Description
[technical field]
The present invention relates to a kind of for clamping the soft-package battery support of soft-package battery
[background technology]
Along with petroleum resources day by day reduce and the pollution of environment day by day serious, protection of the environment, energy-saving and emission-reduction have become current trend and trend in the world.Under this background, in recent years, the motor vehicle that the battery of take is main power source or partial power source (mainly comprises hybrid electric vehicle, plug-in hybrid electric vehicle, pure electric vehicle) engender and increasing, the carbon emission amount of motor vehicle is less than traditional combustion engine automobile, and the carbon emission of pure electric vehicle is even zero, and have the advantages that energy conversion efficiency is high, this makes people electric automobile is considered as to an important selection of following replace internal combustion engines car.
At present, the main selection of electric automobile power battery is lithium ion battery, traditional cylindrical lithium ion battery (common are 18650 types, 26650 types) although be widely used in 3C Product (mobile phone, computer, digital camera) power supply, but traditional lithium ion battery is due to itself character of material and the impact of shape design, easily produce thermal runaway phenomenon, lithium ion battery burning just occurred repeatedly in cells in notebook computer field and cause the event of recalling.This make people by lithium ion battery when being applied to electric automobiles, be faced with the test of fail safe.So, in order to improve the security performance of lithium ion battery, in recent years, people develop the lithium ion battery of some new structures in succession, soft-package battery (soft-bag battery or claim coffee-bag battery) for example, compare with traditional column lithium ion battery, soft-package battery or rectangular cell have than columniform lithium ion battery and have better heat dispersion.So current most electric automobiles adopt soft-package battery monomer to form electrokinetic cell bag.
Current soft-package battery or be generally flat, has lug in a side of battery or relative both sides, and lug is generally also flat.It is shell that soft-package battery generally adopts aluminum plastic film.Adopt heat pressing process by battery core part (positive pole, negative pole, barrier film) be encapsulated in aluminum plastic film, after soft-package battery moulding, at mid portion, be generally the body part (battery core part) with certain thickness (being generally several millimeter～mono-centimetre of left and right), all there is the edge part being formed by two aluminum plastic films stacks in Er edge.The width of marginal portion is generally one centimetre of left and right.But edge part is on soft-package battery, there is no Essential Action not eliminable part again.And edge part is easily bent or tears, even cause the damage of battery body.
The existence of soft-package battery edge part, that also gives soft-package battery has brought inconvenience in groups; At present soft-package battery in groups general adopted method be: first the soft-package battery of some is placed in the battery case of a shape box like or chest, and then the lug of soft-package battery is connected or is connected in parallel, the size of this battery case is greater than the length of soft-package battery and width and the stack of a plurality of soft-package battery and the thickness that forms, and final total lug (collector) extends chest.So just, form a soft package battery module, and then a plurality of soft package battery modules are constituted to soft-package battery bag.
There are some shortcomings in above-mentioned this design, first, the size of battery case is larger than the combination of a plurality of soft package battery modules, is assembled into after battery module the volume energy density of whole module lower; Secondly, a plurality of soft-package batteries in battery case are generally superimposed, between soft-package battery, generally there is no fixed mechanism, in use, owing to jolting or shaking, between soft-package battery, may there is relative displacement, thereby produce extruding or the kinking of battery cell or lug, the reliability of whole battery module is reduced.
[summary of the invention]
Content of the present invention is: first a kind of soft-package battery support is provided, can be used for clamping soft-package battery; Make soft-package battery edge part not fragile, in addition, can also make stacking in groups of soft-package battery convenient simple and easy.
In order to achieve the above object, first the present invention provides a kind of soft-package battery shell, and its technical scheme adopting is:
A kind of soft-package battery support, be used for clamping soft-package battery, it comprises the framework being square, and described framework is hollow structure, in the one side of described framework, be provided with a plurality ofly for connecting the projection of framework, at the correspondence position of described framework another side, be provided with a plurality of for holding the groove of connector.
As preferred technical scheme: offer a plurality of the first through slots in described framework.
As preferred technical scheme: offer at least one for the groove of fixed strip is set on the side of described framework, the depth direction of described groove is parallel to described side.
As preferred technical scheme: offer a plurality of the second through slots on the side of described framework, the depth direction of described the second through slot is perpendicular to described side, and the first described through slot is connected with the second through slot.
By the framework of soft-package battery support, can clamp the edge part of soft-package battery, make edge part not fragile, between two soft-package battery supports, can interfix by projection and groove, can adopt the such pattern of soft-package battery support-soft-package battery-soft-package battery support-soft-package battery-soft-package battery support-soft-package battery to stack fast fixedly soft-package battery, what make soft-package battery becomes easier in groups.
On the other hand, owing to having offered the first through slot and the second through slot on framework and side, make the heat dispersion of soft-package battery better, also alleviated on the other hand the weight of soft-package battery support, and the weight of soft-package battery bag in groups.
