In critical environments such as data centers, financial institutions, hospitals, and transportation hubs, UPS (Uninterruptible Power Supply) systems serve as the final barrier to ensure continuous power supply and stable operation of information systems. The battery pack, a core component of the UPS, directly determines system reliability. Traditional manual inspections are inefficient, lack precision, and struggle to detect issues like single-cell battery failure or thermal runaway in a timely manner. ARM embedded industrial computers, with their low power consumption, high reliability, and versatile interfaces, have become an ideal core platform for UPS battery management systems, enabling intelligent monitoring, edge computing, and remote maintenance.
The UPS battery management system consists of three layers: monitoring, edge control, and management platform.
Sensors for battery voltage, current, and temperature
Hall-effect current sensors
Environmental monitoring modules (temperature, humidity, leak detection, smoke detection)
ARM Embedded Computers BL340 Series act as the core, collecting data from battery monitoring systems (BMS), UPS hosts (via SNMP/Modbus), and environmental sensors
Performs real-time analysis and local storage
Visualized through Web HMI, SCADA, or DCIM platforms
Supports remote monitoring, alert notifications, and report generation
Integrates with enterprise CMMS (Computerized Maintenance Management System) and cloud platforms
Real-time collection of single-cell voltage, temperature, current, internal resistance, and insulation status
Supports discharge and capacity test curve analysis
Built-in SOC (State of Charge), SOH (State of Health), and RUL (Remaining Useful Life) algorithms to predict battery lifespan
Real-time alerts for anomalies (e.g., excessive voltage deviation, rapid temperature rise, or internal resistance degradation)
Local caching for ≥30 days, with support for data resumption after network disconnection
Multiple communication protocols: Modbus, SNMP, BACnet, MQTT, OPC UA
DO (Digital Output) triggers for audible/visible alarms, forced air conditioning, or load switching
Integration with DCIM/CMMS for closed-loop alerts and work order dispatching
TLS-encrypted transmission and SNMPv3 secure authentication
Supports remote OTA (Over-the-Air) upgrades and configuration snapshot recovery
Industrial-grade design, suitable for -20°C to 70°C indoor environments
Reduced Maintenance Costs: Automated monitoring replaces manual inspections, improving efficiency
Enhanced Reliability: Real-time alerts reduce the risk of UPS downtime due to sudden battery failures
Extended Battery Lifespan: Intelligent balancing and thermal management optimize battery usage strategies
Support for Digital Management: Integration with DCIM/cloud platforms enables centralized multi-site operations
As data centers and critical infrastructure demand higher power reliability, the intelligent evolution of UPS battery management systems has become an industry trend. ARM embedded computers, with their high performance, low power consumption, and multi-protocol compatibility, provide a robust hardware foundation for battery monitoring. They not only enhance system safety but also drive the digital transformation of smart data centers and energy management.
