DFUN BMS Solutions for Data Center
Data center downtime is often traced back to a single weak battery cell. Traditional UPS monitoring only looks at string voltage, leaving individual cell degradation hidden until it’s too late.
DFUN’s cell‑level battery monitoring continuously tracks voltage, internal resistance, and temperature of every battery in your UPS system. You receive early alerts before a failure occurs, replace only the faulty cells, and eliminate unexpected outages.
Why Traditional UPS Battery Monitoring Falls Short
No cell‑level visibility String voltage can look normal even when individual cells are failing.
Reactive maintenance You only find out about a problem after the battery fails during an outage.
Costly & unsafe manual checks Monthly voltage measurements are time‑consuming and expose staff to high DC voltages.
No predictive data Without internal resistance trending, you cannot know which battery will fail next.
DFUN Solution For Data Center Solution | PBMS9000 + PBAT61
Monitor up to 6 battery strings (480 batteries total) with a single controller
Dual‑power input to avoid shutdown during power failure
Built‑in web server with visual dashboard
Comprehensive measurements per string: voltage, current, impedance, temperature, SOC, SOH, insulation resistance, and more
Flexible alerts via SMS or email
Multiple industrial protocols – Modbus‑TCP/RTU, SNMP, IEC61850, and MQTT (JSON) for easy integration
Multiple uplink options – 1x RS485, 2x Ethernet, and 1x 4G antenna port
6 DI ports (digital inputs) and 6 DO ports (sound/light alarm) for expandable control
Real‑world results from recent data center deployments
Thailand Data Center (6,100 batteries) ✅ DFUN BMS detected 23 cells with rising internal resistance over 6 months. The operator replaced them proactively and avoided a string‑level failure.
China Data Center (≈10,000 batteries) ✅ Predictive alerts reduced emergency call‑outs by 60% and extended average battery life by 18 months.
How It Works – From Data to Action
Continuous monitoring – Sensors on every battery measure voltage, internal resistance, and temperature (cell‑level).
Trend analysis – The BMS controller compares readings over time to detect abnormal degradation patterns.
Predictive alert – When a cell exceeds thresholds, the system sends an SMS/email alarm days or weeks before failure.
Proactive action – Your team replaces only the faulty battery(ies) during scheduled maintenance – zero downtime.
Recommended Products
PBMS9000 Battery Monitoring Controller
Centralized controller for up to 480 batteries (6 strings), SNMP/Modbus ready, built‑in web server.
Yes. Our system monitors batteries at the cell level, independent of the UPS brand. It connects to your existing monitoring via Modbus, SNMP, or RESTful API.
How often should I replace batteries in a data center?
Traditional rule of thumb is 3‑5 years. With DFUN BMS, you replace only cells that show elevated internal resistance or capacity loss – often extending average battery life by 2+ years.
