“…These pad-based transmitters inevitably involve a large amount of primary pads, power inverters or power switches and sensors, thus suffering from huge investment cost and high installation complexity. Although the reflexive segmentation layout can partially solve this problem by using only one power inverter [35], it still needs a large amount of primary pads. In contrast, the rail design involves only a primary rail or actually a long primary coil and a power inverter to feed multiple BEVs as shown in Fig.…”

Abstract-There is no doubt that electrified vehicles are superseding internal combustion engine vehicles for road transportation. Among them, electric vehicles (EVs) have been identified as the greenest road transportation while hybrid EVs have been tagged as the super ultra-low emission vehicles. In this paper, the definition, classification, merits and demerits of electric and hybrid vehicles are first introduced. Then, after revealing their multidisciplinary technologies and development trends, the state-of-the-art electromagnetics research in electric and hybrid vehicles are discussed, with emphasis on electric motors for electric propulsion, electric machine systems for hybrid propulsion, wireless power transfer technologies for park-and-charge a well as move-and-charge, electromagnetic interference and compatibility issues in EVs, electromechanical flywheels for energy storage and magnetic sensors for EV operation. Meanwhile, the development trend of these research areas is revealed.

“…In [15,16], multiple short transmitters are arranged on the lane of the vehicle, and the system is flexible for design and installation. However, it requires a great quantity of compensation components, and the output power reduces to almost zero between two transmitters requires a great quantity of compensation components, and the output power reduces to almost zero between two transmitters due to the existence of a dead point [17]. A novel T-type compensation network is proposed in [18], which keeps a stable transmission power.…”

A dynamic wireless power transfer (WPT) system is an effective method, which can reduce charging time and extend the driving range of the electric vehicles. In the dynamic WPT systems, the output voltage may fluctuate when the receiver moves along the transmitter coils. This paper proposes a three-phase dynamic WPT charging system with overlapped three-phase transmitter coils. The overlap length is optimized to depress the fluctuation of the output voltage. These coils are powered by a three-phase inverter to generate an even magnetic field, and a unipolar coil is employed as a receiver to simplify the coil structure of the secondary side. Based on the proposed three-phase coil structure, the output voltage characteristics of the system are analyzed in detail. A 500 W dynamic charging prototype is established to validate the proposed dynamic charging system. Experimental results show that the output voltage fluctuation is within ±3.05%. The maximum system efficiency reaches 89.94%.

“…The operation of each pad may be managed by separate power electronic interfaces increasing, thus, considerably the cost of such solution. In this respect, new control techniques have been proposed in the literature enabling the management of two or more pads by the same power electronic interface [13]- [14].…”

Fast inductive charging, can dramatically change the "usability" and attractiveness of electric vehicles to consumers by improving both the charging duration and the convenience offered. Even though wireless charging technology is rather premature, there are already some commercially available solutions enabling slow charging (i.e. 3.3kW) which are compatible with specific car models (e.g. Nissan, Siemens, Bosch/Evatran [1] etc).The operational principle of the Inductive Power Transfer Module (IPTM) resembles to the one of transformers; transferring energy from a primary to a secondary coil (usually referred to as "pick-up coil") which are not physically connected as it is presented in [2] ABSTRACTThe aim of this paper is to introduce a complete fast dynamic inductive charging infrastructure from the back-office system (EV management system) up to the Electric Vehicle (EV) (inductive power transfer module, positioning mechanism, electric vehicle modifications) and the EV user (User interface). Moreover, in order to assess the impact of the additional demand of inductive charging on the grid operation, an estimation of the 24-hour power profile of dynamic inductive charging is presented considering, apart from the road traffic, the probability of the need for fast charging, as well as the specifications of the proposed solution. In addition, an energy management system is presented enabling the management of the operation of the inductive charging infrastructure, the interaction with the EV users and the provision of demand response services to different stakeholders. The proposed dynamic inductive charging approach has been demonstrated within a real urban environment in order to provide useful insights regarding the experience gained from a real-field trial. The relevant practical conclusions are also discussed in this paper. Finally, a cost/benefit analysis, according to the Discounted Cash Flow (DCF) principles, is performed in order to assess the economic viability of the proposed solution.
