Adaptive Coil Configurations for Efficient Dynamic Wireless Charging in Electric Vehicles
Keywords:
Adaptive coil configuration, Dynamic wireless charging, Electric vehicle, Wireless power transferAbstract
This study aims to explore adaptive coil configurations for improving the efficiency of dynamic wireless charging in electric vehicles. Dynamic wireless charging offers a promising solution for reducing dependence on static charging stations, but its implementation remains challenged by misalignment, power fluctuation, transmitter segmentation, vehicle position detection, and infrastructure readiness. This research employed a qualitative exploratory case study approach to understand how technical actors interpret, select, and evaluate adaptive coil configurations in real implementation contexts. Data were collected through semi-structured interviews, non-participant observation, and documentation involving 12 to 18 informants, including wireless power transfer researchers, electrical engineering lecturers, engineers, laboratory technicians, charging infrastructure developers, transport managers, and policy analysts. Thematic analysis identified four main themes: technical efficiency as a design priority, misalignment as a field-level challenge, segmentation and position detection as control requirements, and implementation readiness as a socio-technical concern. The findings show that adaptive coil configuration cannot be understood only as an electromagnetic design issue. It also involves operational reliability, sensing accuracy, safety, maintenance feasibility, cost, and institutional coordination. This study contributes theoretically by expanding the understanding of dynamic wireless charging as a socio-technical system. Practically, it suggests the need for coil designs that tolerate positional variation, reliable detection systems, and infrastructure planning that supports scalable implementation. Future research should integrate qualitative findings with experimental testing to strengthen evidence on adaptive coil performance.
