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.
Battery Energy Storage System Structure The storage device is controlled by the Monitors & Control module, also referred to as BMS (Battery Management System). It is a real-time monitoring system which consists of electronic circuit apparatus that will monitor the state of the battery.
Inside the control cabinet, there are many components from servo drives to PLCs and terminal blocks. Power is typically supplied to the cabinet from the top portion. There is an AC power distribution system (PDS), associated with the main power breaker. The PDS, transfer power to all components that require AC power.
Control cabinets are vertical enclosures with servo drives and other electromechanical components that control or monitor machinery and factory systems associated with it. The control cabinet is a stainless steel box, which can either be wall-mounted or a standalone module on the floor.
The EMS will also collect and analyze BESS performance data, making reporting and forecasting easy. These are the critical components of a battery energy storage system that make them safe, efficient, and valuable.
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.
