Hi
I have a 2017 Model S which i have owned for almost 4 years. It has the high amperage charger upgrade (~17kW)
I have been charging it on a Telsa Wall Charger, on 3 phase, 240v, perfectly fine in all that time. (I am in Europe)
However, for the last 2-3 months when i plug the car in, the car initially ramps up to 17kW charging. It reads 3 phase, 24/24a and the volatage might be 238v. If i watch it for a bit, it will stay perfectly fine at 17kW until eventually, (it might take 1 minute, it might take 10 minutes) the voltage will briefly flick over 240v and then a message will appear on the dash saying "Unable to Charge. Disconnect Cable and Retry" and the charging speed will drop to 11kW.
A second or two later, the voltage will go back under 240v and the car will ramp up to 17kW again by itself. As soon as the voltage flicks over 240v again, i will receive the same message on the dash about being unable to charge, the charge will go back down to 11kW, however after the second time reducing it does not go back up to 17kW. It just remains at 11kW and stays charging at that rate.
If i unplug the cable or stop and restart the charge from either the screen in the car or the app, it will go back up to 17kW until the whole process repeats.
I plugged into a public 22kW charger to rule out my charger and the same thing happened. (Although that went up to 248v !)
The car had never tripped before. It's only happening in the last few months. I have effectvely lost the ability to charge at 17kW.
I spoke to the Tesla Ranger and he had never heard of that issue.
On goggling, i can't find much, except for someone saying usually charger errors are down to a little fuse that might just cost $10 to replace but Tesla wont repair chargers. They just swap them out for new ones that cost approx $2000 which seems crazy. The local Tesla ranger confirmed this to me.
Has anyone come across this before or can anyone offer an opinion on what might be the issue and if it can be fixed ?
Thanks
