Form the space for accommodating the battery core 10.Battery core 10 is covered by protective plate 20 and protection framework 30.
Referring to figure 4., for example, in above-mentioned cuboid battery core 10, circular battery core 10 1 weeks when protection framework 30, protective frame
Body 30 is set as hollow, and framework 30 is protected to be arranged simultaneously along 10 left side 12 of battery core, leading flank 11, right side and trailing flank
This four face coverings can be divided so that battery core 10 is embedded when protecting in framework 30 on upper surface 13 and lower surface
A piece of protective plate 20 is not set；Multiple protective plates 20 can also be set on upper surface 13, a piece of protection is set on the lower surface
Plate 20；Multiple protective plates 20 can also be set on upper surface 13, multiple protective plates 20 are equally set on the lower surface.In battery core
It, can be by 20 close-packed arrays of multi-disc protective plate, thus being somebody's turn to do battery core 10 when multi-disc protective plate 20 is set on the 10 same face
Face covering.
Protective plate 20 in the present embodiment can be stalloy, that is to say, that the thickness very little of protective plate 20.
In the present embodiment, protective plate 20 can pass through, but be not limited to, and the connection types such as bonding are connected to 10 surface of battery core.
Protective plate 20 is connect with 10 surface of battery core, protective plate 20 is moved according to the state change of battery core 10
It is dynamic.For example, when 10 temperature of battery core is excessively high expand when, protective plate 20 can be mobile with the surface of battery core 10.
Optionally, the protective plate 20 can be bonded by thermally conductive adhesives with battery core 10.The protective plate 20 is to lead
Groove can be set on the protective plate 20 in hot property good high-strength material.
In the present embodiment, material good using heating conduction and high intensity makes protective plate 20, so that protective plate 20
It can also radiate while playing protective action for battery core 10.Groove is set on protective plate 20, increases protective plate 20
Surface area, so that the heat dissipation performance of protective plate 20 is more preferable.
Optionally, the protection framework 30 is integrally formed.
In the present embodiment, make that framework 30 is protected to be integrally formed, so that the stability of protection framework 30 itself is more preferable, so as to
Enough better play the effect of fixed battery core 10.Additionally it is possible to simplify assembling flow path and reduce manufacturing cost.
In the present embodiment, protection framework 30 can also be assembled by muti-piece moulding.
In this implementation, the space for accommodating the battery core 10 that at least two panels protective plate 20 and protection framework 30 are formed can
To be non-confined space, that is to say, that may exist a certain distance on protective plate 20 between the side adjacent with protection framework 30.
In the present embodiment, the material of protection framework 30 can be insulating materials.
Fig. 5 is referred to, optionally, position limiting structure is provided in the protection framework 30, the position limiting structure is for making institute
It states in the accommodation space that battery core 10 is maintained at the protection framework 30 and the protective plate 20 is formed.
For example, it is described protection framework 30 include head and the tail of same size successively connect the first moulding 31, the second moulding 32,
Third moulding 33 and the 4th moulding 34.One side of first moulding 31 extends to form limit knot to 33 direction of third moulding
One article of side of structure, the second moulding 32 extends to form position limiting structure to 34 direction of the 4th moulding.
In the present embodiment, tab 14 can be set in battery core 10.For example, can be incited somebody to action in above-mentioned rectangle battery core 10
Tab 14 is arranged on left side 12.
Optionally, it is arranged in protection framework 30 opposite with the tab 14 of the soft-package battery in the protection framework 30 and opens
Mouth 36, the opening 36 is for the tab 14 to be connect with external circuit.
In the present embodiment, tab 14 is connect by setting opening 36 with external circuit, so that connection external electrical
Road is more convenient.
Optionally, it protects and injecting hole 35 is set in framework 30, between the battery core 10 and the protection framework 30
Inject sizing material.
Injecting hole 35 in the present embodiment is convenient for after battery core 10 is embedded in protection framework 30, in battery core 10 and protective frame
Sizing material is added between body 30.Due to the setting of injecting hole 35, allow sizing material be transferred to from injecting hole 35 elsewhere, with
Make that enough sizing materials can be filled between battery core 10 and protection framework 30, so that the connection between battery core 10 and protection framework 30 is more
Add securely.In addition, sizing material is injected from injecting hole 35, so that the sizing material of injection battery core 10 is all filled in battery core 10 and protection framework 30
Between, so as to save sizing material.
Optionally, the soft-package battery includes the lamination that multi-disc is stacked, and is put down on the soft-package battery with the lamination
At least a piece of protective plate 20 it has been covered each by two capable surfaces, the protection framework 30 is along parallel with the lamination
Surface setting between two surfaces.
For example, when the battery core 10 is the cuboid battery core 10, upper surface 13, the lower surface of battery core 10 are and battery core
10 lamination, two surfaces disposed in parallel, then, the protection framework 30 is along the left side 12, leading flank 11, right side
And trailing flank setting, and left side 12, leading flank 11, right side and trailing flank are covered, on the upper surface 13 of battery core 10
At least a piece of protective plate 20 is set to cover upper surface 13, at least a piece of protective plate 20 is set on the lower surface of battery core 10 to cover
Lower surface.
In the present embodiment, since battery core 10 includes the battery core 10 of multilayer laminated setting, when battery core 10 expands,
The deformation of lamination stacking direction can be bigger, in this way, can be so that protective plate 20 follows battery core 10 mobile.So that anti-in setting
When backplate 20, the whole volume of battery core 10 can be arranged smaller, reduce the volume of battery modules.
Refer to Fig. 6, Fig. 7 and Fig. 8, it is contemplated that soft-package battery in use, may there is a situation where it is excessively high,
In the present embodiment, PTC resistor can be connected in the anode or cathode of the battery core 10.For example, can be in the anode of battery core 10
