Project Summary

Wireless power transfer for electrical vehicles could reduce the size of EV batteries and eventually electrify roadways broadly, eliminating most centralized charging. The researchers expect to advance wireless power transfer systems through wide bandgap materials, circuit techniques, and coil design. Simple loops of wire would eliminate the need for magnetic materials and reduce the cost of the infrastructure.
