Description
[technical field]
The utility model relates to battery technology fields, and in particular to a kind of battery modules that overcurrent is carried out by pressing.
[background technique]
With the development of New-energy electric vehicle, wanted for the capacity of battery case, volume, battery core combination, heat dissipation and fixation
Ask higher and higher, it is necessary to have a more reasonable structure, composition density is higher, reasonable structure, reliable installation battery modules, to reach
To the requirement for meeting battery case security performance.
The structure of traditional battery modules is as depicted in figs. 1 and 2, and upper end passes through copper bar between adjacent two battery modules 1'
2' connection, centre are provided with confluence piece (copper sheet+nickel sheet) 3', and battery module two is equipped with end plate and is assembled by long bolt.Its
Overcurrent mode is to import next module after leading by piece (copper sheet+nickel sheet) 3' that converges to upper end copper bar 2', forms mould group
Cascaded structure.This structure existing defects is as follows:
1, the copper bar of each module is fixed by bolts, and technique is relatively complicated, and when bolt quantity is excessive, entire
Reliability inside battery system reduces；And copper bar quantity is more, it is at high cost.
2, it is that copper sheet and nickel sheet are formed by laser welding that busbar connector is currently used, and the material cost of such structure is opposite
It is higher.
It 3, when overcurrent designs is designed according to ordinary circumstance.But practical vehicle is in application, may result in high current
Electric discharge, and the duration is longer, is easy to cause copper bar temperature rise higher, increases heat production source inside battery pack, so as to cause battery system
Temperature rise of uniting is excessively high and influences to use.
4, the distance of this structure design overcurrent is big, the loss of electric current when may result in overcurrent.
[utility model content]
The technical problem to be solved by the utility model is to provide one kind, the cost of material is low, overcurrent loses few electricity
Chi Mo group.
The utility model is realized in this way:
A kind of battery modules carrying out overcurrent by pressing, including multiple battery modules, multiple intermediate copper sheets or aluminium flake,
Multiple long bolts, two end plates；
The multiple battery module is arranged side by side, and an intermediate copper sheet or aluminium is arranged between every adjacent two battery module
Piece, two battery modules for coming outermost end are respectively arranged with an end plate, by multiple long bolts by the multiple electricity
Pond module, multiple intermediate copper sheets or aluminium flake, two end plates are connected, and form battery modules.
Further, the battery module, including a battery core, a bracket, a nickel sheet；The battery core is arranged in the bracket
It is interior；The battery core and bracket pass through nickel sheet described in resistance welding.
Utility model has the advantages that the 1, cost of reduction battery system and the type using material；2, bolt is reduced
Fixed structure, provides production efficiency, promotes the reliability of battery system；3, overcurrent design and practice operating condition difference are solved
Lead to the problem that temperature rise is excessively high.
[Detailed description of the invention]
The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is structural relation schematic diagram between the two neighboring battery module of the prior art.
Fig. 2 is the overcurrent schematic diagram of the prior art.
Fig. 3 is structural relation schematic diagram between the two neighboring battery module of the utility model.
Fig. 4 is the utility model battery module structure schematic diagram.
Fig. 5 is the overcurrent schematic diagram of the utility model.
[specific embodiment]
As shown in Figures 3 to 5, a kind of battery modules carrying out overcurrent by pressing, including it is multiple battery modules 1, more
A intermediate copper sheet or aluminium flake 2, multiple long bolts 3, two end plates 4.
Multiple battery modules 1 are arranged side by side, and an intermediate copper sheet or aluminium flake is arranged between every adjacent two battery module 1
2, two battery modules 1 for coming outermost end are respectively arranged with an end plate 4, will be the multiple by multiple long bolts 3
Battery module 1, multiple intermediate copper sheets or aluminium flake 2, two end plates 4 are connected, and form battery modules.
The battery module 1, including a battery core 11, a bracket 12, a nickel sheet 13；The battery core 11 is arranged in the branch
In frame 12；The battery core 11 and bracket 12 pass through nickel sheet 13 described in resistance welding.
Course of work explanation:
Battery module 1 is made up of battery core 11, bracket 12, nickel sheet 13 resistance welding, is put between module and module
Between copper sheet/aluminium flake 2 module and intermediate copper sheet/aluminium flake are closely pressed together on together by long bolt 3 and both sides end plate 4.It sets
Timing need to consider the pressure that bracket 12 can bear, and need to ask surface roughness, flatness of bracket etc., need to consider that vehicle uses
It is the torsion decaying etc. after vibrating for a long time, can all influences the pressure force of its mould group and the contact area of intermediate copper sheet/aluminium flake, from
And influence overcurrent capability.
Overcurrent design: the electric current of battery core 11 is imported into nickel sheet 13 by electric resistance welding position, then passes through 13 He of nickel sheet
The close pressing of intermediate copper sheet/aluminium flake 2 carries out overcurrent, imported into next module, forms mould group cascaded structure.Due to centre
The close contact of copper sheet/aluminium flake 2 and nickel sheet 13, structure is to carry out overcurrent with copper sheet/aluminium flake 2 among full wafer, so generally
Due to the copper bar temperature rise that overcurrent generates, can be ignored in the structure of scheme.
The design scheme of the utility model greatly reduces the type and the molding technique of material of material from structure.And
During the manufacturing, reduce the production process in factory.When total system forms, the plastics of fastener are greatly reduced, are mentioned
The high reliability of system reduces since fastener is decayed bring risk after vibration.It is set by different overcurrent
Meter, avoiding may be since practical limit operates the problem of leading to system temperature rise.
The foregoing is merely the preferable implementation use-cases of the utility model, are not intended to limit the protection of the utility model
Range.Within the spirit and principle of the utility model, made any modification, equivalent replacement and improvement etc., should all wrap
Containing being within the protection scope of the utility model.
