Abstract

The invention provides a lithium ion battery photo frame filled with a phase change material. The photo frame comprises a photo frame body forming a photo frame module; a battery cell cavity for arranging a battery cell and a phase-change material filling cavity for filling the phase-change material are arranged in the photo frame body; the phase-change material filling cavity is arranged outsidethe battery cell cavity in a surrounding manner to cool the battery cell in the battery cell cavity; the phase-change material filling cavity is provided with an exhaust hole which is communicated with the outside and is used for balancing internal and external pressure, an acting surface, welded to a battery cell tab, of the photo frame body is arranged in an opening manner, and an aluminum sheetis arranged between the phase-change material filling cavity and the battery cell cavity of a symmetric acting surface with the maximum area of the photo frame body. According to the invention, the space of the battery and the whole vehicle is saved, the thermal resistance in the heat conduction process can be reduced, the consistency of the temperature of the battery is effectively improved, thesystem temperature difference is reduced, the thermal management performance is improved, the service life of the battery is prolonged, the battery electric quantity is saved, and safety and reliability are realized.

Description

technical field [0001] The invention relates to the field of lithium ion battery photo frames, in particular to a lithium ion battery photo frame filled with phase change materials. Background technique [0002] The current lithium-ion battery thermal management system adopts solutions including water cooling, air cooling, direct cooling, etc., but these solutions are all at the cost of consuming battery power to cool down the battery cell, which not only reduces the mileage, and the system is complex, the cooling system takes up a lot of space in the battery system or the vehicle; at the same time, the structure of the existing battery photo frame is complex, and there are many electrical components and mechanical connections in the thermal management system, so the lithium-ion battery photo frame There is a high potential failure rate when installing cooling systems. Contents of the invention [0003] Aiming at the defects in the prior art, the object of the present inv...
