How to do short circuit test on lithium battery pack
Internal Short Circuit in a Lithium-Ion Battery
During an internal short circuit of a battery, the two electrode materials are internally and electronically interconnected, giving rise to high local current densities. Internal short circuits may occur in a lithium-ion battery due to, for instance, lithium dendrite formation or a compressive shock.
