Description

Technical Field

[0001] This utility model relates to the field of battery pack testing technology, specifically to an explosion-proof chiller for testing new energy battery packs. Background Technology

[0002] Against the backdrop of the booming development of the new energy vehicle industry, the performance and safety of the new energy battery pack, as a core power component, are directly related to the reliability of the entire vehicle operation. Testing of the new energy battery pack is a key link to ensure its quality. By simulating working environments under different operating conditions, the electrical performance, thermal management capabilities, and safety of the battery pack are comprehensively evaluated.

[0003] Currently, traditional testing methods for new energy battery packs mainly focus on the basic performance of the battery pack, typically monitoring parameters such as temperature, voltage, and current in a relatively stable environment. Testing equipment often emphasizes single-function implementation, such as using a conventional chiller to regulate the temperature of the battery pack to examine its operating status within different temperature ranges. However, this testing method often overlooks the complex operating conditions that battery packs may face in actual use, such as the bumps and impacts of vehicle driving, as well as sudden temperature and humidity changes in extreme environments. This leads to a certain deviation between the test results and actual application scenarios.

[0004] While existing explosion-proof chillers for testing new energy battery packs can achieve precise temperature control and meet basic temperature testing requirements, their functionality is relatively limited. Their main limitation lies in adjusting and testing only temperature parameters, failing to comprehensively simulate the mechanical vibrations, impacts, and other mechanical environments that battery packs may encounter during actual operation, as well as extreme climatic environments such as alternating high and low temperatures and humid heat. As the reliability requirements for battery packs under complex operating conditions continue to increase in new energy vehicles, existing equipment, lacking the ability to collaboratively test multiple environmental factors, struggles to comprehensively assess the safety and stability of battery packs in extreme environments, and thus cannot provide sufficient technical basis for optimized battery pack design. Utility Model Content

[0005] The purpose of this utility model is to provide an explosion-proof chiller for testing new energy battery packs, so as to solve the technical problem that although the explosion-proof chiller for testing new energy battery packs can achieve precise control of battery pack temperature and meet basic temperature testing requirements, its function is relatively simple.

[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0007] An explosion-proof chiller for testing new energy battery packs includes an explosion-proof chiller body; a first cylinder is fixedly connected to the inner side wall of the bottom end of the explosion-proof chiller body; a test plate is fixedly connected to the top end of the first cylinder; a battery body is provided at the top end of the test plate; a connection socket is fixedly connected to the side end of the battery body; a connection plug is provided at the side end of the connection socket; and a test unit is provided at the bottom end of the test plate.

[0008] As a further embodiment of this utility model: the test unit includes a rotary cylinder; the rotary cylinder is fixedly connected to the bottom end of the test plate; an impact groove is provided inside the test plate; an impact ball is rotatably connected to the rotary cylinder, and the impact ball is located at the bottom end of the battery body.

[0009] As a further embodiment of this utility model: an electric push rod is fixedly connected to the inner wall of the explosion-proof chiller body; an electric clamp is fixedly connected to the side end of the electric push rod, and a connecting plug is located on the inner wall of the electric clamp.

[0010] As a further embodiment of this utility model: a second cylinder is fixedly connected to the inner wall of the explosion-proof chiller body; a push plate is fixedly connected to the side end of the second cylinder; a test block is fixedly connected to the side end of the push plate, and the test block is located on the side end near the battery body.

[0011] The beneficial effects of this invention are as follows: The battery is placed on a test plate. After the explosion-proof chiller is turned off, the test plate is raised and then suddenly lowered using a cylinder, causing the battery to fall onto the test plate after being suspended in mid-air, creating a bumpy effect. This tests the battery's anti-bump effect. The test can be repeated. After the battery is on the test plate, a rotating impact ball passes through an impact groove and impacts the battery. A rotating cylinder causes the impact ball to rotate and impact the bottom of the battery, generating vibration. This tests the battery's vibration resistance and effectively simulates the mechanical stresses such as bumps and impacts that the battery may encounter during actual use. The design, in conjunction with the temperature control function of the explosion-proof chiller, enables comprehensive performance testing of the battery under the coupled conditions of temperature changes and mechanical shock. This design overcomes the shortcomings of existing equipment that can only perform temperature testing alone, and can accurately simulate the real working state of the battery in extreme environments. This allows for a comprehensive evaluation of the battery's safety, stability, and structural reliability under the combined effects of temperature and mechanical stress, providing test data that is closer to actual application scenarios for the optimized design of the battery. This significantly improves the practicality and guiding significance of the test results, and helps improve the performance and safety of the battery under complex working conditions.

[0020] During operation, the staff places the battery body 2 on the test plate 4, turns off the explosion-proof chiller body 1, raises the test plate 4 through the first cylinder 3 and then suddenly lowers it, causing the battery body 2 to fall onto the test plate 4 after being suspended in mid-air, creating a bumpy effect, thereby testing the anti-bump effect of the battery body 2. The test can be repeated.

[0021] The test unit includes a rotary cylinder 6; the rotary cylinder 6 is fixed to the bottom end of the test plate 4; the test plate 4 has an impact groove 5 inside; an impact ball 7 is rotatably connected to the rotary cylinder 6 and is located at the bottom end of the battery body 2.

[0022] After the battery body 2 is placed on the test plate 4, the impact ball 7 rotates and impacts the battery body 2 through the impact groove 5. The rotating cylinder 6 causes the impact ball 7 to rotate and impact the bottom of the battery body 2, generating vibration. This can be used to test the vibration test effect of the battery body 2. Together with the first cylinder 3 and the test plate 4, it can meet the testing needs of the battery body 2 in different environments. It can effectively simulate the mechanical stress environment such as bumps and impacts that the battery body 2 may encounter in actual use. It works in conjunction with the temperature control function of the explosion-proof chiller 1 to achieve comprehensive performance testing of the battery body 2 under the coupled working conditions of temperature change and mechanical impact. This design makes up for the shortcomings of existing equipment that can only perform temperature testing. It can accurately simulate the real working state of the battery body 2 in extreme environments, thereby comprehensively evaluating the safety, stability and structural reliability of the battery body 2 under the combined action of temperature stress and mechanical stress. It provides test data that is closer to the actual application scenario for the optimized design of the battery body 2, significantly improving the practicality and guiding significance of the test results, and helping to improve the performance and safety of the battery body 2 under complex working conditions.

[0023] An electric push rod 11 is fixedly connected to the inner wall of the explosion-proof chiller body 1; an electric clamp 13 is fixedly connected to the side end of the electric push rod 11, and a connecting plug 14 is provided on the inner wall of the electric clamp 13.

[0024] After the battery body 2 is placed on the test plate 4, the test plate 4 is clamped and moved towards the battery body 2 by the electric push rod 11. The connecting plug 14 is inserted into the inside of the connecting socket 12 by the electric clamp 13, so that the connecting socket 12 and the connecting plug 14 are connected. The battery body 2 can be tested in the test state of power supply. The connecting plug 14 is connected by a soft wire. The soft wire will not affect the vibration test of the battery body 2.

[0026] The push plate 9 can clamp and limit both ends of the battery body 2 by the second cylinder 8. After the bump test, the test block 10 can be used by the second cylinder 8 to hit the side of the battery body 2. The impact resistance of the battery body 2 can be tested by the irregular shape of the test block 10 hitting the battery body 2. The test can be repeated.

[0027] The working principle of this utility model is as follows: During operation, the operator places the battery body 2 on the test plate 4. After turning off the explosion-proof chiller 1, the test plate 4 is raised and then suddenly lowered by the first cylinder 3, causing the battery body 2 to fall onto the test plate 4, creating a bumpy effect. This tests the anti-bump effect of the battery body 2, and the test can be repeated. After the battery body 2 is on the test plate 4, the impact ball 7 rotates and impacts the battery body 2 through the impact groove 5. The rotating cylinder 6 causes the impact ball 7 to rotate and impact the bottom of the battery body 2, generating vibration. This tests the vibration effect of the battery body 2. Together with the first cylinder 3 and the test plate 4, it can meet the testing needs of the battery body 2 in different environments. It can effectively simulate the mechanical stress environment such as bumps and impacts that the battery body 2 may encounter during actual use. It works in conjunction with the temperature control function of the explosion-proof chiller 1 to achieve comprehensive performance testing of the battery body 2 under the coupled conditions of temperature change and mechanical impact. This design makes up for the deficiency of existing equipment that can only perform temperature testing, and can accurately simulate the real working conditions of the battery body 2 in extreme environments. The test plate 4 is used to comprehensively evaluate the safety, stability, and structural reliability of battery body 2 under the combined effects of temperature and mechanical stress. This provides test data that is closer to actual application scenarios for the optimized design of battery body 2, significantly improving the practicality and guiding significance of the test results, and helping to improve the performance and safety of battery body 2 under complex working conditions. After battery body 2 is placed on test plate 4, test plate 4 is clamped and moved towards battery body 2 by electric push rod 11. Connector plug 14 is inserted into connector socket 12 by electric clamp plate 13, so that connector socket 12 and connector plug 14 are connected. This allows testing of battery body 2 in the power supply test state. Connector plug 14 is connected by a soft wire, which will not affect the vibration test of battery body 2. Push plate 9 can clamp and limit both ends of battery body 2 by cylinder 8. After the vibration test, test block 10 can be used by cylinder 8 to impact the side of battery body 2. The impact of irregular shape of test block 10 on battery body 2 is used to test the impact resistance of battery body 2. This test can be repeated.
