Fossil fuels constitute the bulk of the world’s transportation system and are responsible for around 37% of the CO2 emissions from final consumer products. As a direct result, greener transportation solutions are increasingly gaining favor globally as a means to combat climate change. Despite the fact that these numbers, together with favorable financial subsidies and government incentives, indicate a bright future for EVs, there are associated negatives, particularly when it comes to the charging experience that EV owners have. Despite the encouraging figures, consumer reports on EV charging infrastructure still indicate unhappiness. Among the many issues that EV users have with public charging stations, including a lack of information, long wait times, frequent interruptions, and sluggish charging times, are the following: bad charging experiences [1]. Another gripe with electric vehicle owners is the abundance of charging applications and payment methods; this forces EV users to lug about several apps and add a plethora of payment methods just to find a charging station near them. One glaring example of these problems is the seeming mismatch between the quantity of charging facilities for electric vehicles and gas stations. Even while funding for gas stations has dropped in recent years, there are still more of them than charging stations for electric vehicles [2]. Because of this problem, charging stations tended to congregate at the day’s busiest times, which put a demand on the power infrastructure and caused it to overflow. Because of this problem, there is a pressing demand for automated billing solutions that prioritize satisfying customers. The Internet of Things (IoT) is one tool that may help bring about this change [3]. Everyday life around the world highlights the importance of autonomous charging technologies for better resource management, especially in developing nations where inequality in health, education, and poverty is a major policy concern. There is no better example of this than the dramatic shift from the “Big Data” era to the “Conventional Data” era. But how exactly does this supposedly intelligent technology affect the typical EV user’s charging experience? The Internet of Things (IoT) might mean various things to different individuals to signify various ideas for various uses. Internet of objects (IoT) depicts a more complex global infrastructure for the information society, allowing for enhanced services via the interconnection of (virtual and physical) objects based on current and future compatible ICTs. The Internet of Things (IoT) is a crucial piece of smart technology for managing and maintaining electric vehicle (EV) charging stations, which pose unique challenges due to their dispersed nature and intricate design. In addition, the Internet of Things may make it easier for customers to find charging stations, plan when their cars will charge, determine the best time to charge, and get details on what variables could influence the time it takes to charge [4]. By being able to research local charging stations online, EV owners may better manage their charging experiences, which in turn gives them a sense of agency over the products of contemporary technology. However, the infrastructure needed to enable EV charging stations based on the Internet of Things is not yet completely created, as was noted before. Data security and privacy issues are also parts of the EV charging mess. Two new answers to these problems are federated learning and blockchain technology. Up until now, the most recent research on electric vehicle charging via the internet of things has focused on the many effects of smart systems and intelligent technologies, butfails to conduct a thorough evaluation of EV uptake and use. Of course, in a transportation industry where heavy-emitting ICEs rule, there has to be a paradigm change towards cleaner, more economical transportation solutions. While there are several variables that affect the rate of EV adoption, one obvious barrier is the lack of familiarity with public charging facilities. To overcome this limitation, we need to implement strategies and procedures that will let electric vehicles (EVs) blend into transportation networks in a way that makes everyday tasks easier. This raises the following question: how important is the Internet of Things (IoT) in reducing the difficulties associated with public charging for electric vehicles (EVs) and the end-user and customer experience (CES) for CES? We surveyed the literature to learn about the interplay between the Internet of Things (IoT) and electric vehicle public charging, with a focus on the attendant effects on customer satisfaction, in order to answer this issue [5].
