“…Due to automation, wireless charging of EVs could offer and produce bidirectional power flow between EVs and the grid. The comparison of interactivity between wired and wireless connections was briefed in [217,218]. According to the studies mentioned above, wireless connectivity or charging could achieve up to 65% connectivity, whereas conventional connectivity only achieved rates of 10% [219].…”

Electric vehicles could be a significant aid in lowering greenhouse gas emissions. Even though extensive study has been done on the features and traits of electric vehicles and the nature of their charging infrastructure, network modeling for electric vehicle manufacturing has been limited and unchanging. The necessity of wireless electric vehicle charging, based on magnetic resonance coupling, drove the primary aims for this review work. Herein, we examined the basic theoretical framework for wireless power transmission systems for EV charging and performed a software-in-the-loop analysis, in addition to carrying out a performance analysis of an EV charging system based on magnetic resonance. This study also covered power pad designs and created workable remedies for the following issues: (i) how power pad positioning affected the function of wireless charging systems and (ii) how to develop strategies to keep power efficiency at its highest level. Moreover, safety features of wireless charging systems, owing to interruption from foreign objects and/or living objects, were analyzed, and solutions were proposed to ensure such systems would operate as safely and optimally as possible.

“…This is described in the analyzes by varying the investment cost in the various calculations and by varying the number of fuel-powered vehicles that switch to electric operation. Electric roads are a relatively new field, and articles and reports in the literature have been used to find information [8], [11]- [14]. Relevant literature was used to find information about EBs and especially the characteristics of batteries.…”

This article is designed to demonstrate why we need to believe electric roads are an affordable way to electrify all forms of road transport; not only cars but also buses and trucks also. Electric roads mean a way to power electric vehicles without relying solely on the battery. The idea is that when an electric vehicle reaches an electric road it stops using power from the battery and instead uses power directly from the road itself. It is similar to the way that we power trams and electric trains nowadays. The big challenge for electric vehicles is still a perceived and compromising quality of life when having an electric vehicle due to the limited range compared to petrol and diesel cars today. This paper introduces a new technology that is currently experiencing rapid development which can not only overcome range anxiety but actually make electric vehicles better in terms of range than petrol and diesel cars today. Furthermore, not only would have helped arrange it will also help us for the first time to cost-effectively electrify heavy-duty transport like trucks and buses which would be a huge breakthrough for sustainability. Because it is really important to start supplying electricity to heavy-duty vehicles. The case study provides a very hypothetical example of a trip with and without an electric road, covering a total of 26011km of highways and main roads in the country. The results have indicated that building electric roads is cheaper than a lot of other alternatives. The main reason is the amount of money currently spent on transport infrastructure. This paper can help transport operators and policymakers develop strategies to accelerate the adoption of electric vehicles by appropriately implementing electric road infrastructure.

The surge in popularity of electric vehicles (EVs) can be attributed to significant advancements in performance and driving range. Traditional EVs rely on cable charging, but major manufacturers like Tesla, BMW, and Nissan are spearheading the development of wireless charging technology, eliminating the need for cumbersome wires. This wireless, inductive charging not only enhances safety by eliminating sparks but also opens up possibilities for dynamic charging, allowing EVs to charge while in motion. Once fully implemented, this innovation could reduce the reliance on large batteries and alleviate range anxiety associated with EVs. Countries such as Korea, Germany, and the UK are actively driving the adoption of wireless charging. Extensive research literature delves into the technical aspects of wireless charging, including communication protocols, coil design, and compensation methods. Innovative approaches such as utilizing superconducting materials in coil designs are explored for their potential to enhance charging efficiency. Safety concerns related to wireless charging are addressed along with an overview of relevant standards. Additionally, the study provides an economic analysis of the costs associated with various wireless charging setups. Overall, this research contributes to the understanding of wireless EV charging and highlights its transformative potential for the industry.
