the fraction of the battery's capacity which is currently removed from the battery with regard to its (fully) charged state. For fully charged batteries, the depth of discharge is connected to the state of charge by the simple formula. D o D = 1 − S o C {\displaystyle \mathrm {DoD} =1-\mathrm {SoC} } The depth of discharge then is the ...
In practice, it depends on the capability of the charger. The battery capacity C is expressed in Ah units, typically the C 20 value based on a 20-hour discharge time. The charging current (in A units) can be written as C/t where t is a time. For example, for a battery with C = 40 Ah, a current C/10 is equal to 4 A. The charging current is a ...
