BQ34Z100 OCV Table

Hello!

I currently work with the BQ34Z100EVM and the EV2400. I tried to achieve a succesful learning cycle for this board. It seemed to have worked well since the Ra Tables and Qmax were updated and Update Status has the value of 0x02. But I still have no value for the OCVa Table. Shouldn't this also be updated during the learning cycle or is there another way to set the desired value for the entry in the data flash?

Patrick,

The gas gauge device never updates the OCV table and the table contents are not displayed in the data flash section of the bqEVSW tool. Your setup should be okay as long as the proper ChemID is shown. You can change the ChemID using the bqChem tab.

Tom,

Thanks for the reply. Is it also possible to program OCV-SoC Tables to the gauge for Cells that aren't listed in the bqChem tool?

The device only works with OCV tables from our ChemID's. We can characterize your cell and create a ChemID, if it is not in our portfolio.
