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

A battery energy storage system (BESS) consists of key components, with the battery being crucial. 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?

A battery energy storage system (BESS) works by using batteries to store and release electrical energy. The HVAC (Heating, Ventilation, and Air Conditioning) system is an integral part of a BESS; 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 does a battery energy storage system (EMS) do?

A battery energy storage system (BESS) collects and analyzes performance data, making reporting and forecasting easy. It consists of critical components that make it safe, efficient, and valuable.

What type of batteries are used in stationary energy storage?

For this blog, we focus entirely on lithium-ion (Li-ion) based batteries, the most widely deployed type of batteries used in stationary energy storage applications today. The International Energy Agency (IEA) reported that lithium-ion batteries accounted for more than 90% of the global investment in battery energy storage in 2020 and 2021.

What is the role of HVAC in a battery energy storage system?

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.

How can battery racks be connected?

Battery racks can be connected in series or parallel to reach the required voltage and current of the battery energy storage system. These racks are the building blocks to creating a large, high-power BESS.
