Tesla Motors Club
My wife's MS 100D (her 2nd MS) which has 51k miles in 15 months has been tripping the Tesla home charger.
Our power has always been iffy and normal charge would be set to 40 Amps, but with her previous Model S (185k miles in 5 years) we lowered it to 30 Amps because our power would drop below 200 volts and the charger would go 'red'. That worked well for the 5 years. Plus she never needed to charge any quicker.
New MS 100D - We continued that method - setting it to charge but only at 30 Amps. But, we have been getting Faults from the charger which cease (middle of night of course) and she winds up with insufficient miles to get to work - I wind up running to nearby Supercharger to get her to work.
What we have noticed is that the car sets itself to 72 Amps shortly after she plugs in and sets it to 30 Amps ??? Setting it back to 30 Amps would make it stay - but maybe it is resetting to 72 later in the night? I believe this is causing the problem - making the home charger max out at 40 Amps and it fails when night voltage drops.
Ok - I have a M3, and although I normally charge at home with a 110v outlet (dedicated circuit in Garage - nothing else connected) as I normally drive less than 50 miles/day). When she is out of town (weekly) I will connect my Tesla to the Home Charger and charge at 30 Amps - never had a problem. Even when I occasionally need to charge 200+ miles.
OK - baffled.... do I suspect her newer MS or the wall charger?
