Specific embodiment
Core of the present invention is to provide a kind of battery cell mould group, can effectively ensure that overcurrent between battery modules stablize with
And the requirement of super-high-current.
In order to enable those skilled in the art to better understand the solution of the present invention, with reference to the accompanying drawing with embodiment to this
Invention is described in further detail.
Fig. 1 and Fig. 2 are please referred to, Fig. 1 is the main view of battery cell mould group provided by the present invention；Fig. 2 is institute of the present invention
The side view of the battery cell mould group of offer.A kind of battery cell mould group provided by the present invention, including battery core 2, have battery core 2 pacify
Dress hole and snap-gauge 1, copper sheet 3 and the nickel plating steel disc 4 being fixed in battery core 2.3 laser spot welding of copper sheet is on nickel plating steel disc 4, battery core
2 two electrodes are connect by spot welding with nickel plating steel disc 4.Riveting contact area compared to the prior art is small, poor contact is led
The overcurrent of cause is unstable, a kind of battery cell mould group that this programme provides, and is welded nickel plating steel disc and copper sheet by laser spot welding
It is connected together, laser welding is smooth, and welding can allow entire plane contact area bigger and contact firm, Neng Gouyou compared to riveting
Effect guarantees the requirement of overcurrent stabilization and super-high-current between battery modules.
Further, copper sheet 3 is that I-shaped laser spot welding is connect with nickel plating steel disc 4, the I-shaped firmness for increasing spot welding.
The area of copper sheet 3 is less than the area of nickel plating steel disc 4, and the periphery battery overcurrent of battery cell mould group electrode end margin uses nickel-plated steel
4 overcurrent of piece can not only meet the requirement of battery overcurrent, moreover, effectively reducing the area of copper sheet, reduce costs, alleviate
The weight of battery cell mould group entirety.
It is provided with heat release hole on copper sheet 3 and nickel plating steel disc 4, is acted on for battery ventilation and heat.
Screw through hole 5 is equipped at snap-gauge 1, nickel plating steel disc 4 and 3 relative position of copper sheet, screw rod passes through 5 fastening group of screw through hole
Battery cell mould group after dress, battery cell mould group is integrally fixed.
Snap-gauge 1 includes bottom plate, is arranged on bottom plate and the mounting hole for limiting battery core position and setting are in bottom plate
Support column.Mounting hole arranged by row's parallelly distribute on and close-packed arrays, and adjacent mounting hole is staggered arrangement in adjacent two rows.
Wherein, bottom plate is provided with heat release hole between the mounting hole adjacent in adjacent row, is used for battery ventilation and heat.Support column is used
In support battery cell mould group.When using a snap-gauge 1 in battery cell mould group, two tables up and down of bottom plate are arranged in support column
On face, the support of entire battery cell mould group is provided.In battery cell mould group when using two or more snap-gauges 1, it is located at electricity
The support column of two snap-gauges 1 at core electrode both ends is arranged on a side surface of bottom plate, other are located at the card among battery core electrode
Two surfaces up and down of bottom plate are arranged in the support column of plate 1, and adjacent snap-gauge 1 is mutually abutted by support column, provide entire battery
The support of loose pattern group.Snap-gauge only wraps up battery core sub-fraction surface area, and other parts are relatively exposed, not to battery core into
Row is fully wrapped around, therefore can preferably radiate.Alternating expression arrangement mode makes on the snap-gauge of same area, except each mounting hole with
Outer residual area is minimum, and the distribution of mounting hole maximum can utilize battery snap-gauge space.And it is opposite make snap-gauge weight compared with
Gently, weight reaches most lightization in the case where substantially meeting structural strength as far as possible.Battery core arrangement can effectively be saved using the snap-gauge
Space makes battery core reach maximum space utilization rate in battery cell module internal.
The attaching nut for connecting between battery cell mould group is additionally provided on the side of snap-gauge 1.Adjacent cell mould group
Blending bolt is connected at the attaching nut position on snap-gauge 1 by connector to connect, attaching nut can by welding or
Integral type is located on snap-gauge 1, and the serial or parallel connection reached between battery cell mould group is fixed.Wherein, connector can use aluminium
Plate, because battery cell mould group has been fixedly secured with screw rod, aluminium sheet connection can achieve light-weight, contact smooth mesh
's.
Copper sheet 3 has bending side, the bending side and attaching nut's corresponding position of copper sheet 3 in the attaching nut side of snap-gauge 1
Place has hole location notch 6, and 6 sets of hole location notch on attaching nut.As long as the benefit of this hole location notch 6 is by 4 He of nickel plating steel disc
After the weldment of copper sheet 3 welded is put into, 6 sets of hole location notch on attaching nut, position up and down can be automatically positioned
It is good, without any tool locating can spot welding battery, be just assembled into a battery modules.Wherein, copper sheet 3 is with nickel plating steel disc 4
I-shaped laser spot welding connection, the I-shaped center for being just in battery core of nickel plating steel disc.
Furthermore a kind of battery provided by the invention, the above-mentioned battery cell mould group of the battery applications.Using above-mentioned battery cell
