The online battery equalization system features online equalization, activation, and monitoring capabilities.
Online Balancing Feature
Online balance each battery cell to ensure they operate at the same voltage state, preventing rapid aging of the battery pack due to overcharging or undercharging. Automatically adjusts each cell for balance, ensuring consistent performance among cells, thereby extending the battery pack's lifespan.
Online Activation Feature
The online balancing system can activate underperforming single batteries in real-time, preventing the battery bank from sulfating due to long-term float charging, extending the operational lifespan of the battery bank by twice as much, reducing environmental pollution, and offering good social benefits and environmental friendliness.
Online Inspection Feature
Battery internal resistance online testing function, battery capacity online testing function, and battery terminal voltage scanning function, which can completely replace the existing battery group internal resistance tester, capacity meter, and voltage scanner in the DC power system.
Online Inspection Function:
Battery warning online monitoring system's real-time monitoring of battery string includes: operating status, string voltage, charge/discharge current, single cell voltage, single cell battery negative temperature, voltage balance, battery string capacity, and discharge sustainable time.

Online Automatic Balancing Maintenance Function:
Battery预警Online Monitoring System with Online Automatic Equalization Maintenance Function: Automatically checks the voltage of individual battery cells while the battery is in float charging state, and performs staged supplementary charging for batteries set at the float charging voltage (long-term under-charging), as well as discharges over-charged cells to relieve the over-charging condition; ensuring voltage equilibrium during float charging to keep each cell in optimal activity. Effectively prevents battery dehydration due to long-term over-charging or sulfation due to long-term under-charging, while solidifying the battery and improving the energy absorption ratio, thereby extending the backup time and service life of the battery bank. Breaks the "bucket principle" so that even with failing batteries, it does not affect the performance of other batteries. Also provides a consistent "starting point" test platform for capacity and internal resistance tests during routine maintenance.

Online Automatic Pulsed Activation Maintenance Feature
The battery early warning online monitoring system automatically provides pulsating direct current to underperforming single cells in float charging mode, online activating them. It prevents crystallization and precipitation of internal plates within the battery, safeguarding against sulfation due to long-term float charging and eliminating potential safety hazards caused internally.

Data analysis and reporting features:
The battery warning online monitoring system is equipped with a powerful supervisory control and data acquisition (SCADA) software, which performs systematic analysis on monitoring and detection data. It plots total voltage, individual cell voltage, charge/discharge current curves, and capacity histograms, enabling the analysis of the health and discharge capabilities of the battery bank. It accurately identifies underperforming batteries. The system also analyzes and calculates the steady current and voltage accuracy, as well as the ripple coefficient, of the battery charging state data, providing a basis for charger performance analysis and maintenance.
The battery early warning online monitoring system can manually or automatically generate various data reports that meet customer requirements. Systems with supervisory control and data acquisition (SCADA) can also automatically generate a "Monthly Monitoring and Maintenance Report" in WORD format each month and save it directly to the user's folder.
