Hello,
We are using BQ27531-G1 on a PCB that is used to analyse the batteries. After charging and discharging, the test result is shaped by the voltage interval of the batteries. If they are in a range which is determined by us, they pass.
Sometimes the batteries fail on the real device in different aspects and in order to eliminate these already failed batteries before using on the device, we want to increase the capability of our PCB by enhancing our data variety that can be taken from the Gauge IC.
In this regard, what parameters could you suggest us to take from the BQ27531-G1 to eliminate the batteries that are operate unnormal? I think because it is an analog measurement, voltage values are more reliable than the SoC values. Therefore, we are using a voltage measurement range as a test parameter.
Can we get "internal resistance" (DC) of the batteries (I couldn't find something like that on the datasheet), or something that could help us sort out? Thanks in advance.
Best Regards,
Caner
