Technical field
The present invention relates to new energy battery modules electric connection technology field, specially a kind of new energy battery modules electrical connection
Structure.
Background technique
Battery modules are made up of multiple battery cores centainly string and relationship connection.In charge and discharge process, between different battery cores
Transmit electric current by metallic conductor connection, the positive and negative terminals of usual metallic conductor and battery core use welding procedure.Metallic conductor
It is commonly called as Busbar, material generally selects copper, aluminum or aluminum alloy, nickel, steel etc..By the hardness condition of Busbar, it is generally divided into hard
Busbar(is hereinafter referred to as arranged firmly) and the hereinafter referred to as soft row of soft Busbar().
Hard row generally cuts processing or Sheet Metal Forming Technology forms, this technical maturity by washing to plate machinery, processing cost compared with
It is low, but hard row is relatively high due to part hardness, it is difficult to be sized and form, there is larger size tolerance between battery core with this
When, row may be bonded bad with battery core pole surface firmly, influence welding quality；In addition mould group vibration and battery core expand with heat and contract with cold and
When circulation expansion, larger stress is generated between hard row and battery electrode column, may cause battery core pole leakage.
Soft row is usually that (such as macromolecule expands to special superpressed technique is locally carried out after sheet metal (0.1 ~ 0.2mm) lamination
Dissipate welding etc.) processing, corresponding battery electrode column weld near zone, soft row be press-fitted together as one, and other regions still
Stack of sheets state.Adjustable size is also adapted to mould group and shakes soft row in a certain range to adapt to battery core dimensional tolerance
The circulation expansion variation of dynamic and battery core, substantially reduces the internal stress occurred in hard row, reduces battery core leakage risk.Due to soft row's technique
Relative complex, cost of parts is higher, and sheet metal hardening process, and homogeneity of product is poor, when between layers of foil there are greasy dirt or
When impurity, the hardening region phenomenon inconsistent there are layers of foil peeling force, and then soft row's welding is influenced, there is the fried fire of welding, welding
It is insecure etc., influence battery group welding quality.
In square electric cell structure, battery core lamina tecti generally has the distance of 2 ~ 6mm to battery core pole, in module design, leads to
Busbar is often welded on battery core pole upper surface, the height space of this 2 ~ 6mm does not utilize, and causes to waste.To improve mould
Group group efficiency also utilizes this segment space upper, a new busbar of design, while also solving existing for soft row and hard row
Some drawbacks.
Summary of the invention
The purpose of the present invention is to provide a kind of new energy battery modules electric connection structures, this electrical connector, structure is simple,
Technical maturity, it is easy to accomplish automated production is conducive to control cost.
To achieve the above object, the invention provides the following technical scheme: a kind of new energy battery modules electric connection structure, packet
It includes the conductive metal sheet one and conductive metal sheet two for connecting battery plus-negative plate, the conductive metal sheet one and described leads
Hard row is connected between electric metal piece two.
Preferably, the conductive metal sheet one and conductive metal sheet are second is that one layer of sheet metal or no less than one layer of superposition
Sheet metal.
Preferably, the conductive metal sheet one and conductive metal sheet two are by one section of planar sheet metal and one section of curved
Sheet metal composition, wherein planar sheet metal is welded with corresponding battery core pole, curved sheet metal has certain size adjustment
Function.
Preferably, the conductive metal sheet one and two thickness of conductive metal sheet are smaller than arranging firmly.
Preferably, the conductive metal sheet one and conductive metal sheet two can be by connecting other hard row and conductive metal
Piece extension connection.
Compared with prior art, beneficial effects of the present invention are as follows:
One, the present invention is by setting conductive metal sheet one and conductive metal sheet two, and thickness is smaller than arranging firmly, one He of conductive metal sheet
Conductive metal sheet two has certain size stretch function, can adjust battery core dimensional tolerance itself, battery core in groups when conductive metal
Piece one and conductive metal sheet two and battery core pole good fit effectively solve pole weld failure risk.
Two, the present invention passes through the characteristic of conductive metal sheet one and conductive metal sheet two, conductive metal sheet one and conductive metal
Piece two has size adjusting function, can avoid in battery use process, with the ruler to expand with heat and contract with cold and battery core circulation expansion generates
Very little variation effectively eliminates the internal stress between mould group part, reduces battery core leakage risk.
Three, the present invention is by the architectural characteristic of conductive metal sheet one and conductive metal sheet two, and conductive conveyance capacity can be with
It is limited in a certain range, when electric current is more than threshold values, conductive metal sheet one and two structure of conductive metal sheet fuse, i.e. cutting electricity
Source plays " fuse " function, effectively improves the safety of battery modules.
Four, the present invention passes through the architectural characteristic of conductive metal sheet one and conductive metal sheet two, and conductive metal sheet is than relatively thin, weldering
The power for connecing demand is small, and the calorific value of generation is also small, reduces battery core pole design difficulty, improves battery core pole Welding Safety.
It five, can effective benefit when the design of row's portion of upper surface is lower than two upper surface of conductive metal sheet one and conductive metal sheet firmly
With the space between battery core pole and battery core top cover, mould group group efficiency is improved, mould group is more compact.
Six, the present invention solves deposits between peeling force inconsistence problems, soft row's layers of foil between soft row's stiffened regional metal layers of foil
The problem of impurity greasy dirt influences mould group welding, size adjusting ability is poor in use by hard row, and stress leads to battery leakage
After the problem of the problem of risk, soft row's processing technology complexity high expensive and soft row or hard row are welded on pole, replace again
The problem of soft row or hard row's difficulty.
