Charging screen questions

1. Why does supercharging show mi/hr estimate, but charging from a standard outlet or HPWC does not show this info?

2. Why can’t I select a higher charge current on some circuits? For example, I charge at work using an outdoor 110v that uses a 20A breaker, but I can only select up to 12A, despite nothing else tying up the circuit. I used to charge my LEAF with an adjustable EVSE set to 16A and never had an issue. And being a commercial property, you would think the wiring and circuit quality would be good enough for more than 12A...

My guess:

Supercharging rate varies: very fast when your battery is low and very slow when your battery is filling up.

Other non-Supercharging rates are pretty much constant so there's no need to watch for a change in rate.

... 110v that uses a 20A breaker..

Are you using the correct adapter that looks crooked and not nicely parallel?

A good point on the adapter. You are probably using 5-15 (that came with the car), that is why you are limited to 12 A (80% of 15 A circuit). The 5-20 above is an additional order from Tesla store.

Okay, that makes sense now. Thanks for the info!

Right, what kind of adapter you have attached to the charge cable signals to the car the maximum amps it is allowed to draw.

As to the miles per hour number, I thought that would be displaying all the time, no matter the charging source.
