The invention provides a battery module capable of delaying thermal runaway and a vehicle using the battery module, and belongs to the field of lithium ion battery detection; the battery module comprises a box body and a plurality of thermal runaway sealing assemblies, the plurality of thermal control sealing assemblies have the same structure and are arranged in the box body side by side, and theadjacent thermal runaway sealing assemblies are electrically connected to form a module; the box body comprises a front end plate and a rear end plate; each thermal runaway sealing assembly comprisesa housing and at least two battery cells, foam for buffering and heat insulation is arranged between the adjacent battery cells, the housing wraps the outer sides of the battery cells, the upper endof the housing is arranged in a sealed mode, and openings are formed in the two sides of the housing and correspond to the front end plate and the rear end plate of the box body; each thermal runawaysealing assembly, the front end plate and the rear end plate form an independent sealing unit. The thermal runaway speed of the module is effectively reduced, and thermal spreading is effectively reduced.
本发明提供了延缓热失控的电池模组及使用其的车辆,属于锂离子电池检测领域,包括箱体和多个热失控密封组件,多个热控密封组件的结构相同且并排设置在箱体内,相邻的热失控密封组件之间电连接形成模组;箱体包括前端板和后端板;热失控密封组件包括罩壳和至少两个电芯,相邻的电芯之间设有缓冲隔热用的泡棉,罩壳包覆在电芯的外侧,罩壳的上端密封设置,两侧开口设置且与箱体的前端板和后端板对应设置;每个热失控密封组件与前端板、后端板形成独立密封的单元。本发明有效减缓模组热失控的速度,有效减缓热蔓延。
