Battery On-line Monitoring and Maintenance System:
  Inuo-BMM

For these reasons, Inuosys has successfully developed an on-line test equipment that integrates real time battery voltage monitoring, online dynamic-ohm measurement, automatic discharge characteristics, Battery Maintenance and Voltage Dispersion Integrated Analysis (VOCD Integrated Analysis).

The Battery Monitoring and Maintenance System model, Inuo-BMM is not only capable of detecting poor battery performance and promptly revealing batteries with potential problems, it also has on-line battery maintenance functions. It can determine battery performance trends through battery voltage and dynamic-ohm measurement, perform on-line balancing and adjustment of the battery’s charge voltage when necessary. This enables easy battery maintenance and delays battery failure, thereby extending the battery’s useful life span.

At the same time, we also provide battery analysis software, which carries out calculation of actual battery capacity using our patented battery integrated analysis, a mathematical model technology based on battery voltage dispersion and other factors. This provides an effective measure for remote battery monitoring, maintenance, query and analysis.

System highlights

  • Uses high precision (16 bit) A/D to measure battery voltage, effectively reflecting changes in battery voltage
  • Uses on-line DC dynamic-ohm measurement method, accurately testing battery dynamic resistance changes on-line
  • Modularly designed system comprising main monitoring unit/host, battery voltage acquisition and maintenance module, communications module, data reception and release server
  • Main unit is able to communicate with our patented Wireless Voltage Acquisition modules
  • Built-in battery performance analysis model, including battery voltage analysis model and composite analysis model (VOCD Integrated Analysis)
  • Automatically monitors on-line cell voltage, battery bank voltage, charge and discharge current and temperature; provides fast and accurate data acquisition
  • Measures load capacity of each cell through dynamic instantaneous DC high-rate discharge; fast evaluation of battery performance
  • Measures battery bank capacity through static discharge of constant-current and displays various parameters and curves during the discharge process in real-time
  • Various communications modes: LAN, RS232, RS485, etc., meeting communications requirements of different systems
  • Multi-protection and alarm indication functions
  • Predicts the capacity and life expectancy of the battery by conducting complete and comprehensive failure analysis on the battery and its interrelated information continuously on the basis of probability distribution, fuzzy logic and artificial neural network etc.
  • Promptly determines battery’s operating status based on voltage and DC dynamic-ohm changes; if undercharge or overcharge trends are discovered in the battery, adjustments are performed on-line to restore the battery’s normal operating status and extend the battery’s useful life
  • Uses simple circuit design plan, under the premise of guaranteeing functions and performance; achieves high reliability and accurate results in recording
  • Performs on-line balancing and adjustment of battery’s charging voltage when necessary in order to achieve battery maintenance functions and delay battery failure, thereby extending the battery’s life span

 

Battery On-line Monitoring System: Inuo-BMS

Battery On-line Monitoring System, Inuo-BMS is a simplified version of InuoBMM. It has all the functions of Inuo-BMM except for battery maintenance for each individual cell. It is suitable for monitoring the performance of the various types of batteries. It is ideal and indispensable protective equipment for DC systems.
