Whats Does SoH and SoC do In a Battery Management System in EV
In EV Battery Management System, what's the purpose of the State of Health and Charge (SoH, SoC). And how are they measured. Is the strength and capacity of the System dependent on these factors and what could occur if the system lacks SoH and SoC.

Very interesting topic. SoC/SoH can not be measured rather always estimated.
Simply said, SoC is how much juice is left out in the cell if considered as a glass (the range on your EV dashboard) and SoH is what's the size of the glass(hypothetically think that this keeps shrinking)
The accurate estimation of this is still a challenge and people do it with 2% to 5% tolerance easily.
ok 2 to 5 tolerance is not that bad, thanks
