Making Electric Vehicle Wireless Charging Systems A Reality

As electric vehicle (EV) adoption for both consumer and commercial purposes rapidly grows, so does the need for improved charging infrastructure. In the past several years, the industry has seen vast improvements in charging technology, leading to charging times rapidly decreasing from eight hours for a full charge to less than 30 minutes with newer optimized chargers and vehicles.

This huge reduction in charging time is especially impressive considering that vehicle range has also greatly improved at the same time. But as additional regulations on combustion vehicles are implemented and more commercial EVs, including heavy- and lightduty trucks and busses, are introduced, further EV charging innovation is needed.

Currently, wireless charging is the newest EV charging technology evolving. In this white paper, we explore how wireless charging works, identify the challenges presented by wireless charging of EVs both at a system and a component level, and discuss how Knowles Precision Devices’ components can help address these challenges so that you can make widespread wireless charging a reality.
