Design of a photovoltaic based Electric Vehicle (EV) charging station

Abstract

Day by day electric vehicles like auto-rickshaw, Easy bikes are increasing in Bangladesh. In Bangladesh, easy bikes are charged using electricity from the national grid. This increasing number of electric vehicles creates a lot of pressure on the country’s grid. Bangladesh is already lagging behind in the production of electricity. To reduce the pressure of the national grid and utilize renewable energy this study deals with the design of a photovoltaic (PV) based Electric Vehicle charging station. Easy bike charging by renewable energy is like solar offers a good solution from an economic and environmental point of view. The 3D model of the desired charging station has been included in this paper. This station is made for 15 easy bikes charging capacity which requires 21.6 kWh of energy daily on average. This design includes site selection, irradiation calculation, load estimation based on the vehicle survey, PV panel choosing, possible system loss, energy assessment, battery storage, cloud impact, grid dependency. In this study, a photovoltaic based easy bike charging station has been designed considering environmental impact. For this design total life cycle has been calculated. Additionally, carbon emission analysis has been done. The result shows that 16162.96 kg/kWh CO2 per year can be minimized by the proposed design compared with fuel-based cars.
