Title:
BATTERY PACK AND ELECTRICAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/055240
Kind Code:
A1
Abstract:
The present application discloses a battery pack and an electrical device. The battery pack comprises: a box body, having an accommodating space provided therein; a beam body, provided in the accommodating space to divide the accommodating space into a plurality of accommodating sub-cavities; a liquid cooling plate, attached to one side of the beam body facing the accommodating sub-cavity, the liquid cooling plate being welded to the beam body, and a welding seam being formed at the welding position; an insulating layer, attached to one side of the liquid cooling plate facing the accommodating sub-cavity, and at least covering the welding seam; and a plurality of battery cells, provided in the accommodating sub-cavities, and connected to the insulating layer and the liquid cooling plate, so as to perform heat exchange with the liquid cooling plate. Compared with the prior art, in the present application, the liquid cooling plate and the insulating layer are sequentially arranged on the beam body, and the insulating layer shields the welding seam on the liquid cooling plate, thereby avoiding a short circuit of the battery due to the fact that burrs at the welding seam pierce insulating films wrapped around the battery cells, and realizing insulation protection between the welding seam and the battery cells.
