Abstract
Methods and systems for estimating values descriptive of a battery's present operating condition, comprising: estimating state-of-charge in a battery where said state-of-charge is comprised one of the internal states; and estimating state-of-health in a battery where said state-of-health is comprised one of the internal parameters. In particular, methods for estimating state-of-charge in a battery, comprising: making an internal states prediction of said battery where said state-of-charge is one of said internal states; making an uncertainty prediction of said internal states prediction; correcting said internal states prediction and said uncertainty prediction; and applying an algorithm that iterates said making an internal states prediction, said making an uncertainty prediction and said correcting to yield an ongoing estimation to said state-of-charge and an ongoing uncertainty to said state-of-charge estimation. And methods and systems for estimating present parameters of an electrochemical cell system comprising: making an internal parameter prediction of the cell; making an uncertainty prediction of the internal parameter prediction; correcting the internal parameter prediction and the uncertainty prediction; and applying an algorithm that iterates the internal parameter prediction, and the uncertainty prediction and the correction to yield an ongoing estimation to the parameters and an ongoing uncertainty to the parameters estimation.
