AI Customer ServiceThe battery internal short circuit data set is generated through the simulation of the internal battery short circuit mechanism model. And the classification level of the severity of the internal short circuit of the battery is defined.
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.
Temperature distribution of the battery in case of internal short circuit. The external characteristics of the battery when an internal short circuit occurs are mainly manifested in the abnormal response of parameters such as battery voltage, current, capacity, SOC and temperature.
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.
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:-
