[0015] In a third aspect, the present invention further provides a battery pack, including a lower tray, an upper cover, and the above battery module.
[0016] Those skilled in the art can understand that the technical solution of the present utility model provides a CCS structure, which is applied to a battery module. The battery module includes a plurality of battery cells. The CCS structure is arranged on the top of the battery module. The CCS structure includes a bus bar, an information acquisition component, and a support member. The information acquisition component is arranged between the bus bar and the support member. The information acquisition component includes a main signal acquisition line and a plurality of branch signal acquisition lines. One end of each of the plurality of branch signal acquisition lines is connected to one of the plurality of battery cells in a one-to-one correspondence, and the other end of each of the plurality of branch signal acquisition lines is connected to the main signal acquisition line.

[0031] The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model. For example, although the following embodiments are introduced in combination with a battery pack, the CCS structure provided by the present utility model is equally applicable to other products that need to solve the problem that the information collection of the CCS for the battery is deviated, so that the battery management system cannot accurately control the battery module, affecting the safety of the battery pack.
[0032] It should be noted that in the description of the present utility model, unless otherwise clearly defined and limited, the terms "set" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
[0033] Based on the problem pointed out in the background technology that the existing CCS has a deviation in information collection for the battery, so that the battery management system cannot accurately control the battery module, affecting the safety of the battery pack. The present utility model provides a CCS structure, a battery module and a battery pack, aiming to effectively solve the problem that the CCS has a deviation in information collection for the battery, so that the battery management system cannot accurately control the battery module, affecting the safety of the battery pack by simplifying the transmission path of the CCS for battery information collection.
[0034] First, refer to Figure 1 and Figure 2 , wherein, Figure 1 is a top view of the battery module of the present utility model, Figure 2 is a schematic structural diagram of the information collection component of the present utility model.
[0035] As shown in Figure 1 and Figure 2 , the present utility model provides a CCS structure, which is applied to the battery module 100. The battery module 100 includes a plurality of battery cells 101. The CCS structure is arranged on the top of the battery module 100. The CCS structure includes a bus bar 1, an information collection component 2 and a support member 3. The information collection component 2 is arranged between the bus bar 1 and the support member 3. The information collection component 2 includes a main signal collection line 21 and a plurality of branch signal collection lines 22. One ends of the plurality of branch signal collection lines 22 are respectively connected to the plurality of battery cells 101 in one-to-one correspondence, and the other ends of the plurality of branch signal collection lines 22 are connected to the main signal collection line 21.
[0036] The busbar 1 is located at the top of the battery module 100 and is responsible for the collection and distribution of current. One end of multiple branch signal acquisition lines 22 is connected to multiple battery cells 101 in a one-to-one correspondence, and the other end is connected to the main signal acquisition line 21. By directly connecting the battery cell 101 to the branch signal acquisition line 22, each battery cell 101 can achieve independent information acquisition through a branch signal acquisition line 22, simplifying the transmission path of battery information. The main signal acquisition line 21 is responsible for summarizing the information of each battery cell 101 collected by multiple branch signal acquisition lines 22 and transmitting the information to the battery management system, thereby reducing interference and loss during the information transmission process and improving the accuracy of information acquisition. Accurate information acquisition enables the battery management system to more precisely monitor the state of the battery module 100, promptly discover and handle potential safety hazards, and enhance the safety of the battery pack. The support member 3 can provide structural support for the information acquisition component 2, ensuring the stable position of the information acquisition component 2 within the battery module 100, avoiding displacement or damage caused by vibration or impact, and ensuring the stability and durability of the CCS structure.
[0037] Exemplarily, the material of the support member 3 in the present utility model is an insulating material, such as insulating paint, plastic, synthetic rubber, etc. The present utility model does not make specific limitations on the material of the support member 3; in addition, the manufacturing process of the support member 3 can be made by injection molding, stamping, welding, etc. to ensure the quality and performance of the support member 3. The present utility model does not make specific limitations on the manufacturing process of the support member 3.
[0038] Preferably, as Figures 3 to 5 shown, the branch signal acquisition line 22 includes a circuit board 221, a fixing plate 222, a heat-conducting pad 223, and an adhesive member 224. One side of the heat-conducting pad 223 is connected to the outer shell of the battery cell 101, the fixing plate 222 is arranged on the other side of the heat-conducting pad 223, one end of the circuit board 221 is arranged on the fixing plate 222, the other end of the circuit board 221 is connected to the main signal acquisition line 21, and the fixing plate 222 is fixed to the bottom of the support member 3 through the adhesive member 224.
[0039] The circuit board 221 is the core part of signal acquisition, responsible for transmitting and processing signals from the battery cell 101. One end of the circuit board 221 is fixed on the fixing plate 222 to ensure stable connection and signal transmission. The fixing plate 222 is used to support and fix the circuit board 221 to ensure the stability of the circuit board 221 in the working environment. The fixing plate 222 is arranged on the other side of the heat-conducting pad 223 and is connected to the bottom of the support member 3 through the adhesive member 224 to achieve the stability of the overall structure. The main function of the heat-conducting pad 223 is to collect and transmit the information of the battery cell 101. One side of the heat-conducting pad 223 is connected to the outer shell of the battery cell 101, so as to conduct the heat of the battery cell 101 out in a timely and effective manner, further reducing the loss of the temperature of the battery cell 101, and thus improving the accuracy of temperature control of the battery cell 101. The adhesive member 224 is used to fix the fixing plate 222 (and the circuit board 221 thereon) to the bottom of the support member 3, so as to ensure that the fixing plate 222 will not loosen or fall off during long-term operation. The information of the battery is sequentially transmitted to the battery management system through the heat-conducting pad 223, the fixing plate 222, the circuit board 221 and the main signal acquisition line 21. Compared with the traditional CCS, this transmission path is relatively short, which can effectively reduce the loss of battery information during transmission, and thus improve the accuracy of battery control.
[0040] Preferably, as Figure 2 shown, the fixing plate 222 abuts against the support member 3, and the heat-conducting pad 223 abuts against the outer shell of the battery cell 101, so that the branch signal acquisition line 22 is clamped between the support member 3 and the battery cell 101.
[0041] Since the fixing plate 222 abuts against the support member 3 and the heat-conducting pad 223 abuts against the outer shell of the battery cell 101, the heat-conducting pad 223 can be deformed under force and in a compressed state. Therefore, the thermal resistance in the heat-conducting pad 223 will be relatively small, ensuring that the heat generated by the battery cell 101 can be effectively conducted to the heat-conducting pad 223 and further dissipated through the heat-conducting pad 223, further compressing the transmission path of the information of the battery cell 101, and thus reducing the loss of the branch signal acquisition line 22 for collecting the information of the battery cell 101.
[0042] Exemplarily, the heat-conducting pad 223 in the present invention is heat-conducting silica gel. The heat-conducting silica gel has good heat-conducting performance and flexibility, so that it can have good compressibility. When the heat-conducting silica gel is squeezed by the outer shell of the battery cell 101 and the support member 3, the thermal resistance in the heat-conducting silica gel is reduced, and the heat-conducting effect of the heat-conducting silica gel is improved, thus playing a role in reducing the loss of the information of the battery cell 101 and ensuring the accuracy of collecting the information of the battery cell 101. Of course, in other embodiments, the heat-conducting pad 223 can also be silicone grease, silicone rubber, heat-conducting filler, etc. These materials also have good heat-conducting performance and compressibility, and can improve the heat dissipation efficiency of the battery cell 101. The present invention does not specifically limit the type of the heat-conducting pad 223.
[0043] Exemplarily, the adhesive member 224 in the present utility model is an adhesive tape, and the fixing plate 222 can be preferably fixed to the bottom of the support member 3 through the adhesive tape. Of course, in other embodiments, the adhesive member 224 can also be other materials with adhesiveness, and the adhesive member 224 only needs to be able to provide sufficient adhesive force, and the present utility model does not specifically limit the type of the adhesive member 224.
[0044] Preferably, as Figures 3 to 5 shown, the circuit board 221 includes a first circuit board 2211 and a second circuit board 2212. The first circuit board 2211 is fixedly arranged on the fixing plate 222, the second circuit board 2212 is fixedly arranged on the main signal acquisition line 21, a buffer area 2213 is arranged between the first circuit board 2211 and the second circuit board 2212, and both the first circuit board 2211 and the second circuit board 2212 are connected to the buffer area 2213.
[0045] The first circuit board 2211 is the part fixedly arranged on the fixing plate 222, which is responsible for collecting signals from the battery cell 101. The second circuit board 2212 is the part fixedly arranged on the main signal acquisition line 21, which is responsible for further transmitting the signals from the first circuit board 2211 to the main signal acquisition line 21. The buffer area 2213 is arranged between the first circuit board 2211 and the second circuit board 2212, and its main function is to provide a signal buffer area 2213 to cope with possible fluctuations or interferences during the signal transmission process. For example, during the shaking of the battery module 100, the buffer area 2213 can avoid the circuit board 221 from being pulled in the vertical and horizontal directions, thereby being beneficial to protecting the internal circuits of the circuit board 221 from being damaged, realizing the stable acquisition and effective transmission of the signals of the battery cell 101, and ensuring the accuracy and reliability of the signals of the battery cell 101.
[0046] Preferably, the shape of the adhesive member 224 matches the shape of the fixing plate 222, and the adhesive member 224 is provided with a notch 2241, and the circuit board 221 passes through the notch 2241.
[0047] The shape of the adhesive part 224 matches that of the fixing plate 222, ensuring that the adhesive part 224 can closely adhere to the fixing plate 222, making it not easy to shift or fall off, and improving the structural stability. By providing a notch 2241 in the adhesive part 224, a clearance position is reserved for the circuit board 221, enabling the circuit board 221 to easily pass through the notch 2241 and be fixed on the fixing plate 222, ensuring that the circuit board 221 is not deformed by extrusion, thereby further improving the stability and reliability of the signal acquisition of the battery cell 101. In addition, the close adhesion between the adhesive part 224 and the fixing plate 222, together with the fixing of the circuit board 221 after passing through the notch 2241, constitutes a stable structure, which can effectively resist vibration and impact, ensuring that the circuit board 221 maintains stable performance during long-term use.
[0048] Preferably, the fixing plate 222 is provided with a through groove adapted to the first circuit board 2211, and the first circuit board 2211 is disposed in the through groove and the first circuit board 2211 is in contact with the heat conducting pad 223.
[0049] By bringing the first circuit board 2211 into contact with the heat conducting pad 223, the transmission path of the battery information is further compressed. The battery information is sequentially transmitted to the battery management system through the heat conducting pad 223, the circuit board 221, and the main signal acquisition line 21. The information transmission path is shorter, and the loss of the battery information during transmission is less, thereby further improving the accuracy of battery management.
[0050] Preferably, a fuse is provided on the buffer area 2213.
[0051] When the current exceeds the rated current of the fuse, the fuse will blow, thereby cutting off the circuit and protecting other electronic components in the circuit from damage caused by overcurrent.
[0052] Preferably, as Figure 1 shown, explosion-proof valves 102 are provided on multiple battery cells 101, and avoidance holes corresponding to the multiple explosion-proof valves 102 are provided on both the support member 3 and the main signal acquisition line 21.
[0053] The explosion-proof valve 102 is an important safety component in the battery module 100. Its main function is to automatically open when the internal pressure of the battery rises abnormally (such as due to overcharging, short circuit, high temperature, etc.), release the internal pressure, and prevent the battery from exploding. The avoidance holes provided on the support member 3 and the main signal acquisition line 21 correspond to the positions of the explosion-proof valves 102 on the multiple battery cells 101, thereby ensuring that there are no obstacles blocking its normal operation when the explosion-proof valve 102 opens, and avoiding the risk of electrical failure.
[0054] In a second aspect, the present invention further provides a battery module 100, including a steel strip and the above-mentioned CCS structure.
[0055] The steel strip is mainly used for fixing and protecting the battery cells 101 in the battery module 100. It can firmly fix the battery cells 101 inside the module, preventing the battery cells 101 from moving or being damaged under vibration and impact. At the same time, the steel strip can also provide additional structural support, enhancing the overall stiffness and stability of the module, enabling the module to maintain its shape unchanged when bearing external pressure or load, and extending its service life. In addition, the battery module 100 has the above-mentioned CCS structure, thereby being able to reduce the deviation of battery information collection, so that the battery management system can precisely control the battery module 100 and improve the safety of the battery module 100.
[0056] In a third aspect, the present utility model also provides a battery pack, including a lower tray, an upper cover, and the above-mentioned battery module 100.
[0057] The lower tray is used for supporting and fixing the battery module 100, and can provide a certain degree of protection to prevent the battery module 100 from being damaged by bottom impact, corrosion, etc.; the upper cover is the top structure of the battery pack, mainly playing the role of sealing and protecting the battery module 100. It is tightly connected to the lower tray through a sealing material to form a closed space for placing and protecting the battery module 100. In addition, the battery pack has the battery module 100 with the above-mentioned CCS structure, so it has all the advantages of the CCS structure, can reduce the deviation of battery information collection, so that the battery management system can precisely control the battery module 100 and improve the safety of the battery pack.
[0058] So far, the technical solutions of the present utility model have been described in conjunction with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present utility model is obviously not limited to these specific embodiments. Without departing from the principle of the present utility model, those skilled in the art can make equivalent changes or replacements to the relevant technical features, and the technical solutions after these changes or replacements will all fall within the protection scope of the present utility model.
