Description

Technical Field

[0001] This utility model relates to the field of energy storage battery testing technology, specifically an energy storage battery testing device. Background Technology

[0002] There are many testing items for energy storage batteries, including performance testing, safety testing, environmental adaptability testing, and life testing. Among them, life testing simulates the actual use process by subjecting the energy storage battery to multiple complete charge-discharge cycles.

[0003] Battery testers are mainly used to detect current, voltage, capacity, internal resistance, temperature, and battery cycle life, and provide curves. Battery testers are currently the most commonly used equipment for battery life testing. The principle of testing battery life is to calculate the battery life by measuring the ion content on the surface of the electrode plates.

[0004] When testing energy storage batteries, it is necessary to simulate both high and low temperature conditions in the test environment. However, it was found in the test that simply placing the energy storage battery in the simulated environment during the test made it difficult for the energy storage battery to fully contact the test environment, thus reducing the authenticity of the test data.

[0005] Therefore, a testing device for energy storage batteries is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A battery testing device of this utility model includes a testing box, the side wall of which is connected to a pipe; multiple heat engines are fixedly connected inside the testing box; a pair of sliding grooves are opened inside the testing box; a sliding rod is slidably fitted inside the sliding grooves; a cover plate is fixedly connected to the top of the sliding rod; a detector is installed on the top of the cover plate; a support frame is fixedly connected to the middle of the cover plate; a pair of square rods are hinged to the bottom of the cover plate; the square rods and the support frame are fixed by pins; a pressure relief assembly is provided on the side wall of the testing box; by using the square rods to fix the battery, the installation of the battery can be accelerated, thereby reducing the preparation time before testing; using the support frame can elevate the battery, thereby increasing the contact between the battery and the ambient temperature, making the testing environment of the battery closer to the real environment, and allowing the battery to be in full contact with the ambient temperature, thus increasing the authenticity of the test data.

[0008] Preferably, multiple round rods are fixedly connected to the top of the testing box; the round rods and the cover plate are in a sliding fit; a rubber pad is fixedly connected to the outer wall of the round rod; by adding round rods, guidance can be added when the cover plate and the testing box are combined, and the rubber pad will fill the gap between the round rod and the cover plate, thereby increasing the friction between the round rod and the cover plate, increasing the resistance when the cover plate moves, and thus increasing the alignment of the cover plate and the testing box.

[0009] Preferably, a pair of spring telescopic rods are fixedly connected to the inner wall of the slide groove; a slider is fixedly connected to the end of the spring telescopic rod; the end of the slider is arc-shaped; by adding the slider, the slider can be supported after the slider moves, so that the slider does not need to be completely pulled out, which can reduce the alignment during the installation of the slider. Because the spring telescopic rod will continuously apply a pushing force to the slider, the weight of the slider will not push the slider away when the slider supports the slider, thereby reducing the movement of the slider.

[0010] Preferably, a buffer pad is fixed to the bottom of the support frame; multiple buffer pads are provided on the support frame; by adding buffer pads, the impact between the support frame and the test box during movement can be reduced, thereby protecting the energy storage battery and reducing damage caused by impact. At the same time, the buffer pads provide support between the support frame and the test box, keeping the support frame in a suspended state, thereby increasing the contact between the energy storage battery and the surrounding temperature.

[0011] Preferably, a first sealing gasket is fixedly connected to the bottom of the cover plate; a plurality of second sealing gaskets are fixedly connected to the top of the test box; the first sealing gasket and the second sealing gasket are in sliding fit; by adding the first sealing gasket and the second sealing gasket, the second sealing gasket can form a wall after entering the interior of the first sealing gasket to block the external airflow, thereby reducing the loss of airflow inside the test box and thus reducing the impact on the energy storage battery test.

[0012] Preferably, the pressure relief assembly includes a vent valve; the vent valve and the test chamber are connected; the vent valve is located in the middle of the test chamber; the vent valve can increase the balance of air pressure inside the test chamber, thereby reducing potential test hazards.

[0013] Preferably, the round rod is rectangular; by making the round rod rectangular, the cover plate and the detection box can be quickly aligned when they are joined, thereby reducing misalignment gaps and increasing sealing performance.

[0014] Preferably, the buffer pad is arc-shaped; by making the buffer pad arc-shaped, the impact force can be reduced after the support frame enters the testing box and reaches the bottom. When the buffer pad is buffering, the end will gradually flatten out, thereby quickly absorbing the impact force and accelerating the reduction of the impact force.

[0015] The advantages of this utility model are:

[0016] 1. The energy storage battery testing device of this utility model can speed up the installation of the energy storage battery by using a square rod to fix the energy storage battery, thereby reducing the preparation time before testing. The support frame can be used to support the energy storage battery, thereby increasing the contact between the energy storage battery and the ambient temperature, making the testing environment of the energy storage battery close to the real environment, and making the energy storage battery fully exposed to the ambient temperature, thereby increasing the authenticity of the test data.

[0017] 2. The energy storage battery testing device of this utility model can be guided by adding a round rod when the cover plate and the testing box are combined. At the same time, the rubber pad fills the gap between the round rod and the cover plate, increasing the friction between the round rod and the cover plate. This increases the resistance when the cover plate moves, thereby increasing the alignment of the cover plate and the testing box. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0026] Specific implementation examples are given below.

[0027] like Figures 1 to 5 As shown in the embodiment of this utility model, an energy storage battery testing device includes a testing box 1, with a pipe 11 connected to the side wall of the testing box 1; multiple heat engines 12 are fixedly connected inside the testing box 1; a pair of sliding grooves 17 are opened inside the testing box 1; a sliding rod 13 is slidably fitted inside the sliding grooves 17; a cover plate 14 is fixedly connected to the top of the sliding rod 13; a detector 18 is installed on the top of the cover plate 14; a support frame 15 is fixedly connected to the middle of the cover plate 14; a square rod 16 is hinged to the bottom of the cover plate 14; the square rod 16 and the support frame 15 are fixed by a pin. The test chamber 1 is equipped with a pressure relief assembly 19 on its side wall. During operation, the cover plate 14 is first removed from the test chamber 1. As the cover plate 14 moves, the sliding rod 13 gradually moves away from the interior of the test chamber 1. After the sliding rod 13 is completely removed from the test chamber 1, the cover plate 14 is placed on the ground, at which point the support frame 15 provides support. Then, the square rod 16 is rotated to open the support frame 15. The energy storage battery is then placed inside the support frame 15. After the energy storage battery is placed inside the support frame 15, the square rod 16 is rotated back to its initial position, at which point the bottom of the square rod 16 enters the support frame. Inside 15, insert the pin to merge the square rod 16, then lift the cover plate 14 and move it above the test box 1. At this time, lower the cover plate 14 so that the slide rod 13 enters the slide groove 17. When the cover plate 14 contacts the test box 1, it means that the energy storage battery is in the middle position of the test box 1. Then start the pipe 11 to transmit cold air to lower the internal temperature of the test box 1 to simulate the low temperature test environment of the energy storage battery. When it is necessary to test the energy storage battery under high temperature conditions, the gas inside the test box 1 needs to be discharged through the pressure relief component 19 first, and then use the heat engine. 12. Simply raise the internal temperature of the test chamber 1. After the energy storage battery has been placed for a period of time, remove it from the test chamber 1. Then, connect the test clamp of the detector 18 to the terminal of the energy storage battery for testing. Using the square rod 16 to fix the energy storage battery can speed up the installation of the energy storage battery and reduce the preparation time before testing. Using the support frame 15 can support the energy storage battery and increase the contact between the energy storage battery and the ambient temperature, so that the test environment of the energy storage battery is close to the real environment, and the energy storage battery is in full contact with the ambient temperature, thereby increasing the authenticity of the test data.

[0028] like Figures 1 to 4 As shown, multiple round rods 2 are fixedly connected to the top of the testing box 1; the round rods 2 and the cover plate 14 are in sliding fit; a rubber pad 21 is fixedly connected to the outer wall of the round rods 2; during operation, when the cover plate 14 and the testing box 1 are combined, the round rods 2 will enter the interior of the cover plate 14, and at the same time, they will increase the guidance when the cover plate 14 moves down, thereby reducing the misalignment between the cover plate 14 and the testing box 1. This reduces the impact of external airflow on the test data by entering the interior of the testing box 1 through the gaps. At the same time, the rubber pad 21 increases the friction between the round rods 2 and the cover plate 14, increasing the resistance when the cover plate 14 and the round rods 2 come into contact. By adding round rods 2, guidance can be increased when the cover plate 14 and the testing box 1 are combined, and the rubber pad 21 will fill the gap between the round rods 2 and the cover plate 14, increasing the friction between the round rods 2 and the cover plate 14, increasing the resistance when the cover plate 14 moves, and thus increasing the alignment of the cover plate 14 and the testing box 1.

[0029] like Figure 5 As shown, a pair of spring telescopic rods 3 are fixedly connected to the inner wall of the slide groove 17; a slider 31 is fixedly connected to the end of each spring telescopic rod 3; the end of the slider 31 is arc-shaped; during operation, when the slide rod 13 enters the slide groove 17, it will contact the slider 31 and squeeze it, causing the slider 31 to enter the slide groove 17. When the slide rod 13 is fully inside the slide groove 17, the slider 31 will be pushed by the spring telescopic rod 3 and thus stick tightly to the surface of the slide rod 13. When the slide rod 13 is gradually pulled out of the slide groove 17, the slider 31 will gradually be pulled out of the slide groove 17. When the slide rod 13 leaves the surface of the slider 31, the two sliders 31 will merge to form a support to lift the slide rod 13. At this time, the square rod 16 can be operated to open the support frame 15 without fully pulling out the slide rod 13. By adding sliders 31, the slide rod 13 can be supported after it moves, so it is not necessary to fully pull out the slide rod 13. This reduces the need for alignment when installing the slide rod 13. Because the spring telescopic rod 3 will continuously apply a pushing force to the slider 31, the weight of the slide rod 13 will not push the slider 31 away when the slider 31 supports the slide rod 13, thus reducing the movement of the slide rod 13.

[0030] like Figure 4 As shown, a buffer pad 4 is fixedly attached to the bottom of the support frame 15; multiple buffer pads 4 are provided on the support frame 15; during operation, when the support frame 15 carrying the energy storage battery enters the testing box 1, the weight of the battery will cause the downward speed to increase. When the slide bar 13 enters the deepest part, the support frame 15 will experience a sudden drop, moving downward a certain distance before rebounding. At this time, the buffer pad 4 will contact the bottom of the testing box 1 to absorb the impact force. By adding the buffer pad 4, the impact between the support frame 15 and the testing box 1 during movement can be reduced, thereby protecting the energy storage battery and reducing damage caused by the impact. At the same time, the buffer pad 4 provides support between the support frame 15 and the testing box 1, keeping the support frame 15 in a suspended state, thereby increasing the contact between the energy storage battery and the surrounding temperature.

[0031] like Figure 1 As shown, a first sealing gasket 5 is fixedly connected to the bottom of the cover plate 14; multiple second sealing gaskets 51 are fixedly connected to the top of the test box 1; the first sealing gasket 5 and the second sealing gasket 51 are in sliding fit; during operation, when the cover plate 14 and the test box 1 are combined, the second sealing gasket 51 will enter the interior of the first sealing gasket 5, thereby reducing the airflow from the connection point when the test box 1 and the cover plate 14 are combined and blocking the external airflow; by adding the first sealing gasket 5 and the second sealing gasket 51, the second sealing gasket 51 can form a wall after entering the interior of the first sealing gasket 5 to block the external airflow, thereby reducing the loss of airflow inside the test box 1 and reducing the impact on the energy storage battery test.

[0032] like Figure 1 As shown, the pressure relief assembly 19 includes a vent valve 6; the vent valve 6 and the test chamber 1 are connected; the vent valve 6 is located in the middle of the test chamber 1; during operation, when the energy storage battery needs to be removed after testing, the vent valve 6 is used to release the air pressure inside the test chamber 1 before opening the cover 14 to remove the energy storage battery; the vent valve 6 can balance the air pressure inside the test chamber 1, thereby reducing potential testing hazards.

[0033] like Figure 1 As shown, the round rod 2 is rectangular; by making the round rod 2 rectangular, the cover plate 14 and the detection box 1 can be quickly aligned when they are joined, thereby reducing misalignment gaps and increasing sealing.

[0034] like Figure 4 As shown, the buffer pad 4 is arc-shaped. By making the buffer pad 4 arc-shaped, the impact force can be reduced after the support frame 15 enters the detection box 1 and reaches the bottom. When the buffer pad 4 is buffering, the end will gradually flatten out to quickly absorb the impact force and accelerate the reduction of the impact force.

[0035] Working principle: First, remove the cover plate 14 from the inside of the detection box 1. As the cover plate 14 moves, the sliding rod 13 will gradually leave the inside of the detection box 1. After the sliding rod 13 is completely pulled out of the detection box 1, place the cover plate 14 on the ground. At this time, the support frame 15 will provide support. Then, rotate the square rod 16 to open the support frame 15. Then, put the energy storage battery into the support frame 15. After the energy storage battery is put into the support frame 15, rotate the square rod 16 to the initial position. At this time, the bottom of the square rod 16 will enter the support frame 15. Then, insert the pin to close the square rod 16. Then, lift the cover plate 14 and move it to the top of the detection box 1. At this time, move the cover plate 14 down so that the sliding rod 13 enters the sliding groove 17. When the cover plate 14 and the detection box 1 are closed, the sliding rod 13 enters the sliding groove 17. When the test chamber 1 is in contact, it indicates that the energy storage battery is in the middle position of the test chamber 1. Then, the pipe 11 is activated to transmit cold air, which lowers the internal temperature of the test chamber 1 to simulate the low-temperature test environment of the energy storage battery. When it is necessary to test the energy storage battery under high temperature conditions, the gas inside the test chamber 1 needs to be discharged through the pressure relief component 19 first, and then the heat pump 12 is used to raise the internal temperature of the test chamber 1. After the energy storage battery has been placed for a period of time, it is removed from the test chamber 1. At this time, the test clamp of the detector 18 is connected to the terminal of the energy storage battery for testing. When the cover plate 14 and the test chamber 1 are closed, the round rod 2 will enter the cover plate 14 and provide guidance when the cover plate 14 moves down, thereby reducing the misalignment between the cover plate 14 and the test chamber 1, thus ensuring smooth testing. To reduce the impact of external airflow entering the test chamber 1 through gaps on test data, the rubber pad 21 increases friction between the round rod 2 and the cover plate 14, increasing resistance when they contact. When the sliding rod 13 enters the slide groove 17, it contacts the slider 31, squeezing it and causing the slider 31 to enter the groove 17. Once the sliding rod 13 is fully inside the groove 17, the slider 31 is pushed by the spring extension rod 3, pressing it tightly against the surface of the sliding rod 13. As the sliding rod 13 gradually withdraws from the groove 17, the slider 31 gradually pulls out. When the sliding rod 13 leaves the surface of the slider 31, the two sliders 31 merge to form a support, lifting the sliding rod 13. At this point, the operation can proceed without fully withdrawing the sliding rod 13. Open the support frame 15 using the square rod 16; when the support frame 15, carrying the energy storage battery, enters the test box 1, the weight of the battery will cause the downward speed to increase. When the sliding rod 13 enters the deepest part, the support frame 15 will jolt, moving downward a certain distance before rebounding. At this time, the buffer pad 4 will contact the bottom of the test box 1 to absorb the impact force; when the cover plate 14 and the test box 1 are closed, the second sealing gasket 51 will enter the interior of the first sealing gasket 5, thereby reducing the airflow from the connection point when the test box 1 and the cover plate 14 are closed, and blocking the external airflow; when the energy storage battery needs to be removed after testing, the air pressure inside the test box 1 should be released first using the vent valve 6, and then the cover plate 14 should be opened to remove the energy storage battery.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
