Problems solved by technology

At present, in order to prevent flames from being ejected from the battery pack when the battery pack is thermally out of control, an explosion-proof valve is usually installed on the battery pack shell. However, due to the poor fire filtering performance of the existing explosion-proof valve, it cannot meet the high-intensity thermal runaway requirements of the battery pack.

Abstract

The invention discloses a fire filtering structure for a battery pack.The fire filtering structure is arranged on the inner wall of a shell of the battery pack and corresponds to an anti-explosion valve on the shell, the fire filtering structure is provided with a fire filtering face arranged on one side of the anti-explosion valve in a blocking mode and a mounting face located on the edge of the fire filtering face, a height difference exists between the fire filtering face and the mounting face, and a communicating port for communicating the interior of the shell with the anti-explosion valve is formed in the side part of the fire filtering structure. According to the fire filtering structure for the battery pack, the fire filtering performance of the battery pack can be improved by arranging the fire filtering surface, so that the safety performance of the battery pack can be improved.

Description

technical field [0001] The invention relates to the technical field of battery packs, in particular to a fire filter structure for battery packs. Background technique [0002] With the increasingly serious energy shortage crisis, traditional fuel vehicles are gradually being replaced by new energy vehicles, among which pure electric vehicles are widely used. As the power source of pure electric vehicles, battery packs have an important impact on the safety performance of pure electric vehicles. At present, in order to prevent flames from being ejected from the battery pack when the battery pack is thermally out of control, an explosion-proof valve is usually installed on the battery pack shell. However, due to the poor fire filtering performance of the existing explosion-proof valve, it cannot meet the high-intensity thermal runaway requirements of the battery pack. . Contents of the invention [0003] In view of this, the present invention aims to propose a fire filter ...
