Abstract

The invention provides a battery thermal runaway gas discharge device, a battery module and an automobile, so as to reduce the influence of the battery thermal runaway on adjacent battery cells. The battery thermal runaway gas discharge device includes: a flow guide structure, with a flow guide channel in the flow guide structure; used to divert the thermal runaway gas generated during the thermal runaway of the battery cell and guide it to the flow guide channel The inner shunt structure; the shunt structure partially passes through the outer wall of the shunt structure and extends into the shunt channel.

Description

[0001] Technical field [0002] The invention belongs to the field of auto parts, and in particular relates to a battery heat runaway gas discharge device, a battery module and an automobile. Background technique [0003] With the rapid development of the new energy vehicle industry, battery thermal runaway is the most serious form of failure, and battery thermal safety has become a bottleneck restricting the development of electric vehicles. At present, the modules are placed adjacent to each other. In order to improve the integration efficiency, the gap between the modules is very small. This arrangement is very prone to heat dissipation. The heat diffusion between adjacent battery modules is mainly due to the heat convection of "cell-air-cell" and the heat conduction of "cell-box-cell", and the contribution of heat convection to heat diffusion is greater than that of heat conduction. As far as the layout of the existing battery pack modules is concerned, when a cell underg...
