[PDF Version](Image: Eaton.) One of the most important components in the BMS is the primary fuse, which provides overcurrent protection to the whole battery pack. The BMS also includes a self-control fuse further down the circuit, attached to the BMS controller, that provides an additional layer of protection.
Overcurrent protection can be achieved by using current fuses or battery fuses. Current fuses protect against overcurrent. On the other hand, a battery fuse is used in a Battery Management System (BMS) as a secondary protection element. In case overcurrent occurs while using the device, the fuse element will open and cut off the circuit.
Battery fuses are designed to protect Lithium-ion (Li-ion) batteries from potentially damaging and dangerous overcurrent and overcharging events. The devices safeguard components, equipment, and people from risk of fire and electric shock. Overcurrent protection can be achieved by using current fuses or battery fuses.
