Inductive charging technology


Just turn it off, put it down and recharge it: Induction coils for wire­less charging are already to be found in every electric tooth­brush and have also long been a feature of ovens and mobile phones. The battery is supplied with current via an electro­magnetic field instead of an electric cable. The idea is that electric cars should also benefit from this techno­logy in the future. Induction plates embedded in the ground could provide parked electric cars with power cable-free. Or better yet, the battery would be charged up while the vehicle is driving. Researchers are however still discussing whether the techno­logy is sufficiently effective and suit­able for every­day use to justify the high level of investment that would be required.
