[0046] This embodiment provides a battery detection device, which can detect whether the tab length of a battery is qualified and give a warning, and at the same time can use this battery detection device to test the battery performance. As Figures 1 - 3 shown, the battery detection device includes a jig 10, a first test piece 21, a second test piece 22, a first conductive piece 31, a second conductive piece 32, a first warning piece 41 and a second warning piece 42. The jig 10 is provided with a limiting groove 11 and a first tab groove 12 and a second tab groove 13 communicating with the limiting groove 11. The limiting groove 11 is used to accommodate the battery pack body; the first test piece 21 is located at one end of the first tab groove 12 away from the limiting groove 11, and the second test piece 22 is located at one end of the second tab groove 13 away from the limiting groove 11; one end of the first conductive piece 31 is configured to be electrically connected to the first tab placed in the first tab groove 12, and one end of the second conductive piece 32 is configured to be electrically connected to the second tab placed in the second tab groove 13; one end of the first warning piece 41 (hereinafter referred to as the first end 411, which is also indicated in the figure) is electrically connected to the first test piece 21, the other end of the first warning piece 41 (hereinafter referred to as the second end 412, which is also indicated in the figure) is electrically connected to the other end of the second conductive piece 32, one end of the second warning piece 42 (hereinafter referred to as the fourth end 422, which is also indicated in the figure) is electrically connected to the second test piece 22, and the other end of the second warning piece 42 (hereinafter referred to as the third end 421, which is also indicated in the figure) is electrically connected to the other end of the first conductive piece 31.

[0047] Among them, the battery pack body and the first tab and the second tab connected to the battery pack body form a complete battery pack. One of the first tab and the second tab is the positive tab, and the other is the negative tab. When referring to the tab hereinafter, it refers to the first tab and the second tab.

[0048] When the above battery detection device performs battery pack detection, the battery pack body is placed in the limiting groove 11, ensuring that the battery pack body on the side where the tab is connected fits against the corresponding side wall of the limiting groove 11. When the tab length is qualified, that is, the first tab only contacts the first conductive member 31 and does not contact the first test member 21, and the second tab only contacts the second conductive member 32 and does not contact the second test member 22. At this time, both the first warning member 41 and the second warning member 42 are conductive, indicating that the tab length is qualified. After confirming that the tab length is qualified, the two poles of the instrument used to test the battery pack performance are respectively electrically connected to the first conductive member 31 and the second conductive member 32 to test the battery pack performance, and the performance of the battery pack is judged according to the display result of the instrument; when the length of the first tab is too long and the length of the first tab groove 12 is insufficient, causing the first tab to abut against the first test member 21, at this time, the first end 411 of the first warning member 41 is conductive to the first tab due to being electrically connected to the first test member 21, and the second end 412 of the first warning member 41 is electrically connected to the second conductive member 32 and thus conductive to the second tab. The battery pack supplies power to the first warning member 41, causing the first warning member 41 to send out a warning message, indicating that the length of the first tab is unqualified; when the length of the second tab is too long and the length of the second tab groove 13 is insufficient, causing the second tab to abut against the second test member 22, at this time, the fourth end 422 of the second warning member 42 is conductive to the second tab due to being electrically connected to the second test member 22, and the third end 421 of the second warning member 42 is electrically connected to the first conductive member 31 and thus conductive to the first tab. The battery pack supplies power to the second warning member 42, causing the second warning member 42 to send out a warning message, indicating that the length of the second tab is unqualified. Similarly, when both the length of the first tab and the length of the second tab are unqualified, the first warning member 41 and the second warning member 42 send out warning messages at the same time. That is, this battery test device can conveniently detect the length of the tab and give a prompt when the tab length is too long. At the same time, the performance of the battery pack can be tested through this battery test device.

[0049] Optionally, refer to Figure 1 and Figure 2, the first conductive member 31 includes a first connecting plate 311 and a first supporting member 312 protruding from the first connecting plate 311. The first supporting member 312 passes through the bottom of the first tab groove 12 and protrudes from the first tab groove 12. The first supporting member 312 is used to support the first tab, and the first connecting plate 311 is electrically connected to the other end of the second warning member 42; the second conductive member 32 includes a second connecting plate 321 and a second supporting member 322 protruding from the second connecting plate 321. The second supporting member 322 passes through the bottom of the second tab groove 13 and protrudes from the second tab groove 13. The second supporting member 322 is used to support the second tab, and the second connecting plate 321 is electrically connected to the other end of the first warning member 41. Through the above arrangement, the first supporting member 312 is located at the bottom of the first tab groove 12. When the first tab is placed in place, it is easier to contact the first supporting member 312, thereby achieving good electrical conduction; the second supporting member 322 is located at the bottom of the second tab groove 13. When the second tab is placed in place, it is easier to contact the second supporting member 322, thereby achieving good electrical conduction.

[0050] In other embodiments, the first supporting member 312 and the second supporting member 322 may also be at other positions of the corresponding tab grooves, which are not limited herein.

[0051] Optionally, the battery detection device further includes a tab pressing member (not shown). The tab pressing member is used to press the first tab against the first conductive member 31, and / or the tab pressing member is used to press the second tab against the second conductive member 32. Through the above arrangement, it can ensure the close fit between the tab and the corresponding supporting member.

[0052] Among them, the tab pressing member can be an independent block. When the tab needs to be pressed, the tab pressing member can be taken and used, and the tab is pressed by the gravity of the tab pressing member. Optionally, the tab pressing member can also be connected to the fixture 10 through an elastic member. When the battery pack is not placed, the tab pressing member abuts against the first supporting member 312 and the second supporting member 322 by the elasticity of the elastic member. When the tab needs to be placed, the tab pressing member is lifted against the elastic force of the elastic member, and the tab is placed in the corresponding tab groove, and then the tab can be pressed by the dual action of the elastic force and the gravity.

[0053] Optionally, as Figure 1 and Figure 3As shown, the first tab slot 12 and the second tab slot 13 are located on the same side of the limit slot 11. The battery detection device further includes a mounting block 50. The mounting block 50 is located on the side of the first test piece 21 away from the first tab slot 12. The first locking assembly 61 locks the first connecting plate 311 to the mounting block 50 and is electrically connected to the second test piece 22. The second locking assembly 62 locks the second connecting plate 321 to the mounting block 50 and is electrically connected to the first test piece 21. By adding the design of the mounting block 50 and using the first locking assembly 61 and the second locking assembly 62, the ends of the first connecting plate 311 and the second connecting plate 321 are better fixed, making the overall appearance more regular.

[0054] Optionally, as Figure 1 and Figure 3 shown, the first locking assembly 61 includes a first screw 611 and a first connecting ring 612. The first screw 611 sequentially passes through the first connecting ring 612 and the first connecting plate 311 and is threadedly connected to the mounting block 50. The first connecting ring 612 is electrically connected to the second warning piece 42. The second locking assembly 62 includes a second screw 621 and a second connecting ring 622. The second screw 621 sequentially passes through the second connecting ring 622 and the second connecting plate 321 and is threadedly connected to the mounting block 50. The second connecting ring 622 is electrically connected to the first warning piece 41. That is to say, the first connecting ring 612 and the third end 421 are connected by a wire. The head of the first screw 611 presses the first connecting ring 612 against the first connecting plate 311. The rod portion of the first screw 611 passes through the first connecting ring 612 and is connected to the mounting block 50, which can more quickly realize the electrical connection between the first connecting plate 311 and the third end 421. The same is true for the second screw 621 and the second connecting ring 622, which will not be elaborated here.

[0055] It should be noted that in order to make the illustrated structure less blocked, Figure 1 and Figure 3 the wires are illustrated with thick lines in

The second connecting plate 321 is L-shaped, and both sides of the second connecting plate 321 are in contact with the side surface and the bottom surface of the mounting block 50. Through the above settings, the first connecting plate 311 and the second connecting plate 321 are better in contact with the mounting block 50.

[0057] Furthermore, as Figure 3As shown, the mounting block 50 is provided with a first avoidance groove 51 corresponding to the first connecting plate 311 and the second connecting plate 321. The first connecting plate 311 and the second connecting plate 321 are received in the corresponding first avoidance groove 51. After installation, the surface of the mounting block 50 has no protruding structure, and it plays a role in initially positioning the installation of the first connecting plate 311 and the second connecting plate 321.

[0058] Optionally, as Figure 2 shown, the bottom side of the jig 10 is provided with a second avoidance groove 14 corresponding to the first connecting plate 311 and the second connecting plate 321, so that the horizontal portions of the first connecting plate 311 and the second connecting plate 321 can be received in the corresponding second avoidance groove 14, ensuring the flatness of the bottom side of the jig 10.

[0059] Optionally, as Figure 1 and Figure 3 shown, the battery detection device further includes a third locking assembly 63. The third locking assembly 63 includes a third screw 631 and a third connecting ring 632. The third screw 631 passes through the third connecting ring 632 and is threadedly connected to the mounting block 50. The third screw 631 is electrically connected to the first test piece 21, and the third connecting ring 632 is electrically connected to the first warning piece 41. The battery detection device further includes a fourth locking assembly 64. The fourth locking assembly 64 includes a fourth screw 641 and a fourth connecting ring 642. The fourth screw 641 passes through the fourth connecting ring 642 and is threadedly connected to the mounting block 50. The fourth screw 641 is electrically connected to the first test piece 21, and the fourth connecting ring 642 is electrically connected to the second warning piece 42. Through the above settings, the head of the third screw 631 clamps the third connecting ring 632 on the mounting block 50. The third connecting ring 632 and the first end 411 are connected by a wire, and the rod portion of the third screw 631 and the first test piece 21 are electrically connected, making the electrical connection between the first end 411 and the first test piece 21 convenient, stable and fast. The function of the fourth locking assembly 64 is similar and will not be elaborated here.

[0060] Furthermore, the circumferential direction of the rod portion of the first screw 611 is threadedly connected to the first test piece 21 to ensure the tightness of the electrical connection. Furthermore, the first screw 611 is also threadedly connected to the jig 10. Thus, the first screw 611 and the fourth screw 641 also jointly realize the connection between the mounting block 50 and the jig 10.

[0061] Optionally, both the first warning member 41 and the second warning member 42 are mounted on the mounting block 50. That is, the mounting block 50 provides a mounting surface for the installation of the first warning member 41 and the second warning member 42, making the device more tidy and improving the operation convenience for the operator. In this embodiment, both the first warning member 41 and the second warning member 42 are lamps, which emit bright light when the tab length is unqualified, and the colors of the first warning member 41 and the second warning member 42 are different, so that the operator can easily distinguish whether the unqualified tab is the first tab or the second tab. In other embodiments, the first warning member 41 and the second warning member 42 can also be buzzers or other warning forms, which are not limited herein.

[0062] Optionally, both the first warning member 41 and the second warning member 42 are mounted on the PCB board 70, and the PCB board 70 is mounted on the top of the mounting block 50. Through the above settings, the installation of the first warning member 41 and the second warning member 42 is facilitated. In addition, short-circuit protection and other settings can also be made on the PCB board 70 to prevent the operator from misoperating.

[0063] Optionally, as Figure 2 and Figure 3 shown, the battery detection device further includes a bottom support plate 80, and the jig 10 and the mounting block 50 are both connected to the bottom support plate 80.

Through the above settings, the bottom support plate 80 not only integrates the jig 10 and the mounting block 50, but also facilitates the insertion of the two poles of the tester. After the two poles of the tester are respectively inserted into the first slot 81 and the second slot 82 and then slightly lifted upward, the plug located in the first slot 81 contacts the first connecting plate 311, and the plug located in the second slot 82 contacts the second connecting plate 321, so as to realize the relatively rapid testing of the performance of the battery pack.

[0064] In addition, for a tester with jaws on the plug, the jaws of the two poles can be directly clamped on the first screw 611 and the second screw 621 respectively, and the performance test of the battery pack can also be realized relatively quickly.
