This new charging system doesn't work by magic, but by induction. To recharge an EV with this system, the vehicle pulls up to the charging station and parks over a floor-mounted parking block. An adapter fitted to the vehicle and the parking block both contain metal coils that become aligned by magnetic sensors. The control tower for the charging station converts electricity into the right frequency for the charger and when the coils are aligned, the electricity creates a strong magnetic field in the parking block's coils that induces a flow of electricity in the coils in the vehicle's adapter, which charges the battery.
Induction is what's used in electrical transformers and has been used for charging smaller devices like cell phones and electric toothbrushes, so it was only a matter of time before we saw it used in EV charging.
The company is running a pilot program throughout the year and hopes to commercially release the system next April. So far, Evatran has been able to achieve an 80 percent efficiency with the induction charging, but hopes to hit 90 percent by the time production units are released.

Hi Ken,
ReplyDeleteVery interesting! I know my comnpany is working on a cordless power initiative for household appliances but didn't realize that the technology could be extended to cars. Pretty cool stuff.
Best,
Marty
Okay -- don't even talk to me about technology right now. I'm still lost in Windows Hell. Grrrr
ReplyDeleteNice. That will be a big plus. It works great for my toothbrush, so it stands to reason it will work great for us.
ReplyDeleteHave you heard the idea of lining highways with magnetic strips so you can charge up your car while you drive, and generate lots of additional power, too!
Also great!
