Monitoring Controller

BTM Global battery monitoring system (BMS) provides battery health related data locally (in the battery or control room), and globally to specified locations, such as a central monitoring station, or even to unspecified locations on demand via Internet connectivity.

Using local alarm contacts, any detected alarm could be patched into the site Human-Machine Interface (HMI) device, or, using modbus protocol, data can be sent to SCADA.

The system report engine was designed with proactive maintenance programs in mind. The main goal of the reporting system is to provide the Maintenance Group with supportive information about the batteries between maintenance intervals, such as floating conditions, number and durations of discharges, recharges, or long-term trends indicating the rate of battery aging.

The data is presented in 3 levels. The first contains the primary data (e.g., voltages, current, float-current, AC- ripple, ambient and pilot temperatures).

The second level contains the calculated and predicted data (e.g., battery internal resistance, intercell strap resistance, battery float index, discharge / charge responses and predicted capacity).

The final level contains the trending data (e.g., floating voltage and current abnormalities, internal resistance of the jar, individual cells discharge and charge response and their trends over time).


  • Provides data over the internet
  • Supports standard web browsers
  • Accessible via mobile device
  • History and aging reports
  • Alarm communication
  • Cloud monitoring support
  • Large storage capacity
  • Handles large installations and complex topologies
  • Very fast data scanning

Data can be collected over the Internet (in HTML format) allowing the Maintenance Group to plan corrective actions before visiting a site. Overall, higher reliability in backup power is provided with less time, and with multiple site installations, management becomes significantly easier.

Operating under the most robust and reliable operating system, Linux, the controller can perform multi-level report generation, act as a web server and supervise various alarm and messaging capabilities.

The device is capable of acting as a Web Server for battery data, sending extended data as an e-mail attachment (upon request), notifying critical system conditions locally (contact closure), and remotely as email or fax messages. The device is also capable of creating and synchronizing (timer.change based) a mirror site on an internet server and communicating with central monitoring system using standard protocols such as MODBUS.
