Location: Singapore Airport (one of Asia’s busiest hubs)
Scale: 1,200+ VRLA batteries across multiple UPS systems
Challenge: High maintenance costs, lack of real‑time monitoring, risk of unexpected downtime
Solution: DFUN PBMS2000 + DFCS4200 Backup Power Management Platform
Results: 60% maintenance efficiency improvement, early fault detection, extended battery life
Key takeaway: Transition from reactive to predictive maintenance with cell‑level BMS
In mission-critical facilities such as airports, data centers, and large campuses, backup power reliability is essential. Managing thousands of UPS batteries is increasingly complex, making a reliable Battery Management Systems essential.
As a leading provider of airport battery monitoring system solutions, DFUN recently completed a successful deployment at Singapore Airport – one of Asia’s busiest aviation hubs. This case study explains how DFUN’s battery health monitoring solution transformed the airport’s backup power strategy.
Why Battery Monitoring Systems (BMS) Are Essential
Modern BMS technology offers capabilities that go far beyond periodic manual checks:
Real‑time monitoring of individual battery voltage, internal resistance, and temperature
Intelligent battery health (SOH) analysis
Automatic fault detection and early warning for abnormal batteries
Remote centralized monitoring and data visualization
Historical data tracking and trend analysis
Project Background: Uncompromising Power Reliability Standards
Serving millions of passengers annually, Singapore Airport operates around the clock. Any power disruption could lead to severe operational delays and pose significant safety risks. To guarantee seamless operations, its UPS infrastructure demands:
24/7 uninterrupted operation to support critical systems.
Instant switchover capability to battery power during outages.
Proactive battery management to prevent failures before they occur.
Challenge: Managing Over 1,200 VRLA Batteries Across Multiple UPS Systems
To achieve this level of reliability, the airport needed to solve several critical pain points inherent in large-scale battery management:
High maintenance costs – Manual inspections of over 1,200 units are labor-intensive and time-consuming.
Difficult fault localization – Traditional string-level monitoring hides the degradation of individual cells.
Risk of unexpected downtime – Without continuous data, battery aging and impending failure cannot be accurately predicted.
Solution: DFUN's Intelligent Battery Health Management System
Recognizing that traditional methods were no longer enough, the airport turned to DFUN. We deployed a comprehensive solution featuring the PBMS2000 central controller – Centralized battery monitoring controller and DFCS4200 Management Platform – Remote visualization and alarm management, designed to deliver real-time intelligence across the entire battery fleet.
Using DFUN's advanced battery monitoring system – purpose‑built for high‑reliability environments such as airports – you achieve:
Comprehensive Management Architecture
Cell‑level monitoring – voltage, temperature, internal resistance for each battery
Centralized data acquisition via controller (PBMS2000)
Web‑based visual interface & dashboards
Remote monitoring over SNMP / Modbus
Flexible Deployment Options
Supports VRLA, Lithium, and Ni‑Cd batteries
Suitable for both new installations and retrofitting existing UPS systems
Scalable to meet the demands of large‑scale airport infrastructure
Easy integration with existing DCIM platforms
This enables comprehensive monitoring of data center batteries and ensures visual management of UPS operational status throughout the airport.
Project Achievements & Measurable Results
The project, successfully delivered in 2025, has yielded significant improvements:
Continuous monitoring of over 1,200 batteries across multiple UPS systems.
Proactive failure prevention – The system provides early warnings for abnormal batteries, allowing maintenance teams to intervene before failures occur.
Dramatic efficiency gains – Maintenance efficiency improved by over 60%, drastically reducing the need for labor-intensive manual inspections.
Frequently Asked Questions (FAQ)
Battery Monitoring vs. Battery Management: What‘s the Difference?
While often used interchangeably, battery monitoring and battery management serve distinct roles. Battery monitoring focuses on real-time data collection — tracking voltage, temperature, and state of charge to provide early warnings. Battery management, on the other hand, encompasses a broader scope, including charge/discharge control, cell balancing, and protection against overcurrent. DFUN’s solution bridges both: our monitoring system provides the data foundation that enables effective battery management for critical applications like airport UPS.
Can DFUN Battery BMS predict failures before they happen?
Yes. By continuously tracking internal resistance, voltage, temperature, and SOH, the system identifies abnormal trends and generates early warnings days or even weeks before a battery fails.
What battery types does DFUN Battery Management System support for data centers or airports?
DFUN BMS Solution supports VRLA, Flooded, Ni‑Cd, and Lithium‑ion batteries. It works with 12V, 2V, and other common cell voltages used in UPS systems.
How to choose the right battery monitoring system for airport UPS in 2026?
A reliable battery monitoring system for airport UPS should support multiple battery types such as VRLA, lithium‑ion, and Ni‑Cd to ensure full compatibility. It must provide real‑time, cell‑level monitoring with instant anomaly detection, rather than relying on periodic inspections. Seamless integration with UPS and DCIM systems via protocols like SNMP or Modbus is essential for centralized visibility and management. Advanced systems should also include predictive analytics (SOH and failure prediction) to prevent battery failures before they impact operations.
