Design and Analysis of a Solar-Powered Electric Vehicle Charging Station for Indian Cities

Abstract

Due to depleting fossil fuel reserves coupled with a climate crisis, sustainability is gaining ground, and electric vehicles (EVs) are emerging to be the new face of this field. However, the idea of EVs will be genuinely sustainable only if they are charged using renewable energy. This paper presents results from the design of a solar-powered EV charging station for an Indian context. PVsyst 7.2 software has been used for the system design. The analysis, based on the number of cars charged annually, the monthly variation in energy generation, the investment cost, and the decrease in carbon dioxide (CO2) emissions using different module technologies for six Indian cities, has been deliberated. The results indicate that an off-grid 8.1 kWp system with two days of battery autonomy has the fewest unused energy losses, with a good performance ratio (PR). It can completely charge around 414 vehicles of 30 kWh battery capacity annually. This would help to reduce annual CO2 emissions by approximately 7950 kg. For cities near the equator, maximum energy is produced during March or January, and for cities near the Tropic of Cancer, energy production maximizes during May–June. The overall system has better energy generation and economy when monocrystalline modules are used.

Integration Challenges and Solutions for Solar-Powered Electric Vehicle Charging Infrastructure: From Panel to Battery

“…This integration poses unique challenges due to the bidirectional nature of power flows and the variable output of solar generation. Infrastructure and grid integration must be approached with an emphasis on compatibility, reliability, and scalability to ensure a resilient power network [33]. Compatibility is central to the integration process, involving the synchronization of the EV charging stations' power output with the grid's voltage and frequency levels.…”

Revolutionizing mobility: a comprehensive review of electric vehicles charging stations in India

“…Electricity acts as the fuel for EVs and alternative renewable sources of electricity must be used for further facilitation of EVSE installation and EV use. The use of renewable sources of power generation such as solar PV systems and pumps-used-as-turbines (PATs) to charge EV batteries is studied in Balacco et al (2021) and Singh et al (2022). Wireless charging of EVs is an emerging trend that researchers have put forth where charging is done by inductive or capacitive coupling, which is yet to be started in India.…”

Optimisation of a standalone photovoltaic electric vehicle charging station using the loss of power supply probability

“…Caines et al evaluated the impact of BESS on the independence of a grid-connected PV charging station, found that the effectiveness of BESS in a grid-connected PV charging station is strongly influenced by the pattern of charging demand profile [ 27 ]. Singh et al assessed the feasibility of a standalone PV charging station in India, resulting that although the land utilisation of a standalone charging station is 16 times more than a grid-connected charging station, it is more advantageous in remote areas and areas where the grid is not well developed [ 28 ]. Akhtar team optimised the capacity of BESS in terms of reducing peak loads, minimising BESS costs and enhancing EVs' resilience [ 29 ].…”
