Tool/software:
I’m working with the BQ769x2 family for battery management and I would like to implement host-controlled passive balancing, specifically for adjacent cells (e.g., Cell 15 and Cell 16) where both are imbalanced and need balancing simultaneously.
From the documentation, I understand the BQ769x2 handles balancing one cell at a time in autonomous mode to prevent thermal issues, but with host control, it should be possible to balance multiple cells — including adjacent ones — if proper timing is managed.
My questions are:
- Can the host enable balancing on adjacent cells (like Cell 15 and Cell 16) simultaneously via direct register writes, or will the device prevent this internally even in host control mode?
- If adjacent balancing is allowed in host control mode, are there any timing, thermal, or safety precautions the host must manage explicitly?
- Is there any reference timing or balancing algorithm available that shows how to manage multiple cell balancing via host?
