Abstract
A battery cell performance monitoring system includes an energy storage system that includes at least one inverter and battery nodes. Each of the battery nodes includes battery racks, and each of the battery racks includes battery cells. The battery cell performance monitoring system also includes a processor, memory, and programming in the memory. The programming causes the battery cell performance monitoring system to determine an extreme rack cell voltage value of each battery rack. Next, to determine an average extreme rack cell voltage value based on the extreme rack cell voltage value of each battery rack. Further, to compare an extreme rack cell voltage value for each battery rack with the average extreme rack cell voltage value. Additionally, to identify one or more outlier battery racks based upon the comparison of the extreme rack cell voltage value for each battery rack with the average extreme rack cell voltage value.
