Brief description of the drawings
Fig. 1 is a schematic diagram for implementation method for representing battery pack of the present utility model.
Fig. 2 is the schematic diagram of another implementation method for representing battery pack of the present utility model.
Reference
1 battery pack, 2 thermoinduction material layers, 3 labels
Specific embodiment
Below in conjunction with the accompanying drawings, various implementation methods of the present utility model are described in detail.
Battery pack of the present utility model is provided with thermoinduction material layer on surface, and the thermoinduction material layer is more than 50 DEG C
At a temperature of change colour.Discoloring temperature on the thermoinduction material layer can also be defined to as needed more than 60 DEG C,
More than 70 DEG C or more than 80 DEG C, as long as can change colour in the battery adstante febre that is short-circuited.The color temperature of thermoinduction material layer
Degree is related to the species of thermoinduction material, can select appropriate thermoinduction material to realize required discoloring temperature.
The thermoinduction material layer is set by the surface of battery pack, when battery pack is short-circuited adstante febre, the heat
Inductive material layer can change colour such that it is able to will easily there occurs the battery pack detection of short circuit thermal.
As such battery pack, for example, showing an implementation method in Fig. 1.As shown in figure 1, in the table of battery pack 1
Face is provided with thermoinduction material layer 2.
The thermoinduction material layer 2 can be arranged directly on the surface of battery pack 1.As thermoinduction material layer is direct
The method on the surface of battery pack is arranged on, for example, thermoinduction material can be sprayed directly into battery surface, it is also possible to
Thermoinduction material is made after cream pasty state to be applied to battery surface and dry and is formed.
In addition, the thermoinduction material layer can also be arranged on substrate layer, and the substrate layer sets via adhesive layer
Put on the surface of battery pack.Specifically, thermoinduction material layer can be previously formed in a surface of substrate layer and in institute
Another surface for stating substrate layer forms adhesive layer and is made thermoinduction material membrane, and the thermoinduction material membrane then is pasted into electricity
The surface of pond group.According to such mode, it is avoided that when thermoinduction material layer is set and battery pack is had undesirable effect,
The yield rate of battery pack, improve production efficiency can be greatly improved.
Additionally, showing another implementation method of battery pack of the present utility model in Fig. 2.As shown in Fig. 2 in battery pack
1 surface is provided with label 3, and the surface of the label 3 is provided with the thermoinduction material layer 2.
Present inventor considered that battery pack is generally required for setting label on surface, therefore, according to the mode of Fig. 2, directly
Thermoinduction material layer 2 is arranged on label 3, the Making programme of battery pack can be shortened, effectively improve production efficiency, reduced
Production cost, so as to contribute to industrialized production.
As the label, can be made up of the conventional arbitrary label material that can be used for battery pack.As the mark
The composition of label, generally includes adhesive layer, substrate layer, ink layer.The ink layer is used to be formed the pattern of label.
In the tag, the thermoinduction material layer can be arranged on described in mode not Chong Die with the ink layer
On substrate layer, it is also possible to be arranged on the substrate layer according to the mode Chong Die with the ink layer.
When being formed on the substrate layer according to the mode Chong Die with the ink layer, the thermoinduction material layer can be with
Be arranged on ink layer, it is also possible to be arranged between ink layer and substrate layer, and the thermoinduction material layer inductive material
It is transparent material, to avoid thermoinduction material layer from blocking ink layer.When thermoinduction material layer is arranged on ink layer, it is rising
While whether the effect of short circuit thermal being there occurs to detection battery pack, moreover it is possible to worked as the diaphragm of ink layer, had
Excellent effect.
In the utility model, do not limited especially in the position that the surface of battery pack 1 is set for the thermoinduction material layer 2
It is fixed.But, in order to improve the sensitivity of thermoinduction layer, the thermoinduction material layer 2 is preferably arranged on the side of battery pack
Central portion.The side of battery pack mentioned here refer to battery pack outer surface in the maximum surface of area.
As the thermoinduction material for forming thermoinduction material layer, heat discoloration ink etc. can be included.
As the material for forming substrate layer, heat-sensitive paper etc. can be included.
In the utility model, the species for battery pack is not limited, and can be various battery packs used in the art.
The battery pack has more than one battery.The species of the battery is not particularly limited, and scheme of the present utility model is special
Suitable for secondary cell.
Embodiment
1st, the making of battery pack：
Using 8 making nickel hydrogen battery battery packs of the model of list 4, and in the surface mount label of battery pack, as implementation
Example battery pack.The label includes adhesive layer, the heat-sensitive paper as substrate layer of white, ink layer and positioned at the base successively
Transparent thermoinduction material layer between material layer and the ink layer, the thermoinduction material is made up of heat discoloration ink.
In addition to being not provided with thermoinduction material layer, comparative example has been made identically with the preparation method of embodiment battery pack
Battery pack.
2nd, performance test
It is set to generate heat embodiment battery pack obtained above and the short circuit of comparative example battery pack.Observation can by visual observation
Know, in the label of embodiment battery pack, become red by white.In contrast, comparative example battery is in appearance without any change
Change.
As can be seen here, the utility model sets thermoinduction material layer by battery surface, can easily detect generation
The battery pack of short circuit thermal is crossed, so as to greatly improve the security of battery pack.
