Abstract
The invention relates to a battery module having with a main body () for accommodating individual battery cells () arranged in parallel with respect to a joining axis (), which main body forms a flow channel () extending transversely to the joining axis () for a temperature-control fluid flowing directly against the cell shells of the battery cells (). In order not only to reduce the risk of thermal damage to individual battery cells () during peak loads, but also to prevent the propagation of a chain reaction in the event of a thermal runaway fault, it is proposed that, for each battery cell (), a burst protection sleeve (), which surrounds the battery cell () circumferentially with a clearance by forming an air gap (), is mounted upstream and downstream of the flow channel () in the direction of the joining axis (), wherein the flow channel () extends over a height of 28-60% of the battery cell () and each burst protection sleeve () extends separately over a height of 20-36% of the battery cell ().
