METHOD FOR CONNECTING MULTIPLE DIFFERENTLY DESIGNED BATTERY CELLS OF A BATTERY AND BATTERY SYSTEM COMPRISING A BATTERY WITH MULTIPLE DIFFERENTLY DESIGNED BATTERY CELLS

摘要

The present invention relates to a method of connecting a plurality of battery cells (24, 27) of a battery (111). The plurality of battery cells 24 and 27 may be connected in series and each battery cell is electrically connected to the battery 111 at a corresponding first probability P1i, And is electrically isolated from the battery 111 with probability P2i. The plurality of battery cells 24 and 27 form one group of battery cells 24 and 27 and the groups may include a first subgroup 114 of battery cells 24 designed to be identical to each other and / And a second subgroup 117 of battery cells 27 that are designed to be identical to one another and that are designed differently from the battery cells 24 of the first subgroup 114. Also for each battery cell 24 of the first subgroup 114 a quality factor G1i as a first function that depends on the current value of the battery current flowing through the battery 111 is calculated and / Or the battery cell 27 of the second subgroup 117, a quality factor G2i as a second function, which is dependent on the current value of the battery current and different from the first function, is calculated. For each battery cell 24 of the first subgroup 114 and / or for each battery cell 27 of the second subgroup 117, a corresponding first probability P1i and a corresponding 2 probabilities P2i are determined according to the calculated quality factors G1i and G2i of the corresponding battery cells 24 and 27, respectively.
