Embodiment Construction

[0020] The present invention will be further described below in conjunction with the embodiments and the accompanying drawings.

[0021] Such as figure 1 , figure 2 As shown, it is the connecting device of the preferred embodiment proposed by the present invention, which includes: a battery connecting piece 1, the two wings of which are welding areas 11; and a pair of module connecting pieces, which are the first module Connecting piece 21, the second module connecting piece 22, and one side of each module connecting piece is welding zone 23 and the other side is bolt connecting zone 24, and the bolt connecting zone 24 of two module connecting pieces overlaps and can be used Bolt 3 is fixedly connected. In this embodiment, the vertical recess 12 is formed by bending downwards between the two wing welding areas 11 of the battery connection piece 1 . The distance between the two outer sides of the vertical recess is equal to the distance between the poles of the two single b...

Abstract

The invention discloses a connecting device and a battery module. The connecting device comprises: a battery connecting piece; two wings of the battery connecting piece are welding areas; The invention also comprises a pair of module connecting pieces, one side of the module connecting pieces is a welding area and the other side is a bolt connecting area, and the bolt connecting areas of the two module connecting pieces are overlapped and bolted to be fixed. The invention synthesizes the advantages of two connection modes of welding and bolt connection, ensures the reliability and stability ofbattery connection, and improves the flexibility of module connection collocation and assembly efficiency.

Description

technical field [0001] The invention relates to the field of lithium ion battery technology, in particular to a connection device and a battery module used for a plurality of batteries connected in series and parallel to form a group. Background technique [0002] With the development of science and technology, the application of lithium-ion battery technology is becoming more and more extensive. At present, for batteries used in electric vehicles or energy storage scenarios, it is generally necessary to connect individual batteries in series and parallel to form battery modules (groups) in order to meet the performance requirements of various power consumption. The connection methods between the batteries are mainly: Welding, bolting, wire bonding, etc. However, battery modules with different connection methods have their own advantages and disadvantages in terms of connection stability, safety, and convenient operation. The actual defects will directly affect the normal u...
