KofKaN BatteryGuard
Battery monitoring for backup and storage systems
Overview
Backup batteries are bought once and then trusted indefinitely, which is why so many fail at exactly the wrong moment. BatteryGuard is our monitoring design for stationary battery systems — telecom backup, UPS strings, solar storage and lead-acid banks — tracking pack and string-level voltage, current, temperature and estimated state of charge, and reporting health trends before capacity loss becomes an outage.
System capabilities
Pack and string monitoring
Voltage measured at pack level and, where wiring allows, per string to isolate a weak block.
Charge & discharge current
Bidirectional current sensing to see how hard the bank is worked in real conditions.
Thermal safety
Temperature monitored across the bank, with alerting on the imbalance that precedes trouble.
State of charge
Estimated from voltage and current integration, tuned to the chemistry in use.
Health trending
Capacity behaviour tracked over discharge cycles so degradation is visible before failure.
Fault reporting
Deep discharge, overvoltage and disconnection conditions raised as immediate alerts.
How it works
- 01Sense leads and shunt/hall sensors instrument the bank
- 02Controller samples voltage, current and temperature
- 03State of charge and health indicators are computed locally
- 04Telemetry and alerts publish over MQTT
- 05Dashboard tracks bank health across sites
Applications
- Telecom infrastructure
- Solar installations
- UPS and data facilities
- Industrial facilities
