A battery energy storage system (100) has at least two battery modules (10), each having a plurality of electrochemical energy storage cells, and optionally a base part (50) and/or a cover part (60). Each battery module (10) has at least one outer contact device (11, 12) for connecting to a further battery module (10) of the battery energy store system and/or optionally to a base part (50) and/or a cover part (60) of the battery energy store system. The contact device (11, 12) comprises at least one, preferably a plurality of connections for power and/or data signals. Adjacent battery modules (10) within the battery energy storage system (100) are electrically connected to one another by means of contact devices (11, 12). The battery energy store system is characterized in that the contact devices (11, 12) are each surrounded by a circumferential mechanical guide (14), and in the region of the contact devices (11, 12), within the circumferential mechanical guide (14), at least one gas passage opening (13) is
