But charging moving vehicles with high-power wireless chargers below them is complex.<\/p>\n<p>Researchers at North Carolina State University have developed a way to deliver power to moving vehicles using simple electronic components, rather than the expensive power electronics or complex sensors previously employed. The system uses a specialized receiver that induces a burst of power only when a vehicle passes over a wireless transmitter. Initial models indicate that placing charging coils in 10 percent of a roadway would extend the driving range of an EV from about 60 miles to 300 miles, says <a href=\"http:\/\/www.ece.ncsu.edu\/people\/smlukic\" target=\"_blank\" data-ls-seen=\"1\">Srdjan Lukic<\/a>, an assistant professor of electrical engineering at NCSU.<\/p>\n<p>Wireless charging through magnetic induction\u2014the same type typically used for electric toothbrushes\u2014is being pursued by a number of companies for consumer electronics and electric vehicles (see \u201c<a href=\"http:\/\/www.technologyreview.com\/news\/429163\/wireless-charging%E2%80%94has-its-time-finally-arrived\/\" data-ls-seen=\"1\">Wireless Charging\u2014Has the Time Finally Arrived?<\/a>\u201d). Such chargers work by sending current through a coil, which produces a magnetic field. When a car with its own coil is placed above the transmitter, the magnetic field induces a flow of power that charges the batteries.<\/p>\n<p> <\/p>\n<p><a href=\"http:\/\/www.technologyreview.com\/news\/521761\/someday-your-ev-charger-may-be-the-roadway-itself\/\" target=\"_blank\">Read more <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A researcher envisions the ultimate cure for \u201crange anxiety\u201d: roadway-powered vehicles with modified on-board power receivers.
