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.

Secondary battery management system

A method for monitoring a battery while the battery is connected to a load has been developed. The method includes measuring a first current level flowing through the battery to the load and a first voltage level of the battery at a first time, generating an estimated open cell voltage (OCV) of the battery at the first time based on the first current level, the first voltage level, and a predetermined model of the battery, identifying a first excitation level of the battery at the first time based on the first voltage level, the first current level and a cost optimization process, and identifying at least one of a state of charge (SoC) and state of health (SoH) of the battery using the estimated OCV only in response to the first excitation level being below a predetermined threshold.

Method and system for estimating battery open cell voltage, state of charge, and state of health during operation of the battery
