Because battery technology still relatively sucks, electric vehicles like buses that have to run all day long usually stay tethered to a spiderweb of overhead cables. But as an alternative to that costly infrastructure, researchers at the EPFL have developed an electric bus that can recharge itself at every stop in as little as 15 seconds.
Converting a city’s surface road mass transit system still requires the charging stations to be installed at specific stops along given bus routes, but it requires far less of an investment than stringing up and maintaining overhead power lines, or tearing up the streets to installunderground inductive charging cables.
