Recharging your electric car could be as simple as parking
CES 2015 will also showcase WiTricity’s Rezence-Enabled Solutions
Mitsubishi Concept CA-MiEV triples the i-MIEV’s range, adds wireless charging
Mitsubishi's i-MiEV is known for many accomplishments in the electric car world, but long-range driving and staggeringly good looks aren't among them. Its just-unveiled Concept CA-MiEV solves the former by making at least a token gesture towards the latter. The combination of flat-packed, high-density 28kWh lithium-ion batteries and a sleeker, low-drag shape help the compact car last for 186 miles on a charge, or exactly three times what the i-MiEV could muster. It's enough that Mitsubishi describes the concept as a "suburban" EV that could last for a week of typical European commuting on one charge. As it's a showfloor darling, the Concept CA-MiEV naturally stuffs in a lot of technology that's only sometimes related to the battery: it can charge wirelessly using WiTricity's magnetic resonance, takes data from smartphones and will email the owner if it's stolen. Mitsubishi is quick to warn that the car isn't intended for production, like most concepts, but many of the developments found inside should spread to the automaker's worldwide fleet in the long run.

Scientists tweak wireless power transfer, Tesla nods happily in his grave
Wireless charging may be all the rage these days, but actually beaming electricity -- as sketched above by the man Tesla himself -- still has some snags. North Carolina State U researchers have found a way to possibly vanquish the biggest problem: the difficulty of exactly matching resonant frequencies to amplify current. If external factors like temperature change the tuning of a transmitter even slightly then power drops will occur, but circuitry developed by the NC State scientists would allow receivers to detect these changes and automatically re-tune themselves to match. This could make for more potent car and device charging in the future and, if they stretch the distances a bit, maybe we'll finally get the wire-free utopia Nikola dreamed up 120 years ago.
