Stream row 100 forms the entirety being easily installed.Junctional membrane 150 is preferably sheet, the confluence that junctional membrane 150 and collection plate 110 are formed
100 lighter in weight are arranged, thinner thickness is conducive to the energy density for improving battery modules 200.
An optional implementation according to the present invention, the busbar connector 100 of battery modules further include at least two for not
With the leading-out piece 140 connected between battery modules 200, each leading-out piece 140 is connected with a connection sheet 120.
For leading-out piece 140 for realizing the connection between different battery modules 200, leading-out piece 140 and connection sheet 120 are conduction
Body, leading-out piece 140 can be integrally formed with connection sheet 120.
Another optional implementation according to the present invention, the busbar connector 100 of battery modules further include for collection voltages
And/or the chip 112 of temperature, and installed for the Wiring harness connector 113 of communication with the outside world, chip 112 and Wiring harness connector 113
On collection plate 110.
Chip 112 is mounted on collection plate 110, and is spaced apart with avoid holes 111.Voltage and/or temperature etc. acquire signal
Data exchange can be completed by Wiring harness connector 113 and extraneous communication.
As shown in Figures 4 to 6, the battery modules 200 of embodiment include battery core group and above-mentioned according to a second aspect of the present invention
The busbar connector 100 of battery modules；The battery core group includes the battery core 210 of several arranged in parallel, is separately mounted to each battery core
The Positive Poles 212 and negative pole 213 of 210 tops, are equipped with explosion-proof valve 211 in each battery core 210, explosion-proof valve 211 is located at
Between Positive Poles 212 and negative pole 213, explosion-proof valve relief portion is matched with explosion-proof valve 211, connection sheet 120 and positive pole
Column 212 or/and negative pole 213 are connected to realize the series-parallel connection between several battery cores 210.
The battery modules 200 of the embodiment of the present invention include but is not limited to lithium-ion-power cell mould group, such as VDA mould group, electricity
Core 210 is also not necessarily limited to ternary battery core.As shown in figure 5, explosion-proof valve 211 is oblong explosion-proof valve 211 in battery core 210, correspondingly, such as
Shown in Fig. 1, collection plate 110 is equipped with and the one-to-one avoid holes 111 of explosion-proof valve 211, wherein 111 quantity of avoid holes and size
It is identical as explosion-proof valve 211.
An optional implementation according to the present invention, collection plate 110 are mounted on Positive Poles 212 and negative pole 213
Between.As shown in Figure 4 and Figure 5, the height of Positive Poles 212 and negative pole 213 is higher than explosion-proof valve 211, and collection plate 110 is set
Set the space that can be efficiently used in battery modules 200 between Positive Poles 212 and negative pole 213.
In above-described embodiment, the explosion-proof valve relief portion is by taking avoid holes 111 as an example；In other embodiments, described anti-
Quick-fried valve relief portion can be evacuation block, and the evacuation block can successfully be detached from 110 shape of collection plate when explosion-proof valve 211 is opened
At avoid holes, so that high temperature and high pressure gas, liquid that battery cell is sprayed are smoothly discharged from the avoid holes of formation.It is described to keep away
Allow block can for 110 integrally connected of collection plate, Weak link is formed in the evacuation block and 110 junction of collection plate, for example, leading to
It crosses and forms the evacuation block by heating indentation process on collection plate 110, since the connection thickness at impression is than collection plate 110
Ontology is thin, when battery cell sprays high temperature and high pressure gas or liquid, under the impact of high pressure gas or liquid, at impression first
Fracture, so that making the evacuation block successfully be detached from collection plate 110 forms avoid holes.The evacuation block can also be and collection plate
110 are flexibly connected, for example, increasing by a hat shape with marginal ridge at the avoid holes 111 on collection plate 110 and avoiding block, the hat shape
The central projection position for avoiding block passes through avoid holes 111, and the marginal ridge of the hat shape evacuation block is located at the acquisition on 111 periphery of avoid holes
Under plate 110, when battery cell sprays high temperature and high pressure gas or liquid, under the impact of high pressure gas or liquid, the hat shape
Evacuation block is successfully detached from collection plate 110 after marginal ridge deformation and exposes avoid holes 111.Using evacuation block, both can normally make
Dust-proof from used time, waterproof action, and avoid holes can be successfully formed when explosion-proof valve is opened.
The other structures of battery modules 200 according to an embodiment of the present invention and operation are to those skilled in the art all
It is to be understood that and easy to accomplish, therefore is not described in detail.
