I found this discussion about Model S, which can read the battery's voltages and temperature from its different cells/modules using CANBUS.


Can Model 3 read the data from different cells/modules?
I need these data for battery health analysis.

Yes, the Model 3 reports individual voltage on each of its 96 cells across the CanBus.

I don't believe - I don't recollect seeing this, so could be wrong - it reports individual cell temps, though it reports minimum, maximum, and average of the population. (To be clear, it's possible the car is reporting individual cell temps, but that the developer of Scan My Tesla - the third-party app I use to monitor CanBus sensors - simply chose not to display them).

Correction, it only displays cell voltages.
