Description

A battery testing device Technical Field

[0001] The present application relates to the field of battery technology, and in particular to a battery testing device. Background Art

[0002] Currently, battery insulation and pressure resistance are primarily tested using battery testing devices. These devices consist of a lifting mechanism and a probe mechanism, which is fixedly connected to the lifting mechanism. The probe mechanism includes multiple probes, the spacing between which matches the spacing between the electrode terminals of each battery cell in the battery. This spacing is determined by the size of the battery cells. The lifting mechanism pushes the probe mechanism close to the battery, allowing the probes to contact the electrode terminals of the battery cells for testing.

[0003] To ensure accurate and reliable contact between the probes and the electrode terminals, multiple probes are typically fixed on a lifting mechanism, maintaining a fixed spacing between the probes. As the size of the battery cell changes, the spacing between the probes needs to be adjusted to match the spacing between the electrode terminals.

[0004] When adjusting the spacing between the probes, since there are a large number of probes and each probe is fixedly mounted on a lifting mechanism, it may take a long time to adjust the spacing between the probes, resulting in the battery testing device being unable to quickly adapt to batteries composed of battery cells of different sizes, thereby reducing the testing efficiency of the battery testing device.

DETAILED DESCRIPTION

[0055] The following embodiments of the technical solution of the present application will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present application and are therefore only examples and are not intended to limit the scope of protection of the present application.

[0056] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned figure descriptions are intended to cover non-exclusive inclusions.

[0057] In the description of the embodiments of this application, the technical terms "first" and "second" are used only to distinguish different objects and should not be understood to indicate or imply relative importance or implicitly specify the quantity, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, the meaning of "plurality" is more than two, unless otherwise clearly and specifically defined.

[0058] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0059] In the description of the embodiments of this application, the term "and / or" is simply a description of the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent the following three situations: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0060] A battery's insulation and pressure resistance determine its safe and reliable operation. Therefore, they must be tested during the manufacturing process. A battery, also known as a pack, can consist of multiple battery cells connected in series and / or parallel, or multiple battery modules connected in series and / or parallel. Each battery module consists of multiple battery cells (also called cells) connected in series and / or parallel.

[0061] Currently, the insulation and voltage resistance of batteries are mainly tested using a battery testing device. The battery testing device includes, but is not limited to, a lifting mechanism and a probe mechanism, as well as a controller, a circuit, a voltage tester, and a multimeter.

[0062] During the test, the lifting mechanism can drive the probe mechanism up and down, pushing the probe mechanism to a position close to the battery, so that the probes in the probe mechanism contact the electrode terminals of the battery cells in the battery. After the test is completed, the lifting mechanism can drive the probe mechanism up and down again to separate the probes from the electrode terminals.

[0063] Among them, the probe in the probe mechanism is electrically connected to the relay in the circuit. After the probe is in contact and connected with the electrode terminal, the controller can control the various relays in the circuit to be in an on or off state, so as to connect the various battery cells in the battery in series and / or in parallel, and connect the battery cells after series and / or parallel connection to a voltage tester or a multimeter, and perform a voltage test or insulation test on the battery through the voltage tester or the multimeter.

[0064] The spacing between two adjacent probes in the probe mechanism corresponds to the spacing between the electrode terminals of two adjacent battery cells in the battery. During testing, to ensure accurate and reliable contact between the probes and the electrode terminals, and thus guarantee the accuracy of the test results, each probe is fixedly mounted on the probe mechanism. This ensures a constant spacing between the probes, allowing the battery testing device to accurately test batteries composed of battery cells of a certain size.

[0065] When the size of the battery cell changes, the distance between the electrode terminals of two adjacent battery cells will change. It is necessary to adjust the distance between the probes to match the distance between the electrode terminals in the battery so that the probes can accurately contact the electrode terminals.

[0066] The probe mechanism is usually located inside the battery testing device, which is not convenient for staff to operate directly, making it difficult to adjust the spacing between the probes. Moreover, each probe is fixedly connected to the lifting mechanism, and the number of probes is relatively large. Therefore, it takes a long time to adjust the spacing between the probes, resulting in the battery testing device may not be able to quickly adapt to batteries composed of battery cells of different sizes, reducing the testing efficiency of the battery testing device.

[0067] In order to solve the above technical problems, an embodiment of the present application provides a battery testing device, including: a lifting mechanism and a probe mechanism, the lifting mechanism is used to drive the probe mechanism to move; the probe mechanism includes an adapter bracket, and a plurality of first connecting members arranged on the adapter bracket, and the adapter bracket is detachably connected to the lifting mechanism.

[0068] In an embodiment of the present application, the probe mechanism is detachably connected to the lifting mechanism through an adapter bracket. When the size of the battery cell changes and the spacing between the probes needs to be adjusted, the adapter bracket and the lifting mechanism can be separated first, and the probe mechanism can be taken out of the battery testing device to adjust the spacing between the probes outside the battery testing device. This can reduce the difficulty of operation and improve the adjustment efficiency, thereby shortening the time spent on adjusting the spacing between the probes, so that the battery testing device can be quickly adapted to batteries composed of battery cells of different sizes, thereby improving the testing efficiency of the battery testing device.

[0069] Alternatively, a spare probe mechanism can be provided. When the size of the battery cell changes, the adapter bracket can be separated from the lifting mechanism and the entire probe mechanism can be directly replaced, achieving rapid conversion to adapt to different types of battery cells, thereby improving testing efficiency.

[0070] The size of a battery cell generally corresponds to the model number. Different battery cell models often have different sizes. The battery testing device can quickly adapt to batteries composed of battery cells of different sizes. Therefore, the battery testing device can quickly switch between batteries composed of battery cells of different models, allowing the battery testing device to quickly and flexibly adapt to batteries composed of battery cells of different models.

[0071] Figure 1 illustrates a battery testing scenario according to some embodiments of the present application. As shown in Figure 1 , battery testing apparatus 1 includes a host computer 11, a controller 12, a multimeter 13, a voltage tester 14, a circuit 15, a probe mechanism 16, and the like. Host computer 11 can be a computer, laptop, or industrial personal computer, and controller 12 can be, for example, a programmable logic controller (PLC), but is not limited thereto.

[0072] The probes in probe mechanism 16 can contact the electrode terminals of the battery cells included in battery 2 to achieve electrical connection with the electrode terminals. Circuit 15 includes multiple relays connected in series and / or parallel. The multiple probes in probe mechanism 16 are respectively connected to different relays in circuit 15. Furthermore, some relays in circuit 15 are electrically connected to multimeter 13 and voltage tester 14.

[0073] Controller 12 is electrically connected to each relay in circuit 15 and can control the relays to be on or off. During battery 2 testing, after the probes in probe mechanism 16 contact the electrode terminals of a battery cell in battery 2, controller 12 can control the relays in circuit 15 to be on or off, thereby connecting the battery cells in battery 2 in series and / or in parallel. The controller 12 then connects the series and / or parallel connected battery cells to a multimeter 13 or a voltage tester 14, and then activates the voltage tester 14 to perform a voltage test on the battery, or activates the multimeter 13 to perform an insulation test on the battery.

[0074] The above are merely illustrative examples, and the specific composition of the battery testing device may include but is not limited to the above examples.

[0075] FIG2 is a partial structural diagram of a battery testing device provided in some embodiments of the present application. As shown in FIG2 , the battery testing device includes a frame 31 , a lifting mechanism 32 , and a probe mechanism 33 .

[0076] Exemplarily, the rack 31 may be a frame structure assembled from a plurality of beams and a plurality of columns, with a first storage space 34 formed at the top and a second storage space 35 formed at the bottom. A probe mechanism 33 is mounted at the top of the first storage space 34, and a tray 36 for placing batteries is provided at the bottom. The second storage space 35 is used to store spare components, such as a spare probe mechanism 33. A lifting mechanism 32 is mounted at the top of the rack 31, with the movable end of the lifting mechanism 32 extending into the first storage space 34 and connected to the probe mechanism 33.

[0077] The direction Y is a vertical direction, the direction X is a horizontal direction perpendicular to the direction Y, and the direction Z is another horizontal direction perpendicular to the direction X. The top, upper part, and lower part are relative area divisions in the Y direction.

[0078] The lifting mechanism 32 can move the probe mechanism 33 up and down in the Y direction, causing the probes in the probe mechanism 33 to contact or separate from the electrode terminals of the battery cells. When the probe mechanism 33 moves to a position close to the battery placed on the tray 36, the probes in the probe mechanism 33 contact the electrode terminals of the battery, allowing the battery to be tested.

[0079] Figure 3 illustrates a schematic structural diagram of a lifting mechanism provided in some embodiments of the present application. As shown in Figure 3, the lifting mechanism 32 includes a mounting plate 322, which is fixedly connected to the crossbeam at the top of the frame 31, thereby securing the entire lifting mechanism 32 to the top of the frame 31. The lifting mechanism 32 also includes a movable plate 323, which constitutes the movable end of the lifting mechanism 32. The movable plate 323 is located in the first accommodating space 34 and can be connected to the probe mechanism 33 to drive the probe mechanism 33 to rise and fall in the Y direction.

[0080] Exemplarily, the driving element of the lifting mechanism 32 is a servo motor 324, shown in FIG3 . The servo motor 324 is fixedly mounted on the mounting plate 322, with the movable end of the servo motor 324 connected to the movable plate 323. A plurality of linear bearings 325 are also spaced apart on the mounting plate 322. The linear bearings 325 are fixedly connected to each other by a connecting plate 326, and the movable ends of the linear bearings 325 are connected to the movable plate 323. When the servo motor 324 is in operation, the linear bearings 325 drive the movable plate 323 to perform linear motion in the Y direction, thereby driving the probe mechanism 33 to rise and fall in the Y direction.

[0081] The mounting plate 322 is also provided with a plurality of balancing cylinders 327 spaced apart. For example, two balancing cylinders 327 may be provided, symmetrically arranged on either side of the servo motor 324. The movable ends of the balancing cylinders 327 are connected to the movable plate 323, thereby offsetting some or all of the weight of the movable plate 323 and the probe mechanism 33, reducing the load on the servo motor 324, thereby improving the stability of the battery testing device, extending the service life of the servo motor 324, and further enhancing the reliability of the battery testing device.

[0082] It should be understood that the specific structure and composition of the lifting mechanism 32 may include but are not limited to that shown in FIG. 3 .

[0083] In some embodiments of the present application, the probe mechanism 33 includes an adapter bracket 332 and a plurality of first probes 331 disposed on the adapter bracket 332 . The adapter bracket 332 is detachably connected to the lifting mechanism 32 .

[0084] Among them, the probe mechanism 33 is detachably connected to the lifting mechanism 32 through the adapter bracket 332. When the size of the battery cell changes and the spacing between the probes 331 needs to be adjusted, the adapter bracket 332 and the lifting mechanism 32 can be separated first, and the probe mechanism 33 can be taken out from the battery testing device to adjust the spacing between the probes 331 outside the battery testing device. This can reduce the difficulty of operation and improve the adjustment efficiency, thereby shortening the time spent on adjusting the spacing between the probes 331, so that the battery testing device can quickly adapt to batteries composed of battery cells of different sizes, thereby improving the testing efficiency of the battery testing device.

[0085] In some embodiments, one side of the adapter bracket 332 is detachably connected to the lifting mechanism 32 , and the other side is provided with two opposite first connecting parts 333 , and a plurality of first connecting members 339 are installed between the two first connecting parts 333 .

[0086] Figure 4 shows a schematic diagram of the structure of a probe mechanism provided in some embodiments of the present application. As shown in Figure 4, the adapter bracket 332 is a strip-shaped plate. One side of the strip-shaped plate is detachably connected to the lifting mechanism 32. The other side of the strip-shaped plate has a first connecting portion 333 at one end along the X direction and another first connecting portion 333 at the other end. One end of the first connecting portion 333 is connected to the strip-shaped plate, and the other end extends a certain distance away from the probe mechanism 33.

[0087] The two first connection parts 333 can be located at either end of the adapter bracket 332, or near the end of the adapter bracket 332. The first connection part 333 can be a connecting plate as shown in FIG4 , and one end of the first connection part 333 can be fixedly connected to the adapter bracket 332 by rivets or screws, or by welding or gluing. Alternatively, the two first connection parts 333 can be integrally formed with the adapter bracket 332.

[0088] As shown in FIG. 4 , the adapter bracket 332 and the two first connecting parts 333 form an accommodating space for accommodating a plurality of first probes 331 on a side away from the lifting mechanism 32 . The plurality of first probes 331 can be installed between the two first connecting parts 333 .

[0089] It is understood that the adapter bracket 332 and the first connecting portion 333 can be a hollow plate with a hollow area as shown in Figure 4, or a flat plate without a hollow area, and can be a flat plate or a curved plate with a certain curvature. The specific structure of the adapter bracket 332 and the first connecting portion 333 can include but is not limited to the above examples.

[0090] In an embodiment of the present application, two opposing first connecting parts 333 are provided on the adapter bracket 332, and a plurality of first probes 331 can be installed between the two first connecting parts 333. The structure of the entire probe mechanism 33 is relatively simple and has a larger operating space, which can facilitate the staff to adjust or maintain the first probe 331 between the two first connecting parts 333.

[0091] In some embodiments, the probe mechanism 33 includes a first guide rail 334 , both ends of the first guide rail 334 are respectively connected to two first connecting parts 333 , and a plurality of first probes 331 are mounted on the first guide rail 334 .

[0092] Figure 5 shows a partial structural diagram of a probe mechanism provided in some embodiments of the present application. As shown in Figure 5, the probe mechanism 33 includes two parallel first guide rails 334, which are arranged along the X direction, and one end of the first guide rail 334 is connected to a first connecting portion 333, and the other end is connected to another first connecting portion 333.

[0093] Among them, the probe mechanism 33 may include one first guide rail 334 or multiple parallel first guide rails 334, each first guide rail 334 is equipped with multiple first connecting parts 339, the first probe 331 can be installed on the first connecting part 339, and at least one first probe 331 can be installed on each first connecting part 339.

[0094] When the probe mechanism 33 includes one first guide rail 334, a row of first probes 331 on the first guide rail 334 can contact a row of electrode terminals in the battery. When the probe mechanism 33 includes two parallel first guide rails 334, the two rows of first probes 331 on the two first guide rails 334 are used to contact two rows of electrode terminals in the battery, respectively.

[0095] The first guide rail 334 may be made of a strong insulating material to carry the plurality of first connectors 339 and may be insulated and isolated from the first probes 331 on the first connectors 339 , thereby improving the accuracy of the test.

[0096] In the embodiment of the present application, multiple first probes are installed on the first guide rail between the two first connecting parts, which can simplify the structure of the probe mechanism and reduce the weight of the probe mechanism, making it easier for staff to disassemble the probe mechanism.

[0097] In some embodiments, the probe mechanism 33 includes a plurality of first guide rails 334 arranged in parallel, and the distance between two adjacent first guide rails 334 is adjustable.

[0098] As shown in FIG. 4 , the probe mechanism 33 includes two first guide rails 334 . The two first guide rails 334 are arranged in parallel, and the distance between the two first guide rails 334 is adjustable.

[0099] In some embodiments, a second guide rail 335 is provided on the first connecting portion 333 , and the first guide rail 334 is slidably connected to the first connecting portion 333 via the second guide rail 335 .

[0100] As shown in FIG. 4 , the second guide rail 335 can be installed at one end of the first connection portion 333 away from the adapter bracket 332 . The second guide rail 335 is arranged along the Z direction, and the first guide rail 334 is perpendicular or nearly perpendicular to the second guide rail 335 .

[0101] The second guide rail 335 is provided with a second slideway 3316, and the end of the first guide rail 334 is located in the second slideway 3316. At the same time, the end of the first guide rail 334 is provided with a second fixing member 3315, which is used to fix the first guide rail 334 in the second slideway 3316.

[0102] For example, the second fixing member 3315 may be a knob that is rotatably connected to the end of the first guide rail 334 to adjust the distance between the knob and the first guide rail 334. When the knob is loosened, the distance between the knob and the first guide rail 334 is larger, and the first guide rail 334 can slide in the second slide 3316, thereby adjusting the position of the first guide rail 334 on the second guide rail 335.

[0103] On the contrary, when the knob is tightened, the distance between the knob and the first guide rail 334 is smaller, and the first guide rail 334 can be stuck in the second slide 3316, thereby fixing the position of the first guide rail 334 on the second guide rail 335.

[0104] As shown in Figure 5, the spacing between the two first guide rails 334 can be adjusted by adjusting the position of the first guide rail 334 on the second guide rail 335. The two opposing first probes 331 on the two first guide rails 334 are used to contact the two electrode terminals on the same battery cell. When the spacing between the two first guide rails 334 is adjustable, the probe mechanism 33 can be adapted to accommodate battery cells of varying widths.

[0105] The second guide rail 335 may be fixedly mounted on the first connecting portion 333 by rivets or screws. Alternatively, the second guide rail 335 may be integrally formed with the first connecting portion 333. The specific structure of the second guide rail 335 and the connection method between the second guide rail 335, the first connecting portion 333, and the first guide rail 334 may include but are not limited to the above examples.

[0106] In the embodiment of the present application, the probe mechanism includes a second guide rail, and the spacing between the first guide rails can be adjusted through the second guide rail, so that the probe mechanism can be applicable to battery cells of different sizes, thereby making the battery testing device more compatible.

[0107] In some embodiments, the lifting mechanism 32 is provided with a plurality of first connectors 321 spaced apart along the length of the first guide rail 334. The adapter bracket 332 is provided with second connectors 336 corresponding to the first connectors 321, and the second connectors 336 are plugged into the corresponding first connectors 321.

[0108] As shown in Figure 3, the first connector 321 can be a plug-in slot. Two first connectors 321 are set at the bottom of the movable plate. The two first connectors 321 are set at a certain distance along the X direction, so that the two first connectors 321 can be set at intervals along the length direction of the first guide rail 334.

[0109] As shown in Figure 4, two second connectors 336 are provided on one side of the adapter bracket 332 away from the first guide rail 334, spaced apart along the length of the first guide rail 334. The distance between the two first connectors 321 matches the distance between the two second connectors 336, and the shape of the first connector 321 matches the shape of the second connector 336.

[0110] The second connector 336 may be a flat connector as shown in FIG4 , and the first connector 321 may be a U-shaped connector as shown in FIG3 . The size of the second connector 336 is slightly smaller than that of the first connector 321 , so that the second connector 336 can be inserted into the first connector 321 .

[0111] As shown in Figure 2, during the installation process of the probe mechanism 33, the probe mechanism 33 can be lifted to the upper part of the first accommodating space 34, so that the two second connectors 336 are respectively opposite to the two first connectors 321, and then the probe mechanism 33 is pushed along the Z direction so that the two second connectors 336 are respectively inserted into the corresponding first connectors 321, so that the probe mechanism 33 can be installed at the movable end of the lifting mechanism 32.

[0112] On the contrary, when the probe mechanism 33 needs to be removed from the battery testing device, the probe mechanism 33 can be pulled in the opposite direction of the Z direction. When the second connector 336 is separated from the first connector 321, the probe mechanism 33 can be removed from the entire battery testing device.

[0113] As shown in FIG. 4 , when only two first connectors 321 are provided at the bottom of the lifting mechanism 32 , the two first connectors 321 can be respectively provided on both sides of the lifting mechanism 32 to improve the stability of the probe mechanism 33 .

[0114] In actual applications, the bottom of the lifting mechanism 32 can also be equipped with 3, 4 or 5 first connectors 321 at intervals along the length direction of the first guide rail 334, and the adapter bracket 332 can be equipped with a second connector 336 corresponding to each first connector 321.

[0115] It should be noted that the first connector 321 can be a U-shaped slot as shown in FIG. 4 , or a C-shaped slot or a connector of other shapes, as long as the shapes and positions of each pair of second connectors 336 and first connectors 321 match.

[0116] In an embodiment of the present application, the probe mechanism and the lifting mechanism are detachably connected through a second plug-in connector and a first plug-in connector that are plugged into each other, which can facilitate the staff to disassemble and install the probe mechanism, thereby improving the disassembly and installation efficiency of the probe mechanism, and further improving the testing efficiency of the battery testing device.

[0117] In some embodiments, the battery testing device further includes a support mechanism 37 arranged in parallel with the probe mechanism 33 . The support mechanism 37 is used to support the probe mechanism 33 when the probe mechanism 33 is separated from the lifting mechanism 32 .

[0118] Figure 6 shows an enlarged schematic diagram of area A in Figure 2. As shown in Figure 6, the support mechanism 37 includes a plurality of unpowered rollers 371 and a mounting track 372. The unpowered rollers 371 are mounted in the mounting track 372, and the plurality of unpowered rollers can rotate in the mounting track 372.

[0119] As shown in Figure 2, two support mechanisms 37 are provided at each end of the probe mechanism 33. These support mechanisms 37 are located on one side of the probe mechanism 33 in the lifting direction and are arranged side by side with the probe mechanism 33 within the first accommodating space 34. Furthermore, the first connecting portion 333 corresponds to the unpowered roller 371 at the same end and is located above the unpowered roller 371 in the Y direction, at a predetermined distance from the unpowered roller 371. When the probe mechanism 33 is separated from the lifting mechanism 32, the first connecting portion 333 can rest on the corresponding unpowered roller 371.

[0120] A second handle 3317 is provided on the adapter bracket 332. During the process of disassembling the probe mechanism 33, the probe mechanism 33 can be pulled in the opposite direction of the Z direction by the second handle 3317. When the second connector 336 is detached from the first connector 321, the two second guide rails 335 can respectively fall on a corresponding set of support mechanisms 37 and slide on the support mechanisms 37. When the second connector 336 is completely separated from the first connector 321, the probe mechanism 33 can be removed from the two support mechanisms 37, and the probe mechanism 33 can be taken out of the first accommodating space 34 to complete the disassembly of the probe mechanism 33.

[0121] During the installation of the probe mechanism 33, the probe mechanism 33 can first be placed on the support mechanisms 37 at both ends, and then the probe mechanism 33 can be pushed along the Z direction. Under the action of the support mechanism 37, the second connector 336 can be inserted into the corresponding first connector 321 to complete the installation of the probe mechanism 33.

[0122] It should be noted that the specific types of the support mechanism 37 may include but are not limited to the above examples.

[0123] In the embodiment of the present application, a support member is installed in the battery testing device, which can reduce the difficulty of disassembling and installing the probe mechanism, and can realize the rapid installation and disassembly of the probe mechanism, thereby improving the testing efficiency of the battery testing device.

[0124] In some embodiments, the battery testing device also includes a safety mechanism. For example, the safety mechanism can be a safety grating 39 shown in FIG2 . A set of safety gratings 39 can be provided at each end of the probe mechanism 33 . The safety gratings 39 are electrically connected to a controller in the battery testing device. After the battery testing device is started, if a foreign object enters the first receiving space 34 from either end of the probe mechanism 33 , the safety gratings 39 can send an alarm signal to the controller. Upon receiving the alarm signal, the controller can control the battery testing device to stop.

[0125] For example, the safety mechanism may further include a safety switch 310, which is disposed on the frame 31 and electrically connected to the controller. During operation of the battery testing device, the safety switch 310 is in a closed state and can send a closing signal to the controller. Upon receiving the closing signal, the controller controls the normal operation of the battery testing device.

[0126] During maintenance of the battery testing device, a worker can manually disconnect the safety switch 310 , and the safety switch 310 can send a disconnection signal to the controller. After receiving the disconnection signal, the controller controls the battery testing device to shut down and prohibits the battery testing device from starting up.

[0127] The installation of the switch 310 can facilitate the staff to manually stop the battery testing device during maintenance of the battery testing device, reduce the probability of the battery testing device being accidentally started during maintenance, effectively protect the staff, and thus improve the safety and reliability of the battery testing device.

[0128] For example, the safety mechanism may include a safety assembly consisting of a safety beam 38 and a switch element (not shown) located at the bottom of the safety beam 38. The switch element is electrically connected to the controller. During operation of the battery testing device, the safety beam 38 is placed above the switch element, closing the switch element. The switch element sends a closing signal to the controller, which controls the normal operation of the battery testing device.

[0129] During maintenance of the battery tester, a worker may remove the safety beam 38 from the switch element to disconnect the switch element and send a disconnect signal to the controller. Upon receiving the disconnect signal, the controller controls the battery tester to shut down and prohibits the battery tester from starting.

[0130] The safety beam 38 and the switch element can facilitate the staff to manually stop the battery testing device during the maintenance process of the battery testing device, reduce the probability of the battery testing device being accidentally started during the maintenance process, effectively protect the staff, and thus improve the safety and reliability of the battery testing device.

[0131] It should be understood that the specific type of the security mechanism can be set according to needs, and may include but is not limited to the above examples.

[0132] In some embodiments, a first fixing member 3212 is provided on the first connector 321 , and the first fixing member 3212 is used to fix the second connector 336 on the corresponding first connector 321 .

[0133] Figure 7 shows an enlarged schematic diagram of area B in Figure 3. As shown in Figure 7, the first fixing member 3212 is, for example, a cylindrical pin. Pin holes are defined at corresponding positions of the first connector 321 and the second connector 336. One end of the cylindrical pin is connected to the first handle 3211, and the other end extends toward the second connector 336 and is inserted into the pin hole of the second connector 336.

[0134] Before installing the probe mechanism 33, the cylindrical pin can be pulled out of the first connector 321 through the first handle 321. After the second connector 336 is inserted into the first connector 321 and the pin holes of the second connector 336 and the first connector 321 are aligned, the cylindrical pin can be inserted into the pin holes of the second connector 336 and the first connector 321 through the first handle 3211 to fix the second connector 336 in the first connector 321, so that the probe mechanism 33 can be fixed to the bottom of the lifting mechanism 32.

[0135] In an embodiment of the present application, a fixing member is provided on the first connector, which can fix the second connector to stably install the probe mechanism on the lifting mechanism, thereby improving the stability of the probe mechanism and further improving the accuracy of the test results.

[0136] In some embodiments, a stopper 3214 may be provided on the first connector 321 to limit the insertion position of the second connector 336. As shown in FIG7 , the stopper 3214 may be a baffle integrally formed with the first connector 321. During the insertion of the second connector 336 into the first connector 321, the baffle may limit the insertion position of the second connector 336, thereby facilitating quick installation of the probe mechanism 33 at the bottom of the lifting mechanism 32.

[0137] In some embodiments, a first in-place detection sensor 3213 is provided on the first connector 321 , and the first in-place detection sensor 3213 is used to detect whether the second connector 336 is plugged in place.

[0138] FIG8 shows a side view of a first connector provided in some embodiments of the present application. As shown in FIG8 , a first in-place detection sensor 3213 is provided in the first connector 321. The first in-place detection sensor 3213 can be a proximity switch, and the proximity switch is electrically connected to the controller. When the second connector 336 is inserted into the corresponding first connector 321 and plugged into place, the proximity switch can be triggered to close, and the proximity switch can send a closing signal to the controller. Conversely, when the second connector 336 is removed from the first connector 321 or the second connector 336 is not plugged into place, the proximity switch is in an off state, and the proximity switch can send a disconnection signal to the controller.

[0139] After receiving the closing signal, the controller can determine that the second connector 336 is properly plugged in and can start testing the battery. After receiving the opening signal, the controller can determine that the second connector 336 is not properly plugged in and can prohibit the battery testing device from starting and running.

[0140] It can be understood that the first in-position detection sensor may include but is not limited to the proximity switch in the above example.

[0141] In the embodiment of the present application, a position detection sensor is provided in the first connector, which can facilitate the battery testing device to obtain the installation status of the probe mechanism and effectively test the battery according to the installation status of the probe mechanism.

[0142] In some embodiments, the probe mechanism 33 further includes a first electrical connector 337 and a second electrical connector 338. The plurality of first probes 331 are electrically connected to the first electrical connector 337, and the second electrical connector 338 is electrically connected to a circuit in the battery testing device. The first electrical connector 337 is electrically connected to the second electrical connector 338.

[0143] As shown in Figure 4, the first electrical connector 337 can be a receptacle of a Harding connector, and the second electrical connector 338 can be a plug of a Harding connector. The receptacle and the plug can be plugged together to form a Harding connector. The receptacle can be fixedly mounted on the side of the adapter bracket 332 facing away from the first guide rail 334, and the plug can be plugged into the receptacle.

[0144] The first probe 331 on each first connector 339 is electrically connected to a terminal in the socket via a wire. The terminal on the plug is electrically connected to a relay in the circuit. When the plug is plugged into the socket, the first probe 331 can be electrically connected to the circuit.

[0145] It should be noted that the first electrical connector 337 and the second electrical connector 338 may also be other types of electrical connectors, including but not limited to Harding connectors.

[0146] Since the first electrical connector 337 and the second electrical connector 338 are detachable, when the probe mechanism 33 needs to be removed from the battery testing device, the first electrical connector 337 and the second electrical connector 338 can be separated first to disconnect the electrical connection between the probe mechanism 33 and the circuit, and then the probe mechanism 33 can be removed from the battery testing device.

[0147] On the contrary, during the installation of the probe mechanism 33 , the probe mechanism 33 may be first installed in the battery testing device, and then the second electrical connector 338 may be plugged into the first electrical connector 337 , so as to quickly establish an electrical connection between the probe mechanism 33 and the circuit.

[0148] As shown in FIG3 , the lifting mechanism 32 is provided with a wiring mechanism, such as a tank chain 328, which is used to route the wiring between the second electrical connector 338 and the circuit. Multiple tank chains 328 can be provided in the lifting mechanism 32 to facilitate routing wiring of different voltage levels in different tank chains.

[0149] In an embodiment of the present application, the electrical connection between the probe mechanism and the battery testing device can be quickly established through the plug-in mating of the first electrical connector and the second electrical connector, and the electrical connection between the probe mechanism and the battery testing device can also be quickly disconnected, thereby greatly reducing the disassembly and installation time of the probe mechanism.

[0150] In some embodiments, multiple first connectors 339 are detachably connected to the first guide rail 334; a first connector 3310 is provided on the first connector 339, and the first connector 3310 is electrically connected to the first probe 331 installed on the first connector 339; the battery testing device includes a second connector 3311 corresponding to the first connector 3310, the second connector 3311 is detachably connected to the corresponding first connector 3310, and the second connector 3311 is electrically connected to the circuit in the battery testing device.

[0151] Figure 9 shows a side view of a first connector provided in some embodiments of the present application. As shown in Figure 9, the first connector 339 can be a strip-shaped connecting block, including a first bend 3391 at one end of the first connector 339 and a second bend 3392 at the other end. The first bend 3391 and the second bend 3392 are located on the same side of the first connector 339.

[0152] The first connector 3310 is disposed on a side of the first bend 3391 that is close to the second bend 3392, and the second connector 3311 is disposed on a side of the first bend 3391 that is away from the second bend 3392. A through hole is provided in the first bend 3391, through which the first connector 3310 passes to detachably connect to and electrically connect to the second connector 3311. Multiple first probes 331 are disposed on the second bend 3392, for example, two, three, or four first probes 331 may be provided.

[0153] In actual application, a wire can be set between the first probe 331 and the first connector 3310, one end of the wire is welded to the first probe 331, and the other end is welded to the first connector 3310 to achieve electrical connection between the first probe 331 and the first connector 3310, thereby achieving electrical connection between the first probe 331 and the second connector 3311.

[0154] In some embodiments, a second connecting portion 3393 is provided on the first connecting member 339 , a first slideway 3341 matching the second connecting portion 3394 is provided on the first guide rail 334 , and the second connecting portion 3393 is slidably connected to the first slideway 3341 .

[0155] Figure 10 shows a schematic diagram of the installation of a first connector provided in some embodiments of the present application. As shown in Figure 10, the first connector 339 is provided with a second connector portion 3393, which is located between the first bend portion 3391 and the second bend portion 3392. The second connector portion 3393 is provided with a screw hole 3394. The first guide rail 334 is provided with a first slideway 3341 that matches the shape and size of the second connector portion 3393. The second connector portion 3393 is located within the first slideway 3341, and the second connector portion 3393 can drive the first connector 339 to slide within the first slideway 3341.

[0156] After the first connecting member 339 is installed on the first guide rail 334 , a screw may be provided in the screw hole 3394 so as to abut against the side wall of the first slideway 3341 to fix the first connecting member 339 on the first guide rail 334 .

[0157] When the first connector 339 fails, for example, when the first probe 331 on the first connector 339 is damaged and cannot be used normally, the first connector 3310 and the second connector 3311 on the first connector 339 can be separated first, and then the failed first connector 339 can be removed from the first guide rail 334. Then, the normal first connector 339 can be installed on the first guide rail 334, and the corresponding second connector 3311 can be connected to the first connector 3310, so that the failed first connector 339 in the probe mechanism 33 can be quickly replaced.

[0158] In which, when a first electrical connector 337 and a second electrical connector 338 are set in the probe mechanism, the first probe 331 can be connected to the first electrical connector 337 through the electrically connected first connector 3310 and second connector 3311, so that it can be electrically connected to the circuit through the plug-in mating first electrical connector 337 and second electrical connector 338.

[0159] It should be understood that the first connecting member and the first guide rail may also be detachably connected in other ways, and specific ways of detachably connecting may include but are not limited to the above examples.

[0160] In this embodiment, the position of the first connector on the first guide rail is adjustable, which makes it easy for staff to adjust the distance between two adjacent first connectors on the first guide rail, so that the probe mechanism can be used for battery cells of different thicknesses, thereby improving the compatibility of the battery testing device.

[0161] In an embodiment of the present application, the first connecting member and the first guide rail are detachably connected, and the first probe and the circuit are electrically connected through the detachably connected first connector and the second connector. When the first connecting member fails, the faulty first connecting member can be quickly replaced, which facilitates the staff to repair the probe mechanism.

[0162] In some embodiments, a temperature sensor 3312 is provided on at least a portion of the first connector 339 , and the temperature sensor 3312 is used to detect the temperature of the battery cell.

[0163] Figure 11 shows a side view of another first connector provided in some embodiments of the present application. As shown in Figure 11 , in addition to the first probe 331 , the first connector 339 is also provided with a temperature sensor 3312 , which may be a temperature probe.

[0164] In which, multiple wiring terminals can be respectively set on the first connector 3310 and the second connector 3311, the first probe 331 can be electrically connected to the first electrical connector 337 through a pair of wiring terminals, and the temperature probe can be electrically connected to the first electrical connector 337 through another pair of wiring terminals. Then, the first probe 331 can be electrically connected to the circuit through the first electrical connector 337 and the second electrical connector 338 that are plugged in, and the temperature probe can be electrically connected to the controller through the first electrical connector 337 and the second electrical connector 338 that are plugged in.

[0165] During the battery test, the temperature probe can contact the electrode terminals of the battery cell, sample the temperature of the battery cell, and send the sampled temperature value to the controller. Specific types of temperature sensors may include but are not limited to the above examples.

[0166] It should be noted that the probe mechanism includes multiple first connectors, some of which are provided with temperature sensors. Multiple temperature sensors can be set on multiple first connectors at different positions to detect the temperature of battery cells at different positions in the battery.

[0167] In the embodiment of the present application, temperature sensors are provided on some of the first connectors, and the temperature of the battery cells in the battery can be detected by the temperature sensors, so as to facilitate detection of the characteristic point temperature of the battery during the battery testing process.

[0168] In some embodiments, a second in-position detection sensor 3313 is provided on at least a portion of the first connecting member 339 , and the second in-position detection sensor 3313 is used to detect whether the probe mechanism 33 moves to the target position.

[0169] Figure 12 shows a side view of another first connector provided in some embodiments of the present application. As shown in Figure 12, in addition to the first probe 331, the first connector 339 is also provided with a second in-position detection sensor 3313. The second in-position detection sensor 3313 is, for example, a proximity switch, including a trigger probe 33131 and a sensing component 33132. The trigger probe 33131 is arranged in parallel with the first probe 331.

[0170] The sensing component 33132 can also be electrically connected to the first electrical connector 337 through a pair of wiring terminals in the first connector 3310 and the second connector 3311, and then electrically connected to the controller through the first electrical connector 337 and the second electrical connector 338 that are plugged in.

[0171] The target position may be the stopping position of the probe mechanism 33 during its descent. When the probe mechanism 33 moves to the target position, the first probe 331 effectively contacts the electrode terminal in the battery without damaging the first probe 331. The target position may be flexibly set according to actual needs.

[0172] In the process of the lifting mechanism 32 driving the probe mechanism 33 to move, when the probe mechanism 33 moves to the target position, the trigger probe 33131 contacts the battery cell, causing the trigger probe 33131 to move toward the direction close to the first connector 3310, and the trigger sensing component 33132 sends a stop signal to the controller. After receiving the stop signal, the controller controls the lifting mechanism 32 to stop running.

[0173] It should be noted that the probe mechanism includes multiple first connecting parts 339, and some of the multiple first connecting parts 339 are provided with second in-place detection sensors 3313. Multiple second in-place detection sensors 3313 can be set on multiple first connecting parts 339 at different positions.

[0174] In an embodiment of the present application, an in-place detection sensor is provided on part of the first connecting member. The in-place detection sensor can detect the position of the probe mechanism, thereby reducing the probability of hard contact between the probe mechanism and the battery, thereby effectively protecting the probe mechanism.

[0175] In some embodiments, the probe mechanism 33 further includes a second connecting member 3314 mounted on the first connecting portion 333 , and a second probe 3319 on the second connecting member 3314 is used to contact the end plate of the battery.

[0176] Figure 13 shows a partial schematic diagram of a probe mechanism provided in some embodiments of the present application. As shown in Figure 13, the probe mechanism 33 also includes a second connecting member 3314, which is located between the two first guide rails 334 and is mounted on the side of the second guide rail 335 near the first guide rail 334 via a structural member 3318.

[0177] The second connector 3314 and the first connector 339 may have the same structure. One or more second probes 3319 are provided on the second connector 3314. The second connector 3314 and the first connector 339 are located at the same or a similar height. During testing, when the probe mechanism 33 reaches the target position, the second probes 3319 may contact the end plates of the battery.

[0178] Similarly, the second connecting member 3314 is provided with a detachably connected first connector 3310 and a second connector 3311, and the second probe 3319 can first be connected to the first electrical connector 337 through the electrically connected first connector 3310 and the second connector 3311, and then electrically connected to the circuit through the plug-in mating first connector 337 and the second connector 338.

[0179] The second connector 3314 may be provided on one of the first connectors 333, or two second connectors 3314 may be provided on each of the two first connectors 333. The specific connection relationship between the first connector 333 and the second connector 3314 may include but is not limited to the above examples.

[0180] During the battery test, the controller may connect the battery cells in the battery in series through a circuit, and then connect the series-connected battery cells and end plates to both ends of a multimeter to perform an insulation test on the battery.

[0181] In the embodiment of the present application, when the probe mechanism includes a second probe, the battery testing device can perform insulation testing on the battery, thereby expanding the application range of the battery testing device.

[0182] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
