[0042] Refer to the following Figures 1 to 11 A battery according to some embodiments of the present application is described.

[0043] Embodiment 1

[0044] See also Figures 1 to 4 As shown, an embodiment of the present application provides a battery, comprising: two battery modules, a first bus bar 3, a second bus bar 4 and a third bus bar 5; wherein the two battery modules are sequentially arranged along a preset direction, and the output electrodes of the two battery modules are arranged opposite to each other. For the convenience of explanation in the following text, the two battery modules are named as a first battery module 1 and a second battery module 2, respectively. The first battery module 1 and the second battery module 2 are both formed with a positive output electrode and a negative output electrode, and are respectively arranged close to the two sides of the corresponding battery module along a direction perpendicular to the preset direction;

[0045] Along a direction perpendicular to a preset direction, a first bus 3 and a second bus 4 are respectively arranged on both sides of the battery module, and two output electrodes with opposite polarities at the first ends of the two battery modules, i.e., the positive output electrode of the first battery module 1 and the negative output electrode of the second battery module 2, or the negative output electrode of the first battery module 1 and the positive output electrode of the second battery module 2, are connected in series through the first bus 3, and two output electrodes with opposite polarities at the second ends of the two battery modules, i.e., the negative output electrode of the first battery module 1 and the positive output electrode of the second battery module 2, are respectively electrically connected to the corresponding second bus 4 and the third bus 5 to realize the lead-out of the output electrodes.

[0046] Of course, not limited to the above, the following structure may also be adopted: the two output electrodes with opposite polarities at the first ends of the two battery modules, that is, the negative output electrode of the first battery module 1 and the positive output electrode of the second battery module 2 are connected in series through the first bus 3, and the two output electrodes with opposite polarities at the second ends of the two battery modules, that is, the positive output electrode of the first battery module 1 and the negative output electrode of the second battery module 2 are respectively electrically connected to the corresponding second bus 4 and the third bus 5, and the specific selection is based on actual needs.

[0047] Based on the structure described above, it can be known that in the present application, the two battery modules are arranged opposite to each other, that is, the side with the output pole is arranged close to each other, and are connected in series. The second bus 4 and the third bus 5 used for lead-out can be led out from the middle position to the end, occupying a small space. Moreover, since the output pole of the battery module is exposed on the side of the battery module, it will not contact the battery management module 9 at all, and there is no need to consider the large interval and insulation structure designed in the prior art to ensure the insulation between the output pole and the battery module, which further improves the space utilization and energy density and reduces the material cost.

[0048] In this embodiment, preferably, Figure 2 As shown, the battery further includes a total positive output electrode 6 and a total negative output electrode 7, and along a preset direction, the total positive output electrode 6 and the total negative output electrode 7 are both arranged at the same end of the first battery module 1 away from the second battery module 2. Of course, it is not limited to this. The total positive output electrode 6 and the total negative output electrode 7 can also be arranged at the same end of the second battery module 2 away from the first battery module 1, which is selected according to actual needs;

[0049] The second busbar 4 is electrically connected to the total positive output pole 6 , and the third busbar 5 is electrically connected to the total negative output pole 7 .

[0050] According to the structure described above, the total positive and negative output electrodes 7 are designed at one end of the total module formed by arranging multiple battery modules, so that the space at the end is concentratedly utilized, and the space occupied is smaller than that of the side.

[0051] In this embodiment, preferably, Figure 2 As shown, the second bus 4 and the third bus 5 both extend along the side of the battery module, and the two are arranged up and down along the height direction of the battery module. While leading out the bus nearby, the space in the height direction is fully utilized, so that the space occupied by the bus is smaller. In addition, there are no electrical components on the side of the battery module, and problems such as short circuits will not occur, which is safer. There is no need to design a structure to avoid electrical components, which helps to reduce the design difficulty and material usage of the bus.

[0052] It should be noted that the total positive output electrode 6 and the total negative output electrode 7 can also be arranged on the side of the total module formed by arranging multiple battery modules, and the specific selection is based on actual needs. However, this structure occupies more space than the structure in this application and has poor integration.

[0053] In this embodiment, preferably, Figures 1 to 4 As shown, the battery further includes a housing 8 , and the two battery modules, the first bus bar 3 , the second bus bar 4 and the third bus bar 5 are all arranged in the housing 8 .

Of course, the structure of the reinforcing member 12 is not limited to this, and can also be a flat plate or other structure, which can be selected according to actual needs.

[0065] In this embodiment, preferably, Figure 2 As shown, the battery further includes an insulating spacer member 11, which is disposed between the two battery modules.

[0066] According to the structure described above, the insulating spacer member 11 plays the role of insulating spacer, avoiding short circuit, and is safer and more reliable.

[0069] Further, preferably, the avoidance groove 114 passes through the side and the top of the insulating spacer component 11. Of course, it is not limited thereto, and the avoidance groove 114 may also only pass through the top of the insulating spacer component 11, which is selected according to actual needs.

[0070] In this embodiment, preferably, Figure 3 and Figure 5 As shown, the insulating spacer member 11 is detachably connected to the top and bottom of the housing 8 along its height direction by a fastening member, i.e., a first fastening member 13 such as a screw or a bolt, so that the insulating spacer member 11 is connected to the housing 8 as a whole, and the overall structural strength is higher and the overall structure is more reliable.

[0071] In this embodiment, preferably, Figures 6 to 8 As shown, the insulating spacer member 11 includes a first insulating spacer member 111 and a second insulating spacer member 112 connected to each other, and a cavity is formed therebetween.
