What is BMS technology for stationary energy storage systems?

This article focuses on BMS technology for stationary energy storage systems. The most basic functionalities of the BMS are to make sure that battery cells remain balanced and safe, and important information, such as available energy, is passed on to the user or connected systems.

What is a battery management system (BMS)?

The BMS constantly monitors the status of the battery and uses application-specific algorithms to analyze the data, control the battery’s environment, and balance it. This is critical for the thermal management of the battery to help prevent thermal runaway.

What are the critical components of a battery energy storage system?

In more detail, let’s look at the critical components of a battery energy storage system (BESS). The battery is a crucial component within the BESS; it stores the energy ready to be dispatched when needed. The battery comprises a fixed number of lithium cells wired in series and parallel within a frame to create a module.

How does a battery energy storage system work?

The HVAC is an integral part of a battery energy storage system; it regulates the internal environment by moving air between the inside and outside of the system’s enclosure. With lithium battery systems maintaining an optimal operating temperature and good air distribution helps prolong the cycle life of the battery system.

What is BMS balancing?

The balancing approach is typically used to classify BMS types, although other design aspects play important roles, such as different approaches to state estimation and information flows. Cells, or electrochemical cells, like lithium-ion cells are the smallest unit of energy storage within a pack.

What makes a good BMS design?

The single most important factor in BMS design is the team and its expertise. Traditionally, BMS design has been the domain of electrical engineers, who are indeed best placed to design the circuitry, but don’t typically have much knowledge of the inner workings of batteries.
