| Abstract | This paper explores the development of photovoltaic (PV) and battery grid-connected systems to enhance plug-in electric vehicle (EV) charging in residential areas. The study employs a rooftop PV grid-connected system designed for a residential area with typical monthly electricity consumption, aiming to analyze the impact of power usage on household EV charging. The proposed system evaluates and compares four EV brands with power ratings of 105, 110, 120, and 110 kW. Findings indicate that the average daily power demand is 8 kWh, covering both quick and conventional charging modes. Among the four brands, the second brand exhibited the highest energy consumption for fast charging, totaling 3,096 kWh annually, while the fourth brand consumed the most power for normal charging, reaching 2,859 kWh per year. The annual electricity procurement cost from the grid was calculated at 76.80 kWh. PVsyst analysis revealed a system performance ratio of 76.6%, capable of generating 21,826 kWh/year, with 5,390 kWh/year consumed by AC loads. Financial assessments identified the optimal choice for the 120-kW fast charger from the fourth brand. The study confirms that integrating PV with a battery energy storage system offers an efficient solution for improving plug-in EV charging in residential microgrids. |
