Battery pack with fusible link

A battery pack for electrical equipment, the battery pack comprising:

• a battery cell;
• a terminal configured to electrically connect to the electrical equipment;
• and
• a fusible link plate electrically connecting the battery cell to the terminal and having a bent shape,
• wherein
• the fusible link plate comprises:
• a first plate part extending in a first direction;
• a second plate part extending in a second direction different from the first direction;
• and
• a bent part connecting the first plate part to the second plate part,
• the first plate part, the second plate part, and the bent part are disposed along a first plane that is along both the first direction and the second direction,
• the first plate part comprises a first thermal diffusion suppressing aperture penetrating the first plate part in a direction perpendicular to the first plane,
• the second plate part comprises a second thermal diffusion suppressing aperture penetrating the second plate part in the direction perpendicular to the first plane,
• first thermal diffusion suppressing parts are each disposed between the first thermal diffusion suppressing aperture and a first side surface of the first plate part and between the first thermal diffusion suppressing aperture and a second side surface of the first plate part,
• second thermal diffusion suppressing parts are each disposed between the second thermal diffusion suppressing aperture and a first side surface of the second plate part and between the second thermal diffusion suppressing aperture and a second side surface of the second plate part,
• each of the first thermal diffusion suppressing parts has a first cross-sectional area in a cross section of the first thermal diffusion suppressing part along a plane perpendicular to the first direction,
• each of the second thermal diffusion suppressing parts has a second cross-sectional area in a cross section of the second thermal diffusion suppressing part along a plane perpendicular to the second direction,
• the bent part comprises a first fusible part having a third cross-sectional area in a cross section of the bent part along a plane perpendicular to a direction along the first plane,
• the third cross-sectional area is smaller than the first cross-sectional area and smaller than the second cross-sectional area, and
• the first cross-sectional area is equal to the second cross-sectional area.
