“…Figure 13 presents the efficiency indicator (percentage of maximum efficiency recorder during the 54-test series) versus the misalignment data. As reported in the preliminary results reported in [42] (p. 576) on the tested prototype, the total efficiency measured grid to battery reached around 70%. The value appears to be relatively low, which is explained firstly by the strong innovative concept of the system using only one AC converter for several distributed coil emitters.…”

“…The goal of the FABRIC European project, which started in 2014 and finished mid-2018 [41], was to assess the feasibility of different on-road charging technologies for the range extension on EVs and pave the way for future potential deployments. In order to bridge the gap between laboratory and operational environment, the specifications for the IPT demonstrations operated by the FABRIC partner VEDECOM in collaboration with Qualcomm CDMA Technologies GmbH (Qualcomm) and Renault were set as follows [42] (p. 571):…”

In a context of growing electrification of road transport, Wireless Power Transfer (WPT) appears as an appealing alternative technology as it enables Electric Vehicles (EVs) to charge while driving and without any mechanical contact (with overhead cables or rails in the ground). Although the WPT technology background dates from the end of 20th century, recent advances in semiconductor technologies have enabled the first real demonstrations. Within the FABRIC European project, the French research Institute VEDECOM and its partners implemented a whole prototype wireless power transfer charging infrastructure. The first demonstrations of Inductive WPT in different real driving conditions (up to 20 kW, from 0 to 100 km/h, with one or two serial vehicles) were provided. This paper describes the prototype equipment and its instrumentation and provides the system characterization results. The future of the Inductive WPT technology is further discussed considering its different technical and economic challenges. In parallel, how this technology could be part of future generation road infrastructures is discussed. Future research and demonstration steps are presented in the conclusion.

“…There are also multiple ongoing research efforts to make WPT a viable technology choice for dynamic electrification. Currently, built prototypes of electrified pathways are capable of sustaining 20 kW of electric power dynamically delivered to a moving vehicle on a 100 m long road segment [138]. However, even with the great advances in materials and power electronics, the technology is still expensive and not fully engineered to large-scale applications.…”

“…In the 1990s, the interest on WPT for automotive applications was definitely recovered with the work of Covic and Boys [151] and, since then, many efforts in this direction have been pursued, with the most representative of them being the FABRIC project [138], as referred in [4]. In this design, a 100-m long track was built to deliver 20 kW of power, to up to two vehicles simultaneously running over it.…”

Nowadays, due to economic and climate concerns, the private transportation sector is shifting for the vehicle electrification. For this new reality, new challenges about operation modes are emerging, demanding a cooperative and dynamic operation with the power grid, guaranteeing a stable integration without omitting the power quality. Besides, new attractive and complementary technologies are offered by the vehicle electrification in the context of smart grids, valid for both on board and off board systems. In this perspective, this book chapter presents a global perspective and deals with challenges for the vehicle electrification, covering the key technologies toward a sustainable future. Among others, the flowing topics are covered: (1) Overview of battery charging systems, including on board and off board systems; (2) State of the art of communication technologies for application in the context of vehicular electrification, smart grids and smart homes; (3) Challenges and opportunities concerning wireless power transfer with bidirectional interface to the electrical grid; (4) Future perspectives about bidirectional power transfer between electric vehicles (vehicle to vehicle operation mode); (5) Unified technologies, allowing to combine functionalities of a bidirectional interface with the electrical grid and motor driver based on a single system; and (6) Smart grids and smart homes scenarios and accessible opportunities about operation modes.
