A Smart and Sustainable on the Move Charging Solution for Autonomous Electric Vehicles/Electric Vehicles

The growing use of battery-powered transportation entails the development of charging techniques that are autonomous and require minimal human assistance. In wake of this, dynamic wireless power transfer (DWPT), or dynamic wireless charging (DWC), is a promising solution for intelligent transportation systems (ITS). DWC can make the charging process autonomous, reliable, and convenient, which is pivotal to ITS and smart cities. To bring this to fruition, this study proposes the design and development of a DWC test bed using a copper tube and a Class DE resonant inverter whose consolidation aspect had remained unstudied before. Experimental results validated a strategy for enhancing the inductance, magnetic field strength, and Q-factor of the copper tube. The Raspberry Pi Pico is used as the primary controller for the WPT system. To achieve optimal performance, high-frequency (HF) inverter MOSFETs with low Rds (on) are selected. The experimental results were substantiated with 12 watts of power transferred at a distance of 0.55 meters and 25 watts at a distance of 5 inches using the proposed approach. The DWC system is also provisioned with added intelligence in order to actualize the concept of ITS and smart and qreener cities.
