Other Parts Discussed in Thread: BQ34Z100,
BQ34Z100 / BQ78350R1-A
We are considering the ICs bq34z100 / bq78350R1-A for battery gauging (State of Charge and State of Health) and would like to clarify the following points:-
1) Our batteries will be having a max capacity of 200AH with max discharge and charge currents as 200A and 80A respectively. Would the above ICs be suitable for the given specifications?
2) As per the datasheet, the BQ78350-R1A when used standalone would determine the SOC using a CEDV algorithm and not a coulomb counting algorithm. Could you comment on how accurate the CEDV algorithm is in comparison with the coulomb counting algorithm?
3) Does the BQ78350-R1A require its companion front end for operation or can it be used with other front end such as the BQ7791506 (or other protection IC)?
I believe it needs communication from the front end which is not available in the BQ7791506
Are there any other parts available for battery gauging as per our specifications above?
Post clarification of these doubts, we can discuss the way forward
Let me know if you need any further details. Looking forward to hearing from you.
