Other Parts Discussed in Thread: BQ27Z561,

Hello team,

Why sometimes xCell0 R_a is different from Cell0 R_a? Is that normal? What cause it?

I did two low temp discharge test. The first test has same Ra , but the second has different Ra, as shown below.

Thanks,

Miranda

Hi Miranda

Can you attach your gg file? What gauge are you using? It appears you selected a wrong gauge for the question as the bq27z561 has only one pair of tables and not two as shown in your snippet above

thanks

I sent you the gg file offline.

Hi Miranda

Thanks for the files. You didn't explain that those are ra tables from two seperate gg files.

What you are seeing is perfectly normal. No cause for concern. The gauge updates uses one pair for calculations while it updates the other. So there will be instances where you see differences because of this. But that is perfectly ok.

thank

Onyx
