What BMS_a035 means

BMS_a035 means Tesla has temporarily reduced your maximum charge level to protect the battery. This is the protection system working correctly. Usually resolves within a few days of normal driving.

What to do

✓ This is battery protection working correctly. Usually resolves in a few days of Level 2 charging.

Switch to Level 2 charging — Give battery a break from DC fast charging for a few days.

Park in cool conditions — Lower ambient temperatures help the battery recover faster.

Do not force higher charge limit — The BMS will restore your limit automatically. Do not try to override it.

Monitor over 3-5 days — If limit does not return to normal within a week contact Tesla Service.
