From an internal structure perspective, the containerized energy storage system typically consists of two parts: the battery compartment and the electrical compartment.
One or more battery clusters, energy management system EMS, thermal management system, fire safety system, etc., form a DC side energy storage battery compartment. Combined with bidirectional PCS, it can form an AC output energy storage battery compartment. 1 Basic structure of battery compartment
The energy storage system supports functions such as grid peak shaving, frequency regulation, backup power, valley filling, demand response, emergency power support, and reactive power compensation. The 2.5MW/5.016MWh battery compartment utilizes a battery cluster with a rated voltage of 1331.2V DC and a design of 0.5C charge-discharge rate.
A stationary Battery Energy Storage (BES) facility consists of the battery itself, a Power Conversion System (PCS) to convert alternating current (AC) to direct current (DC), as necessary, and the “balance of plant” (BOP, not pictured) necessary to support and operate the system.

How does an energy storage inverter work?
Energy Storage Inverter: Each battery compartment connects to a 2500kW-PCS, enabling bidirectional energy conversion between the battery system and the grid. The battery compartment employs a 20'GP non-standard container measuring 6058mm×2550mm×2896mm, housing a total of 12 battery clusters, resulting in a total system capacity of 5.016MWh.
What are the fire-fighting facilities used for energy storage battery compartments?
The fire-fighting facilities used for energy storage battery compartments are generally as follows: first, ventilation devices; Secondly, combustible gas detectors; Thirdly, fire extinguishers; The fourth is the fire sand box; The fifth is the fire alarm system; The sixth is the gas automatic fire extinguishing system.
There are currently two main structures for battery compartments: containerized and commercial cabinet type. The most basic unit of an energy storage system is the battery cell, and multiple battery cells combined together form a battery module.
