It's the opposite of that actually. See this post.Unless you have one of the very early Model X cars that was built, it should be a software upgrade for any refreshed Model S cars and newer Model X cars.
From that same thread, it looks like it is a software update for some facelifted/refreshed Model S owners as well. @Tech_Guy mentioned this about his refreshed P90DL:It's the opposite of that actually. See this post.
Did anyone upgrade from 48 to 72 Amps?
The Model X had some periods of hardware and some of software. When they rolled most of the changes into the facelifted Model S, all of those have been a hardware difference.
My car was ordered with 72amp charger but they delivered it with only the 48 I went to the service center and they plugged in a laptop and flipped a setting to allow the 72amp charging.
I can confirm its a software change, not a hardware one.
It depends on when the car was produced. 72 amp software-limited chargers were a very brief phenomenon. Mine was delivered in June, and requires a hardware swap to upgrade the onboard charger.From that same thread, it looks like it is a software update for some facelifted/refreshed Model S owners as well. @Tech_Guy mentioned this about his refreshed P90DL:
I'm not sure it quite indicates that. I do recall seeing a thread or two here on this forum where there were quite a string of people who had ordered the 72A charger and got the 72A charger when the car was built, but had gotten the wrong firmware in it that was limiting it. @Tech_Guy may have been one of those along with many others. The issue would be for people who actually ORDERED the base 48A charger and the car was built that way. After their car is built, and they change their minds and want to upgrade, what happens then?From that same thread, it looks like it is a software update for some facelifted/refreshed Model S owners as well. @Tech_Guy mentioned this about his refreshed P90DL:

I have a P100d ap2 so I'm assuming it's new enough for hardware.
When you are not at your regular charging location, does the charging screen show 48 or 40? I think it would actually be limited to 48 amps when using a HPWC or similar connector but when using a 14-50 outlet it would be limited to 40 amps.I also have a Model S P100D and it is nominally set to charge at 40 amps (at 240VAC). I was also told that if we pay the money it could be upgraded to 72 amps at any time using the wireless connection. In other words all of the P100D models have the hardware for 72 amps but firmware limits it to 40 amps unless you buy the higher current option. 40 amps is way more than enough for us so I do not ever see buying the higher charging current upgrade.
... but when using a 14-50 outlet it would be limited to 40 amps.
To use a HPWC we would have to pay to get Tesla to enable the higher charging current capability in the Model S as well as purchase a HPWC. Note that I have no way to test the 48 amp capability of the 14-50 since I used lighter wiring and a lower limit breaker than that would require.
Read the red "NOT COMPATIBLE WITH NEW FRONT FASCIA..." - P100D is new front fascia.
Yea, upgrade probably has the "trade-in" value of the old charger included. Those probably become reconditioned parts. Same thing happened with the LTE upgrades, customers were not allowed to keep the old 3G modem.Hardware swap for my facelift S90D delivered June 2016.
I asked if I could keep the original charger and they said "Nope".
