Abstract

The invention provides a novel flexible connection structure and a battery module. A heat conduction structure is arranged on a flexible connection body, and the heat generated in a working process of the flexible connection body is transferred to a plurality of heat conduction fins by means of a heat conduction substrate on the heat conduction structure, so that the heat conduction of the flexible connection is realized; the plurality of heat conduction fins are available, so that the contact area between the heat conduction fins and air is larger, the heat is more rapidly dissipated to the air, and the temperature of the flexible connection is reduced. Therefore, batteries in the battery module are prevented from being influenced by the high-temperature flexible connection, so that the thermal instability is avoided, and the power supply safety of the battery module is improved.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a novel flexible connection structure and a battery module. Background technique [0002] The power battery used by electric vehicles is used as the source of vehicle power, and the power battery can contain multiple sets of battery modules. Since each battery module can contain multiple battery cells, multiple battery cells can also be connected in series or in parallel, and the positive electrodes of a battery module are respectively formed by providing connection parts on the positive current collector plate and the negative electrode current collector plate. or negative pole. When multiple groups of battery modules are connected in series or in parallel, the positive or negative electrodes of the two battery modules can be connected through a flexible connection. [0003] Due to the large number of single cells in the battery module, the current passing through the soft c...
