Course title: Advanced Wireless Charging System for Autonomous Electric Vehicles
Details: This presentation outlines the development of an advanced wireless charging system for autonomous electric vehicles (EVs). With global bans on internal combustion engine vehicles accelerating EV adoption, a robust charging infrastructure is essential. Wireless charging offers significant safety and integration advantages for autonomous EVs compared with conventional plug-in methods. However, widespread adoption faces challenges, including limited compatibility across vehicle models, diverse chassis heights, misalignment during parking, proprietary communication protocols, and high costs. The proposed solution decouples control and physical layers, enabling non-invasive fast installation, broad compatibility with varying vehicle designs and parking accuracies, and eliminating the need for EV software updates. Innovative system design further enhances misalignment tolerance and installation flexibility. Real-vehicle tests demonstrate a very high DC-DC charging efficiency across the long transfer distance (up to 245 mm). This system aims to make wireless charging accessible, safe, and effective for all autonomous EVs under any condition.
