Field-Focused Load-Leveled Dynamic Wireless Charging System for Electric Vehicles
Project Innovation + Advantages:
Cornell University seeks to develop a breakthrough wireless charging system for stationary and dynamic charging of EVs that will drastically reduce the need for expensive and bulky on-board batteries, enable unlimited range, accelerate EV penetration, and reduce U.S. energy consumption. The new system will leverage charging range extension, field focusing, and machine learning-based optimization to (1) reduce interference from fringing fields by 10x, (2) increase energy transfer by 10x, and (3) reduce power pulsations by 10x compared with state-of-the-art solutions. The project will demonstrate a 50-kW capacitive wireless charging system for EVs, which targets 150 kW/m2 power transfer density and 95% efficiency, while meeting fringing-field safety standards and minimizing power pulsations on the electric grid.
If successful, this project will advance the development and evaluation of an intelligent energy management system that enhances operational reliability, lowers infrastructure costs, and achieves higher economic benefits for the system operator and EV charging service provider.
