I wonder if the software update to restrict the maximum cell voltage by Tesla was actually even necessary...
In two years of ownership, I have probably only charged to 100% on two (or possibly three) occasions - and always on journeys when I actually needed the range. Therefore the cell voltages would have been reduced immediately after the charge finished by driving as I continued on my journey.
This implies that my charging behaviour was already in line with what Tesla has achieved with the software lock, and therefore that the cell capacity restriction is largely unnecessary... for my particular usage at least.
If it is in fact dangerous (cell fire due to dendrites) to charge to the full (4.2V ?) cell capacity, then that would seem to be a warranty issue which would require the pack to be replaced on safety grounds.
If I wanted a MS70 I would have bought one... but I did not because I wanted the range of the MS85 instead!
Does anyone know the cost of software unlocking a 75KWH pack to 90KWH? Because I estimate that this probably equates to the compensation amount owed by Tesla for capping my MS85 (was 77KWH) to the equivalent of a Model S70 (now 68KWH)
I am in a similar boat. In 3 years I:
Charged up to 100% less than 10 times, every year annually to check and record the range, for degradation and comparison purposes, otherwise it was for an immediate journey.
I only Supercharged about 10-15% of the time.
I normally operated between 20-80%
I never kept the car for any length of time at a high SoC. After logging the annual 100% range figures I always drove it to reduce the SoC.
But my battery has been capped by just over 15%.
So logic suggests that Tesla's actions don’t seem to be linked directly to how we have treated our batteries. I assume they must have found, or mis-diagnosed Plating, but given how carefully I have treated my battery over the 3 years, it seems unlikely. So, as today is learning day, I am open to suggestions.
I also don’t really want money, I would just like my battery back to where it was. In response to Tesla's claim that I should wait patiently as they 'are working on a solution' I did suggest if they were that confident they could give me a loaner until the solution was found, or a temporary battery until the solution was found, or compensation, each week, until the solution was found. They haven’t responded yet.
