Hi,
We are currently studying fuel gauge solution suitable for important range (10Ah to 110Ah voltage 10V to 30V) of Li-Ion and lead acid battery et are very interested in BQ34Z100-G1 solution.
I read lot of forum discussions, AN and datasheet but i didn't find any information about reliability of SOC in case we don't charge 100% the battery during long period, for example 3 months (our system will be connected to solar panel 300Wc and during winter, we won't be able to charge 100%).
Could you please give me information about reliability of predicted SOC in that case.
Moroever, is there any restriction in our use case please?
Typical profile of utilisation:
Max charge current: 12A
Max discharge current: 5A
Discharge cycle: 10% to 30% of full capacity each night then charge during the day (for battery 10Ah, max charge current 1.7A and for battery 110Ah, max charge current 12A)
Other point, due to offset input of 10µV, in case of 1mOhms resistor for 110Ah battery, i understand that i won't be able to have precision more than 10mA, is my understanding correct please?
Many thanks
Best Regards,
