Description

Technical Field

[0001] This application relates to the technical field of thermal runaway testing, and particularly to a battery thermal runaway testing tooling. Background Art

[0002] The battery is the core energy source of new energy electric vehicles, and its safety and working reliability directly affect the use safety of new energy electric vehicles. High temperature will significantly reduce the cycle life of the battery, and it is also unsafe during high-rate charging. In order to improve the service life and safety of the battery pack, it is necessary to cool it to keep it working at an appropriate temperature. Among them, the cold plate is a widely used method for cooling the battery at present.

[0003] At present, energy storage customers have higher and higher requirements for the energy density of batteries. Grouping battery cells can significantly improve battery performance and energy density. In the prior art, cooling the battery through a cold plate helps to integrate more battery cells in the battery, thereby increasing the battery cell grouping rate. If the entire battery is tested, the test cost is high and the cycle is long. Once thermal runaway occurs, all the battery cells of the entire battery face scrapping. If the thermal runaway testing tooling of a conventional small module is used for testing, it is impossible to accurately simulate the heat transfer effect between the battery with a higher battery cell grouping rate and the cold plate, resulting in relatively high temperatures when the tested battery cells go out of control.

[0004] In view of this, this application is specifically proposed. Utility Model Content

Detailed Embodiments

[0031] The technical solutions of the present application will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0032] In an embodiment of the present application, a battery thermal runaway test tooling 100 is provided, which is used to simulate the thermal runaway behavior of a battery under test 200. For the specific structure of the battery thermal runaway test tooling 100, please refer to Figures 1 to 4 and Figure 6 , which includes a first flat plate 111, a second flat plate 112, and a cold plate 120. Among them, the second flat plate 112 is arranged below the first flat plate 111 so that the battery under test 200 is clamped between the first flat plate 111 and the second flat plate 112, that is, the battery under test 200 is clamped and fixed along the height direction of the battery under test 200. The first flat plate 111 and the second flat plate 112 are respectively in contact with the top and bottom of the battery under test 200 to press the battery under test 200. That is, the first flat plate 111 and the second flat plate 112 respectively have a top surface and a bottom surface that are oppositely arranged along the height direction. The bottom surface of the first flat plate 111 is attached to the top of the battery under test 200, and the top surface of the second flat plate 112 is attached to the bottom of the battery under test 200, so that the entire battery under test 200 is in a constant extrusion state along its height direction, thereby truly simulating the assembly state of a real battery and ensuring the accuracy of the test; the cold plate 120 is arranged on the top surface of the first flat plate 111 and / or the bottom surface of the second flat plate 112, and can cool the battery under test 200 through the first flat plate 111 and / or the second flat plate 112.

[0033] According to the battery thermal runaway test tooling 100 of the present application, by arranging the cold plate 120 on the top surface of the first flat plate 111 and / or the bottom surface of the second flat plate 112, a thermal runaway test is carried out on the battery under test 200 in a liquid-cooled heat dissipation state, reflecting the real situation of the battery under test 200 in the battery thermal runaway test tooling 100. It not only has a simple design, low cost, and high reuse rate, but also can ensure the rationality, scientificity, and authenticity of the test results.

[0034] Such as Figure 1 and Figure 3As shown, the cold plate 120 includes a cooling channel for accommodating a cooling medium. An inlet pipe 123 and an outlet pipe 124 are provided on the cold plate 120. The inlet pipe 123 and the outlet pipe 124 are respectively communicated with the cooling channel. The cooling medium supply device supplies the cooling medium into the cooling channel through the inlet pipe 123. The cooling medium cools the battery under test 200 through the first flat plate 111 and / or the second flat plate 112. The cooling medium that absorbs the heat of the battery under test 200 flows back to the cooling medium supply device through the outlet pipe 124, so that the cooling medium supply device can cool the cooling medium with increased temperature, thereby realizing the recycling of the cooling medium.

[0035] For the specific structure of the cold plate 120, please refer to Figure 1 and Figure 3 , which includes an upper layer plate 121 and a lower layer plate 122 arranged below the upper layer plate 121. Among them, a cooling channel is formed between the upper layer plate 121 and the lower layer plate 122. The inlet pipe 123 and the outlet pipe 124 are respectively installed on the upper layer plate 121 and communicated with the cooling channel.

[0036] Exemplarily, the upper layer plate 121 and the lower layer plate 122 are fixedly connected by brazing, which is simple to operate and firmly connected. Among them, both the upper layer plate 121 and the lower layer plate 122 are made of 3-series aluminum alloy. A brazing layer is provided between the upper layer plate 121 and the lower layer plate 122. The brazing layer is made of 4-series aluminum alloy. The brazing layer belongs to a solder with a relatively low melting point, and its melting point is lower than that of the upper layer plate 121 and the lower layer plate 122. After heating, the upper layer plate 121 and the lower layer plate 122 do not melt, and the brazing layer melts and fills the gap between the upper layer plate 121 and the lower layer plate 122, thereby sealing the upper layer plate 121 and the lower layer plate 122 to form a cooling channel. Of course, the brazing layer can also be other brazing materials commonly used in the prior art, such as silver brazing material, copper brazing material and nickel brazing material. The upper layer plate 121 and the lower layer plate 122 can also be other weldable metal materials, such as 1-series aluminum alloy, as long as the upper layer plate 121 and the lower layer plate 122 can be firmly connected together.

[0037] As an embodiment not shown, the cold plate 120 is provided on the top surface of the first flat plate 111. Among them, the lower layer plate 122 is attached to the top surface of the first flat plate 111, so that the cold plate 120 can cool the battery under test 200 through the first flat plate 111. Preferably, the first flat plate 111 and the battery under test 200 are bonded by a thermally conductive structural adhesive, which not only conducts the heat generated by the battery under test 200 to the cold plate 120, greatly improving the heat dissipation efficiency and meeting the high-efficiency heat dissipation requirements of the battery under test 200, but also can tightly connect the first flat plate 111 and the battery under test 200 through the thermally conductive structural adhesive to realize the clamping and fixing of the battery under test 200.

[0038] As Figures 1 to 4As shown in the figure, a cold plate 120 is provided on the bottom surface of the second flat plate 112. Among them, the upper layer plate 121 is attached to the bottom surface of the second flat plate 112, so that the cold plate 120 can cool the battery under test 200 through the second flat plate 112. Preferably, the second flat plate 112 and the battery under test 200 are bonded by a thermally conductive structural adhesive, which not only conducts the heat generated by the battery under test 200 to the cold plate 120, greatly improving the heat dissipation efficiency and meeting the high-efficiency heat dissipation requirements of the battery under test 200, but also can tightly connect the second flat plate 112 and the battery under test 200 through the thermally conductive structural adhesive to realize the clamping and fixing of the battery under test 200.

[0039] As Figures 1 to 4 shown, the battery thermal runaway test tooling 100 further includes end plates 113. The end plates 113 are vertically arranged and have an upper end and a lower end arranged opposite to each other in the height direction. The upper and lower ends of the end plates 113 are respectively connected to the first flat plate 111 and the second flat plate 112. The two end plates 113 are arranged on both sides of the battery under test 200 along the first direction D1, so that the battery under test 200 is clamped between the two end plates 113, that is, the battery under test 200 is clamped and fixed along the first direction D1. The two end plates 113 are respectively in contact with both sides of the battery under test 200, pressing the battery under test 200 tightly, so that the entire battery under test 200 is in a constant extrusion state along the first direction D1, thus truly simulating the assembly state of a real battery and further ensuring the accuracy of the test.

[0040] As Figure 1 and Figure 3 shown, the first flat plate 111 and the second flat plate 112 are arranged at intervals along the height direction of the battery under test 200, the two end plates 113 are arranged at intervals along the first direction D1, and the first flat plate 111, the second flat plate 112 and the two end plates 113 are connected in sequence to construct a frame 110 for accommodating the battery under test 200.

[0041] As Figure 1 , Figure 3 and Figure 6 shown, second connecting holes 1111 and 1132 for the second fastener 170 to pass through are respectively formed on the adjacent first flat plate 111 and end plate 113, so that the first flat plate 111 and the end plate 113 are fixedly connected by the second fastener 170, ensuring the firmness of the frame 110, so that the entire battery under test 200 is in a constant extrusion state.

[0042] As Figure 1 , Figure 3 and Figure 4As shown, the battery thermal runaway test tooling 100 further includes an adjusting member 140 for adjusting the distance between two end plates 113. The adjusting member 140 includes a bolt 141 and a nut 142. One end of the bolt 141 passes through the two end plates 113 in the first direction D1 and is screwed with the nut 142. By adjusting the relative position of the nut 142 and the bolt 141, the two end plates 113 are controlled to clamp the battery under test 200 along the first direction D1.

[0043] As Figure 1 , Figure 3 and Figure 4 shown, the battery under test 200 includes battery cells 210. A plurality of battery cells 210 are arranged at intervals along the first direction D1. According to the number and arrangement of the battery cells 210 of the battery under test 200, the relative position of the nut 142 and the bolt 141 is adjusted to adjust the distance between the two end plates 113 along the first direction D1, so that the frame 110 can accommodate different numbers of battery cells 210. The design is simple and the application scenarios are diverse.

[0044] As Figures 1 to 5 shown, the battery thermal runaway test tooling 100 further includes a limiting member 130. The two limiting members 130 are arranged at both ends of the battery under test 200 along the second direction D2 perpendicular to the first direction D1, and are respectively pressed against both ends of the battery under test 200 along the second direction D2, so that the battery under test 200 is clamped between the two limiting members 130, that is, the battery under test 200 is clamped and fixed along the second direction D2. The two limiting members 130 are respectively abutted against both ends of the battery under test 200 to press the battery under test 200, so that the entire battery under test 200 is in a constant extrusion state along the second direction D2, thus truly simulating the assembly state of a real battery and having higher test accuracy.

[0045] As Figure 1 shown, the first direction D1 is substantially perpendicular to the height direction of the battery under test 200. The first direction D1 can be substantially parallel to the length direction of the battery under test 200. Of course, the first direction D1 can also be substantially parallel to the width direction of the battery under test 200. For the convenience of description, in this embodiment, the first direction D1 is substantially parallel to the width direction of the battery under test 200, and the second direction D2 is substantially parallel to the length direction of the battery under test 200.

[0046] As Figures 1 to 4 shown, the limiting member 130 is used to connect two adjacent battery cells 210. The two limiting members 130 press each battery cell 210 along the second direction D2, so that a plurality of battery cells 210 arranged at intervals along the first direction D1 are closely attached, thereby ensuring that the adjacent battery cells 210 are in a pressed state.

[0047] As Figure 2 , Figure 4 andFigure 5 As shown, the limiting member 130 includes limiting teeth 131 that abut against the battery cell 210. The plurality of limiting teeth 131 are arranged at intervals along the first direction D1, so that each limiting tooth 131 abuts against the corresponding battery cell 210. The assembly is simple, the installation is convenient, and the limiting effect is good, so that the battery under test 200 is completely consistent with the extrusion state and pressure of the real battery in the real use environment, and the conclusion obtained from the test can better reflect the real situation.

[0048] As Figure 2 、 Figure 4 and Figure 5 As shown, electrode cover plates 220 are respectively arranged at both ends of the battery cell 210 along the second direction D2. The limiting member 130 is provided with limiting grooves 132. The plurality of limiting grooves 132 are arranged at intervals along the first direction D1, so that the electrode cover plates 220 are inserted into the corresponding limiting grooves 132, thereby clamping and fixing the battery cell 210.

[0049] As Figure 2 、 Figure 4 and Figure 5 As shown, a U-shaped limiting groove 132 is formed between two adjacent limiting teeth 131. The electrode cover plate 220 is inserted into the limiting groove 132 through the open end of the limiting groove 132. The distance between the two side walls of the limiting groove 132 is equivalent to the dimension of the electrode cover plate 220 along the first direction D1, so that the limiting member 130 can better clamp the battery cell 210, and the limiting teeth 131 abut against one end of two adjacent battery cells 210 along the second direction D2. The dimension of the limiting teeth 131 along the first direction D1 is equivalent to the distance between two adjacent electrode cover plates 220, so that the limiting teeth 131 are clamped between two adjacent electrode cover plates 220.

[0050] As Figure 2 、 Figures 4 to 6 As shown, both ends of the limiting member 130 extend outward and bend along the first direction D1 to form connecting ears 133, that is, both ends of the limiting member 130 along the width direction of the battery under test 200 extend outward and bend to form connecting ears 133. First connecting holes 1331 and 1131 for the first fastener 160 to pass through are respectively formed in the adjacent connecting ears 133 and the end plate 113, so that the connecting ears 133 and the end plate 113 are fixedly connected by the first fastener 160, thereby the limiting member 130 is firmly connected to the two end plates 113, so that the two end plates 113 can better clamp the entire battery under test 200, and the adjustment method is flexible and variable.

[0051] As Figure 1 and Figure 3As shown, the battery 200 to be tested includes a plurality of battery cells 210 arranged at intervals in the first direction D1. The battery thermal runaway test tooling 100 further includes a heat insulation pad 150, which is arranged between at least a pair of two adjacent battery cells 210 in the first direction D1. When performing a thermal runaway test on the battery 200 to be tested in a liquid cooling and heat dissipation state, it can reflect the real situation of the battery 200 to be tested within the battery thermal runaway test tooling 100. And the heat insulation pad 150 is arranged between two adjacent battery cells 210. According to the test results of the battery thermal runaway test tooling 100, the heat insulation performance of the heat insulation pad 150 can be quickly determined, with a short test cycle and high reliability.

[0052] As an embodiment not shown, the battery thermal runaway test tooling 100 further includes a temperature sensor for detecting the temperature of the battery 200 to be tested. Among them, the temperature sensor is arranged on the battery cell 210 and / or the explosion-proof valve of the battery 200 to be tested. Specifically, the temperature sensor is arranged at the top of the battery cell 210, the bottom of the battery cell 210, and / or at least one side of the battery cell 210 in the first direction D1, for detecting the temperature of different surfaces of the battery cell 210. The more the number of temperature sensors, the more accurate the temperature detection result.
