Japanese manufacturer Nissan has ambitions beyond wireless charging bays, as it devises an inductive charging system capable of transmitting power wirelessly over longer distances.
It is exploring scaling up the concept for use with its electric car. The idea is that it could theoretically be used for on-the-go recharging, alongside a grid recharge at night.
With traditional magnetic induction, conductive coils are used to transmit power wirelessly over very short distances - the coils must be very close together although they do not make direct electrical contact.
Inductive charging has already been used on a number of earlier electric vehicles including the Nissan Hypermini and GM’s EV1. However, Nissan hopes to scale up the technology with a series of plates that are laid into the surface of designated electric vehicle lanes on roads and motorways, helping motorists to charge as they drive.
The manufacturer admits it has no idea how much the idea would cost or how long the designated lane would have to be, but is said to be ‘grappling with consumer research’ that has revealed that 61 per cent of potential electric car customers are most concerned about the inconvenience of recharging.
However, David Bott, a director of innovation programmes at the Technology Strategy Board, is sceptical about the idea of charging lanes according to a Guardian report. He states that while it’s scientifically feasible, whether it’s scalable or not is “another matter”.
