The 3σ multi-level screening strategy was utilized to build the criteria for normal operating cell voltage, and a neural network was applied to simulate the cell fault distribution in a battery pack. This method requires an extended period to collect battery data to detect battery faults reliably.
Maintenance and troubleshooting for Battery Management Systems (BMS) require a holistic approach to ensure the reliability and longevity of energy storage systems. Regular inspections and testing are foundational elements, allowing for the identification of potential issues before they escalate.
Battery-powered equipment running on Li-ion cells certainly retains its performance much longer compared to the NiMH cell-based power tools of the past. However, after many charge/discharge cycles, there comes a time when the energy storage capacity of even the best lithium battery drops so low that the battery pack needs to be replaced.
A schematic of fault diagnosis in the battery management system (BMS). In the battery system, the BMS plays a significant role in fault diagnosis because it houses all diagnostic subsystems and algorithms.
There has not been an effective and practical solution to detect and isolate all potential faults in the Li-ion battery system. There are several challenges in Li-ion battery fault diagnosis, including assumption-free fault isolation, fault threshold selection, fault simulation tools development, and BMS hardware limitations.
Out-of-balance cells reduce the overall usable capacity of the battery and can lead to both premature cell aging as well as overcharge or undercharge damage. An effective BMS must have precise monitoring and cell balancing capabilities to measure voltage differences and keep cells locked in at the proper levels.
