Embodiment
The application is described in further detail below by specific embodiment and with reference to accompanying drawing.
As depicted in figs. 1 and 2, the embodiment of the present application provides a kind of battery modules, and the battery modules can be Soft Roll mould
Group, it includes housing, battery core 21 and cushion pad 22.Wherein：
Housing is used to provide protective action to structures such as battery core 21, cushion pads 22, and it can specifically include front end-plate, rear end
Plate 11 and the U-shaped side plate 12 being fixedly connected with front end-plate and end plate 11, end plate 11 can be made of metal, be preferably
Metal plate metal, front end-plate could be arranged to two, and one of them is plastic cement front end-plate 13, and another is metal front plate 14, should
Metal front plate 14 is preferably made up of metal plate metal, and plastic cement front end-plate 13 is arranged between battery core 21 and metal front plate 14, with
The impulsive force that this buffer battery module is subject to.U-shaped side plate 12 can by way of welding with metal front plate 14 and end plate
11 are fixed together.Certainly, housing can also use other structures.
Battery core 21 is usually arranged as multiple, and each battery core 21 can stack together along the thickness direction of itself, be carried with this
Rise the electric energy that battery modules can be provided.Cushion pad 22 is set between adjacent battery core 21 and/or between battery core 21 and housing, should
Cushion pad 22 includes at least two cushions, and each cushion is stacked to be fixed, and at least both modulus of elasticity in each cushion
It is different.Specifically, the gain of parameter such as quantity, the material of cushion, the thickness of cushion that can be by adjusting cushion
Required cushion pad 22.
If battery core 21 and the size of structural member are bigger than normal, due in each cushion of cushion pad 22, relative to modulus of elasticity compared with
Big cushion, the less cushion of modulus of elasticity is easier by compression, therefore during assembling battery modules, can be by somewhat
Increase external force and battery modules is reached Outside Dimensions, while it is empty to ensure that battery modules leave enough expansions in use
Between.If battery core 21 and the size of structural member are less than normal, because in each cushion of cushion pad 22, the larger cushion of modulus of elasticity is not
It is easily deformed, therefore by somewhat reducing external force module can be made to ensure Outside Dimensions, while also ensures battery modules early stage
In the presence of the requirement of certain pretightning force.
When installing above-mentioned battery modules, the larger cushion of the Elastic Modulus of cushion pad 22 can ensure between each parts
Pretightning force meet and require, and then substantially reduce the thickness and precision requirement of assembly parts, when battery modules in use by
When impulsive force or itself expansive force, larger deformation can just occur for the less cushion of modulus of elasticity, and then absorb battery mould
Impulsive force or expansive force that group is subject to.
Cushion, can be set to two, the modulus of elasticity of one of cushion is more than another by comprehensive actual demand
The modulus of elasticity of individual cushion.For example, can be combined HT-800 and two kinds of materials of HT-700, HT-800 is with HT-700
The different foamed silica gel of two kinds of modulus of elasticity, both performances in the range of decrement are stable, and rebound effect is preferable, not by battery core 21
Temperature influence, this two kinds of materials have produced in enormous quantities in the market.
During using single HT-800 materials, the modulus of elasticity of cushion is larger, in the work of battery modules late expansion power
Under, after HT-800 materials are compressed to 70%, HT-800 materials will be unable to be compressed again, and the expansion space in the later stage of battery core 21 can not
It is guaranteed.Assemble battery modules when, only need to slightly be pressurized for battery core 21 provide pretightning force, but be due to battery core 21 thickness and
The dimensional accuracy of the fixed structure piece of battery core 21 is difficult to ensure that, therefore is difficult to the offer effective prestressing force of battery core 21.If using HT-
700 materials, the modulus of elasticity of cushion is smaller, when installing battery modules, can ensure battery core 21 by larger decrement
Precompression, because it can not provide reaction force to battery core 21 for a long time, the load-carrying ability for adding the structural member of battery modules will
Ask.
As shown in figure 3, the modulus of elasticity of the cushion pad 22 obtained using both foams after compound is individually being used all the time
Between the modulus of elasticity of HT-800 and HT-700 cushion pad 22, from the figure 3, it may be seen that the battery modules bullet that the embodiment of the present application is provided
Property modulus is moderate, the requirement of battery modules early stage pretightning force has both been ensure that, while can ensure that battery modules late expansion has again
Enough spaces, i.e. early stage realize that battery core is pre-fixed by the relatively large H-700 of modulus of elasticity decrement, and the later stage passes through H-
800 guarantee expansive forces slowly discharge, it is ensured that apply effective prestressing force to battery core 21, while ensure the uniform force of battery core 21,
More effective protection is provided to battery core 21.
When battery core 21 is set to multiple, in order to improve the structural strength of whole battery modules, fixed frame can also be set
15, at least two battery cores 21 are installed on same fixed frame 15, to form battery core unit, and this battery core unit at least provided with
For two, above-mentioned cushion pad 22 is set between adjacent battery core unit.After adopting the structure, in same battery core unit, phase
Heat-conducting plate 23 can be set between adjacent battery core 21, the heat-conducting plate 23 can use aluminium sheet, and then be produced when battery modules are worked
Raw heat derives.Obviously, the structure sets cushion pad 22 between adjacent battery core unit, can meet the slow of battery modules
Demand is rushed, remaining space can be left to other parts (such as above-mentioned heat-conducting plate 23) again for so that the synthesis of battery modules
Performance is stronger.
The setting form of above-mentioned cushion pad 22 is more various, as shown in figure 4, can will be between adjacent battery core unit it is slow
Rush pad 22 and be set to integral structure, and the edge of cushion pad 22 extends to the edge of battery core 21.That is, adjacent
One cushion pad 22 is only set between battery core unit, and the cushion pad 22 can cover the whole big face of battery core 21 substantially.This
The mode of kind can expand the contact area between cushion pad 22 and battery core 21 as far as possible, optimize the buffering effect of its generation with this.
In another embodiment, at least two cushion pads 22, each cushion pad 22 can be set between adjacent battery core unit
Between have interval.Compared to a upper embodiment, the present embodiment can suitably reduce the contact area of cushion pad 22 and battery core 21,
So that there is heat-dissipating space between adjacent battery core unit, while can make cushion pad 22 is scattered to be covered in battery core 21, and then
Ensure the uniformity of buffering, prevent battery modules from occurring that by-local forces are excessive to ask because the arrangement of cushion pad 22 is uneven
Topic.
Further, as shown in figure 5, can specifically set two cushion pads 22 between adjacent battery core unit, two are delayed
Width of the pad 22 along battery core 21 is rushed to be intervally arranged.Now, cushion pad 22 can use rectangle structure, the cushion pad 22
Length direction it is consistent with the length direction of battery core 21, ensure that cushion pad 22 has enough length with this, and then ensure slow
The active area rushed between pad 22 and battery core 21 is sufficiently large.Certainly, the two cushion pads 22 can also along battery core 21 length
Direction is intervally arranged.
In another structure, as shown in fig. 6, can also set three cushion pads 22 between adjacent battery core unit, this three
Length direction of the individual cushion pad 22 along battery core 21 is intervally arranged.Now, cushion pad 22 can equally use rectangle structure, but
The length direction of cushion pad 22 is consistent with the width of battery core 21 so that each cushion pad 22 can along battery core 21 length
Direction is intervally arranged.In the embodiment, although the length of single cushion pad 22 has reduced compared to a upper embodiment, but the reality
The quantity for applying cushion pad 22 in example is but more than the quantity of cushion pad 22 in a upper embodiment, therefore the embodiment can equally ensure
There is sufficiently large contact area between cushion pad 22 and battery core 21.Certainly, these three cushion pads 22 can also be along battery core 21
Width be intervally arranged.
In other embodiment, each cushion pad 22 constitutes cushion pad group, length side of each cushion pad group along battery core 21 two-by-two
To arrangement, in each cushion pad group, width arrangement of each cushion pad 22 along battery core 21.For example, cushion pad 22 can be set
Four are set to, four cushion pads 22 constitute foregoing cushion pad group two-by-two, it is specific as shown in Figure 7.Certainly, each cushion pad group also may be used
To be arranged along the width of battery core 21, in each cushion pad group, length direction arrangement of each cushion pad 22 along battery core 21.
Several different set-up modes of cushion pad 22 are described above, it is preferable that can be set between battery core 21 and housing
The cushion pad 22 of integral type is put, to obtain larger buffering effect, while can set multiple between adjacent battery core unit
Cushion pad 22, to have buffering and heat-insulated effect concurrently simultaneously.
As shown in figure 8, in a kind of concrete application example, cushion pad 22 uses foam, its original depth is M, battery core 21 and electricity
Gap between core 21 is T1, and the original depth of battery core 21 is T2, the thickness quilt of cushion pad 22 when battery modules are completed
0.8*M (0.8M ＜ T1) is compressed to, now cushion pad 22 is that battery core 21 provides initial pretightning force, when the discharge and recharge of later stage battery core 21
Afterwards, the thickness of battery core 21 increases to 1.1*T2, and the thickness of cushion pad 22 is compressed into 0.2*M, now the life termination of battery core 21,
Because the compression of cushion pad 22 is effectively protected the intensity and stability of the structural member of battery modules, it ensure that well
The stability of battery modules.
In order to reduce the probability that thermal runaway occurs for battery modules, cushion pad 22 (can also not show including aerogel layer in figure
