My only experience with Tesla’s Autopilot is reading about it and watching youtube videos. And reading crash reports.
I see... if you’re in the LA area during a charging stop and want to try it out for comparison, just let me know. Thanks for sharing this experience with us prospects!

the cheat sheet is easy - amp rating of the plug * 80%… :)
Guessing if the Porsche Universal Mobil Connector (that is a thing, correct?) is anything like the Tesla's, one plugs it in and the electronics check the circuit and use or limit accordingly up to 80% of the circuit rating. The resulting amperage shows up on my screen.

Basically, I’m just repeating: Drive for 3 hours, charge for an hour or so.

I’ve been on the road for 10h05m and covered 403 miles. 0.435kWh per mile. Not bad, but significantly less than I could do burning liquified dinosaurs.

Nicely, the car knew I was stopping off at a DC Fast charging station, and it pre-warmed the battery as I approached. Not that it mattered, as it was a mere 50kW station. The pre-warming only really matters for 150kW or 350kW stations.
I no longer have a " drive for 3 hours" capacity. :blush:

The Tesla charges rapidly from a low state of charge (SOC) (5 or 10% to about 50%); maybe 15 minutes. So on road trips I rarely (unless absolutely called for) charge much higher than that. In fact, I take the charge/mileage necessary for the next stop and add a 50 mile cushion and go instead of waiting for a higher charge to make the next following point of charge. Your battery architecture (800volts vs 400volts) allows a more rapid charge. I still wonder what would happen if you just charged to about 50% or wherever the charge starts to taper off (if it does) and head (rapidly to the next charger)? Break up the drive with shorter stops. I can cover 625 miles in 11h08m (give or take).

Maybe that is not economically possible either as I don't know whether you are charged by Kwh or flat rate or some other combo.

Great pics! (P4NTHA has been added)

Early morning run to the Central Valley to see my sister and her offspring.

Grabbing a quick electricity fix...

I see you stopping at places that aren't Electricfiy America, are these chargers free or do you have to pay?

About the dryer plug, is this what you bought? Thanks

In the USA, you probably should always have the 3 prong adapter and a 4 prong adapter. Homes built before 2000, tend to have the 3 prong, and those after 2000 have the 4 prong. To me any EV user going to visit relatives or friends should have this, together with a a 30 to 50ft extension cable so you can reach the dryer plug and mooch your relatives or friends electricity

Well problem is the unit can not know the “circuit” rating. it can know from the kind of plug what it can handle (like the NEMA 14-50 means 50amp). But it can not tell if you use an adapter and plug it into a 40 amp circuit. If the car (like Taycan) wants 40 amp and it can provide it it will draw full 40, which is 100% of the rating. It may trip the circuit and/or is beyond safety rating. You can limit the current in the charger and in some cars in the car itself to a maximum in that case.

Not even Tesla “magic” can determine what the circuit it is plugged into.

Well, I am learning all sorts of things on this forum. The latest Universal Mobile Charger is different than my generation 1 model. The manual seems to imply it checks circuit based on the plug inserted (e.g. NEMA 14-50). Will have to check auto manual as I know something adjusts amount of amps drawn based on something. I have a 50 amp fuse so my connection will allow up to 40amps but I have seen it adjust downward for whatever reason. You've burst my bubble on Tesla "magic".;)

Last night I charged... from my mother’s dryer outlet in the garage. I had to buy an adapter.

Oh... and I might have had a little too much fun on the twisty mountain back roads (see maximum G-forces display )

So does the vehicle, in this case the Taycan, know what you are plugged into, especially in homes, whether a 120v plug or a Dryer plug with 40 amps or 60 amps? how is this controlled so that the vehicle doesn't attempt to use too much amperage and trip breakers or cause potential fire hazard if someone has a too high amp breaker but a too thin gauge wire.? There must be some sort of control, either automatic or manual.

Wikipedia says:
A 1 kHz square wave at ±12 volts generated by the EVSE on the control pilot line to detect the presence of the vehicle, communicate the maximum allowable charging current, and control charging begin/end.[

+10000000 for what epirali said - the ONLY way a EVSE/Charger "knows" what a circuit can handle is via the kind of PLUG-Adapter the unit is currently using…

there is _NO METHOD_ to "check" what a circuit can handle - the Porsche Unit and Tesla unit "imply" the correct current (volts * amps) from the current adapter attached to the unit.

you should only be using the sorts of adapter that match the breaker and wiring for the plug you are plugged into.

this is what can happen if you try and pull 40/50 amps across a 30 amp circuit - good thing the metal box stopped the fire

yes. I believe the Porsche Mobile Connect does analyze the line.
