Description

Technical Field

[0001] The present disclosure relates to the technical field of battery voltage detection, and in particular to a battery cell voltage detection device for recycling retired batteries. Background Art

[0002] The new energy electric vehicle market continues to mature. After the power batteries of new energy electric vehicles are retired, many power batteries still have residual capacity, which can be downgraded to energy storage, backup power and other scenarios, so as to maximize the use of surplus energy. The cascade utilization of power batteries is to conduct necessary inspections, classification, disassembly, battery repair or reorganization of retired power batteries into cascade products so that they can be applied to other fields. At present, cascade utilization products have been applied in the fields of energy storage and backup power. However, before the retired batteries are recycled, the cell voltage needs to be tested to classify the retired batteries with and without recycling value, so as to ensure the safety of the disassembly of the retired batteries for recycling.

[0003] Prior art, such as Chinese patent document CN219641888U, discloses a second-life battery voltage detection device, including a probe, a base plate, and two L-shaped support rods. A strip-shaped through hole is opened on the horizontal rod of the L-shaped support rod, and a connecting bolt is arranged in the strip-shaped through hole. The two L-shaped support rods are detachably connected by the connecting bolts. A cylinder is fixed on the top of the vertical rods of the two L-shaped support rods, and the output shaft of the cylinder is connected to the probe. The two probes are electrically connected to a voltmeter, and one of the L-shaped support rods is connected to the base plate.

[0038] See also Figures 1 to 7 In order to better understand the battery cell voltage detection device 10 for recycling retired batteries disclosed in the present invention, the battery cell voltage detection device 10 for recycling retired batteries is further explained below:

[0039] The cell voltage detection device 10 for recycling retired batteries in one embodiment includes a frame 100, a detection component 300, a drive component 400 and a sorting component 500. The frame 100 is provided with a vertical loading cavity 101 for stacking retired batteries 200. The frame 100 is formed with a to-be-tested platform 110, which is located below the vertical loading cavity 101. The detection assembly 300 includes a detection platform 310, a positive and negative electrode detection component 320 and a voltmeter 330; the detection platform 310 is arranged in parallel to one end of the platform to be inspected 110, the positive and negative electrode detection component 320 is arranged on the side of the detection platform 310 away from the frame 100, the voltmeter 330 is electrically connected to the positive and negative electrode detection component 320, and the detection ends of the positive and negative electrode detection component 320 are arranged toward the positive and negative electrodes of the retired battery 200 located on the detection platform 310; the first material guiding slope 3110 and the second material guiding slope 3120 are respectively provided at both ends of the detection platform 310.

[0040] In one embodiment, the driving assembly 400 includes a telescopic driving member 410 and a push plate 420, and the push plate 420 is installed and fixed to the power telescopic end of the telescopic driving member 410; the push plate 420 performs linear reciprocating motion toward the positive and negative pole detection member 320 under the action of the telescopic driving member 410.

[0041] In one embodiment, the sorting component 500 includes a U-shaped rotating toggle member 510, which is located above the detection platform 310, and the clamping end of the U-shaped rotating toggle member 510 is used to make the retired battery 200 slide away from the detection platform 310 along the first material guide slope 3110 or the second material guide slope 3120.

[0042] In the present embodiment, the retired batteries 200 stacked in the vertical loading chamber 101 can fall to the inspection platform 110 by their own weight, and then the telescopic driving member 410 drives the pushing plate 420 to push the retired batteries 200 located on the inspection platform 110 to the inspection platform 310, so that the positive and negative electrodes of the retired batteries 200 are respectively in contact with the detection ends of the positive and negative electrode detection members 320, and then the voltmeter 330 performs voltage detection of the retired batteries 200, thereby realizing the automation of the voltage detection of the retired batteries 200, thereby effectively improving the efficiency of the voltage detection of the retired batteries 200.

[0043] Furthermore, when the retired battery 200 has completed voltage testing, the clamping end of the U-shaped rotating toggle member 510 can enable the retired battery 200 on the testing platform 310 to slide off the testing platform 310 along the first material guide slope 3110 or the second material guide slope 3120, thereby separating the retired batteries 200 with recycling value from those without recycling value, effectively saving the time for manual testing and screening, thereby achieving efficient sorting of the retired batteries 200.

[0044] like Figures 1 to 4 As shown, in one embodiment, the cell voltage detection device 10 for the recycled battery further includes a first synchronous clamping group 600 and a second synchronous clamping group 700, which are sequentially installed and fixed at the bottom of the vertical material placement chamber 101 in the vertical direction, and the second synchronous clamping group 700 is located above the first synchronous clamping group 600. It can be understood that in this embodiment, the first synchronous clamping group 600 and the second synchronous clamping group 700 are two-claw synchronous clamps in a group of two, respectively, and the two-claw synchronous clamps are used to clamp the retired battery 200. And the voltmeter 330, the telescopic drive member 410 and the two-claw synchronous clamp are electrically connected to the control panel 360 respectively.

[0045] Specifically, the first synchronous clamping group 600 can be divided into a first two-claw synchronous clamp at the left end and a first two-claw synchronous clamp at the right end, and the second synchronous clamping group 700 can be divided into a second two-claw synchronous clamp at the left end and a second two-claw synchronous clamp at the right end, wherein all two-claw synchronous clamps are electrically connected to the control panel 360. More specifically, the control panel 360 simultaneously controls the first two-claw synchronous clamp at the left end and the first two-claw synchronous clamp at the right end to clamp the retired batteries 200 at the bottom of the vertical material placement chamber 101, while the second two-claw synchronous clamp at the left end and the second two-claw synchronous clamp at the right end clamp the retired batteries 200 at the second layer. When the first two-claw synchronous clamp at the left end and the first two-claw synchronous clamp at the right end are released at the same time, the retired batteries 200 of the first layer will fall to the inspection platform 110. At this time, the control panel 360 sends an electrical signal to the telescopic driving member 410, so that the telescopic driving member 410 drives the push plate 420 to push the retired batteries 200 located on the inspection platform 110 to the inspection platform 310 for inspection; synchronously, the second two-claw synchronous clamp at the left end and the second two-claw synchronous clamp at the right end are released at the same time, and the retired batteries 200 of the second layer and the multiple retired batteries 200 of the upper layer fall to the top of the push plate 420. At this time, the first two-claw synchronous clamp at the left end and the first two-claw synchronous clamp at the right end, as well as the second two-claw synchronous clamp and the second two-claw synchronous clamp at the right end all clamp the retired batteries 200 at the same time. Finally, the telescopic driving member 410 drives the push plate 420 to reset. The above steps are repeated in this way to realize the automatic falling and inspection of the stacked retired batteries 200.

[0046] It should be noted that the two-jaw synchronous clamp is a standard structural component or clamping device known in the relevant technical field.

[0047] like Figure 1 to Figure 2As shown, in one embodiment, the frame 100 is further provided with a first pressure-bearing guide slot 102 and a second pressure-bearing guide slot 103, and the extension directions of the first pressure-bearing guide slot 102 and the second pressure-bearing guide slot 103 are parallel to the extension direction of the power extension end of the telescopic driving member 410; one end of the push plate 420 is slidably connected to the first pressure-bearing guide slot 102, and the other end of the push plate 420 is slidably connected to the second pressure-bearing guide slot 103. It can be understood that in other embodiments, the first pressure-bearing guide slot 102 and the second pressure-bearing guide slot 103 are symmetrically arranged. In this embodiment, the power extension end of the telescopic driving member 410 can drive the push plate 420 to slide and connect with the first pressure-bearing guide slot 102 and the second pressure-bearing guide slot 103, respectively, so as to ensure the smoothness of the process of the push plate 420 pushing the retired battery 200 to the detection platform 310, which is conducive to improving the efficiency of the voltage detection of the retired battery 200.

[0048] like Figure 1 to Figure 2 As shown, in one embodiment, the detection component 300 also includes a display 340, an indicator light 350 and a control panel 360. The display 340 is located on the side of the detection platform 310 away from the rack 100. The indicator light 350, the control panel 360 and the voltmeter 330 are respectively installed and fixed on the top of the display 340; the display 340 and the indicator light 350 are respectively electrically connected to the control panel 360. It can be understood that the control panel 360 is the control system of the battery cell voltage detection device 10 for the cascade utilization of retired batteries to ensure the coordinated operation between the various components. Specifically, the control panel 360 can be a PLC control system.

[0049] like Figures 1 to 7 As shown, in one embodiment, the positive and negative pole detection component 320 includes a positive pole detection needle 3210, a negative pole detection needle 3220, a first cylinder component 3230 and a second cylinder component 3240; the first cylinder component 3230 and the second cylinder component 3240 are both installed on the back of the display 340, the positive pole detection needle 3210 is installed on the telescopic main shaft of the first cylinder component 3230, and the positive pole detection needle 3210 is electrically connected to the voltmeter 330; the negative pole detection needle 3220 is installed on the telescopic main shaft of the second cylinder component 3240, and the negative pole detection needle 3220 is electrically connected to the voltmeter 330. In one embodiment, the cell voltage detection device 10 for recycling retired batteries further includes a limiting partition 800, which is disposed between the detection platform 310 and the display 340, and the limiting partition 800 is provided with a first through hole 801 and a second through hole 802, the detection end of the positive electrode detection needle 3210 passes through the first through hole 801 and abuts against the positive electrode of the retired battery 200, and the detection end of the negative electrode detection needle 3220 passes through the second through hole 802 and abuts against the negative electrode of the retired battery 200.

[0050] It can be understood that the telescopic driving member 410 drives the push plate 420 to push the retired battery 200 located on the inspection platform 110 to the inspection platform 310, and the corresponding first cylinder member 3230 also synchronously drives the detection end of the positive electrode detection needle 3210 on the telescopic main shaft to abut against the positive electrode of the retired battery 200, and the second cylinder member 3240 also synchronously drives the detection end of the negative electrode detection needle 3220 on the telescopic main shaft to abut against the negative electrode of the retired battery 200.

[0051] like Figure 3 , Figure 6 and Figure 7 As shown, in one embodiment, the diameter of the positive pole detection needle 3210 is smaller than the diameter of the first through hole 801, and the diameter of the negative pole detection needle 3220 is smaller than the diameter of the second through hole 802; the diameter of the telescopic main shaft of the first cylinder part 3230 is larger than the diameter of the first through hole 801, and the diameter of the telescopic main shaft of the second cylinder part 3240 is larger than the diameter of the second through hole 802.

[0052] It can be understood that the diameter of the telescopic main shaft of the first cylinder part 3230 is larger than the first through hole 801, and the diameter of the telescopic main shaft of the second cylinder part 3240 is larger than the second through hole 802, so that the limiting partition 800 can ensure that the detection end of the positive detection needle 3210 and the detection end of the negative detection needle 3220 are smoothly abutted against the corresponding positive and negative electrodes of the retired battery 200, and at the same time effectively prevent the telescopic main shaft of the cylinder part from accidentally colliding with the positive and negative electrodes of the retired battery 200, thereby improving the detection accuracy of the battery cell voltage detection device 10 for the recycling of retired batteries.

[0053] like Figures 3 to 7 As shown, in one embodiment, the sorting assembly 500 further includes a rotating motor 520, which is mounted and fixed on the limiting partition 800, and the U-shaped rotating toggle member 510 is fixedly connected to the rotating shaft of the rotating motor 520. In one embodiment, the movement direction perpendicular to the push plate 420 is the width direction of the detection platform 310, the width direction is parallel to the plane where the detection platform 310 is located, and the width of the detection platform 310 is smaller than the dimension of the retired battery 200 parallel to the width direction. When the retired battery 200 is detected on the detection platform 310, the two ends of the retired battery 200 are respectively located above the first material guiding slope 3110 and above the second material guiding slope 3120.

[0054] It can be understood that the first guide slope 3110 and the second guide slope 3120 are set at both ends of the detection platform 310 so that the width of the detection platform 310 is smaller than the dimension of the retired battery 200 parallel to the width direction, so that the rotating motor 520 can drive the U-shaped rotating toggle 510 to rotate and tilt clockwise or counterclockwise according to the voltage data result detected by the voltmeter 330. In this embodiment, the retired battery 200 (capacity between 20-80%) with a measured voltage greater than the set value has a cascade utilization value. Specifically, at this time, the U-shaped rotating toggle 510 will rotate counterclockwise by 15° to 60°, so that the retired battery 200 after the test is rotated and tilted, and finally slides down along the first guide slope 3110. On the contrary, if the measured voltage is less than the set value, it does not have a cascade utilization value. At this time, the retired battery 200 will be rotated clockwise by 15° to 60° by the U-shaped rotating toggle 510, and finally slides down along the second guide slope 3120.

[0055] like Figure 5 As shown, in one embodiment, the cell voltage detection device 10 for recycling retired batteries further includes a first conveyor belt 900 and a second conveyor belt 1000, wherein the first conveyor belt 900 extends to the first guide slope 3110, and the second conveyor belt 1000 extends to the second guide slope 3120. It can be understood that the retired batteries 200 with recycling value slide along the first guide slope 3110 to the first conveyor belt 900, while the retired batteries 200 without recycling value slide along the second guide slope 3120 to the second conveyor belt 1000, so that the voltage of the retired batteries 200 can be accurately detected and transported and sorted automatically and efficiently, greatly saving the time and energy consumed by manual labor.

[0056] It should be noted that the cell voltage detection device for recycling retired batteries disclosed in the present invention only protects the electrical signal connection relationship between each component and the control panel, while the automatic control method of the cell voltage detection device for recycling retired batteries belongs to the prior art and is not within the protection scope of the present invention.

[0057] Compared with the prior art, the present invention has the following advantages, including but not limited to:

[0058] 1. The retired batteries 200 stacked in the vertical loading chamber 101 can fall to the inspection platform 110 by their own weight, and then the telescopic driving member 410 drives the push plate 420 to push the retired batteries 200 on the inspection platform 110 to the inspection platform 310, so that the positive and negative electrodes of the retired batteries 200 are respectively in contact with the detection ends of the positive and negative electrode detection members 320, and then the voltmeter 330 performs voltage detection of the retired batteries 200, thereby realizing the automation of the voltage detection of the retired batteries 200, thereby effectively improving the efficiency of the voltage detection of the retired batteries 200.

[0059] 2. When the retired battery 200 has completed voltage testing, the clamping end of the U-shaped rotating toggle member 510 can make the retired battery 200 on the testing platform 310 slide off the testing platform 310 along the first material guiding slope 3110 or the second material guiding slope 3120, thereby separating the retired batteries 200 with cascade utilization value from those without cascade utilization value, effectively saving the time of manual testing and screening, thereby realizing efficient sorting of the retired batteries 200.

[0060] 3. The diameter of the telescopic main shaft of the first cylinder part 3230 is larger than the first through hole 801, and the diameter of the telescopic main shaft of the second cylinder part 3240 is larger than the second through hole 802, so that the limiting partition 800 can ensure that the detection end of the positive detection needle 3210 and the detection end of the negative detection needle 3220 are smoothly abutted against the corresponding positive and negative electrodes of the retired battery 200, and at the same time effectively prevent the telescopic main shaft of the cylinder part from accidentally colliding with the positive and negative electrodes of the retired battery 200, thereby improving the detection accuracy of the battery cell voltage detection device 10 for the cascade utilization of retired batteries.

[0061] 4. The retired batteries 200 with recycling value slide along the first guide slope 3110 to the first conveyor belt 900, and the retired batteries 200 without recycling value slide along the second guide slope 3120 to the second conveyor belt 1000. In this way, the voltage of the retired batteries 200 can be accurately detected and transported and sorted efficiently, which greatly saves the time and energy consumed by labor.

[0062] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the disclosed patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the disclosed patent shall be subject to the attached claims.
