Description

Technical Field

[0001] The utility model relates to the field of battery capacity measurement, in particular to a battery remaining capacity rapid measurement device. Background Art

[0002] A device that converts chemical energy into electrical energy is called a chemical battery, generally referred to as a battery. After discharge, the internal active substances can be regenerated by charging - the electrical energy is stored as chemical energy; when it is necessary to discharge, the chemical energy is converted into electrical energy again. This type of battery is called a storage battery, also known as a secondary battery or a lead-acid storage battery.

[0003] After a battery has been used for a long time, in order to understand its reserve capacity, that is, the remaining energy, it is necessary to measure the remaining capacity. According to the current voltage and the discharge curve of the battery, the remaining capacity can be calculated by a simple linear difference or by using a more complex algorithm. A common method is to compare the current voltage with the known voltage-capacity data point and calculate the corresponding remaining capacity. When using existing measuring devices, most of them connect the battery to the battery capacity detector through a power clip. However, the existing measuring devices are inconvenient to use. After being connected to the detector, the battery is easily disturbed by external factors and is driven to shake, which seriously affects the measurement accuracy.

[0004] In order to make a more accurate comparison, a Chinese patent with publication number CN116338491A discloses a battery remaining capacity measuring device, including a measuring box, a fixed box slidably installed inside the measuring box, a clamping mechanism for clamping the battery is arranged inside the fixed box, a lifting mechanism for changing the position of the fixed box inside the measuring box is arranged on the bottom side of the measuring box, sealing plates are symmetrically installed on both sides of the upper end of the measuring box, and a measuring mechanism for measuring the battery capacity is arranged on the sealing plates; when in use, the height of the fixed box is adjusted up and down by turning the handle, and then the battery is installed in the fixed box through the clamping mechanism, and then the power clamp in the measuring mechanism is clamped on the positive and negative ends of the battery, and finally the remaining capacity of the battery is displayed on the display screen.

[0005] However, the above-mentioned measuring device still has some shortcomings in actual use: 1. The above-mentioned device adjusts the position of the battery to be tested by lifting the fixed box, and then only drives the clamping plate to clamp and install the battery through the clamping springs on both sides of the fixed box. During use, the axial clamping force generated by the clamping springs on both sides needs to be formed after the outer side of the battery placed in the fixed box squeezes and pushes the clamping springs. However, if the two ends of the battery placed in the fixed box are not sufficient to push and squeeze the clamping springs on both sides at the same time, then the clamping springs and the clamping plate are not sufficient to completely limit the battery to be installed in the fixed box, and the effect of limiting and fixing the smaller-sized battery cannot be achieved.

[0006] 2. Since the above device needs to place the battery to be detected into the fixed box to form the effect of clamping and limiting it, however, when the battery to be detected is relatively long or high, only the part of the detected battery located inside the fixed box can be limited by the fixed box at this time, and the situation where the battery is driven by external force interference cannot be completely avoided at this time.

[0007] Therefore, under the above-stated viewpoints, there is still room for improvement in the existing measuring device. Summary of the Invention

Specific embodiments

[0030] The following will Figure 1 be described in detail with reference to the appended Figure 7 drawings for the embodiments of the present utility model, but the present utility model can be implemented in many different ways defined and covered by the claims.

[0031] The embodiment of the present application discloses a device for quickly measuring the remaining capacity of a battery. It should be noted that this battery remaining capacity measuring device is mainly applied in the process of measuring the remaining energy of a battery, and in terms of technical effects, it realizes the detection and recording of the remaining energy data of the battery to be detected; especially after connecting this device to the battery to be detected, the limiting unit is used to clamp and limit the battery to increase the stability during battery detection and尽量 avoid the detection data error caused by the晃动 of the battery to be detected; further, this battery remaining capacity measuring device also adjusts the return frame to clamp and limit batteries of different sizes, thereby increasing the applicability of this device.

[0032] Embodiment 1: Refer to Figure 1 and Figure 2 As shown, a battery remaining capacity rapid measurement device comprises a detection box 1, a receiving box 10, a test unit 2 and a limit unit 3. The detection box 1 is a hollow shell structure formed by rotating and splicing at least two receiving boxes 10, and any one of the receiving boxes 10 is installed with a test unit 2 for testing the battery, and the other receiving box 10 is installed with a limit unit 3 for limiting the battery. Casters are installed on the outer surface of the detection box 1 for horizontal movement of the detection box 1 on the ground to increase the mobility of the device. A pull rod is also slidably installed on the outer side of one of the receiving boxes 10 to facilitate the staff to drag the device to move; after the two receiving boxes 10 are rotated and spliced ​​into the detection box 1, the two receiving boxes 10 are fixed together by multiple spring buckles (not shown in the figure) arranged on the outer side. When in use, the battery to be tested is clamped and limited by the limit unit 3 in one of the receiving boxes 10, and then the residual energy data of the battery is detected and measured by the test unit 2 in the other receiving box 10.

[0033] It should be noted that the test unit 2 mainly includes an electronic load meter, an electronic internal resistance meter, a charging facility, a keyboard-screen integrated touch screen, a switch, and a plurality of positive and negative terminals, which are electrically connected to each other through a circuit integrated board and electrical wires and installed in one of the containing boxes 10, and the above-mentioned test unit 2 is all conventional existing technology.

[0034] The electronic load meter mainly increases or decreases the load gradually by adjusting the settings of the electronic load meter until the required test parameters are reached. At this time, the electronic load meter will simulate the load conditions and record the corresponding data while monitoring the power output, and display and record its data on the keyboard screen integrated touch screen.

[0035] The electronic internal resistance meter mainly sets the test parameters of the internal resistance meter, such as test current, test time, etc., according to the test requirements. The instrument will measure the voltage change of the power supply connected to the test battery by applying a load or adjusting the current, and calculate the corresponding internal resistance value, and display and record the data on the integrated touch screen of the keyboard screen.

[0036] The keyboard-screen integrated touch screen is also an all-in-one computer, which is mainly used to detect and calculate the test data of the electronic load meter and the electronic internal resistance meter. It has built-in measurement software. The main implementation methods of the measurement software are:

[0037] 1. Battery internal resistance measurement record:

[0038] (1) Data is read directly from the device.

[0039] (2) The records are read every ten seconds and saved to the sqlite database.

[0040] (3) After the test is completed, the average value is calculated and displayed.

[0041] 2. Add a residual value evaluation calculation function to the initial interface, add a button, enter the initial value of the battery's factory capacity to calculate the ratio of the remaining energy to the initial value (percentage), and calculate the battery health status value SOH.

[0042] 3. Intelligent charging, directly charging to the battery charging stop voltage.

[0043] (1) Calculate the charge stop voltage and discharge stop voltage using the information on the battery label.

[0044] (2) New charging mode, automatically charging to the charging stop voltage.

[0045] 4. Fast test mode, by adjusting the electronic load to double the discharge current to achieve a corresponding reduction in the test cycle (speed up the test) (the goal is to reduce the speed to 1 hour).

[0046] Reference Figures 2 to 4 As shown, the limiting unit 3 is used to limit and clamp the battery to be tested; specifically, the limiting unit 3 includes a return frame 30, a connecting portion 31 and an adjusting member 32, the return frame 30 is slidably arranged in the accommodating box 10, the two vertical sections of the return frame 30 are telescopic structures, and sliding grooves are symmetrically opened on the two horizontal sections of the return frame 30, the connecting portion 31 is slidably arranged in the sliding groove, the battery interface 311 is installed on the connecting portion 31, and the connecting portion 31 is installed on the horizontal section of the return frame 30 through the adjusting member 32.

[0047] During use, the circular frame 30 is extended and contracted accordingly according to the size of the battery to be measured, and the position of the connecting part 31 is adjusted by the adjusting member 32, so that the connecting part 31 can further limit and clamp the battery to be measured, thereby improving the stability of the battery when being measured and reducing the error of the measurement data.

[0048] Reference Figure 4 As shown, the connection part 31 includes a bending clamp 310 symmetrically slidably arranged in the sliding groove, the horizontal section of the bending clamp 310 is limitedly connected in the sliding groove, and the battery interface 311 is symmetrically installed on the horizontal section of the bending clamp 310. The movement of the bending clamp 310 drives the connected battery interface 311 to move, and the battery interface 311 on the two bending clamps 310 is respectively connected to the positive electrode terminal and the negative electrode terminal in another storage box 10 through electrical wires. When in use, by adjusting the position of the bending clamp 310, that is, adjusting the position of the battery interface 311 connected thereto, it is suitable for positive and negative electrodes at different positions on different batteries, thereby realizing charging and discharging tests on the battery that needs to be measured.

[0049] Reference Figure 4 As shown, an adjusting slider 33 is also slidably arranged in the sliding groove and is located between the two bent clamps 310. A battery interface 311 is also installed on the adjusting slider 33. The movement of the adjusting slider 33 drives the connected battery interface 311 to move. When in use, if the positive and negative test terminals of the battery to be tested are not located on the same side at the same time, but are distributed on both sides, the position of the battery interface 311 connected thereto is adjusted by adjusting the slider 33. At this time, the battery interface 311 connected to the adjusting slider 33 is connected to the positive and negative test terminals of the battery to complete subsequent measurements, thereby achieving the effect of measuring different types of batteries.

[0050] Example 2: Reference Figure 4 and Figure 5 As shown, on the basis of the first embodiment, due to the size limitation of the storage box 10, for some batteries of larger size that are not convenient to be completely placed into the storage box 10 for measurement, a telescopically adjustable circular frame 30 is provided, and the circular frame 30 includes a bidirectional telescopic rod 300, a limit connecting rod 301 and a convex plate 302. The middle part of the vertical section of the circular frame 30 is provided with a bidirectional telescopic rod 300 connected to the storage box 10, and the opposite sides of the two telescopic sections of the bidirectional telescopic rod 300 are rotatably connected with the limit connecting rod 301, and the outer side surface of the limit connecting rod 301 is symmetrically slidably sleeved with a convex plate 302, and the horizontal sections of the two convex plates 302 respectively constitute the two horizontal sections of the circular frame 30, and the sliding through groove is opened on the horizontal section of the convex plate 302.

[0051] When in use, the larger sized battery test end is placed vertically upward in the containing box 10, and then the bevel plate 302 and the connected limit link 301 are rotated around the rotation axis connected to the bidirectional telescopic rod 300. After the bevel plate 302 is rotated to a certain angle, the bevel plate 302 is slid upward along the outer side surface of the connected limit link 301 so that the battery is located as a whole between the inner sides of the bevel plate 302. Then, by adjusting the position of the bending clamp 310, the two bending clamps 310 in the same sliding groove are moved toward each other until the vertical section of the bending clamp 310 is in contact with the outer side surface of the battery. At this time, all the bending clamps 310 limit and clamp the vertically placed battery to solve the problem of battery instability after placement.

[0052] It should be noted that after a battery with a larger size is vertically placed in the middle position of the accommodation box 10, the positive and negative electrodes of the battery will also change accordingly. If the positive and negative electrode test ends of the vertically placed battery cannot completely correspond to the battery interfaces 311 on the bending clamping plate 310 at this time, the battery interfaces 311 connected to the adjustment slider 33 can be used to connect with the positive and negative electrode test ends of the battery to continue the subsequent measurement, thereby increasing the practicality of this device.

[0053] Referring to Figure 4 As shown, that is, the adjusting member 32 for adjusting the position of the connected bending clamping plate 310. The adjusting member 32 includes a U-shaped connecting plate 320, a bidirectional screw 321, a driven rotating block 322, and a rectangular block 323. A U-shaped connecting plate 320 is provided on the horizontal section of the bending clamping plate 310, and the movement of the U-shaped connecting plate 320 drives the connected bending clamping plate 310 to move; a bidirectional screw 321 is commonly threaded through the two U-shaped connecting plates 320 on the same side of the horizontal section of the loop-shaped frame 30. Two threads with opposite directions are provided on the outer side of the bidirectional screw 321. The rotation of the bidirectional screw 321 drives the connected U-shaped connecting plate 320 to move through the threads on its outer side; a driven rotating block 322 is provided at one end of the bidirectional screw 321 that slides out of the accommodation box 10, and the driven rotating block 322 facilitates the staff to rotate the bidirectional screw 321; a rectangular block 323 connected to the U-shaped plate 302 is rotatably provided at one end of the bidirectional screw 321 located inside the accommodation box 10, and the rectangular block 323 is used to limit and install the connected bidirectional screw 321.

[0054] When in use, when clamping a battery to be detected with a smaller size, by rotating the driven rotating block 322 and the bidirectional screw 321 forward, the U-shaped connecting plate 320 connected to the bidirectional screw 321 moves in an opposite direction through the thread to drive the bending clamping plates 310 to approach each other until the vertical sections of the bending clamping plates 310 abut against the outer side of the battery. At this time, the bending clamping plates 310 limit and fix the position of the battery to increase the stability of the battery during testing; when limiting and clamping a battery with a larger size, by rotating the driven rotating block 322 and the bidirectional screw 321 in the reverse direction, the bidirectional screw 321 drives the bending clamping plates 310 to move away from each other until the vertical sections of the bending clamping plates 310 abut against the outer side of the battery to be detected, thereby achieving the effect of adjusting the position of the bending clamping plates 310 according to the size of the battery to be detected.

[0055] Referring to Figure 1 and Figure 2As shown in the figure, when the position and size of the return frame 30 are adjusted accordingly according to the size of the battery to be detected, since the movement of the return frame 30 drives the connected bent clamping plate 310, C-shaped connecting plate 320 and bidirectional screw 321 to shift at the same time, limit sliding grooves 34 allowing the bidirectional screw 321 to slide are opened on both of the accommodating boxes 10, and the limit sliding grooves 34 on the two accommodating boxes 10 form a complete limit sliding groove 34 after the accommodating boxes 10 are rotated and spliced into a complete detection box 1 to limit the bidirectional screw 321. At this time, the bidirectional screw 321 is slidably inserted into the complete limit sliding groove 34.

[0056] Embodiment 3: Refer to Figure 6 and Figure 7 As shown in the figure, on the basis of Embodiment 1 and Embodiment 2, since the positions of the positive and negative test terminals connected to batteries of different sizes are also different, accordingly, a supporting plate 35 for adjusting the height of the battery placed in the accommodating box 10 is slidably and fittingly arranged in the accommodating box 10, and a weighing module with an upper limit of 10KG is installed in the middle of the supporting plate 35. The weighing module is electrically connected to the testing unit 2; limiting transverse grooves 36 are symmetrically opened on the two opposite sides of the supporting plate 35, lifting frames 37 slidably connected to the bottom of the accommodating box 10 are symmetrically and slidably arranged at the lower end of the supporting plate 35, the upper side ends of the lifting frames 37 are limitedly connected in the limiting transverse grooves 36, and the lifting frames 37 move up and down in the vertical direction to drive the whole supporting plate 35 to move in the vertical direction.

[0057] During use, if there is a height difference between the positive and negative test terminals on the battery and the horizontal section of the return frame 30, the lifting frame 37 is adjusted to drive the supporting plate 35 to move in the vertical direction, so as to drive the battery on the supporting plate 35 to adjust its height, so that the positions of the positive and negative poles on the battery correspond to the positions of the battery interfaces 311 on the bent clamping plate 310 and the adjusting slider 33.

[0058] Refer to Figure 6 and Figure 7 As shown in the figure, both sides of the lifting frame 37 are composed of rotating connecting rods 370 distributed in an "X" shape and a connecting cross plate 371 between the two rotating connecting rods 370 on both sides. The middle parts of the two rotating connecting rods 370 on the same side are rotatably connected by a connecting pin rod, and the two rotating connecting rods 370 swing with the rotating pin rod in the middle as the axis; the lower end of one rotating connecting rod 370 is rotatably connected to the bottom of the accommodating box 10, the upper end of this rotating connecting rod 370 is slidably and limitedly connected in the limiting transverse groove 36, the lower end of the other rotating connecting rod 370 is slidably connected to the bottom of the accommodating box 10 and rotatably connected to the connecting cross plate 371, the upper end of this rotating connecting rod 370 is rotatably connected in the limiting transverse groove 36, and a adjusting screw rod 372 threaded through the accommodating box 10 is rotatably connected to the middle of the connecting cross plate 371.

[0059] In the specific implementation process, when the positive and negative test ends of the battery are located at the lower side of the return frame 30, the adjusting screw 372 is rotated in the forward direction, and the adjusting screw 372 drives the connecting cross plate 371 through the thread on its outer side to move to a position close to the middle of the return frame 30. The connecting cross plate 371 drives the lower end of the rotating connecting rod 370 connected to its two ends to move and rotate. The movement of the rotating connecting rod 370 drives the other rotating connecting rod 370 connected to it to rotate at the same time. At this time, the two rotating connecting rods 370 on the same side rotate to The rotating pin in the middle of the two rotating links 370 is used as an axis to swing together, that is, the two "X"-shaped rotating links 370 are in an upwardly expanded state, and drive the supporting plate 35 as a whole and the battery to be lifted upward; and when the positive and negative test ends of the battery are located on the upper side of the return frame 30, at this time, by rotating the adjusting screw 372 in the opposite direction, the two rotating links 370 will rotate and retract downward at the same time, and drive the supporting plate 35 as a whole and the battery to move downward, thereby achieving the effect of adjusting the height position of the positive and negative test ends of the battery.

[0060] During operation: The first step is to place the battery to be tested on the supporting plate 35, and then adjust the position of the return frame 30 and the connecting part 31 through the adjusting part 32 according to the size specifications of the test battery, and continue to limit and clamp the batteries of different sizes through the adjusted connecting part 31 and the return frame 30 to improve the stability of the test battery during testing.

[0061] Step 2: After adjusting the position of the connecting part 31 by the adjusting member 32, connect the battery interface 311 on the connecting part 31 or the adjusting slider 33 to the positive and negative test terminals of the battery to be tested, and then respectively perform corresponding output and test on the battery through the electronic load meter and the electronic internal resistance meter, and display and record the test data on the touch screen for the convenience of reading and recording by the staff.

[0062] Step 3: By pressing the corresponding calculation button on the touch screen, the staff can calculate the remaining capacity of the battery through the built-in software in the computer, and display the calculated battery capacity data on the touch screen. At this time, by reading the data on the touch screen, the measurement of the remaining capacity of the test battery is completed.
