Technical Field
[0001] This utility model relates to the field of energy storage system technology, specifically to the bus assembly structure of the cell sampling structure in an energy storage system. Background Technology
[0002] In energy storage systems or power batteries, CCS refers to the electrical connection and sampling system between battery cells. It is used to connect multiple individual battery cells into a module and simultaneously collect information such as voltage and temperature. A busbar is a metal conductive strip or plate used to collect the current from multiple battery cells, transmitting electrical energy like an electrical bus; it is usually made of copper or aluminum. A vacuum-formed bracket is a plastic bracket made using a vacuum forming process, used to fix components such as the busbar and sampling lines.
[0003] Currently, in energy storage systems, the busbars and sampling lines of the CCS (Cell Sampling System) are fixed together with the vacuum forming bracket. This bracket requires a vacuum forming mold, resulting in high costs, long delivery times, and poor practicality. Therefore, it is essential to design a busbar assembly structure for the cell sampling structure in a more practical energy storage system. Utility Model Content

[0007] According to the above technical solution, a placement groove is provided through the side of the connecting plate, and a conductive plate is inserted in the placement groove. A sampling line extends from one end of the busbar, and one end of the sampling line is connected to the conductive plate.
[0008] According to the above technical solution, a plurality of current sensors are embedded in the connecting plate, the current sensors are electrically connected to the sampling line, and the current sensors are electrically connected to the external energy storage system.
[0009] According to the above technical solution, the connecting plate has a plurality of heat dissipation holes extending through its top and bottom, and the heat dissipation holes are aligned with the conductive plate.
[0010] According to the above technical solution, the connecting plate is made of epoxy resin and the conductive plate is made of copper.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0014] Please see Figure 1-4 The present invention provides a technical solution: a busbar assembly structure for a cell sampling structure in an energy storage system, comprising two busbars 2 arranged in a straight line, with a connecting plate 1 on the top of the busbar 2. The connecting plate 1 is located between each group of busbars 2 and is fixed to the busbar 2. The connecting plate 1 replaces the blister bracket, making the structure simpler and eliminating the need for blister mold processing, thus reducing production costs. Both the busbar 2 and the connecting plate 1 are provided with air holes, and air holes are provided with air buckles 3. The busbar 2 and the connecting plate 1 are fixed to each other by air buckles 3. The busbar 2 and the connecting plate 1 are fixed by air holes, making the connection tight and convenient. A placement slot 7 is provided through the side of the connecting plate 1. A conductive plate 5 is inserted into the placement slot 7. A sampling line 8 is extended from one end of the busbar 2. One end of the sampling line 8 is connected to the conductive plate 5. The conductive plate 5 is flexibly inserted through the placement slot 7. The sampling lines 8 are electrically connected through the conductive plate 5. The conductive plate 5 is electrically connected to the external energy storage system to form a conductive circuit, which can form a conductive path to facilitate sampling. Several current sensors 4 are embedded in the connecting plate 1. The current sensors 4 are electrically connected to the sampling line 8 and the external energy storage system. Since the current sensors 4 are electrically connected to the sampling line 8, they can receive the current signal of the sampling line 8 and transmit the current data to the external control system, which facilitates the detection of the working status of each busbar 2. The connecting plate 1 has several heat dissipation holes 6 running through it from top to bottom. The heat dissipation holes 6 are aligned with the conductive plate 5. The heat dissipation holes 6 dissipate heat from the conductive plate 5 to prevent heat from accumulating inside and causing temperature rise and deformation. The connecting plate 1 is made of epoxy resin, and the conductive plate 5 is made of copper. Copper has good conductivity and can be regarded as a conductor, which facilitates the sampling of the internal current of each busbar 2. The epoxy resin material has good insulation and resistance to temperature deformation, and the material is transparent and easy to observe.
[0015] Instead of using a vacuum forming bracket, a connecting plate is used. The supporting plastic parts in CCS are fastened to the busbar using sheet connecting plates and eyelets. The connecting plate only needs to be drilled and fastened with eyelets to form a simple CCS assembly. It is then welded as a whole into the battery module, avoiding the risk of having to make molds and processes, which is simple and convenient.
