Battery tray, battery pack and vehicle

Abstract

The invention relates to the technical field of batteries, in particular to a battery tray, a battery pack and a vehicle. The battery tray comprises a tray body and a heat preservation layer. The upper end face of the tray body is used for bearing a battery module, the lower bottom face of the tray body comprises a mounting area and a heat preservation area, the tray body is fixedly arranged through the mounting area, and the heat preservation area is provided with a plurality of clamping structures. The heat preservation layer is connected with the clamping structure in a clamped mode so that the heat preservation layer and the tray body can be connected into a whole, the connection strength of the heat preservation layer and the tray body is improved, and therefore the heat preservation effect of the battery tray is improved. The battery pack comprises the battery tray, so that the heat preservation effect of the battery pack is improved, the corrosion of the external environment to the battery pack is reduced, and the reliability of the battery pack is improved. The vehicle comprises the battery pack, the heat preservation layer is located on the lower bottom face of the supporting plate body, so that the battery pack has the bottom armor function, meanwhile, the heat preservation layer can absorb part of collision vibration, and the NVH characteristic of the vehicle is improved.

Description

technical field [0001] The invention belongs to the technical field of batteries, and in particular relates to a battery tray, a battery pack and a vehicle. Background technique [0002] With the rapid development of new energy vehicles, it is necessary to control the temperature of the lithium-ion power battery used in the vehicle to avoid the impact of the battery from the external high temperature or low temperature environment, so as to ensure the safe and stable operation of the battery [0003] At present, the main method of heat insulation and heat preservation of the battery box is: spraying or bonding the heat insulating layer on the box wall of the battery box. The thickness of the sprayed heat insulation layer is difficult to accurately control, the heat insulation layer that is too thick is prone to cracking or falling off, and the heat insulation layer that is too thin has poor thermal insulation effect. The glue that holds the insulation together fails over ti...

AI Technical Summary

Problems solved by technology

It is difficult to accurately control the thickness of the thermal insulation layer sprayed, too thick thermal insulation layer is prone to cracking or falling off, and too thin thermal insulation layer has poor thermal insulation effect

The glue that holds the insulation together fails over time, causing the insulation to fall off

[0004] The connection strength between the existing heat insulation layer and the battery box is poor, the reliability is low, and it is difficult to ensure a good heat preservation effect
