Frequently Asked Questions about Battery Energy Management Systems
An Energy Management System (EMS) for a Battery Energy Storage System (BESS) is an advanced control supervisory system designed to optimize the performance, efficiency, and lifespan of battery storage units by managing all the electrical components that make up a BESS including the battery management systems, power conversion systems, support equipment, and more.
The EMS oversees the charging and discharging cycles, manages energy flow to and from the grid or other connected systems, and ensures that the stored energy is utilized in the most effective manner. An EMS will respond to the system (grid) operator’s demand for active and reactive power by optimally discharging the stored energy by ensuring a balanced output from the individual storage assets and their respective power conversion systems while monitoring the system for anomalies and adjusting accordingly. Similarly, the EMS manages the charging of the overall site respective of the individual battery units’ capacity.
Additionally, it can incorporate predictive analytics and real-time data monitoring to enhance decision-making processes, maintain system health, and improve overall energy reliability and sustainability.
Thermal runaway in a BESS refers to a dangerous and uncontrollable situation where the temperature of the battery cells increases rapidly and leads to a chain reaction of further heating. The excessive heat generated during this chain of events can cause the electrolyte and other materials to break down, releasing more heat and potentially leading to the ignition of flammable gases. This can quickly spread to adjacent cells, creating a cascading effect that dramatically increases the risk of fire or explosion.
There are several triggers that can potentially cause thermal runaway in batteries. It is primarily the result of internal short circuits caused by degradation effects of the electrodes. Overcharging or over-discharging can lead to these degradation effects. External heat sources, electrolyte breakdown, and poor battery management systems can also contribute. Over time, the conditions that contribute to thermal runaway may also increase as the battery ages and wears.
Thermal runaway in Battery Energy Storage Systems (BESS) can pose serious safety, environmental, and operational risks. From an operations standpoint, thermal runaway often results in significant damage to the battery system and cause significant downtime to repair and replace the component(s). The impact to the plant can either result in a full outage or a derate during the recovery period. In most new installations, battery components are separated into blocks so that damage resulting from a thermal runaway will only impact a small portion of the site.
By closely monitoring various parameters within the BESS, an Energy Management System (EMS) can detect early warning signs of conditions that could lead to thermal runaway. When a potential risk is identified, the EMS can then take preventive actions.
Fully integrating an EMS with cell-level sensor information and sophisticated diagnostic software can further reduce the risk of thermal runaway in battery energy storage systems. Finally, AI-based solutions integrated into the automation system add the potential of an extra layer of speed and robustness to thermal runaway avoidance.
