BQ20Z45 Update Status 2S1P

Mike_chute

I have 5 cycles on my engineering pack and I there is a 0D in the Update Status. What does that mean? I have 3% max error but the Cell0 and Cell1 Ra_flag is at FF55.

That means learning wasn't completely successful. That happens if an Ra update occurs before a Qmax update occurs. To fix this and get Update Status to 0E, you will need to do another charge, rest, discharge cycle.

Hi Chase,

I've done the learning cycle twice and still have the 0D as Update Status. If I'm not mistaken this means that Ra tables wasn't updated.

My discharge current is about C/4.4, somewhere in this forum I read that for correct Ra update, discharge current need to be C/10.

Is this correct?

Hi Alex.

You need discharge rate to be between c/5 and c//10 in order to have a successful learning cycle.

thanks
