Description

A kind of soft-package battery unit module

Technical field

The utility model relates to battery technology fields, and in particular to a kind of soft-package battery unit module.

Background technique

It is higher and higher to the manufacturing process requirement of power battery with the development of electric car, but manufacturing cost requires It is greatly lowered, this requires the directions of power battery manufacture towards standardization, automation to develop.In recent years, soft pack cell because It possesses unique aluminum plastic film encapsulating structure, and safety is good, energy density is than high, and Soft Roll is more next in the accounting of power battery industry It is higher.

Soft-package battery block structure for electric vehicle is complicated at present, most for fixed vehicle customization, is unfavorable for batch certainly Dynamic metaplasia produces, and mostly uses natural heat dissipation, and effect is undesirable, is mainly manifested in: first is that being fixed using entire mould group, single Soft Roll Battery core is not fixed firmly, and soft pack cell uses encapsulating structure, is not fixed easily, and since car body shakes for a long time after entrucking, is caused in case Mould group soft pack cell is fixed unstable, influences tab connection contact.Second is that directly in groups using single soft pack cell, being unfavorable for automatic Metaplasia produces, and stable manufacturing process is poor.Third is that when there is large current density, soft pack cell it is poor from heat-sinking capability, in groups it Heat is dredged not in time afterwards, Yi Yinqi thermal runaway.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies of above-mentioned background technique, provide a kind of compact-sized, connection jail Gu, the soft-package battery unit module structure of good heat dissipation effect.

A kind of the technical solution of the utility model thus are as follows: soft-package battery unit module, it is characterised in that: the Soft Roll electricity Pool unit module includes the soft pack cell unit that several are set side by side, and is folded between every two adjacent soft pack cell unit Radiating fin, radiating fin two sides are attached at the surface of two neighboring soft pack cell respectively, and the two sides of radiating fin are to electricity Radiating fin radiating part is extended to form outside core support；The soft pack cell unit lateral surface of front and rear ends is buckled with end casing respectively, The corresponding position in the periphery of the end casing and soft pack cell unit, which is equipped with multiple bolts hole and is bolted, is linked as one Body.

Further improvement to above-mentioned technical proposal is: being equipped between the end casing and forward and backward soft pack cell unit The buckle structure that matches and by be cooperatively connected realize it is preliminary fixed.

Further improvement to above-mentioned technical proposal is: being equipped with clamp on the outside of the frame of the battery core bracket, and passes through The cingulum of cooperation makes to be interconnected to form entirety between adjacent soft pack cell unit.

Further improvement to above-mentioned technical proposal is: the end casing uses the aluminium sheet compression moulding of 0.2mm, end cap Plate is equipped with the lines of outwardly convex.

Further improvement to above-mentioned technical proposal is: the radiating fin is the aluminium flake of 0.1mm, radiating fin heat dissipation Portion uses L shape bending structure, and radiating fin radiating part is equipped with the evacuation gap for buckling mounting structure.

The utility model has the advantages that the utility model have it is compact-sized, be connected firmly, the characteristics of good heat dissipation effect.

Preliminary fixed, soft pack cell list is realized by snapping fit attachment between end casing and adjacent soft pack cell unit Pass through between member and snap fit attachment to form overall structure, then be closely connected and fixed and be integrated by bolt bar, keeps Soft Roll electric The structure of pool unit module is stronger, while realizing the groups of purpose of soft pack cell series connection.

End casing uses 0.2mm aluminium sheet die mould, is from the aspect of cost, weight and processing performance, thickness using aluminium sheet Primarily to increasing its plasticity and rigidity, the lines that surface sets protrusion can buffer shape caused by soft pack cell fever bulging for limitation Become.

Radiating fin selects the aluminium flake of 0.1mm, quality-high and inexpensive from cost consideration, light-weight, corrosion-resistant, and specific heat capacity is big, hot Transmission effect is good；Radiating fin radiating part uses bending structure, it is therefore an objective to increase heat dissipation area, and heat management system only need to be to soft The aluminium flake of packet battery cell module two sides carries out cooling processing, that is, can reach the mesh that the high heat inside unit module is dredged 's；Evacuation gap is provided with convenient for setting buckle structure, saves space, structure is more reasonable.

Detailed description of the invention

Fig. 1 is the utility model packing schematic diagram.
