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.

I thought induction has big losses and heat generation?

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.
