Solar Battery Charging Station for Electric Vehicles: Part I- Screening, Modeling, and Feasibility Analysis

Abstract

This is the first of a set of papers dealing with the screening, modeling, and feasibility analysis of solar battery charging stations in Bangladesh. Increased use of renewable energy will reduce the price and demand for fossil fuels. Photovoltaic solar energy is mainly used for various purposes such as heating, cooking, and power generation. Recent discoveries have helped in the development of solar-powered vehicles. To provide adequate charging rates, the increasing use of electric cars and hybrid electric vehicles necessitates the development of efficient charging stations. This will overload traditional networks, increasing charging costs. As a result, the use of onsite renewable sources such as photovoltaic electricity in addition to conventional grids can improve charging station performance. On the other hand, PV is known for its discontinuous nature, which is highly dependent on geographical and meteorological conditions. To account for PV’s intermittent nature, the battery storage system is integrated with PV in a grid-connected system to assure the PV-based hybrid charging station’s reliable functioning. In general, hybrid-powered charging stations should be cost-effective, have higher efficiency, and have better reliability to meet the fluctuating demand for electric vehicle loads under various circumstances. This paper will demonstrate the system design and performance analysis of solar electric vehicle systems, as well as propose a design of solar charging stations for EVs to address the ever-increasing energy demand for electric vehicles in the near future and to reduce the problems encountered in the process of utilizing renewable energy.
