[0074] A battery is a power source that provides power to tools, and often refers to the storage or rechargeable battery that powers electric vehicles, electric trains, electric bicycles, and golf carts.

[0075] Multiple batteries are connected to form a cell module. The arrangement of cell modules can increase the energy density of the battery pack, thereby improving the battery life of electrical devices.

[0076] In related technologies, the battery cell module cannot achieve high-current fast charging, resulting in a long charging time for electrical devices and thus low charging efficiency.

[0077] The embodiments of this application provide that multiple battery cells in a battery cell assembly are electrically connected sequentially, which can increase the voltage in the battery cell assembly, thereby increasing the charging power of the battery cell assembly. In multiple battery cell assemblies, adjacent battery cell assemblies are electrically connected, which can increase the current or voltage in the adjacent battery cell assemblies, thereby increasing the charging power of the battery cell assembly. This increases the power of the battery cell module, thereby shortening the charging time of the battery cell module and achieving high-current fast charging.

[0078] like Figures 1 to 2 As shown, the battery cell module 10 provided in the embodiment of this application is used in a battery device 20. The battery cell module 10 includes a plurality of battery cell assemblies 100. Each battery cell assembly 100 includes a plurality of battery cells 101 arranged along a first direction X. Each battery cell 101 has a positive electrode 1011 and a negative electrode 1012 at opposite ends along a second direction Y. The positive electrodes 1011 and negative electrodes 1012 of adjacent battery cells 101 located at the same end are connected in sequence. The positive electrode 1011 of one of the two battery cells 101 located at the end of the first direction X is a positive electrode lead-out 1013 and the negative electrode 1012 of the other is a negative electrode lead-out 1014. Two adjacent battery cell assemblies 100 are connected through the positive electrode lead-out 1013 and the negative electrode lead-out 1014.

[0079] It should be noted that there are several different connection methods between the positive lead 1013 and the negative lead 1014 of two adjacent battery cell assemblies 100. The connection methods between the positive lead 1013 and the negative lead 1014 of two adjacent battery cell assemblies 100 will be illustrated with examples below.

[0080] like Figure 3 As shown, in one feasible implementation, two adjacent battery cell assemblies 100 are connected in series, wherein the positive terminal lead 1013 of the first battery cell assembly 100 and the negative terminal lead 1014 of the second battery cell assembly 100 are electrically connected, or wherein the negative terminal lead 1014 of the first battery cell assembly 100 and the positive terminal lead 1013 of the second battery cell assembly 100 are electrically connected.

[0081] It is understandable that connecting two adjacent cell assemblies 100 in series can increase the voltage of the two adjacent cell assemblies 100, thereby improving the performance of the cell module 10.

[0082] In another feasible implementation, two adjacent cell assemblies 100 are connected in parallel, wherein the positive terminal lead 1013 of the first cell assembly 100 and the positive terminal lead 1013 of the second cell assembly 100 are electrically connected, or wherein the negative terminal lead 1014 of the first cell assembly 100 and the negative terminal lead 1014 of the second cell assembly 100 are electrically connected.

[0083] It is understandable that connecting two adjacent cell assemblies 100 in parallel can increase the current of the two adjacent cell assemblies 100, thereby improving the performance of the cell module 10.

[0084] It is understandable that the specific connection method between the positive lead 1013 and the negative lead 1014 of two adjacent battery cell assemblies 100 is not limited and can be selected according to actual usage requirements.

[0085] It should be noted that, along the second direction Y, the battery cell 101 is provided with a first end face 1017 and a second end face 1018 arranged opposite to each other. The first end face 1017 is provided with a positive electrode 1011 and a negative electrode 1012 that cooperate with each other, and the second end face 1018 is provided with another positive electrode 1011 and another negative electrode 1012 that cooperate with each other.

[0086] It is understandable that the positive electrode 1011 and the negative electrode 1012 are respectively provided on the first end face 1017 and the second end face 1018, which can divert the current to both sides for fast charging, thereby diverting the large current into small currents on both sides to reduce internal resistance and reduce the high temperature generated by the large current fast charging, thereby improving the charging performance of the battery cell 101.

[0087] It should be noted that the battery cell 101 also includes: an outer peripheral wall 1019, a first end face 1017 and a second end face 1018 respectively sealed to the outer peripheral wall 1019 to form a core mounting cavity; wherein a core is provided in the core mounting cavity, and along the second direction Y, each end of the core is provided with at least one positive electrode tab and at least one negative electrode tab, the positive electrode tab and the negative electrode tab at one end of the core are electrically connected to a positive electrode 1011 and a negative electrode 1012 on the first end face 1017 respectively, and the positive electrode tab and the negative electrode tab at the other end of the core are electrically connected to another positive electrode 1011 and another negative electrode 1012 on the second end face 1018 respectively.

[0088] It is understandable that the positive electrode 1011 and negative electrode 1012 of adjacent cells 101 located at the same end can be connected in series. In this way, both ends of the cell assembly 100 along the second direction Y have current flow paths, that is, a cell assembly 100 has dual current flow paths. Compared with the single current flow path of the prior art, it can greatly improve charging efficiency and fast charging performance.

[0089] It should be noted that, along the second direction Y, the negative electrode 1012 on the first end face 1017 and the positive electrode 1011 on the second end face 1018 are arranged opposite to each other, and the positive electrode 1011 on the first end face 1017 and the negative electrode 1012 on the second end face 1018 are arranged opposite to each other, so as to optimize the spatial arrangement of the cell assembly 100 and reduce the connection difficulty of two adjacent cells 101.

[0090] It should be noted that, in the two cells 101 located at the X end in the first direction, the two positive leads 1013 of one of them are connected in parallel to form a total positive lead and the two negative leads 1014 of the other are connected in parallel to form a total negative lead. The two adjacent cell assemblies 100 are connected in series through the total positive lead and the total negative lead.

[0091] like Figure 4 and Figure 5 As shown, it can be understood that by connecting two adjacent battery cell assemblies 100 in series through the total positive lead and the total negative lead, the voltage of the two adjacent battery cell assemblies 100 can be increased, thereby increasing the voltage in the two adjacent battery cell assemblies 100 and thus increasing the charging power of the battery cell assembly 100.

[0092] It should be noted that the total positive lead is configured as a total positive lead 1015, and the total negative lead is configured as a total negative lead 1016. The adjacent total positive leads 1015 and total negative leads 1016 of two adjacent cell assemblies 100 are electrically connected so that the two adjacent cell assemblies 100 are connected in series.

[0093] It is understandable that the adjacent positive lead 1015 and negative lead 1016 of two adjacent cell assemblies 100 are electrically connected to connect the two adjacent cell assemblies 100 in series, which can reduce the connection difficulty of the two adjacent cell assemblies 100, thereby reducing the connection difficulty of the cell module 10 and improving the installation efficiency of the cell module 10.

[0094] It should be noted that there are several different connection methods between the adjacent positive leads 1015 and negative leads 1016 of two adjacent battery cell assemblies 100. The connection methods between the adjacent positive leads 1015 and negative leads 1016 of two adjacent battery cell assemblies 100 will be illustrated below.

[0095] In one feasible implementation, in two adjacent cell assemblies 100, the total positive lead 1015 of one cell assembly 100 and the total negative lead 1016 of the other cell assembly 100 are connected by welding.

[0096] It is understandable that welding the adjacent positive lead 1015 and negative lead 1016 can reduce the connection difficulty between the positive lead 1015 and the negative lead 1016, and can improve the connection strength between the positive lead 1015 and the negative lead 1016, thereby improving the installation efficiency of the battery cell module 10 and extending the service life of the battery cell module 10.

[0097] like Figure 6 and Figure 7As shown, in another feasible embodiment, in two adjacent cell assemblies 100, the total positive lead 1015 of one cell assembly 100 and the total negative lead 1016 of the other cell assembly 100 are connected by screws.

[0098] It is understandable that screwing together the adjacent positive lead 1015 and negative lead 1016 can reduce the connection difficulty between the positive lead 1015 and the negative lead 1016, and can improve the installation efficiency between the positive lead 1015 and the negative lead 1016, thereby improving the installation efficiency of the battery cell module 10.

[0099] In addition, in another feasible embodiment, in two adjacent cell assemblies 100, the total positive lead 1015 of one cell assembly 100 and the total negative lead 1016 of the other cell assembly 100 are connected by adhesive bonding.

[0100] It is understandable that bonding the adjacent positive lead 1015 and negative lead 1016 can reduce the connection difficulty between the positive lead 1015 and the negative lead 1016, thereby improving the installation efficiency of the cell module 10.

[0101] It is understandable that the specific connection method between the adjacent positive lead 1015 and negative lead 1016 of two adjacent battery cell assemblies 100 is not limited and can be selected according to actual usage requirements.

[0102] It should be noted that both the total positive lead 1015 and the total negative lead 1016 include a lead 200 and a parallel connector 201. One end of the parallel connector 201 of the total positive lead 1015 is connected to a positive lead 1013, and the other end is connected to the lead 200 of the total positive lead 1015. The lead 200 of the total positive lead 1015 is connected in parallel with another positive lead 1013; the parallel connector 201 of the total negative lead 1016... One end of the connector 201 is connected to a negative lead 1014 and the other end is connected to the lead 200 of the total negative lead 1016. The lead 200 of the total negative lead 1016 is connected to the other negative lead 1014 in parallel. The leads 200 of the adjacent total positive leads 1015 of two adjacent cell assemblies 100 are electrically connected to the leads 200 of the total negative leads 1016 so that the two adjacent cell assemblies 100 are connected in series.

[0103] It is understandable that one end of the parallel connector 201 of the main positive lead 1015 is connected to a positive lead 1013 and the other end is connected to the lead 200 of the main positive lead 1015. The lead 200 of the main positive lead 1015 is connected in parallel with another positive lead 1013, so that the two positive leads 1011 arranged opposite to each other in the cell 101 can be connected in parallel to increase the current of the cell module 10, thereby improving the performance of the cell module 10. One end of the parallel connector 201 of the main negative lead 1016 is connected to a negative lead 1014 and the other end is connected to the lead 200 of the main negative lead 1016. The lead 200 of the main negative lead 1016 is connected in parallel with another negative lead 1014, so that the two negative terminals 1012 arranged opposite to each other in the cell 101 can be connected in parallel to increase the current of the cell module 10, thereby improving the performance of the cell module 10.

[0104] like Figure 15 As shown, the battery cell module 10 provided in the embodiments of this application further includes: a series connector 202, the series connector 202 includes a series connection portion 2021, and a first connection portion 2022 and a second connection portion 2023 are connected to both ends of the series connection portion 2021 along its length direction. The first connection portion 2022 and the second connection portion 2023 located at the same end are respectively connected to two positive leads 1013 of one of the two adjacent battery cell assemblies 100, and the first connection portion 2022 and the second connection portion 2023 located at the other end are respectively connected to two negative leads 1014 of the other of the two adjacent battery cell assemblies 100.

[0105] It is understandable that the series connector 202 can reduce the connection difficulty between two adjacent cell assemblies 100, thereby improving the installation efficiency of the cell module 10, and can also reduce the space occupied between two adjacent cell assemblies 100, and improve the performance of the cell modules 10 at both ends, thereby increasing the energy density of the cell module 10.

[0106] The battery cell module 10 provided in the embodiments of this application also includes a plurality of parallel connectors 201. One parallel connector 201 is connected between a positive lead 1013 and a second connection portion 2023, and another parallel connector 201 is connected between a negative lead 1014 and another second connection portion 2023.

[0107] Understandably, the arrangement of the parallel connector 201 can reduce the parallel connection between the two ends of a cell 101 to increase the internal current of a cell 101, thereby increasing the energy density of the cell module 10.

[0108] It should be noted that a battery cell assembly 100 is provided with two parallel connectors 201. Along the first direction X, the two parallel connectors 201 are located at both ends of a battery cell assembly 100 to reduce the space occupied by a battery cell assembly 100.

[0109] The second connecting portion 2023 and the series connecting portion 2021 provided in the embodiments of this application are arranged at an angle, and the two second connecting portions 2023 and the series connecting portion 2021 surround to form a mounting groove. The mounting groove is used to install the series connector 202 on the partition beam 21 of the battery device 20.

[0110] Understandably, the partition beam 21 is used to separate two adjacent battery cell assemblies 100, so that the two adjacent battery cell assemblies 100 are spaced apart. The two second connecting portions 2023 and the series connecting portion 2021 form an installation groove, which allows the partition beam 21 to guide the installation of the two connecting portions and the series connecting portion 2021, thereby reducing the installation difficulty of the two adjacent battery cell assemblies 100. Moreover, the partition beam 21 can support the two connecting portions and the series connecting portion 2021, thereby improving the connection strength between the two adjacent battery cell assemblies 100.

[0111] The battery cell module 10 provided in the embodiments of this application further includes: an insulating member 300, which covers the series connection portion 2021 and / or part of the second connection portion 2023.

[0112] Understandably, the insulating component 300 is used to provide safety protection for the series connection portion 2021 and / or part of the second connection portion 2023, so as to reduce the occurrence of conductive connection between the series connection portion 2021 and / or part of the second connection portion 2023 and the separator beam 21, thereby providing leakage protection for the battery cell module 10.

[0113] It should be noted that the insulating component 300 has a variety of different installation positions, and the installation positions of the insulating component 300 will be illustrated with examples below.

[0114] In one feasible implementation, the insulating element 300 covers the series connection portion 2021 so that the series connection portion 2021 and the partition beam 21 can be insulatedly connected, thereby improving the safety performance between the series connection portion 2021 and the partition beam 21.

[0115] In another feasible embodiment, the insulating element 300 covers a portion of the second connection 2023 so that the second connection 2023 and the partition beam 21 can be insulatedly connected, thereby improving the safety performance between the portion of the second connection 2023 and the partition beam 21.

[0116] In addition, in another feasible embodiment, the insulating member 300 covers the series connection portion 2021 and part of the second connection portion 2023 so that the series connection portion 2021 and part of the second connection portion 2023 can be insulatedly connected to the partition beam 21, thereby improving the safety performance between the series connection portion 2021, part of the second connection portion 2023 and the partition beam 21.

The limiting portion 601 is located on the side of the first conductive member 501 or the second conductive member 502 away from the mounting groove, which can reduce interference between the limiting portion 601 and other components on the insulating frame 600, thereby improving the safety performance of the battery cell module 10.
