Document Type and Number:
WIPO Patent Application WO/2024/056034
Kind Code:
A1
Abstract:
The present application provides a battery pack and a mower. The battery pack comprises: a casing; a plurality of battery modules, the plurality of battery modules being provided in the casing at intervals; a cooling air duct formed between the plurality of battery modules provided at intervals and the casing; an air inlet assembly and an air outlet assembly, provided on the casing corresponding to the head end and the tail end of the cooling air duct, so that external air flows into the casing from an inlet of the air inlet assembly and flows out of the casing from an outlet of the air outlet assembly; and a cooling assembly provided on at least part of a path between the inlet of the air inlet assembly and the casing through which air flows, wherein the air flowing in through the inlet of the air inlet assembly is in contact with the cooling assembly. The present application realizes the overall cooling for the battery modules, improves the cooling effect and the cooling efficiency, solves the problem of thermal runaway caused by the inability to achieve a heat dissipation effect due to the fact that some of the battery cells are not cooled significantly, effectively saves the space and reduces the cost, improves a working environment of the battery pack, and effectively avoids foreign matter suction and realizes a water splashing prevention function.
