Dynamic Wireless Power Transfer Charging Infrastructure for Future EVs: From Experimental Track to Real Circulated Roads Demonstrations

Abstract

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.

A Measurement System for the Characterization of Wireless Charging Stations for Electric Vehicles

“…Synchronization occurs by setting, on each unit to be synchronized, the same instant of acquisition t 0 (e.g., 11.00.00 A.M.). The operator of a unit must communicate to that of the other units the moment of acquisition chosen, and this normally takes place about 1 min before the acquisition.…”

“…The latter is unified at 85 kHz for light vehicles [9], [10] and decreases for heavy vehicles. A more futuristic version of WPT charging is the dynamic one (DWPT), which provides for charging with a moving vehicle, for example, in a road lane [11], [12]. However, DWPT needs the measurement of power and efficiency in sequences of rapidly changing regimes, which is outside the scope of our investigations.…”

A Review on Power Electronics Technologies for Electric Mobility

“…Despite all these technical difficulties, DIWPT was soon recognized as a promising research effort, attracting the contribution of many groups around the world, among them [148][149][150][151][152]. More recent projects, involving both scientific and industrial partners, such as the FABRIC European project [153][154][155][156] have further advanced the technology. However, the proposed solutions are complex, and so are their cost, which is still being fully assessed, and represents a major challenge for the widespread adoption of the technology.…”

A Reliable Sensor Network Infrastructure for Electric Vehicles to Enable Dynamic Wireless Charging Based on Machine Learning Technique

“…However, the costly model implementation and high magnetic field of aforestated model creates health issues, which minimizes its used in the real environment. Laporte et al [30] proposed the track built based dynamic wireless charging infrastructure for electric vehicle. They used specific roads, which were contained with electric pad to transfer charge to EV in wireless fashion.…”
