How-To Calculate the Prospective Short-Circuit Current or

A PSC tester first measures the open-circuit voltage at the terminals (V S, see Figure 2). Then it applies a small load for a short time to make a current of a known value flow through the circuit (I T, Figure 3). With the test current flowing, the instrument again measures the voltage V at the terminals.

6 FAQs about [How to test the battery short circuit current]

How do you calculate short circuit current in a battery?

The short circuit current of a battery can be estimated using Ohm’s Law, which states that Current (I) equals Voltage (V) divided by Resistance (R). In the case of a short circuit, the resistance is extremely low, nearly zero. So, the formula simplifies to: Short Circuit Current (I) ≈ Voltage (V) / 0

What is a battery short circuit?

A battery short circuit occurs when there is a low-resistance or no-resistance path between the battery’s positive and negative terminals, leading to excessive current flow. The short circuit current in a battery can vary widely depending on the battery type, capacity, and internal resistance. It can range from tens to hundreds of amperes.

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.
