Customized 50kWh DC Energy Storage System for China Tower — Enhancing Both Energy Efficiency and Safety
1. 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
4. 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."
5. Core Value Delivered
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.
