Customized 50kWh DC Energy Storage System for China Tower — Enhancing Both Energy Efficiency and Safety

Project Overview

Client: China Tower (together with China Mobile, China Unicom, China Telecom, and China Broadcasting Network)

Application Scenario: Telecommunication equipment rooms

Core Product: 50kWh DC energy storage system

Cooperation Model: Energy Management Contract (EMC)

Core Value: Peak shaving and valley filling to reduce electricity costs, high-efficiency backup power supply

Customer Needs and Challenges

Telecommunication equipment rooms form the core foundation of the digital society. Their loads typically exhibit DC characteristics and demand an extremely high level of power supply continuity. Faced with the pressure of continuous energy consumption costs and the risk of service interruptions caused by grid fluctuations or failures, operators urgently need a more efficient, reliable, and economical energy assurance solution.

Our Customized Solution

We have developed an integrated DC energy storage system tailored to the DC load characteristics of telecommunication equipment rooms. This solution eliminates unnecessary energy conversion steps found in traditional AC energy storage systems, fundamentally improving efficiency.

System Core Components:

Battery Module: Safe and reliable foundational energy storage unit.

DC/DC Converter Module: Enables efficient power regulation between batteries and loads.

Local Controller: Manages intelligent charging/discharging and real-time system control.

Energy Management System (EMS): The intelligent brain that strategically executes advanced applications such as "peak shaving and valley filling."

Core Value Delivered

Significant Cost Reduction and Efficiency Improvement

System energy conversion efficiency reaches up to 95%, a 10% improvement compared to traditional AC energy storage solutions, greatly reducing energy loss.
Intelligent "peak shaving and valley filling" via the EMS charges during low-tariff off-peak hours and discharges during high-tariff peak hours, effectively reducing electricity expenses for base stations.

Enhanced Safety Level

In the event of power restrictions or sudden grid failures, the system seamlessly switches to emergency power mode, providing critical support for zero-interruption communication assurance.

Innovative Cooperation Model

As a pioneering model of cooperation between a national infrastructure provider and telecommunication operators under the "Energy Management Contract (EMC)" model, this project has established a new path for win-win collaboration, lowering the initial investment threshold for customers.
