Researchers at Purdue University have developed an in-road wireless charging concept for consumer and commercial electric vehicles (EVs). This technology will enable wireless charging of EVs while driving, without the need to stop to charge. With Purdue's innovation, dynamic wireless power transfer can occur between the roadway and a moving vehicle at greater efficiency than previously possible. By charging vehicles en-route, the effective range of an EV can be increased while reducing vehicle battery size. This technology can be applied to industries where power needs to be transferred wirelessly to moving systems.

Technology Validation: This technology has been validated through testing of scaled down prototypes in a lab environment.
