Data Center Battery Monitoring System (BMS) Solution

Protect Your Data Center from Battery Failure

Battery failure is one of the leading causes of data center downtime. In many cases, a single degraded cell can compromise the entire UPS system—resulting in unexpected outages, costly downtime, and operational risks.

Traditional maintenance methods rely on manual inspections and periodic testing, which are often insufficient to detect hidden battery issues in real time.

DFUN Battery Monitoring System (BMS) provides continuous, real‑time visibility into your UPS battery performance—ensuring reliability, safety, and uptime for critical infrastructure.

Why Battery Monitoring is Critical in Data Centers

UPS batteries are the last line of defense during power failure
Battery issues account for a significant portion of unexpected outages
Manual inspection cannot detect early‑stage degradation
Increasing battery scale makes monitoring more complex and risky

A reliable battery monitoring system is essential for modern data centers.

Common Challenges Without a BMS

❌ No real‑time battery visibility
❌ Hidden battery degradation and failure risks
❌ High maintenance and labor costs
❌ Inability to detect thermal runaway or abnormal conditions
❌ Lack of centralized monitoring across multiple UPS systems
