Anyone know how common this is (Tesla destination chargers set to "Tesla only") in the US? @daveo4EV perhaps? Up until I read this post I was under the impression that TeslaTap would allow charging at all Tesla destination chargers, no fiddling required.When Tesla install destination chargers, they usually install three. 2 x Tesla only ones and 1 x any EV. The Tesla only ones are Type 2 chargers but have been set to only work if a Tesla is plugged in. I am unsure of the exact mechanism the charger is capable of detecting its a Tesla, but they have a way.
The Tesla only chargers will have a red sign saying "Tesla Vehicles" and the other charger will have a white sign saying "Electric Vehicle" - which is how you can tell them apart. You'll see the red Tesla only sign behind me in my picture.
This can be disabled by opening up the charger and setting some DIP switches to convert it into a Type 2 charger that will charge any EV. Some chargers overtime, seem to have these settings flipped as hotels don't really care and probably increasingly want their chargers to be more versatile now that there are a lot of EV brands turning up at their door.
I have discovered that if the DIP switches aren't set, you can *sometimes* trick the charger to start if you reset it a few times and have your Taycan plugged in while its rebooting. After a few attempts it can work – seems like there might be timing issues with the vehicle detecting code.
So when I said "coax" that is what I did in this case!
