Electric vehicles (EVs) have recently been significantly developed in terms of both performance and 10 drive range. There already are various models commercially available, and the number of EVs on road 11 increases rapidly. Although most existing EVs are charged by electric cables, companies like Tesla, 12 BMW and Nissan have started to develop wireless charged EVs that don't require bulky cables. 13 Rather than physical cable connection, the wireless (inductive) link effectively avoids sparking over 14 plugging/unplugging. Furthermore, wireless charging opens new possibilities for dynamic chargingcharging while driving. Once realised, EVs will no longer be limited by their electric drive range and the requirement for battery capacity will be greatly reduced. This has been prioritised and promoted worldwide, particularly in UK, Germany and Korea. This paper presents a thorough literature review on the wireless charging technology for EVs. The key technical components of wireless charging are summarised and compared, such as compensation topologies, coil design and communication. To enhance the charging power, an innovative approach towards the use of superconducting material in coil designs is investigated and their potential impact on wireless charging is discussed. In addition, health and safety concerns about wireless charging are addressed, as well as their relevant standards. Economically, the costs of a wide range of wireless charging systems has also been summarised and compared.

“…The inductive WPT system has its own drawbacks and the use of this technology is problematic in many fields. The inductive WPT system has the EMI issue, electromagnetic radiation is proven to have adverse effects on the environment and health [3] of the people exposed to the radiation, therefore shielding is required. The shielding and use of magnetics makes the cost of such system extremely high [4].…”

“…Nowadays, WPT systems have become more and more widely used and investigated, the review of scientific achievements in the field of WPT is given in [1][2][3] and in other publications. Main benefit from WPT implementation is that no wire is needed anymore to transfer energy between the power source and load.…”

The paper discusses the capacitive wireless power transfer (WPT) system for small portable device charging. The capacitive WPT can replace a conventional inductive coupling WPT, because it has no electromagnetic interference, but the capacitive WPT has limitation due to too small coupling capacitance. Therefore, to utilize the capacitive WPT system the switching frequency should be as high as possible: therefore, challenges associated with the design of the power converter working in MHz range will be discussed in details. A calculation of passive components, matching the network and capacitor plate design methodology is given in the paper. The design of the prototype of the capacitive WPT will be described in the paper. This paper proposes to use two copper plates to transfer power, the plates are adopted to generate electric fields and transfer power from the primary side to the secondary side. The equations for calculation of capacitance of the plates are given in the paper. An important task is to calculate the resonant network that generates high voltage in the circuit for high power transfer. The high switching of inverter transistors requires high performance transistors with optimized driver circuit. The design of the inverter and driver circuit is discussed and experimental results are shown.

“…However, compared with fuel vehicles, EVs are still faced with problems such as large size and low energy density of energy storage equipment, frequent charging and insufficient driving range [1]. The static wireless charging technology for EVs is helpful to solve the issues of wired charging, such as frequent plug-in, contact wear and tear, electric shock risk and lack of user experience [2].…”

In order to promote the driving range of the electric vehicles (EVs), decrease the demand for large capacity battery and create more charging opportunities for the EVs, the static-dynamic hybrid wireless charging system is presented to utilize waiting time of traffic lights at intersections to replenish electricity in this paper. Firstly, the topology and principle of the proposed static-dynamic hybrid wireless charging system with short-segmented coils at traffic lights are introduced. Secondly, the general circuit model of the static-dynamic hybrid wireless charging system with multi-coupling between the primary and secondary sides is developed. The design method of the compensation circuit in primary side based on the number and the positions of the energized primary coils is investigated. After analyzing the characteristics of the system varying with the position of the single load, the control conceptions of the energizing mode alternating in primary side and the combination of the primary compensation capacitors are put forward. Then the power stabilization control strategy of the static-dynamic hybrid wireless charging system with multi short-segmented coils and multi loads is proposed. Finally, the theoretical analyses are verified with the experiments.
