Problems solved by technology

[0002] At present, the energy density of the battery cell in the battery module on the vehicle is getting higher and higher, and the energy of the battery cell is getting larger and larger. Airflow blows away) the risk increases
However, the current battery modules do not have the function of detecting and controlling the thermal pressure and thermal runaway of the battery cells in the battery module, so as the energy of the battery cells continues to increase, the harm of the thermal runaway of the battery cells continues to increase.

Abstract

The invention discloses a battery module and a vehicle with the same. The battery module comprises a battery cell which is provided with a battery cell end part; a rupture disk arranged at the batterycell end part; a heat insulation plate arranged on one side, deviating from the battery cell, of the rupture disk, wherein a pressure relief channel is formed between the rupture disk and the heat insulation plate; and a thermal runaway detection element used for detecting a thermal runaway signal in the pressure relief channel. According to the invention, the rupture disk is arranged at the battery cell end part of the battery cell; when thermal runaway occurs in the battery cell, the high-temperature and high-pressure thermal runaway air flow breaks through the rupture disk, enters the pressure relief channel and is discharged to the outside of the battery module through the pressure relief channel; and in the process, the thermal runaway air flow will pass through the thermal runaway detection element and the thermal runaway detection element can detect a thermal runaway signal, so that safety control measures are taken on the battery cell. In addition, the pressure relief channelcan enable the thermal runaway air flow to be discharged out of the battery module along a specific path, so that the influence of the thermal runaway air flow on other battery cells is reduced.

Description

technical field [0001] The present invention relates to the technical field of vehicle batteries, in particular, to a battery module and a vehicle having the same. Background technique [0002] At present, the energy density of the battery cell in the battery module on the vehicle is getting higher and higher, and the energy of the battery cell is getting larger and larger. blown away by the airflow) the risk increases. However, the current battery modules do not have the function of detecting and controlling the thermal pressure and thermal runaway of the battery cells in the battery module. As the energy of the battery cells continues to increase, the harm of the thermal runaway of the battery cells continues to increase. . Contents of the invention [0003] The present invention aims to solve one of the above-mentioned technical problems in the prior art at least to a certain extent. For this reason, the present invention proposes a battery module, which can discharg...
