METHOD AND DEVICE FOR MONITORING A STABLE CONVERGENCE BEHAVIOUR OF A KALMAN FILTER

摘要

Method for monitoring a stable convergence behavior of a Kalman filter (KF) which estimates states and / or parameters of an energy storage system, in particular a battery cell (BZ), wherein a covariance behavior provided by the Kalman filter (KF) with respect to at least one state and / or a parameter of the energy storage system is compared with a corresponding desired covariance behavior of the state and / or parameter, wherein the Kalman filter (KF) for each state and / or each parameter of the energy storage system whose covariance behavior exceeds the corresponding desired covariance behavior is automatically deactivated
