After update charging?

[Choochoosparky]

Just got the update on my '15 70d, and I only charge with a 110v, but I would charge at 4kW before, and now it bounces between 1-2kW/hour. This happen to anyone else or even notice a difference in their charging?

Are you sure about that? 110V charging at 4kW would imply a 37A current. From what I've heard level 1 charging maxes out at 1.9kW, so it's most likely that either you're remember things incorrectly or the screen was glitchy. It sounds like 1-2kW/hour is the correct rate when charging with a 120V/20A line.

120v, not 110.

You've never charged at 120V / 4kw with any adapter that Tesla provides.

120v at 12 amps (using the NEMA 5-15 that comes with the UMC) is ~1.4kw.

120v at 16 amps (using the optional NEMA 5-20 adapter available for the UMC) is ~2kw.

Yes sorry 120v. I'm just going off what the screen said everytime I charged pre-update...

I just searched for it and couldn't find it, but I remember someone else on this forum having the exact same confusion with the exact same numbers for the exact same reason.

You didn't look at the units. 4 would be about the charging speed when it's displaying the "miles per hour" format. Between 1 and 2 is the charging speed when displaying the power level in kilowatts. A software update can sometimes flip a setting here or there, which is probably what happened. Go into your settings display, and you can pick the option for energy units to be either in "Energy" or "Distance", and it will switch those units on the charging screen.
