App charging data mismatch

[riverie]

After a charging session, the "last session" data in the app does not match the numbers for the same session in the "history" section. Am I missing something?

For example, my "last session" shows 46.6kWh...45.0 to the battery, 1.6 to "system".
The history tab for the same session shows 50kWh.

History is rounded up to an integer kWh, but looking at my app I see they match: Last session 83.5kWh (82.1 + 1.4), while history says 84kWh.

These numbers are from the vehicle end. If you compare them to the numbers recorded by your wall charger (if your charger supports that) you will see higher numbers because there is loss in the delivery of the energy to your vehicle. My wall charger reports 89.95kWh for that same session, and if I were paying for the charge at a public L2 charger I would be charged for 89.95kWh even though less energy made it into the vehicle.

I have a Rivian charger. I don't know if there is a way to get data from the charger, unless the "history" number comes from the charger.

Next time I use a public charger I will pay attention to the data.

The screen in the vehicle matches the "last session" number, not the "history" number.
