How do I fix Battery Brick Overvoltage on a Tesla?

Let the unit sit and self-balance, avoid forcing full charge. Then: Check for SOC imbalance alerts, then run a charge/discharge cycle and observe vitals.

Battery Brick Overvoltage

A brick group exceeded its voltage threshold, usually at top of charge or during imbalance.

Common causes

Cell imbalance at top of charge

What to check

STEP 1

Let the unit sit and self-balance, avoid forcing full charge.

STEP 2

Check for SOC imbalance alerts, then run a charge/discharge cycle and observe vitals.

Escalate if

Paired with hardware POD faults or repeated lockouts
