Sir,
We are using EVM of bq78PL114 with 8 Cells in series of LiFePO4 which have 10Ah/cell. So at the begining we choose Chemistry file ID 410 which is likely most with our batteries(10Ah). We wonder about initial inputs for gas gauging as mention in bq78PL114 and bq78PL114S12 Technical
Reference Manual --->http://focus.ti.com/lit/ug/sluu330b/sluu330b.pdf on pang 50 , 8.3.1 OCV.
- Does it necessary to choose the right Chemistry ID file at the first time? If yes, what should we do if we don't have any information about batteries(from end customer)?
- We have changed another CHEM ID (10 Ah and the same type) but there's nothing different with Full Charge Capacity.
Best Reagrds,
