Other Parts Discussed in Thread: BQ28Z610-R1, BQSTUDIO, BQ28Z610, GPCCHEM, BQ34Z100-G1

Hi Team,

My customer uses ICR18650-26J battery for their application.
I heard the application is rarely discharged.
Could you tell me which TI gas gauge (system side) is appropriate for 1 cell and 2 cell series application each?

Hi Nick-san,

Thank you for your support.

1) Is there chemID for ICR18650-26J?
2) I found bq28z610 in bqstudio however couldn't find bq28z610-r1. Is it common for bq28z610-r1?

Hi Yaita,

We have not characterized this exact cell but there is likely a match using GPCCHEM
You can download the bq28z610-r1 .bqz for bqstudio here: https://www.ti.com/lit/zip/sluc653

Hi Jayden-san,

Thank you for your kind support.
I understand bq28z610-r1 should be a pack side gauge.

If so, I would like to ask the following inquiry.
This is the first question on this thread.

I haven't received a reply yet.
Is it a difficult question? I just want to suggest TI gauge to my customer..

I chose the following system side gas gauge.
Are these reasonable devices?

Hi,

For 1s application, BQ27520 is suggested.

The bq34z100-G1 would be your best option for a system side gauge supporting 2s.
