BQ27510-G3 Default State

Other Parts Discussed in Thread: BQ27510-G3, BQSTUDIO

Hi TI Experts:

For the BQ27510-G3 fuel gauge, I understand that it need to configure the battery nominal capaity and other parameter.

 

What if I didn’t configure, it is fuel guage will able to detect my battery level in default condition??

I have try to connect Li-ion battery to bq27510-g3 directly using default condition and charging.

But the bettery level shown at bqstudio just remain.

Sometimes, the battery level dropped when the battery is still charging.

My Li-ion battery capacity is 1000mAh.

If we do not configure any parameter on the bq27510-g3, what reading that we suppose to obtain?

Please advice,

Wang

 

Please advice.

  • Hi Wang,

    Without programming the chem id for your battery and carrying out a learning cycle,your device will not be able to gauge appropriately. pls identify your chem id using the procedure listed in the link below for our tool gpc chem

    then carry out a learning cycle according to the attached app note:

    Once done, Extract a golden file which is what you will program on multiple chips. Your gauge should now be able to fucntion  properly.

    thanks
