6 FAQs about [Imported battery internal short circuit test system]

What is the sampling rate for a short circuit test?

The destruction of the current path increases the short circuit resistance and the voltage is recovered, even though the nail remains in the cell. The voltage sampling rate at nail penetration and with the internal short circuit test is generally 1Hz; however, in this test, the sampling rate was set to 1kHz.

How do you measure a short circuit current in a battery?

The short circuit current was measured by connecting a 5mﾂｳ shunt resistor. In the model battery, a short circuit that triggers thermal runaway is observed; however, no actual thermal runaway occurs. Therefore, the trace of the short circuit remains and can be observed after the experiment.
