[0033] According to one aspect of the present application, a battery testing device is provided, which is used to test a battery. The battery testing device includes a base 1, a cover 2 and a moving component 3. The cover 2 has an opening. The moving component 3 is arranged on the base 1. The moving component 3 can drive the cover 2 to move between a first position and a second position. When the cover 2 is in the first position, the cover 2 abuts against the base 1, and the base 1 closes the opening. The cover 2 and the base 1 enclose an accommodation space, and the accommodation space is used to accommodate the battery. When the cover 2 is in the second position, the cover 2 is separated from the base 1.

[0034] When the battery test device of the present application is used, the cover 2 can be first driven to move to the second position by the moving component 3, so that the cover 2 is separated from the base 1, and the battery can be moved between the cover 2 and the base 1. Then the moving component 3 drives the cover 2 to move to the second position, so that the battery is enclosed in the placement space surrounded by the cover 2 and the base 1. By cooperating with the base 1 and the cover 2, the sealing effect of the battery can be guaranteed, and the battery can be prevented from being affected by the air convection formed by the air inlet and outlet of the test box. At the same time, the moving component 3 drives the cover 2 to move, so that the battery test device can be reused, thereby reducing the cost of the battery thermal management test.

[0035] like Figure 1 and Figure 2 As shown, the cover shell 2 is in a rectangular parallelepiped shape, and the lower end of the cover shell 2 is open to form an opening. When the moving component 3 drives the cover shell 2 to move to the second position, the base 1 closes the opening.

[0036] Furthermore, if Figure 1As shown, the lower end of the moving component 3 is fixed on the base 1, and the upper end of the moving component 3 is in contact with the cover 2. The moving component 3 can be extended and retracted in a direction perpendicular to the base 1, thereby driving the cover 2 to move in a direction perpendicular to the base 1. The moving component 3 is extended to drive the cover 2 to move away from the base 1. When the moving component 3 drives the cover 2 to move to the first position, as shown in FIG. Figure 3 As shown, the gap between the lower end of the cover 2 and the base 1 allows the battery to move, so that the battery can move to the base 1 through the gap between the cover 2 and the base 1. The moving component 3 contracts and can drive the cover 2 to move toward the base 1. When the moving component 3 drives the cover 2 to move to the second position, as shown in FIG. Figure 4 As shown, the lower end of the cover shell 2 abuts against the base 1 , so that the opening of the cover shell 2 is closed by the base 1 , and the battery is enclosed in the placement space surrounded by the base 1 and the cover shell 2 .

[0037] In addition, there may be multiple movable components 3 , and the multiple movable components 3 are spaced apart on the base 1 . The multiple movable components 3 are all in contact with the cover 2 , and the multiple movable components 3 can jointly drive the movement of the cover 2 .

[0038] Optionally, the base 1 can be in the shape of a plate, and the number of the movable components 3 can be four, and the four movable components 3 are respectively arranged at the four corners of the base 1, and the four movable components 3 respectively support the four corners of the cover shell 2, thereby ensuring the stability of the movement of the cover shell 2.

[0039] Optionally, the moving component 3 may be a telescopic structure such as a hydraulic rod, an electric telescopic rod, etc. Preferably, the moving component 3 is a hydraulic rod.

[0040] In addition, the cover shell 2 can be driven to move by the extension and retraction of the moving device without the need to manually lift and place the cover shell 2, thereby improving the convenience of the thermal management test and ensuring the consistency of the sealing state of the cover shell 2 each time it is placed on the base 1.

[0041] In the embodiments of the present application, Figure 1 and Figure 2 As shown, a wiring hole 21 is provided on the housing 2, and the wiring hole 21 penetrates the housing 2, so that the wiring harness 8 can be connected to the battery in the housing 2 through the wiring hole 21. The battery testing device also includes a cover 7, which is arranged on one side of the wiring hole 21. The cover 7 can rotate relative to the housing 2, so that the cover 7 can cover the wiring hole 21, or be removed from the wiring hole 21. When the battery testing device is in a non-testing state, the cover 7 can close the wiring hole 21. When the test is being performed, the cover 7 is opened, so that the wiring harness 8 can enter the housing 2 through the wiring hole 21.

[0042] Optionally, the housing 2 may be made of a material with good insulation and flame retardancy such as PC (Polycarbonate) or ABS (AcrylonitrileButadieneStyrene). The surface of the housing 2 is provided with an insulating layer, which may be a layered structure formed by solidifying an insulating varnish applied on the surface of the housing 2. In this way, the housing 2 has good insulation performance, which improves the safety of the battery during testing in the placement space.

[0043] In an embodiment of the present application, the base 1 can be a steel structure, and an insulating layer formed by solidifying the insulating paint is also provided on the surface of the base 1. A ventilation hole 11 is opened on the base 1, and the ventilation hole 11 penetrates the base 1 in a direction perpendicular to the base 1.

[0044] Furthermore, a plurality of ventilation holes 11 are provided on the base 1, and the plurality of ventilation holes 11 can be arranged at equal intervals. Thus, the entire base 1 is a hollow design, which can facilitate simulation of the state of the battery on the entire vehicle.

[0045] In an embodiment of the present application, the battery test device includes wheels 4 and a handle 5, wherein the wheels 4 are arranged on the side of the base 1 facing away from the cover 2, and the handle 5 is fixed on the base 1. The handle 5 may include a connecting rod and a handle, wherein the connecting rod is connected to the end of the base 1, and the connecting rod is inclined relative to the base 1, and the handle is connected to the end of the connecting rod away from the base 1. In this way, the entire battery test device can be moved by pushing the handle 5, which enables the battery test device to be used as a battery transport vehicle, and the batteries placed inside can be protected from rain, thereby reducing the risk of transportation on rainy days.

[0046] Optionally, the wheel 4 may be a universal wheel.

[0047] Furthermore, if Figure 1 and Figure 2 As shown, the battery test device further includes a support assembly 6, which is detachably connected to the side of the base 1 facing away from the cover 2, and the size of the support assembly 6 in the direction perpendicular to the base 1 is larger than the size of the wheel 4 in the direction perpendicular to the base 1. When the battery test device is moving, the support assembly 6 is not installed on the base 1. When the battery test device is moved, the support assembly 6 is installed on the base 1. Since the size of the support assembly 6 in the direction perpendicular to the base 1 is larger than the size of the wheel 4 in the direction perpendicular to the base 1, the support assembly 6 can prop up the base 1, so that the wheel 4 is suspended in the air, thereby preventing the battery test device from sliding during the test process.

[0048] Optionally, the support assembly 6 may include a screw rod and a support column connected to each other, and a threaded hole is provided at the bottom of the base 1. The screw rod cooperates with the threaded hole to achieve a detachable connection between the support assembly 6 and the base 1.

[0049] Furthermore, there may be multiple support assemblies 6 , and the multiple support assemblies 6 jointly support the base 1 . Preferably, there are four support assemblies 6 , and the four support assemblies 6 are respectively arranged at the four corners of the base 1 .

[0050] The use process of the battery test device of this application is as follows:

[0051] (1) driving the cover 2 to move to the second position through the moving component 3 to place the battery sample on the base 1;

[0052] (2) Push the push handle 5 to push the entire battery test device into the test box;
