This would be a neat way to charge a rav4ev

Other variations of this exist and it is inefficient so if you like to loose even more power while charging then this is perfect. Not to mention the higher the ground clearance the worse it gets.

From what I can see it has contacts, so no losses at all, just like a j1772 plug

Looks inductive to me. The magnet just elevates for better efficiency.

from the text in the article



It extends an arm that attaches to a unit underneath the vehicle. There, it charges using a conductive charging method: metal touching metal.

Sounds like vaporware since it is not even available yet. I also would not want that thing on my garage floor. Anytime the promo video is animation it seems very fund raising like.

So first you make a wrong assumption, and when I point that out it is vaporware.
You seem like a grumpy person.

It might actually be vaporware, but like I said in the topic when I started

"this would be a neat way to charge a rav4ev"

Yes it looks like it is conducting the induction. Need multiple contacts vs a flat disk as shown.

We will know more once it is actually available.

In the youtube animation , a lid slides away from the contacts under the car.
The disk could contains several circles with contact layers.
It could be similar to J1772 plug :
have big contact points for the power, and smaller for the data communication.
Only when the communication is successfully established, the contacts are closed to provide the power.
Just like J1772.
If you would have a center pin, you could make sure the contacts are neatly aligned.


There is a FAQ on their website, and you can already reserve one:

Oh and this explains how it works:

So it is a complete J1772 like implementation.
You could just hook it up in parallel in your car with the current J1772 inlet.
Up to 13kW

Grumpy? No I just have seen plenty of these products that are not shipping but just looking to raise money to build or tool which shows they are not ready for market. Regardless of how it connects it would need to be very well built to be reliable and durable and even a $1500 unit seem low cost for a launch. Additionally, how practical is it to have a big lump on the garage floor you can trip over? The car also needs to be relatively close to the unit restricting parking options for some to a specific area. To me plugging in is not that difficult and better than something that would get in the way and could break down . I don't see these devices to be practical for mass use unless they are flush mounted and very reliable. Since it is not a proven or available product at this point then it's a neat concept not a neat product available to purchase and it sounds like they may be testing prototypes not production units. UL listing this will be quite an expensive task as well because it needs to meet a variant of the EVSE standards plus it resides on the floor. Good luck to them as it's a costly product and they should be charging more as it will be for a select market that would pay more if it worked reliably.

Now we are back to a technical discussion, and I fully agree with you on all the points you made ! ;-)
