A vehicle battery system includes a traction battery. The traction battery includes at least one cell having an anode, a cathode and an electrolyte therebetween defining a solid-electrolyte interface including an anode solid-electrolyte interface and a cathode solid-electrolyte interface. The system also includes at least one controller that operates the traction battery according to a battery operational variable that is based on a temperature dependent diffusion coefficient of the solid-electrolyte interface, a temperature dependent Ohmic resistance, a Li-ion concentration that is derived from a response to a current profile, and an operating battery current.
