Evatran's Plugless Power wireless EV charger gets smaller, conscripts Chevy Volts for testing
When it comes to technology, the old adage of "bigger is better" died a long time ago, so it's not a surprise to see "smaller is smarter" thinking apply to products and prototypes across the board. Today's (relatively) tiny wonder is Evatran's Plugless Power electric vehicle charging system: now smaller, more efficient, and primed for its first trial phase. The last time we saw Plugless Power, the system's wireless charging "station block" stretched nearly the length of a full vehicle and charged at 80 percent efficiency. Today the charge block is only slightly larger than an average hubcap, boasts a 97 percent charging efficiency, and is less picky about your car missing the wireless charger's "sweet spot." Evatran is now working on launching a test fleet of up to 12 Chevy Volts to put the system through its paces, and hopes to expand the tests to as many as 30 vehicles by January. Ready to ditch pumps and plugs forever? Start saving: a complete Plugless Power system (including vehicle retrofitting) will set you back as much as $5000 after production starts sometime in 2012. Don't be too surprised, cool stuff rarely comes cheap -- besides, that old adage has to apply to something, doesn't it?
Evatran's Plugless Power gives your wheels a wireless proximity-based charge
Trading gas nozzles for electric sockets may be the green thing to do -- in more ways than one -- but wouldn't plug-in hybrids and electric vehicles be that much sweeter if you could just forget about the plug? That's what Evatran is trying to do with its Plugless Power technology, shown off at Plug-In 2010 in San Jose, which charges your car automatically when you pull up to the company's specially-designed curb. The "station block" above is a wireless induction charger (yes, a car-sized Powermat) that beams electricity to a shoebox-sized device you mount to the undercarriage of your vehicle, magnetically detecting and gravitating towards said shoebox even if you park somewhat crooked. The system presently works with 80 percent efficiency when firing electrons across a two-inch gap (engineers are shooting for 90 percent by the time it hits production) but of course the base station itself doesn't get power from the ether -- it requires one of the company's own Level 2 wired chargers (and compatible wiring) to run. Should your residence or place of business be equipped, the 240 volt towers will set you back $3,245 this December, and the proximity charger will be available to early adopters in Q2 2011 (we're hearing April) for the bargain price of $800.
