Why not, right? Everything else is wireless, so we might as well go and add electric car chargers to the list.
And that’s what’s happening.
A bunch of firms are developing wireless electric car chargers in an effort to alleviate that EV bugaboo, range anxiety. The thought goes that if there are more places for people to charge their cars and actually go places, the more likely it’ll be for people to go and buy one.
Nissan only sold 510 leafs in May, which is a 55 percent drop from last year, and not an encouraging sign for an EV market that is stubbornly more expensive than its gasoline counterparts.
Will wireless charging stations help? If nothing else, the technology is interesting. The coils that are on the underside of the car interact with the wireless chargers when they’re directly above them. There are two ways this occurs. The first is induction, which is the process that helps you recharge your toothbrush batteries if you have an electric one. The second is magnetic resonance imaging. Inductive chargers require a more precise alignment, whereas the MRI chargers have 10 cm of flexibility.
GM purchased the private company Powermat last year, and is using Powermat’s charging technology now, though only to charge smartphones and other wireless devices in a car.
The city of London is even looking to embed the wireless mats in city streets and parking garages throughout the city.
You probably won’t be able to purchase a wireless charger until 2015, when they’re predicted to sell for over $2,000. The chargers get the EVs to full strength in about four hours; current plug-in methods take anywhere from four to eight hours to get up to capacity.
