Hello Ti Expert:
Our current 4S1P battery uses BQ40Z50-R4, when the battery level is 0%, it is activated after shutdown, and then charged with 14V&2.5A, and it takes 18…
Hi Nick,
Yes, you are right! If the voltage detect circuit has false soldering, it might be effect the FCC update incorrect.
During weekend, we did such test: we disconnect the voltage detect cable for cell 2. In two days, there many times FCC update…
Part Number: BQ34Z100-G1 Other Parts Discussed in Thread: BQSTUDIO , Tool/software: Hello,
We seem to be noticing abnormal SoC jumps on our batteries, especially when it's left idle. The SoC jump is inconsistent and not always repeatable , which makes…
Hi,
thank you for you answer. For the voltage calibration used the bqCONFIG a voltage between 3,7V and 4,0V. My Cell allow the Voltage 4,2. I'll try it again...

This value is to High. Our…
Hello Wyatt,
Before I talk about the logs, let me tell you about a mistake we had made in the pcb design. We have skipped the "Kelvin Connection" that was told in the datasheet. This is newly noticed. To fix it in the best way possible, we have soldered…
Part Number: BQ28Z610-R1 Other Parts Discussed in Thread: GPCRB Tool/software: We have a project, after low temperature compensation, when verifying the accuracy of low temperature SOC, it is found that FCC will not be updated when the temperature changes…
