“…Unlike far field, near field power transfer is non-radiative so the transferred energy remains within close proximity to the transmitter reducing issues concerning human exposure to the energy and magnetic fields [36]. In order to increase the power transfer, efficiency and range, coupled magnetic resonance is utilised in EV applications [37]. Such WPT charging technology use two resonant circuits that resonate the coils at the same frequency in order to maximise energy transfer through a Resonant Magnetic Coupling (RMC) [38].…”

Wireless Power Transfer (WPT) offers a viable means of charging Electric Vehicles (EV)'s whilst in a dynamic state (DWPT), mitigating issues concerning vehicle range, the size of on-board energy storage and the network distribution of static based charging systems. Such Charge While Driving (CWD) technology has the capability to accelerate EV market penetration through increasing user convenience, reducing EV costs and increasing driving range indefinitely, dependent upon sufficient charging infrastructure. This paper reviews current traction battery technologies, conductive and inductive charging processes, influential parameters specific to the dynamic charging state as well as highlighting notable work undertaken within the field of WPT charging systems. DWPT system requirements, specific to the driver, vehicle and infrastructure interaction environment are summarised and international standards highlighted in order to acknowledge the work that must be done within this area. It is important to recognise that the gap is not currently technological; instead, it is an implementation issue. Without the necessary standardisation, system architectures cannot be developed and implemented without fear of interoperability issues between countries or indeed systems. For successful deployment, the technologies impact should be maximised with the minimum quantity of infrastructure and technology use, deployment scenarios and locations are discussed that have the potential to bring this to fruition. IntroductionThe electrification of road transport provides a viable means of reducing fossil fuel consumption and environmental pollution, hence the recent advancements in Electric Vehicle (EV) design and performance [1]. However, the high costs and poor specific energy densities of batteries compared to fossil fuels results in a less than ideal scenario [2]. Due to their relatively shorter range, EV's require more frequent charging (than refuelling of Internal Combustion Engine (ICE) vehicles) to maintain a desirable range and with long charge times (compared with conventional refuelling times) or potential battery degradation that occurs during rapid charging; battery charging technology has restricted EV development. With no significant advancements in battery technology that would bring EV range in line with comparable ICE vehicles forecasted within the foreseeable future [3] this has resulted in substantial research into alternative charging methods. Whilst conventional plug in charging is the most common form, there are still conductive energy losses within the system resulting in an overall efficiency of around 86% [4] and potentially lower for rapid chargers. In addition, the high power transfer, human handling and the ability for the user to forget to plug in/out result in a pragmatic scenario.Wireless Power Transfer (WPT) technology is capable of mitigating the issues of plug in charging; the EV is parked over a coil that inductively transfers electrical energy to a receiver coil positioned on the vehicle. ...

“…The compensation networks can be classified into four types: the series-series (SS), parallel-parallel (PP), series-parallel (SP), and parallel-series (PS) types. Source compensation is used to reduce the reactive power on the transmitter side [11,14], and receiver compensation is used to maximize the power transfer and efficiency. The features of the compensation networks are listed in Table 1 [15,16].…”

This paper presents a novel inductive link for wireless power transfer (WPT) system of electric vehicles (EVs). The WPT technology uses an alternating magnetic field to transfer electric power through space. The use of the WPT technology for charging electric vehicle provides an excellent alternative to the existing plug-in charging technology. It has been reported that the inductive link using planar coils such as the circular and rectangular coil are capable of transferring a high power with high efficiency. However, they have a poor tolerance for lateral misalignment, thus their power transfer efficiency decreases significantly with the misalignment. Due to the poor misalignment performance of the planar coil topology, extensive studies have been carried out on the flux pipe topology due to their excellent misalignment tolerance. To address this, in this paper, a novel inductive link using double helix flux pipe topology is proposed. The performances of the inductive link using the proposed double helix flux pipe are analyzed and compared with inductive links using conventional flux pipe. The proposed model has excellent characteristics in terms of the power transfer efficiency and tolerance against misalignments. The proposed model is capable of transferring over 1.6 kW of power with a coil-to-coil efficiency of over 98.5% at a load resistance of 20 Ω.

“…In WPT systems, the leakage inductance in the primary and secondary coils is high due to loose coupling. Therefore, to reduce the apparent power rating, a compensator network is required [71–109]. Though the authors of [69–71] present an extensive review about the various known technologies in the contactless energy transfer system, it failed to reflect the potential of various applications like renewable energy integration and vehicle‐to‐grid integration, which is having a high impact on energy conservation and clean transportation.…”

The quest for energy conservation is a thought-provoking conundrum to researchers. Time to time they contributed towards this pursuit. In the 19th century, it was a fascinating idea about electric vehicles (EVs). As most of the developing countries depend on conventional energy sources, integration of EVs with renewable energy sources justified the cause. The parking slots became transformed into unlimited sources of clean energy. For the comfort of charging and better energy management, wireless power transfer technology was introduced to the charging station. As a fulfilment of the technology, the vehicle-to-grid (V2G) integration was implemented. It helped the bi-directional power flow between the vehicle and the grid with renewable energy. This study presents an extensive review of the renewable energy powered wireless charging and V2G integration of EVs. Various topologies are discussed with mathematical explanations and block diagrams. Concepts are validated with PSIM simulations.
