bqWizard and bq78PL114S12: Idle TImer, Lifetime Delivered Amp Hours, Lifetime Maximum Power values not incrementing

John M

Other Parts Discussed in Thread: BQWIZARD

We're using bqWizard 2.5.18 and FW5000 in our bq78PL114S12's.

Is the Pack Dynamic tab's Idle Timer parameter functional? It's never gone past 0 seconds for us.

Is the Pack History tab's Lifetime Delivered Amp Hours parameter functional? Or does it only increment to 1Ah after 10Ah are passed since the current values are 0.1x with FW5000?

Is the Pack History tab's Lifetime Maximum Power parameter functional? It seems to change with the existing conditions instead of displaying the max power level the chip has seen.

Thanks!

Idle Timer is non-functional. I'll check on the others.

We've confirmed that the Pack History tab's Lifetime Delivered Amp Hours parameter is incremented at a 0.1x rate due to our using a 1mOhm sense resistor (Sense 1 and Sense 0 = High).

It seems that the Pack History tab's Lifetime Maximum Power parameter only gathers the current power level instead of the lifetime max when I Read All Parameters. I was wondering if you had a chance to confirm this?

Thanks!
