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.
We can use passive fuses and pyro fuses in battery design. Select a fuse rated double as continuous current (e.g. initially take 400A fuse for 200A continuous current) and draw the load profile next to 50% of the fuse breaking current-time chart to check if pulse currents can be carried by the fuse without aging.
For quality assurance, some reliable and safe brands to consider are Blue Sea Systems and Little Fuse. In large battery banks, the fuse selection becomes even more critical. UL 248-14 certification fuses are advisable. Smaller style fuses mentioned earlier like the 10x38 fuses, may not suffice.
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.
They often lack the necessary interrupt current rating for a lithium battery bank, posing a significant risk. There are various fuses to consider, such as blade-style, ANL fuses, and standard 10x38 fuses. Blade-style fuses, common in automotive applications, aren't typically suitable for lithium battery systems.
Check the contactor-fuse coordination for normal operation, overloads and failure currents. The fuses in a battery pack protect the battery and the other electrical components against high currents. There are special off-the-shelf components similar to 12V starter battery fuses. However, EV fuses are rated for high voltage and traction currents.
Selecting the right fuses for your lithium battery system is crucial for safety and reliability.
