Description
Technical field
The present invention relates to a kind of housing of battery module, a kind of battery module and one kind with this housing to be used to make
The method for making housing according to the preamble of independent claims and battery module.
Background technology
Battery for electric vehicle is usually made of multiple battery modules, and the battery module is again comprising multiple single
Cell device.The normally so-called pouch battery of these battery units（Pouchzellen）, in the pouch battery, battery
The component of element is surrounded by film that is flexible, being typically constructed of metal.
Now, the most of battery module being commercially capable of providing usually has metal shell, for example made of aluminum
Metal shell, and the module housing being made of plastics is not used now.
Battery module housings for pouch battery are subject to high request in terms of the mechanical stability of the housing, because setting
Pouch battery for such module only shows low mechanical strength.In addition, such module housing should also rise
To the effect of enough electric insulations, and the temperature for the cell device being comprised in the battery module can be adjusted well
Degree.In addition, such module housing also should fix the cell device being included therein to anti-vibration.
In order to adjust the temperature for the cell device being comprised in battery module, the battery module is usually connected to fluid
On cooling device or air cooling equipment.Effective cooling has slowed down the ageing process of the chemical composition of the cell device,
And the service life and intensity of circulation of corresponding cell device are added by this way.Such target for adjusting temperature exists
In, only in predefined temperature range operation be comprised in cell device in the battery module.Thus, for example charging
Period, the heat especially produced during quick charge must be exported effectively from the battery module.It is described pre-
The temperature range of definition depends on the embodiment of the cell device.Accordingly, there exist the cell device being run at normal temperatures,
Such as now common lithium iron cell element.It is however, so-called there is also being used as in the temperature range between 80 and 130 DEG C
The cell device system that medium temperature battery system is run.
In this regard, EP 278 48 69 is disclosed, there is provided a kind of battery module housings, the battery module housings are by two
Half-shell is formed, and is sealed by sealing ring.The battery module housings are made of plastics.In addition, US 2013/0130087
A kind of battery module is disclosed, the intermediate layer of heat transfer is set in the battery module between each cell device.
The content of the invention
A kind of housing of battery module, a kind of battery module with this housing and a kind of use are provided according to the present invention
In the method for the housing and battery module of feature of the manufacture with independent claims characteristic.
This is because, the housing of battery module has casing member according to the present invention, the casing member includes four
Side wall and a bottom surface, and the casing member has opening in region on the top, and multiple cell devices can pass through institute
State the inside that opening is brought to the casing member.The casing member is closed using cap member in itself.The casing member includes
Two housing subcomponents, the housing subcomponent form the casing member together.
Other advantageous embodiments of the present invention are the objects of dependent claims.
It is therefore advantageous that the first and second housing subcomponents form longitudinal half portion of the casing member respectively.This
In the case of, symmetrically implement the first and second housings subcomponent.Housing longitudinal direction half portion is understood to that casing member exists
During vertical orientation two case halfs, the case half point are vertically divided into using the casing member opening pointed up
Do not include one of side wall of the casing member fully.
The advantages of this processing method, is, can not only completely or at least partially automatically carry out housing member
The manufacture of part, additionally it is possible to completely or at least partially automatically assemble cell device for the casing member；And the shell
Body subcomponent refers to very simple or slightly more complex component, and the component need not for example be repaired
（Nachbearbeitung）.Further it is possible that the battery module housings are made to adapt to different sizes in a straightforward manner
Battery types or construct the battery module of the cell device with varying number.This adaptation can manufacture accordingly
In frame in a straightforward manner and pass through simply more mold exchange realize.In addition, by correspondingly determining the housing member
Part is dimensioned such that the thrust adaptation being applied on the cell device of the inside for the battery module housings being thusly-formed.
In addition, it is such as between the housing subcomponent is constructed or between the cap member and the casing member
The connection that can be dismantled when, in a straightforward manner replace monocell be possible.By housing part be provided can
Tearing open property also provides the corresponding recycling of cell device.
Furthermore it is advantageous that housing is made of plastics according to the present invention, because plastics are the raw materials of cost advantages, and
And this raw material allows the use of suitable batch fabrication method.Therefore, it is possible to for example manufacture corresponding shell by Shooting Technique
Body portion.Shell composition is set to adapt to the size of any change in simple method, and it is possible.
A kind of particularly advantageous embodiment according to the present invention, the first housing subcomponent, second housing
The insert that element or the cap member include insert, are especially made of metal.Use the particular advantage of insert
It is, some shell areas there can be abnormal mechanical, electric or thermal property（Verhalten）.If by making
There is such case with insert, then can realize corresponding housing subcomponent or lid in a manner of simple and cost advantages
Element.This is varied more cost advantages than the raw material of corresponding shell composition for some regions that is used for the housing itself.
If using the insert of metal, this insert show naturally than the housing being made of plastics accordingly into
Point the considerably higher capacity of heat transmission in region.This realize position exactly temperature adjustment, for example adjust in the battery module shell
The temperature of the cell device of the inside of body.In addition, the insert of corresponding metal can for example be used in the cap member
The electrical contact for the cell device being arranged in the battery module housings.
In this regard, it is further advantageous that, implement to planar corresponding insert, and the insert is at least at its edge
Possesses empty slot in region at least in part（Aussparung）Or crack（Durchbruch）.Produce by this way and surround institute
State the plastic material of insert and engagement form fit, that also material is connected if necessary of the insert.
In addition, it is advantageous to so implement corresponding insertion element so that it is total relative to the housing subcomponent
Area occupies high area fraction, especially in these regions of the housing subcomponent：The region should in support phase later
, after the cell device of the inside of the housing, at least one cell device in the cell device it is corresponding
Near electric conductor.
