Imagine never having to plug in an electric car to recharge,but instead simply take the highway on-ramp to get a range boost.

Researchers from Stanford University have published a new demonstration of highly efficient wireless charging that could allow the technology to one day be scaled up to boost driving range of electric vehicles on highways of the future.

Wireless, or inductive, charging – the same technology that is nowadays often used for electric toothbrushes and some smartphones – is under development and being piloted by some car makers already.

But current electric car inductive technology has its limitations: it relies on charging pads that must be aligned perfectly with the oscillating magnetic field that transmits the current to optimally recharge the vehicle, and of course the subsequent downtime to recharge.
