Fast wireless charging of Taycan, 80% in 10 min

[DennisB]

Like the Mission E already showed us, wireless charging our Taycan should be possible in the (near) future.

That is pretty cool and I hope their development work and testing provides the desired results

Would it really? This is for high power DC charging type application (though not sure it it can technically be called DC anymore, since it needs to be turned into AC to be transferred wirelessly). All it eliminates is the need to plug a handle. Convenient? Perhaps, but a game changer? I'm not so sure, especially as it adds further challenges of secured wireless communications, dealing with road debris, mud or snow, metal parts which might have fallen off the car, etc - we all know how much trouble wired plug-and-charge has been to get working reliably, add to it wireless protocols and 300KW wireless power transfer which has to be done safely (that is a lot of power) and it seems like a whole lot of effort for a relatively minor convenience.

The only way I see this being a possible game changer if it's combined with autonomous technology to perform valet functions, i.e. you pull into a charging location, get out and go to a rest stop/restaurant/lounge, while your car drives itself to a wireless charging spot (or into some queue) and once done charging meets you at the curb or parks itself until you are ready. There I can see this being very useful, no need for a "Tesla snake" type application, though I'm not sure which one is easier to design, manufacture, or service - a robotic snake which plugs your car in automatically or a 300KW wireless charging pad AND full proof self driving, be it limited to only within the charger property. Maybe, only maybe, similar benefit if hotels were to get fast wireless charging, the cars would autonomously valet themselves for everyone to get a charger overnight. Notice that this far-out benefit speculation only applies if there are other cars, not just Taycans, all of which can self drive/valet around the property where this is installed, so this would have to be an industry wide game charger, not just Porsche.

Personally I think a 6-20KW residential garage charger version would be more of a game changer. Maybe it's just me, but this seems like a solution looking for a problem. Maybe public transportation vehicle charging while at stops, though I think there is a company already doing this called "Wave".

Making a robot to plug in a car seems way easier. At least for a specific car. It gets more difficult when you have to do it for all EVs and they’re all different.

But I’ve thought about doing this at home just as fun project with the kids. I don’t think you need that snake thing. I was thinking of starting with a 6-axis robot and going from there.

I didn’t get very far though because there’s no way my wife will let me spend the time or money on that. First question I’ll get will be why I have time for this but I don’t have time to fix the garbage disposal. ?‍

while it sounds like a fun project for a talented engineer, I don't think that mass adaptation of such a unit is a good idea.
why over complicate and add more expense to something as simple as plugging a charger into the car?

I was just giving my opinion on the relative complexity of the the two. I’m not advocating either on any scale other than wanting to build one at home.

I would much rather have to place a plug in the car and get faster charging than suffer losses from inductive charging simply so I didn't have to get out. I'm not sure how these guys are managing to get inductive charging as fast as plugged in charging, but I bet the charging curves are not the same.

Bottom line, I would rather have them invest time in getting the batteries to accept charge faster than working on a wireless charger. Or work on a true plug and charge solution like Tesla. What good is this solution if your account won't connect when you pull up ?
