Battery Internal Resistance & Short Circuit Current.
It therefore follows that the subject of battery short circuit current can have at least two points of view when looked at in practical terms. 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 ...
Research progress in fault detection of battery systems: A review
Compared with the electrochemical model, the precision of the equivalent circuit model is slightly reduced, but the modeling difficulty is also reduced to a considerable extent. As illustrated in Fig. 4 (a), the essence of the method is to use resistors and capacitors to form a lumped component circuit to equivalent various operating modes of the battery.

Protection schemes for a battery energy storage system based …
The post fault quantities can be obtained by adding the prefault quantities with these changes referred to as superimposed or fault imposed quantities (3) V p o s t = V p r e + Δ V (4) I p o s t = I p r e + Δ I Superimposed impedance can be defined as (5) Δ Z …
For example, if the maximum single-phase fault current measurement is 4.6 kA, then the maximum value of fault current between line conductors is calculated as: 4.6 kA x 2 = 9.2 kA. The connection of a three lead instrument to measure single-phase earth fault current is shown in Fig 2, the test is repeated for each line.
