Other Parts Discussed in Thread: BQSTUDIO
I am using BQ27Z561EVM-011, 1s6p battery cell, and 1.5A load.
1. I have triggered the learning cycle. At the stage of discharge, when I connect 1.5A load to BQ27z561EVM-011, my battery pack directly dropped 0.4V voltage.(3.37 V dropped to 2.98 V) So I can't able to complete the learning cycle. What is the reason behind that? I can negate +/- 25mV dropped but here more than 100 mv. When I have connected load directly to the battery it will dropped only 10mA. Is there any configuration needed in BQStudio?
2. Also, I have noticed that when I connect the battery pack to the BQ27z561EVM-011 kit and got 3638 mV voltage on BqStudio instead of 3370 mV (actual battery pack voltage). What is the reason behind that? I wasn't able to understand this behaviour.
