Referring to fig. 1, fig. 2 and fig. 3, fig. 1 is a schematic structural diagram of a battery 100 according to an embodiment of the present invention, and a single battery 100 provided in an embodiment of the present invention includes a battery core 10, a first connecting member 14 and a second connecting member 20.
The battery cells 10 include at least two, the first connecting members 14 also include a plurality of ones, the plurality of first connecting members 14 correspond to the battery cells 10 one by one, and each of the first connecting members 14 is electrically connected to each of the battery cells 10. Further, the second connecting member 20 also includes a plurality of, and each second connecting member 20 is connected between two adjacent first connecting members 14 in a clamping manner, so that two adjacent first connecting members 14 are connected to each other through the second connecting member 20, and an electrical transmission channel is formed between two battery cells 10 through the second connecting member 20, so as to connect two battery cells 10 together.
In order to facilitate the installation and the disassembly of the second connecting piece 20, the second connecting piece 20 is respectively connected with the two first connecting pieces 14 in a clamped manner, and the first connecting pieces 14 and the second connecting pieces 20 are connected in a clamped manner, so that not only can the number of parts be reduced, but also when one of the battery cells 10 is damaged, the first connecting pieces 14 corresponding to the damaged battery cells 10 are separated from the second connecting pieces 20, so that the damaged battery cells 10 are disconnected from the adjacent battery cells 10, and the damaged battery cells 10 can be detached separately for replacement. Thus, the damaged battery cell 10 can be detached independently by detaching the first connecting piece 14 and the second connecting piece 20, and all the battery cells 10 do not need to be replaced at one time, so that the maintainability of the battery 100 is improved, and the maintenance cost of the battery 100 is greatly reduced.
Above-mentioned battery 100, a plurality of batteries 10 in battery 100 are through first connecting piece 14 and second connecting piece 20 interconnect, and first connecting piece 14 and second connecting piece 20 adopt the mode of joint to link to each other, not only can reduce the quantity of part, can also when one of them battery 10 takes place to damage, will damage first connecting piece 14 and second connecting piece 20 looks mutual separation that battery 10 corresponds, thereby with the mutual disconnection of damaged battery 10 and adjacent battery 10, and then can dismantle the battery 10 of damage alone and come out and change. Thus, the damaged battery cell 10 can be detached independently by detaching the first connecting piece 14 and the second connecting piece 20, and all the battery cells 10 do not need to be replaced at one time, so that the maintainability of the battery 100 is improved, and the maintenance cost of the battery 100 is greatly reduced.
In the embodiment of the present invention, each first connecting element 14 has a clamping portion 11, each second connecting element 20 has two matching portions 21, and each matching portion 21 is clamped with the clamping portion 11 of the adjacent first connecting element 14. When it is necessary to separate the first connecting member 14 and the second connecting member 20, it is only necessary to separate the engaging portion 11 and the fitting portion 21 from each other.
In the embodiment, one of the clamping portion 11 and the matching portion 21 is a bump 22, and the other has a connecting hole 13 matching with the bump 22. When it is necessary to match the engaging portion 21 with the engaging portion 11, the protrusion 22 can be inserted into the connecting hole 13, thereby completing the interconnection of the engaging portion 21 with the engaging portion 11. When two adjacent battery cells 10 need to be removed, the protrusion 22 and the connection hole 13 may be separated, and then the battery cell 10 may be separated from the adjacent battery cell 10, so as to replace the battery cell 10 with a new one.
In some embodiments, the protrusion 22 is in interference fit with the connection hole 13, so that the protrusion 22 is tightly fixed in the connection hole 13, and the connection between the first connection member 14 and the second connection member 20 is also more secure, and the connection between the adjacent battery cells 10 caused by the loose connection of the clamping portion 11 and the matching portion 21 is prevented.
In a preferred embodiment, the fastening portion 11 of the first connecting member 14 has a connecting hole 13, the engaging portion 21 of the second connecting member 20 is a protrusion 22, and when the engaging portion 21 and the fastening portion 11 need to be separated from each other, the protrusion 22 and the connecting hole 13 cannot be easily separated because the protrusion 22 and the connecting hole 13 are in interference fit. For this reason, in the actual use process, when the damaged battery cell 10 needs to be disassembled, a cutting manner is usually adopted to cut off a portion of the bump 22, so as to facilitate the separation of the bump 22 and the connection hole 13 from each other. Since one of the projections 22 of the second connecting member 20 is cut off, the second connecting member 20 needs to be replaced, and for this purpose, the other projection 22 of the second connecting member 20 needs to be separated from the coupling hole 13 of the first connecting member 14. Since the projection 22 is cut away, the connection hole 13 of the first connection member 14 is not affected, and after the new second connection member 20 is replaced, the connection hole 13 of the first connection member 14 can be used for installing the new second connection member 20.
Specifically, if one of the two adjacent battery cells 10 is damaged and the other battery cell 10 functions normally, the damaged battery cell 10 needs to be replaced. For this purpose, the second connecting element 20 is first cut into the projections 22 of the damaged cell 10, so that the second connecting element 20 can be separated from the damaged cell 10. Then, the second connecting member 20 is cut corresponding to the bump 22 of the normal battery cell 10, so that the second connecting member 20 and the normal battery cell 10 are separated from each other, and the cut second connecting member 20 is replaced, and at this time, the connecting hole 13 of the first connecting member 14 on the normal battery cell 10 is intact, and can be connected to a new second connecting member 20 normally. Finally, the damaged battery cell 10 is replaced with a normal battery cell 10, a new second connecting member 20 is selected, and the two matching portions 21 of the new second connecting member 20 are respectively and mutually clamped with the first connecting members 14 of the two normal battery cells 10, so that the damaged battery cell 10 is replaced, and the battery 100 is maintained.
It should be noted that the cross section of the bump 22 may be circular, triangular, or the like, the cross section of the connection hole 13 may be matched with the bump 22, or may be circular, triangular, or the like, and the shapes of the bump 22 and the connection hole 13 may be selected according to actual use requirements, which is not limited herein.
During the actual use of the battery 100, the battery 100 is affected by external factors such as impact or short-circuiting of bubbles, and an excessive current may flow through the battery 100. If the battery cell 10 inside the battery 100 continuously receives an excessive current, the excessive current may cause the battery cell 10 to continuously generate heat until the battery cell 10 burns, which may cause the battery 100 to catch fire.
To this end, in the embodiment of the present invention, at least a portion between the two fitting portions 21 of each of the second connection members 20 is formed as a fusing portion 23 adapted to be fused. When too big electric current second connecting piece 20, fusing part 23 can be because too big electric current process and rapid heating up, if too big electric current lasts always, fusing part 23's temperature can reach fusing part 23's fusing temperature, fusing part 23 just can break off by oneself because the fusing, second connecting piece 20 just can not be connected two adjacent electric cores 10, thereby make too big electric current break off in fusing part 23 department, thereby avoid electric core 10 to continuously withstand the burning that too big electric current and cause, avoid the emergence of battery 100 phenomenon of catching fire, improve battery 100's security.
In some embodiments, the cross-sectional area of the fusing part 23 is smaller than that of each matching part 21, and in actual use, the larger the cross-sectional area of the same length of wire is, the smaller the resistance is, and the larger the current can be borne. Conversely, the smaller the cross-sectional area of the wire, the greater the resistance and the smaller the current that can be sustained. In this way, the cross-sectional area of fusing part 23 is smaller than the cross-sectional area of matching part 21, so that fusing part 23 resistance increases, the current that can be borne decreases, and the heat generated by the excessive current when passing through fusing part 23 increases, so that fusing part 23 can be fused in time when the excessive current occurs, and the safety of battery 100 can be protected quickly.
Further, when the fusing part 23 is fused, the current between the battery cells 10 is cut off, and at this time, the battery 100 may be repaired while the safety of the battery 100 is ensured. Since the fusing part 23 is located on the second connecting member 20, the second connecting member 20 is detachable with respect to the battery cell 10. In this way, after the fusing part 23 is fused, the fused second connecting member 20 may be removed, and then a new second connecting member 20 is replaced, so that the connection between the battery cells 10 may be recovered, thereby recovering the normal operation of the battery 100. In the maintenance process, only the second connecting piece 20 needs to be replaced, and the battery cell 10 does not need to be maintained and replaced, so that the maintenance convenience of the battery 100 is greatly improved. In this manner, by providing the fusing part 23 on the second connector 20, the maintainability of the battery 100 can be further improved while the safety of the battery 100 is ensured.
In the embodiment of the present invention, each battery cell 10 has two terminals 12, which are respectively used as a positive electrode and a negative electrode of the battery cell 10, for this purpose, each battery cell 10 is also provided with two first connecting members 14, and the two first connecting members 14 are respectively electrically connected to the two terminals 12 of the currently located battery cell 10. When the number of the battery cells 10 is two, one of the first connectors 14 of one of the battery cells 10 is connected to one of the first connectors 14 of another one of the battery cells 10, the other first connector 14 of the battery cell 10 serves as a positive electrode or a negative electrode of the battery 100, and the other first connector 14 of the other one of the battery cells 10 serves as a negative electrode or a positive electrode of the battery 100.
When the number of the battery cells 10 is two or more, one of the first connection members 14 on the first battery cell 10 is connected to one of the first connection members 14 on the second battery cell 10 through the second connection member 20, and the other first connection member 14 on the first battery cell 10 is used as a positive electrode or a negative electrode of the battery 100, so that current can flow from one of the first connection members 14 on the first battery cell 10, and then flow into the second battery cell 10 through the other first connection member 14 via the second connection member 20. Further, the other first connecting member 14 on the second battery cell 10 is connected to one of the first connecting members 14 on the third battery cell 10 through the second connecting member 20, so that the current flows into the third battery cell 10 through the other first connecting member 14 on the second battery cell 10, and so on, until one of the first connecting members 14 on the last battery cell 10 is connected to one of the first connecting members 14 on the previous battery cell 10 through the second connecting member 20, and then the other first connecting member 14 on the last battery cell 10 is used as the negative electrode or the positive electrode of the battery 100, so that the plurality of battery cells 10 can be connected to each other to form the battery 100.
In some embodiments, one of the first connectors 14 on the first battery cell 10 is connected to the first connector 14 on the second battery cell 10 through the second connector 20, and the other first connector 14 on the first battery cell 10 is also provided with the second connector 20, one of the matching parts 21 of the second connector 20 is connected to the first connector 14, and the other matching part 21 is located outside the battery cell 10. If a new battery cell 10 needs to be mounted before the first battery cell 10, the first connecting member 14 on the new battery cell 10 and the matching portion 21 located outside may be directly clamped to each other, so that the mounting on the battery cell 10 is completed quickly. If it is not necessary to add a new battery cell 10, the matching portion 21 located outside the battery cell 10 may be used as the positive electrode or the negative electrode of the battery 100, so as to be connected to external electric equipment.
Further, similar to the first cell 10, one of the first connectors 14 on the last cell 10 is connected to the first connector 14 on the previous cell 10 through a second connector 20, the other first connector 14 is provided with a second connector 20, one of the matching portions 21 of the second connector 20 is connected to the first connector 14, and the other matching portion 21 extends out of the cell 10. The protruding fitting portion 21 may be used to attach a new battery cell 10, or may be used as a negative electrode or a positive electrode of the battery 100.
In some embodiments, each first connecting member 14 includes a bottom plate 15 and a side plate 16, the bottom plate 15 is connected to the terminal 12 of the current battery cell 10, and the side plate 16 is provided with a clamping portion 11. The side plate 16 and the bottom plate 15 are connected in a bending mode, and when the bottom plate 15 is welded on the pole 12, the bending angle of the side plate 16 and the bottom plate 15 can be adjusted to adjust the position of the first connecting piece 14 so as to meet the installation requirement of the second connecting piece 20.
Optionally, the base plate 15 is connected to the pole 12 by welding.
It should be noted that, in other embodiments, the first connecting member 14 may also be integrally formed with the currently located battery cell 10, that is, the first connecting member 14 is directly formed on the outer casing of the battery cell 10. In this way, not only the number of parts is reduced, but also the step of welding the first connecting member 14 to the battery cell 10 is reduced, thereby improving the mounting efficiency of the battery cell 10.
An embodiment of the present invention further provides an electric device, which includes the battery 100 in any of the above embodiments, and the electric device may be an electric vehicle, an electric train, an electric bicycle, a golf cart, or another electric vehicle. By using the battery 100, when one of the battery cores of the battery 100 is damaged, the first connecting piece and the second connecting piece corresponding to the damaged battery core are separated from each other, the damaged battery core is detached independently for replacement, all the battery cores do not need to be replaced at one time, the maintainability of the electric device is improved, and the maintenance cost of the electric device is reduced.
The battery cell at least has the following advantages:
