The design and functionality of the battery fuse protect Li-ion batteries from potentially damaging and dangerous overcurrent and overcharging circumstances. 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.
ANL fuses may also fall short in voltage specifications for these types of batteries. A better option is the standard 10x38 fuses for smaller battery systems. These come with ceramic tubes filled with auxiliary materials, providing the high interrupt current ratings necessary for lithium battery systems.
Cell level fusing is just one of many safety measures that can be used in lithium-ion batteries. Other measures include thermal management, which helps to keep the battery at a safe temperature, and overcharge protection, which prevents the battery from being charged too much.
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.
These fuse wires are designed to activate at a specific current or temperature threshold, providing an additional layer of safety to your project. Overall, wire bonding is a viable option for implementing cell-level fusing in lithium-ion batteries, but it has a massive learning curve and again, requires specific, specialized equipment.

Cell Level Fusing
When we connect cells in parallel to increase the capacity we might also want cell level fusing. This fusing being by definition designed to disconnect a cell that for some reason is sinking or delivering high currents. The fusing can be inside the cell and sealed or external to the cell, sometimes both internal and external fuses are used.
