BATTERY MODULE, BATTERY PACK, DEVICE, AND FAILURE PROCESSING METHOD

Embodiments of the present application relate to a battery module, a battery pack, a device and a failure processing method. The battery module includes: a plurality of battery units for series connection, where after the battery module fails, the plurality of battery units include a failed battery unit and at least one unfailed battery unit adjacent to the failed battery unit; a connecting sheet, used to connect the plurality of battery units in series, where the connecting sheet is provided with at least one breakage guide portion for guiding the connecting sheet to break and form a first part and a second part which are arranged separately, where the first part is used to be connected to the at least one unfailed battery unit and the second part is used to be connected to the failed battery unit; and an electroconductive part, used to be connected to the first part, so that current bypasses the failed battery unit and the battery module resumes work. In the embodiments of the present application, the connecting sheet is provided with the breakage guide portion, so that the connecting sheet is easier to break, thereby the unfailed battery unit can be conveniently disconnected from the failed battery unit, and the failure processing efficiency is improved.
