The WBMS wireless battery monitoring system is a complete solution for monitoring critical parameters of battery systems in real time. Parameters monitored include string voltage, string current, ambient temperature, cell/unit voltage, impedance, and temperature. The WBMS is compatible with VLA, VRLA, and Li-Ion battery types.

The system is designed as a modular solution, allowing multiple (up to 16) battery strings to be monitored by a single Control Unit (CU). Installation is fast and easy. The WBMS utilizes PLC (Power Line Carrier) communication between components which utilizes the battery connections for data transfer, eliminating excessive wiring. Also, the system can be installed while the battery is online by using connectors which clamp on to the cable or bus bar, eliminating the need to disconnect battery hardare.

Included with every WBMS is access to web-based battery management software which allows remote monitoring of the battery system, either from mobile app or web browser. Information can be communicated via either cellular (GSRP) or local Wi-Fi connection. Alternatively Modbus protocol can be used for third party integration to existing software.

Web-Based Data Management Software

Battery Management Software Displays and records string voltage, string current, cell/ unit voltage, impedance, and temperature for all battery systems Calculates capacitance and battery state of health Viewable from any web-browser or available on mobile app Generate PDF reports Timely SMS warnings in the event of alarm condition

WBMS System Configuration

Control Unit (CU) Measures string voltage and current. Built in GRPS or Wi-Fi for communication to server. Controls MT for cell data collection. Monitoring Terminal (MT) Test battery voltage, internal resistance, capacitance, & temperature. MTs communicate via PLC (power line carrier). Current Clamp (CT) Customized DC current clamp w/cable for measuring battery string discharge and charge current. Powered by the CU. Connection Hardware The wires from the MT can connect to each battery via either ring terminal or clamp. The clamp attaches to the cable or bus bar, eliminating the need to disconnect battery hardware.
