BATTERY MODULE, APPARATUS, AND FAILURE PROCESSING METHOD FOR FAILED BATTERY CELL

This application relates to a battery module, a device, and a failure handling method for a failed battery cell. The battery module includes: battery cells, including a housing, a top cover, and an electrode assembly, the housing is connected to the top cover, the battery cell includes a first accommodation cavity, the electrode assembly is located inside the first accommodation cavity, the top cover is provided with a positive electrode terminal and a negative electrode terminal, the positive electrode terminal and the negative electrode terminal are arranged along a length direction of the battery module, and face toward a width direction of the battery module, and the battery cells further include a failed battery cell; and a conductive component, connected to the positive electrode terminal and the negative electrode terminal of the failed battery cell, where along a height direction of the battery module, the housing includes a first cover plate and a second cover plate that are arranged opposite each other, both the first cover plate and the second cover plate are connected to the top cover, the first cover plate and/or the second cover plate is provided with an opening, and the conductive component is able to pass through the opening and reside inside the first accommodation cavity. After being connected to the electrode terminals, the conductive component does not occupy space outside the failed battery cell, improving safety of the battery module.
