Hello Alec,

Let us take a look at your data and get back to you shortly.

Sincerely,

Hi,

Which part number is this for.

Thanks,

Hi Nick,

bq4050

www.ti.com/.../sluub45b.pdf

Hi Nick,

1. Chemistry is LCO, Graphite. High current charge design, low internal resistance

2. Do you think the error data is temperature behavior? 

    if yes, I put battery in Notebook computer and run a light load app @room temperature

    the temperature behavior is very similar to CEDV log. discharge current around 400mA and Battery is 4000mAh 3S1P

If the error is not temperature, I can't figure out the problem, so ask for help here

I do follow the procedure of sluub45b 

Another question: 

If smoothing config [SMEN] is set 0, Can I disable the correction of EDV1  (3%)

Sincerely,

Hi Nick,

Thanks

Can you tell me how to disable EDV1 correction of bq4050?

Hi Nick,

Is there any information for me?
