244 Mile Round Trip Took 84% SoC

[Jhenson29]

The longest trip I ever need the Taycan for (and I knew this when I bought it) is 244 miles round trip. My goal was to be able to do this without public charging.

Seemed reasonable.

Today, after over 13 months and over 13k miles, I finally had to make the trip.

And the Taycan did beautifully.

I started with 100% SoC and ended with 16%.

Piece of cake. The Taycan has completed all of its required tasks (for me) with no need for public charging. Success!

It may not make in winter though.

The only thing I can’t figure is…

It took 40% SoC to go out (100-60) @ 27.8kW/100mi and 44% to come back (60-16) @ 26.9kW/100mi. Seems like there’s some missing information somewhere.

Any elevation gain? What about wind? That will explain the slight variance.

I would expect either of those to be reflected in the consumption rate.

My issues is, why would the same distance at a lower consumption rate use more battery percent?

I can only assume there is other missing information, or possible the better measurement can just be that far off.

Guess-o-meter variations between the time during going out and back? That is, the algorithm changed its assumptions and calculations WHILE you were doing the drive based on your driving during the out portion?
Just a thought.

Displayed SoC is live.

Average consumption is calculated looking back, not forward.

Not much to guess at, depending on how accurate the car actually knows SoC.

Anyway, the main point was just to highlight the range of the car.

There are already lots of other examples. I was just adding to to it.

That’s great range. Which drive mode are you mainly driving the car in? What type of wheels do you have?
I still haven’t been able to get mine above 240 mi on a full charge.

I have 20” sport aero with all season tires.

I was in range mode for this trip (first time I used it other than just testing), but I normally drive in sport while my wife normally drives in normal.

We had the AC in eco (not plus), with my side set to 74 and her side set to 77 with an ambient outside temperature of 90.

Not much to guess at, depending on how accurate the car actually knows SoC.

I have noticed that sometimes the SOC is not super accurate. Here are the dash readings recorded on two minute intervals from a trip last year. Air temps were around 70F and speed was 71.5 mph (cruise control). Ultimate distance travelled was 300.8 miles. Winds were calm.

Elapsed Time in Minutes	Speed mph	SOC %	Distance Traveled in miles	Elevation in feet
0	0	100	0	551.2
2	0	100	.6	570.9
4	62.2	100	.6	582.3
6	71.5	100	3.1	582.3
8	71.5	100	5.6	649.6
10	71.5	100	7.5	584.0
12	71.5	98	9.9	544.6
14	71.5	97	12.4	462.6

It took the SOC more than 10 minutes to reflect any energy consumption even though the distance traveled was 7.5 miles near highway speeds and a little uphill. After this the SOC declined about 1%+- for every two minutes throughout the trip.

There appears to be some fuzz in the PCM reported numbers.

It could be AC usage

@Jhenson29 What was the source/app for the trip data images you posted?

Connect. it’s the old app before the newer my Porsche release. I still like it better, not least because it has a widget like this:

Interesting. I wonder if battery charge level reporting is non-linear, whether by design or by nature? Maybe the hidden buffer skews it / or they’ve mapped a charge reporting curve to allow more granularity in the lower X%.
