Battery Energy Storage Cabinet

Product Overview

The Huijue Network Energy Storage Battery Cabinet is an energy storage solution based on lithium battery that has been created for energy storage for commercial and industrial facilities, telecommunication systems, solar energy storage, micro-grids, and off-grid energy generation.

This cabinet makes use of LiFePO4 batteries as its energy storage system, and integrates batteries, BMS, protection system, thermal management, and communication within one cabinet. Depending on the nature of the project, this cabinet can be linked to PCS, inverter, PV system, or EMS to make up an energy storage system.

This cabinet is not offered as just a battery cabinet, but as a modular energy storage solution, enabling project developers and system integrators to choose the voltage level, capacity, cooling system, and communication protocols as per the requirement of the project.

Product Highlights

• High Safety LiFePO₄ Chemistry – Batteries that use lithium iron phosphate chemistry that have high safety and cycle stability are used for stationary energy storage.
• Modular Batteries – Modules can be grouped to have different voltage and capacity combinations.
• BMS Integrated – Monitors the voltage of each cell, the temperature, current, SOC and SOH of each cell.
• Spacious Cabinet – Batteries and other electrical components are installed in cabinets.
• Multiple Layer Protection – There are battery protection and electrical protection layers against overvoltage, overcurrent, short circuit and temperature abnormalities.
• Ready for System Integration – Has design features to be integrated with PCS, EMS, solar PV, grid power and other energy systems.
• Flexible Cooling – The cooling system can be selected based on battery capacity, environment and operating conditions.
• Customized Configuration – Battery capacity, voltage, cabinet size, interfaces and internal structure can be customized.

Battery Cabinet Structure

Cabinet design revolves around the battery modules instead of just filling the cabinet with battery packs. The internal structure can be designed depending upon the requirement of the capacity and voltage.

Battery Modules
LiFePO4 battery modules are placed in a modular fashion so that the total energy capacity can be increased depending upon the application requirement.

BMS
The BMS system takes care of the status of each battery module and manages the charging and discharging operation as well as provides protection.

Power Distribution
The busbar, breaker, fuse, contactor, and other electrical components are used to distribute the power from battery system to outside PCS or load.

Thermal Management
The cabinet can either have the natural cooling system or active thermal management system depending upon the battery capacity.

Communication Interface
The communication interface enables exchange of battery status and alarms with PCS or EMS or any other external platform.

Technical Specifications

Final electrical and mechanical specifications depend on the selected battery configuration and project requirements.

Designed for Different Energy Storage Scenarios

Commercial & Industrial Energy Storage

The battery cabinet can work together with the PCS and EMS units to store the electricity and then release it according to the load curve of the facility. It is capable of providing peak shaving, load shifting, demand management, and emergency backup.

In case of large-scale implementation, several cabinets can work simultaneously to provide additional capacity for energy storage.

Solar Energy Storage

In combination with a photovoltaic system, the battery cabinet can store additional PV electricity when the amount of solar production is high and then release the stored electricity when the PV production is low.

Thus, the battery cabinet can be used in solar+storage facilities where self-consumption is crucial rather than feeding additional PV electricity into the grid.

Backup Power for Telecommunication Sites

At telecommunication sites, the battery cabinet is used as a source of energy supply for the telecommunication equipment in case of electricity failure or unstable power supply conditions.

It can be designed based on the voltage level at the site, the telecommunication load, the backup power time needed, and the available space for installation; thus, it is appropriate for individual telecommunication sites and for telecom power applications.

Microgrid/Off-Grid

The battery cabinet can act as an energy storage solution for a microgrid/off-grid power system with renewables (solar, wind), generators, and PCS.

The storage compensates for the intermittent availability of the renewable energy sources and acts as the power source when there is no generation from the renewable source.

Battery Management

The integrated BMS continuously supervises the battery system while charging and discharging.

Some of the important parameters being monitored are:

• Cell voltage
• Battery voltage
• Charging current
• Discharging current
• Cell temperature
• SOC
• SOH
• Battery alarms
• Protection status

The BMS is capable of communicating with the external PCS or EMS in such a way that the conditions of the battery operations can be included in the energy management system.

Flexible Cabinet Configuration

There cannot be any one battery capacity that is applicable for all energy storage projects. Huijue Network can customize the cabinet based on the specific project, which includes:

• Energy capacity needed
• Voltage of the system
• Quantity of battery modules
• Maximum discharge power
• Duration of backup
• Cooling needs
• Cabinet size
• Installation environment
• PCS requirements
• Communication protocol

This can lead to the creation of small battery cabinets for telecom backup power or a large battery cabinet for commercial and industrial energy storage.
