What are your highest charging amounts? (Hall of Energy)

[rs38]

- started with 29°C, 1% SoC to 100% and battery saving mode
- Car is 37 months old, 38.000km, SoH of 89%
- though not necessary it started to cool down the battery back to 30°C, wasting ~1kWh
- there are no AC charging losses included, but cooling.

I think it can be quite interesting to estimate real world SoH from these kind of data.

I'd like to collect some data from you, ?

Are you asking for feedback on how much energy can be charged into the Taycan from a low charge level to 100%?? And that displayed from the screen of say an Ionity station?

Surely that also takes into account the losses in the station itself in converting from AC to DC? I thought we payed for the electricity used at the station?

But I am certainly willing to try at some point to bring some data.

no need for the pictures, only SoC delta, time and DC energy charged. start and end temp would also be nice and make it more accurate.

For DC you only see (and pay) the energy without AC converting losses. Therefore it should be more precise.

some data from recent trips

My highest charge amount was 100% but only tried it a few times by accident. Lowest was 0%. Somehow, the car still works after the abuse.

That is some interesting data. How did you acquire the data? I can understand the charger information. But how did you see the average kW ans start and end kWh?

from Car Scanner, the Battery Energy parameter.
It seems to be a real one, I mean not computed from SoC*SoH.

wow!!

that's the perfect example I was looking for! what is your SoH?

btw: my Battery energy readings from Carscanner (there is no such reading in PIWIS btw) are very low and pessimistic and do not really match what I could actually charge and consume.

Interesting is that you show that there would be some losses when charging from Ionity, Fastned etc. But I guess that could reflect the consumption from the different ECU’s, water pumps, cooling units etc that are active during charging???

I also admire your diligence of recording all of this data. That is something I would not have the patience or discipline to perform.

 

[Gru]

I guess too… and you forgot to add the flashing purple light on the charger.
IMHO It’s not much compared to AC.

Actually I don’t keep records … it’s only after reading the thread that i thought to have a look at it : transferred CarScanner files to Excel, looked at My Porsche / Chargemap transactions record and extracted the numbers

I’ll check that tonight: between 89 and 90% i think.

They seem ok when comparing with data from the chargers, unless you mean there’s a delta starting from 0% ? Not sure how to verify this….

 

[rs38]

IMHO, the Battery energy readings from Carscanner do not make sense: see last 2 columns I added:

which SoC do you use? the "display" dash SoC or the "true" net SoC, that is not going below 5% and over 97/98%

for my statistics only the display SoCs make sense, but of course would not harm to know the real SoC as well

 

[Gru]

I used the High Resolution... but no clue if it's the good one or not.
why 3 different SoC ?

Correction: there are 6 different SoC ... Display in the car shows 50.

 

[rs38]

SoC true = gross (93,x kWh)
Soc Display = net (86,7 kWh real, 83 communicated)
only these 2 are of interest.
use net to compare against DC charging kWh

I took a snapshot earlier today: SoC true is almost identical to SoC Display ?
How is this possible ?
