Description

Technical Field

[0001] This utility model belongs to the technical field of battery module safety testing equipment, and in particular relates to a mobile battery water ingress safety testing device for battery cell modules. Background Technology

[0002] The safety of lithium batteries and battery packs is currently a primary concern for consumers in the energy storage market. During the design, development, certification, and testing of lithium batteries and battery packs, a series of safety performance tests are required, including tests for overcharging, short circuits, and thermal runaway—all factors that can lead to fire and explosion. Currently, as the number of series and parallel connections in energy storage system designs increases and the energy levels rise, the risk of smoke, fire, or explosion from a battery pack is extremely high. To mitigate the hazards of fire and explosion, laboratories typically use ventilation systems to remove smoke during testing, followed by rapid water extinguishing. For rapid fire extinguishing, compared to the complex lifting structures used in existing technologies, this invention proposes a solution that quickly immerses the battery pack in water, which helps improve safety during testing.

[0027] In one embodiment of this utility model, such as Figures 1-3 As shown, a mobile battery water ingress safety testing device for battery cell modules is provided, including a mobile support device 10, a split carrier plate device 20, and an immersion device 30. The split carrier plate device 20 is movably mounted on the mobile support device 10, and the bottom of the mobile support device 10 is slidably connected to the bottom of the immersion device 30. The split carrier plate device 20 is located above the immersion device 30, and the bottom of the immersion device 30 is provided with casters.

[0028] The mobile battery water ingress safety testing device for battery modules of this utility model is assembled from a mobile support device 10, a split-plate device 20, and an immersion device 30. The split-plate device 20 is horizontally positioned and can be flipped down to open, allowing the product to be tested to fall. During assembly, the split-plate device 20 is movably mounted on the mobile support device 10, allowing it to be rotated and moved to both sides. Then, the bottom of the mobile support device 10 is slidably connected to the immersion device 30. This sliding connection brings the distance between the mobile support device 10 and the immersion device 30 closer, ensuring that the split-plate device 20 is precisely positioned above the immersion device 30. When testing a product, the split-plate device 20 can be opened to allow the product to quickly fall into the immersion device 30. Through the above structural design, the safety issues of the tested product can be quickly resolved.

[0029] In another embodiment of this utility model, such as Figures 1-3As shown, the split-plate device 20 includes a first rotating device 21, a second rotating device 22, and two support plates 23. One end of the first rotating device 21 and the second rotating device 22 are horizontally rotatably connected to the movable support device 10, enabling the first rotating device 21 and the second rotating device 22 to rotate and open to both sides. One edge of the two support plates 23 is fixedly connected to the rotating ends of the first rotating device 21 and the second rotating device 22, respectively, and the two support plates 23 are arranged opposite to each other. The rotation of the first rotating device 21 and the second rotating device 22 controls the two support plates 23. The first rotating device 21 and the second rotating device 22 fix the two support plates 23 to form a plane for product placement. When a problem is detected, the first rotating device 21 and the second rotating device 22 rotate the two support plates 23 downwards, causing the product to fall into the immersion device 30.

[0030] In another embodiment of this utility model, such as Figures 1-3 As shown, both the first rotating device 21 and the second rotating device 22 include a control device and a rotating shaft. The control device is movably mounted on the movable support device 10. One end of the rotating shaft is fixedly connected to the rotating end of the control device. The sides of the two rotating shafts are fixedly connected to the two support plates 23 respectively. The control device controls the rotating shaft to rotate, thereby driving the support plates 23 to rotate.

[0031] In another embodiment of this utility model, such as Figures 1-3 As shown, the movable support device 10 includes a movable base 11, a first lifting rod 12, a second lifting rod 13, and several support rods 14. The movable base 11 is slidably connected to the bottom of the immersion device 30. The first lifting rod 12 and the second lifting rod 13 are both fixedly installed on the movable base 11. Each support rod 14 is spaced between the first lifting rod 12 and the second lifting rod 13, and both ends of the support rod 14 are fixedly connected to the first lifting rod 12 and the second lifting rod 13, respectively. The first rotating device 21 and the second rotating device 22 are respectively installed on the first lifting rod 12 and the second lifting rod 13. The distance between the product and the immersion device 30 is changed by the first lifting device and the second lifting device to control the splashing of water after falling in.

[0032] In another embodiment of this utility model, such as Figures 1-3 As shown, a rotating device is provided on both the first lifting rod 12 and the second lifting rod 13. One end of the first rotating device 21 and the second rotating device 22 are fixedly connected to the two rotating devices respectively. The rotating devices reduce the friction force when the first rotating device 21 and the second rotating device 22 rotate.

[0033] In another embodiment of this utility model, such as Figures 1-3As shown, the top of the mobile base 11 is provided with several sliders, which are slidably connected to the bottom of the immersion device 30. The sliders play a certain guiding role, guiding the mobile base 11 and the immersion device 30 to slide and connect along a relatively fixed trajectory.

[0034] In another embodiment of this utility model, such as Figure 3 As shown, the bottom of the immersion device 30 is provided with several sliding grooves, each of which is slidably connected to a sliding bar, thereby restricting the assembly of the positioning sliding bar.

[0035] In another embodiment of this utility model, such as Figure 3 As shown, the immersion device 30 has a clearance space 31 at the bottom, and the movable base 11 is located in the clearance space 31, which effectively utilizes the space at the bottom of the immersion device 30 and avoids wasting space.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
