Abstract (en)
[origin: WO2020191419A1] A battery module is described with a main part (1) for receiving individual battery cells (4) arranged in parallel with respect to a joining axis (2), which main part forms a flow channel (6), extending transversely to the joining axis (2), for a temperature-control fluid flowing directly against the cell shells of the battery cells (4). In order not only to reduce the risk of thermal damage to individual battery cells (4) during peak loads, but also to prevent the spread of a chain reaction in the event of a thermal runaway failure, according to the invention, for each battery cell (4), a burst protection sleeve (7, 8) which surrounds the battery cell (4) circumferentially with a clearance, forming an air gap (10), is mounted upstream and downstream of the flow channel (6) in the direction of the joining axis (2), the flow channel (6) extending over a height of 28 - 60% of the battery cell (4) and each burst protection sleeve (7, 8) extending over a height of 20 - 36% of the battery cell (4).
