Sitting in the passenger seat of the wife's Macan 4S EV right now. Installed 11.2KW charging for it. Had to stop at a super charger for 15 minutes as we had to take an unexpected long trip today and she never plugs it in until the car is at 30%. I would 100% install this in the floor. You park in the garage and it charges. It is perfect.
There are pretty clean combustible sources out there or even alternative electrical sources out there, but somehow humanity has gone with big, heavy, rare mineral hungry batteries.
What's the deal against hydrogen? Toyota made a car that made it to market, it can't be that dangerous if it was sold in certain regions with extensive safety testing procedures. I know the problem is getting hydrogen at the pump station but other fully battery dependent cars have had that same issue before.
I'm sure hydrogen has other problems but what about ethanol? Better than gasoline, no? At least 40% less greenhouse gases out of the tail pipe, and its production is pretty mild for the environment compared to batteries. It wouldn't make cars that much more complicated either, and you could "easily" convert your ICE car. Hell, there are others.
Such a weird set of events dictating the future of cars ngl.
I wonder about unexpected side-effects of inductive charging.
Less efficiency is one thing.
But what about the magnetic fields? I notice some EVs have pacemaker warnings due to the magnetic fields. Would this be a similar situatuon? And would it erase the mag strip on your credit cards?
Working at this scale and price tag, it seems like it would be easier to install a small robot arm in the floor to do it. Or a setup like a 3-axis milling machine, just to align with a port on the bottom and plug it in.
I guess that doesn't have the sexy Nikola Tesla factor.
This is an absolute waste of weight and nothing more than a presser tech demonstrator.
Given induction's fundamental (physics) limitations, there's zero chance this will make it into a production vehicle.
The energy storage requirements and practical charging speed of a car are not remotely the same as for a portable electronic device such as a phone.
Human passenger EV charging will always be through a direct cable connection.
If you want something even faster, just do an automated physical battery swap and design the car's physical safety envelope and grounding systems around this additional access affordance.
11 kW is just fine - it means the car will be fully charged every morning after an evening in the garage, and wireless means you'll never forget to plug it in.
I don't disagree. My EV charger is even slower (only 30A), and it's more than enough. It also only cost $250 and uses a standard 220V plug in my garage. I suspect the Porsche solution is much, much more expensive.
Taking five seconds to plug in isn't a big deal to me. However, my wife (with her own separate EV) does often forget, and it's a bit maddening at times. Of course, we have a long enough cord that we can park in different places and always charge, so a wireless charger wouldn't fix the problem if we had to switch around to use it.
Charging has just got "reasonably" short at maybe 15-30 minutes and with inductive charging the charging industry goes back 5 years in term of time needed to charge.

So upselling a supposedly “green” product by throwing away a sizable portion of energy while charging it.
What a world we live in.
Does anyone still believe EVs are here to save the world from climate change?
Their sole purpose is to save the auto industry.

Their sole purpose is to have an excuse to stop poor people, who can't afford changing their old petrol cars, from driving.

I thought induction has big losses and heat generation?
It does. And very tight alignment requirements.
But for a premium carmaker the simple solution of “plug in” isn’t good enough when they have to justify the price tag.

Wireless charging is in production. Here's one example:

Wireless charging can be as efficient as wired charging:

Induction charging made it into production vehicles in the past [1], so always is a little bit too strong.

While it's neat, it's not that fast (same speed as a 60A Level 2 charger). The advancement we really need is hot swappable (and affordable) spares.
