I am not concerned about plug and play, the time savings is insignificant. I'm more worried that there could be some coding that will not allow this age of vehicle (early 22 models) to charge using an Tesla approved adapter. We'll just have to see how this plays out.
After gathering all the info I can to this point.
Please correct any wrong info in this post, I'm not a Wikipedia.
Just general numbers and guesses below.
It's looking like Tesla charger versions 1 and 2 will never work for anything but Tesla.
Tesla may leave it that way as a small perk to Tesla buyers.
But after all the new installs with tax credits are completed, they will probably swing back around to update the older version chargers.
Tesla has little incentive to update their older chargers right now, or even over the next 5 years.
It's a race to install the most chargers and get the tax incentives.
Even though it appeared Tesla had allot of chargers before they started version 3 and 4 chargers, it's a drop in the bucket compared to the numbers of chargers being installed today. 235 fast chargers "CCS1 and NACS" per day for the next 5 years. I believe Tesla currently has 25% of all the fast chargers today.
I believe Tesla is planning to charge higher prices for non Tesla, but there is no way to charge Tesla drivers higher fees at non Tesla chargers.
If you want to see only Tesla chargers that will be available with this adapter, go to ChargePoint and sort NACS connectors 250kw and above. Today it wipes out about half the Tesla chargers. But in a few years Tesla will have added so many version 3 and 4 chargers, that level 1 and 2 chargers will be less than 10% of the Tesla chargers out there. At that point Tesla may circle back and upgrade those older chargers.
