Description

Technical Field

[0001] This application relates to the technical field of server testing, and particularly to a testing device, method and medium for a server button battery. Background Art

[0002] In the related art, when testing a button battery for a server with a simple architecture, generally, a tweezer is used to short-circuit the diode of the battery circuit or other components, and a multimeter is used to cooperate for the battery fault test; for the reverse charging test of the battery, the battery is directly forced to be pressed into the battery base in the reverse direction for testing, which is extremely likely to damage the battery base. For a server with a complex architecture, when testing a button battery, generally, components are short-circuited by soldering wires and the multimeter is connected to the circuit by soldering wires for testing. However, the method of using a tweezer and a multimeter for testing cannot test the button battery of a server with a complex architecture, and is easy to damage the button battery base; while using the method of soldering wires to test a server with a complex architecture is not only time-consuming and laborious, but also easy to cause a short circuit of the main board or inaccurate testing due to insecure soldering.

[0003] In view of this, how to provide a testing device, method and medium for a server button battery with a wide application range, simple and easy testing and high testing accuracy has become a problem to be solved by those skilled in the art. Summary of the Invention

[0004] This application provides a testing device, method and computer-readable storage medium for a server button battery, so as to at least solve the problems of poor generality, complex testing and low accuracy in the related art.

[0005] This application provides a testing device for a server button battery, including: a temperature collector, a battery test seat connected to the temperature collector, a test path selection and gating module connected to the battery test seat, and a power supply connected to the test path selection and gating module; wherein: The battery test seat is used to place the button battery to be tested. The test path selection and gating module is used to determine a test path corresponding to the test item according to different test items, so that the power supply supplies power to the button battery to be tested on the battery test seat through the test path. The temperature collector is used to collect the temperature data of the button battery to be tested during the test of the button battery to be tested.

[0006] This application also provides a testing method for a server button battery, which is applied to the testing device for a server button battery as described above, and includes: After the button battery to be tested is placed on the battery test seat according to the test item requirements corresponding to the current test item, control the test path corresponding to the current test item to be conducted. When the test duration of the current test item lasts for a preset duration, determine whether there is any leakage or explosion in the button cell under test; When there is no leakage or explosion, determine whether the temperature curve formed by the temperature data corresponding to the current test item is within the preset limit. If it is within the preset limit, determine that the current test item passes the test; If there is any leakage or explosion, or the temperature curve is not within the preset limit, determine that the button cell under test fails the test; When the current test item passes, take the next test item as the current test item, and return to execute the step of controlling the conduction of the test path corresponding to the current test item after placing the button cell under test on the battery test seat according to the requirements of the test item corresponding to the current test item, until the last test item is completed; When each test item passes the test, determine that the button cell under test passes the test successfully.

[0007] The present application also provides a computer-readable storage medium, in which a computer program is stored. When the computer program is executed by a processor, the steps of the test method for the server button cell as described above are implemented.

[0008] It can be seen from the above technical solutions that the beneficial effects of the present invention are as follows: When testing the button cell under test through the test device for the server button cell, the button cell under test can be placed through the battery test seat, and the test path selection module can determine the test path corresponding to the test item according to different test items, so that the power supply supplies power to the button cell under test on the battery test seat through the test path to test the button cell under test for the test item. Different test paths can be selected for different test items to implement the test for different test items, and during the test process of each test item, the temperature data of the button cell under test can be collected through the temperature collector, so as to determine the test result of the button cell under test for the test item in combination with the external situation of the button cell under test after the test is completed. The present application provides a general test device for server button cells. No matter which server it is, the button cell can be placed on the test device to perform the tests for each test item, without damaging the button cell base on the server.

Detailed implementation manners

[0012] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present application.

[0013] It should be noted that in the description of the present application, the terms "include", "comprise" or any other variation thereof are intended to cover a non-exclusive inclusion, such that a process, method, article or device including a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. The terms "first", "second", etc. in the present application are used to distinguish similar objects and are not used to describe a specific order or sequence.

[0014] It should be noted that RTC (Real Time Clock) refers to the clock installed on electronic devices or integrated circuits. In the design of server motherboards, the role of RTC is to ensure the accuracy of the system time and the integrity of BIOS (Basic Input Output System) settings when the motherboard is powered off. When the server is powered on, the CPU (Central Processing Unit) itself has timer and clock functions, and at this time, the RTC is not required to display the time and adjust the timing. When the server is powered off, the RTC is needed to provide the clock function. The RTC has a power supply separated from the system power supply, which is generally a lithium manganese button battery. In server-class devices, if the motherboard contains components such as button batteries that pose risks of chemical corrosion and explosion, corresponding fault tests should be carried out in accordance with relevant regulations to ensure the safety of the device during use. The safety regulations tests mainly related to button batteries include: 1. Overcharging of the battery, that is, simulating the charging phenomenon under any single fault condition that may occur in the charging circuit and cause overcharging of the battery. 2. Overdischarging of the battery, simulating the rapid discharge of the battery when the current-limiting or voltage-limiting components in the battery load circuit are open or short-circuited. 3. Accidental charging of the battery, simulating the accidental charging phenomenon that may occur in the circuit due to component failures. 4. Reverse charging of the battery, simulating the phenomenon of reverse charging of the battery when a circuit fault occurs. During the above several fault simulation experiments, the tested battery shall not show phenomena such as chemical leakage caused by the rupture of the battery case, battery explosion, and the surface temperature of the battery exceeding the specification limits. In the development stage of the server, it is essential to carry out safety regulations design and verification tests on the server.

[0015] As the market's requirements for server performance increase day by day, the design of server systems has become increasingly complex. For servers with a simple architecture (such as 1U and 2U servers), when conducting a button battery test, simply opening the server upper cover can ensure observing the position of the button battery in the power-on state of the motherboard, and tools such as tweezers can be used to short-circuit the diodes or other components on the battery circuit to simulate fault conditions, and then a multimeter can be used to obtain information such as voltage and current to determine whether the test passes. However, for complex AI (Artificial Intelligence) or multi-node servers, in the system architecture design, a single node must be connected to the system power supply module to power on the motherboard, and the node structure design is generally very compact. When the node is connected to the system power supply module, it is impossible to short-circuit the components and connect the multimeter according to the above method, so this test cannot be carried out. In the related art, for servers with a complex architecture, generally, the method of soldering wires is used to short-circuit the components and connect the multimeter to the circuit through soldering wires, which is likely to cause a short circuit of the motherboard, or the soldering is not firm resulting in inaccurate testing, and the method of using soldering wires is also time-consuming and laborious.

[0016] In view of this, the present application provides a test device for a server button battery with strong test versatility, simple test and high accuracy. To enable those skilled in the art of this technology to better understand the solution of the present application, the following further detailed description of the present application will be given in conjunction with the accompanying drawings and specific embodiments.

[0017] Please refer to Figure 1 the structural schematic diagram of a test device for a server button battery shown below, and a detailed description of the device will be given. The test device for the server button battery includes: a temperature collector 1, a battery test socket 2 connected to the temperature collector 1, a test path selection and gating module 3 connected to the battery test socket 2, and a power supply 4 connected to the test path selection and gating module 3; wherein: The battery test socket 2 is used to place the button battery to be tested; The test path selection and gating module 3 is used to determine the test path corresponding to the test item according to different test items, so that the power supply 4 supplies power to the button battery to be tested on the battery test socket 2 through the test path; The temperature collector 1 is used to collect the temperature data of the button battery to be tested during the test of the button battery to be tested.

[0018] It should be noted that in the embodiments of the present application, the button cell to be tested can be placed on the battery test base 2 according to the requirements of the test items. When testing the button cell to be tested, the test path selection and gating module 3 can determine the test path corresponding to the test item according to different test items, and control the conduction of the test path, so that the power supply 4 can supply power to the button cell to be tested on the battery test base 2 through the test path, realizing the test of the test item. And during the test of the button cell to be tested, the temperature collector 1 collects the temperature data of the button cell to be tested, so that after the test of the test item is completed, the test result of the button cell to be tested in the test item can be determined according to the external situation of the button cell to be tested combined with the temperature data.

[0019] In one embodiment, as Figure 2 shown, in this embodiment, in order to test the button cell to be tested more conveniently and accurately, the battery test base 2 may include a first button cell base 21 and a second button cell base 22; The test path selection and gating module 3 may include a first controllable switch 31, a second controllable switch 32, a third controllable switch 33, a fourth controllable switch 34, a diode 35 and a variable resistor 36; wherein: The first end of the first button cell base 21 is connected to the first end of the first controllable switch 31. The second end of the first button cell base 21, the second end of the second button cell base 22, the anode of the diode 35 and the first end of the third controllable switch 33 are connected to each other. The first end of the second controllable switch 32 is connected to the first end of the second button cell base 22. The second end of the first controllable switch 31, the second end of the second controllable switch 32, the second end of the variable resistor 36 and the positive pole of the power supply 4 are connected to each other. The first end of the variable resistor 36, the cathode of the diode 35, the second end of the third controllable switch 33 and the negative pole of the power supply 4 are connected to each other. The first end of the temperature collector 1 is connected to the third end of the first button cell base 21, and the second end of the temperature collector 1 is connected to the third end of the second button cell base 22.

[0020] It can be understood that there may be two battery test sockets 2 in the embodiments of the present application. One is the first button battery base 21, and the other is the second button battery base 22. The positive and negative electrode wirings of the first button battery base 21 and the second button battery base 22 are opposite. That is, when the first end of the first button battery base 21 is the positive electrode and the second end is the negative electrode, the first end of the second button battery base 22 is the negative electrode and the second end is the positive electrode; when the first end of the first button battery base 21 is the negative electrode and the second end is the positive electrode, the first end of the second button battery base 22 is the positive electrode and the second end is the negative electrode. Thus, when performing different item tests on the button battery to be tested, the button battery to be tested can be placed on the first button battery base 21 or on the second button battery base 22 according to actual needs. In addition, the temperature collector 1 in the present application can be respectively connected to the first button battery base 21 through the first thermocouple and to the second button battery base 22 through the second thermocouple, so as to collect the temperature data on the surface of the button battery to be tested in real time.

[0021] It should also be noted that in the present application, for different test items, such as each test item being a battery overcharge test, a battery overdischarge test, a battery accidental charge test, and a battery reverse charge test, the corresponding test path can be selected to conduct by controlling the on / off of the first controllable switch 31, the second controllable switch 32, the third controllable switch 33, and the fourth controllable switch 34. And after the corresponding test path is conducted, the charging voltage of the button battery to be tested can be adjusted by adjusting the resistance value of the variable resistor 36 to implement the test of each test item.

[0022] Among them, the model of the diode in this embodiment can be the same as the model of the diode used when the button battery on the server motherboard works normally. Among them, the principle circuit diagram of the normal operation of the button battery on the server motherboard is as Figure 3 shown, and the model of the diode can be BAS70.

[0023] In one implementation manner, when the test item is a battery overcharge test, the first button battery base 21 is used to place the button battery to be tested, and the test path is the path formed by closing the first controllable switch 31, the third controllable switch 33, and the fourth controllable switch 34 and opening the second controllable switch 32; When the test item is a battery overdischarge test, the first button battery base 21 is used to place the button battery to be tested, and the test path is the path formed by closing the first controllable switch 31 and opening the second controllable switch 32, the third controllable switch 33, and the fourth controllable switch 34; When the test item is a battery accidental charging test, the first button battery base 21 is used to place the button battery to be tested, and the test path is a path formed by closing the first controllable switch 31, the third controllable switch 33 and the fourth controllable switch 34 and disconnecting the second controllable switch 32; When the test item is a battery reverse charging test, the second button battery base 22 is used to place the button battery to be tested in reverse, and the test path is a path formed by the first controllable switch 31 being disconnected and the second controllable switch 32, the third controllable switch 33 and the fourth controllable switch 34 being closed.

[0024] It can be understood that in order to more accurately implement the testing of various test items of the button battery to be tested in the embodiment of the present application, the battery overcharge test, the battery over-discharge test and the battery accidental charging test can be performed. Since the battery to be tested needs to be placed in the forward direction, when the button battery to be tested is tested for these three test items, the button battery to be tested can be placed on the first button battery base 21 in a forward connection manner, so that the battery overcharge test, the battery over-discharge test and the battery accidental charging test of the button battery to be tested can be respectively implemented by controlling the on and off of the controllable switches that are not connected among the first controllable switch 31, the second controllable switch 32, the third controllable switch 33 and the fourth controllable switch 34. Of course, since the positive and negative poles of the second button battery base 22 are opposite to those of the first button battery base 21, when it is necessary to perform a battery reverse charging test on the button battery to be tested, the button battery to be tested can be placed positively connected on the second button battery base 22, and the battery reverse charging test of the button battery to be tested can be achieved by controlling the on and off of the controllable switches that are not turned on among the first controllable switch 31, the second controllable switch 32, the third controllable switch 33, and the fourth controllable switch 34.

[0025] In practical applications, the first end of the first button cell base 21 is the positive electrode and the second end is the negative electrode. The first end of the second button cell base 22 is the negative electrode and the second end is the positive electrode. When testing the button cell under test for the battery overcharging test item, the button cell under test can be placed in the first button cell base 21 in a positive connection manner, and the first controllable switch 31, the third controllable switch 33, and the fourth controllable switch 34 are controlled to be closed, and the second controllable switch 32 is controlled to be open, thereby forming a test path. Among them, the diode 35 is short-circuited. By adjusting the variable resistor 36 (such as a sliding rheostat), the charging voltage value of the button cell under test can be changed until the charging voltage value exceeds the specification of the button cell under test and lasts for a preset duration, so as to simulate battery overcharging and realize the test of battery overcharging. During the test, the temperature data on the surface of the button cell under test is collected in real time by the temperature collector 1. After the test is completed, the surface condition of the button cell under test can be observed, and by analyzing the temperature data, it can be determined whether the test item passes. Among them, in the embodiment of the present application, in order to improve the accuracy of adjusting the charging voltage value of the button cell under test, the power supply 4 can adopt an adjustable power supply. Therefore, by adjusting the adjustable power supply and the variable resistor 36, the charging voltage value of the button cell under test can be quickly and accurately adjusted.

[0026] When testing the button cell under test for the battery overdischarging test item, the button cell under test is still placed in the first button cell base 21 in a positive connection manner, and the first controllable switch 31 is controlled to be closed, and the second controllable switch 32, the third controllable switch 33, and the fourth controllable switch 34 are controlled to be open, thereby forming a corresponding test path. There are no current-limiting or voltage-limiting components in the formed test path, so that the rapid discharge test of the battery can be simulated and the test lasts for a preset duration. During the test, the temperature data on the surface of the button cell under test can be collected in real time by the temperature collector 1. After the test is completed, the surface condition of the button cell under test can be observed, and by analyzing the temperature data, it can be determined whether the test item passes.

[0027] When conducting the test item of accidental battery charging test on the button battery under test, the button battery under test is still placed in the first button battery base 21 in the positive connection mode, and the first controllable switch 31, the third controllable switch 33 and the fourth controllable switch 34 are controlled to be closed, and the second controllable switch 32 is controlled to be open, so as to form a corresponding test path. Moreover, the variable resistor 36 and the adjustable power supply can be adjusted to make the charging voltage of the button battery under test consistent with the normal working voltage of the server main board (such as 3.3V), so as to simulate the phenomenon that the system power charges the battery when there is a line fault in the relevant part of the server, realize the accidental charging test of the button battery under test, and the temperature data on the surface of the button battery under test can be collected in real time through the temperature collector 1 during the test. After the test is completed, the surface condition of the button battery under test can be observed, and the temperature data can be analyzed to determine whether the test item passes.

[0028] When conducting the project test of reverse battery charging test on the button battery under test, the button battery under test is placed in the second button battery base 22 in the positive connection mode. Since the positive and negative poles of the first button battery base 21 and the second button battery base 22 are reversed, the button battery under test placed in the second button battery base 22 is reversed compared with that placed in the first button battery base 21. The first controllable switch 31 is controlled to be open, the second controllable switch 32, the third controllable switch 33 and the fourth controllable switch 34 are controlled to be closed, so as to form a corresponding test path. By adjusting the variable resistor 36 and the adjustable power supply, the battery charging voltage is made consistent with the normal working voltage of the server main board (such as 3.3V), so as to simulate the accidental charging of the server main board battery in the case of reverse connection of the positive and negative poles, realize the reverse charging test of the button battery under test. The test can last for a preset duration, and the temperature data on the surface of the button battery under test can be collected in real time through the temperature collector 1 during the test. After the test is completed, the surface condition of the button battery under test can be observed, and the temperature data can be analyzed to determine whether the test item passes.

[0029] It should be noted that in practical applications, the preset duration can be 7 hours, that is, each test item is tested for 7 hours. And after each test item is completed, it can be observed whether there are cracks, leakage or explosion on the surface of the button battery to be tested. If at least one of these situations occurs, it is determined that the test item fails and the button battery to be tested fails the test. If there are no cracks, leakage or explosion, the temperature data obtained during the test process of this test item can be further used to establish a temperature curve, and it is identified whether the temperature curve is within the preset limit. If there are data points not within the preset limit, it is determined that the button battery to be tested fails the test. If after each test item is completed, there are no cracks, leakage or explosion on the button battery to be tested, and the corresponding temperature curve is within the preset limit, it means that the button battery to be tested passes the test.

[0030] In one embodiment, in order to ensure the safety of the circuit, a voltage-dividing resistor 5 can also be set. Among them, the first end of the voltage-dividing resistor 5 is connected to the first end of the variable resistor, and the second end of the voltage-dividing resistor 5 is connected to the negative electrode of the power supply 4.

[0031] In one embodiment, as Figure 4 shown, the device further includes a processor 6, and the processor 6 is connected to the control ends of the first controllable switch 31, the second controllable switch 32, the third controllable switch 33, and the fourth controllable switch 34; The processor 6 is configured to control the first controllable switch 31, the third controllable switch 33, and the fourth controllable switch 34 to be closed and control the second controllable switch 32 to be opened when receiving a first instruction corresponding to the battery overcharge test; control the first controllable switch 31 to be closed and control the second controllable switch 32, the third controllable switch 33, and the fourth controllable switch 34 to be opened when receiving a second instruction corresponding to the battery overdischarge test; control the first controllable switch 31, the third controllable switch 33, and the fourth controllable switch 34 to be closed and control the second controllable switch 32 to be opened when receiving a third instruction corresponding to the battery accidental charge test; control the first controllable switch 31 to be opened and control the second controllable switch 32, the third controllable switch 33, and the fourth controllable switch 34 to be closed when receiving a fourth instruction corresponding to the battery reverse charge test.

[0032] It should be noted that in this embodiment, in order to improve the test efficiency and test automation, the processor 6 can control the closing and opening of each controllable switch according to the test items. Among them, instructions corresponding to each test item one by one, and the switch conduction conditions of the test paths corresponding to each test item can be preset in advance. Thus, the processor 6 can determine the corresponding test item according to the received instruction, and control the conduction of the corresponding switch according to the switch conduction condition of the test path corresponding to the test item, so as to realize the tests of different test items of the button battery to be tested, thereby improving the test efficiency.

[0033] In addition, for each test item, the test order of each test item can be determined in advance. When detecting the start test instruction, the processor 6 controls the conduction of the corresponding controllable switches according to the switch conduction condition of the current test item for the current test item, and detects whether the test time of the test item reaches the preset duration. If it reaches the preset duration, the corresponding switch is disconnected to make the test path disconnected. And after disconnecting for the second preset duration, after the surface temperature of the button battery to be tested returns to normal temperature, then control the conduction of the corresponding switch according to the switch conduction condition of the test path corresponding to the next test item, so as to start the test of the next test item. In addition, the test items corresponding to the first button battery base can be arranged in the front, and the test items corresponding to the second button battery can be arranged in the back. Thus, after the test items located on the first button battery base are tested, a prompt to switch the placement position of the button battery can be issued. And when it is detected that there is a button battery to be tested correctly installed on the second button battery base, control the conduction of the corresponding switch according to the test path of the corresponding test item to perform the test of the corresponding test item, so as to better improve the test efficiency and automation.

[0034] In one implementation manner, the processor 6 can also be used to connect to the temperature collector 1; The temperature collector 1 is further used to generate a temperature curve based on the collected temperature data; The processor 6 is further used to determine that the test fails when there are data points in the temperature curve that are not within the preset limits.

[0035] It should be noted that in this embodiment, the processor 6 can be connected to the temperature collector 1, obtain the temperature data collected by the temperature collector 1, perform curve fitting on these temperature data to obtain a temperature curve, and then determine whether the temperature curve is within the preset limit. If it is not within the preset limit, it means that the corresponding test item test fails. If it is within the preset limit and there are no cracks, leakage, or explosion on the surface of the button battery to be tested, it is determined that the test item of the button battery to be tested passes.

[0036] That is to say, in the case where the server needs to perform safety regulations tests, due to architectural and structural limitations, the button battery on the motherboard cannot be tested for faults in the powered-on state. After determining whether the circuit of the server button battery is consistent with the test device provided in this application according to the schematic diagram, the button battery can be removed and placed in the test device, and the safety regulations test can be performed and the test result can be output according to the test process described in this application (such as Figure 5 shown).

[0037] It can be seen that when testing the button battery to be tested through the test device for the server button battery, the button battery to be tested can be placed through the battery test socket, and the test path selection module can determine the test path corresponding to the test item according to different test items, so that the power supply supplies power to the button battery to be tested on the battery test socket through this test path, so as to test the button battery to be tested for this test item. Different test paths can be selected for different test items to achieve the test of different test items, and during the test process of each test item, the temperature data of the button battery to be tested can be collected through the temperature collector, so as to determine the test result of the button battery to be tested for this test item in combination with the external situation of the button battery to be tested after the test is completed. This application provides a general test device for server button batteries. No matter which server it is, the button battery can be placed on this test device to perform tests for each test item, and the button battery base on the server will not be damaged. The test is simple and easy to perform, and the test accuracy is high.

[0038] Based on the above embodiments, in combination with the test device for the server button battery, the corresponding test method for the server button battery will be described here. Such as Figure 5 shown, this embodiment provides a test method for a server button battery, which is applied to the test device for a server button battery as described above. The method includes the following S110 to S170.

[0039] S110: After the button battery to be tested is placed on the battery test socket according to the test item requirements corresponding to the current test item, control the conduction of the test path corresponding to the current test item.

[0040] It should be noted that for each test item, in this embodiment, one test item is taken as an example for detailed description. Different test items correspond to different test paths. Therefore, the corresponding test path can be controlled to conduct according to the current test item, so as to perform the test of the current test item.

[0041] S120: When the test duration of the current test item lasts for a preset duration, determine whether there are cracks, leakage or explosion phenomena in the button battery to be tested.

[0042] It is understandable that the test duration of each test item needs to reach the preset duration. When the preset duration is reached, it can be further determined whether there are cracks, leakage or explosion on the surface of the button battery to be tested, so as to determine the safety of the button battery to be tested.

[0043] S130: In the case of no cracks, leakage and explosion, determine whether the temperature curve formed by the temperature data corresponding to the current test item is within the preset limit. If it is within the preset limit, proceed to S140.

[0044] S140: Determine that the current test item passes the test.

[0045] That is to say, if there are no cracks, leakage and explosion, the temperature curve can be further formulated according to the temperature data collected during the current test item, and it is identified whether the temperature curve is within the preset limit. If the temperature curve is within the preset limit, it can be determined that the button battery to be tested passes the test of the current test item.

[0046] S150: If there are cracks, leakage or explosion, or the temperature curve is not within the preset limit, determine that the button battery to be tested fails the test.

[0047] If after the test, it is found that there are cracks, leakage or explosion in the button battery to be tested, it means that the button battery to be tested fails the test. Of course, if there are no cracks, leakage and explosion in the button battery to be tested, but the temperature curve is not within the preset limit, it is still determined that the button battery to be tested fails the test.

[0048] S160: When the current test item passes, take the next test item as the current test item and return to execute S110. After the button battery to be tested is placed in the battery test seat according to the requirements of the test item corresponding to the current test item, control the conduction of the test path corresponding to the current test item until the last test item is completed.

[0049] S170: When each test item passes the test, determine that the button battery to be tested passes the test.

[0050] It should be noted that after the test item is executed according to the above steps and it is determined that the test item passes, continue to execute the test of the next test item. If there is one test item that fails, it can be directly determined that the button battery to be tested fails the test. If all test items pass, it can be determined that the button battery to be tested passes the test, that is, the test passes.
