Abstract
Device () and method for detecting battery cell states, BZZ, and/or battery cell parameters, BZP, of at least one battery cell (BZ), comprising a dual Kalman filter () which includes a state estimator (A) for estimating battery cell states, BZZ, and a parameter estimator (B) for estimating battery cell parameters, BZP, and comprising a determination unit () which is suitable for determining noise components (n, v) of the state estimator (A) and of the parameter estimator (B) on the basis of a stored characteristic parameter behaviour of the battery cell (BZ), wherein the battery cell states, BZZ, and the battery cell parameters, BZP, can be adapted automatically to a specified battery model (BM) of the battery cell (BZ) by means of the dual Kalman filter () on the basis of the noise components (n, v) determined by the determination unit.
