Embodiment

[0030] The battery box is the bearing and protection mechanism of the battery module. Multiple battery modules are installed on the battery tray in the battery box. The battery module is composed of multiple batteries connected in series or in parallel. A liquid cooling plate assembly for maintaining the temperature inside the battery pack is also provided. Such as Figure 1-6 As shown, the liquid-cooled battery tray in the embodiment of the present application includes a tray frame 1 and a liquid-cooled plate assembly 2. The tray frame 1 is provided with a module installation surface 7 for cooperating with the battery module 9, and the battery module 9 passes through the mold. The group mounting surface 7 is fixed on the tray frame 1; the liquid cooling plate assembly 2 includes a liquid cooling plate 21 and a protective plate 22; the liquid cooling plate 21 is fixed under the tray frame 1, and the liquid cooling plate 21 is in contact with the bottom of the battery module 9 ...

Abstract

The invention relates to a liquid-cooled battery tray and a battery box, the liquid-cooled battery tray comprises a tray frame and a liquid-cooled plate assembly, the tray frame is provided with a module installation surface used for cooperatively installing a battery module, and the battery module is fixed on the tray frame through the module installation surface; the liquid cooling plate assembly comprises a liquid cooling plate and a protection plate, the liquid cooling plate is fixed below the tray frame, and the liquid cooling plate is in contact with the bottom of the battery module; and the protection plate is arranged below the liquid cooling plate. The battery tray disclosed by the invention has the advantages of light weight, high structural strength, good load bearing and better cooling effect.

Description

technical field [0001] The invention relates to the technical field of power batteries, in particular to a liquid-cooled battery tray and a battery box. Background technique [0002] In recent years, electric vehicles have gradually replaced fuel vehicles and achieved rapid development. Among them, driving range and safety issues have always been the key factors restricting the development of electric vehicles. The battery pack box is used as the load-bearing part of the battery pack system. It directly affects the energy density and life of the battery pack. In the prior art, the battery pack box includes a tray, a tray bottom and a liquid cooling plate. The tray bottom is usually used to support and fix the battery. The cold plate is arranged under the bottom plate, and the excess heat generated by the battery operation is transferred to the liquid cold plate through the bottom plate, relying on the liquid flow in the liquid cold plate to transfer cooling, which is not on...
