It has happened with phones, irons, power tools, toothbrushes and, now, EV charging stations. A sort of rite of passage for most widely adopted tools is that they eventually go cordless but, in the case of the electric vehicle (EV) charging station, going cordless won’t wait. Virgina based Evatran announced that they’ve developed a technology they call “Plugless Power” and they’ve convinced the folks at Google to try it out at their Mountain View, CA headquarters.
Evatran says that the technology is based on electromagnetic induction, a process by which voltage is created by a conductor moving through a magnetic field. It’s a familiar concept in the world of electricity. In fact, all electric motors are based around it but Evatran has tweaked it to work as a new EV charging technology. The process is as simple as pulling up to a fixed charging station. From there, the vehicle charging begins automatically. There’s no cord and no plug to deal with, a convenience that Evatran thinks “is needed for the widespread adoption of electric vehicles.”
To take advantage of Evatran’s Plugless Power solution, EVs have to undergo what is said to be a simple retro-fitting process. For the purpose of this trial run, Google will have one of their many low-speed, short-range electric vehicles retrofitted to work with the Plugless Power station. If the technology catches on, Evatran could end up supplying Google with more retro-fits and more cordless charging stations.
Evatran says that “most” EV and extended range, plug-in hybrids are eligible for the retrofit that would allow them to use the Plugless Power system. Looking forward, Evatran is working with EV manufacturers to incorporate their technology into mass-market EVs by 2012.
