Outline 
 HDGC3920 battery monitoring system is mainly used for railway traction substation, communications room and the battery status of the UPS power monitoring and analysis, is the battery internal resistance, the terminal voltage as the main monitoring parameters online monitoring systems for monitoring battery failure, the battery performance status. Found that severe performance degradation fault battery alarm immediately; track battery performance balance, maintenance provide the basis for the battery "fine". 
 Design Features 
 A. Unique resistance test, to avoid the impact of the battery is damaged and the system test. 
 Two. Line discharge by measuring the battery voltage, current, and calculate the discharge capacity, according to the set discharge requirements, and automatically prompts the user to the end of the discharge. 
 3. Has a network alarm, alarm sound and light alarm function. 
 4. Can be 4-way, 8, 24, 32, 48, 54, 108, 256 extend. 
 5 Automatic inspection battery internal resistance, the terminal voltage, and automatically record the monitoring data. 
 6. Controlled single inspection, the inspection the battery internal resistance and terminal voltage, and automatically record test data. 
 7. Balance, automatic monitoring of the performance of the battery pack to diagnose battery failure, the automatic alarm when the battery fails. 
 8. Automatic analysis of the internal resistance trends to predict battery life. 
 9. Performance status of single cells and batteries can be used in the field observations, can also be observed in the data center. The flag is clear, intuitive display. 
 10. Field testing without human intervention, to avoid a short circuit caused by manual detection of misuse, electric shock load power failure risk. 
 11. Isolated, test the circuit, both from the user equipment interference, does not affect the normal operation of the user equipment and batteries. 
 12. Battery resource management a comprehensive digital and information technology. 
 13, the battery resources make full use of, the provincial capital, the environmental benefits. 

 Function 
 Through GPRS or Ethernet RMON mode, the application powerful and comprehensive PC system management software, through the following features real-time battery management: 
 1, regular internal resistance detection 
 The system can be set to automatic timing detection of the battery internal resistance, the lowest setting for 10 minutes. Also on the server on the internal resistance of the entire group of cells or single cells were detected. Internal resistance in the test at the same time, the battery voltage value can be measured simultaneously. 
 2, the voltage monitor functions 
 The system parameters of voltage, current, positive and negative temperatures, the monomer battery voltage of the battery pack inspection. Inspection of the interval can be set, the shortest interval of 20 seconds. 
 Capacity monitoring function 
 When the discharge or charge the battery pack, battery monitor, automatic capacity testing. Test the discharge capacity and charge capacity of the battery and battery pack. Charge and discharge process on the remote observation. Be in line with the disgusting discharge, the whole process of monitoring the discharge voltage and discharge current of the battery pack and battery voltage changes. 
 4, the alarm recording function 
 Battery voltage, cell voltage, battery internal resistance, temperature setting on the lower limit of extreme value. When the monitor detects that a parameter is out of the upper and lower limit set by the monitor sound, light, alarm and event record. Users can find the exception of the state of the battery pack. 
 5, battery quality analysis and report analysis capabilities 
 B / S structure database management 
 Long-term tracking and monitoring of the internal resistance and voltage of the battery, and the formation of the monthly, quarterly, annual monitoring reports, and complete control of battery operation and maintenance status.
