Practical considerations such as the effects of temperature, state of charge and type of circuit protection device are also presented. battery’s short circuit current is typically estimated by dividing its open circuit voltage by its internal resistance.
Estimated short circuit values can vary widely depending upon the test method and measurement technique. Multi-stepped discharge test methods that use a large span in current and voltage provide the best accuracy in estimating battery short circuit current and resistance.
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.
Short circuit test of batteries is a bad idea because it can damage the batteries. Lithium polymer battery have a large discharge current on short circuit it may explode. You can discharge the battery using a proper dummy load for testing the capacity of the battery. Yes, I know.
Battery system circuit resistance, state of charge and temperature can reduce the nominal zero-voltage short circuit currents. Potentially dangerous short circuit conditions can be prevented with a better understanding of battery and circuit protection operation.
