Description

Technical Field

[0001] This utility model relates to the field of storage battery technology, and more specifically to an improved storage battery. Background Technology

[0002] Currently, adjacent cells in a battery are connected by busbars, and each busbar is sealed in the battery cover with glue to ensure efficient current transmission inside the battery and reduce the battery's weight. However, when testing traditional batteries, the cover needs to be opened to test internal parameters, which poses a risk of acid exposure.

[0003] Based on this, the Chinese utility model patent CN111672775B, "A Screening Structure and Method for Faulty Cells of Power Batteries," discloses that blind holes are drilled directly above the center of each busbar using a hand drill. A self-tapping screw is screwed into each blind hole, with the bottom of each screw piercing the top surface of the busbar and extending downwards by 1mm-2mm. Simultaneously, bolts are screwed into the top of the positive and negative terminals of the battery. Then, the sampling clamps of a discharge instrument are used to sequentially insert the self-tapping screws. The bolts on the positive and negative terminals of the battery are connected to the discharge instrument for discharge, thereby detecting the voltage of each cell and thus detecting whether the battery is faulty. However, when using the above structure for testing, since there is no limit to the depth of the self-tapping screws into the busbars, once the self-tapping screw pierces the busbar, it will damage the battery. This makes manual operation highly demanding, risky, time-consuming, and labor-intensive. Furthermore, the testing process requires drilling holes in the top cover, making the operation cumbersome. Also, because drilling holes in the top cover is required, this testing method is only suitable for detecting defective products and cannot achieve widespread real-time detection.

[0004] In view of this, this application has conducted in-depth research on this basis, resulting in this case. Utility Model Content

[0005] The purpose of this invention is to provide an improved battery that can not only perform internal single-cell testing and control on the battery body before it leaves the factory, but also is simple, convenient, time-saving and labor-saving, while avoiding the risk of puncturing the busbar during use, and can be widely mass-produced.

[0006] To achieve the above objectives, the solution of this utility model is:

[0007] An improved storage battery includes a battery body, which includes a casing, a top cover covering the casing, a plurality of individual cells arranged sequentially and spaced apart within the casing, and a plurality of busbars. Each pair of adjacent individual cells is connected by a busbar, and each busbar is installed inside the top cover. The top cover and the casing are sealed with glue. A plurality of limiting posts are integrally connected to the upper end face of the top cover. Each limiting post has a through hole, and the projection of each limiting post is located on the busbar. Each limiting post is equipped with an auxiliary component for inserting into the through hole and sequentially piercing the upper end face of the top cover and the busbar.

[0008] A circuit board is mounted on the upper surface of the cover, and each of the limiting posts is distributed within the range of the circuit board.

[0009] A first temperature sensor for detecting temperature is installed on the circuit board near each of the limiting posts.

[0010] Two second temperature sensors are also installed on the circuit board. The positive and negative terminals of the battery body extend out of the top cover through the terminals. Auxiliary guides are installed on the two terminals, and one end of each auxiliary guide is close to the corresponding second temperature sensor.

[0011] The circuit board integrates a control chip, and the acquisition terminals of each of the first temperature sensors and the two second temperature sensors are respectively connected to the signal input terminal of the control chip. The control chip is communicatively connected to the detection platform. Alternatively, the circuit board integrates a control chip and a display screen, and the acquisition terminals of each of the first temperature sensors and the two second temperature sensors are respectively connected to the signal input terminal of the control chip. The control chip and the display screen are bidirectionally electrically connected.

[0012] The opposite side of the top cover is provided with a top cover groove corresponding to the position of each of the busbars. Each top cover groove and each of the busbars are matched one-to-one. The thickness between the bottom surface of each top cover groove and the upper end surface of the top cover is the smallest.

[0013] Each of the busbars is designated as a detection point corresponding to the position between two adjacent cells. Each limiting post and each busbar are respectively paired one-to-one, and each limiting post is projected onto the corresponding detection point. Alternatively, at least three cells arranged sequentially along the length of the top cover are grouped into a cell group, and the busbar located at the middle position between the cells in the cell group is the installation busbar. Each installation busbar is provided with a detection point, and each limiting post is projected onto the corresponding detection point. Alternatively, each busbar has one or two detection points, and each busbar is designated as a detection point corresponding to the position of an adjacent cell. Every two busbars are provided with three detection points on three sequentially adjacent cells, and the projection of each limiting post is located at the corresponding detection point.

[0014] Each of the auxiliary components includes an integrally connected connector and a head. The diameter of each head is larger than the diameter of the through hole in the column. Each connector is installed and fitted with the corresponding through hole in the column.

[0015] The free ends of the connectors of each of the aforementioned auxiliary components are all pointed tips.

[0016] Each of the auxiliary components is a rod-shaped structure made of thermally and / or electrically conductive materials.

[0017] By adopting the above structure, this utility model has the following beneficial effects:

[0018] 1. This utility model employs an integral connection of limiting posts to the top cover. This means that the top cover with limiting posts can be directly formed as a single piece during battery production without altering the battery manufacturing process. Furthermore, in conventional battery assembly, the top cover and all busbars are sealed to the casing with sealant. An auxiliary component is then inserted into the holes of the limiting posts, sequentially piercing the top cover and sealant into the busbars until it is stopped by the limiting posts, preventing further penetration and thus avoiding damage to the battery. This allows for easy and convenient testing of the battery itself, saving time and effort. Since the top cover already has built-in testing points (at the limiting posts), this utility model is widely applicable to both factory testing and routine testing of battery bodies.

[0019] 2. This utility model uses a manifold installed in the groove of the upper cover, and sets the thickness between the bottom of the groove and the upper end of the upper cover to be the thinnest, so as to facilitate the piercing of the auxiliary parts and further improve the convenience of operation.

[0020] 3. This utility model uses a circuit board and temperature sensors. Each temperature sensor is installed on the circuit board according to the location of the detection point. The heat of the busbar is transferred to the auxiliary component through heat transfer. Then, the heat transferred by the auxiliary component is detected by the nearby temperature sensor, so as to obtain the temperature of the corresponding busbar, that is, the temperature parameters between the corresponding single cell or multiple single cells in the battery body, thereby understanding the corresponding condition of the battery body. At the same time, this utility model is widely applicable to mass-produced products with circuit boards installed in the battery body. Attached Figure Description

[0037] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0038] An improved storage battery is provided, which is an improvement on the conventional storage battery. In this embodiment, the storage battery can be a power battery such as a lead-acid battery.

[0039] like Figure 1-6 As shown, the improved battery includes a battery body 100, which includes a casing 1, a top cover 2, several individual cells 3, and several busbars 4. The interior of the casing 1 is divided into several individual cells 3 by partitions. Each individual cell 3 has a group of electrodes inside. Adjacent groups of electrodes are connected by busbars 4. Each busbar 4 is located inside the top cover 2 and is sealed inside the top cover 2 by sealant 9. The top cover 2 and the casing 1 are sealed by potting sealant. This potting sealant is a conventional sealant in the battery manufacturing process and will not be described in detail.

[0040] For ease of description, the reference direction of this utility model is the state of the battery in normal use, with the side of the upper cover 2 facing away from the shell 1 as the upper end surface, and the other side of the upper cover 2 as the opposite side.

[0041] The improvement of this utility model is that, as Figure 3-6 As shown, the upper surface of the aforementioned cover 2 is integrally connected with several limiting posts 5, each limiting post 5 having a through hole 51. In other words, each limiting post 5 and the cover 2 are integrally formed, meaning the cover 2 is manufactured with a limiting post 5 having a through hole 51. This type of cover 2 with limiting posts 5 can be obtained by molding. Each through hole 51 is a hollow structure with an opening at the top, and the lower opening of each through hole 51 is respectively connected to the upper surface of the cover 2. The upper end face is supported, and the projection of each limiting post 5 is located on the corresponding busbar 4. Each limiting post 5 is equipped with an auxiliary part 61, which is used to insert into the through hole 51 of the post body and pierce the upper end face of the upper cover 2 and the busbar 4 in sequence, and extend into the busbar 4. In this way, the auxiliary part 61 is directly connected to the busbar 4 so that the temperature and / or voltage value of the busbar 4 can be detected, thereby detecting the parameters between an independent cell or at least two adjacent cells.

[0042] As a preferred embodiment, springs 52 are inserted into the through holes 51 of each of the aforementioned limiting posts 5, so as to protect the through holes 51 and the auxiliary parts 61 when each auxiliary part 61 is inserted into the through holes 51, and at the same time facilitate the operation of the auxiliary parts 61.

[0043] To elaborate further, such as Figure 1-4As shown, the projections of each limiting post 5 on the battery body 100 fall onto the busbar 4. The positions where each limiting post 5 is projected onto the busbar 4 are used as detection points. In this embodiment, each detection point can be arranged according to actual detection needs. The following describes the commonly used detection point positions during detection, but this embodiment is not limited to the following positions.

[0044] 1. Each busbar 4 has one or two detection points. Specifically, each busbar 4 has a detection point corresponding to the position of a cell 3, and each detection point is adjacent to its corresponding cell 3. For example, there are three detection points on the three cells 3 corresponding to two busbars 4. Depending on the actual situation, two detection points can be set on one busbar 4 and one detection point on the other. The projection of each limiting post 5 is located at its corresponding detection point so that the auxiliary component 61 can fall into the detection point during puncture. This allows for the detection of parameters such as temperature or voltage of the adjacent cells 3 of the busbar 4, i.e., the detection of parameters of each cell 3 for monitoring.

[0045] 2. Each busbar 4 is provided with a detection point, which is located on each busbar 4 at the position corresponding to two adjacent cells 3. Preferably, the detection point is located at the middle position between two adjacent cells 3. The vertical projection of each limiting post 5 is located at the corresponding detection point, that is, each limiting post 5 corresponds to a detection point. In this way, parameters such as temperature or voltage of each busbar 4 can be detected, that is, the parameters between two adjacent cells 3 can be detected, so as to monitor the two adjacent cells 3. For example, if the voltage is monitored, if the detected voltage is within the set range, it can be determined that the voltage parameters of the two adjacent cells 3 are normal.

[0046] For example, let's take a battery body 100 with six cells 3 as an example. The six cells have five busbars 4. Each busbar 4 is arranged in the manner of the top cover of a conventional battery. Each busbar 4 has a detection point at the middle position between two cells 3. This detection point corresponds to the through hole 51 of the limit post 5.

[0047] 3. The detection points on each busbar 4 are not the same. Each busbar may have one or no detection point. Specifically, each cell 3 is set up in a group of at least three. In this embodiment, three cells 3 are set up as a group. The cells arranged in threes along the length of the upper cover 2 are set up as a group. The busbar that is close to the middle position between all cells in the cell group is the installation busbar. Each installation busbar is provided with a detection point. The non-installation busbars in each busbar are not provided with detection points. Preferably, the detection point on each installation busbar can be located at the middle position between each cell. The projection of each limiting post 5 is located at the detection point. In this way, the temperature or voltage of each installation busbar can be detected, that is, the parameters of each cell group can be detected, so as to monitor each cell group. For example, if the voltage is monitored, if the detected voltage is within the set range, it can be determined that the voltage parameter of the cell group is normal. If the detected voltage exceeds the set range, it can be determined that the cell in the cell group is faulty.

[0048] As a preferred embodiment, the opposite side of the upper cover 2 is provided with upper cover grooves 21 corresponding to the positions of each busbar 4. Each upper cover groove 21 and each busbar 4 are matched one-to-one, that is, each busbar 4 is fixedly installed in the corresponding upper cover groove 21. The bottom of each upper cover groove 21 has the same thickness as the upper end face of the upper cover 2. This thickness is the minimum thickness of the upper cover 2. That is, the bottom of the upper cover groove 21 is the thinnest position of the upper cover 2, so as to facilitate the subsequent auxiliary component 61 to pierce the upper cover 2 and extend into the busbar 4.

[0049] Furthermore, in the aforementioned battery body 100, each auxiliary component 61 includes an integrally connected connector and a head. The diameter of each head is larger than the diameter of the through hole 51 of the limiting post 5. Each connector is installed and fitted with the corresponding through hole 51. Preferably, the free end of each auxiliary component 61 is a pointed tip to facilitate piercing the top cover 2 and the busbar 4. Thus, when the auxiliary component 61 is inserted into the corresponding through hole 51, its connector penetrates into the through hole 51 and successively pierces the thickness of the top cover 2 and the upper end face of the busbar 4, extending into the busbar 4 by 1-2.5mm. At this time, the head abuts against the upper end face of the limiting post 5 to restrict the auxiliary component 61 from moving further downward, thereby preventing the auxiliary component 61 from piercing the busbar and damaging the battery.

[0050] In this embodiment, each auxiliary component 61 is a rod-shaped structure made of a thermally and electrically conductive material. Each auxiliary component 61 can be a conventional assembly part such as a screw, self-tapping screw, or nail. Preferably, in this embodiment, the auxiliary component 61 is a self-tapping screw.

[0051] like Figure 1-2 As shown and as Figure 5-6As shown, a circuit board 7 can be installed on the upper surface of the cover 2. The circuit board 7 has through holes 71 corresponding to the positions of each limiting post 5. Preferably, the upper surface of the cover 2 has a mounting groove 22, the shape and size of which are adapted to the shape and size of the circuit board 7. The circuit board 7 is embedded in the mounting groove 22, and each limiting post 5 is distributed at the bottom of the mounting groove 22, meaning the distribution range of the circuit board 7 corresponds to all busbars 4. The circuit board 7 can be installed in the mounting groove 22 using conventional installation methods such as welding, embedding, or bolting. It should be noted that the cover 2 has individual interface points corresponding to each individual compartment 3. When the circuit board 7 is installed, each individual interface point is exposed. The installation of the individual interface points is a standard procedure for the cover 2 and will not be described further.

[0052] Furthermore, the circuit board 7 is equipped with a plurality of first temperature sensors 81, each first temperature sensor 81 being paired with each limiting post 5 in a one-to-one manner. Each first temperature sensor 81 is adjacent to the corresponding limiting post 5 to detect the temperature of the auxiliary component 61 on the adjacent limiting post 5. In this embodiment, each first temperature sensor 81 can be located on the upper side of the circuit board 7 or on the lower side of the circuit board 7. The specific position is set according to the actual situation and is not limited here.

[0053] Furthermore, two second temperature sensors 82 are also installed on the circuit board 7. The positive and negative terminals of the battery body 100 extend out of the top cover 2 through the terminals 11. The structure and installation structure of the positive terminal, negative terminal, and terminals 11 of the battery body 100 are the same as those of a conventional battery, so they will not be described in detail. The two second temperature sensors 82 are paired with the two terminals 11 one-to-one. The two second temperature sensors 82 are close to the corresponding terminals 11. The two terminals 11 are each equipped with an auxiliary guide 62. The two auxiliary guides 62 are respectively screwed onto the outside of the corresponding terminals 11, and one end of the two auxiliary guides 62 is close to the corresponding second sensor 82. In this way, the temperature at the positive terminal and the negative terminal is detected through the heat transfer of the auxiliary guides 62.

[0054] Furthermore, both auxiliary guides 62 include an annular portion, a connecting portion, and a transmission portion that are integrally connected in sequence. Both auxiliary guides 62 are L-shaped and have the same installation structure. Therefore, one of them will be used as an example for explanation. The annular portion of the auxiliary guide 62 is sleeved on the bolt, that is, the annular portion is stacked on the end face of the corresponding pole post 11 so that the auxiliary guide 62 can be clamped between the head of the bolt and the end face of the pole post 11 during installation. The connecting portion extends across the top of the circuit board 7 and corresponds to the second temperature sensor 82. The transmission portion is close to or abuts against the second temperature sensor 82. In this embodiment, both auxiliary guides 62 are made of thermally and electrically conductive materials. Both auxiliary guides 62 can be made of metal materials such as stainless steel and copper. During testing, the positive and negative terminals transfer heat through their respective terminals 11. Since the two auxiliary conductors 62 are in contact with their respective terminals 11, the terminals 11 transfer heat to their respective auxiliary conductors 62. Then, the two second temperature sensors 82 detect the temperature on their respective auxiliary conductors 62, thereby obtaining the temperature data at the negative and positive terminals on the battery body 100.

[0055] In this embodiment, both terminals 11 are conventional terminals suitable for use in batteries, and both terminals 11 are threaded terminals; and each first temperature sensor 81 and the two second temperature sensors 82 are conventional temperature sensors, such as NTC thermistors or surface mount temperature sensors.

[0056] Furthermore, the aforementioned circuit board 7 integrates a control chip. Each of the first temperature sensors 81 and the two second temperature sensors 82 are electrically connected to the sampling end of the control chip. The control chip can communicate with the testing platform via wire connection or wireless connection to transmit the temperature data detected by each temperature sensor to the testing platform, facilitating real-time viewing of temperature data by testing personnel during battery testing. The wireless connection method can be a conventional existing communication method, which will not be described in detail here. In this embodiment, the circuit board integrating the control chip is a conventional existing circuit board. Preferably, the circuit board 7 also integrates a display screen, which is bidirectionally electrically connected to the control chip to display the data detected at the testing points, such as temperature data.

[0057] It should be noted that the aforementioned battery body 100 can also detect voltage parameters, namely, the aforementioned limit posts 5.

[0058] It should be noted that in the produced top cover 2, the column perforation 51 on each limiting post 5 is mutually blocked from the corresponding busbar 4 by the top cover 2; in the battery body 100, the top cover 2 is filled with sealant 9, that is, there is also sealant 9 between the bottom of the groove 21 on the top cover 2 and the busbar 4, so as to achieve the effect of sealing and insulation.

[0059] This utility model discloses an improved storage battery. Before factory testing, post-sale testing, or after installation on a circuit board in a mass-produced product, an auxiliary component (such as a self-tapping screw) is screwed into the through hole 51 of the column and pierces through the cover 2 into the groove 21 of the upper cover. Then, it is screwed into the sealant 9 until the tip of the self-tapping screw is at the detection point of the busbar 4. It is then screwed in until the head of the self-tapping screw is restricted to the upper end face of the limiting post 5. At this point, the tip of the self-tapping screw penetrates 1.5mm into the busbar 4. Then, temperature data of the corresponding detection points and the positive and negative terminals can be obtained by each temperature sensor. Then, the acquisition clamp of a conventional discharge instrument is clamped onto the self-tapping screw, and the bolts on the positive and negative terminals are connected to the discharge instrument for discharge. The discharge voltage and discharge time of the discharge instrument are adjusted to obtain the voltage data of each detection point. This is used to detect the voltage and temperature data of each cell or at least two cells in the storage battery body 100 to determine whether the storage battery body 100 is abnormal. It should be noted that the voltage detection method described above can also be performed using other existing conventional methods, and is not limited to the methods described above.

[0060] Compared with the prior art, this improved battery has several advantages. Because the produced top cover 2 itself has several limiting posts 5, no drilling is required in the assembled battery body 100. Furthermore, the top cover 2 is simpler and easier to process, allowing for mass production. Additionally, since the top cover 2 and the housing 1 are sealed with sealant 9 before testing, and the bottom of each limiting post 2 is the upper surface of the top cover 2, it avoids sealant seepage during the sealing process, which could affect the insulation and sealing performance of the top cover 2. Moreover, the combination of each limiting post... The vertical projection of 5 can fall on the detection points of busbar 4 respectively. Therefore, when the battery body 100 needs to be tested, the tester can screw the auxiliary part 6 from the limiting post 5 into the top cover 2 and insert it into the detection point of busbar 4 to test the corresponding single cell or multiple single cells. The operation is simple and convenient, and there is no need to consider the position of the drill hole corresponding to the detection point, nor is there any need to worry about not hitting the busbar during drilling. In addition, due to the limitation of the limiting post 5, the auxiliary part 6 can be adapted to more and wider sizes, and can be screwed in directly without worrying about piercing the busbar.

[0061] The above description is only a preferred embodiment of this invention. All equivalent changes and modifications made within the scope of the claims of this utility model shall fall within the scope of the claims of this utility model.
