I have gotten a slightly more powerful version (as in the video) but the main problem is that the coil's inductive resistence is high enough that no matter how much current I make avaliable, the current used is still usually below a few amps. The secondary coil is just a few miliamps.
Mr. Duffy, it is up to YOU to discover that breakthrough for fast charging. I hope you do; you could be the person who finally gets all-electric vehicles into the mainstream. Nothing we've seen to date has done a good job of this.
Thanks. The wireless charger and coils I used delivered about 12V, so you could charge almost anything. The current, however, is pretty low, so it takes a long time to charge batteries. If you have any improvements to the power output capability or efficency of the design, I'd love to see them.
I agree, DRGONZO. It was certainly exciting to see this young man present his project and to see the next generation of engineers at work. I particular appreciated his desire to be innovative by looking for ways to improve the project.
Digital healthcare devices and wearable electronic products need to be thoroughly tested, lest they live short, ignominious lives, an expert will tell attendees at UBM’s upcoming Designers of Things conference in San Jose, Calif.
