Features


Versatile Equipment Compatibility

The Battery Monitoring Host supports a wide array of essential sensors, including battery sensors, Hall current sensors, DC voltage transmitters, and temperature sensors. This adaptability allows it to fit into diverse monitoring setups, delivering a holistic view of battery performance and surrounding environmental conditions. Whether monitoring small backup banks or large-scale industrial battery arrays, it adapts to the user’s specific needs without compromising functionality.


Dual Power Supply Reliability

Equipped with AC/DC dual power supply and wide voltage input support, the device maintains consistent operation even in unstable power environments. This flexibility eliminates downtime caused by power source fluctuations or failures, ensuring uninterrupted online battery monitoring—a critical advantage for facilities relying on continuous backup power.


Batch Monitoring Capability

Designed for scalability, the host supports multiple battery groups, making it suitable for both small and large installations. Its ability to oversee numerous batteries simultaneously streamlines monitoring efforts, reducing the need for multiple standalone devices and simplifying system management.


Active Cut-off Safety Function

The Active Cut-off Function is a vital safety feature that automatically disconnects the entire set of single battery collection modules if a single cell malfunctions. This prevents excessive discharge of the battery bank, protecting the batteries from irreversible damage and extending their overall service life.


Resilient Loop Communication

Each serial port features dual RJ45 interfaces to enable loop communication, ensuring that the failure or disconnection of any single section does not disrupt communication with the remaining modules. This resilience guarantees continuous data collection and system functionality, even in the event of partial hardware issues.


Standard Protocol Integration

Support for standard Modbus TCP/Modbus RTU protocol facilitates seamless integration with third-party dynamic environment monitoring systems and DCIM platforms. This interoperability eliminates compatibility barriers, allowing users to incorporate the Battery Monitoring Host into existing infrastructure without costly customizations.

FAQ


What types of batteries can the Battery Monitoring Host support?

The device is compatible with most industrial and backup battery types commonly used in critical power systems. It supports multiple battery groups, making it suitable for both small-scale backup banks and large industrial battery arrays in data centers, telecom base stations, and other high-demand environments.


How does the loop communication feature enhance system reliability?

The loop communication design uses dual RJ45 interfaces per serial port, creating a redundant communication path. If any section of the loop is disconnected or fails, data transmission continues through the alternate path, ensuring that the Battery Monitoring Host maintains contact with all connected modules. This redundancy eliminates single points of failure and guarantees continuous monitoring.


Can the host be integrated with existing DCIM systems?

Yes, the host supports standard Modbus TCP/Modbus RTU protocol, which is widely adopted in the industry. This compatibility allows for quick and seamless integration with most third-party DCIM platforms and dynamic environment monitoring systems, eliminating the need for custom software development or expensive hardware upgrades.
