The batteries referred to in the art may be classified into disposable batteries and rechargeable batteries according to whether they are rechargeable or not. Types of rechargeable batteries that are common today are: lead-acid batteries, nickel-metal hydride batteries, and lithium ion batteries. Lithium ion batteries are currently widely used in pure electric vehicles and hybrid electric vehicles, and the lithium ion batteries used for such purposes have relatively low capacity, larger output and charging currents, longer service life and higher cost.

The battery described in the embodiments of the present application refers to a rechargeable battery. Hereinafter, embodiments disclosed in the present application will be described mainly with reference to a lithium ion battery as an example. It should be understood that the embodiments disclosed herein are applicable to any other suitable type of rechargeable battery. The batteries referred to in the embodiments disclosed in this application may be applied directly or indirectly to a suitable device to power the device.

Reference to a battery in embodiments of the present disclosure refers to a single physical module that includes one or more battery cells to provide a predetermined voltage and capacity. The battery cell is a basic unit in the battery, and can be generally divided into: the battery comprises a cylindrical battery monomer, a cuboid battery monomer and a soft package battery monomer. Hereinafter, will be developed mainly around rectangular parallelepiped battery cells. It should be understood that the embodiments described below are also applicable in some respects to cylindrical cells or pouch cells.

The battery monomer comprises a positive pole piece, a negative pole piece, electrolyte and an isolating membrane. The lithium ion battery cell mainly depends on the movement of lithium ions between the positive pole piece and the negative pole piece to work. The film structure of three layers of materials in the cylindrical battery cell is wound into an electrode assembly having a cylindrical shape, and the film structure is wound or stacked into an electrode assembly having a substantially rectangular parallelepiped shape in the rectangular parallelepiped battery cell.

In a typical battery cell structure, a battery cell includes a case, an electrode assembly, and an electrolyte. An electrode assembly is received in the case of the battery cell, the electrode assembly including a positive electrode tab, a negative electrode tab, and a separator. The housing includes a housing and an end cap. The housing includes a receiving cavity formed by a plurality of walls and an opening. An end cap is disposed at the opening to close the receiving cavity. The receiving cavity receives an electrolyte in addition to the electrode assembly. The positive and negative electrode tabs in the electrode assembly include tabs. In order to ensure that the high current can be passed through without fusing, a plurality of positive electrode tabs are stacked together, and a plurality of negative electrode tabs are stacked together. The tab is electrically connected to an electrode terminal located outside the battery cell, which generally includes a positive electrode terminal and a negative electrode terminal, through a connection member. For a rectangular parallelepiped battery cell, the electrode terminals are generally provided at the end cap portions. A plurality of battery cells are connected in series and/or in parallel via electrode terminals to be applied to various applications.

In some high power applications, such as electric vehicles, the application of batteries includes three levels: battery cell, battery module and battery. The battery module is formed by electrically coupling a certain number of battery cells together and putting them in a frame in order to protect the battery cells from external impact, heat, vibration, etc. The battery refers to a final state of a battery system incorporated in the electric vehicle. Batteries generally include a case for enclosing one or more battery cells. The box body generally consists of a cover body and a box shell.

The frame of box or case shell middle part is provided with a plurality of mounting points that are used for being connected with the vehicle main part, for the stability that improves vehicle main part and battery and be connected, sets up mounting portion at mounting point more.

In some battery production and processing technologies, a plurality of battery cells are first integrated into a battery module, and then the battery module is packaged in a battery box to form a battery pack/box.

A typical battery module generally includes two end plates with a plurality of cells disposed therebetween. The end plate on which the output electrode of the battery module is provided is also called an output electrode end plate, and the end plate on which the output electrode of the battery module is not provided is also called a non-output electrode end plate.

The battery pack can be used for packaging a plurality of battery modules in a row and can also be used for packaging a plurality of battery modules in a multi-row mode, and the plurality of battery modules in the multi-row mode can be arranged in double rows and multiple columns, multi-row and double rows, multi-row and multiple columns and the like. Taking a battery pack for packaging double rows and multiple columns of battery modules as an example, the first end plate in each column is generally a head output electrode end plate, two adjacent end plates between two rows of battery modules are middle non-output electrode end plates, the last end plate in each column is a tail non-output electrode end plate, the head output electrode end plate and one of the middle non-output electrode end plates belong to the first row of battery modules, and one of the middle non-output electrode end plates and the tail output electrode end plate belong to the second row of battery modules.

The battery module is packaged in the battery box body by means of a tool, and the tool is generally provided with a clamping mechanism for clamping the battery module, such as a clamping jaw, a sucking disc and the like. When the tooling provided with the clamping jaws is used for packaging the battery module, one side of the end plate, which is far away from the battery monomer, is generally provided with a clamping jaw groove matched with the clamping jaws so that the clamping jaws can be inserted to clamp and transfer the battery module.

The development of battery technology needs to consider various design factors, such as energy density, cycle life, discharge capacity, charge and discharge rate, and other performance parameters, and also needs to consider the production cost and processing technology of the battery to improve the quality and production efficiency of the battery.

The inventor notices that the common output electrode end plate and the non-output electrode end plate are provided with three clamping jaw grooves with the same position, and the clamping jaw grooves are only suitable for mounting battery packs which are positioned at two sides of a box body and are used for packaging a row of a plurality of battery modules. For a battery pack in which the mounting portion is located in the middle of the case and encloses two or more rows of battery modules, the above-described end plate is not suitable. This is because the holding jaw interferes with the mounting portion when inserted into the holding jaw groove of the middle non-output electrode terminal plate. In order to avoid the interference situation, the clamping jaw grooves on the middle non-output pole plates of the battery modules in different rows are distributed differently, and when the battery modules in different rows are packaged into the box body, the clamping jaw tools need to be frequently changed to adapt to the different clamping jaw grooves, so that the production takt is increased, the labor and time costs are increased, and the assembly efficiency of the battery is lower.

Based on the consideration, in order to solve the problem that the assembly efficiency of the battery is low due to frequent replacement of clamping jaw tools, the inventor designs a battery through deep research, the number and the positions of clamping jaw grooves of a head output electrode end plate and a tail output electrode end plate are designed to be the same, the number and the positions of clamping jaw grooves of two middle non-output electrode end plates are designed to be the same, the same tool can be simultaneously adapted to clamping jaw grooves of different rows of battery modules in a mode of rotating the tool by one hundred eighty degrees, the production beat is saved, and the assembly efficiency of the battery is improved.

The technical scheme described in the embodiment of the application is suitable for the battery and the electric equipment using the battery.
