Description

Technical Field

[0001] This utility model relates to the field of low-voltage parking air conditioner battery technology, and in particular to a low-voltage parking air conditioner battery output terminal base and battery module. Background Technology

[0002] The current design of low-voltage 24V battery modules generally places the BMS (Battery Management System) on the top cover, and the module output terminals on the end plates on the same side or both sides. For high-current BMS, due to the relatively high overall height, it is placed on the end plate. However, low-voltage 24V parking air conditioning batteries also have strict length limitations. Placing the BMS on the end plate would undoubtedly increase the overall length of the battery. Therefore, neither placing the BMS on the top cover nor on the end plate is suitable for low-voltage 24V parking air conditioning batteries.

[0003] To address the aforementioned technical issues, those skilled in the art would readily recognize that placing the BMS on the side panel of the battery module could solve the size limitation problem. However, if the BMS is placed on the side panel, the module output terminals must be placed on the same side. Since the output terminal base of existing low-voltage 24V battery modules only has one insert nut, the solution of placing the module output terminals on the same side panel is not applicable. Utility Model Content

[0004] In view of this, this utility model proposes a low-voltage parking air conditioning battery output terminal base and battery module. By improving the structure of the output terminal base, the technical problem that the existing output terminal base cannot be used simultaneously when the BMS is set on the side plate is solved.

[0010] In some embodiments, the first insert nut, the second insert nut, and the third insert nut are integrally molded with the positive output electrode base.

[0011] In some embodiments, the fourth insert nut is a second groove structure formed by extending downward from the upper surface of the negative output electrode base.

[0012] In some embodiments, the fourth insert nut and the negative output electrode base are integrally molded injection structures.

[0014] In some embodiments, the wire channel and the positive output electrode base are integrally molded injection structures.

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0036] To address the technical problem that existing battery module output terminal bases cannot accommodate solutions for placing the BMS on the same side panel, this invention improves the structure of the battery module output terminal base and proposes a low-voltage parking air conditioning battery output terminal base.

[0037] like Figures 1-3 As shown, the present invention proposes a low-voltage parking air conditioning battery output terminal base 100, including a positive output terminal base 110 and a negative output terminal base 120. The positive output terminal base 110 has a first insert nut 111, a second insert nut 112, and a third insert nut 113 arranged sequentially. The first insert nut 111 is used to connect to the positive output bus 200, the second insert nut 112 is used to connect to the positive adapter bus 300, and the third insert nut 113 is used to connect to the P connection bus 420 of the BMS device 400. The negative output terminal base 120 has a fourth insert nut 121, which is used to connect the negative output bus and the B connection bus 430 of the BMS device 400.

[0038] Compared with existing output terminal base structures, the output terminal base 100 provided by this utility model is mainly an improvement on the positive output terminal base 110. Specifically, a first insert nut 111, a second insert nut 112, and a third insert nut 113 are sequentially arranged on the positive output terminal base 110 for connection with the positive output bus 200, the positive adapter bus 300, and the P connection bus 420, respectively. Thus, the output terminal base 100 provided by this utility model can meet the requirement of connecting several cables simultaneously, thereby adapting to the requirement of placing the BMS device 400 on the side plate, greatly reducing the height of the assembled battery module, and meeting the size requirements of low-voltage parking air conditioning batteries; moreover, the cable length used is shorter, greatly saving costs.

[0039] In one embodiment, the first insert nut 111, the second insert nut 112 and the third insert nut 113 are all first groove structures formed by extending downward from the upper surface of the positive output electrode base.

[0040] In one embodiment, the first insert nut 111, the second insert nut 112 and the third insert nut 113 and the positive output electrode base 110 are integrally molded injection structures made of low-cost PPE+GF20 material.

[0041] In one embodiment, the fourth insert nut 121 is a second groove structure formed by extending downward from the upper surface of the negative output electrode base.

[0042] In one embodiment, the fourth insert nut 121 and the negative output electrode base 120 are integrally molded injection structures made of low-cost PPE+GF20 material.

[0043] In one embodiment, the positive output base 110 also has a wire passage groove 114, which is disposed between the second insert nut 112 and the third insert nut 113 for fixing the wire.

[0044] In one embodiment, the wire channel 114 and the positive output electrode base 110 are integrally molded injection structures.

[0045] like Figure 3 As shown, this utility model also provides a low-voltage parking air conditioning battery module, including the output terminal base 100 provided by the above-described solution of this utility model, as well as battery cells 500, end plates 600, side plates 700, and BMS devices 400. Multiple battery cells 500 are arranged side-by-side, and two end plates 600 are respectively located outside the two outermost battery cells 500. The end plates 600 are made of extruded profiles and can accommodate multiple battery cells 500 of the same width. They are provided with cable tie fixing holes, module mounting holes, and rivet holes. The positive output terminal base 100... 10 and negative output electrode base 120 are respectively disposed on the top of the two end plates 600; the side plate 700 is made of Q235 material and is manufactured by stamping process. The side plate 700 is riveted to the end plate 600 and can withstand great shear force (i.e. cell expansion force). The two side plates 700 are respectively disposed on both sides of the cell 500. The BMS device 400 is disposed on the outer side of one of the side plates 700. The BMS device 400 is connected to the positive output electrode base 110 and the negative output electrode base 120 respectively through connecting bars.

[0046] In one embodiment, the BMS device 400 includes a BMS 410, a P-connection bar 420, and a B-connection bar 430, with the BMS 410 mounted on a side panel 700 via a bracket.

[0047] In one embodiment, the side plate 700 includes an insulating sheet side plate 710 and a heating film side plate 720. The insulating sheet side plate 710 is disposed on the outer side of the battery cell 500, and the heating film side plate 720 is disposed on the outer side of the insulating sheet side plate 710. The BMS device 400 is disposed on the heating film side plate 720.

[0048] In one embodiment, the battery module further includes foam, with a plurality of foams disposed between every two adjacent battery cells 500 for protecting the battery cells 500.

[0049] In addition, this utility model also includes a CCS device. The CCS device adopts a vacuum forming + wire harness solution. The end of the wire harness has an external communication CAN point, and the strength switch is directly connected to the top cover. When the positive and negative output positions on the same side of the battery module are to be interchanged, the output row of the module can be updated directly on the existing output terminal base. The overall module design achieves low cost and simple structure for interchangeing the positive and negative positions on the same side of the battery.

[0050] In summary, the low-voltage parking air conditioning battery output terminal base and battery module provided by this utility model, by setting a first insert nut, a second insert nut, and a third insert nut on the positive output terminal base, can simultaneously meet the connection requirements of the positive output bus, the positive adapter bus, and the P connection bus of the BMS device. In this way, a scheme to place the BMS device on the side plate can be realized, thereby greatly reducing the height of the battery module to meet the size restrictions of the low-voltage parking air conditioning battery.

[0051] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
