Claim One:
1. A battery management system for an electrified powertrain of a hybrid vehicle, the system comprising: one or more sensors configured to measure voltage, current, and temperature for a battery system of the hybrid vehicle; and a controller configured to: obtain an equivalent circuit model for the battery system; determine a set of states for the battery system to be estimated; determine a set of parameters for the battery system to be estimated; receive, from the one or more sensors, the measured voltage, current, and temperature for the battery system; and using fp the equivalent circuit model, (ii) the measured voltage, current, and temperature of the battery system, and (iii) a mixed sigma-point Kalman filtering (SPKF) and recursive least squares (RLS) technique to estimate the sets of states and parameters for the battery system; and using the sets of estimated states and parameters for the battery, system to control an electric motor of the electrified powertrain.
