Robotina Battery Monitoring System

System Architecture

General description

A battery forms an essential part of any power back up system. A battery failure can lead to a catastrophic disruption of business activities. A proactive method of identifying potential battery failures will prevent backup systems from failing, ensure on time maintenance and enhance the life span of batteries The Robotina Battery Monitoring System provides an efficient & reliable solution to monitor VRLA batteries providing critical data at an individual cell level

System components


Battery Sensor (BM-CR-XX, BM-CS-XX)

Battery cell sensor is specially designed as highly integrated smart sensor module for batteries. It can quickly and accurately measure:

  • Cell Voltage
  • Cell Temperature
  • Cell Internal Impedance
  • Individual Cell SOC(State of Charge)
  • Individual Cell SOH(Section of Health)

Cell sensor use specified isolated communication bus, and multiple sensors can be very easily cascaded to realize the real time monitoring of the entire string of batteries.

String Sensor (BM-SS-A1)

String sensor will measure following parameters:

  • String Voltage
  • String Current
  • Balancing function extends battery life
  • Batch Set Address
  • Charging and discharging status
  • Up to 120# BM-CR-XX or BM-CS-XX
  • RS-485, Modbus - RTU protocol

Hall Sensor

Hall sensors are used to measure the current of individual string in the battery packs. Hall sensors having following rated:

  • BM-HS-100 Measuring range: 0-100A
  • BM-HS-200 Measuring range: 0-200A
  • BM-HS-400 Measuring range: 0-400A
  • BM-HS-800 Measuring range: 0-800A
  • BM-HS-1000 Measuring range: 0-1000A


  • Industrial grade reliability
  • Easy instalation
  • Update & upgrade from Cloud
  • Alarms & log
  • One controller per UPS
  • Max. 4 battery strings with one controller
  • 4 outputs for battery disconnection/alarm
  • Optional: Connection of temperature sensors (directly) or temperature/humidity sensors (on bus)
  • Optional: connection of RFID/Digital key reader for confirmation of physical check by staff
  • Unlimited number of controllers in network

Connection to SCADA

  • OPC (on ethernet)
