For the capacity testing of battery packs for backup power systems, there are currently two main methods: Traditional capacity testing and remote online capacity testing.
Traditional capacity testing relies on manually connecting dummy loads to individually inspect and verify batteries at dispersed application sites. This method faces three main issues in practical operations.
Safety Concerns
Before capacity testing, operators need to disconnect the battery packs from the busbars to ensure offline status, which poses the risk of power outage accidents if unexpected power interruptions occur during this process. Moreover, disconnected battery packs require connection to dummy loads for discharge capacity testing, which generates considerable heat and fire hazards, as well as wastes energy, conflicting with sustainable development principles of carbon reduction.
Data Security Issues
Manual recording of capacity testing data inevitably leads to errors and omissions. Additionally, manually recorded raw data is relatively scattered with poor systematic organization, which hinders comprehensive analysis and comparison of the data afterwards.
Cost-Expenditure Issues
Capacity testing of battery packs needs to be conducted periodically across dispersed sites, particularly in large-scale installations with numerous battery packs. This necessitates substantial allocation of human and material resources during operational processes, posing significant financial pressure on long-term and sustainable maintenance.
Addressing the above issues associated with traditional methods, remote online capacity testing is equipped with specific functionalities to enhance the safety and efficiency of capacity testing operations.
Ensuring Operational Safety
Remote online capacity testing systems utilize real load discharge methods, avoiding the risks of unexpected shutdowns caused by offline loads and eliminating safety hazards associated with excessive heat release. This approach also promotes energy conservation and environmental protection, aligning with sustainable production concepts.
Achieving Data Security
The slope of discharge curves can reflect battery discharge performance. Flatter discharge curves typically indicate stable discharge characteristics, ensuring consistent energy output. Additionally, observing the plateau region of discharge curves reveals voltage changes under different discharge depths, enabling evaluation of battery discharge capabilities.
Reducing Operational Costs
By installing capacity testing devices at various battery application sites and using network communication, maintenance personnel can remotely conduct capacity testing via central station software, eliminating the need for on-site operations.
When designing remote capacity testing systems, besides focusing on core capacity testing functionalities, additional features such as online monitoring of battery packs and battery activation are included to provide more comprehensive and cost-effective solutions for backup power application scenarios. For instance, the DFUN remote online battery capacity testing system is designed with a focus on operational safety, usability, and reducing maintenance expenses. The system includes functions of battery activation and battery balancing, thereby extending battery lifespan and reducing customer maintenance efforts.
