Hello. Tesla S 2013 (US). The problem is that when charging DC connections up to 50 kW via Chademo, after 10 or 20 minutes the charging disconnects and throws errors BMS_w035, BMS_w151, GTW_018. The car does not run and the 12V error GTW_w174 occurs. However, after some time the system recovered and I was able to drive. The error disappeared, only indicating that the 12V was weak. As it is now winter and cold, I had the impression that the system had disconnected during charging because some element had heated up, which cooled down after some time, and the system resumed after checking. After repeated DC charging and disconnection. I decided to charge with the AC connector. Charging almost succeeded to 80% and disconnected again with the same errors.
The service suggested me to replace the HV battery heater or the charging plate (I have two of them it seems). However, I have the impression that the 12V battery is to blame. Because the AC charging took 4 hours but the 12V has not recovered and is currently dead. I think the weather may have rusted the terminals or something, or the lifetime has expired and shortening is in progress. Could it be the wrong 12V causing AC or DC charging to stop?
