What is a battery energy storage system?

For this guide, we focus on lithium-based systems, which dominate over 90% of the market. 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.

What are the functions of CATL lithium-ion battery energy storage system?

The functions of CATL's lithium-ion battery energy storage system include capacity increasing and expansion, backup power supply, etc. It can adopt more renewable energy in power transmission and distribution in order to ensure the safe, stable, efficient and low-cost operation of the power grid.

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. A battery contains lithium cells arranged in series and parallel to form modules, which stack into racks.

What is a battery management system (BMS)?

Advanced BMS, such as EVESCO’s, monitor cells, modules, strings, and the entire system in real time, using algorithms to balance and control the battery, manage thermal conditions, and prevent thermal runaway. A well-designed BMS is essential for battery safety and longevity. The below picture shows a three-tiered battery management system.
