Description

Technical Field

[0001] This invention relates to the field of battery testing platform technology, and specifically to an ultra-high voltage energy storage battery testing platform and method. Background Technology

[0002] In battery safety testing, compression, puncture, and drop tests are crucial standards, especially for ultra-high voltage energy storage batteries, whose safety performance requires focused testing to meet national standards. Most current testing platforms only offer one or two of these tests. For example, Chinese Patent 201910968904.6 discloses a drop testing device comprising: a test fixture and a transmission mechanism, wherein the test fixture is connected to the transmission mechanism; the test fixture is used to fix the battery under test and control the drop angle of the battery under test; and the transmission mechanism is used to control the test fixture to clamp and release the battery under test.

[0003] For the aforementioned existing technologies, performing one or two individual tests on energy storage batteries, such as squeezing, puncturing, and dropping, cannot effectively simulate complex collision and damage environments. If multiple combinations and multiple individual tests are required, transfer between devices is necessary, which is not only unsafe but also inefficient. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose an ultra-high voltage energy storage battery testing platform and method, which solves the technical problem that in the prior art, performing one or two separate tests on energy storage batteries, such as squeezing, puncture, and drop, cannot effectively simulate complex collision and damage environments.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: In a first aspect, the present invention provides an ultra-high voltage energy storage battery testing platform, comprising: The explosion-proof container is designed for dropping objects and has an inlet on one side. The extrusion mechanism includes a shifting drive and a clamping assembly. The shifting drive is installed inside the explosion-proof box. The movable end of the shifting drive is connected to the clamping assembly. The shifting drive drives the clamping assembly to rotate at least in a first direction to adjust the clamping angle and move in a second direction to adjust the clamping position. The clamping assembly has a clamping plate end that can be opened and closed and whose clamping force can be adjusted, for clamping the battery and extruding the battery. A needle-piercing mechanism, mounted on the clamping plate end of the clamping assembly, has a retractable needle-piercing end for piercing the battery. A rolling mechanism, installed on the inner bottom wall of the drop explosion-proof box, has a platform surface with an adjustable tilt angle; and A lifting platform, located on one side of the rolling mechanism, is used to lift the battery.

[0006] In some embodiments, the displacement drive includes a linear displacement drive and a rotary drive. The linear displacement drive is installed on the inner top wall of the drop explosion-proof box and has a movable end that moves along the inlet axis. The rotary drive is installed on the movable end of the linear displacement drive and has a movable end that rotates about a vertical rotation axis. The clamping assembly is installed on the movable end of the rotary drive.

[0007] In some embodiments, the clamping assembly includes a frame, a telescopic drive member, and a clamping plate. The frame is fixedly connected to the movable end of the rotary drive member, and two telescopic drive members are mounted opposite each other on the frame and connected to the clamping plates one by one.

[0008] In some embodiments, the rolling mechanism includes a collision platform, a tilting telescopic assembly, and an arc-shaped guide plate. One end of the tilting telescopic assembly is hinged to the drop explosion-proof box, and the other end is hinged to the bottom of the collision platform. An arc-shaped guide plate is provided on one side of the collision platform, and the other side is hinged to the drop explosion-proof box.

[0009] In some embodiments, the lifting platform includes a base, an arc-shaped baffle, a tilting and telescopic assembly, and a lifting assembly. One side of the arc-shaped baffle is hinged to the base. One end of the tilting and telescopic assembly is hinged to the base, and the other end is hinged to the arc-shaped baffle. The arc-shaped baffle and the arc-shaped guide plate are respectively arranged on both sides of the collision platform, and the side of the collision platform that is hinged to the explosive-proof drop box corresponds to the arc-shaped baffle, serving as a rolling barrier on both sides of the collision platform. The movable end of the lifting assembly is connected to the base, driving the base to move up and down along the height direction of the explosive-proof drop box.

[0010] In some embodiments, the lifting assembly includes slings and winches, two winches are installed on the inner top wall of the drop explosion-proof box, the movable end of one winch is connected to two slings, the winch drives the slings to wind or unwind, and the four slings are respectively connected to the top four corners of the base.

[0011] In some embodiments, the acupuncture mechanism includes an acupuncture telescopic component and a puncture needle. The acupuncture telescopic component is mounted on the clamping plate, and the clamping plate has through holes corresponding to the puncture needles one by one. The puncture needles are inserted into the through holes.

[0012] In some embodiments, the arc-shaped baffle has an arc surface that is concave from the outer periphery to the center of the central arc-shaped baffle to guide the battery to slide down to the center position of the central arc-shaped baffle.

[0013] In some embodiments, an explosion-proof door is installed near the explosion-proof container near the inlet for opening or closing the inlet, and a conveyor belt is also installed on the inlet for transporting batteries.

[0014] Secondly, the present invention also provides a testing method for an ultra-high voltage energy storage battery testing platform as described in any of the above claims, comprising the following steps: Place the battery at the inlet with its outer circumferential surface compressed as needed, and lift the platform to the inlet height; The battery is clamped by a squeezing mechanism and moved to a lifting platform, where it is placed into a drop-out explosion-proof box. First, a squeezing step is performed. The battery is released from the lifting platform, and the position and orientation of the clamping components are adjusted by the displacement drive to clamp and increase the force for squeezing. Then, the needle puncture step is performed simultaneously. The needle puncture mechanism is activated to simulate the simultaneous extrusion and needle puncture, and the lifting platform is lowered to the side of the rolling mechanism at the same time. Then, the drop test is performed. The battery is moved directly above the rolling mechanism, the clamp is released, and the battery falls onto the rolling mechanism. The rolling mechanism is then tilted to perform a drop impact test at a fixed angle. The battery is tilted towards the lifting platform via a rolling mechanism, causing it to roll onto the platform and then be lifted to the height of the inlet. Depending on the needs, the compression, puncture, or drop tests can be repeated to simulate complex, multiple collisions and damage environments. If multiple squeezes are required for a single item, the above-mentioned falling steps can be skipped and repeated. If multiple acupuncture points are required for a single point, repeat the above-mentioned dropping and squeezing steps with increased force. If multiple drops are required for a single item, the squeezing and pricking steps described above can be skipped and repeated.

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0019] To address the technical problem that performing one or two individual tests—compression, puncture, and drop—on energy storage batteries cannot effectively simulate complex collision and damage environments, this invention provides an ultra-high voltage energy storage battery testing platform. This platform, constructed by incorporating compression, puncture, rolling, and lifting mechanisms within an explosion-proof enclosure, allows for repeated compression, puncture, and drop tests. It simulates the complex environmental safety performance under multiple combinations of battery compression, puncture, and drop, and can perform individual tests involving multiple compressions, multiple punctures, or multiple drops.

[0020] It should be noted that the ultra-high voltage energy storage battery testing platform described in this invention is used for, but not limited to, ultra-high voltage energy storage batteries. For ease of explanation, this invention will only use the application of the ultra-high voltage energy storage battery testing platform to ultra-high voltage energy storage batteries as an example. The principle of the ultra-high voltage energy storage battery testing platform applied to other types of equipment is essentially the same as that applied to ultra-high voltage energy storage batteries, and will not be described in detail here.

[0021] Please see Figure 1-5The present invention provides an ultra-high voltage energy storage battery testing platform, which includes a drop explosion-proof box 1, a compression mechanism 2, a needle-punching mechanism 3, a rolling mechanism 4, and a lifting platform 5. The right side of the explosion-proof drop box 1 has an inlet 101. The explosion-proof drop box 1 is an explosion-proof enclosure, serving as external protection for safety testing to prevent battery explosions from damaging external factory buildings and confining potential explosions within the enclosure. The extrusion mechanism 2 includes a shifting drive 21 and a clamping assembly 22. The extrusion mechanism 2 is mainly used for clamping and transferring batteries and for pressurizing batteries. The shifting drive 21 is installed inside the explosion-proof drop box 1, and its movable end is connected to the clamping assembly 22. It drives the clamping assembly 22 to rotate at least along a first direction to adjust the clamping angle and move along a second direction to adjust the clamping position. The first direction is the rotation axis along the Z-axis of the three-dimensional coordinate system XYZ, and the second direction is the X-axis along the inlet 101. The clamping assembly 22 has a clamping plate end that can be opened and closed and whose clamping force can be adjusted. The clamping assembly 22 is used to hold and compress the battery. When the clamping force is low enough not to cause damage to the battery, the battery can be clamped. With the help of the shifting drive 21, the battery position can be transferred. Increasing the clamping force will cause the battery to be compressed for compression testing. The needle-punching mechanism 3 is installed on the clamping plate end of the clamping assembly 22 and has a retractable needle-punching end for puncturing the battery. The needle-punching mechanism 3 can be installed on the clamping assembly 22 to perform needle-punching tests while compressing. The rolling mechanism 4 is installed on the inner bottom wall of the drop explosion-proof box 1 and has an adjustable tilt platform surface as a collision platform for drop testing. The tilt angle of the drop collision plane can be adjusted to simulate different drop collision angles. The lifting platform 5 is set on one side of the rolling mechanism 4 and is used to lift the battery. For dropped batteries, the lifting is used to re-perform compression, needle-punching or drop tests, connecting multiple repeated tests of the battery.

[0022] In one embodiment, please refer to Figure 2 To achieve clamping and moving of the battery, as well as multi-angle clamping and squeezing, the displacement drive 21 includes a linear displacement drive 211 and a rotary drive 212. The linear displacement drive 211 is installed on the inner top wall of the drop explosion-proof box 1 and has a movable end that moves axially along the inlet 101. The rotary drive 212 is installed on the movable end of the linear displacement drive 211 and has a movable end that rotates about a vertical rotation axis. The clamping assembly 22 is installed on the movable end of the rotary drive 212. The linear displacement drive 211 drives the clamping assembly 22 to move linearly, and the rotary drive 212 drives the clamping assembly 22 to rotate and adjust the clamping angle.

[0023] Understandably, in order to clamp different surfaces of the battery at different angles during clamping, the battery is manually positioned so that the surfaces to be clamped are located around the placement position, which can be clamped by the clamping component 22. As long as the surfaces to be clamped are not located at the top or bottom during placement, it is acceptable.

[0024] In this embodiment, the linear displacement drive 211 can be a motor-driven lead screw guide pair for linear drive, while the rotary drive 212 can be a stepper motor to control the rotation angle of the clamping assembly 22 for rotational adjustment. The above-mentioned devices can be used for both the linear displacement drive 211 and the rotary drive 212, but are not the only options; other existing mechanisms that can achieve the same effect are also acceptable.

[0025] In one embodiment, please refer to Figure 2 In order to achieve basic clamping and squeezing effects, the clamping assembly 22 includes a frame 221, a telescopic drive component 222, and a clamping plate 223. The frame 221 is fixedly connected to the movable end of the rotary drive component 212. The two telescopic drive components 222 are mounted opposite each other on the frame 221 and are connected to the clamping plates 223 one by one. By telescopically extending and retracting the telescopic drive components 222, the two clamping plates 223 are controlled to move relative to each other or move away from each other to form clamping or loosening.

[0026] In this embodiment, the telescopic drive component 222 can be a hydraulic telescopic rod with a hydraulically damped adjustable mechanism. It utilizes the viscous resistance generated when a fluid, typically hydraulic oil, flows through a small orifice or valve to dissipate kinetic energy. The movement of the telescopic rod pushes a piston, forcing the oil to flow. The key to adjusting the force lies in adjusting the opening degree of the damping valve or the flow characteristics. It can provide a large damping force and has a wide adjustment range.

[0027] In one embodiment, please refer to Figure 2 To provide multi-angle drop impact protection, the rolling mechanism 4 includes a collision platform 41, an angle telescopic assembly 42, and an arc-shaped guide plate 43. One end of the angle telescopic assembly 42 is hinged to the drop explosion-proof box 1, and the other end is hinged to the bottom of the collision platform 41. An arc-shaped guide plate 43 is provided on one side of the collision platform 41, and the other side is hinged to the drop explosion-proof box 1. By adjusting the extension and retraction of the angle telescopic assembly 42, the collision platform 41 can be rotated to adjust its tilt angle, and the arc-shaped guide plate 43 provides side protection.

[0028] Furthermore, to provide protection on the other side of the collision platform 41 and to facilitate battery lifting, the lifting platform 5 includes a base 51, an arc-shaped baffle 52, a tilting and telescopic assembly 53, and a lifting assembly 54. One side of the arc-shaped baffle 52 is hinged to the base 51, one end of the tilting and telescopic assembly 53 is hinged to the base 51, and the other end is hinged to the arc-shaped baffle 52. The arc-shaped baffle 52 and the arc-shaped guide plate 43 are respectively arranged on both sides of the collision platform 41, forming protection on both sides. The side of 41 that is hinged to the explosion-proof box 1 corresponds to the arc-shaped baffle 52 and is used to block the rolling of the collision platform 41 on both sides. The movable end of the lifting assembly 54 is connected to the base 51, driving the base 51 to rise and fall along the height direction of the explosion-proof box 1. Through the lifting platform 5, the battery can be lifted from the bottom. With the collision platform 41 tilting towards the lifting platform 5 and the arc-shaped baffle 52 rotating downward to a horizontal state, the battery can be caught. Under the lifting, the battery can be lifted.

[0029] Furthermore, to avoid interference from the lifting structure on the battery during its fall, the lifting assembly 54 includes slings 541 and winches 542. Two winches 542 are installed on the inner top wall of the explosion-proof drop box 1. The movable end of one winch 542 is connected to two slings 541. The winches 542 drive the slings 541 to wind or unwind. The four slings 541 are respectively connected to the top four corners of the base 51. By having the slings 541 close to the side wall of the explosion-proof drop box 1, the space occupied is small and it is not easy to cause interference with the battery. Under the winding of the winches 542, the slings 541 can be wound up, thereby lifting the base 51 and the arc-shaped baffle 52.

[0030] Understandably, the winch 542 is equipped with an outer protective shell, and the outer protective shell has corresponding holes for the hoisting cable 541 to pass through. The outer protective shell protects the winch 542 and prevents the battery from exploding and damaging the winch 542.

[0031] In one embodiment, please refer to Figure 2 In order to perform puncture tests on the clamping plate 223, the needle puncture mechanism 3 includes a needle telescopic component 31 and a puncture needle 32. The needle telescopic component 31 is installed on the clamping plate 223. The clamping plate 223 has through holes that correspond one-to-one with the puncture needles 32. The puncture needles 32 are inserted into the through holes to avoid interference between the puncture structure and the compression. Furthermore, the needle puncture mechanism 3 embedded in the clamping plate 223 can form punctures at the compression position.

[0032] In one embodiment, please refer to Figure 1In order to guide the battery, the arc-shaped baffle 52 has an arc surface that is concave from the outer periphery to the inner side, which guides the battery to slide to the center position of the central arc-shaped baffle 52, so that the subsequent clamping assembly 22 can clamp it.

[0033] In one embodiment, please refer to Figure 1 and Figure 2 To facilitate battery transport away from the explosion-proof container 1, an explosion-proof door 102 is installed near the explosion-proof container 1 at the inlet 101 for opening or closing the inlet 101. A conveyor belt 103 is also installed on the inlet 101 for transporting batteries. Batteries are manually placed on the conveyor belt 103 and transported to the inlet 101. At the inlet 101, the clamping assembly 22 clamps the batteries, and the shifting drive 21 moves the batteries. The batteries are then closed through the explosion-proof door 102, allowing for a sealing test and improving safety.

[0034] To better understand this invention, the following is combined with... Figures 1 to 5 The technical solution of the present invention is described in detail as follows: Batteries are manually placed on conveyor belt 103, which transports them into inlet 101. Clamping assembly 22 clamps the batteries. A displacement drive 21 moves the clamping assembly 22 and the batteries into the explosion-proof drop box 1, placing them on the lifting platform 5. The angle is then adjusted to a squeezing angle, and the clamped batteries are moved to a suspended area inside the explosion-proof drop box 1 to increase the clamping force and create compression. Simultaneously, the needle-piercing telescopic assembly 31 pushes the batteries through the piercing mechanism. The needle 32 punctures the battery. After puncture and compression, the clamping component 22 releases the clamp, allowing the battery to fall freely onto the impact platform 41. The reciprocating extension and retraction of the tilting telescopic component 42 causes the impact platform 41 to tilt alternately left and right, causing the battery to roll and simulating the rolling motion after a fall. After the above tests, the battery is rolled onto the horizontal arc-shaped guide plate 43, where the lifting component 54 lifts it back to the height of the inlet 101, allowing for subsequent compression, needle puncture, or drop tests.

[0035] The present invention also provides a testing method for an ultra-high voltage energy storage battery testing platform as described in any of the above embodiments, comprising the following steps: Place the battery on its outer periphery, which needs to be compressed, at inlet 101, and lift platform 5 is lifted to the height of inlet 101; The battery is clamped by the squeezing mechanism 2 and moved onto the lifting platform 5, then into the explosion-proof drop box 1; First, a squeezing step is performed. The battery is released from the lifting platform 5. The position and orientation of the clamping assembly 22 are adjusted by the shifting drive component 21 to clamp and increase the force for squeezing. Then, the needle puncture step is carried out simultaneously. The needle puncture mechanism 3 is activated to simulate the simultaneous extrusion and needle puncture, and the lifting platform 5 is lowered to the side of the rolling mechanism 4 at the same time. Then, the drop test is performed. The battery is moved directly above the rolling mechanism 4, the clamp is released, and the battery falls onto the rolling mechanism 4. The rolling mechanism 4 is adjusted to tilt, and a drop impact test at a fixed angle is performed. The battery is tilted to the side facing the lifting platform 5 by the rolling mechanism 4, so that it rolls onto the lifting platform 5 and is then lifted to the height of the inlet 101. Depending on the needs, the compression, puncture, or drop tests can be repeated to simulate complex, multiple collisions and damage environments. If multiple squeezes are required for a single item, the above-mentioned falling steps can be skipped and repeated. If multiple acupuncture points are required for a single point, repeat the above-mentioned dropping and squeezing steps with increased force. If multiple drops are required for a single item, the squeezing and pricking steps described above can be skipped and repeated.

[0036] The specific embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any other corresponding changes and modifications made in accordance with the technical concept of the present invention should be included within the scope of protection of the claims of the present invention.
