Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein.

[0026] This utility model embodiment proposes a battery cell assembly that can directly realize the power insertion and removal of battery cells and the insertion and removal of communication and temperature information acquisition, improve the replacement and maintenance of individual battery cells, simplify cumbersome wiring and wire harness acquisition, and improve the convenience of battery cell installation.
[0027] like Figure 1 As shown, a battery cell group 1 includes at least two battery cells 1, and a battery cell connection structure 2 is provided between two adjacent battery cells 1.
[0028] like Figure 2 As shown, the first end of the battery cell 1 has a first positive terminal 11 and a first negative terminal 12, which are spaced apart. The second end of the battery cell 1 has a second positive terminal 13 and a second negative terminal 14, which are spaced apart. For example, the first end and the second end of the battery cell 1 are opposite ends, which facilitates installation.
[0029] The cell connection structure 2 has a first socket 21 and a second socket 22. The first positive terminal 11 of the cell 1 and the second negative terminal 14 of the adjacent cell 1 are inserted into the first socket 21, and the first negative terminal 12 of the cell 1 and the second positive terminal 13 of the adjacent cell 1 are inserted into the second socket 22. The first socket 21 and the second socket 22 are arranged at intervals.
[0030] The cell connection structure 2 of this utility model connects the positive and negative terminals at one end of two adjacent cells 1 in series, realizing the quick connection and disconnection of the terminals of multiple cells 1, and also realizing the convenience of replacing and maintaining a single cell 1.
[0031] For example, the first socket 21 and the second socket 22 are arranged along the thickness direction of the cell connection structure 2, and the two opposite sides of the cell connection structure 2 are respectively plugged into one end of the two cells 1, so that the size of the cell 1 group after being connected in series is smaller.
[0032] For example, the first positive terminal 11 of the battery cell 1 and the second negative terminal 14 of the adjacent battery cell 1 are interference-fitted with the first socket 21, and the first negative terminal 12 of the battery cell 1 and the second positive terminal 13 of the adjacent battery cell 1 are interference-fitted with the second socket 22.
[0033] When multiple battery cells 1 are connected in series, the first positive terminal 11 of battery cell 1 and the second negative terminal 14 of the adjacent battery cell 1 are inserted into the first socket 21, and the first negative terminal 12 of battery cell 1 and the second positive terminal 13 of the adjacent battery cell 1 are inserted into the second socket 22, so that two battery cells 1 are connected in series and fixed. When it is necessary to remove one of the battery cells 1, the battery cell 1 is pulled out from the battery cell connection structure 2.
[0034] For example, the first positive terminal 11 and the second positive terminal 13 of the battery cell 1 are symmetrical to each other, and the first negative terminal 12 and the second negative terminal 14 of the battery cell 1 are symmetrical to each other, so that multiple battery cells 1 are connected in series and look more aesthetically pleasing.
[0035] For example, the shape of the cross-section of the first socket 21 is adapted to the cross-section of the first positive terminal 11 and the second negative terminal 14, and the shape of the cross-section of the second socket 22 is adapted to the cross-section of the first negative terminal 12 and the second positive terminal 13. This embodiment of the utility model does not specifically limit the shape of the socket, the positive terminal, and the negative terminal. Those skilled in the art can set the shape of the socket, the positive terminal, and the negative terminal as needed. For example, when the positive terminal and the negative terminal are square, the socket is configured as square; when the positive terminal and the negative terminal are cylindrical, the socket is configured as circular.
[0036] For example, cell 1 includes, but is not limited to, prismatic cell 1, cylindrical cell 1 and pouch cell, with prismatic cell 1 being used as an example in the following description.
[0037] like Figure 2As shown, for example, the bottom surface of the square-shell cell 1 is provided with a first positive terminal 11 and a first negative terminal 12, and the top surface of the square-shell cell 1 is provided with a second positive terminal 13 and a second negative terminal 14. The first positive terminal 11, the first negative terminal 12, the second positive terminal 13 and the second negative terminal 14 are all square, and the cell connection structure 2 is a square plate shape, but it can also be set to other shapes as needed.
[0038] When two square-shell cells 1 are connected in series, the first positive terminal 11 on the bottom surface of the upper square-shell cell 1 is inserted into the first socket 21, and the first negative terminal 12 on the bottom surface of the upper square-shell cell 1 is inserted into the second socket 22. After rotating the lower square-shell cell 1 by 180°, the second negative terminal 14 on the top surface of the lower square-shell cell 1 is inserted into the first socket 21, and the second positive terminal 13 on the top surface of the lower square-shell cell 1 is inserted into the second socket 22.
[0039] like Figure 3 As shown, for example, the battery cell connection structure 2 includes an insulating body 23. For example, the insulating body 23 is a square plate. Two slots are spaced apart on the insulating body 23. Each slot is fitted with a conductive part 24. For example, the conductive part 24 can be made of metal, such as copper or aluminum. One conductive part 24 is provided with a first socket 21, and the other conductive part 24 is provided with a second socket 22.
[0040] like Figure 2 As shown, when multiple cells 1 are connected in series, one of two adjacent cells 1 is rotated 180° relative to the other, so that the first positive terminal 11 of cell 1 is opposite to the second negative terminal 14 of its adjacent cell 1, and the first negative terminal 12 of cell 1 is opposite to the second positive terminal 13 of its adjacent cell 1. Then, the two cells 1 are connected in series through a cell connection structure 2.
[0041] For example, the insulating body 23 is provided with a receiving cavity 25, and a data acquisition module is provided in the receiving cavity 25. The data acquisition module is an integrated circuit board, and the data acquisition module is equipped with a communication port and a temperature acquisition port, which simplifies the cumbersome wiring and wire harness acquisition. The communication information and temperature information of the battery cell 1 can be directly obtained from the data acquisition module.
[0042] For example, the data acquisition module is also equipped with the main positive terminal and the main negative terminal of the battery cell 1, which realizes the integration of power plugging and unplugging of the battery cell 1 with communication and temperature information acquisition plugging and unplugging, further improving the convenience of battery cell 1 installation.
[0043] This utility model embodiment also provides a battery, including the above-mentioned battery cell 1 group. The battery of this embodiment simplifies the cumbersome wiring and wire harness acquisition, and can directly realize the power plug-in and communication of battery cell 1, and the temperature information acquisition plug-in integration, improve the replacement and maintenance of a single battery cell 1, and simplify the cumbersome wiring and wire harness acquisition.
[0044] This utility model embodiment also provides an energy storage device, including the above-mentioned battery. The energy storage device of this embodiment can directly realize the insertion and removal of temperature information of the battery cell 1, simplifying the cumbersome wiring and wire harness acquisition.
[0045] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
