Electric roads pave the way for smaller car batteries

Sweden’s Chalmers University studies charging on the move

If an electric car charges while driving, the size of the battery can be reduced by up to 70%, and the load on the power grid can be spread out over the day. Charging on the move suits most people, but not everyone. This is shown by a new study from Chalmers University of Technology, Sweden, where for the first time researchers combine the so-called electric road system with real-life driving patterns of Swedish drivers.

The Swedish government has proposed a ban on new petrol and diesel cars...
