Hello E2E Experts,
Good day.
I am using GPC to get chemID for a 2.7V Li titanate battery. The email never shows an error. I attached the GPC.zip file, and report, and an email screenshot. The GPC report is only a 0. What's the reason? Could you please help me?
Attached is the file.
Regards,
TICSC
I follow the Simple Guide.And I have modified my file several times, but it has begun to exhibit errors. Please tell me what I can do for this.
I plotted a graph using the data, as shown below. We are charging 20Ah with a small current of 2A. Could you please tell me why GPC keeps showing errors? Does this mean we cannot use this chip in our case? I look forward to your prompt reply. Thank you.
Hello,
The issue is with the data you have submitted. Your log data shows that there is no relax after charge and discharge.
Instead, your data should look like the following:

I don't think so. I changed the data, but the error still occurs, and my battery is 2.7V, while the report only lists batteries above 4V.
Or is there a laboratory in China where I can send the battery for testing?

Good day.
I replaced it with another set of test data from the same type of battery, and the result report still only shows “0”.
I hope you can give me some practical advice.I would greatly appreciate it if you could reply as soon as possible.
