company news about Application of energy storage fuse

        Energy storage fuses are mainly used in three places: 1) battery module 2) battery cluster/battery pack 3) AC to DC conversion inverter.

        Inside the cells, each cell is protected by DC fuses on the positive and negative terminals to isolate the cells in the event of any internal short circuit. In inverters, there are sensitive electronic devices, so strong protection against energy surges is required.

       Energy storage batteries have high safety requirements, and circuit protection is very important. In order to provide the longest possible battery discharge time, the capacity of the battery pack is increasing. Each battery represents an energy source. Any failure in the system can result in a large amount of energy being dumped at one time and can create a variety of personnel and equipment hazards.

        The DC combiner box needs to use a fuse with the largest possible breaking current to protect the battery. The DC combiner box is a critical location susceptible to large DC overcurrent faults, where the outputs of multiple battery racks are combined to feed the inverter. Usually in this position, the output string of the battery is protected by a DC fuse with the highest possible DC rated breaking current.
