Real time knowledge about the battery condition is very significant to ensure the performance of critical power system. however, existing methods of manual measurement or online battery monitoring system will require very complicated wire connection, long time installation/commission, professional technicians and also very high cost. Therefore, the investment is pretty huge. What's more, they do not have complete measurement data to precisely predict battery capacity.

More than Measurement Data!

BMS-3923 series battery monitoring system is an innovative solution to solve these problems. We apply new methods to measure battery condition with communication way of power line carrier (PLC). with multi-frequency measurement, users can analyze battery in all aspects including internal resistance, voltage, current, capacitance, temperature and so on. Based on Kongter's years experience for battery management, we build very mature mathematical model that will precisely predict battery capacity. this will in another hand reduce the time that we spend on capacity measurement using a battery load bank.

with APP or Web page access based on Cloud server, you could easily manage your batteries simply with a smart phone remotely. Periodically you will receive very detailed diagnostic report from Kongter indicating comprehensive data of your battery with suggestions and solutions in case of weak batteries.

 

System Architecture

 

System Composition

the whole BMS-3923 system is composed of two basic hardware components and one software component. Hardware will includeMonitoring Terminal (MT) &Control Unit (CU).

 

with Power Line Carrier (PLC) data transmission, measurement data will be collected by MT simply via battery straps and send to CU. It is no need to have extra time and money consuming communication cable or any other wireless data transmission. this enables the system to be installed in almost all battery systems with very simple wire connection and it is interference-free to battery system.

 

Monitoring Terminal (MT)

- Communication with CU:  PLC (optional: RS485)

- Cells connected per MT:  

One MT can be connected with 1, 4 or 6 depending on customers'

Requirement and different battery wiring structure onsite.

- Function:  

Test battery voltage, internal resistance, capacitance & temperature and send to CU via simply via power line carrier (PLC). It has battery equalization function.

- Model selection: 1-channel, 4-channel & 6-channel.

 

Control Unit (CU)

- Communication with server:  WiFi or GPRS

- Communication with MT:    PLC (optional: RS485)

- Function: 

Test string voltage, current and collect measurement data from MT simply via power line carrier (PLC). and it will send all data to cloud server via its built-in WiFi/GPRS module.
