Abstract

The invention discloses a battery tray and a battery pack assembly with the same. The battery tray comprises a tray body and a heat management part, wherein the heat management part comprises a heat pipe and a cold pipe which are connected with each other; the cold pipe is connected to the end of the heat pipe; and the cold pipe is located between the heat pipe and the inner side wall of the traybody, or the heat pipe is located between the cold pipe and the tray body. The battery tray provided by the embodiment of the invention is light in weight, high in strength, compact in arrangement andconvenient to maintain.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular, to a battery tray and a battery pack assembly having the same. Background technique [0002] In related technologies, improving the energy density of batteries is an important means of optimizing power batteries. There are two conventional methods for improving the energy density of batteries: one is to use materials with higher energy density; the other is to use materials with higher energy density. The improvement of the battery structure enables the same battery module to obtain higher energy density. Among them, the method usually used to improve the battery structure is light weight and compactness, especially the light weight effect is the best, usually by reducing or removing part of the structural parts, or reducing the thickness of the material. Although the above methods can reduce the weight of the battery pack, However, the strength of the battery pack will also be r...
