PITE 3923 Battery Monitoring System                                                                                 Catalog

Our Advantages

1. Very simple wire connection, easy-going installation and commission onsite 
• PITE 3923 adopts the technology of Power Line Carrier (PLC) for data transmission. It takes advantage of communication circuit with battery string itself. Data will be transferred via battery straps and power line, no need to connect extra wires or cables for data transmission.
• We use cloud computing platform for data management. Users do not need to purchase server or install server software by themselves. Just one login account and password from PITE will enable user to view everything about their battery condition simply with a smart phone.

2. PITE’s advanced mathematical model, consistent and precise measurement
• PITE has patented technology of multi-frequency measurement based on our years experience for battery management. And we have built very mature mathematical model that will precisely predict battery capacity (SOH).
• Customized solutions to meet different users in various applications. We have different types of monitoring terminals. They can be that can be connected to 1 cell, 4 cells or 6 cells each. Different terminals could be used for the same battery string. This makes it very convenient and flexible for connection with different types and wiring structure of batteries.  


3. Cloud server + mobile communication

• All you need is a smart phone to view battery status and all detailed information.
• Timely SMS warning info keeps you alert for lag-out or weak batteries.  

4. Smart and convenient methods for battery management
• Complete monitoring and recording for voltage, internal resistance, temperature and periodical monitoring for charge/discharge current. It helps you find out lag-out batteries beforehand. 
• In case of power grid outage or manual switch-off of power grid for maintenance, system will automatically switch to discharge monitor. And it will record discharged Ah and voltage/temperature changes during discharge. This will further help judge the lag-out batteries.
• In case of battery malfunction, system will automatically send warning message to technician for immediate action.
• Map orientation of battery sites will help technicians reach site conveniently. 

5. Unique technology for system resting
• Each MT gets very low power from batteries, no harmful to batteries that are monitored.

6. You not only get measurement data, you get solutions
• Every month, you will get a very detailed analyzing report from PITE. This report will analyze all battery conditions completely. In case of battery failures, we will provide solutions in the report. This will enhance the reliability of your system. You don't also need to go the site for manual inspection and measurement. It saves your time and manpower.  

 

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.

PITE 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 PITE’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.     


System architecture


System Composition

• The whole PITE 3923 system is composed of two basic hardware components and one software component. Hardware will include Monitoring Terminal (MT) and Control Unit (CU).

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


Control Unit (CU)

• Communication with server:   WiFi or GPRS
• Communication with MT:   PLC (optional: RS485)
• Function:  Test string voltage and 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.  





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).
 


Onsite installation of measurement cables

Patented clip is very convenient for fast connection with battery posts. All you need is to loosen the screws on battery posts and quickly fix the clips on each post. This greatly simplifies onsite installation. Temperature sensor is built-in the clips to measure temperature of each cell.

NOTE:

  • • There are two optional ways of communication between MT and CU: PLC and RS485.
    Where it is using PLC (Power Line Carrier), you will not need extra cables between each MT and U for data transmission. The data recorded by MT will be transferred via the battery power line to Control Unit directly. This simplifies the wire connection and makes it very easy going for onsite system installation.
    When it is using RS485 for communication, there will be a 2 pin communication cable connected between each MT and CU.
  • • There are 3 models of MT: 1-channel, 4-channel and 6-channel for connection of 1 cell, 4 cells and 6 cells respectively. They will be adopted depending on customers’ requirements and different wiring structure onsite.
  • • For PITE3923-1/A, the MT could be alternatively installed outside or inside the battery. When it is installed inside, it will need remolding of batteries.
