How to Properly Protect a BESS Power Circuit from Overcurrents
In a battery energy storage system (BESS), circuit protection becomes necessary when each of the levels--from the cells to the racks--form a combination of energy.
Circuit protection must be adequately sized to prevent catastrophic failure. The optimal circuit protection component to use depends on the
- system voltage,
- system nominal current,
- time constant,
- withstand rating of the interconnecting components,
- ambient conditions, and
- location of the component within the system.
This paper discusses the different fault-prone points of a BESS, and how to adequately size the fuse for optimal overcurrent protection.
