Abstract

The invention relates to the technical field of batteries, and discloses a battery pack thermal runaway processing device and a battery pack thermal runaway processing method. The battery pack thermalrunaway processing device comprises: an exhaust pipeline arranged at an explosion-proof valve of a battery pack, wherein the exhaust pipeline can guide out harmful gas exhausted after the explosion-proof valve is opened when the battery pack is in thermal runaway; and a first purification unit arranged on the exhaust pipeline, wherein the first purification unit is arranged to be capable of removing hydrofluoric acid in the harmful gas. The battery pack thermal runaway processing device can remove hydrofluoric acid in harmful gas generated by thermal runaway of the battery pack.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a battery pack thermal runaway processing device and a battery pack thermal runaway processing method. Background technique [0002] The contemporary automobile industry is undergoing revolutionary changes, that is, traditional fuel vehicles are gradually being replaced by new energy vehicles. Among them, pure electric vehicles have gained a lot of favor as a type of new energy vehicles, and battery packs have been favored as the main components of electric vehicles. More and more research. After the thermal runaway of the power battery pack, it will emit gas containing harmful substances such as hydrofluoric acid. If the gas containing harmful substances is directly discharged, it will cause air pollution. Contents of the invention [0003] The object of the present invention is to provide a battery pack thermal runaway processing device, which can remove hydrofluoric acid ...
