Use Case — Failure Prediction
Stop guessing when a UPS battery will fail
Most facilities find out a string is weak the same way: it fails to hold load during an outage. Weltrom flags failure risk weeks in advance, from signals already in your BMS data.
Maintenance is stuck between too early and too late
Fixed replacement cycles waste good batteries or miss failing ones — condition data is the only way to know which string needs attention now.
The Problem
Three failure modes, one root cause
Unexpected failure
A weak string discovered only when the grid goes down and the UPS can't hold the load.
Premature replacement
Batteries pulled on a fixed schedule with years of usable life left, driving unnecessary spend.
Unnecessary waste
Both failure modes trace back to the same root cause: no visibility into real, string-level condition.
The Solution
Condition-based, not calendar-based
- Continuously track SoH, internal resistance, and float current — not just a periodic capacity test.
- Get an early warning weeks before a string would trip a BMS alarm.
- Replace the specific string that needs it — not the whole bank, not the whole fleet.
