Wireless-induction charging of vehicles and plug-in hybrids is likely to become common within the automotive industry say EV experts. “We believe it’s not a matter of if but when wireless charging will be in all (electric) vehicles,” Laura Marino of the Oak Ridge National Laboratory stated during a recent Automotive Power Electronics conference.
Inductive charging will become very popular strictly because of convenience. With this type of charging, one would not have to remember to plug in the car after use. Inductive charging sends electricity wirelessly between two coils. One coil would remain inside the car while the other could be hidden under a garage floor or city street.
What makes induction charging so convenient is that charging points can be built into roads close to stop signs. Furthermore, the Logan Airport in Boston will implement the technology into shuttling travelers to and from car rental agencies. The induction chargers will be embedded into areas where buses wait for passengers. This allows the bus to charge while waiting for more passengers.
In Europe, the automotive industry has not yet agreed on a standard for plugs. The development of electronic vehicles relies on the cost of infrastructure meaning low cost production is of importance. Renault is arguing for a system based on alternating current. This will hopefully lower the cost of building charging points. Some estimates predict a direct- current fast charge point would cost $70,000.
