Short Circut Protection in Batteries

Short-circuit protection is a safety feature, typically implemented through the battery management system or a fuse, that detects sudden, extreme current surges caused by accidental terminal contact or faults. The protection circuit monitors for abnormal current spikes, using metal-oxide-semiconductor field-effect transistors (MOSFETs) to automatically disconnect the battery from the load if a short occurs. Acting within milliseconds, short-circuit protection interrupts the circuit to prevent overheating, fires, device damage, and potential explosions.
