METHOD FOR DETECTING A SELF-DISCHARGE DEFECT IN A BATTERY CELL
Said method is used for detecting, in an electric storage battery (10) having a plurality of battery cells (1, 2, 3, 4), a self-discharge defect in a cell (1, 2, 3, 4), wherein: a charge balancing of the battery cells (1, 2, 3, 4) is at least partially carried out, a relaxation of the battery cells...

Summary: | Said method is used for detecting, in an electric storage battery (10) having a plurality of battery cells (1, 2, 3, 4), a self-discharge defect in a cell (1, 2, 3, 4), wherein: a charge balancing of the battery cells (1, 2, 3, 4) is at least partially carried out, a relaxation of the battery cells (1, 2, 3, 4) is performed, a charge balance during the balancing and relaxation (Σi) of said cell (i) is calculated for each battery cell (i), and any self-discharge defects of said cell (i) are detected for each battery cell (i) depending on the charge balance calculated for said cell (i) during the balancing and relaxation (Σi). |
