Description

Technical Field

[0002] With the rapid development of electric vehicles, power batteries are widely used. As one of the high-voltage components of electric vehicles, the electromagnetic compatibility performance test of power batteries is a must-check item for all car manufacturers.

[0003] Most of the electromagnetic compatibility performance tests of power batteries need to be conducted in an anechoic chamber, where absorbing materials are laid to absorb the electromagnetic waves generated by the tested samples. If the power battery has thermal runaway, the open flame generated by the power battery will ignite the absorbing materials, and thick smoke will fill the entire anechoic chamber. Since the space inside the anechoic chamber is limited and filled with high voltage electricity, it is difficult to extinguish the fire of the power battery in the anechoic chamber.

DETAILED DESCRIPTION

[0025] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0026] Referring to Fig. 1, a battery electromagnetic compatibility performance test system provided in an embodiment of the present application includes an anechoic chamber 30, a test antenna 31, a test device, and an emergency device. The wall of the anechoic chamber 30 is provided with an absorbing material 32, and the test antenna 31, the test device, and the emergency device are arranged in the anechoic chamber 30.

[0027] 2 , the emergency device includes an emergency housing 10, and the emergency housing 10 includes a first panel 12. Optionally, the emergency housing 10 is a cube, and the size of the emergency housing 10 can be set according to actual needs, for example, the height of the emergency housing 10 is 90 cm.

[0028] Optionally, the first panel 12 includes a first conductor and a first substrate, and the first conductor covers the upper surface of the first substrate. The first conductor can be a copper plate, a galvanized steel plate, etc., and the first substrate can be a wooden board, etc., but is not limited thereto. Alternatively, the first panel 12 includes a first conductor having a certain thickness.

[0029] Further, referring to Fig. 1, the first conductor is provided with a grounding element 14. In this way, the use safety of the emergency device can be improved.

[0030] 1 and 2 , the test device includes a test housing 80. The test housing 80 includes a second panel 82, and the first panel 12 is conductively connected to the second panel 82.

[0031] Optionally, the second panel 82 includes a second conductor and a second substrate, and the second conductor covers the upper surface of the second substrate. The second conductor can be a copper plate, a galvanized steel plate, etc., and the second substrate can be a wooden board, etc., but is not limited thereto. Alternatively, the second panel 82 includes a second conductor having a certain thickness.

[0032] It can be understood that the conductive connection between the first panel 12 and the second panel 82 refers to the contact and matching between the conductor of the first panel 12 and the conductor of the second panel 82 .

[0033] Referring to FIG1 , when the battery electromagnetic compatibility performance is tested, the battery 90 is placed on the first panel 12 of the emergency device, and auxiliary equipment such as the LISN (Line Impedance Stabilization Network) is placed on the second panel 82. If the battery 90 thermally runs away, the emergency device quickly cools the battery 90, blocks open flames, and filters dense smoke.

[0034] In one embodiment, referring to FIG. 2 , the first panel 12 includes a fixed plate 121 and a movable plate 122 for carrying the battery 90. The fixed plate 121 is provided with a mounting opening, and the movable plate 122 is provided at the mounting opening and can be electrically connected to the fixed plate 121. It is understood that, in non-emergency situations, the conductor of the fixed plate 121 is in contact with the conductor of the movable plate 122.

[0035] Optionally, the installation opening is located in the middle of the fixing plate 121. Of course, in other embodiments, the installation opening may also be located at other positions of the fixing plate 121, and is not limited thereto.

[0036] It should be noted that the shapes of the fixed plate 121, the movable plate 122 and the mounting opening can be set according to actual needs and are not specifically limited here. For example, in this embodiment, the fixed plate 121, the movable plate 122 and the mounting opening are all square. Of course, in other embodiments, the fixed plate 121, the movable plate 122 and the mounting opening can also be circular, elliptical, diamond-shaped, etc., without limitation thereto.

[0037] Furthermore, the emergency housing 10 is provided with a containing cavity, which is a closed type. The emergency device also includes a water pool and a driving mechanism. The water pool is provided in the containing cavity, and the water pool is located below the movable plate 122. The driving mechanism is connected to the movable plate 122, and the driving mechanism is used to drive the movable plate 122 to move so that the battery 90 falls into the water pool.

[0038] It should be noted that the pool should have fire and explosion-proof functions. Optionally, the pool is made of stainless steel, but is not limited thereto.

[0039] It should be noted that the driving mechanism should have a waterproof function to avoid damage to the driving mechanism and extend the service life of the driving mechanism.

[0040] Referring to FIG. 1 and FIG. 2 , when the battery electromagnetic compatibility performance is tested, the battery 90 is placed on the movable plate 122. If the battery 90 is in thermal runaway, the driving mechanism drives the movable plate 122 to move, so that the battery 90 on the movable plate 122 falls into the pool, and the water in the pool extinguishes the battery in thermal runaway, so as to quickly cool down and seal the open flame, thereby avoiding fire and ensuring safety in use. In addition, damage to the anechoic chamber 30 can be avoided.

[0041] It should be noted that when the battery electromagnetic compatibility performance test is performed, the high-voltage line interface of the battery 90 is well plugged into the low-voltage line interface, but the buckle is not locked to ensure that the driving mechanism will not break the line when driving the movable plate 122 to move, or pull the auxiliary equipment such as the LISN on the second panel 82 into the pool.

[0042] In one embodiment, the driving mechanism is a lifting mechanism, and the driving mechanism is used to drive the movable plate 122 to move toward or away from the bottom of the pool. Optionally, the driving mechanism is a Z-shaped or X-shaped electric push rod. During the battery electromagnetic compatibility performance test, if the battery 90 thermally runs away, the driving mechanism drives the movable plate 122 to move toward the bottom of the pool to bring the battery 90 into the pool, and the water in the pool quickly cools the battery 90, closes the open flame, etc. After the emergency treatment is completed, the driving mechanism drives the movable plate 122 to move in the direction away from the bottom of the pool, which can also be understood as moving in the direction close to the installation port, until the movable plate 122 is located at the installation port and is conductively connected to the fixed plate 121.

[0043] Of course, in other embodiments, the driving mechanism may also be other structures. Specifically, one side of the movable plate 122 is rotatably connected to the fixed plate 121, and the fixed plate 121 is provided with an electric plug. When the battery electromagnetic compatibility performance test is performed, at least part of the electric plug is located below the movable plate 122 to support the movable plate 122 so that the movable plate 122 is in a horizontal state. If the battery 90 thermally runs away, the electric plug retracts, and after the movable plate 122 loses support, the other side of the movable plate 122 connected to the fixed plate 121 rotates toward the accommodating cavity, and the battery 90 falls into the pool under the action of its own gravity.

[0044] In one embodiment, referring to FIG. 5 , the emergency device further includes a control unit 20. The control unit 20 includes an ascending switch 21 and a descending switch 22, and the ascending switch 21 and the descending switch 22 are connected in parallel. The ascending switch 21 and the descending switch 22 are both electrically connected to the driving mechanism, and the ascending switch 21 is used to control the driving mechanism to drive the movable plate 122 to ascend, and the descending switch 22 is used to control the driving mechanism to drive the movable plate 122 to descend. Optionally, the ascending switch 21 and the descending switch 22 are press switches or rotatable gear switches.

[0045] When the battery 90 is in thermal runaway, the descending switch 22 is closed, and the driving mechanism drives the movable plate 122 to move toward the bottom of the pool. When the movable plate 122 descends to a preset height, the battery 90 enters the pool and is submerged by the water in the pool, and the driving mechanism stops.

[0046] After the emergency treatment is completed, the rising switch 21 is closed, and the driving mechanism drives the movable plate 122 to move toward the installation opening. When the movable plate 122 rises to a preset height, the movable plate 122 is located at the installation opening, and the driving mechanism stops.

[0047] Further, referring to FIG5 , the control unit 20 further includes an emergency switch 23. The emergency switch 23 is connected in series with the ascending switch 21, and the emergency switch 23 is connected in series with the descending switch 22. It is understandable that only when the emergency switch 23 is closed, the ascending switch 21 and the descending switch 22 can control the action of the driving mechanism. In this way, by providing the emergency switch 23, the ascending switch 21 and the descending switch 22 can be prevented from being misoperated.

[0048] In one embodiment, the pool is provided with a water inlet hole, the water inlet hole is provided with a water inlet pipe for communicating with the water inlet pipe of the anechoic chamber 30, and the water inlet pipe is provided with a water inlet valve. Optionally, the water inlet valve is an electric water valve. When the water inlet valve is opened, water flows into the pool through the water inlet pipe to fill the pool with water. After the water filling is completed, the water inlet valve is closed.

[0049] Furthermore, the emergency device also includes a liquid level sensor, which is arranged in the pool. Specifically, the liquid level sensor is arranged at the upper part of the pool to detect whether the pool is full of water. The liquid level sensor is electrically connected to the control unit 20 and the water inlet valve, and the control unit 20 is used to control the water inlet valve to open or close according to the liquid level information collected by the liquid level sensor. When in use, the water inlet valve is opened, and water flows into the pool through the water inlet pipe. In this process, the liquid level sensor detects the water level in the pool in real time. When the water in the pool is full, the control unit 20 controls the water inlet valve to close and stops injecting water into the pool.

[0050] In one embodiment, referring to FIG5 , the control unit 20 further includes an automatic water injection switch 24 and a forced water injection switch 25. The automatic water injection switch 24 and the forced water injection switch 25 are electrically connected to the water inlet valve, respectively. The automatic water injection switch 24 is used to control the water inlet valve to open or close according to the liquid level information collected by the liquid level sensor, and the forced water injection switch 25 is used to control the water inlet valve to remain in a normally open state.

[0051] The automatic water filling switch 24 is closed, and the water inlet valve is opened to fill water into the pool. At the same time, the liquid level sensor detects the water level in the pool in real time. When the water in the pool is full, the control unit 20 controls the water inlet valve to close and stop filling water into the pool.

[0052] The forced water filling switch 25 is closed, and the water inlet valve remains in a normally open state. When the water in the pool is full, the water inlet valve also remains in an open state, and water continues to be poured into the pool. It is understandable that after the forced water filling switch 25 is closed, water continues to be poured into the pool, regardless of whether the pool is full of water.

[0053] Further, referring to FIG5 , the automatic water injection switch 24 is connected in parallel with the forced water injection switch 25, and the automatic water injection switch 24 is connected in series with the emergency switch 23, and the forced water injection switch 25 is connected in series with the emergency switch 23. It can be understood that the automatic water injection switch 24 and the forced water injection switch 25 can control the water inlet valve only when the emergency switch 23 is closed. In this way, the automatic water injection switch 24 and the forced water injection switch 25 can be prevented from being misoperated.

[0054] In one embodiment, the emergency device further comprises an overflow tank body, which is arranged in the accommodating cavity. The water pool is arranged in the overflow tank body, and the overflow tank body is used to collect water overflowing from the top of the water pool. The overflow tank body is provided with a drain port, and the drain port is provided with a drain pipe for communicating with the drain pipe of the anechoic chamber 30. During the water filling process, if the water inlet valve is not closed after the water in the water pool is full, water will continue to be filled into the water pool, so that the water in the water pool will overflow into the overflow tank body, and the water in the overflow tank body will be discharged through the drain pipe.

[0055] In one embodiment, the emergency device further includes a fireproof cloth. The fireproof cloth is arranged on the emergency housing 10, and is used to cover the installation opening when the movable plate 122 moves and exposes the installation opening. When the battery electromagnetic compatibility performance is tested, the movable plate 122 is arranged at the installation opening to cover the installation opening. If the battery 90 thermally runs away, the driving mechanism drives the movable plate 122 to move to expose the installation opening, and the waterproof cloth automatically covers the position of the installation opening, so as to prevent the thick smoke in the accommodating cavity from being discharged into the anechoic chamber 30 through the installation opening.

[0056] Optionally, a linear module is provided on opposite sides of the installation opening. A winding shaft is provided between the two linear modules, the winding shaft is located at one end of the linear module, the fireproof cloth is wound around the winding shaft, and the side of the fireproof cloth away from the winding shaft is connected to the moving part of the linear module. The linear module can pull the fireproof cloth to move in a direction away from the winding shaft so that the fireproof cloth covers the installation opening. The linear module can also drive the fireproof cloth to move in a direction close to the winding shaft so that the installation opening is exposed.

[0057] In one embodiment, the emergency housing 10 is provided with a smoke exhaust port. Optionally, the smoke exhaust port is provided on the side or back of the emergency housing 10. The smoke exhaust port is communicated with the accommodating cavity, and the smoke exhaust port is provided with a smoke exhaust pipe for communicating with the smoke exhaust pipe of the anechoic chamber 30. The thick smoke generated by the thermal runaway of the battery 90 can be discharged to the outside of the anechoic chamber 30 through the smoke exhaust pipe.

[0058] In one embodiment, referring to FIG. 2 and FIG. 3 , the fixed plate 121 is provided with a first plug-in slot 1211. The movable plate 122 is provided with a first plug-in connector 1221. The first plug-in connector 1221 is arranged in the first plug-in slot 1211 on the side facing away from the movable plate 122 and is conductively connected to the slot wall of the first plug-in slot 1211. In this way, the concave-convex plug-in method is adopted, so that the fixed plate 121 and the movable plate 122 can be better conductively connected, while ensuring the integrity of the conductor of the fixed plate 121 and the conductor of the movable plate 122, thereby reducing the resistance. In addition, it is also convenient for quick disassembly and assembly.

[0059] Of course, in other embodiments, the movable plate 122 is provided with a first plugging slot 1211. The fixed plate 121 is provided with a first plugging member 1221, and the first plugging member 1221 is disposed in the first plugging slot 1211 on a side away from the fixed plate 121 and is conductively connected to the slot wall of the first plugging slot 1211.

[0060] In this embodiment, the first plug connector 1221 is a metal sheet. The edge of the movable plate 122 is provided with a metal sheet extending outward, and one side of the metal sheet is arranged between the first wooden board and the first conductor and is conductively connected to the first conductor.

[0061] Further, referring to FIG. 3 , the first plug-in slot 1211 has two opposite slot walls provided with a first elastic sheet 1212 and a second elastic sheet 1213. The first plug-in connector 1221 is provided between the first elastic sheet 1212 and the second elastic sheet 1213, one side of the first plug-in connector 1221 contacts the first elastic sheet 1212, and the other side of the first plug-in connector 1221 contacts the second elastic sheet 1213. In this way, the first elastic sheet 1212 and the second elastic sheet 1213 cooperate to clamp the first plug-in connector 1221, ensuring good contact.

[0062] Of course, in other embodiments, one of the slot walls of the first plug-in slot 1211 is provided with a spring sheet, the first plug-in component 1221 is arranged between the spring sheet and the other slot wall of the first plug-in slot 1211, and one side of the first plug-in component 1221 contacts the spring sheet, and the other side of the first plug-in component 1221 contacts the slot wall of the first plug-in slot 1211.

[0064] In one embodiment, referring to Fig. 2, a ferrite 15 is disposed on the side of the emergency housing 10. Thus, by disposing the ferrite 15 on the side of the emergency housing 10 facing the test antenna 31, the reflection of electromagnetic waves by the metal surface can be reduced.

[0065] It should be noted that other absorbing materials 32 may also be used to replace the ferrite 15 .

[0066] In one embodiment, referring to FIG. 2 and FIG. 4 , the second panel 82 is provided with a second plug-in slot 821. The first panel 12 is provided with a second plug-in connector 1214, and the second plug-in connector 1214 is arranged in the second plug-in slot 821 on the side facing away from the first panel 12 and is conductively connected to the slot wall of the second plug-in slot 821. In this way, the concave-convex plug-in method is adopted, so that the first panel 12 and the second panel 82 can be better conductively connected, while ensuring the integrity of the conductor of the first panel 12 and the conductor of the second panel 82, and reducing the resistance. In addition, it is also convenient for quick disassembly and assembly.
