Description

Technical Field

[0001] The utility model relates to the field of energy storage, and in particular to a busbar and an energy storage container. Background Art

[0002] Energy storage containers are integrated energy storage systems developed specifically for the mobile energy storage market. They integrate battery cabinets, a battery management system, and a containerized environmental monitoring system. Energy storage inverters and energy management systems are also integrated according to customer needs. With the growing energy storage market, demand for containerized energy storage systems is also increasing. A single container houses multiple battery clusters, and the external output of the container requires current consolidation from each battery cluster. Furthermore, signal lines also need to be connected to the outside world. Therefore, the design of the output method and structure often requires different designs to meet different needs.

[0003] Existing energy storage systems involve multiple energy storage containers. When multiple energy storage containers are connected in series or parallel, the current lines need to be connected. Therefore, the position of the busbar needs to be raised to facilitate the series and parallel connection of the energy storage containers. However, since the current lines are generally fixed at the bottom of the energy storage container body, the current lines need to be bent when they are connected.

[0004] Bending the current line increases its resistance, which in turn increases energy loss during current transmission. It also increases heat generation, and in severe cases, can damage the line. Simply bending the busbar vertically to avoid bending the current line would result in excessively high costs.

[0005] The above problems are in urgent need of resolution. Utility Model Content

DETAILED DESCRIPTION

[0041] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0042] Example 1, as Figures 1-4As shown, this embodiment provides a busbar 100, comprising: a horizontal portion 110, a vertical portion 120, and an inclined portion 130; one end of the vertical portion 120 is fixedly connected to the horizontal portion 110, and the other end is fixedly connected to the inclined portion 130; the horizontal portion 110 and the vertical portion 120 are arranged perpendicularly; and the inclined portion 130 and the vertical portion 120 are arranged at an obtuse angle. The busbar 100 is formed into a bent shape, divided into a horizontal portion 110, a vertical portion 120, and an inclined portion 130, and the inclined portion 130 and the vertical portion 120 are arranged at an obtuse angle. When the current line 300 is connected, the bending degree can be reduced, thereby reducing the resistance of the current line 300 due to the bending. At the same time, the busbar with an obtuse angle can reduce the size of the busbar and reduce the cost of the busbar compared to the busbar with a right angle.

[0043] In this embodiment, the horizontal portion 110 and the inclined portion 130 are respectively disposed on both sides of the vertical portion 120. In other embodiments, the horizontal portion 110 and the inclined portion 130 are respectively disposed on the same side of the vertical portion 120. The positions of the inclined portion 130 and the horizontal portion 110 are set according to actual usage.

[0044] In order to facilitate fixing of multiple wires on the current line 300 , the inclined portion 130 is provided with multiple sets of fixing members 140 side by side; the fixing members 140 are suitable for fixing the external current line 300 .

[0045] Specifically, the fixing member 140 includes at least one set of fixing bolts 141 and a set of connecting plates 142. The connecting plates 142 are disposed at the bottom of the inclined portion 130. The inclined portion 130 has through-holes corresponding to the fixing bolts 141. The connecting plates 142 have threaded holes corresponding to the through-holes. The fixing bolts 141 pass through the external current line 300 and the inclined portion 130, and are then fixed to the threaded holes of the connecting plates 142. There are two fixing bolts 141. The connection of the current line 300 is secured with dual fixing bolts 141, and a connecting plate 142 is provided to secure the dual fixing bolts 141. When the current line 300 is secured, the dual fixing bolts 141 limit the connecting plates 142, preventing the connecting plates 142 from rotating when the fixing bolts 141 are secured. This also eliminates the need for additional reinforcement to secure the connecting plates 142, facilitating subsequent installation.

[0046] In order to ensure the sealing of the external box body 200, the sealing of the busbar 100 needs to be ensured when the busbar 100 is fixed. In this embodiment, a seal 150 is provided on the horizontal portion 110 where it passes through the external box body 200. The seal 150 includes an upper seal 151 and a lower seal 152; the horizontal portion 110 is provided between the upper seal 151 and the lower seal 152; the upper seal 151 and the lower seal 152 are arranged relative to each other and fixed by fixing bolts 141; the upper seal 151 and the lower seal 152 are provided with side wall fixing holes. The seal 150 is provided to ensure the sealing of the busbar 100 when it passes through the external box body 200. The seal 150 is divided into two parts, the upper seal 151 and the lower seal 152 are assembled by docking, and the fixing holes are opened according to specific needs to complete the fixing of the seal 150. It should be noted that, in order to ensure the fixation of the copper bus bar 100 , corresponding bolts are also provided between the copper bus bar 100 and the sealing member 150 for fixation.

[0047] To ensure the verticality of the vertical portion 120, in this embodiment, a support member 160 is provided between the vertical portion 120 and the external housing 200. One end of the support member 160 is fixed to the vertical portion 120, and the other end is fixed to the external housing 200. The support member 160 ensures the verticality of the vertical portion 120 and supports the busbar 100, thereby increasing the stability of the busbar 100.

[0048] It should be noted that the support member 160 is made of insulating material.

[0049] This embodiment also provides an energy storage container, comprising: a box body 200, a current line 300, and the aforementioned busbar 100; the current line 300 is fixedly mounted at the bottom of the box body 200; the busbar 100 is fixed to the middle and lower portion of the side wall of the box body 200; and the current line 300 is electrically connected to the busbar 100. By forming the busbar 100 into a bent shape, divided into a horizontal portion 110, a vertical portion 120, and an inclined portion 130, wherein the inclined portion 130 is arranged at an obtuse angle to the vertical portion 120, the current line 300 can be connected with a reduced degree of bending, thereby reducing the resistance of the current line 300 due to the bending. Furthermore, compared to a busbar arranged at a right angle, a busbar arranged at an obtuse angle can reduce the size of the busbar and reduce the cost of the busbar.

[0050] In summary, the present invention provides a busbar 100 and an energy storage container, comprising: a horizontal portion 110, a vertical portion 120, and an inclined portion 130; one end of the vertical portion 120 is fixedly connected to the horizontal portion 110, and the other end is fixedly connected to the inclined portion 130; the horizontal portion 110 and the vertical portion 120 are arranged perpendicularly; and the inclined portion 130 is arranged at an obtuse angle to the vertical portion 120. By bending the busbar 100 into a horizontal portion 110, a vertical portion 120, and an inclined portion 130, and the inclined portion 130 is arranged at an obtuse angle to the vertical portion 120, the current line 300 can be connected with less bending, thereby reducing the resistance of the current line 300 due to the bending. At the same time, the busbar with an obtuse angle can reduce the size of the busbar and reduce the cost of the busbar compared to the busbar with a right angle.
