Maximum battery charge current IBat,C,max and maximum battery discharge current IBat,D,max Maximum battery charge or discharge currents of the battery are the maximum charge or discharge currents, which are allowed only for a short period of time (e.g. some seconds) at the battery terminals because of heating reasons.
Presentation of a suitable definition for battery energy storage capacity and designation of state of energy (SOE). Definition of an appropriate reference (test) power value and explanation of the term ‘CP-rate’. Usable energy storage capacity value to describe limited usable energy content of a battery due to operational restrictions.
Maximum continuous battery charge and discharge currents are the maximum allowed charge and discharge currents of the battery, which the battery can consume and deliver continuously at certain conditions specified by manufacturer.
The capability of a battery is the rate at which it can release stored energy. As with capacity, the respective maximum is specified. The common unit of measurement is watts (W), again, with unit prefixes like kilo (1 kW = 1000 W) or mega (1 MW = 1,000,000 W). The C-rate indicates the time it takes to fully charge or discharge a battery.
The standard operating voltage of a battery is indicated by a reference value known as nominal voltage. It is a standardized measurement that illustrates the voltage range in which a battery typically functions.
Rated power capacity is the total possible instantaneous discharge capability (in kilowatts [kW] or megawatts [MW]) of the BESS, or the maximum rate of discharge that the BESS can achieve, starting from a fully charged state. Storage duration is the amount of time storage can discharge at its power capacity before depleting its energy capacity.

If we have an OCV of 3.7V @ 50% SOC and an internal resistance of 0.025Ω and we draw 10A from the cell the voltage will drop 0.25V This is simply Ohms Law. V = 3.7V – 10A x 0.025Ω = 3.45V. Hence the voltage of the cell under a 10A load will be 3.45V. We can also calculate the maximum current we can draw taking the cell down to the minimum ...
