Plastic film.
Battery module 10 can also include battery bracket 11, and battery cell is set to battery bracket 11, to fix battery list
Body.At this point, the first location structure 111 can be set on battery bracket 11, after such setting, battery bracket 11 can be electricity
Pond monomer provides support, prevents from causing to damage to battery cell excessive compression in 10 installation process of battery module；And battery cell
It is realized and is positioned by battery bracket 11 with end plate 20, also can be avoided location structure and be directly arranged at battery cell to battery cell
It is influenced caused by performance.Wherein, battery bracket 11 can be rectangular frame structure, in order to the regularly arranged shape of each battery module 10
At battery pack, the length direction and width direction of rectangular frame structure can be perpendicular to above-mentioned thickness direction X.
Optionally, battery module 10 further includes shell (not shown), and shell and battery bracket 11 form battery and accommodate
Space, battery cell are contained in the battery accommodating space.Wherein, each battery module 10 can be set one, two or more
The number of multiple battery cells, the battery cell that each battery module 10 is arranged can be equal, can also be unequal.
Specifically, in the first location structure 111 and the second location structure 23, one includes bulge-structure, and another one includes
Limiting slot, bulge-structure are adapted with limiting slot, and by the way of this protrusion and limiting slot, structure is simple, and is easily assembled.
Wherein, the second location structure 23 can be only arranged at body part 21 or insulation division 22, can also be set to simultaneously
Body part 21 and insulation division 22.Preferably, insulation division 22 and body part 21 are provided with the second location structure 23, to realize simultaneously
The positioning of 21 three of battery pack, insulation division 22 and body part prevents insulation division 22 from sending out during battery pack is locked with end plate 20
Raw displacement, reduces the insulation effect of insulation division 22.
When end plate 20 is provided with limiting slot, limiting slot is along the thickness direction penetrating end plates 20 of end plate 20, i.e. limiting slot edge
Thickness direction X penetrates through body part 21 and insulation division 22, to increase the depth of limiting slot, improves the positioning accurate of end plate 20 and battery pack
Degree, and further facilitate the setting of limiting slot；Insulation division 22, body part 21 and battery pack can preferably be determined simultaneously
Position, improves the installation accuracy of battery modules.
The edge of projection of the limiting slot on the thickness direction X of end plate 20 can be enclosed construction, also can be set scarce
Mouth 231, when being arranged jagged 231, limiting slot be can be set in the edge of end plate 20, and one end passes through notch 231 and end plate
20 edge connection, as shown in Figure 3-Figure 5, after such setting, during installation, bulge-structure can be inserted by notch 231
Limiting slot can also be inserted into limiting slot along above-mentioned thickness direction X, so that the flexibility that end plate 20 is matched with battery assembly is increased,
Facilitate the installation of battery modules.
Wherein, above-mentioned limiting slot can be U-type groove, and the opening of U-type groove penetrating end plates 20, U-type groove can be set in end plate
20 edge, to form notch 231；Bulge-structure can be cylindrical body；Certainly, it is rectangular configuration that limiting slot, which may be opening,
Or the slot of other polymorphic structures, as long as bulge-structure is adapted with the slot.
Above-mentioned first location structure 111 and the second location structure 23 can be provided only with one group, in order to improve battery pack with
Multiple groups have also can be set in the positioning accuracy of end plate 20, such as are provided with two groups, three groups etc., wherein two group of first location structure
111 and second in location structure 23, limiting slot and bulge-structure clearance fit in one group, as shown in Figure 4；Limit in another group
Position slot and bulge-structure transition fit, as shown in Figure 5.That is, the opening area of the limiting slot in one group is greater than another group
In limiting slot opening area, as shown in fig. 4-5, limiting slot be U-type groove, bulge-structure be cylindrical body when, along above-mentioned
In the projection of thickness direction X, the diameter of one group of bulge-structure is less than the width of limiting slot, between bulge-structure and limiting slot the two
Gap cooperation, so that there are gaps between bulge-structure and limiting slot；The diameter of another group of bulge-structure and the width of limiting slot
Unanimously.After such setting, in assembly, opening area biggish limiting slot can absorb to be generated in processing and assembling process
Tolerance is easy to the installation of battery modules.Optionally, when limiting slot is U-type groove, it is U-shaped that the width of a U-type groove is greater than another
1.5 times of the width of slot, with preferable absorption processing and build-up tolerance.Wherein, above-mentioned width refers to limiting slot along rectangular frame knot
The size of the length direction of structure.
It should be noted that can also include limiting slot with the first location structure 111, the second location structure 23 includes protrusion knot
Structure.In view of end plate 20 is plate structure, finite thickness, it is preferable that the first location structure 111 includes bulge-structure, protrusion
