Paper Proposal Text :
The global automobile industry encompasses both conventional as well as non- conventional powered vehicles. The market share of electric vehicles is slowly increasing with companies like Tesla releasing cars that reach speeds and driving range comparable to gasoline powered vehicles. Though electric vehicles are touted as the next replacement for gasoline vehicles, widespread acceptance of electric vehicles is still lacking as many concerns still persist.
Even though the market share of electric vehicles has risen steadily over the years, its success in terms of mass adaptation highly depends on the availability of charging infrastructure and eliminating ‘range anxiety’. This paper focuses on eliminating these bottlenecks by introducing a fast charging wireless system, which will provide a convenient and a safe way of charging electric vehicles (EV).
As of today, there are three major charging standards for conventional electric wired chargers. These include the CHADEMO standard used by Japanese manufacturers, the SAE standard used by American and European manufacturers and a completely different charging standard adopted by Tesla cars [1]. So this product provides an immense benefit by trying to remove these barriers between different vehicle manufacturers by providing a universal charging standard that works with every single electric vehicle present in today’s market.
There has been much criticism about the use of fossil fuels such as natural gas for providing electricity for charging vehicles. This paper seeks to dispel critics’ views by attempting to implement this charging infrastructure powered by distributed solar panels, a move that works well with a ‘Smart City’ infrastructure plan. Additionally, a software stack in the form of a mobile platform is built on the charging infrastructure that we provide. In the past, a number of researchers have proposed wireless charging solutions [2]. A prototype system demonstrating the wireless charging principle is fabricated for a 150W load and the results obtained after simulating the individual components making up the WPT system have been provided. The concept of a solar-powered WPT system, capable of providing power to any EV making use of the WPT principle is introduced. Lastly, a theoretical design for a 3.3 kW WPT system is provided and a receiver system is approximated for Renault Twizy, whose battery capacity is rated at 6 kWh.
Apart from presenting a prototype, this paper also covers a unique implementation model that can exponentially improve the current charging infrastructure in smart cities. Anticipating a surge in demand for EVs, this paper proposes a ‘shared economy’ business model. In such a model, customers who purchase a wireless charger and installs it at a parking spot or in their personal driveway can list their chargers on a charging network. This can enable other Electric Vehicle owners to use these charging stations when they find themselves short of charge, thereby eliminating ‘range anxiety’. As a result, the charging station owners can earn money whenever they are not using them. Keeping in mind the projection of future demand of EVs, an economic analysis of owning and operating such a system is carried out. Preliminary analysis shows that such a model is capable of being lucrative for all stakeholders involved and will potentially save money for any government, who will not have to bear a majority of the charging infrastructure costs.
