Battery Management Systems

A battery management system (BMS) is a set of electronics designed to monitor, control, and optimize a battery’s performance as well as detect and respond to unsafe conditions.

A BMS can provide first responders with useful information relating to the current state and function of battery banks. It can also provide automated intervention. As a battery heats up, the BMS can electrically isolate the unit and initiate exhaust venting and airflow to create a negative thermal balance. This will minimize heat transfer and inhibit escalation and propagation.

However, a BMS is not foolproof. Incidents may occur due to system programming errors, various abuse factors, and the complexity of BESS. Although a BMS can provide operational intelligence and may initiate protective action, these systems should be considered as a component of your situational awareness. It is essential that you verify BMS data and use direct observation to form a complete operational picture.
