Data-driven capacity estimation of commercial lithium-ion batteries from voltage relaxation

Data-driven capacity estimation of commercial lithium-ion batteries from voltage relaxation Abstract Accurate capacity estimation is crucial for the reliable and safe operation of lithium-ion batteries. In particular, exploiting the relaxation voltage curve features could enable battery capacity estimation without additional cycling information. Here, we report the study of three datasets comprising 130 commercial lithium-ion cells cycled under various conditions to evaluate the capacity estima...
