6 FAQs about [Battery series short-circuit current increases]

Does adding batteries in series change short circuit current?

In this case adding any number of batteries in series won't change the short circuit current, but putting then in parallel multiplies the current by the number of batteries. From your measurements, I think what is going on is close to case 1, not case 2.

Does putting a battery in series increase open-circuit voltage?

If you model a battery as an ideal voltage source in series with a resistance, then putting batteries in series will increase the open-circuit voltage by n times the number of batteries in series, but the short-circuit current will not change because the internal resistance also increases by n times.

What happens when a battery short circuit is triggered?

When the external short circuit of the battery is triggered, the voltage and discharging current measured in the experiment change instantly.

What happens if a battery has a short-circuit current?

In normal conditions, the battery pack is connected in series with the same currents for each cell, resulting in equal changes in charge ( ∆Q ). However, if MSC occurs, the presence of short-circuit current causes the voltage to rise by the same value requiring more charge, i.e., ∆Q becomes larger.

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.

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.
