A short circuit causes the resistance of the whole circuit to be dominated by the internal resistance of the battery. Consequently, the current in the circuit is of the order of the emf of the battery divided by the internal resistance, which can be very high if the internal resistance is very low.
A short circuit in a battery is the formation of a low resistance path between the terminals. This results in the battery's internal resistance dominating the circuit's overall resistance.
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.
The consequences of a short circuit can vary widely. A short circuit can result in a violent event if the amount of current available from the battery to flow through the short circuit is extremely high (as in the case of a car battery). Conversely, it can be a non-event for a low capacity battery, such as short circuiting a AAA alkaline battery. Hope this helps. Exactly.
Accurate battery system short circuit current and resistance values are required to properly size and select the proper circuit protection device. Estimated short circuit values can vary widely depending upon the test method and measurement technique.
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.
