State of Health, State of Charge, and Internal Resistance:
● SOH: The state of health shows the difference between
the battery being tested and a new battery, considering
cell aging. The SOH is defined according to the
maximum battery charge ratio and its capacity.
● SOC: The state of charge describes the difference
between a fully charged battery and the same battery
in use. It analyses the remaining quantity of electricity
available in the cell. The SOC is established according
to the battery's remaining charge ratio, divided by the
maximum charge that the battery can deliver.
