In a context of growing electrification of road transport, Wireless Power Transfer (WPT) appears as an appealing alternative technology as it enables Electric Vehicles (EVs) to charge while driving and without any mechanical contact (with overhead cables or rails in the ground). Although the WPT technology background dates from the end of 20th century, recent advances in semiconductor technologies have enabled the first real demonstrations. Within the FABRIC European project, the French research Institute VEDECOM and its partners implemented a whole prototype wireless power transfer charging infrastructure. The first demonstrations of Inductive WPT in different real driving conditions (up to 20 kW, from 0 to 100 km/h, with one or two serial vehicles) were provided. This paper describes the prototype equipment and its instrumentation and provides the system characterization results. The future of the Inductive WPT technology is further discussed considering its different technical and economic challenges. In parallel, how this technology could be part of future generation road infrastructures is discussed. Future research and demonstration steps are presented in the conclusion.

India has taken major step in adopting the electric vehicle by means of FAME Scheme (Fast Adoption and Manufacturing of Electric Vehicles), a government initiative. ARAI (Automotive Research Authority of India) and DHI (Department of Heavy Industry) have published standardization protocol for both EV charging infrastructure. Many of those standards are derived from the SAE (Society of Automotive Engineers) Internationals and IEC (International Electrotechnical Commission). USA, Europe and China are also following the same standards to build the EV (Electric Vehicle) infrastructure. This paper provides the Indian standards to build EV charging infrastructure and comparing it with other countries. Glimpses on energy demand for electric vehicles in Indian market. It also provides the demanding wireless power transfer technology in EV’s. Status of Standards provided by the industry on wireless power transfer. Factors that are necessary to be considered before drafting the standards for WPT.

The Road

Electric Vehicles (EVs) are considered to be one of the most sustainable forms of transportation. Unlike hybrid vehicles or gas-powered cars, EVs run solely on electric power. However, despite their many benefits, EVs are facing major challenges in the market today. The major challenge being its exorbitant costs as compare to fuel-based cars. And, range anxiety also proves to be a hurdle for EVs [6]. Thus, to answer all the aforementioned challenges, we proposed Electro-Magnetic Induction-based Roads (EMIR), a dynamic wireless recharging system. EVs would be able to slip into a special EMIR green lane, recharge their batteries a bit, and slip out. This technology will thus reduce the size of the EV battery, which is the most expensive part of the EV, by increasing its effective mileage and the life of the battery. This paper elaborates on the method of performing dynamic wireless power transfer through resonance based electromagnetic induction. A 163 cm long and a 30 cm wide transmitter coil was designed to transfer electrical energy to an oval-shaped receiver coil with 40 cm as its major axis and 30 cm as its minor axis. The EV battery is dynamically recharged by a charging infrastructure between the road and the vehicle while it is in motion with a high efficiency. The transmitter coils are essentially supposed to be embedded in the road but are placed over the road for visual purposes. The receiver coil is placed under the EV. When the EV goes over the electric road, it gets dynamically recharged. A prototypic EMIR was successfully designed to demonstrate the Dynamic Wireless Power Transfer (DWPT) for EVs.
