I am building a BMS system with 8 LTC6811 + 16 LTC3300-1 (i.e.96S) using active balancing similar to the reference design.
I am using LTC3300 boost+ method to distribute charge to the lower half of the upper stack for all but the upmost stack.
Now I am questioning myself what will happen if the highest stack has the highest SOC - do i have to add passive balancing for the upmost stack or switch a load to the stack to get rid of the excessive charge ?
Maybe this question is stupid but any advise welcome ;-)
Best Regards, Tom
