What are critical components of a battery energy storage system (BESS)?

Summary

Battery energy storage enables electric grids to become more flexible and resilient. It allows grid operators to store energy generated by solar and wind at times when those resources are abundant. While the battery is a crucial component within the battery energy storage system (BESS) other parts are important as well, such as controller, battery management systems (BMS) or HAVC.

The BMS constantly monitors the status of the battery and uses application-specific algorithms to analyze the data, control the batterys environment, and balance it. If the BMS is the brain of the battery system, then the controller is the brain of the entire BESS. It monitors, controls, protects, communicates, and schedules the BESS’s key components.
