Further, in step S1, predetermine and standardize the route of gluing of electric core and end plate in the battery module, still include the following step before:
s0, confirm 1 model of electric core and 2 models of end plate in the battery module to and the quantity of electric core 1 and end plate 2 in the battery module.
It can be understood that the battery cell 1 and the end plate 2 have different specifications and sizes due to different models, and before glue applying paths of the battery cell 1 and the end plate 2 in the battery module are preset and standardized, the specifications and sizes of the battery cell 1 and the end plate 2 need to be determined, so that the glue applying paths can be preset and standardized better; moreover, the battery module has different quantities of the battery cells 1 due to different design specifications, and even has different quantities of the end plates 2, so that the quantities of the battery cells 1 and the quantities of the end plates 2 in the battery modules with different specifications are required to be confirmed. Electric core 1 is current square platelike lithium ion battery cell among the battery module in this embodiment, apron 2 be with the apron 2 of lithium ion battery cell looks adaptation, the electric core 1 and the end plate 2 of different models have different specification and dimension, electric core 1 is the square platelike lithium ion battery cell of current each model in this embodiment, end plate 2 is with the end plate 2 of electric core 1 looks adaptation model, after electric core 1 and end plate 2's model is confirmed, its concrete specification and dimension just can be clear and definite. In the assembly of the battery module, generally, after a plurality of battery cells 1 are glued side by side, a battery core pack is formed, and then two end plates 2 are glued to both ends of the battery core pack. When two adjacent electric cores 1 are glued, glue is generally applied to the surface of one of the electric cores 1, when the end plate 2 and the electric core 1 are glued, glue is generally applied to the surface of the cover plate 2 facing the electric core 1, and after gluing, only one layer of glue is applied between the electric core 1 and between the electric core 1 and the end plate 2. Therefore, in a general case, there are N electrical cores 1 and two end plates 2 in one battery module, the number of the electrical cores 1 to be glued is N-1, the number of the end plates 2 is two, where N is a positive integer greater than 1, and the specific number of N in this embodiment may be selected according to an actual situation, which is not described herein again. Therefore, the number of the gluing paths 3 to be formed is generally one less than the number of the entire cell 1 and the end plate 2.
Referring to fig. 1 to 4 again, further, in step S1, presetting and standardizing the gluing path 3 of the electric core 1 and the end plate 2 in the battery module includes the following substeps:

For example, the standard gluing path 3 has a uniform path length, and the gluing of each cell 1 or end plate 2 adopts the gluing path 3 with the uniform path length, so that the glue consumption statistics is facilitated. When the glue applying device is applied specifically, the moving speed of the glue applying head and the glue discharging amount in unit time are determined, after the glue applying head applies glue according to the standard glue applying path 3, the path length is clear, and the glue discharging amount for completing glue applying can be rapidly calculated based on the path length.
Preferably, in step S11, a gluing area 100 is preset; the glue area 100 is rectangular to obtain the length and width of the glue area 100. In this embodiment, the glue applying area 100 is rectangular, and the length and width of the glue applying area 100 are the length and width of the rectangle. Here, the gluing area 100 is designed to be a regular rectangle, one is to be adapted to the rectangular plate shape of the battery cell 1, and the other regular rectangle is to facilitate the formation of the regular gluing path 3.
In step S12, according to the length and width of the gluing area 100, gluing is performed on a preset path in the gluing area 100 to form a standard gluing path 3; wherein, the length and width of the gluing path 3 are consistent with the length and width of the gluing area 100. The path of beating glue is preset in beating the gluey regional 100 to reach the purpose of standardizing beating the route 3 of gluing, and will glue the length and width in route 3 and beat the length and the width unanimity in gluey regional 100, so that beat the edge of gluing route 3 and can fill the edge of beating the regional 100 of gluing, guarantee sticky quality.
Preferably, the predetermined path is an N-shaped path. And setting the preset path as an N-shaped path, wherein the finally formed glue applying path 3 is the N-shaped glue applying path 3. The N-shaped structure is formed by 3 straight lines, the shape is regular, the length of the whole glue applying path 3 is easy to calculate, the glue applying head is convenient to move, the length and the width of the N-shaped structure can be easier to match with the glue applying area 100, and the gluing quality can be guaranteed by the aid of middle oblique lines. The length of the N-shape in this embodiment is the length of a straight line, and the width is the width between two straight lines.
Preferably, a standard gluing process is adopted to glue the preset path in the gluing area 100. The standard gluing process can ensure the consistency of gluing each electric core 1 and each end plate 2. The specific gluing process can adopt the existing gluing process, and the moving speed of the gluing head, the glue output amount in unit time and other processes are standard and consistent during gluing, so that the existing gluing head and gluing process can be referred to herein, and are not described herein again.

In this embodiment, the standard database includes the model of the electrical core 1, the glue consumption corresponding to the model of the electrical core 1, the model of the end plate 2, and the glue consumption corresponding to the model of the end plate 2. Preferably, the standard database further comprises the model number of the battery module and the glue consumption corresponding to the model number of the battery module. When a new battery module product of needs volume production, according to selecting 1 model and the quantity of electric core that this battery module is required, the model and the quantity of end plate 2, then just can correspond the corresponding volume of gluing of a battery module of having confirmed according to the mark database, according to the quantity that the volume production was planned, the total volume of gluing has been confirmed fast, later correspond purchase can, so, just the unanimity just can be guaranteed to glue with the used quantity that volume and production used when the new product design of battery module is just definite.
