Abstract

As the number of electric cars on the road grows, there is a growing need for a reliable charging infrastructure that can keep up with the rate at which people are switching to this way of getting around. At the same time, local power grids are getting overloaded and need help from renewable energy sources like wind and sun that are naturally abundant and cheap. As a result of this trend, the world has recently seen the introduction of charging stations that are powered by renewable energy sources. In this article, we\'ll talk about research that has to do with how different types of alternative energy sources can be charged. We offer in-depth research on this industry\'s most important factors, such as price, resources, potential, strategy, and control. Also, the problems that this type of electric charging station faces will be looked into, made clear, and workable solutions will be suggested after this study is done. This study has two goals: first, to give the reader an overview of how electric vehicles can be charged using renewable energy; and second, to lay the groundwork for more research on this very important topic

Introduction

The rise in the number of people who drive electric vehicles (EVs) has led to a rise in the demand for electricity in every part of the world. The global market for electric vehicles has grown a lot in recent years. In 2010, there were only a few hundred electric vehicles (EVs) on the road. By 2017, there were about three million EVs on the road, and by the beginning of 2019, that number is expected to reach about six million [1]. Electric cars are a great alternative to more traditional ways of getting around (CVs). Because they don't release carbon while running, EVs have the potential to make a big difference in the overall climate effect and in pollution levels. As fossil fuels are used up more and more, the demand for alternative fuels like biofuels is expected to go down. Electric motors can be 80–95% efficient, which makes them a better choice than CV motors, which can be less than 20% efficient. Electric vehicles are also an important part of today's transportation system because they use a lot of new manufacturing technologies (e.g., an electric motor, a battery, and a charging facility). Still, the number of electric cars on the road is not growing as quickly as was hoped. Electric cars have a short range, and it takes a long time to charge them. This is often seen as the biggest problem with getting them on the market. Electric cars cost more to buy up front, but they cost much less to run and maintain and use a lot less energy. As the demand for electric vehicles (EVs) and charging stations for EVs continued to rise quickly, many research centres and energy supply companies began to think seriously about how they could help ease the strain that the growing number of EV charging points was putting on local electricity networks. Renewable energy sources like wind and solar are some of the best ways for local electrical networks to make up for this shortage, and they could also help the infrastructure for charging electric vehicles. Around the turn of the century, when it became clear that EVs were growing quickly, research on renewable energybased charging infrastructure (RCI) began, with a focus on solar and wind charging infrastructure [7. It pictured a charging station that could meet the demand for electric vehicles (EVs) by using renewable energy sources and direct current (DC). This would make up for the problems with the charging infrastructure that was already in place. Traditional charging stations make the grid less reliable because they cause problems like harmonics, voltage fluctuations, and power outages [8. On the other hand, the RCI has a number of advantages, such as high efficiency, low system costs, and an easy setup. Also, it needs less power conversion than facilities that use alternating current (AC). [ The RCI has the potential to make a big difference in lowering carbon emissions and increasing the use of renewable energy sources in the energy sector. In addition to this, RCI could make it cheaper to charge electric vehicles [19]. But the RCI is hard to put into place because of things like the unpredictability of renewable

Conclusion

The way people get around in the future will be determined by how electric cars and renewable energy sources work together. The amount of carbon emissions and fossil fuels used will go down as the number of EVs and RCIs on the market goes up. But the natural changes they go through make it hard to set up infrastructures that run on renewable energy. When putting up wind turbines, you need to think carefully about both the location and the environment around it. It has been decided that cities are not good places for this because of the noise and the need for large spaces. Solar systems only make power during the day, so they can\'t meet the large daily demand for electricity. Wind and solar power are being looked at as possible ways to power charging stations for electric cars. But if it is used with electric vehicles, V2G charging stations, and energy storage systems, it could be used as part of a charging strategy for a micro grid. The issue of charging schedules is now the subject of a lot of research, which was brought to the attention of optimal planners. During the planning phase, some of them think about how V2G and renewable sources could work together. RCI planning is hard because renewable sources are available, traffic needs are hard to predict, location design is complicated, and there are other things that affect hourly power management, like renewable sources, grid peak hours, and V2G. All of these things make it hard to plan because they all affect each other. Research shows that not nearly enough studies have been done on the infrastructure for charging renewable energy sources to use real data to improve control strategies, scaling, and
