6 FAQs about [Battery short circuit current measurement]

How do you calculate a battery's short circuit current?

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.

Can internal resistance be used to calculate short circuit current?

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.

How accurate are battery short circuit values?

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.

What is a good short circuit current for a battery?

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.

What is the short circuit current of a 2500 Ah battery?

In comparison, the published short circuit current for a single cell is 6,150A. Consider a 2500 Ah cell having a published internal resistance of 0.049mΩ. This battery has 240 cells and the external circuit has a resistance if 21mΩ. The short circuit current is estimated to be:-

What is the short-circuit resistance of a battery?

The short-circuit resistance of a normal battery is a constant value larger than 42 kΩ that does not fluctuate with pressure. In comparison, the short-circuit resistance of an internal short-circuit battery is 4.2 kΩ at 0 kPa. The short-circuit resistance drops to 0.9 kΩ as the pressure rises to 120 kPa.
