技术领域Technical Field
本发明涉及动力电池技术领域，尤其是涉及一种电池箱体、电池包和电动车。The present invention relates to the technical field of power batteries, and in particular to a battery box, a battery pack and an electric vehicle.
背景技术Background Art
随着当前社会能源危机日益严重，新能源汽车越来越受到社会关注，尤其是电动汽车。电池模组作为电动汽车上的主要储能元件，是电动汽车的关键部件。As the current social energy crisis becomes increasingly serious, new energy vehicles are receiving more and more attention from the society, especially electric vehicles. As the main energy storage component of electric vehicles, battery modules are the key components of electric vehicles.
图1和图2所示为一种目前常规的电池包结构，该结构中，电池模组2布置在托盘1内部，通常在托盘1侧壁111和112外侧会布置1个或多个防爆透气阀3。但采用上述结构还存在以下缺陷：当发生热失控后，电池包内急剧产生大量的高温有害气体，当压力达到防爆透气阀开启压力后，阀将开启，气体从阀排出；由于防爆透气阀是布置在外侧，气体会从电池包侧面喷发出来，有概率喷射到人身上引起伤害，存在安全隐患。Figures 1 and 2 show a conventional battery pack structure, in which the battery module 2 is arranged inside the tray 1, and one or more explosion-proof vent valves 3 are usually arranged outside the side walls 111 and 112 of the tray 1. However, the above structure still has the following defects: when thermal runaway occurs, a large amount of high-temperature harmful gas is rapidly generated in the battery pack. When the pressure reaches the opening pressure of the explosion-proof vent valve, the valve will open and the gas will be discharged from the valve; since the explosion-proof vent valve is arranged on the outside, the gas will spray out from the side of the battery pack, and there is a probability that it will spray onto people and cause injuries, posing a safety hazard.
发明内容Summary of the invention
本发明的目的就是为了克服上述现有技术存在的缺陷而提供一种安全性高的电池箱体、电池包和电动车。The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide a battery box, a battery pack and an electric vehicle with high safety.
本发明的目的可以通过以下技术方案来实现：The purpose of the present invention can be achieved by the following technical solutions:
第一方面，本发明提供一种电池箱体，包括用于放置电池模组的托盘，所述托盘包括托盘底部和在所述托盘底部围设形成放置电池模组区域的四个侧壁，至少一个所述侧壁为带有空腔的结构，该结构的内侧面上安装有至少一个防爆透气阀，所述托盘底部开设有至少一个与所述空腔连通的第一通孔。In a first aspect, the present invention provides a battery box, comprising a tray for placing a battery module, the tray comprising a tray bottom and four side walls arranged on the tray bottom to form an area for placing the battery module, at least one of the side walls is a structure with a cavity, at least one explosion-proof air valve is installed on the inner side surface of the structure, and at least one first through hole connected to the cavity is opened at the tray bottom.

When a large amount of gas is generated due to thermal runaway of the battery cell, the pressure in the inner cavity of the battery box increases to the opening pressure of the explosion-proof vent valve, and the gas passes through the explosion-proof vent valve into the cavity and is discharged from the first through hole through the cavity, thereby changing the injection direction of the gas. Since the hole is at the bottom of the battery box, the gas is discharged to the ground, so that the harmful gas emission generated by the thermal runaway of the battery cell reduces the harm to people, and the safety is high.
