Radio waves pave the way for better wireless EV charging

Imagine parking your electric vehicle (EV) and charging it without plugging in a cable. Wireless charging makes this possible, but efficient charging requires precise alignment between the vehicle's receiver coil and the charging pad. Researchers at the University of Osaka, working with Tokai Rika Co., Ltd. and the University of California San Diego, have developed a technology that could help vehicles do just that.
