“…Such a scenario shall not be regarded as a risky one, since Frost&Sullivan have predicted an annual growth for inductive charging market of 126.6% from 2012 to 2020 3 . The discount rate is set at 7.10%, which is the cost of equity that has been calculated.…”

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.

a b s t r a c tThe deficiency in the availability of petroleum products has given rise to the incorporation of electric vehicles (EVs) globally as a substitute for the conventional transportation system. Significant research has been pursued over last two decades in the development of efficient EV charging methods. A preliminary review of few methods developed for wireless charging revealed that ICPT is a promising and convenient method for the wireless charging of EVs. This paper includes the equivalent circuit analysis and characteristics of the ICPT system and focuses on the research progress in respect of the designs for the charging coil, leakage inductance compensation topologies, power level enhancement and misalignment toleration. The improvement in these factors has been essential for the implementation of EV charging. A brief discussion over design process and control of ICPT system has been added. Conclusions have been made on the basis of the information extracted from the literature and some future recommendations are provided.

“…To overcome the shortcomings of the circular pad structure, a new battery charging magnetic structure using bars has been proposed [17][18][19]. This bar pad structure creates essentially a horizontal flux profile compared with the vertical fields of the circular pads as shown in the comparisons of Fig.…”

Plug-in EVs are being heralded as a step towards acceptance of pure EV's. However concerns remain regarding uptake by consumers, in terms of range anxiety and economic operation. These concerns are mitigated if energy can be transferred to the vehicle while it is moving, but there are implications in terms of the highway infrastructure required without restricting a vehicle's freedom to move while providing power over air-gaps in excess of 200mm. Such flexibility brings with it problems that are not normally inherent in stationary systems where electronic alignment may be employed to control magnetic coupling.The system must cope with variances as seen by both the power supply and the EV, while ensuring that the power receiver is compatible with both stationary and roadway systems. This paper discusses recent developments in wireless charging infrastructure for EV's and describes systems that may be suitable in future. As vehicles operate on the Grid they will constitute a substantial load that must be managed. A solution is presented here at little infrastructural cost such that the Grid, 'on load' has better power quality than 'off-load'.
