Week 8 Update After Tesla BMS a079 Symptoms (Trying to Avoid the Error Code as Much as Possible)

This experiment is based on a user scenario involving a vehicle that is already out of warranty and has shown signs of the BMS a079 symptom. The approach focuses on keeping the vehicle operating as stably as possible for as long as possible, while accepting a certain level of inconvenience.

It has now been eight weeks since the BMS a079 symptom was first detected. So far, the BMS a079 error code has not occurred even once. Around the third week, the battery condition showed signs of further degradation. From that point on, the charging limit was adjusted to 60% state of charge, with the maximum cell voltage limited to approximately 4.0 V. After making these adjustments, the battery condition has remained relatively stable at a similar level.
