Currently, a huge study has focused on the single battery’s short circuit. However, cells are often interconnected into a module in real applications. There are many possibilities that external short circuit of a single cell has huge impact on the other cells in a battery module.
ACTUAL SHORT CIRCUIT CURRENTS FOR VRLA BATTERIES “shorted” lead acid battery has the capability of delivering an extremely high current, 100 to 1000 times the typical discharge current used in most applications. Electrical systems using batteries must be properly protected to avoid potentially dangerous fault conditions.
battery’s short circuit current is typically estimated by dividing its open circuit voltage by its internal resistance.
Chen et al. found that the higher the state of charge (SOC) during a short circuit leads the battery to heat up more quickly and inflict more damage, and a lower SOC lowers the short circuit current and lessens damage while releasing more short circuit capacity . Kriston et al. divided the battery short-circuit current into 3 stages.
Shriram et al. performed a systematic study of the internal short circuit mechanism inside a lithium-ion battery . They found short circuit between lithiated anode material and aluminum current collector, resulting in maximum heat generation.
However, the short circuit fault, a common fault that results in battery accidents, can be caused by vehicle collisions, line aging and maloperation. Short circuits can be divided into internal short circuit (ISC) and external short circuit (ESC) [ 12 ].
