METHOD FOR ASSESSING AN ELECTRICAL STORAGE CELL

The invention relates to a method for assessing an electrical storage cell (2), comprising at least the following steps: * a) creating a reference data set (4) concerning the ageing behaviour of an individual reference storage cell (6) of a specific type with regard to the charging and discharging behaviour thereof, * b) creating a second reference data set (41) of a second reference storage cell (61) of the same type, * c) measuring an electrochemical operating characteristic (8, 8') of each reference storage cell (6, 6') for which a reference data set (4, 4') is created, and linking this operating characteristic (8, 8') to the reference data set (4, 4') thereof, * d) saving at least two reference data sets (4, 41) of at least two reference storage cells (6, 6') of the same type and the associated links to the operating characteristic (8, 8') in a database (10), * e) measuring the electrochemical operating characteristic (8") of a storage cell (2), and * f) comparing the measured operating characteristic (8") of the storage cell (2) with the operating characteristics (8, 8') of the reference storage cells (6, 6') saved in the database (10), and * g) assigning the storage cell (2) by means of an assignment key to one of the operating characteristics (8, 8') saved in the database (10) and the reference data set (4, 4') linked thereto.
