The max I've seen is about 70 kW, but it quickly gets below 60, then
50, then 40. I've had it checked out by the local service center and
made sure they took the request seriously and they both told me that
it is performing within spec, that they could upgrade the battery to
90 from 70 for something like $22k (new) or less if I was ok with a
battery that was not as fresh (I don't remember the exact definition),
but they told me that they will not guarantee that the work will
improve the supercharging speed. I'm guessing it would, but I also
think it's downright improper for them to ask that I spend that kind
of money, and even be willing to spend more if there's something that
would help address the supercharging speeds, and they just won't offer
it. (And this is a 2015 vehicle.... one would think if there's some
onboard hardware or software that is the bottleneck that it would be
possible to upgrade it).
I may disagree about the value of a battery replacement or upgrade,
though I do think there's an issue there of whether gen1 vehicles can
be revised to handle the latest battery technology. We can't expect a
company to make packs of 18650 cells for dozens of years when they
have moved on to other formats.

I haven't paid attention, but I'm not surprised. Many EV forums I run
across have an issue with Tesla critics and/or sycophants making the
forum somewhat more difficult to use. As for myself, I have mixed
views. They do not balance out to exactly "equal", but I try to give
credit and credit where I think they are due, in all things, and in
the case of both Tesla and its CEO, this results in mixed thinking,
though I guess I have a summary view on certain things. In the
particular case of the issue under discussion (incentives for giving
up vehicles equipped with the free supercharging), I do think there is
possibly (but not definitely) an element of sleaze to Tesla's
throttling some packs to charge at such slow rates that the owner is
incentivized to get rid of the vehicle. That is, they may throttle
the speeds in the name of safety or battery longevity (I'm not sure if
they've actually given a reason), but I question if it's in part
because they want to provide an extra incentive for the owner to get
out of the car. In my case, while I can say a number of good things
about the vehicle and my experience with it, and at one time I had
visions of upgrading the battery and keeping the vehicle for the rest
of my life (and driving around the country free of supercharging
fees), if I do get out of this Tesla it would probably be in trade for
a non-Tesla long-range BEV. There are several reasons for this
including the extremely slow supercharging speeds, the
still-somewhat-inadequate range (compared to what I need), and some
other issues not based on the vehicle itself.
