Neglecting battery balancing issues in energy storage systems
In the operation of energy storage systems, some companies neglect battery balancing maintenance, leading to increased voltage differences between individual cells within the battery pack. This results in rapid capacity degradation, decreased charging and discharging efficiency, frequent system alarms, and even safety hazards. Real-world examples show that a large energy storage plant suffered direct economic losses due to the failure to promptly monitor battery balancing, causing premature retirement of some battery packs.
What is battery balancing?
Battery balancing refers to controlling the charging and discharging process of each individual cell to maintain a consistent voltage across the battery pack, thereby extending battery life and improving system stability. Balancing technologies include active and passive balancing, with B2B applications primarily focusing on high-precision instrument testing and maintenance.
How to maintain battery balance
Battery equalization test process
Preliminary diagnosis : Use battery pack testing equipment to conduct an overall condition assessment of the energy storage battery.
Individual cell voltage acquisition : The voltage of each individual cell is acquired using a portable battery pack equalization and maintenance instrument PBM-PW-F-3605 or PBM-PW-F-6405 .
Equalization Analysis : The software analyzes the voltage deviation of individual cells to determine whether equalization processing is required.
Balancing : Perform active or passive balancing operations based on the analysis results.
Result verification : The voltage of each individual unit was confirmed to be consistent after remeasurement, and a maintenance report was generated.
This process can accurately reflect the health status of the battery pack and ensure the long-term reliable operation of the energy storage system.
Battery equalization detection method
Voltage sampling method : Real-time monitoring of individual cell voltage.
Internal resistance analysis method : Combine internal resistance measurement to judge the battery balancing effect.
Temperature monitoring method : Abnormal temperature can indicate uneven temperature distribution.
