TI Team,

how to implement SOC and SOH logic for 100Amp. Please describe more effective words. please share some example of SOC and SOH logic.

Hi Furkan,

At such high currents and capacities you would be better served by using a monitor like the bq76940 that has protections available against failures unlike the bq34z100-g1. It also uses a much simpler coulomb counting algorithm that is less difficult to implement compared to the IT algorithm which needs more configuration and takes longer for production.

hi Batt,

I am confused in SOH logic. Can you explain and give some reference or example of SOH logic implementation.

Please clarify what you mean by SOH logic.

Hi Batt,

Actually i dont know how to implement SOH logic by gauge IC

Hi Furkan,

You don't need to implement any logic for SOH. The gauge learns it by itself and reports the values to you. Please read the TRM and other docs in the bq34z100 page if you want to understand the gauge performance. IT has many videos explaning it, you can find them here, and and also on youtube when you search for impedance track gauging
