Standardization-Oriented Design of SiC-Enabled Wireless EV Charging Infrastructure for Electrification and Smart Energy Systems

Abstract

Transportation electrification is a central component of future sustainable energy systems, and the large-scale deployment of electric vehicles (EVs) requires charging infrastructure that is efficient, interoperable, grid-compatible, and suitable for standardized deployment. Wireless power transfer (WPT) is increasingly recognized as a convenient and automated EV charging approach, but its transition from laboratory prototypes to energy infrastructure introduces strict constraints on operating frequency, power level, alignment tolerance, electromagnetic compatibility, efficiency consistency, and cross-vendor interoperability. These constraints become especially important when wireless charging is considered as part of smart energy infrastructure rather than as an isolated charging device. This paper presents a standardization-oriented design framework for SiC-enabled wireless EV charging infrastructure in the context of electrification and smart energy systems. Rather than treating silicon carbide (SiC) power devices as isolated component upgrades, the proposed framework connects SiC device characteristics with resonant network design, modular power conversion architecture, standard-aware control, and future grid-facing functions such as efficiency management and demand-response readiness. The framework aims to support fixed-frequency operation within standardized bands, scalable infrastructure deployment across power classes, and consistent efficiency performance under load and coupling variations. A quantitative case study evaluates silicon- and SiC-based implementations under representative standardized operating scenarios. The SiC-enabled system achieves higher efficiency, expanded thermal margin, reduced sensitivity to coupling variation, and improved performance stability across the standardized operating envelope. Loss composition analysis further shows that SiC devices shift dominant losses away from high-frequency switching loss, supporting robust fixed-frequency operation. The results demonstrate that SiC-based wireless EV charging architectures can contribute to energy-efficient, interoperable, and scalable charging infrastructure for future electrification and smart-grid applications.
