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…
