Abstract: This application relates to the field of energy storage devices, and in particular, to a battery module, the battery module including a battery cell; a housing that includes an inner cavity for accommodating the battery cell; an output assembly arranged at an exterior side of the housing and electrically connected to the battery cell; and a module upper cover that seals the inner cavity. The module upper cover includes a body and an extension connected to the output assembly. This application resolves the technical problem that a module upper cover may easily get warped at an output electrode.
