Lithium battery packs have high energy density and require accurate and reliable overcurrent protection. Selecting the right ESS fuse is critical to the safety of energy storage systems.
First, calculate the rated current. The fuse should match the maximum charge and discharge current of the lithium battery. Generally, it is selected as 1.1 to 1.3 times the normal working current.
Second, confirm the voltage level. With the popularization of high-voltage energy storage systems, fuses must meet DC 1000V or 1500V requirements.
Third, focus on breaking capacity. The fuse must be able to cut off the maximum short-circuit current of the battery pack to prevent fire and explosion risks.
Fourth, choose the structure. For large-current battery packs, bolt-on fuses are recommended. For small and medium modules, PCB mount or cylindrical fuses can be used.
Fifth, consider temperature influence. The working environment of energy storage cabinets is relatively closed, so fuses with low temperature rise should be selected.
