Abstract

A method includes controlling operation of a vehicle in response to an estimation of a capacity loss and capacity of a lithium-ion battery module of the vehicle. The estimation is a function that includes a state-of-lithiation swing and fracture of a solid-electrolyte interphase of an electrode of the lithium-ion battery module. The methodology can be implemented in a vehicle that includes a lithium-ion battery module and a controller that controls operation of the vehicle in response to such an estimation.
