Abstract
The invention discloses a battery module connecting device and a battery module, the connecting device comprises: a substrate provided with a membrane cavity, a plurality of through holes formed in the substrate, each through hole penetrating through the membrane cavity, and a positive electrode output port and a negative electrode output port formed in the substrate; the conductive film is arranged in the film cavity and comprises a plurality of sub-films, one part of the sub-films at the head end and the tail end is located at the positive electrode output port, the other part of the sub-films at the head end and the tail end is located at the negative electrode output port, one of the sub-films at the head end and the tail end is provided with a plurality of positive electrode connecting ends, and the other one of the sub-films at the head end and the tail end is provided with a plurality of negative electrode connecting ends; one of two opposite ends of the other sub-films is provided with a plurality of positive electrode connecting ends, the other end of the other sub-films is provided with a plurality of negative electrode connecting ends, the negative electrode connecting ends of one of any two adjacent sub-films are in one-to-one correspondence with the positive electrode connecting ends of the other sub-film, and the positive electrode connecting ends are equal to the through holes in number and are in one-to-one correspondence with the through holes; the positive electrode connecting end and the negative electrode connecting end are both partially located in the through hole. The battery pack integrates a busbar function, and no open wire is exposed when the battery cells are connected.
Description
technical field [0001] The invention relates to the technical field of batteries, in particular to a connection device for a battery module and the battery module. Background technique [0002] The battery modules of the existing cylindrical cells are generally welded on both sides or on one side, and the collection of the wire harness is mostly wire collection, PCB board or FPC board collection. With the above-mentioned traditional design, there will be unreliable connection or fixation of the wire harness with the PCB or FPC, which is prone to failure problems or even safety problems. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, an object of the present invention is to propose a connection device for a battery module, which can solve the problem of unreliable connection and safety problems caused by the connection between the battery cell and the PCB or FPC through a...
