Abstract

The invention discloses a soft cell module. The module comprises a bottom plate, a protecting frame assembly, at least two soft cores which are parallelly arranged, at least one first insulation panel, at least on second insulation panel, at least one first busbar which is used for leading out positive electrodes of each soft core and at least one second busbar which is used for leading out negative electrodes of each soft core. A first adhesive fills the gaps between the insulation panels and the busbars and the gaps between the busbars and the soft cores, the insulation panels and side plates are bonded through a second adhesive, outer frames and other structural components used for fixing in an existing cell module can be replaced with the first adhesive and the second adhesive, and therefore the weight of the soft cell module is greatly reduced while the structure of the cell module is ensured. The bottoms of the soft cores are connected with the bottom plate through a heat thermalconductive adhesive to achieve the uniform heat dissipation of the cores and the reduction of the using temperature of the cell module.

Description

technical field [0001] The invention relates to the technical field of power batteries, in particular to a soft pack battery module. Background technique [0002] With the gradual popularization of new energy vehicles, people pay more and more attention to the performance of the vehicle power battery system. The power battery system of new energy vehicles is composed of several batteries connected in series and parallel. According to the system level, from high to low, it is divided into battery packs, battery modules, and batteries. Most of the battery modules produced by lithium battery manufacturers at home and abroad use the battery cell as the smallest unit, that is, the battery cell is produced first, and then the corresponding structural parts and circuit connectors are matched to form a battery module through series and parallel connection, and finally the battery module is assembled. The battery pack is formed by the battery pack case and cover, and module-level c...
