I am a problem in last calibration step.
Our design has 6 sets in series of 10 batteries in parallel. (60 in total) The batteries are common 18650 lithium ion cells. Thus we have 22.2Volts over the batteries.
Based on the default configuration of the BQ34Z100G1 we change:
- Pack Configuration: VOLSEL=1 (RED) so that it is D9D9
- CC Threshold: 20000mAh
- Design Capacity 20000mAh
- Gas Gauge: LoadMode = 1
- QmaxCell=22000
- Number of series cells= 6
- Design Energy =32000
- Design Energy Scale =15
When we calibrate the unit the voltage step responds with "Cell Voltage correction is beyond allowed range"?
Is there a setting that is not correct?
