Long-term test of an electric vehicle charged from a photovoltaic carport

Abstract

The article includes experimental investigations of electricity consumption over a distance of 30,000 km by a small city electric vehicle. During that time period, the vehicle was charged in most cases from a photovoltaic carport with a peak power of 3 kWp. The analyses include vehicle mileage and the number of times the battery has been charged during 5 years of operation. In addition, the amount of energy generated by the photovoltaic carport was also measured. During the entire research period, the small electric vehicle was charged with State of Charge (SoC) 50% almost 900 times. Then, an analysis was performed to determine the adequacy of the carport peak power selection for the energy needs of the electric vehicle. Based on an analysis of the amount of electricity produced by the carport during the season of use of the electric vehicle, it may be concluded that the average production of electricity in the selected period is about 2 times higher than that required to fully charge the electric vehicle (100% of SoC). Therefore, when designing the carport, the power required to charge the electric vehicle was correctly forecast.
