Beschreibung
Zusammenfassung:	A battery module comprising a plurality of battery cell units (1), each one comprising: a battery cell (2) having a first pole (3) and a second pole (4), and a switch circuit (5), comprising a plurality of switches (8, 11, 12), and a switch controller (14) arranged to control the switches (8, 11, 12) of the switch circuit (5) to enter either of a first state, in which the battery cell (2) is connected in parallel with a neighboring battery cell, and a second state, in which the battery cell (2) is connected in series with a neighboring battery cell. The battery module is configured to control the switching between the first and second states on a probabilistic basis.
