Abstract
The rapid rise of electric vehicles (EVs) in India wants more energy to power these vehicles. In addition, the transport sector emits greenhouse gases (GHGs) and especially carbon dioxide (CO2). Due to the additional electricity required to charge these electric vehicles, the national electricity grid has to deliver more than 1500 megawatts per day. The proposed system offers an electric vehicles charging station (EVCS) using both solar energy and biogas fuel in order to decrease the dependence on the national power grid. The proposed system is a combination of a PV solar module (15 kW) and biogas generators (10 kW) and a converter (15 kW), 27 lead-acid batteries (100 Ah each), and charging equipment of EVs. The proposed system consists of the economic and environmental, technical analysis of using the renewable energy optimization by HOMER-Pro software tool. The article estimates the levelized cost of energy (LCE) of the system at US$ 0.1902/kWh, the system net present cost (NPC) at US$ 68,202, and the system operating and maintenance cost (O&M) at US$ 2,820. Also, the proposed system has potential benefit to reduce CO2 emissions by nearly 44.16% per year as compared to the conventional EVCS. The proposed system also saves nearly US$ 13-17 per month to charge an electric vehicle.
