The instantaneous short circuit current is determined by the setting of the output voltage divided by the resistance that is in series with the discharge path. The amount of time this discharge event is present (and its rate of decay) is determined by the amount of capacitance and resistance present in the discharged circuit.
The internal resistance may be used to calculate the theoretical short circuit current but the method used is open to debate. Never the less, values of the internal resistance may be used to estimate the actual short circuit current in a battery system.
Sustained current is the fault current that will flow in the circuit if it is allowed to persist after the transient process end. I fp is the first peak short circuit current. It is the maximum instantaneous value of the current that will reach during the first moment of a short circuit current.
In summary, the instantaneous short circuit current is a pulse of current that discharges the capacitance of the supply, and the continuous short circuit current is the current limit level set and controlled by the current mode of the power supply.
Short circuiting a battery means excessive current follows an unintended path, due to an abnormal connection with little or no impedance. This condition allows an excessively high current to flow with little resistance. An uncontrolled surge of energy can damage the circuit, and result in overheating, skin burns, fire, and even explosion.
For large batteries such as those used in Power Stations, short circuit currents may exceed 40k amperes. Even when the battery is not fully charged, the short circuit current is very similar to the published value because the internal resistance does not vary substantially until the cell approaches fully discharged.
