The safety box stores a cooling and flame-retardant substance. A support plate is located on the top surface of the safety box, used to hold the device under test (DUT). The support component is inserted into the side wall of the safety box. One side of the support plate is hinged to the side wall of the safety box, and the other side is fixed by the support component to maintain a horizontal state. The support component is detachably connected to the safety box and the support plate.

[0032] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0033] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0034] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0035] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0036] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0037] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0038] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0039] In the early stages of battery development, it is necessary to repeatedly verify various parameters of the battery to ensure that its performance meets design requirements. However, during the verification process, batteries may catch fire or explode due to various performance and structural issues. This can cause significant damage to on-site equipment, as the charging and discharging equipment used for testing is relatively expensive, and can also result in personal injury.

[0040] To address the aforementioned issues, this embodiment provides a battery testing system that can prevent damage to the charging and discharging equipment 1 and personnel injury during battery thermal runaway, thereby improving the safety of the testing process.

[0041] like Figures 1-5 As shown, the battery testing system of this embodiment includes a charging / discharging device 1, a support member 2, a safety box 3, and a conductive component. The safety box 3 stores a cooling and flame-retardant material. A support plate 31 is located on the top surface of the safety box 3, and the support plate 31 is used to place the test piece 100. The support member 2 is inserted into the side wall of the safety box 3. One side of the support plate 31 is hinged to the side wall of the safety box 3, and the other side of the support plate 31 is fixed by the support member 2 to maintain a horizontal state. The support member 2 is detachably connected to the safety box 3 and the support plate 31. This allows the support member 2 to be pulled out of the safety box 3, causing the other side of the support plate 31 to fall, and the test piece 100 on the support plate 31 to fall into the cooling and flame-retardant material. The conductive component connects the charging / discharging device 1 and the test piece 100, forming a charging / discharging circuit. The conductive component includes a pluggable connector 4.

[0042] In the event of a fire or explosion of the battery under test, simply removing the support 2 will cause the battery to fall into the cooling and flame-retardant material, rapidly cooling it down. This extinguishes the fire or inhibits combustion, thus preventing or delaying thermal runaway, protecting the charging / discharging equipment 1 from damage, and preventing personnel injury, thereby improving the safety of the testing process. Furthermore, the pluggable connector 4 can be quickly disconnected from the charging / discharging equipment 1, further enhancing its safety.

[0043] Optionally, the support plate 31 is horizontally set in the supported state, and in the unsupported state, the support plate 31 is almost vertically set, with the hinged side at the top and the side requiring support from the support member 2 at the bottom, that is, the top opening of the safety box 3 is fully open, and the test piece 100 falls into the cooling flame retardant material.

[0044] like Figure 4 As shown, optionally, in this embodiment, the safety box 3 has a first sidewall 32 and a second sidewall 33 disposed opposite to each other. The support member 2 is partially inserted into the through hole of the first sidewall 32 and partially inserted into the through hole of the second sidewall 33. That is, the support member 2 passes through the through hole of the first sidewall 32 and the through hole of the second sidewall 33 in sequence, so that the support member 2 is stably fixed on the safety box 3, and the support member 2 between the first sidewall 32 and the second sidewall 33 is used to support the upper support plate 31.

[0045] Optionally, in some embodiments, a support groove is provided on the support plate 31, and the support member 2 is partially inserted into the support groove. That is, the support member 2 is partially inserted into the through hole in the side wall of the safety box 3 and partially inserted into the support groove to support the support plate 31.

[0046] Optionally, in some embodiments, the support groove is formed on the end face of the support plate 31 facing the cooling flame-retardant material, and one end of the support member 2 abuts in the support groove. To ensure stability, a limiting groove can be formed on the support member 2, so that the lower edge of the through hole in the side wall of the safety box 3 is located in the limiting groove, thereby restricting the movement of the support member 2 along its length. Furthermore, the support member 2 needs to be tilted, with the upper end of the support member 2 abutting in the support groove.

[0047] In other embodiments, the support groove is formed on the side of the support plate 31 facing the support member 2. It is understood that the plate-like structure has a certain thickness, i.e., the side has a certain height. The depth of the support groove formed on this side is parallel to the surface of the support plate 31. One end of the support member 2 extends into the support groove, thus providing support to the support plate 31. Optionally, the support groove can be trough-shaped or a through structure, i.e., a through hole is formed on the side, and the extension direction of the through hole is parallel to the surface of the support plate 31.

[0048] Optionally, the safety box 3 has a first sidewall 32 and a second sidewall 33 disposed opposite to each other. In some embodiments, the support member 2 includes a first support member and a second support member. The first support member is inserted into the first sidewall 32 and supports the bottom surface of the support plate 31, and the second support member is inserted into the second sidewall 33 and supports the bottom surface of the support plate 31. Of course, it is also necessary to open a support groove in the support plate 31 so that one end of both the first support member and the second support member is located in the support groove. The specific opening position can be referred to the example above.

[0049] Optionally, in this embodiment, there are two support plates 31, which can open and close relative to each other. The test piece 100 is placed in the middle of the two support plates 31, and the two support plates 31 fall to one side of the middle, so that the test piece 100 will fall into the cooling flame retardant material.

[0050] Optionally, in this embodiment, two support members 2 are provided, each supporting one of the two support plates 31. Of course, in other embodiments, only one support member 2 can be provided, supporting one of the two support plates 31, which in turn supports the other support plate 31. For example, an edge can be provided on the side of the first support plate 31 near the other support plate 31, the edge being lower than the plate surface and located below the other support plate 31.

[0051] Optionally, the conductive components include two sets: one set of conductive components is used to connect the tab 101 of the positive terminal of the device under test 100 to one port of the charging and discharging device 1, and the other set of conductive components is used to connect the tab 101 of the negative terminal of the device under test 100 to another port of the charging and discharging device 1.

[0052] Optionally, each set of conductive components includes a first wire 5 and a second wire 6. One end of the first wire 5 and one end of the second wire 6 are electrically connected, and the other end of the first wire 5 is electrically connected to the charging / discharging device 1. The other end of the second wire 6 is electrically connected to the device under test 100. A pluggable connector 4 is disposed on the first wire 5. That is, the first wire 5 is further divided into a first segment and a second segment. One end of the first segment is provided with the first end 41 of the pluggable connector 4, and one end of the second segment is provided with the second end 42 of the pluggable connector 4. The first end 41 and the second end 42 of the pluggable connector 4 can be quickly inserted to achieve electrical conduction and quickly removed to achieve electrical disconnection.

[0053] Optionally, each conductive assembly further includes a conductive base 7 and a conductive post 8. The conductive base 7 is mounted on the support plate 31, and the conductive post 8 is vertically connected to the conductive base 7. A conductive ring 9 at one end of the first wire 5 is fitted onto the conductive post 8, and a conductive ring 9 at one end of the second wire 6 is fitted onto the conductive post 8. By fitting the conductive rings 9 of both the first wire 5 and the second wire 6 onto the conductive post 8, the first wire 5 and the second wire 6 can be quickly made conductive. Furthermore, by using the conductive base 7 and the conductive post 8, the conductive area of ​​the first wire 5 and the second wire 6 can be increased, preventing excessively high local temperatures due to insufficient conductive area, thus further improving the safety of the experiment.

[0054] Optionally, the conductive base 7 is detachably connected to the support plate 31, which is made of an insulating material, or the conductive base 7 has an insulating pad underneath to separate the conductive base 7 from the support plate 31.

[0055] Optionally, the conductive post 8 is an insulating post with a metal layer on its surface. Since the insulating post is lighter, the weight of the objects on the support plate 31 can be reduced, the support strength requirement of the support member 2 can be reduced, and the overall weight of the safety box 3 is lighter, which is conducive to handling.

[0056] Optionally, one end of the second wire 6 is connected to the first wire 5, and the conductive terminal 10 at the other end of the second wire 6 is connected to the tab 101 of the device under test 100. In this embodiment, the conductive terminal 10 at the other end of the second wire 6 can be directly placed on the tab 101, and sufficient contact between the two is sufficient to ensure continuity. If the conductive terminal 10 is fixedly connected to the tab 101, it is necessary to ensure that the length of the second wire 6 is sufficient to support the battery falling into the water tank and being immersed in water.

[0057] Optionally, the battery testing system also includes a temperature sensor, which is disposed on the device under test 100 and is used to detect the temperature of the device under test 100.

[0058] Optionally, the battery testing system also includes a monitoring module. A temperature sensor is communicatively connected to the monitoring module. The temperature sensor transmits the real-time battery temperature signal to the monitoring module. The monitoring module determines whether the temperature exceeds a high-temperature threshold based on the temperature signal. If the temperature exceeds the threshold, a warning signal is sent to a warning device to alert personnel. This allows them to quickly disconnect the charging / discharging equipment 1 from the battery under test and immerse the battery in cooling and flame-retardant materials to extinguish any fire, further ensuring testing safety. The warning device can be a warning light or a buzzer, etc., without further restrictions.

[0059] Optionally, in this embodiment, the cooling flame retardant is water, and the safety box 3 has a sealable drain outlet on its side wall or bottom wall to facilitate the drainage of water from the tank. Of course, in other embodiments, the cooling flame retardant can also be other types of coolant.

[0060] Optionally, in some embodiments, a liquid level indicator is provided inside the safety box 3 to ensure that water can submerge the entire battery. In other embodiments, a liquid level sensor may also be provided inside the safety box 3, communicating with the monitoring module, to trigger an alarm when the liquid level is lower than the safe level.

[0061] The safety box 3 of the battery testing system contains cooling and flame-retardant materials, and the top of the safety box 3 can be opened. In the event of a battery fire, the top can be opened quickly, allowing the battery to fall into the cooling and flame-retardant materials to extinguish the fire and prevent greater damage and losses.

[0062] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
