Description

Technical Field

[0002] Electric vehicle batteries fall into two main categories: rechargeable batteries and fuel cells. Rechargeable batteries are suitable for pure electric vehicles and include lead-acid batteries, nickel-metal hydride batteries, sodium-sulfur batteries, secondary lithium batteries, air batteries, and ternary lithium batteries. The specific types vary slightly depending on the type of electric vehicle. In pure electric vehicles equipped solely with rechargeable batteries, the battery serves as the sole power source for the vehicle's drive system.

[0003] During the production process of lithium batteries, power-on testing is required to troubleshoot battery faults, thereby determining the quality and discharge status of the battery. This plays a crucial role in battery fault diagnosis.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 3 As shown, the present invention provides an electric vehicle power battery fault detection component, including a support base plate 1, support vertical plates 3 and a detector body 8. The bottom ends of the two sets of support vertical plates 3 are vertically fixed to the top of the support base plate 1, and the two sets of support vertical plates 3 are respectively located at the center of the top edge of the support base plate 1. The detector body 8 is embedded in one side wall of the support vertical plate 3, and a display screen is installed on the surface of the detector body 8.

[0026] refer to Figure 1 The bottom of the support base plate 1 is vertically fixedly connected with several sets of fixed support legs 2, and the several sets of fixed support legs are respectively located at the bottom corner of the support base plate 1. The top of the support base plate 1 is provided with a limiting groove 4, the central axis of the limiting groove 4 coincides with the central axis of the support base plate 1, and several sets of rotating rollers 5 are installed inside the limiting groove 4. The several sets of rotating rollers 5 are all distributed at equal intervals with the central axis of the limiting groove 4 as the center.

[0027] The rotating roller 5 rotates inside the limiting groove 4. A connecting beam 6 is provided above the supporting base plate 1. The two ends of the connecting beam 6 are fixedly connected to the opposite side walls of the supporting vertical plate 3. The connecting beam 6 is located at the top of the side wall of the supporting vertical plate 3. A winding cylinder 7 is provided above the supporting base plate 1. The winding cylinder 7 is slidably sleeved on the surface of the connecting beam 6. A limiting groove 9 is opened at the top of the supporting base plate 1. The limiting groove 9 is located on one side of the limiting groove 4. The limiting groove 9 is perpendicular to the limiting groove 4.

[0028] As a technical optimization of this utility model, by using several sets of rotating rollers 5 inside the limiting groove 4, when the tester moves the battery to the surface of the support base plate 1 and places it on the rotating rollers 5, it is convenient to move and adjust the battery from the edge to the center of the support base plate 1. This saves time and effort and is easy to operate, reducing the friction between the battery and the equipment during manual handling and adjustment, thereby reducing the wear of the battery by the equipment.

[0029] refer to Figure 2 The limiting slide groove 9 is equipped with a threaded rod 10, and the surface of the threaded rod 10 is threadedly connected to a movable slider 11. The movable slider 11 is slidably fitted inside the limiting slide groove 9. A connecting support rod 12 is slidably fitted inside the limiting slide groove 9. A clamping panel 13 is fitted to the surface of the supporting base plate 1.

[0030] An anti-slip pad 14 is attached to one side wall of the clamping panel 13. One end of the connecting rod 12 is fixedly connected to the movable slider 11, and the other end of the connecting rod 12 is fixedly connected to the bottom center of the clamping panel 13. An adjusting turntable 15 is installed on one side wall of the supporting base plate 1, and the adjusting turntable 15 is connected to one end of the threaded rod 10.

[0031] As a technical optimization of this utility model, by setting the clamping panel 13, the operator can rotate the adjusting turntable 15 to drive the threaded rod 10 to rotate, so that the moving slider 11 moves horizontally on the surface of the threaded rod 10, thereby driving the connecting support rod 12 to move and driving the clamping panel 13 to move on the surface of the support base plate 1. This can limit and fix the battery placed on the surface of the support base plate 1, preventing the battery from moving on the surface of the rotating roller 5 during the testing process.

[0032] refer to Figure 3 The support vertical plate 3 has a heat dissipation hole 19 on one side wall. The heat dissipation hole 19 is connected to the detector body 8. A connecting wire 16 is installed on the surface of the detector body 8. The connecting wire 16 is made of pure copper. One end of the connecting wire 16 passes through the interior of the connecting beam 6 and connects to the detector body 8.

[0033] The other end of the connecting wire 16 passes through the surface of the connecting beam 6 and is wound around the surface of the winding drum 7. One end of the connecting wire 16 is connected to a receiving end 17. The receiving end 17 is electrically connected to the detector body 8 through the connecting wire 16. One end of the receiving end 17 is connected to two sets of battery fixing clips 18. The battery fixing clips 18 are electrically connected to the receiving end 17.

[0034] As a technical optimization of this utility model, by setting two sets of battery fixing clips 18, the battery fixing clips 18 are connected to the positive and negative terminals of the battery. By setting the winding drum 7, the connecting wire 16 is wound around the surface of the winding drum 7. Then, by sliding the winding drum 7 on the surface of the connecting beam 6, the connecting wire 16 and the receiving end 17 can be moved and adjusted according to the battery position. It is also convenient to store and organize the connecting wire 16 to prevent the wire from being scattered, torn or damaged. Furthermore, by setting the heat dissipation hole 19, the detector body 8 embedded in the support vertical plate 3 can be cooled.

[0035] The working principle and usage process of this utility model are as follows: First, the tester moves the battery to the surface of the support base plate 1 and places it on the rotating roller 5. The battery is then moved from the edge of the support base plate 1 to the center. Next, the operator rotates the adjusting turntable 15, causing the threaded rod 10 to rotate. This causes the sliding block 11 to move horizontally on the surface of the threaded rod 10, thereby moving the connecting support rod 12 and simultaneously moving the clamping panel 13 on the surface of the support base plate 1. This effectively limits and fixes the battery placed on the surface of the support base plate 1. Finally, the battery fixing clamp 18 is connected to the positive and negative terminals of the battery. A suitable discharge current and a suitable termination voltage are selected according to the battery capacity. The tester body 8 is then started. The instrument records the discharge time and displays the battery voltage. During the discharge process, the battery voltage is monitored. When the voltage drops to the termination voltage, the discharge stops, thus completing the test.

[0036] In summary, this electric vehicle power battery fault detection component, through the use of the rotating roller 5 in conjunction with the clamping panel 13, allows workers to easily move the battery from the edge to the center of the support base plate 1, saving manpower. By rotating the adjusting turntable 15, the threaded rod 10 is rotated, causing the sliding slider 11 to move horizontally on the surface of the threaded rod 10. This, in turn, moves the connecting support rod 12 and the clamping panel 13 on the surface of the support base plate 1, thus limiting and fixing the battery placed on the surface of the support base plate 1. This solves the problems of the large weight of automobile batteries, the inconvenience of manual handling during testing, and the friction between the bottom of the battery and the equipment during handling, which can easily cause battery damage and affect the safety of subsequent use of the battery.
