Finding Attractive Electric-Vehicle-Charging Locations with Photovoltaic System Integration

Abstract

The rise of electric mobility poses a challenge and an opportunity for the housing industry to provide charging infrastructure. The housing industry can take advantage of its large roof areas to install photovoltaic (PV) systems and use the electricity generated to charge electric vehicles. This study explores how the charging demand can be allocated to specific locations based on socio-economic parameters and determines whether PV integration is economically viable for EV charging. Two models are used, one with extensive spatial and traffic data to determine the charging demand for over 300 locations, and another with a time-series-based approach for four specific locations to analyze the seasonal dependencies. The results indicate that PV integration is economically advantageous when electricity purchase prices exceed 0.15 EUR/kWh. Higher electricity prices can lead to significant additional profits through PV integration. Slow charging and charging during the day are beneficial, as they increase self-consumption, making PV systems economically viable. However, fast-charging infrastructure should be combined with PV storage systems for effective PV integration.

A Sustainable Solution for Urban Transport Using Photovoltaic Electric Vehicle Charging Stations: A Case Study of the City of Hail in Saudi Arabia

“…The total cost of ownership of an EV is already less than that of a vehicle with a comparable internal combustion engine in some auto categories [34]. Dörre et al [35] investigated the feasibility of PV integration from an economic standpoint and looked into how the demand for EV charging may be distributed among different places (WIRO GmbH) in Germany according to socioeconomic factors. The findings demonstrate that PV systems can be integrated with infrastructure for charging and generating revenue.…”
