“…These configurations include class EF [116], current source push-pull [117], [118], and voltage source 1-ph, 3-ph, or multi-phase [69], [119], [120], [121]. In [122], the authors propose the use of an H-bridge converter on the ground side. On the vehicle side, two Hbridge converters are employed, with one supplying active power to the battery and the other regulating the charging current.…”

The wireless power transfer (WPT) system holds potential as a viable solution for charging electric vehicles (EVs) owing to its benefits including safety, automated operation, efficiency, and simplicity. Among the WPT technologies, inductive power transfer (IPT) stands out as particularly well-suited for charging EV batteries. This is primarily due to its capability to transmit high power across considerable air gap distances, accommodating the ground clearance requirements of most EVs, operating automatically without driver involvement, ensuring safety and convenience even in challenging conditions such as snow, rain, and dust, and offering maintenance-free operation by eliminating the need for plug-in connections. This manuscript provides a comprehensive exploration and analysis of the progress made in IPT technology. The manuscript introduces the operational principle of the IPT system and highlights the benefits of its components. Additionally, it discusses the transmitter and receiver architectures, outlines the characteristics of various charging pads, in case of both stationary and in-motion charging scenarios. Furthermore, it delves into different compensation circuit topologies and various WPT designs based on compensating structures associated with the IPT system. It also categorizes the converter topologies utilized in the system and presents the operating technique for each one. In addition, the ongoing research and development (R&D) endeavors pertaining to each technology are discussed, addressing challenges, existing gaps, and offering recommendations for further advancements in both stationary and in-motion charging applications.

“…Additionally, a mixed-integer linear programming model is developed for planning PEV fast-charging stations, by taking high voltage distribution networks and transportation networks as well as electrical network constraints into account. In [229], the efficiency of wireless charging is increased from 84.9% to 95.7% by augmenting an active power source into the receiver. The main drawback of this method is its inferior efficiency compared to conductive methods.…”

Impact of Transportation Electrification on the Electricity Grid—A Review

et al. 2022

Transportation electrification is a pivotal factor in accelerating the transition to sustainable energy. Electric vehicles (EVs) can operate either as loads or distributed power resources in vehicle-to-grid (V2G) or vehicle-to-vehicle (V2V) linkage. This paper reviews the status quo and the implications of transportation electrification in regard to environmental benefits, consumer side impacts, battery technologies, sustainability of batteries, technology trends, utility side impacts, self-driving technologies, and socio-economic benefits. These are crucial subject matters that have not received appropriate research focus in the relevant literature and this review paper aims to explore them. Our findings suggest that transitioning toward cleaner sources of electricity generation should be considered along with transportation electrification. In addition, the lower cost of EV ownership is correlated with higher EV adoption and increased social justice. It is also found that EVs suffer from a higher mile-per-hour charging rate than conventional vehicles, which is an open technological challenge. Literature indicates that electric vehicle penetration will not affect the power grid in short term but charging management is required for higher vehicle penetration in the long-term scenario. The bi-directional power flow in a V2G linkage enhances the efficiency, security, reliability, scalability, and sustainability of the electricity grid. Vehicle-to-Vehicle (V2V) charging/discharging has also been found to be effective to offload the distribution system in presence of high EV loads.

“…Between various eco-friendly resources, electric vehicles with wireless power transmission attract attention [10]. Therefore, there are researches to improve the power receiver technology [11], plans to set wireless charging infrastructure [12], or locate wireless charging lanes for vehicles that can maximize recharged electricity while maintaining small road congestion [13]. However, in order to apply wireless power transmission technology to transportation, it is necessary to transmit a large amount of electric power with high efficiency through a relatively large air-gap.…”

As an alternative to the environmental pollution problem of transportation means, the application of electric tram is considered in urban areas. However, due to the aesthetic problems occurs by the electric supply line for an electric tram, the wireless charging electric tram may be regarded as an alternative. It can be supplied electricity wirelessly from the wireless charging infrastructure installed on the railways even while moving. For a successful application, it is important to install and operate the overall systems with minimum investment cost. In this study, a mathematical model-based optimization technique, one of the methods of operations research, is adopted to derive the decision-making elements such as capacity and management of battery and allocation of the wireless charging infrastructure. Numerical example shows the optimal capacity and management of battery for a wireless charging electric tram and the ideal installation locations of the wireless charging infrastructures.
