I talked to Tesla today too. They looked up my charger, confirmed it was currently connected to the Internet, said it looked like the firmware was interrupted at some point (?!) and that they were pushing the new firmware. They said not to charge for the next 2 hrs, and to turn off the breaker, wait one minute, turn it back on before using the charger again.
I was at work when I spoke with them. By the time I got home, it was 3+ hrs later. So I figured that was plenty of time. I turned off the breaker, waited just over a minute, turned it back on, then went to the wall connector to jump on its WiFi and check for the new firmware version. It was exactly the same number as before, 0.8.58, and the hexadecimal hash after the version number was the same too. So I don’t have high hopes for anything different.
I plugged in and started charging. No need to wait, nothing was hot and the day wasn’t that hot. Coincidentally, the car is again at 56%. I’m charging to 80%.
It’s doing 48A right now and said 1 hr 50 min at the start. I expect it to drop to 24A after about 50 minutes, like yesterday. This time I’ll just let it complete rather than try to reset and risk dropping to 6A. I don’t need another late night.
Tesla gave me an “inquiry number” and told me to call back if the amp-limited charging continued. I’ll call again tomorrow if it doesn’t charge at 48A the whole time.
I strongly hope this is software fixable because I do not want to have to replace the unit and don’t want to be out of a home charging solution (even if frustratingly slow) while I wait for a new one.
I really look forward to seeing if new hardware fixes it for you, like
Aweedman. Please update! And I hope everyone here with the issue calls Tesla so they get on the fix! I have faith, I’m just currently frustrated.
