Abstract

The invention relates to a battery module assembly method, comprising: providing K battery cells (110), K being a first integer; calculating a respective voltage drop (VD) of the K battery cells (110) due to a respective self-discharge of each of the multiple battery cells (110); selecting N battery cells (110) from the K battery cells (110), N being a second integer smaller than the first integer K; determining an extreme battery cell from the N battery cells (110) that exhibits a maximum voltage drop from the voltage drops (VD), or that exhibits a minimum voltage drop from the voltage drops (VD); calculating a summary statistic (M) as function of the voltage drops of the N battery cells (110) except for the extreme battery cell; calculating an A-value (A) of the N battery cells as function of the calculated summary statistic (M) and the voltage drop (VD) of the extreme battery cell; and if the A-value (A) is larger than a preset threshold (A<T>), removing the extreme battery cell from the N battery cells (110) and adding an alternative battery cell from the K battery cells (110) such that the N battery cells comprise the alternative battery cell and the N battery cells except for the extreme battery cell, wherein a second A-value (Λ) as calculated as function of the measure (M) and the voltage drop (VD) of the alternative battery cell is smaller than the preset threshold (A<T>). The invention further relates to a battery module (100).
