Document Type and Number:
WIPO Patent Application WO/2023/284886
Kind Code:
A1
Abstract:
The present application provides a battery pack, comprising: a battery cell body, a housing, a heat sink, and an upper cover. The housing surrounds a part of the surface of the battery cell body. The heat sink is disposed on the housing. The bottom surface of the heat sink abuts against a bus board disposed on the upper end of the battery cell body. The heat sink is in thermal contact with a module electrode at the upper end of the battery cell body. The upper cover is disposed on the heat sink. In the battery pack provided by the present application, heat dissipation around the battery cell body can be achieved, and heat generated by a tab or heat conducted by the battery cell body to the tab can be guided outwards. Thus, all-round heat dissipation around the battery pack can be achieved. The battery pack is suitable for unmanned aerial vehicles, and meets high usage requirements for unmanned aerial vehicle heat dissipation.
