Tesla BMS a079 Symptoms: 5-Week Results (Avoiding the Error as Much as Possible)
This experiment is based on a user scenario in which a vehicle that is already out of warranty shows BMS a079 symptoms, and the owner tries to continue using the car as stably as possible while accepting a certain level of inconvenience.
It has now been five weeks since the BMS a079 phenomenon was first detected. So far, the BMS a079 error code has still never appeared. At around week 3, the battery condition worsened slightly. So, we limited the charging level to 60% and capped the maximum cell voltage at around 4.0 V. After applying this adjustment, both week 4 and week 5 have shown similar and relatively stable behavior.
As a result, the vehicle has been used for about five weeks without triggering the error, and we plan to continue the experiment in the same way going forward.
