BATTERY MODULE, BATTERY PACK, AND APPARATUS

This application relates to the technical field of energy storage devices, and in particular, to a device (D), a battery pack (M), and a battery module (A). The battery module (A) includes a battery cell (1) and an insulation board (2). The insulation board (2) includes a body portion (21) and a first bulge (22). The first bulge (22) includes a sidewall (221) and a top wall (222) that close in to form an accommodation cavity. At least a part of an electrode terminal (11) is accommodated in the accommodation cavity, and the top wall (222) covers a part of the electrode terminal (11), thereby reducing a risk of letting metal particles or other impurities enter a position between the battery cells (1), where the metal particles are generated during welding. This reduces difficulty of cleaning the battery module, and improves safety and reliability of the battery module (A).
