As the green car segment looks to new ways to bring more potential drivers into showrooms to consider purchases of vehicles like the Chevy Volt and Nissan Leaf, one strategy we are seeing with increasing presence is the idea of wireless charging. This methodology, which usually involves a modification to the car so it can receive energy from a wireless charger it parks over, was recently showcased in Utah for mass transit. Now comes word Momentum Dynamics (MD), founded in 2009 and based in Pennsylvania, has successfully charged a Volt using its wireless charging offering.
MD noted its wireless charger is capable of offering up more than 20,000 watts of power, which more than what’s provided by a regular, 240-volt Level 2 plug-in charger. The advantage here, the company points out, is that it allows for reduced charging times. In the case of this technology, in consists of a simple receiving pad installed on the underside of a vehicle, and a transmitting pad placed on, or embedded into the road surface.
Though MD’s primary focus seems to be wireless charging for the commercial market, it recently scaled back its technology to meet what it terms the more “modest power requirements of passenger EVs” in its experiment with the Volt. It did this to prove to “the industry that wireless charging can be rather easily integrated into current production EVs.”
As was previously mentioned, wireless charging of electric vehicles isn’t new, but it isn’t exactly something every EV driver has embraced yet either. For one thing, it can tend to be more expensive as an after-market option right now versus regular plug-in chargers. Still, there’s a lot going on in this developing technology, with GM showcasing a few years ago a Volt being wirelessly charged by a Powermat setup. Also out there in the process has been Evatran, Volvo and Stanford University, among others, researching how to bring this to market.
“We do for EV charging what systems like E-ZPass have done for automated toll collection — except in this case it’s about more than reducing toll gate congestion — [and] we are actually enabling the growth of an international industry,” said MD CEO and co-inventor Andy Daga in a statement.
