primary multi cell batteries LiMnO2 fuel gauge

Bruno,

You could use a CEDV gauge such as the bq2052. The discharge curve is not as flat as some primary chemistry's, so the bq34z100 (IT gauge) may work for this cell. It would be our best choice for an IT gauge.

Thanks, 

I have the bq34z100EVM Eval.kit with the EV2300. 

I started the Eval. SW: bq34z100 Evaluation Software (Rev. A)

How can I simply initialize the Pack Capacity of my primary cells (LiMnO2) which is 12Ah.

I tried to set in the DataRAM the Full Charge Capacity and the Remaining Capacity, but I couldn’t change it to my primary battery pack data.

Can you indicate how to do this, step by step? Thanks

Bruno,

You can following the Design Steps guidelines in the bq34z100 datasheet. (pg 28) You will set the Design Capacity and QMAX for your cells during this process. FCC and RM are simulation values that are leveraged from the Design Capacity and QMAX.

Tom
