WebDec 14, 2024 · The accurate state of health (SOH) estimation of lithium-ion batteries enables users to make wise replacement decision and reduce economic losses. SOH estimation accuracy is related to many factors, such as usage time, ambient temperature, charge and discharge rate, etc. Thus, proper extraction of features from the above factors … WebThe economic viability of reusing lithium-ion batteries obtained from electric vehicles is highly sensitive to increasing inner resistance and capacity fading of lithium-ion cells. For decision making after removal of the batteries, it is necessary to consider the uncertainties in prediction of the remaining battery lifetime.
