As stated elsewhere I have had a main traction battery failure and got two modules replaced. Now that the car is back and I have looked back at some statistics from the car, I found some interesting but also concerning issues with consumption reporting.
As we all know the consumption from a trip is reported in MyPorsche app and website. On the last days prior to my battery failure I looked at the data that the car has reported in the app. From there everything looked absolutely perfect.
Date. Distance driven. Cons My Porsche Tronity app
30.8.23. 116 km. 19.8 kWh/100 km. 21.8 kWh/100 km
30.8.23. 115 km 22.5 kWh/100 km 31.0 kWh/100 km
03.09.23. 145 km. 19.3 kWh/100 km 38.9 kWh/100 km
So huge difference?? I have assumed that Porsche measures the energy taken by the drive train, while Tronity looks at the overall SoC at beginning and end, and the calculates the energy consumed ( or needed to be replaced to get back to SoC?).
Looks like the Tronity app would have indicated a problem much earlier!!
I have looked at a few earlier samples on long distance driving and then the difference has been small about 1 kWh/100 km. But still a difference. Distance driven in these cases were 250 km.
Are there any other Tronity users in the Forum that could check their comparisons??
