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.
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?
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.

So upselling a supposedly “green” product by throwing away a sizable portion of energy while charging it.
What a world we live in.

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.
