Using BQ34Z100-G1 with NiMH, which chemistry to select ?

Other Parts Discussed in Thread: BQ34Z100-G1

Hello. I am hoping to use the BQ34Z100-G1 with a 10S stack of NiMH cells, capacity is 10,000mAh. The exact cell model is not offered on the Chemistry page of Battery Management Studio so I have selected 6103 and set all other registers to suit the pack. Is this sufficient, or do I need to model the pack more precisely ?

Thanks

Richard,

You should check to see which ChemID is the best match to your cell and it may even be necessary to characterize your cell. I can check for a match using a Mathcad program. You can use the attached document for guidance in collecting the data.

Thanks Tom

I note that it is also possible to submit cell samples to TI for characterization. Could you give me further information on this service ? I am located in the UK but could ship worldwide as necessary. Thanks again.
