Often, the peak short circuit current occurs within 5 to 15 milliseconds. Without some form of protection such as a fuse or breaker, a short circuit condition can cause permanent damage to
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.
Reliable battery supply short circuit current and resistance values are required in order to properly size and select the circuit protection device. Depending on the type of battery being used, different internal resistance and short circuit values exist.
The short circuit current is 4A. From the above discussion we can conclude that the current flowing at the time of short circuit is called short circuit current. To calculate the short circuit current we have different formulas based on the elements in the circuit.
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.
