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

Are internal short circuit faults a threat to Bess safety?

Among these faults, the internal short circuit (ISC) faults pose a significant threat to the safety of BESSs. Relevant studies focus on ISC fault diagnosis itself and ignore the impact of battery aging within the pack on fault diagnosis.

How do you detect a short circuit in a battery?

Thermal detection: determine whether a short circuit has occurred by attaching a thermocouple to the battery side wall to detect temperature changes. Since the heat is conducted from the inside out when the short circuit occurs, the temperature shows that there is a certain lag, so that the short circuit situation cannot be fed back immediately.

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.

What is a forced internal short circuit?

Forced internal short circuit is mainly to add metal embedded parts and diaphragm puncture holes inside the battery and then combine the form of external extrusion to achieve internal short circuits in different parts of the battery.

Can cell swelling information be used to detect an internal short circuit?

What is the difference between a cell voltage and a short circuit current?

The product of the cell voltage (V) and the short circuit current (I), VI, is the heat quantity generated at the short circuit point, while the product of the di・erence between the open circuit voltage E and the cell voltage V and the short circuit current, (E-V)I, results in temperature elevation of the entire cell.
