LG Chem cells in EU TM3 LR detection

[filipkroca]

Additional context There is a big discussion about Chinese LG Chem NMC811 cells used in some EU cars build in Fremont (code E5D) - 77 kWh battery pack. discussion on Teslamotorsclub DE discussion on ttf-forum

It is very common to measure the degradation and charging performance of these new cells supplied to consumers without their knowledge. We should have a comparison to Panasonic NCA because right now these cells have about 50% slower charging performance.

It looks, that Tesla is now supplying EU TM3LR 2021 randomly (without noticing) with 3 battery packs: E3D = 79 kWh (old Panasonic NCA) E5D = 77 kWh (Chinese LG Chem NMC811) E3D = 82 kWh (new Panasonic NCA)

Describe the solution you'd like All three types have the same rated constant, it will be challenging to distinguish these packs in used cars. I think, that we should notice these owners and manually select the battery pack type according to car documents and have very precise statistics.

This would be really helpful, since charging performance of E5D is far inferior to E3D and the statistic on "fleet max charging" for the "MR LR FL" is completely useless, due to the different battery packs.

As far as I know there is not possible to distinguish between these packs on API Side.
