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?
What a world we live in.
Their sole purpose is to save the auto industry.
But for a premium carmaker the simple solution of “plug in” isn’t good enough when they have to justify the price tag.
I guess that doesn't have the sexy Nikola Tesla factor.
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.
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.
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.
