BQ27421-G1: learning data

Part Number: BQ27421-G1

We have a question below.

We read and re-wrote learning data.

And then we compared the remained value of the battery before and after writing back,

they did't mach.

But,after 15hours we re-wrote the learning data,we checked the remained value of the battery before and after writing back.

Then,the remained value mached before and after writing back.

So,we'd like to know  wtat condittion  the remained value of the battery return the same value before we  re-wrote the learning data.

If leaving the battery as it is is a condition,we'd like to know the minimum time to leave the battery.

  • Hello Mitsuru,

    Can you share the data you're pulling from the gauge? What learning data are you uploading?

    The gauge will take an OCV after some time has passed and the battery voltage has settled, that will correlate to the SOC value.

    Sincerely,
