Could VW increase charging speed?

There are various rumors that they will increase to 150 kW and possibly to 175 kW. Search with these numbers, and the threads will surface.
Just consider that while there are some things they can do in software, there are physical limits such as wire and bus capacity, electronic switches and other components, maybe a safety fuse. So while the rumored 175 kW is real, I wonder how much more cushion the car has before it begins bumping into reality.

The real question is how much time do you really have with speed you getting now to do your biological needs...... charging curve is already good enough to have you running and don't have enough time for yourself.
I personally don't like to eat and drive.

Where I am, the EA 150 -350 kW chargers are spaced out over 200 miles apart- more like 220 miles. With the ID.4 AWD range of less than 250 miles, this is a really tight squeeze. I would have to charge to 100% to be able to make it from one EA charger to the next. With the current charging speed of 125 kW, it would take an hour to charge from 5% to 100% (or even longer). I would like to be able to charge from 5% to 100% in 30-35 minutes tops.
Will never happen. Likely the total charge time will stay pretty much the same, but it will charge (a little) faster from 5 to 70 or something.
To be able to charge the AWD ID.4 to 70% and still be able to make it to the next charger, EA 150-350 kW chargers need to be spaced out about 150 miles of each other. That’s not the case right now in most cases.
I would love to be able to drive 2 hours, stop for 20 minutes to recharge to 70% and then drive another 2 hours.
Agreed, that last 10 or 15% is what spikes the charging times. Any general increased maximum speed will have no bearing on whatever percentage range currently is being charged at less than the current maximum.
not saying that you should charge to 70%, but the last part from 80% to 100% is the hardest for the battery to charge, it creates the most heat and it slows down the most during that period, so even if they'll increase the peak charging rate, I won't expect it to be faster in that section. The type of battery used by VW simply can't charge fast from 80 to 100% in a sustainable way
They could raise the charging speed and flatten the charging curve somewhat. They also need to build more 150-350 EA chargers so that one could get from one charger to the next on 70% of battery.

I don't go after EA as preferred network if it's in my trip and if I could reach fine....otherwise i do always try to stay between 10+% and max 6-70% charging. And whatever i come across as Fast DC charging is what I will use.
But everyone is different.... When i use to have custom built ICE cars my full tank of fuel will last about 20-30 minutes on Autobahn in Germany.... feeding 1000+ cc inventory requires a lot of fuel

I planned a trip from GA to QC, and the only chargers 150 kW and above are those by EA and Tesla. If Tesla opens up their chargers to non-Tesla EVs, maybe charging to 70% will make it possible to get to a super charger (EA or Tesla). However, with free EA charging for the first 3 years, I would prefer to stick with EA.
I think it reasonable to assume that the current flat 125 kW part of the charge curve will go to 175 kW, and then decrease to the current levels around 70% and stick to the current curve beyond. I cannot imagine that VW would stress the battery more at high charge levels, where the rate is already fairly generous compared to competing vehicles. VW has a battery warranty and reputation to worry about after all. I'd imagine they're much more sensitive about reputation these days ...
So, as the Tesla increases on Model 3: Sounds great on paper, minor, but still useful impact in practice on the order of 5-10 minutes for a 5-80% charge.
