Description

Technical Field

[0001] This utility model relates to the field of lead-acid battery testing technology, and more specifically, to a battery electrolyte retention testing device. Background Technology

[0002] In existing technologies, during the use of lead-acid batteries, charging affects the electrolyte level, primarily due to chemical reactions and internal temperature changes. The charging process of a lead-acid battery involves more than just storing electrical energy; it also involves electrolysis of water in the electrolyte. During charging, oxygen is released from the positive electrode, while hydrogen is released from the negative electrode, forming bubbles. If the battery casing is poorly sealed or the battery cover is not adequately designed to handle gas release, these gases may carry away acid from the electrolyte, leading to acid leakage, affecting battery life, or causing environmental pollution.

[0003] During vehicle operation, the lead-acid battery in the vehicle will be in a charging state for a long time. In addition, the battery may tilt due to bumps, uphill and downhill driving, etc., causing the electrolyte in the battery to leak from the vent at the top.

[0004] like Figure 1 As shown, the current method and apparatus use a 45° testing fixture. The battery is tilted 45° from a vertical position onto the fixture within 1 second and held for 3 seconds. Then, within 1 second, it is returned to a vertical position, and the electrolyte is visually inspected for any splashing. This battery testing method is too simplistic and cannot cover the operating conditions of batteries in vehicles, making it difficult to measure whether lead-acid batteries will leak during actual use.

[0057] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0058] Example 1

[0059] To address the aforementioned problems, this invention provides a battery electrolyte retention testing device, such as... Figures 2-6 As shown, it includes:

[0060] Tabletop frame 1;

[0061] The testing platform is used to house the batteries;

[0062] A driver, used to rotate the platform to simulate vehicle vibrations;

[0063] Controller 4 is used to control the driver to perform actions at a predetermined frequency;

[0064] Limiting components are used to control the rotation angle of the detection platform;

[0065] The testing platform is rotatably connected to the frame 1; the drive body is rotatably connected to the frame 1; the drive end of the drive is rotatably connected to the testing platform; the controller 4 is electrically connected to the drive; and the limit assembly is movably mounted on the frame 1.

[0066] When the drive end of the driver extends, the detection platform abuts against one end of the limit component; when the drive end of the driver retracts, the detection platform abuts against the other end of the limit component.

[0067] In practical applications, the frame 1 supports the entire battery testing equipment, and the testing platform holds the battery. After the battery is placed, a driver moves the testing platform back and forth, causing the battery on the platform to shake, simulating the vibrations, accelerations, decelerations, inclines, and lateral tilts experienced by a vehicle during actual operation. The controller 4 controls the driver's movement according to a pre-set program, enabling the driver to vibrate at a predetermined frequency. A limit component adjusts the driver's rotation angle; by adjusting the position of the limit component, the rotation angle of the testing platform can be controlled, thereby adjusting the battery's rotation angle and movement distance. In summary, the driver in this application can drive the testing platform to rotate at a predetermined frequency, simulating the vibrations generated by a vehicle during actual operation. This simulation accurately reproduces the battery's operating state in a vehicle vibration environment, verifying its electrolyte retention capacity. This testing method overcomes the shortcomings of traditional static testing, making the test results more realistic and reliable. The controller 4 is electrically connected to the driver and can automatically control the rotation of the testing platform according to a predetermined frequency and program. This automated design avoids manual intervention, which not only reduces the difficulty of operation but also improves testing efficiency and accuracy.

[0068] In one embodiment, the detection platform includes: a support column 21 and a positioning plate 22; one end of the support column 21 is fixedly connected to the middle of the positioning plate 22; the support column 21 and the positioning plate 22 are arranged perpendicular to each other; the middle of the support column 21 is rotatably connected to the platform frame 1; and the driving end of the driver is rotatably connected to the side of the support column 21 away from the positioning plate 22.

[0069] In practical applications, the middle part of the support column 21 is rotatably connected to the platform frame 1, ensuring smooth rotation of the testing platform, effectively reducing shaking and offset during operation, and improving the overall structural stability of the equipment. The support column 21 is fixedly connected to the positioning plate 22, and the two are set perpendicular to each other, so that the testing platform has good anti-overturning ability when subjected to the rotational force applied by the driver. The driving end of the driver is rotatably connected to the far end of the support column 21, so that the power of the driver can be transmitted to the testing platform more effectively. The connection between the support column 21 and the positioning plate 22 provides strong support when the testing platform carries the battery, which can meet the load requirements of batteries with large weight or different specifications.

[0070] In one embodiment, the testing platform further includes: a fixing strip 23 for pressing the battery, two limiting screws 24, and two limiting nuts 25; the two limiting screws 24 are respectively disposed on both sides of the positioning plate 22, and the arrangement direction of the two limiting screws 24 is consistent with the swing direction of the testing platform; the two limiting screws 24 are both perpendicular to the positioning plate 22; through slots are respectively opened at both ends of the fixing strip 23; the two limiting screws 24 pass through the two through slots respectively; the fixing strip 23 is slidably disposed on the limiting screws 24; the two limiting nuts 25 are respectively threadedly connected to the two limiting screws 24 one-to-one, for limiting the fixing strip 23 in the vertical direction.

[0071] In practical applications, the design of the fixing strip 23 can apply pressure to the battery during the test, firmly pressing it onto the test platform. This effectively prevents the battery from sliding, tilting, or shifting when the drive platform rotates. This is especially important in dynamic tests simulating vehicle vibration, ensuring the consistency of test conditions and preventing changes in battery position from affecting the accuracy of test results. The combination of the limiting screw 24 and the limiting nut 25 allows the fixing strip 23 to slide and adjust along the direction of the limiting screw 24, thus adapting to batteries of different sizes and specifications. The fixing strip 23 is provided with a through groove, allowing it to pass smoothly through the limiting screw 24 and slide for adjustment. Installation or adjustment can be completed without disassembling the limiting screw 24, greatly improving the convenience and efficiency of operation.

[0072] In one embodiment, the limiting component includes: a first limiting baffle and a second limiting baffle;

[0073] The bottom of the first limiting baffle and the bottom of the second limiting baffle are respectively movably connected to the platform frame 1;

[0074] The first and second limiting baffles are symmetrically arranged on both sides of the support column 21;

[0075] When the drive end of the driver extends, the other end of the support column 21 abuts against the first limiting baffle; when the drive end of the driver retracts, the other end of the support column 21 abuts against the second limiting baffle.

[0076] In practical applications, by designing a first limit baffle and a second limit baffle, the device can bidirectionally limit the swing of the detection platform when the driver drives the platform to rotate.

[0077] This design effectively controls the swing angle of the testing platform, preventing excessive swing from affecting the accuracy of the experiment and further improving the safety and stability of the equipment operation. Two limit baffles cooperate with the extension and retraction actions of the drive end, allowing the testing platform to contact the corresponding baffles under different operating conditions, achieving precise control of the swing range. This controllability of the swing range can meet the needs of different testing conditions, such as adjusting the swing angle according to different vehicle vibration modes, thereby improving the applicability of the equipment.

[0078] In one embodiment, the first limiting baffle includes: a first base plate 511, a first side plate 512, and at least one first limiting bolt 515; the second limiting baffle includes: a second base plate 521, a second side plate 522, and at least one second limiting bolt.

[0079] The bottom end of the first side plate 512 is fixedly connected to one end of the first base plate 511; the first base plate 511 is provided with a first sliding groove 514; the first limiting bolt 515 passes through the first sliding groove 514 and is fixedly connected to the platform frame 1.

[0080] The bottom end of the second side plate 522 is fixedly connected to one end of the second base plate 521; a second sliding groove is provided on the second base plate 521; the second limiting bolt passes through the second sliding groove and is fixedly connected to the platform frame 1.

[0081] In practical applications, the distance between the first side plate 512 and the second side plate 522 is adjusted by sliding on the limiting bolt via a groove. When the first limiting bolt 515 is loosened, the friction between the first limiting bolt 515 and the first base plate 511 decreases, allowing the first base plate 511 to move smoothly to adjust the position of the first side plate 512. Once the position of the first side plate 512 is adjusted, tightening the first limiting bolt 515 secures the first side plate 512 using the friction between the first limiting bolt 515 and the first base plate 511. The operating principle of the second limiting bolt and the second base plate 521 is the same as that of the first base plate 511.

[0082] In one embodiment, the first limiting baffle includes two first limiting bolts 515; the second limiting baffle includes two second limiting bolts; the arrangement direction of the two first limiting bolts 515 is the same as the movement direction of the cylinder 33, and the distance between the two first limiting bolts 515 is less than or equal to half the length of the first slide groove 514; the arrangement direction of the two second limiting bolts is the same as the movement direction of the cylinder 33, and the distance between the two second limiting bolts is less than or equal to half the length of the second slide groove.

[0083] This design ensures that the baffle's limiting capability can effectively cope with the forces generated when the cylinder 33 drives the platform, especially the impact force along the direction of cylinder 33's movement. The limiting bolt provides a more uniform force distribution, improving the stability and durability of the limiting structure. The fit between the bolt and the slide groove allows users to flexibly adjust the specific limiting range of the limiting baffle by adjusting the position of the bolt in the slide groove, in order to adapt to the platform's swing angle requirements under different testing conditions.

[0084] In one embodiment, both the first side plate 512 and the second side plate 522 are inclined, and the included angle between the first side plate 512 and the second side plate 522 is... .

[0085] In practical applications, in order to simulate the driving environment of a vehicle, the tilt angle of the vehicle is usually not more than 15°. Therefore, limiting the included angle between the two side panels to 30° can better match the usage environment of the battery.

[0086] In one embodiment, the limiting component further includes: a first buffer block 513 and a second buffer block 523; the first buffer block 513 is disposed on the surface of the first side plate 512 facing the second side plate 522; the second buffer block 523 is disposed on the surface of the second side plate 522 facing the first side plate 512.

[0087] In practical applications, when the detection platform swings and contacts the limit baffle, the buffer block can absorb some of the impact force, reducing the force directly transmitted to the limit baffle and other components, thereby reducing stress concentration in the limit assembly and the platform frame 1. This improves the equipment's impact resistance in high-frequency vibration or large-amplitude swing environments, protecting critical components from damage. When the detection platform swings to its extreme position, the elastic material of the buffer block can reduce the direct collision between the detection platform and the limit baffle, reducing noise generated by the collision. In this application, the buffer block can be made of rubber or soft sponge pad material.

[0088] In one embodiment, the actuator includes: a first solenoid valve 31, a second solenoid valve 32, and a cylinder 33;

[0089] The first solenoid valve 31 and the second solenoid valve 32 are both electrically connected to the controller 4; the outer shell of the cylinder 33 is rotatably connected to the platform frame 1, and the drive end of the cylinder 33 is rotatably connected to the side of the support column 21 away from the positioning plate 22.

[0090] The output end of the first solenoid valve 31 is connected to the first vent of the cylinder 33 through an air supply pipe; the output end of the second solenoid valve 32 is connected to the second vent of the cylinder 33 through an air supply pipe.

[0091] When the first solenoid valve 31 is turned on and the second solenoid valve 32 is turned off, the driving end of the cylinder 33 extends outward; when the first solenoid valve 31 is turned off and the second solenoid valve 32 is turned on, the driving end of the cylinder 33 retracts inward.

[0092] With both the first solenoid valve 31 and the second solenoid valve 32 closed, the support column 21 is in a vertical position and the cylinder 33 is in a horizontal position.

[0093] In practical applications, cylinder 33 is used as the core component of the actuator, enabling rapid extension and retraction. Compared with traditional mechanical transmission, cylinder 33 has a faster response speed, meeting the requirements of high-frequency vibration simulation testing. The linkage control between the solenoid valve and cylinder 33 allows for rapid start and stop, improving the efficiency of the testing process. The first solenoid valve 31 and the second solenoid valve 32 respectively control the two vents of cylinder 33, allowing for precise adjustment of the extension and retraction of cylinder 33, ensuring that the swing amplitude and frequency of the testing platform meet the testing requirements.

[0094] In one embodiment, such as Figure 6 As shown, the controller 4 includes: a microcontroller U1, a first transistor Q1, and a second transistor Q2;

[0095] The first output terminal of the microcontroller U1 is electrically connected to the base of the first transistor Q1;

[0096] The second output terminal of the microcontroller U1 is electrically connected to the base of the second transistor Q2;

[0097] The positive terminals of the first solenoid valve 31 and the second solenoid valve 32 are both electrically connected to the power supply voltage terminal.

[0098] The negative terminal of the first solenoid valve 31 is electrically connected to the collector of the first transistor.

[0099] The negative terminal of the second solenoid valve 32 is electrically connected to the collector of the second transistor.

[0100] The emitters of both the first and second transistors are grounded.

[0101] In practical applications, the microcontroller uses an STC89C52RC chip. Two pins of the microcontroller are connected to two transistors via current-limiting resistors. When the pins output a high level, the transistors conduct, their base and emitter are connected, and the solenoid valve is open, allowing the gas tank 34 to transfer high-pressure gas to the cylinder 33. When the pins output a low level, the transistors are cut off, their base and emitter are cut off, and the solenoid valve is closed, disconnecting the connection between the gas tank 34 and the cylinder 33. Therefore, by controlling the opening and closing of the two solenoid valves, the cylinder 33 can be extended or retracted accordingly. The program programmed into the microcontroller controls the two pins to output high and low levels respectively, controlling the cylinder to extend outwards or retract inwards. Using the microcontroller to execute a predetermined program to output high or low levels on predetermined pins is known to those skilled in the art; therefore, the process of programming and executing the program will not be elaborated upon in this application.

[0102] Example 2

[0103] In this embodiment, the present invention also provides a battery testing method, specifically including:

[0104] 1. After resting at 25℃±2℃ for 24 hours, apply a voltage of 16.0V±0.1V and a current limit of I. max =5I 20 Charging for 24 hours, of which I 20 I represents the current when the battery discharges at a 20-hour rate. max =5I 20 This indicates that the maximum charging current is less than five times I. 20 ;

[0105] 2. After charging is complete, place the container at an ambient temperature of 50℃±2℃ for 24 hours.

[0106] 3. Fix the battery on the electrolyte retention test device for 2 hours each along the long side and the short side of the battery;

[0107] 4. Test angle: 15°; tilt time: 0.2 seconds from one side to the other; battery movement: 50mm in total; test frequency: 12±2 cycles per minute;

[0108] 5. During the test, the battery remained in a charging state with a voltage of 14.8V ± 0.05V and a maximum current of 10I. n , where I n This is the rated charging current during charging;

[0109] 6. Requirements after the test: There should be no electrolyte leakage or seepage. Check with absorbent paper.

[0110] Using the above method, parameters such as voltage, current, time, angle, tilt time, movement distance, and frequency are clearly defined and precise, ensuring that the testing process complies with strict experimental specifications and enhancing the reliability and comparability of the test results. Tilting and shaking the battery at 15° during the test simulates the movement, vibration, and tilting conditions that the battery might experience in actual use, thereby verifying the battery's sealing performance and shock resistance. In particular, checking for electrolyte leakage or seepage risks allows for a comprehensive assessment of the battery's reliability and safety under vehicle driving conditions. After the test, using methods such as blotting paper to check for electrolyte leakage or seepage is not only rigorous but also provides reliable assurance for the battery's safety in actual use, offering more accurate judgment results compared to traditional visual inspection methods.

[0111] In many practical applications (such as vehicle batteries and UPS backup batteries), batteries are often kept charged under vibration or movement. Testing the battery's charging performance during shaking provides a better way to verify its adaptability under these conditions. During charging, an internal electrochemical reaction occurs, generating gas and pressure. This internal pressure can lead to electrolyte leakage or seepage. By maintaining the battery in a charging state during shaking tests, the sealing performance of the battery during charging can be more realistically tested, and the risk of leakage under high-pressure vibration environments can be identified.

[0112] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0113] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
