Compact & Intelligent Battery Monitoring Solution for Critical Power Systems

The YX-M12-W03 Battery Online Monitoring Device is a professional industrial-grade solution designed for high-density battery monitoring in backup power systems. Based on a Cortex-M4 core processor and μ cos-II operating system, this device offers robust performance for real-time data collection. It is engineered to monitor single-cell voltage, internal resistance, temperature, and group current without the need for a local display, making it ideal for space-constrained or centralized management scenarios. The device supports passive equalization and integrates advanced diagnostic models to predict battery health and extend service life.

• All-round Precision Monitoring: Accurately collects critical parameters including single-cell voltage, internal resistance, pole temperature, group voltage, charge/discharge current, and ambient temperature. Utilizes imported high-precision chips to ensure data reliability for battery health assessment.
• Intelligent Battery Diagnosis: Built-in expert diagnosis model for battery performance analysis. It accurately predicts the State of Charge (SOC) and judges battery performance, providing targeted maintenance suggestions to prevent failures before they occur.
• Passive Equalization & Activation: Features built-in passive equalization charging and desulfurization activation functions. This helps optimize battery performance, mitigate imbalances between cells, and significantly extend the service life of the battery pack.
• Robust Communication & Networking: Equipped with 3 SBUS ports, 2 RS485 interfaces, and 1 Ethernet port. Supports standard protocols (MODBUS/RTU, MODBUS/TCP) for seamless integration with SCADA systems and third-party platforms, enabling centralized remote management.
• Industrial-grade Reliability: Designed with high EMC and isolation circuits to withstand harsh industrial environments. Features a built-in "watchdog" circuit for automatic recovery under any anomalies, ensuring 24/7 stable operation.
• High Stability Design: Certified by national Open Laboratory, it boasts an MTBF exceeding 100,000 hours and 2000VAC insulation withstand voltage. The fanless design ensures silent operation and maintenance-free reliability in critical infrastructures.
