1. Project Overview

With the large-scale deployment of 5G networks, base station power consumption has increased by 3-4 times compared to 4G, posing significant challenges to traditional power supply solutions. As a technology leader in the communications energy sector, Huijue Technology Group has independently developed a new generation of integrated energy cabinets for 5G base stations. Leveraging three core advantages—“full-scenario integration, ultra-efficient conversion, and intelligent simplified operation and maintenance”—this solution empowers operators to achieve triple breakthroughs in “site deployment speed, spatial efficiency, and energy utilization.”

2. Project Details

Application

The Outdoor Integrated Energy Cabinet is a unified enclosure integrating intelligent power systems, AC/DC distribution, FSU environmental monitoring, smart batteries, and lightning protection/grounding. It provides outdoor operational environments and safety management for base stations. Primarily deployed in diverse outdoor scenarios such as street-side locations, mountainous areas, railway corridors, and high/low-temperature environments, it addresses customer needs for energy conservation, rapid deployment, and multi-scenario adaptability. This project primarily resolves power supply challenges for telecom base stations.

Functions:

★ Grid Peak Shaving

Limits total input power and phase-specific input power, supporting local or remote parameter configuration. The power system adapts to load fluctuations of base station communication equipment by limiting power or supplementing discharge via energy storage batteries. This reduces peak load demands on grid input capacity, achieving grid peak shaving.

★ Off-Peak Power Usage

Features off-peak power usage functionality. Configured based on daily peak/off-peak electricity rates, it utilizes off-peak grid power (battery storage) during low-demand periods and discharges battery power (without grid usage) during high-demand periods to reduce electricity costs. The basic integrated energy cabinet system can utilize existing network batteries for off-peak power usage.

(1) Supports configurable peak/off-peak rate time periods, battery SOC (State of Charge) settings, and discharge cutoff voltage settings.

(2) The system provides an “On” and “Off” switch for peak-shaving functionality, enabling local or remote activation/deactivation.

★ Stacking Functionality

Supports stacking functionality. Rectifier modules and photovoltaic modules of specified models can be mixed and matched in slots to rapidly achieve stacking capability, centrally managed by the power monitoring module. The power system supports unified management of both rectifier modules and photovoltaic modules.
