BQ40Z50-R1: bq40z50-r1 : normal value of MaxError() ?

Peter,

Part Number: BQ40Z50-R1

Hi,

I am reading p.113 of sluubc1d.pdf.
I would like to ask about MaxError ().
When operating with general charge / discharge, what is the normal value of MaxError ()? 1%?

Hi,
If the Qmax and Ra Table have been updated and operating normally, the MaxError() will stay at 1%.

dear Batt, Swami,

I understand.
If you are using bq 40 z 50 - r 1 normally, both QMax and RaTable will be updated, right?

Example of "normal use":
full charge,
full discharge,
more than 90% charge,
less than 10% discharge,
10degC <= temperature <= 45degC

Yes, once you learn capacity and resistance the error will be set to 1%. For every cycle that it doesn't learn, the error progressively increases.
