BQ25622: Determining battery State of Charge from observable parameters

Nandor Janky

Part Number: BQ25622

Tool/software:

Hey,

Can you please advise with an algorithm/formula/application note on how to determine the managed battery state of charged based on the BQ25622 state and ADC measurements during charging and discharging?

I'd really not like to add an additional battery gauge IC if this is doable with only the BQ25622 IC.

Thanks & BR,

Nandor

Nandor,

Please refer to https://www.ti.com/lit/an/sluaaa1/sluaaa1.pdf The application note uses BQ2515x as example. If further support is needed, please submit a new e2e thread for BQ2515x and the appropriate team will help.

Thanks,

Ning.
