BATTERY MODULE, DEVICE, AND FAILURE TREATMENT METHOD FOR FAILED BATTERY CELL

A battery module (M), a pressing plate (D), and a failure handling method for a failed battery cell (133). The battery module (M) includes: a battery cell arrangement structure (1), including a plurality of battery cells (13) arranged along a length direction (X), where the battery cells (13) include electrode terminals (131) that are arranged along the length direction (X), and face toward a width direction (Y), and the battery cells (13) include a failed battery cell (133); a box body (5), having an accommodation cavity (51) in which the battery cell arrangement structure (1) is located; a mounting beam (52), located in the accommodation cavity (51) and at an end of the battery cell arrangement structure (1) along the width direction (Y); a pressing plate (4), where at least part of the pressing plate is located at an end of the battery cell arrangement structure (1) along a height direction (Z), and the pressing plate (4) is detachably connected to the mounting beam(52); and a conductive component (6), connected to a positive electrode terminal (131a) and a negative electrode terminal (131b) of the failed battery cell (133), and along the height direction (Z), at least part of the conductive component (6) is located between the mounting beam (52) and the pressing plate (4). The conductive component (6) is easily connected to electrode terminals (131) of a failed battery cell (13), so that a maintenance process can be simplified and maintenance costs can be reduced.
