The newest version of the ABRP provides an indication of the the amount of kWh corresponding to the % charge required at each charging stop.

I have noticed that if you extrapolate the kW to 100% you get large variances in the the calculated total battery capacity.

For example, 3 stops, temperature more or less constant

29%->62% (25.8 kWh, @12C), 100% -> 78.18 kWh

21%->63% (34.1 kWh, @13C), 100% -> 81.1 kWh

18%->76% (46.8 kWh, @13C), 100% -> 80.69 kWh

Should this be the case?

As far as I understand about 84 kWh of the battery's full capacity of 90 kWh is made available.

The test was a 300 km roundrip made of 3 legs (each way) of motorway @130 km/h, country roads @95 Km/h speed with some 600 m elevation gain and a final mountain road at variable speed from 40 km/h to xxx km/h with another 1100 m elevation gain. Temperature from 29C (motorway) to 16C (mountain top), no air con. Started fully charged and got back home with 9% left.

Very little traffic in the motorway so the car was running @130 km/h as set in the cruise for 99,9% fo the time.

Useful data I can report are:

- using a value of 245 Wh/Km @110 Km/h in ABRP I get a consumption estimation very much in agreement with the real data (about 1% more) and over 300 km I think it'a pretty good result and confirms the genral experience of I Pace owners that reference consumption acutally proposed as default (271 Wh/Km @110 Km/h) quite excessive.

- average consumption of 262 Wh/Km @130 Km/h measured over a 52 km leg (50m elevation loss, so close to negligible).

If helful I can report exacly my trip but I don't know how to do it: save the tirip in ABRP and share it or just a screen shot?

]]>Probably the most promising solution is using the JLRpy tools (https://github.com/ardevd/jlrpy) to retrieve data from the car. There are probably limitations. If anyone's interested and knows a little Python (or is willing to learn), please give this a try and see how well it works.

Since neither of us (Bo or myself) have an I-Pace, developing this from scratch will be quite challenging. Without help, it will be quite some time before we can get a workable interface.
