Problems solved by technology

[0003] The battery modules currently used do not have the heat dissipation function of the battery cells in structure, so that the battery modules cannot perform good heat exchange with the outside world. The energy accumulated in the thermal runaway of the battery module cannot be released quickly through heat conduction and heat dissipation and gas discharge, which will cause more serious accidents such as fire and explosion

Abstract

The invention relates to a pouch battery module comprising a module bottom plate and a battery unit, wherein the battery unit comprises two parallel pouch battery cells and a fixing bracket for fixing the pouch battery cells; a fireproof insulating thermal insulation layer is disposed between the two pouch battery cells; a heat-conducting aluminum plate is disposed on the outer side of the fixing bracket and is closely attached to the pouch battery cells; an outer side of the heat-conductive aluminum plate is covered with an insulating protective film; the module bottom plate is provided with a groove that is engaged with the fixing bracket and the heat-conducting aluminum plate; and the bottom of the heat-conducting aluminum plate is fixed to the module bottom plate by a thermal conductive adhesive. The pouch battery module can delay the process that the thermal runaway of a normal battery cell is triggered by the thermal runaway of an adjacent battery cell in the extreme case, and can quickly release the thermal runaway energy by a liquid cooling system in the extreme case, thereby effectively extending the overall thermal runaway time of the battery module and a battery system and ensuring the personal safety of passageers on an electric vehicle.

Description

technical field [0001] The invention relates to a battery module, in particular to a soft pack battery module. Background technique [0002] With the gradual promotion and popularization of electric vehicles, the safety issues of electric vehicles, especially battery systems, also follow. As the smallest unit in the battery system - the safety design of the battery module is undoubtedly the top priority. [0003] The battery modules currently used do not have the heat dissipation function of the battery cells in structure, so that the battery modules cannot perform good heat exchange with the outside world. The energy accumulated in the thermal runaway of the battery module cannot be released quickly through heat conduction and heat dissipation and gas discharge, which will cause more serious accidents such as fire and explosion. Contents of the invention [0004] The purpose of the present invention is to provide a pouch battery module, which can enable the battery modu...
