Part Number: BQ34Z100-R2
Tool/software:
Hello,
Description of the problem:
I'm trying to correctly set up the parameters in the BQ memory. I have many doubts whether the values I'm entering are correct, so I would appreciate verification and possible correction.
I performed the calibration. I chose the Chem ID based on what I think is correct. Soon, I will carry out the test necessary to determine the Chem ID using GPCCHEM. Before starting the learning cycle, I would like to verify whether the parameters I entered are correct and if the number of modified parameters is sufficient. Maybe I missed something. According to the SLUA903 document, the amount of provided data seems to be fine.
Data:
Lead Acid Battery: 12V 72Ah,
Design Voltage: 2100 mV [12.6V/6], I'm wondering if the value should be 12V.
Design Capacity: 7200 mAh [72 000mAh/10],
Design Energy: 15 120 cWh [72 000 mAh * 2.1V)/10], I'm wondering if the value should be (72 000 mAh x 12V) / 40 = 21 600 cWh.
