Embodiment Construction

[0032] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0033] In the present disclosure, unless stated otherwise, the used orientation words such as "up and down" are usually defined in the drawing direction of the drawings, specifically, refer to figure 1 , taking the opening direction of the battery tray as upward, and the opposite direction away from the opening direction as downward. "Inside and outside" refers to the inside and outside of the relevant parts. In addition, terms such as "first", "second" and the like are used to distinguish one element from another, and do not have order or importance.

[0034] like Figure 1 to Figure 8 As shown, the present disclosure provides a battery tray and a battery...

Abstract

The invention relates to a battery pack, a battery tray thereof and a vehicle. The battery tray comprises a tray bottom plate and edge beams arranged on the periphery of the tray bottom plate; the height of the upper surface of the tray bottom plate is gradually reduced from the center to the edge, and flow guide holes are formed in the edge beams and used for guiding flow of cooling liquid or condensate water flowing to the tray bottom plate. The battery tray can effectively avoid the risks of electric leakage, even short circuit, fire, explosion and the like caused by liquid leakage of the liquid cooling structure of the battery.

Description

technical field [0001] The present disclosure relates to the field of vehicle power batteries, and in particular, to a battery pack and its battery tray, and a vehicle. Background technique [0002] On the power battery of electric vehicles in the related technology, liquid cooling tubes are installed inside the battery pack, and the liquid cooling system is usually integrated with the battery tray. The liquid cooling system can be used under high temperature or long-term charging and discharging conditions Provide cooling for the battery system to ensure the normal use of the battery. However, in the power battery of the related technology, when the liquid cooling tube on the upper layer of the battery tray breaks and leaks, the cooling liquid will fill the entire battery pack, causing the battery pack to leak electricity or even short-circuit to catch fire and explode. Contents of the invention [0003] The purpose of the present disclosure is to provide a battery pack,...
