Description

Technical Field

[0001] The present disclosure relates to the technical field of battery detection devices, and in particular to a battery test connector. Background Art

[0002] The charge and discharge test of energy storage batteries is a necessary means to verify the performance of energy storage batteries. When performing charge and discharge tests on batteries, in addition to electrical physical parameters such as voltage and current, the temperature change characteristics are also the most noteworthy physical characteristics. This is because the heat generation characteristics of the battery are crucial to the heat dissipation design and thermal runaway protection of the energy storage battery. Battery temperature monitoring is crucial for in-situ research and safety design of the battery.

[0003] When the battery is in use, the internal tabs of the battery heat up, causing the overall temperature of the battery to rise. It is difficult to monitor the actual temperature changes inside the battery by using a platinum resistance sensor or an optical fiber sensor attached to the battery to monitor the external temperature of the battery. Therefore, the sensor is usually embedded inside the battery, and one end of the sensor is led out to the outside of the battery to monitor the temperature changes inside the battery through the sensor. However, the embedded installation of the sensor inside the battery will affect the sealing and internal structure of the battery. The existing method of monitoring battery temperature is difficult to accurately monitor the temperature changes inside the battery without affecting the sealing and internal structure of the battery.

[0029] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0031] First, the structure of the battery to be tested 7 usually includes a shell, a positive ear, a negative ear and two bolts. The positive ear and the negative ear are arranged inside the shell. A process hole 71 is provided on the shell, which is respectively opposite to the positive ear and the negative ear. The two bolts are passed through the two through holes. The positive ear and the negative ear are both sheet structures. Screw holes are provided on the positive ear and the negative ear, so that the two bolts are threadedly connected to the screw holes of the positive ear and the negative ear respectively. The heads of the two bolts are exposed on the outside of the shell. The external equipment is connected to the two bolts to complete the electrical connection operation with the battery to be tested 7, that is, the inside of the conventional battery is provided with ear, and the shell of the battery is provided with a process hole 71 for plugging in the bolts.

[0032] Reference Figures 1 to 6 As shown, the present application provides a battery test connector, including a plug-in portion 2, a detection portion 1 and a temperature measuring device; the detection portion 1 is connected to one side of the plug-in portion 2, and a thread is provided on the outer side of the plug-in portion 2, the plug-in portion 2 is used to be inserted into the process hole 71 of the battery 7 to be tested and is threadedly connected to the screw hole on the pole ear inside the battery 7 to be tested, and the plug-in portion 2 or the detection portion 1 is used to be connected to the detection line of the detection device; a side of the detection portion 1 facing away from the plug-in portion 2 is recessed to form a receiving groove 11, and the receiving groove 11 extends along the direction of the detection portion 1 toward the plug-in portion 2 to an end of the plug-in portion 2 away from the detection portion 1, and the detection line 4 of the temperature measuring device is arranged in the receiving groove 11, and the detection line 4 extends to the bottom of the receiving groove 11.

[0033] The plug-in portion 2 can pass through the process hole 71 and be threadedly connected to the screw hole on the pole ear, so that the plug-in portion 2 and the detection portion 1 can serve as an electrical connection structure on the battery housing connected to an external device. At the same time, the detection line 4 enters the receiving groove 11 through the notch of the receiving groove 11, and the detection line 4 extends in the receiving groove 11 along the detection portion 1 toward the plug-in portion 2, so that the end of the detection line 4 is located at the bottom of the receiving groove 11, and the end of the detection line 4 is spaced from the bottom of the receiving groove 11, thereby avoiding the end of the detection line 4 from contacting the bottom of the receiving groove 11 and being damaged.

[0034] The above-mentioned detection line 4 is located at the bottom of the receiving groove 11, so that the detection line 4 is located inside the plug-in part 2 near the connection between the plug-in part 2 and the pole lug, so that the detection line 4 can collect the temperature of the connection between the plug-in part 2 and the pole lug. The detection line 4 can choose to enter the receiving groove 11 through the notch of the receiving groove 11, and the detection line 4 moves in the direction of the groove bottom of the receiving groove 11. The end of the detection line 4 and the groove bottom of the receiving groove 11 are spaced apart. The end of the detection line 4 and the groove bottom of the receiving groove 11 can be selected to have a spacing of 1 mm to 3 mm to avoid the end of the detection line 4 directly contacting the groove bottom of the receiving groove 11 and being damaged. At the same time, the distance between the end of the detection line 4 and the groove bottom of the receiving groove 11 is close, so that the temperature of the receiving groove 11 is transmitted to the end of the detection line 4. The loss is small, so that the temperature data collected by the detection line 4 can still accurately reflect the temperature conditions inside the battery 7 to be tested.

[0035] Since the plug-in portion 2 uses the process hole 71 that the battery 7 to be tested has, the detection line 4 of the battery test connector can enter the interior of the battery 7 to be tested along with the plug-in portion 2 to monitor the temperature inside the battery 7 to be tested, thereby avoiding the detection line 4 being embedded in the interior of the battery 7 to be tested and affecting the sealing and internal structure of the battery.

A set spacing can be selected between the bottom of the receiving groove 11 and the side of the plug-in part 2 facing away from the detection part 1. The value of the set spacing is determined according to the size of the plug-in part 2. It is sufficient to ensure that the heat of the tab is lost between the side of the plug-in part 2 facing away from the detection part 1 and the bottom of the receiving groove 11, which will not affect the accuracy of the data collected by the detection line 4. The receiving groove 11 can be selected as a groove body with a cylindrical cross section, and of course, the cross section of the receiving groove 11 can also be selected as a circular cross section.

[0039] The detection line 4 of the temperature measuring device can be selected as an optical fiber, the head of the optical fiber is connected to the device, and the end of the bottom of the optical fiber is engraved with a fiber grating for temperature monitoring. The end of the bottom of the optical fiber is also sheathed with a copper sleeve or a copper-plated film for packaging to protect the fiber grating. Of course, the detection line 4 can also be selected as a wire, one end of the wire is connected to the temperature measuring device, and the other end is provided with a platinum resistance sensor, so that the platinum resistance sensor monitors the temperature of the pole ear at the bottom of the receiving groove 11.

The detection device is electrically connected to the pole tab of the battery 7 to be tested, so that the detection device can perform charging and discharging detection operations on the battery 7 to be tested.

[0041] When the battery test connector provided by the embodiment of the present disclosure is used, the bolts on the battery 7 to be tested are removed, the plug-in portion 2 is passed through the process hole 71 of the battery 7 to be tested and is threadedly connected to the screw hole of the pole ear in the battery 7 to be tested, and the detection wire 4 is inserted into the receiving groove through the notch of the receiving groove 11. After the detection wire 4 is extended into the receiving groove 11, it moves toward the bottom of the receiving groove 11, so that the end of the detection wire 4 is located at the bottom of the receiving groove 11, and the detection wire 4 is spaced from the bottom of the receiving groove 11 to avoid damaging the detection wire 4, that is, the end of the detection wire 4 can be located inside the battery 7 to be tested in the receiving groove 11 near the pole ear.

[0042] The detection line of the detection device is connected to the plug-in part 2, so that the detection device is electrically connected to the pole ear of the battery to be tested 7 through the plug-in part 2 and the detection part 1. The detection device performs charging and discharging detection on the battery to be tested 7. The detection line 4 collects the temperature changes of the pole ear during the charging and discharging process of the battery to be tested 7, so that the temperature measuring device can monitor the internal temperature of the battery to be tested 7.

[0044] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, in some embodiments, the battery test connector further includes an electrical connector 6, which is connected to one of the plug-in portion 2 and the detection portion 1, and is connected to a detection line of a detection device, so that the detection device is electrically connected to the plug-in portion 2 or the detection portion 1 through the electrical connector 6. With such a configuration, the electrical connector 6 can be used to connect to the detection line of the detection device, avoiding the difficulty of connecting the detection line to the detection portion 1 or the plug-in portion 2 due to the large volume of the detection portion 1 and the plug-in portion 2 being located inside the battery 7 to be tested, and facilitating the user to electrically connect the detection line of the detection device to the plug-in portion 2 and the detection portion 1.

[0045] Specifically, the electrical connector 6 can be selected as a metal sheet or a metal plate, one end of the electrical connector 6 is connected to the outside of the detection part 1 or the plug part 2, and the other end extends in a direction away from the detection part 1 or the plug part 2, so that the end of the electrical connector 6 away from the detection part 1 or the plug part 2 is used to connect with the detection line of the detection device.

[0047] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, in some embodiments, the electrical connector 6 is detachably connected to the plug-in portion 2 or the detection portion 1.

Such a configuration enables the mounting plate 61 to be electrically connected to at least one of the plug-in portion 2 and the detection portion 1, so that the electrical connector 6 can be electrically connected to the tab of the battery 7 to be tested through the plug-in portion 2 and the detection portion 1, and the mounting plate 61 can be rotated relative to the plug-in portion 2 to adjust the direction of the connecting plate 62, so as to facilitate the connection of the detection line of the detection device with the connecting plate 62, and improve the convenience of the user in connecting the detection line with the connecting plate 62.

[0050] Specifically, the mounting plate 61 and the connecting plate 62 are in the same plane, the connecting plate 62 is connected to one side edge of the mounting plate 61, a through hole is set in the middle of the mounting plate 61 as a mounting through hole, the plug-in part 2 is passed through the mounting through hole, the inner wall of the mounting through hole is abutted against the outer side surface of the plug-in part 2, and the mounting plate 61 is electrically connected to the plug-in part 2 by welding.

[0051] Of course, it is also possible to choose that the cross-sectional area of ​​the detection part 1 is larger than the cross-sectional area of ​​the plug-in part 2, so that a step structure is formed at the connection between the detection part 1 and the plug-in part 2, and the plug-in part 2 is inserted into the installation hole, so that the mounting plate 61 abuts against the step structure, and the inner wall of the installation hole abuts against the outer side of the plug-in part 2, so that the mounting plate 61 abuts against the plug-in part 2 and the detection part 1 at the same time, so that the mounting plate 61 is electrically connected to the plug-in part 2 and the detection part 1.

[0052] Reference Figures 1 to 4 As shown, in some embodiments, an isolation tube 3 is provided in the receiving groove 11, and the isolation tube 3 extends along the extending direction of the receiving groove 11. The isolation tube 3 has a protective channel inside, and the detection line 4 is passed through the protective channel. In this way, the isolation tube 3 can prevent the detection line 4 from directly contacting the isolation tube 3 in the receiving groove 11, so that when the detection part 1 and the plug-in part 2 are vibrated, the isolation tube 3 can absorb part of the vibration to reduce the vibration transmitted to the detection line 4, so that the isolation tube 3 can protect the detection line 4.

[0053] Specifically, the isolation tube 3 can be selected as a cylindrical tube body, the isolation tube 3 can be selected as a metal tube, and of course the isolation tube 3 can also be selected as a plastic tube. The protective channel inside the isolation tube 3 runs through the isolation tube 3, so that after the isolation tube 3 is set in the receiving groove 11, the detection line 4 can pass through the isolation tube 3 and extend to the bottom of the receiving groove 11.

[0054] The above-mentioned isolation tube 3 can be selected to be completely located inside the receiving groove 11. Of course, the end of the isolation tube 3 facing away from the receiving groove 11 can also be selected to extend along the plug-in portion 2 toward the detection portion 1, so that the end of the isolation tube 3 facing away from the receiving groove 11 is located on the side of the detection portion 1 facing away from the plug-in portion 2, which makes it convenient for the staff to accurately insert the detection line 4 into the protective channel inside the isolation tube 3.

[0055] The size of the above-mentioned isolation tube 3 can be selected to match the size of the receiving groove 11, so that the outer wall of the isolation tube 3 abuts against the inner wall of the receiving groove 11 to clamp the isolation tube 3 in the receiving groove 11; of course, the outer side of the isolation tube 3 and the inner wall of the receiving groove 11 can also be connected by bonding to stably set the isolation tube 3 in the receiving groove 11.

[0056] Reference Figures 1 to 4 As shown, in some embodiments, the isolation tube 3 is fixedly connected in the receiving groove 11, and the detection line 4 is spaced apart from the inner wall of the protection channel. In this way, the detection line 4 is spaced apart from the inner wall of the protection channel in the protection channel, and when the isolation tube 3 rotates at any time when the plug-in part 2 and the detection part 1 rotate, the detection line 4 will not rotate with the isolation tube 3, thereby preventing the detection line 4 from being twisted and damaged when the plug-in part 2 and the detection part 1 rotate.

[0057] Specifically, the outer side surface of the isolation tube 3 is connected to the inner wall of the accommodating groove 11 by bonding. Of course, you can also choose to set a buckle on the inner wall of the accommodating groove 11, and set the isolation tube 3 in the buckle, so that the isolation tube 3 is fixedly connected in the accommodating groove 11, that is, when the plug-in part 2 and the detection part 1 are rotated to make the plug-in part 2 threadedly connected with the screw hole of the pole ear, the isolation tube 3 can rotate together with the accommodating groove 11.

[0058] The inner diameter of the isolation tube 3 is larger than the diameter of the detection wire 4, so that after the detection wire 4 is set in the isolation tube 3, the detection wire 4 can be spaced from the inner wall of the protection channel, so that when the isolation tube 3 rotates, the detection wire 4 will not be driven to rotate, thereby preventing the detection wire 4 from twisting and being damaged.

[0059] Reference Figures 1 to 4As shown, in some embodiments, the isolation tube 3 is spaced from the bottom of the receiving groove 11, and a protective sleeve 5 is provided between the bottom of the receiving groove 11 and the isolation tube 3. The protective sleeve 5 has a protective cavity inside, and the protective sleeve 5 is provided with an opening communicating with the protective cavity on the side facing the isolation tube 3, and the end of the detection line 4 is arranged in the protective cavity through the opening of the protective sleeve 5. In this arrangement, the detection line 4 passing through the isolation tube 3 can enter the protective cavity through the opening of the protective sleeve 5, so that the protective sleeve 5 protects the detection line 4 with a relatively fragile structure. When the detection part 1 and the plug-in part 2 vibrate, the protective sleeve 5 can absorb part of the vibration to prevent the end of the detection line 4 from colliding with the bottom of the receiving groove 11, ensuring that the detection line 4 can stably collect temperature information.

[0060] Specifically, one end of the isolation tube 3 close to the bottom of the receiving groove 11 is spaced apart from the bottom of the receiving groove 11, so that the protective sleeve 5 can be set on the bottom of the receiving groove 11. The protective sleeve 5 can be placed on the bottom of the receiving groove 11, so that the bottom of the receiving groove 11 and the isolation tube 3 form a limit for the protective sleeve 5. Of course, the protective sleeve 5 can also be bonded to the bottom of the receiving groove 11.

[0061] The above-mentioned protective cover 5 can be selected as a cylindrical structure. The interior of the protective cover 5 is hollow, so that the internal space of the protective cover 5 serves as a protective cavity. The protective cover 5 is provided with a through hole as an opening on the side facing the isolation tube 3, so that the detection line 4 passing through the isolation tube 3 is inserted into the protective cavity through the opening, so that the protective cover 5 can protect the end of the detection line 4; the end of the detection line 4 is used to collect temperature information, and its structure is relatively fragile. The protective cover 5 can cover the end of the detection line 4 to protect the end of the detection line 4; and the protective cover 5 can be made of copper or other materials with good thermal conductivity, so that the temperature of the bottom of the accommodating groove 11 is less dissipated during the process of being transferred to the protective cover 5, so that the protective cover 5 will not affect the temperature detection accuracy of the detection line 4.

[0062] Reference Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, a limiting ring 31 is provided in the isolation tube 3, the limiting ring 31 is coaxially arranged with the isolation tube 3, the limiting ring 31 is slidably connected with the inner wall of the protection channel, so that the limiting ring 31 can rotate along the circumferential direction of the isolation tube 3, and the detection line 4 is passed through the limiting ring 31, and the detection line 4 is connected to the inner side of the limiting ring 31. In this way, the detection line 4 is converged by the limiting ring 31, and the limiting ring 31 limits the movement of the detection line 4 along the radial direction of the isolation tube 3 in the protection channel, and when the isolation tube 3 rotates with the plug-in part 2 and the detection part 1, the limiting ring 31 can rotate relative to the isolation tube 3 and the detection line 4 does not rotate, so as to avoid the detection line 4 from being twisted and damaged.

[0063] Specifically, the limiting ring 31 can be selected to be an annular structure, the cross-section of the protection channel is circular, and an annular groove is set on the inner wall of the protection channel. The axial centerline of the annular groove coincides with the axial centerline of the limiting ring 31, and the outer edge of the limiting ring 31 is inserted into the annular groove, so that the limiting ring 31 can slide along the circumference of the annular groove, that is, the limiting ring 31 can rotate in the protection channel along the circumference of the isolation tube 3; of course, it is also possible to choose to set a bearing on the inner wall of the protection channel, the bearing having an inner ring and an outer ring that can rotate relative to each other, the outer ring is sleeved on the outside of the inner ring, the outer ring is connected to the inner wall of the protection channel, and the limiting ring 31 is set inside the inner ring.

[0064] The detection line 4 is inserted into the limiting ring 31. The inner diameter of the limiting ring 31 can be selected to be equal to the diameter of the detection line 4, so that the surface of the detection line 4 abuts against the inner side of the limiting ring 31, and the relative position of the detection line 4 and the limiting ring 31 is kept stable by friction; of course, glue can also be used to bond the inner side of the limiting ring 31 to the detection line 4. When the isolation tube 3 rotates with the plug-in part 2 and the detection part 1, the limiting ring 31 can rotate relative to the isolation tube 3 without rotating the detection line 4, thereby preventing the detection line 4 from being twisted and damaged.

[0065] Reference Figure 3 and Figure 4 As shown, in some embodiments, the limiting ring 31 is located at one end of the isolation tube 3 away from the bottom of the receiving groove 11. This arrangement facilitates the user to pass the detection line 4 through the limiting ring 31 when the detection line 4 passes through the isolation tube 3, and also facilitates the operation of connecting the detection line 4 with the limiting ring 31 after passing through the limiting ring 31.

[0066] Specifically, the limiting ring 31 is at one end of the isolation tube 3 away from the bottom of the accommodating groove 11, so that the limiting ring 31 is located at the port of the isolation tube 3. When the user passes the detection line 4 through the isolation tube 3, the detection line 4 can be first passed through the limiting ring 31 to avoid the difficulty in aligning the detection line 4 with the inside of the limiting ring 31 in the isolation tube 3, and it is also convenient for the operation of connecting the detection line 4 with the limiting ring 31 after passing through the limiting ring 31.

[0067] Reference Figure 1 and Figure 2 As shown, in some embodiments, one end of the isolation tube 3 away from the bottom of the receiving groove 11 extends to the side of the detection part 1 facing away from the plug-in part 2. This arrangement facilitates the user to accurately insert the detection line 4 into the protection channel, and avoids the detection line 4 colliding with the end of the isolation tube 3 when the detection line 4 is inserted into the protection channel.

[0068] Specifically, one end of the isolation tube 3 away from the bottom of the receiving groove 11 protrudes from the side of the detection part 1 facing away from the plug-in part 2, that is, the end of the isolation tube 3 away from the bottom of the receiving groove 11 extends to the outside of the notch of the receiving groove 11.

[0069] Reference Figure 1 and Figure 2 As shown, in some embodiments, along the direction from the detection part 1 to the plug part 2, the projection area of ​​the detection part 1 is larger than the projection area of ​​the plug part 2. With such a configuration, when the plug part 2 is inserted into the process hole 71, the detection part 1 can abut against the area around the process hole 71, thereby improving the stability of the battery test connector connected to the battery to be tested 7, and facilitating the user to grasp the detection part 1 and rotate it to drive the plug part 2 to rotate.

[0070] Specifically, when the detection part 1 and the connecting part 2 are both cylindrical structures, in the radial direction of the connecting part 2 and the detection part 1, the diameter of the detection part 1 is larger than the diameter of the connecting part 2, so that the projected area of ​​the detection part 1 is larger than the projected area of ​​the connecting part 2. Of course, as long as the size of the detection part 1 in the radial direction of the connecting part 2 is larger than the size of the connecting part 2, it will be sufficient.

[0071] When the battery test connector provided by the embodiment of the present disclosure is used, the bolts on the battery 7 to be tested are removed, the detection line 4 is passed through the limit ring 31 and inserted into the isolation tube 3, so that the end of the detection line 4 can be located in the protective cover 5, the plug-in part 2 is passed through the process hole 71 of the battery 7 to be tested and aligned with the screw hole of the pole ear in the battery 7 to be tested, and the detection part 1 is rotated to drive the plug-in part 2 to rotate, so that the plug-in part 2 is threadedly connected with the screw hole of the pole ear in the battery 7 to be tested; during the rotation of the detection part 1 and the plug-in part 2, the limit ring 31 rotates relative to the isolation tube 3, so that the detection line 4 does not rotate. The end of the detection line 4 is located in the protective cavity of the protective cover 5 and is located inside the battery 7 to be tested near the pole ear.

[0072] The detection line of the detection device is connected to the connecting plate 62 of the electrical connector 6, so that the detection device is electrically connected to the pole ear of the battery to be tested 7 through the plug-in part 2 and the detection part 1. The detection device performs charging and discharging detection on the battery to be tested 7. The detection line 4 collects the temperature changes of the pole ear during the charging and discharging process of the battery to be tested 7, so that the temperature measuring device can monitor the internal temperature of the battery to be tested 7.
