The various embodiments are described in a progressive manner herein, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other. As for the structures, products, etc. disclosed in the embodiments, since they correspond to the parts disclosed in the embodiments, the description is relatively simple, and the relevant parts can be referred to the description of the method part.

[0037] like Figure 1 As shown, Figure 1 A flowchart of a battery detection method provided in the present application. The battery detection method provided in the present application can be performed by a battery detection device, and the battery detection device includes a voltage measurement module for measuring voltage. For example, the voltage measurement module can be a multimeter, and the multimeter includes two detection contacts. The voltage measurement module determines the detected voltage based on the potential difference between the two detection contacts. It can be understood that the specific type of the voltage measurement module can be selected according to actual needs and is not specifically limited in this application. The battery detection method provided in the present application includes:

[0038] Step 101 : collecting a current voltage value detected by a voltage measurement module, where the current voltage value is obtained by collecting a voltage value between a positive electrode and a negative electrode of a battery to be measured by the voltage measurement module.

[0039] Before the battery to be measured is connected to the load, the battery detection equipment needs to measure and collect the voltage value between the positive and negative electrodes of the battery to be measured through the voltage measurement module to obtain the current voltage value of the battery to be measured, that is, the terminal voltage of the battery to be measured in an open circuit state with no current flowing.

[0040] Step 102: When the current voltage value satisfies the preset precondition, the working voltage value detected by the voltage measurement module is collected. The working voltage value is obtained by collecting the voltage value between the positive and negative electrodes of the battery to be measured through the voltage measurement module when the positive and negative electrodes of the battery to be measured are connected to the load and the load is started.

[0041] For the current voltage value of the battery to be measured that is collected, the battery detection equipment needs to determine whether the current voltage value meets the preset precondition, where the preset precondition is a precondition set in advance. If the preset precondition is met, the battery to be measured can be further tested. Exemplarily, the preset precondition can be set to the current voltage value reaching the minimum voltage value that can drive the load to start, where the minimum voltage value can be set according to the rated voltage value of the load, and the minimum voltage value required for the normal operation of the load must be greater than or equal to its rated voltage value. Exemplarily, if the load is the motherboard and display screen of a portable mobile device, its rated voltage value is 3.6V, so the minimum voltage value can be set to 3.6V. If the current voltage value of the battery to be measured reaches 3.6V, it is determined that the current voltage value meets the preset precondition.

[0042] If the battery detection device determines that the current voltage value of the battery to be measured meets the preset precondition, the battery detection device needs to further collect the working voltage value of the battery to be measured. Before collecting the working voltage value, it is necessary to connect the positive and negative electrodes of the battery to be measured to the load and start the load, and then collect the potential difference between the positive and negative electrodes of the battery to be measured through the voltage measurement module to obtain the working voltage value, where the working voltage value is determined by the open circuit voltage of the battery to be measured minus the internal resistance voltage drop. The larger the internal resistance voltage drop, the smaller the working voltage value.

[0043] It should also be noted that when the positive and negative electrodes of the battery to be measured are connected to the load, the voltage measurement module may not be able to directly connect to the positive and negative electrodes of the battery to be measured. At this time, the working voltage value can be collected by setting the positive test point and the negative test point on the load. The positive test point and the negative test point are specific contact positions for connecting test equipment or detecting battery performance. The positive test point is a detection interface for connecting the positive electrode of the battery to be measured, corresponding to the positive electrode of the battery to be measured, and is used to measure voltage, current or perform functional tests. The negative test point is a detection interface for connecting the negative electrode of the battery to be measured. The negative test point corresponds to the negative electrode of the battery to be measured, and is used to form a complete test loop. Exemplarily, the load can be a mainboard and a display screen. The battery to be measured is installed on the mainboard to power the mainboard and the display screen, so that the mainboard and the display screen can work normally. The positive test point and the negative test point are provided in the battery mother seat of the mainboard. The two detection contacts of the battery measurement module can collect the working voltage of the battery to be measured by connecting to the positive test point and the negative test point respectively.

[0044] In one implementation, when the current voltage value does not satisfy the preset precondition, the battery to be measured is charged until it is detected that the current voltage value satisfies the preset precondition.

[0045] If the current voltage value of the battery to be measured cannot reach the minimum voltage value for starting the load, the battery detection device needs to charge the battery to be measured until the voltage measurement module detects that the current voltage value of the battery to be measured reaches the minimum voltage value that can start the load, and then stops charging. For example, the battery detection device also includes a charging module for charging the battery. When the battery detection device determines that the current voltage value of the battery to be measured is less than the minimum voltage value, the charging module is controlled to connect to the positive and negative electrodes of the battery to be measured to charge the battery to be measured. After detecting that the current voltage value of the battery to be measured reaches the minimum voltage value or charging is completed, the charging module is controlled to disconnect from the positive and negative electrodes of the battery to be measured. After the battery to be measured is subsequently connected to the load, the working voltage value of the battery to be measured is collected. The specific process can refer to the technical solution described above, and will not be repeated here.

[0046] Step 103: Determine the health status of the battery to be measured according to the fluctuation of the detected operating voltage value.

[0047] After collecting the working voltage value, the battery detection equipment needs to determine the health status of the battery to be measured based on the fluctuation of the detected working voltage value. It should be noted that when the internal resistance of the battery is low, the voltage drop of the battery is small when the load is working. If the internal resistance increases due to aging or the shedding of active substances, the voltage drop will increase significantly under the same current, which is manifested as the voltage fluctuation of the battery when the load is working. For example, when the internal resistance of a lithium battery increases, the voltage may drop sharply and decay rapidly at the beginning of discharge, reflecting its decreased energy storage capacity. In addition, battery aging will lead to increased polarization on the electrode surface, and uneven charge distribution will cause additional voltage fluctuations, especially when switching between charge and discharge. Therefore, in this application, the health status of the battery to be measured can be determined by analyzing the fluctuation of the working voltage value. In one embodiment, step 103 determines the health status of the battery to be measured based on the fluctuation of the detected working voltage value, including:

[0048] Step 1031: Determine whether the working voltage value detected within a preset time period is stable.

[0049] Step 1032: When the operating voltage value is stable, determine that the health state of the battery to be measured is healthy.

[0050] Step 1033: When the operating voltage value is unstable, determine that the health state of the battery to be measured is unhealthy.

[0051] Specifically, the battery detection device can determine whether the working voltage value detected by the voltage measurement module is stable within a preset time length, wherein the preset time length can be set according to actual needs, for example, set to 5 seconds, 30 seconds or 1 minute, etc., which is not specifically limited in this application. If the working voltage value of the battery to be measured is stable (including slight fluctuations) within the preset time length, the health state of the battery to be measured can be determined to be healthy. If the working voltage value of the battery to be measured is unstable within the preset time length and has large fluctuations, the health state of the battery to be measured can be determined to be unhealthy. Exemplarily, the battery detection device can regard the situation where the voltage change amplitude of the working voltage value is ≤ 1% of the rated voltage (such as a 48V battery pack allows ±0.48V fluctuations) as a stable working voltage value, and the situation where the voltage change amplitude of the working voltage value is ≥ 5% of the rated voltage as an unstable working voltage value, and determine the health state of the battery to be measured according to the stability of the working voltage value within the preset time length. Alternatively, the battery detection device can determine the standard deviation of the working voltage value within the preset time length. If the standard deviation is less than the standard deviation threshold, the health state of the battery is marked as healthy, otherwise the health state of the battery is marked as unhealthy. For example, Figure 2 As shown, Figure 2 A schematic diagram of determining the health status of a battery to be measured is provided in this application.

[0052] In one embodiment, after determining that the health state of the battery to be measured is unhealthy, the method further includes:

[0053] Step 104: Determine the cause of the failure of the battery to be measured according to the fluctuation of the operating voltage value.

[0054] In one embodiment, after the battery detection device determines that the health state of the battery to be measured is unhealthy, it is necessary to further determine the cause of the fault of the battery to be measured according to the fluctuation of the working voltage value. For example, if the amplitude of the working voltage value drops sharply by more than 10% at the moment of load startup, the cause of the fault may be that the battery pole is oxidized or the connector is loose, resulting in an increase in contact resistance, or the battery internal resistance is abnormally increased. If the working voltage value continues to decrease linearly and cannot be restored, the cause of the fault may be battery capacity attenuation (remaining capacity <80%) or internal micro-short circuit, and the electrolyte decomposition causes the active material to fail. If the working voltage value increases abnormally or fluctuates in the opposite direction, the cause of the fault may be that the load polarity is reversed, causing a reverse current. The identification rules for specific fault causes can be set in advance by the user, or the battery detection device inputs the data of the working voltage value into a pre-trained fault identification model, and the fault identification model outputs the final fault cause, wherein the fault identification model can be obtained by pre-training a deep learning neural network, and the specific training process can refer to the prior art, which will not be repeated here.

[0055] In addition, when the battery testing device is suitable for a large number of battery health status detection scenarios, in order to improve the automation level and efficiency of battery detection, in one embodiment, the battery testing device also includes a battery conveying module, and the battery conveying module is used to transport the battery to be measured. For example, the battery conveying module includes a mechanical arm and a clamp, the clamp is used to clamp the battery, and the mechanical arm is used to convey the battery clamped by the clamp.

[0056] In step 102, when the current voltage value meets the preset precondition, the working voltage value detected by the voltage measurement module is collected, including:

[0057] Step 1021: When the current voltage value meets the preset precondition, control the battery conveying module to convey the battery to be measured to the target position so that the positive electrode and the negative electrode of the battery to be measured are connected to the load.

[0058] Step 1022: Collect the working voltage value detected by the voltage measurement module.

[0059] When the battery detection device determines that the current voltage value of the battery to be measured meets the preset precondition, the battery detection device controls the battery conveying module to convey the battery to be measured to the target position. After the battery to be measured is conveyed to the designated position, the positive and negative electrodes of the battery to be measured can be connected to the load. For example, there are multiple workstations on the production line of a factory, and a mainboard is fixed on each workstation. The battery slot on the mainboard is the target position to which the battery to be measured needs to be conveyed. After the fixture clamps the battery to be measured, the robot arm conveys the battery to be measured to the position corresponding to the battery slot of the mainboard, and the fixture then installs the battery to be measured into the battery slot. After the battery to be measured is installed in the battery slot of the mainboard, the mainboard can be started and the working voltage value of the battery to be measured can be collected through the voltage measurement module. In order to further improve the degree of automation, the battery detection device is also connected to the load in communication. After controlling the battery conveying module to convey the battery to be measured to the target position, before collecting the working voltage value detected by the voltage measurement module, it also includes: sending a start instruction to the load to start the load. After receiving the start instruction, the load can start automatically, so that no manual operation is required. It is understandable that after determining the health status of the battery to be measured, the battery detection device can further send a shutdown command to the load to shut down the load, thereby further improving the degree of automation in the batch testing process.

[0060] As mentioned above, the battery detection method provided by the present application collects the working voltage value of the battery when the battery drives the load to work, and determines the health status of the battery according to the fluctuation of the working voltage value. Compared with the prior art, it can greatly shorten the detection time of the battery health status and improve the detection efficiency, thereby solving the technical problem of low efficiency in detecting the health status of the battery in the prior art.
