BQ34Z110- use with multiplexed battery packs

Hi team,

In one our applications, we need to gauge the capacity on multiple lead acid battery packs.

To do this, we plan to use a single bq device and sequentially connect the packs.

Will this topology be possible? Can this be implemented by changing only the "pack+" and "pack-" connections?

Regards,

Hi team,

Can you please help with the below information.

We need to close on the design topology.

Appreciate an early reply!

Gitesh,

You will need to connect the cells to the Bat+/Bat- terminals. The device will run an FCC simulation and estimate the capacity after it is attached to the cell. The accuracy will depend on how closely the your cell matches the ChemID. You should run an optimization cycle to calibrate QMax and the Ra-table to your cells.
