BATTERY PACK
Document Type and Number:
Japanese Patent JP2023005159
Kind Code:
A
Abstract:
To disclose a technology capable of further downsizing a battery pack equipped with a fuse link plate blown out when overcurrent flows.SOLUTION: A battery pack is equipped with a fuse link plate having a bent shape. The fuse link plate is equipped with a first flat plate portion extending in a first direction, a second flat plate portion extending in a second direction, and a bending portion that connects the first flat plate portion and the second flat plate portion. The first flat plate portion, the second flat plate portion, and the bending portion are disposed along a first plane along the first direction and the second direction. The first flat plate portion is equipped with a part having a first cross-sectional are when cut by a plane orthogonal to the first direction. The second flat plate portion is equipped with a part having a second cross-sectional are when cut by a plane orthogonal to the second direction. The bending portion is equipped with a first blown-out portion having a third cross-sectional area when cut by a plane orthogonal to a direction along the first plane. The third cross-sectional area is smaller than the first cross-sectional area, and is smaller than the second cross-sectional area.SELECTED DRAWING: Figure 7
