Detailed Implementation

[0058] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0059] In the description of this disclosure, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this disclosure, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0060] The battery side plate 13, the electrode core assembly 700, the battery 1000, the energy storage device 2000, and the electrical device 3000 according to embodiments of the present disclosure are described in detail below with reference to Figures 1-19.

[0061] Referring to Figures 1-7, the battery side plate 13 according to the embodiment of the present disclosure includes a chip fixing hole 14 and a component passage 130. The chip fixing hole 14 is used to accommodate a chip 403. The chip 403 is used to collect signals in the accommodating cavity 11 of the battery housing 100. The component passage 130 is connected to the chip fixing hole 14 and is used to accommodate a chip connector 400c.

[0062] In other words, the battery side plate 13 is provided with a chip fixing hole 14 and a component passage 130. The chip fixing hole 14 is used to accommodate the chip 403. The chip fixing hole 14 reserves space for the subsequent implantation of the chip 403. The chip 403 is used to collect signals in the receiving cavity 11 of the battery housing 100. The component passage 130 is used to accommodate the chip connector 400c. The component passage 130 is connected to the chip fixing hole 14. The component passage 130 reserves space for the subsequent installation of the chip connector 400c, thereby avoiding the occurrence of phenomena such as squeezing and breakage of the chip connector 400c.

[0063] The mounting position of chip 403 in this disclosure depends on the location of the chip mounting hole 14 on the battery side plate 13. The battery side plate 13 can be positioned at the desired location, thereby allowing for effective monitoring of relevant parameters at that location, with flexible monitoring options. Furthermore, the mounting of chip 403 within the chip mounting hole 14 does not cause any changes to the structure or position of other components surrounding the battery side plate 13.

[0064] When chip 403 is installed in chip fixing hole 14 and chip connector 400c is installed in component channel 130, chip 403 and chip connector 400c can be stably fixed on battery side plate 13. Chip 403 and chip connector 400c will not move or misalign, and further avoid the situation where chip 403 and chip connector 400c are squeezed and deformed by other component structures (such as electrode core 600) around battery side plate 13.

[0065] According to the battery side plate 13 of the present disclosure, the battery side plate 13 is provided with chip fixing holes 14 and component passage 130, which can realize the installation of chip 403 and chip connector 400c on the battery side plate 13. By placing the battery side plate 13 in a suitable position, the relevant parameters at that position can be effectively monitored, and the monitoring position is more flexible.

[0066] In some embodiments of this disclosure, the battery side plate 13 has a first side surface 16 and a second side surface 17, which are arranged back-to-back. The chip fixing hole 14 and the component passage 130 are both located on the first side surface 16, and both the chip fixing hole 14 and the component passage 130 are recessed towards the second side surface 17. This helps to reduce the total height of the battery side plate 13, the chip 403, and the chip connector 400c. For example, as shown in FIG2, the first side surface 16 is the right side surface of the battery side plate 13, and the second side surface 17 is the left side surface of the battery side plate 13. The chip fixing hole 14 and the component passage 130 are both located on the right side surface of the battery side plate 13, and both the chip fixing hole 14 and the component passage 130 are recessed towards the left side surface of the battery side plate 13. In this way, both the chip mounting hole 14 and the component passage 130 are recesses. After the chip 403 is installed in the chip mounting hole 14 and the chip connector 400c is installed in the component passage 130, the total height of the battery side plate 13, the chip 403, and the chip connector 400c will not be too high. For example, when the thickness of the chip 403 is less than the depth of the chip mounting hole 14 and the thickness of the chip connector 400c is less than the depth of the component passage 130, as shown in Figure 5, after the chip 403 is installed in the chip mounting hole 14 and the chip connector 400c is installed in the component passage 130, the chip 403 and the chip connector 400c will not exceed the first side surface 16 of the battery side plate 13, and the total height of the battery side plate 13, the chip 403, and the chip connector 400c is equal to the thickness of the battery side plate 13. When the thickness of chip 403 is greater than the depth of chip fixing hole 14 or the thickness of chip connector 400c is greater than the depth of through channel 130, the total height of battery side plate 13, chip 403, and chip connector 400c is the sum of the thickness of battery side plate 13 and the height of chip 403 and chip connector 400c extending beyond the first side 16 of battery side plate 13.

[0067] In some embodiments of this disclosure, the battery side plate 13 is further provided with a through hole 15. The through hole 15 extends through the first side surface 16 and the second side surface 17 along the thickness direction of the battery side plate 13. The through hole 15 is adapted to be evenly separated from the chip fixing hole 14 and the through-part channel 130. The through hole 15 connects the two sides of the battery side plate 13. When the battery side plate 13 is used as part of the battery casing 100 of the battery 1000, the through hole 15 of the battery side plate 13 enables the interior of the battery 1000 to communicate with the exterior. That is, the through hole 15 provides an exhaust channel to facilitate the exhaust of gas inside the battery 1000.

[0068] In some embodiments of this disclosure, there are multiple through holes 15, each with a diameter d1 ranging from 0.1cm to 1cm. Multiple through holes 15 can improve the airflow efficiency on both sides of the battery side plate 13. When the diameter of the through hole 15 is less than 0.1cm, the diameter is too small, making it difficult for air to flow through the through hole 15 on both sides of the battery side plate 13. When the diameter of the through hole 15 is greater than 1cm, the airflow on both sides of the battery side plate 13 is too large, affecting the pressure maintenance on one side of the battery side plate 13. Furthermore, the large-diameter through hole 15 significantly weakens the strength of the battery side plate 13, leading to a decrease in the strength of the battery side plate 13. Optionally, the diameter d1 of each through hole 15 can be 0.1cm, 0.3cm, 0.5cm, 0.7cm, 0.9cm, 1cm, etc. Of course, the diameter d1 of each through hole 15 can also be other values ​​between 0.1cm and 1cm, which will not be listed here.

[0069] Alternatively, the shape of the through hole 15 can also be designed as a circle, ellipse, rectangle, square, or other polygonal shapes. The diameter d1 of the through hole 15 refers to the equivalent diameter of the through hole 15, that is, the maximum distance between any two points on the through hole 15 is d1.

[0070] Optionally, the number of through holes 15 can be between 8 and 28. For example, the number of through holes 15 can be 8, 10, 16, 20, 24, 28, etc. Of course, the number of through holes 15 can also be other integer values ​​between 8 and 28, which will not be listed here.

[0071] In some embodiments of this disclosure, referring to Figures 1 and 2, the length, width, and thickness of the battery side plate 13 satisfy at least one of the following ranges: the length L1 of the battery side plate 13 ranges from 1cm to 100cm; the width W1 of the battery side plate 13 ranges from 0.1cm to 5cm; and the thickness H1 of the battery side plate 13 ranges from 0.1cm to 1cm. For example, the length L1 of the battery side plate 13 can be 1cm, 10cm, 30cm, 50cm, 70cm, 90cm, 100cm, etc. Of course, the length L1 of the battery side plate 13 can also be other values ​​between 1cm and 100cm, which will not be listed here. The width W1 of the battery side plate 13 can be 0.1cm, 1cm, 2cm, 3cm, 4cm, 5cm, etc. Of course, the width W1 of the battery side plate 13 can also be other values ​​between 0.1cm and 5cm, which will not be listed here. The thickness H1 of the battery side plate 13 can be 0.1cm, 0.3cm, 0.5cm, 0.7cm, 0.9cm, 1cm, etc. Of course, the thickness H1 of the battery side plate 13 can also be other values ​​between 0.1cm and 1cm, which will not be listed here. Typically, the thickness H1 of the battery side plate 13 is much smaller than the length L1 and width W1 of the battery side plate 13, making the battery side plate 13 a flat plate. This results in a thinner and lighter battery side plate 13. When the battery side plate 13 is applied to the battery casing 100 of the battery 1000, the battery 1000 has good heat dissipation, which also helps to achieve a lightweight design of the battery 1000.

[0072] In some embodiments of this disclosure, referring to Figures 1 and 2, the length, width, and depth of the chip mounting hole 14 satisfy at least one of the following ranges: the length L2 of the chip mounting hole 14 ranges from 0.2cm to 3cm; the width W2 of the chip mounting hole 14 ranges from 0.2cm to 2cm; and the depth H2 of the chip mounting hole 14 ranges from 0.1cm to 0.8cm. For example, the length L2 of the chip mounting hole 14 can be 0.2cm, 1cm, 1.5cm, 2cm, 2.5cm, 3cm, etc. Of course, the length L2 of the chip mounting hole 14 can also be other values ​​between 0.2cm and 3cm, which will not be listed here. The width W2 of the chip mounting hole 14 can be 0.2cm, 0.8cm, 1cm, 1.2cm, 1.6cm, 2cm, etc. Of course, the width W2 of the chip mounting hole 14 can also be other values ​​between 0.2cm and 2cm, which will not be listed here. The depth H2 of the chip mounting hole 14 can be 0.1cm, 0.3cm, 0.5cm, 0.7cm, 0.8cm, etc. Of course, the depth H2 of the chip mounting hole 14 can also be other values ​​between 0.1cm and 0.8cm, which will not be listed here. Usually, the depth H2 of the chip mounting hole 14 is less than the length L2 and width W2 of the chip mounting hole 14, so that the chip mounting hole 14 is formed as a flat groove. In this way, the chip mounting hole 14 will not penetrate through the battery side plate 13 along the thickness direction of the battery side plate 13.

[0073] Optionally, the shape of the chip mounting hole 14 can be designed as a circle, ellipse, rectangle, square or other polygonal shape according to the size of the customized chip 403.

[0074] In some embodiments of this disclosure, referring to Figures 1-2 and 4-5, there is one chip fixing hole 14, and the through-hole 130 includes a first channel 131 and a second channel 132. Both the first channel 131 and the second channel 132 are connected to the chip fixing hole 14, but are separate from each other. The first channel 131 and the second channel 132 can lead out and fix the chip connector 400c of the chip 403 in the chip fixing hole 14, which helps to avoid the chip 403 and its chip connector 400c from being squeezed and deformed by the electrode core 600. The first channel 131 and the second channel 132 can allow chip connectors 400c of different electrodes to pass through. For example, the chip connector 400c includes a positive electrode 401 and a negative electrode 402. The first channel 131 allows the positive electrode 401 to pass through, and the second channel 132 allows the negative electrode 402 to pass through, thereby preventing the positive electrode 401 and the negative electrode 402 from interfering with each other.

[0075] In some embodiments of this disclosure, the first channel 131 is connected to one end of the chip mounting hole 14, and the second channel 132 is connected to the other end of the chip mounting hole 14. Both the first channel 131 and the second channel 132 extend away from the chip mounting hole 14. The first channel 131 and the second channel 132 are located on the same straight line. For example, both the first channel 131 and the second channel 132 extend along the length direction of the battery side plate 13. As a result, the width W1 of the battery side plate 13 can be smaller. Furthermore, the positive electrode 401 in the first channel 131 and the negative electrode 402 in the second channel 132 are led out from opposite directions, further reducing the probability of interference between the positive electrode 401 and the negative electrode 402.

[0076] In some embodiments of this disclosure, referring to Figures 6-7, there are multiple chip mounting holes 14. The through-channel 130 includes a first channel 131, a second channel 132, and an intermediate channel 133. Adjacent chip mounting holes 14 are connected through the intermediate channel 133. The first channel 131 is connected to one of the chip mounting holes 14, and the second channel 132 is connected to the other chip mounting hole 14. The intermediate channel 133 is used to accommodate a chip connector 400c that connects the chips 403 in the two adjacent chip mounting holes 14. For example, the chip connector 400c includes a series connector 404, a positive electrode 401, and a negative electrode 402. The series connector 404 is disposed in the intermediate channel 133 and is used to connect the chips 403 in the two adjacent chip mounting holes 14, so that the chips 403 in the two adjacent chip mounting holes 14 are connected in series. The chip 403 in one chip mounting hole 14 is connected to the positive electrode 401, and the chip 403 in the other chip mounting hole 14 is connected to the negative electrode 402.

[0083] Referring to Figures 13-15, the electrode assembly 700 according to a second aspect embodiment of this disclosure includes: an electrode 600 and a battery side plate 13 as described in the above embodiment. The battery side plate 13 is attached to the electrode 600, and the through-hole 130 and the chip fixing hole 14 are located on the side of the battery side plate 13 facing the electrode 600. That is, the first side 16 of the battery side plate 13 faces the electrode 600, which makes the chip 403 mounted in the chip fixing hole 14 closer to the electrode 600, and the detection results can more accurately reflect the true condition of the electrode 600.

[0084] In some embodiments of this disclosure, the electrode assembly 700 further includes a protective film that covers the electrode 600 and the battery side plate 13. That is, after the battery side plate 13 is attached to the electrode 600, the protective film is used to cover the electrode 600 and the battery side plate 13, thereby protecting the electrode 600 and the battery side plate 13.

[0085] Depending on the monitoring requirements, the battery side plate 13 can be positioned at different locations within the electrode core 600. The chip 403 can be fixed in the chip fixing hole 14 of the battery side plate 13, thereby expanding the monitoring range of the chip 403, rather than being limited to the vicinity of the cover plate 2, and without causing changes to the structure and position of other components within the accommodating cavity 11. Simultaneously, the chip 403, through its connection with the accommodating cavity 11 via the chip fixing hole 14, can monitor the state changes of the electrode core 600 in real time, improving the accuracy of early warnings.

[0086] When chip 403 is fixed in chip fixing hole 14, chip 403 can be stably fixed on the surface of electrode core 600. Chip 403 will not move or misalign, and further avoids situations such as chip 403 being squeezed and deformed by electrode core 600.

[0087] The chip mounting hole 14 is a recessed hole extending from the first side 16 to the second side 17, allowing it to communicate with the receiving cavity 11. This reduces the complexity of the processing steps and production of the chip mounting hole 14, improves product quality, and also reduces the difficulty of installing and removing the chip 403 within the chip mounting hole 14. The component passage channel 130 is a recessed channel extending from the first side 16 to the second side 17, allowing it to communicate with the receiving cavity 11. This also reduces the complexity of the processing steps and production of the component passage channel 130, improves product quality, and also reduces the difficulty of installing and removing the chip connector 400c of the chip 403 within the corresponding channel.

[0088] According to the electrode core assembly 700 of this disclosure, the battery side plate 13 of the electrode core assembly 700 can expand the installation space of the chip 403, improve the stability and reliability of the chip 403 fixation, and also improve the convenience of the chip 403 installation operation, without causing changes to the structure and position of other components in the accommodating cavity 11. The chip 403 is fixed in the chip fixing hole 14. The position of the battery side plate 13 is designed according to the monitoring requirements, so that when the chip 403 is placed at different positions on the surface of the electrode core 600, the chip 403 can effectively monitor the changes in temperature, pressure, gas and stress at different positions, monitor the state changes of the electrode core 600 in real time, improve the accuracy of early warning, and extend the response and handling time to dangers. When the electrode core assembly 700 is applied to the battery 1000, it is beneficial to improve the safety of the battery 1000.

The first side plate 141 and the second side plate 142 are disposed opposite to each other, and the third side plate 143 and the fourth side plate 144 are disposed opposite to each other. The width of each of the third side plate 143 and the fourth side plate 144 is greater than the width of each of the first side plate 141 and the second side plate 142. It is understood that the plate width referred to here refers to the dimension of the corresponding plate in the left-right direction in Figure 10.

[0091] Referring to Figures 10-12, the housing body 1 is processed. First, the edges of the housing body 1 are partially bent. Referring to Figure 11, the partial bending of the edges of the housing body 1 is completed. Referring to Figure 12, bending is performed along both sides of the first side plate 141. Finally, the housing body 1 is welded using a laser, that is, the heat generated by the laser beam bombarding the workpiece melts the aluminum at the weld 1421 to achieve welding. After welding, some weld scars are scraped smooth to make the weld 1421 flat and not affect subsequent battery cells. Specifically, the tensile strength of weld 1421 is greater than 110 MPa; the compressive strength of weld 1421 is greater than 1.2 MPa; after more than 2000 fatigue tests at 0.2 MPa pressure, the helium oxide test of weld 1421 still meets the requirements; the compressive strength of weld 1421 under vibration is greater than 1.2 MPa; the compressive strength of weld 1421 under impact is greater than 1.2 MPa. In addition to laser butt welding as described above, high-frequency welding can also be used, which utilizes the skin effect and proximity effect of high-frequency current to rapidly heat the surface metal of the area to be welded, thereby achieving welding.

In conjunction with the above embodiments, the cover plate 2 includes a positive electrode cover plate 21 and a negative electrode cover plate 22. The positive electrode cover plate 21 is disposed at one end of the housing body 1, and the negative electrode cover plate 22 is disposed at the other end of the housing body 1. The first channel 131 is connected to one end of the chip fixing hole 14 and extends towards either the positive electrode cover plate 21 or the negative electrode cover plate 22. The second channel 132 is connected to the other end of the chip fixing hole 14 and extends towards the other of the positive electrode cover plate 21 or the negative electrode cover plate 22, which facilitates a more compact internal structure of the battery housing 100. Furthermore, the chip connector 400c (i.e., positive electrode 401) installed in the first channel 131 and the chip connector 400c (i.e., negative electrode 402) installed in the second channel 132 are far apart and are not prone to mutual interference.

The positive terminal 200 is disposed in the positive terminal hole 211, and the negative terminal 300 is disposed in the negative terminal hole 221. The chip assembly 400 includes at least one chip 403. The chip 403 is embedded in a chip fixing hole 14 and includes a circuit structure 4031 and a detection structure 4032.
