Secondary battery management system

Patent ·
OSTI ID:1600340
; ; ; ; ;

A method of managing a battery system, the method including receiving at least one measured characteristic of the at least one battery cell from the at least one sensor, estimating at least one state of the at least one battery cell at a first time by applying an electrochemical-based battery model, estimating at least one physical parameter of the at least one battery cell based on the at least one measured characteristic and the estimation of the at least one state, estimating the at least one state at a second time, subsequent to the first time, by applying the electrochemical-based battery model based on the estimated at least one parameter, and regulating at least one of charging or discharging of the at least one battery cell based on the estimation of the at least one state.
