WiTriCity Wireless Charging Gains Momentum

witricity

Plug-in cars are only just starting to sell in serious numbers, but one company that aims make that nomenclature obsolete. WiTriCity has already proven the potential of wireless “inductive” charging, and they hope to increase the rate of charging beyond what is possible even in today’s advanced EVs.

Whereas most EVs have either a 3.3 or 6.6 kW onboard charger, WiTriCity has announced that it plans to increase power transfer to “10s of kilowatts” reports Green Car Congress. Their patented wireless charging system has up to a 95% transference efficiency. This could allow EV and PHEV drivers to recharge in just an hour or less, without ever even having to get out of their car (though that might be kinda weird).

Why should you take WiTriCity seriously? Well Toyota certainly is, and the upcoming Prius Plug-in will be compatible with the WiTriCity inductive charging system. Indeed, the ability to install and (more importantly) hide these wireless charging pads in plain site makes them adaptable to many different environments and areas. While it won’t happen overnight, WiTriCity says it is prepared to march side-by-side with the battery industry as capacity and range both grow as well.

The vehicles that stand to benefit the most in the next few years though are plug-in hybrids (ironically enough), which tend to have smaller batteries that take less time to recharge. The ability to park, go shopping, and return an hour later to a topped-off hybrid is a compelling notion, and subtracting the plug park only makes it that much better.

Who knows…maybe one day, car charging stations as we know them will be sought after as prized relics of a long past time, when people had to plug in their cars for themselves.

  • For a home, this makes very little sense. Maybe in public charging situations?

    I am really not sure what the attraction is for wireless charging. Especially since it is lower efficiency, almost by definition.

    Just take the 9 seconds to plug it in.

      While it may not replace all plug in situations (I am thinking DC fast charging for cars with bigger batteries) anything that helps to make them more convenient will help to speed the adoption of EV’s.
      I have read that one of the aspects of having an EV that women really appreciate is no more stops at the gas pump. So for them to just pull into the home garage or driveway/parking space, or when out in public the right parking spot and have the vehicle just start charging, will help to increase the desire and speed acceptance of EV’s.
      With the efficiency factor now at 95% (and like with any tech, likely to improve), the small amount of loss is likely to be well balanced by the convenience factor.
      Also for anyone there are the times when the weather is bad and you just want to run from the car to the home or store or job, or if you are running late. To have your vehicle just start charging automatically will be seen as quite a plus, thus help speed adoption.
      Lastly the use of this type of charging will help to keep batteries constantly topped off, rather than the big cycles from full to empty, so will help to extend the usable life of the packs
      While for some the nine seconds to plug in (or maybe more practically 30-60), may seem a none issue, anything that helps make EV’s a better value than ICE vehicles should be accepted with tolerance. Because for some these features will be of high value, and help to encourage the conversion off from fossil fuels which is really the important issue.

      I agree 9 seconds to plug in and 9 more to unplug works for me . The slight loss in efficiency involved with wireless charging would be acceptable at my house. Having the car automatically recharge every night with no operator actions is so much more reliable since you don’t have to worry about “Forgetting” to plug in. This resolves one more question I almost always get from non EV owners “What do you do when you forget to plug in” .
