Model 3 inductive charging.......

[Mr H]

Not sure on the charge rate but looks promising

 

[Lx2m3]

Think you might have over cooked it!

 

[rotor2k]

Why does it look so drippy?

Why does it look so drippy?

Overdid the snowfoam

Can you do me some Frunk Grocery Hooks? ;-)

I'm waiting until this has been updated

but i will give this a go


Tesla Model 3 Cup Clamp, spring loaded, UPDATED by Designamics

There are hooks for the boot though

You could make a few bob, selling the frunk hooks. Let us all know if you ever do start making them.

Might take a punt on the boot hooks, thanks.

 

[ACarneiro]

Not sure 3D printed ones would be sturdy enough?

 

[Mr H]

Me too which is why i'll wait for my car to do some trials

Reviving an old post that had the correct title - what does everyone think about the possibility of really charging your EV with an inductive charger?
Still in the test phase of development: Technology Overview

 

[Tronguy]

Speaking as a EE type: people look at all these wireless chargers for cell phones and the line, go “How cool!”, note that it seems effective and all that and somehow think that it’ll work well on cars.
In no particular order:

• Speaking of phone chargers, there are a-gonna be losses. One has to go from the source voltage which is DC or 50/60 Hz city power to a couple hundred kHz where coupling antennas work well, then across an air/plastic gap, to another coil, which the energy has to be rectified, then converted back to DC to charge the batteries involved. Yep, it works. But one is going to lose at least 5% if one does heroics on the electronics and more likely up to 20% without the heroics (and cost). Nobody much cares about 5 hours for a cell phone wireless charge vs. 3 or 4 hours by direct electrical contact, heck, one’s probably asleep, anyway. But the car? Um. Time at a Supercharger sounds extreme.
• Safety. There are tried and true methods of getting up to a MW from point A to B, but that’s all with blinking wires, lots of insulation, and staying away from any high frequency stuff. Magnetic charging involves fields. Yes, proper tight shielding between a couple hundred kW emitter and a receiver in a car can make it safe, in the sense that microwave ovens are safe. But this not, by any means, a car driving over a pad or something with an air gap between the car and the pad, then letting fly with some serious high power. People and wildlife will get fried. Maybe in a sealed metal hut with the doors electrically sealed tight? But if the whole point was to make recharging the car more convenient and/or less costly, all of the above seems contradictory. And less safe, to boot.

I’ve read Science Fiction stories where the Aliens had hit upon the idea of passing city power around as microwaves inside of waveguides. Fun story, it could work, but the adapters to our methods of distribution would be.. complicated. And that method had its own set of dangers: everybody learns about staying away from a downed power line at an early age on this planet; the Aliens would have their own set of problems with cracked microwave waveguides.
Short answer: don’t think a wireless charger for a reasonable electric car is going to happen in the next ten years or so. And the safety qualifications for same are going to be Other.

Wireless charging trials were happening in Norway late last year. It may come sooner than you think.

 

[MrBadger]

Successful POC trials already done in UK over many years. Still work in progress though, not from a technology perspective but from scaling and public/commercial viability.

Qualcomm Halo system seems to be quite well established. Latest trials seem to be MOLE TRL | MOLE trials of conductive EV charging

There was also going to be some in road (motorway) trials for charging on the move (likely commercial use only) but not sure what became of them. That was always going to be too expensive for non commercial use and I could never see the digging up of miles of a existing motorway lane a viable trial.

 

[ACarneiro]

Seems like a lot of effort, cost and potential risk for a modest level of convenience.
I tend to be an early adopter but this one is filed under the “meh” category for me…

Have you seen the state of our motorways due to the highways agency? They are literally always dug up.

Comes back to money & demand.

Or a different system on the move:

I thought that too, but Bjørn Nyland videos didn't seem to indicate any significant loss

Uh-huh. OK, if the guy is claiming 98% efficiency and up is "not significant", then I agree.

But the definition of, "significant" is often in the eye of the beholder.. and is flexible depending upon how much money is involved .

 

[WannabeOwner]

I wouldn't pay for one at home if only for the convenience of not having to plug in a cable ... I use a CAT5 cable for network whenever I can rather than use WiFi ... but that's me!

But for in-street charging, rather than trailing cables near to pavement (and no doubt copper-theft will become an issue at some point ...) I was pleasantly surprised that losses seems to be "a couple of percent" ... assuming that will be borne out in reality with rollouts outside of a few carefully monitored test sites
