Part Number: BQ27426 Other Parts Discussed in Thread: GPCCHEM Tool/software: Hi，
The discharge will suddenly drop from 70% to 50%. What is the reason for this?
Currently, the TI database uses the chemical ID 5377. Could you please check if this ID is…
Hi Aldrina,
For clarification, when you say that the correct chemID has been configured, do you mean one of the three preprogrammed chemIDs for bq27426?
Can you please tell me how large is the seen offset for the voltage?

Part Number: BQ27426 Tool/software: Dear TI Team,
When we used BQ27426 for battery power measurement, we found that the voltage read was only a few mv different from the one measured by our multimeter, but the measured battery capacity was quite different…

Hello Sir
If we use bq27426 with cell voltage is 4.45V, is this doable? what chem IC we could use?
Part Number: BQ27426 Hi team,
I am working on BQ27426 fuel gauge EVM. I wanted to know the steps that I need to follow to change the chemID from 3230 to chemID 7365, which is the CNTL_DATA value to change the chemID to this particular value.
Thanks

My customer use BQ27426 in handheld device.
When he reads the SOC using the I2C command, it has a 50 percent chance of reading the number 0. Our SCL frequency…
Part Number: BQ27426 Tool/software: In our design, the fuel gauge is always on because it is connected to the battery, pull-up resistors (4k7 ohm) are disabled until the microcontroller launches a measure, so i2c lines are floating we don't use a 1Mohm…
Part Number: BQ27426 Hi Team,
I am working on BQ27426 fuel Guage. The learning cycle has been completed and I have got the golden learning images in .fs file format. I am new to working in TI based fuel gauges. I wanted to know the steps that I should…
Hello Dominik，
Back to the problem at the beginning:
Inserting a battery with SOH=73%, loading the Fs file (reserve capacity 350mAh), and again failing to learn successfully via Golden learning.
Is it possible to make Fuelgauge learn the FCC of a battery…
