Health feature extraction from battery energy storage system field fault data
Clement Wong, Andrew Weng, Xin Hui Ooi +6
Health monitoring methods are critical for lithium-ion battery modules connected to the grid to prevent faults that can lead to catastrophic events. However, assessing the health o…
Modeling and Estimation of Solid Electrolyte Interphase during Formation in Battery Manufacturing
Zhiwen Wan, Hamidreza Movahedi, Wenxue Liu +4
The solid electrolyte interphase (SEI) - a critical passivation layer that governs the longevity, safety, and efficiency of lithium-ion batteries - is created during the last step…
Differential Voltage Analysis and Patterns in Parallel-Connected Pairs of Imbalanced Cells
Clement Wong, Andrew Weng, Sravan Pannala +3
Diagnosing imbalances in capacity and resistance within parallel-connected cells in battery packs is critical for battery management and fault detection, but it is challenging give…
The Case for DeepSOH: Addressing Path Dependency for Remaining Useful Life
Hamidreza Movahedi, Andrew Weng, Sravan Pannala +2
The battery state of health (SOH) based on capacity fade and resistance increase is not sufficient for predicting Remaining Useful life (RUL). The electrochemical community blames…
