Description
Technical field
The utility model belongs to lithium battery group security technology area, and in particular to a kind of parallel-connection network with defencive function.
Background technology
Existing electric vehicle generally requires prodigious capacity, is only typically not reach requirement with single big battery series connection,
Always by connecting again in groups after many small-capacity cells parallel connections.In parallel connection, connection sheet or parallel-connection network are small by each
Capacity batteries connect, and constitute a high capacity cell.
Numerous battery cores peace that high capacity cell module (or battery pack) generally comprises battery clamp, is formed on battery clamp
Dress hole, the numerous shrapnels being placed in each battery core mounting hole, the numerous battery cores being plugged in each battery core mounting hole are (i.e. above-mentioned
Small-capacity cells) and the parallel-connection network that is connected in parallel each battery core in same layer, wherein parallel-connection network includes being arranged in
On same plane and numerous battery core connection gaskets of spaced distribution and numerous connections for being connected between each battery core connection gasket
Piece, each battery core connection gasket correspondence is arranged in each battery core mounting hole and is connected with corresponding battery core, thus will be same
One layer of each battery core is together in parallel.
Although the existing parallel-connection network with defencive function can provide protection, usually it is welded to form, processing is cumbersome,
And the existing usual battery core gasket of parallel-connection network is directly attached with battery core, is easily loosened during electric automobile during traveling, contact
It is bad, lead to failure in parallel, poor reliability.
Utility model content
The purpose of this utility model is to provide a kind of parallel-connection networks with defencive function, to solve in above-mentioned background technology
The problem of proposition.
To achieve the above object, the utility model provides the following technical solutions：A kind of parallel-connection network with defencive function, and
Networking is integrally formed, and the parallel-connection network includes that M rows N arranges several battery core connection gaskets of spaced distribution and is connected to institute
Several connection sheets between battery core connection gasket are stated, the battery core connection gasket is decussate texture, and the battery core connection gasket is by ten
Font center becomes narrow gradually to four sides, and the connection sheet width is less than four hem width degree of battery core connection gasket, in the battery core connection gasket
Centre is equipped with several salient points, and M and N are not less than 2.
Preferably, the salient point is four, and the salient point is uniformly distributed in battery core connection gasket center, opposite two salient points
Respectively with four side of battery core connection gasket on same straight line.
Preferably, the parallel-connection network two sides is equipped with salient point.
The technique effect and advantage of the utility model：
1, the punching press of parallel-connection network entirety makes, no welding, it is ensured that effective parallel connection of battery during vibrations；It produced
It is easy to operate without processing in journey, it uses manpower and material resources sparingly；
2,4 salient points are arranged in each battery core crossover location of parallel-connection network, increase battery core cathode contact reliability, prevent due to contact
Failure in parallel caused by bad；
3, there is parallel-connection network overcurrent protection function, two battery core contact site centre position connection sheet both sides to narrow, and work as battery
Group can preferentially be fused by position when abnormal high current, effectively prevent Anomalous Diffusion.
