[0002] At present, in the energy storage industry, copper bars have the characteristics of high current and high voltage load. Copper bars are used to connect each battery module in series in the pack box and play a role in connecting and conducting electricity.

[0003] When assembling the pack, usually four copper bars are required. Workers need to install one end of the copper bar on the module first in the limited space at the front end of the pack, and connect the other end to the high-voltage connector or MSD. After arranging the positions of the four copper bars, install them on the front panel. The front panel is equipped with high-voltage plugs and MSDs connected to the copper bars, so that the current inside and outside the pack box forms a loop, and the whole system can operate effectively. However, due to the compact position at the front end of the pack, the four copper bars need to be installed in a certain order and pay attention to the position space. Especially when installing, attention needs to be paid to the installation order and position, otherwise the installation may not be successful. One of the four copper bars is the positive copper bar, and the positive copper bar does not interfere with the other three during the installation process. The installation order of the four copper bars needs to be informed in advance and professional training is provided to the workers; and because the installation process of the other three copper bars is complex and prone to errors, it causes a waste of a large amount of manpower and material resources.

On the basis of this concept, the specific forms and settings of some connection relationships, positional relationships, power mechanisms, power supply systems, hydraulic systems and control systems, etc. may not be fully described. However, on the premise that those skilled in the art understand the concept of the present invention, those skilled in the art can implement the above specific forms and settings in a well-known manner.

[0025] When an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0026] The orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0027] The terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, the meaning of "a plurality" is two or more, and the meaning of "several" is one or more, unless otherwise specifically defined.

[0028] Please refer to Figure 1 and Figure 2 together, and now the three-in-one flexible busbar and energy storage battery provided by the present utility model will be described.

[0029] In a first aspect, the three-in-one flexible copper busbar includes a first flexible copper busbar 1, a second flexible copper busbar 2, and a third flexible copper busbar 3, and the first flexible copper busbar 1, the second flexible copper busbar 2, and the third flexible copper busbar 3 are fixedly connected in sequence along the thickness direction;

[0030] Among them, the lengths of the first flexible copper busbar 1, the second flexible copper busbar 2, and the third flexible copper busbar 3 increase in sequence.

[0031] Furthermore, the first flexible copper busbar 1, the second flexible copper busbar 2, and the third flexible copper busbar 3 are connected to each other through tapes in sequence.

[0032] The first flexible copper busbar 1, the second flexible copper busbar 2, and the third flexible copper busbar 3 are bonded through tapes in sequence. At the same time, the tapes have the property of insulation, so as to insulate and isolate the first flexible copper busbar 1, the second flexible copper busbar 2, and the third flexible copper busbar 3, and avoid short circuits between the adjacent first flexible copper busbar 1, the second flexible copper busbar 2, and the third flexible copper busbar 3 in sequence, which may ultimately cause damage to the battery.

[0033] Specifically, the tape is an acetate cloth tape. The acetate cloth tape is used for the interlayer insulation and bundling of transformers, wire materials, etc.

[0034] The acetate cloth tape is divided into rubber-type acetate cloth and acrylic-type acetate cloth according to the type of adhesive. According to the use requirements of different electrical products, flame retardants need to be added and the base material needs to be treated with flame retardant. The finished product that can achieve self-extinguishing (fireproof) when leaving the fire is "flame-retardant acetate cloth"; the product without adding flame retardants will catch fire immediately when ignited and cannot extinguish automatically, which is "non-flame-retardant acetate cloth tape". Generally speaking, the acetate cloth base material and the adhesive itself cannot prevent fire and need to be specially processed to achieve the "flame-retardant" effect.

[0035] Because the acetate cloth base material has strong moisture absorption and air permeability, good resilience, is easy to wash and dry, does not generate static electricity and lint balls, and has excellent aging resistance performance, which can reach more than 15 years. The acetate cloth tape processed from the acetate cloth base material has the characteristics of high temperature resistance, anti-aging, soft and conformable, good formability, easy die-cutting, easy unrolling, acid and alkali resistance, mildew resistance, etc. Its insulation performance is better than that of general fiberglass cloth and glass cloth, and it is widely used in the manufacturing fields such as televisions, transformers, air conditioners, and computers.

[0036] With the improvement of environmental protection awareness in various countries around the world, customers have continuously put forward new requirements for the environmental protection of acetate cloth. So far, the acetate cloth tape can meet the requirements of Sony SS-00259 standard in the electronics industry, meet the requirements of EU ROHS, meet the requirements of EU REACH, meet the requirements of non-phthalate 6P, and at the same time meet the requirements of halogen-free in the EU, and the product has passed the UL certification.

[0037] Based on the above embodiments, the ends of the first flexible copper busbar 1, the ends of the second flexible copper busbar 2, and the ends of the third flexible copper busbar 3 are all bent.

[0038] Specifically, the first flexible copper busbar 1 is the first connection copper busbar of the MSD, the second flexible copper busbar 2 is the second connection copper busbar of the MSD, and the third flexible copper busbar 3 is the negative output copper busbar; wherein, one end of the first flexible copper busbar 1 is connected to the MSD, and the other end of the first flexible copper busbar 1 is connected to the battery; one end of the second flexible copper busbar 2 is connected to the MSD, and the other end of the second flexible copper busbar 2 is connected to the battery; one end of the third flexible copper busbar 3 is connected to the battery, and the other end of the third flexible copper busbar 3 is connected to the negative high-voltage plug.

[0039] Based on the above embodiments, plastic pipes are sleeved on the middle parts of the first flexible copper busbar 1, the second flexible copper busbar 2, and the third flexible copper busbar 3. The arrangement of the plastic pipes can further enhance the insulation between the first flexible copper busbar 1, the second flexible copper busbar 2, and the third flexible copper busbar 3.

[0040] As a specific embodiment of the present application, a bending portion 31 is provided in the middle of the third flexible copper busbar 3, and the bending portion 31 is used to avoid one end of the second flexible copper busbar 2.

[0041] Specifically, the ends of the first flexible copper busbar 1, the ends of the second flexible copper busbar 2, and the ends of the third flexible copper busbar 3 are arranged at intervals.

[0042] Compared with the prior art, the three-in-one flexible copper busbar provided in this embodiment fixes and connects the first flexible copper busbar 1, the second flexible copper busbar 2, and the third flexible copper busbar 3 together in the thickness direction in sequence. At the same time, plastic pipes are sleeved on the middle parts of the first flexible copper busbar 1, the second flexible copper busbar 2, and the third flexible copper busbar 3, and the ends of the first flexible copper busbar 1, the ends of the second flexible copper busbar 2, and the ends of the third flexible copper busbar 3 are all bent. The originally separate three flexible copper busbars are fixedly combined in a specific order, and the middle parts of the three flexible copper busbars are insulated and the ends are adaptively bent to finally form a three-in-one flexible copper busbar. The design of the three-in-one flexible copper busbar simplifies the training process and operation steps, thereby reducing the error rate and thus reducing the waste of human and material resources.

[0043] In a second aspect, an energy storage battery includes the three-in-one flexible copper busbar involved in the above embodiments.

[0044] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
