perspective in comparison with not only gasoline-fueled vehicles but also with grid-only charging. PV shares of 50% and 75% are achievable in all locations with PV array sizes in the order of 1–1.5 kWp , whereas a 100% PV share is possible but might result in high system costs. Scenarios with PV charging and local storage show emissions reductions of 60%–93% in the USA and 28%–93% in China compared with a gasoline-fueled vehicle.
