Battery monitoring

Know your battery before it takes the UPS down

PEC's Battery Monitoring System (BMS) watches every block's voltage, temperature, and impedance — streaming into the cloud dashboard, SCADA, or SNMP you already run.

What the BMS tracks

Every block, every second — streamed into your stack

Per-block voltage

Track every block voltage continuously — spot weak blocks before they pull the entire string down.

Block temperature

Detect runaway heat early. Critical for VRLA in hot Thai environments where temperature halves battery life.

Impedance trend

Weekly impedance readings per block — IEEE 1188 lets you spot end-of-life months before a capacity test does.

Discharge events

Every grid dip and outage is logged — string current, duration, depth of discharge, and recovery curve.

Integration

Plugs into what your team already uses

Most of our customers already run SCADA or an NMS — our BMS is designed to feed those, not add another silo.

Cloud dashboard

Secure web dashboard for your ops team — view all sites in one place, with role-based access.

Alerts (email / SMS / Line)

Configurable thresholds route to the right person — on-call engineer, facilities manager, or vendor escalation.

SCADA / Modbus / SNMP

Feeds straight into your existing SCADA, BMS, or NMS — no isolated silo to maintain.

Historian + reports

5+ years of high-resolution history. Monthly summary report lands in your inbox, ready to forward to auditors.

Why it matters

Turn PM from reactive to predictive

Battery failure causes the single biggest category of UPS-related outages in Thai DCs — BMS catches it before the UPS trips.

Warranty claims with C&D are faster when you have continuous impedance history to point at the defective block.

Auditors and insurers accept BMS telemetry as proof of condition — shortens procurement and insurance renewal cycles.

Who should install

Customers who see clear ROI in the first year

Tier-III DCs

Uptime SLAs pay back BMS cost after a single prevented outage.

Banking + fintech

Audit-ready telemetry shortens both insurance renewal and regulator review.

Remote telecom sites

You find out before the truck roll is necessary.

Where do we start?

Send your single-line + UPS data — we scope the BMS rollout within 3 business days

BMS doesn't have to cover everything day one — start on one UPS or one string to prove ROI, then expand.
