Yes you will need to set one for correct operation

Answer 2 · 2021-06-20T17:42:40.000Z

is it possible to find and load CHEM-ID without the EV2300/2400. It is not easily available in my country, and is ridiculously priced. Cant I use other I2C to USB converters like CP2112?

Yes you definitely can.
Find the chem id in the database and then follow the notes in the datasheet on how to edit the settings over i2c.
Sadly I cant help much more than this as I no longer own the EV2300 or dev boards.

Hi, where can I find the 'database' for CHEM-ID? I want to try with an 8S2P 32650 pack

Texas instruments manufacture the part and they provide the spreadsheet of id's

I got the chemID of a similar voltage and capacity cell. So if I feed that into the arduino code given, along with other parameters of the battery pack, I can get SOC data?

As per the instructions in the to docs, you need to give it a chemid of the closest match then perform calibration and training cycles (discharge and charge cycles) to allow it to calibrate
