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 [16]. Kriston et al. divided the battery short-circuit current into 3 stages.
