MONITORING A CHARGE DISTRIBUTION AND/OR A CELL STATE OF A PLURALITY OF GALVANIC CELLS ELECTRICALLY CONNECTED IN SERIES

摘要

The invention relates to a method for monitoring a charge distribution and/or a cell state of a plurality of galvanic cells (34 to 44) electrically connected in series, comprising the following steps: generating reference data on the basis of a charging curve of a charging process before use of the galvanic cells (34 to 44) connected in series in intended operation, capturing charging data of a charging curve of a charging process after a start-up of the galvanic cells (34 to 44) connected in series, determining a first change curve (64) from the reference data, determining a second change curve (66) from the charging data, comparing the second change curve (66) with the first change curve (64) and generating a comparison result, determining the charge distribution and/or the cell state on the basis of the comparison result, and outputting a monitoring signal concerning the charge distribution and/or the cell state in accordance with the determined charge distribution and/or the cell state.
