Description

Technical Field

[0001] The present application relates to the field of battery testing technology, and in particular to a multi-range battery testing method, system, intelligent terminal and storage medium. Background Art

[0002] With the development of battery technology and the expansion of its application areas, especially the increasing demand for batteries in industries such as new energy vehicles, energy storage systems, drones, and portable electronic products, the corresponding demand for battery testing has also increased.

[0003] In the related art, during the battery testing process, the testing equipment will first roughly detect the battery voltage or current at the maximum range, and then adjust the test range to a more accurate range based on the voltage or current value. During the continuous battery testing, the battery voltage or current changes are detected in real time, so that the range can be adjusted in time to make the battery test more accurate.

[0004] With respect to the above-mentioned related technologies, when adjusting the range by real-time detection of changes in battery voltage or current, it is necessary to compare the voltage or current with the endpoint value of the range before selecting the range to switch. Therefore, there will be some interruptions in the process of switching the range. The interruptions in the process of switching the range can easily cause discontinuity in the measurement data, resulting in inaccurate battery test results. There is still room for improvement. Summary of the invention

[0005] In order to improve the accuracy of battery test results, the present application provides a multi-range battery testing method, system, intelligent terminal and storage medium.

[0006] In a first aspect, the present application provides a multi-range battery testing method, which adopts the following technical solution: A multi-range battery testing method, comprising: Get the test trigger information of the battery; Controlling the preset test equipment to select the range and test the battery according to the test trigger information to determine the battery test data information; Get relevant range information of the battery; Analyze the battery test data and related range information to determine the switching range information; After the test equipment switches the range according to the battery test data information and the switching range information, the battery continues to be tested to determine the battery test data information.

[0007] By adopting the above technical scheme, the control test equipment first selects the range and tests the battery to obtain the battery test data information, then selects the switching range information according to the battery test data information, and controls the test equipment to switch the range according to the battery test data information and the switching range information. Therefore, when the test data does not reach the switching range, the switching range is determined first, rather than temporarily switching the range according to the real-time detection data, thereby ensuring the continuity of the test data and improving the accuracy of the battery test results.

[0008] Optionally, the step of controlling the test equipment to switch the range according to the battery test data information and the switching range information to continue testing the battery to determine the battery test data information includes: Analyze the battery test data information to determine the test data change rate information; Get the current range information and current test data information of the battery; Analyze the current range information and the switching range information to determine the range switching value information; Analyze the range switching value information and the current test data information to determine the remaining test data range information; Analyze the remaining test data range information and the test data change speed information to determine the switching time information; According to the switching time information, the test equipment is controlled to switch the range to the switching range information to test the battery to determine the battery test data information.

[0009] By adopting the above technical scheme, the switching time information of the test data reaching the range switching value is obtained according to the analysis of the test data change speed information and the remaining test data range information, and then the test equipment is controlled according to the switching time information to switch the range to the switching range information to test the battery to determine the battery test data information, thereby improving the accuracy of the range switching.

[0010] Optionally, the step of controlling the test equipment to switch the range to the switching range information according to the switching time information to test the battery to determine the battery test data information includes: Get the tested time information of the tested equipment; Determine whether the tested time information meets the requirements of switching time information; If it does not meet the requirement, continue to obtain the tested time information for cyclic judgment; If it meets the requirements, the test equipment is controlled to switch the range according to the switching range information and the current range information to test the battery to determine the battery test data information.

[0011] By adopting the above technical scheme, when the tested time information meets the requirements of the switching time information, that is, when the two are equal, it indicates that the test data is speculated to be close to the range switching value. Therefore, the test equipment is controlled to switch the range according to the switching range information and the current range information to test the battery to determine the battery test data information, thereby improving the accuracy of the range switching.

[0012] Optionally, the step of controlling the test equipment to switch the range to test the battery according to the switching range information and the current range information to determine the battery test data information includes: When the tested time information meets the requirements of the switching time information, the test device is controlled to start the measurement channel corresponding to the switching range information; Control the test equipment to test the battery with the switching range information to determine the first test data information, and synchronously control the test equipment to test the battery with the current range information to determine the second test data information; Determining whether the second test data information meets the requirements of the switching range information; If not, the second test data information is defined as battery test data information; If it is in compliance, the first test data information is defined as battery test data information, and the test device is controlled to close the measurement channel corresponding to the current range information.

[0013] By adopting the above technical scheme, the battery is tested according to the switching range information and the current range information at the same time. When the second test data information meets the requirements of the switching range information, it indicates that the test data has entered the switching range information, and the first test data information is defined as the battery test data information. When it does not meet the requirements, it indicates that the test data is still within the current range information, and the second test data information is still used as the battery test data information, thereby ensuring the continuity of the test data and improving the accuracy of the battery test.

[0014] Optionally, after the control test device starts the measurement channel corresponding to the switching range information, a calibration step for the measurement channel corresponding to the switching range information is further included, and the specific steps include: Analyze the switching range information to determine the calibration range information, and control the test equipment to start the calibration channel corresponding to the calibration range information; Control the test equipment to synchronously measure the preset calibration data information with the measurement channel corresponding to the switching range information and the calibration channel corresponding to the calibration range information to determine the switching range data information and the calibration range data information; Analyze the switching range data information and the calibration range data information to determine the adjustment data information; The test equipment is controlled according to the adjustment data information to calibrate the measurement channel corresponding to the switching range information.

[0015] By adopting the above technical solution, before testing the battery with the measurement channel corresponding to the switching range information, first start the calibration channel corresponding to the calibration range information, and then test the two channels at the same time with the calibration data information, and obtain the adjustment data information based on the test data analysis of the two channels, so as to adjust the measurement channel corresponding to the switching range information according to the adjustment data information, thereby improving the accuracy of the test channel corresponding to the switching range information.

[0016] Optionally, the step of analyzing the battery test data information to determine the test data change rate information includes: Analyze the battery test data information to determine the calculation data information and the calculation time information corresponding to the calculation data information; Analyze the calculation data information and calculation time information to determine the basic data change speed information; Analyze the speed of change of basic data to determine the speed change trend information; The speed change trend information and the basic data change speed information are analyzed to determine the test data change speed information.

[0018] Optionally, the step of analyzing the battery test data information and the related range information to determine the switching range information includes: Analyze the battery test data information to determine the test data change trend information; Determine whether the test data change trend information meets the preset change trend information requirements; If it is in compliance, the trigger information and related range information are analyzed according to the preset large range to determine the switching range information; If it does not meet the requirements, the trigger information and related range information are analyzed according to the preset small range to determine the switching range information.

[0019] By adopting the above technical scheme, when it is determined that the test data change trend information meets the requirements of the increasing trend information, it indicates that the test data is gradually increasing. Therefore, the trigger information is determined based on the large range to determine the large range in the related range information as the switching range information. When it does not meet the requirements, it indicates that the test data is decreasing. Therefore, the trigger information is determined based on the small range to determine the small range in the related range information as the switching range information, thereby improving the convenience of determining the switching range information.

[0034] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-Figure 7 It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0035] The embodiment of the present application discloses a multi-range switching method for a battery testing process, and specifically discloses a processing terminal and a test device. The processing terminal and the test device are connected via a data wire to realize data interaction and control. After the processing terminal receives the test trigger information of the battery, the processing terminal controls the test device in response to the test trigger information to select and test the battery according to a conventional test process, thereby obtaining battery test data information, and then calls relevant range information, selects the next switching range information required by the battery in the relevant range information according to the battery test data information, and then controls the test device to switch the range when necessary according to the battery test data information and the switching range information to continue testing the battery, thereby determining in advance that after the switching range, there is no need for temporary analysis and determination to cause the test to be interrupted, thereby improving the accuracy of the battery test.

[0036] Reference Figure 1 The present application embodiment discloses a multi-range battery testing method, comprising the following steps: Step S100: Acquire battery test trigger information.

[0037] Among them, the test trigger information refers to the trigger data for starting the test when the battery is connected to the test equipment. The test equipment uses six-wire sampling technology to detect the contact impedance in real time. When it is determined that the contact impedance is within the preset range, it indicates that the battery connection is successful, and the test trigger information is sent to the processing terminal.

[0038] Step S101: controlling a preset test device to select a range and test a battery according to the test trigger information to determine the battery test data information.

[0039] Among them, after the processing terminal receives the test trigger information, the processing terminal responds to the test trigger information, thereby controlling the test equipment to measure the approximate data of the battery according to the maximum range, and then selects a more accurate range to test the battery according to the approximate data to obtain battery test data information.

[0040] The test equipment refers to the equipment used to test the battery. The specific test type is determined by the operator based on the actual situation. The test equipment includes an automatic range switching system, including an amplifier for amplifying the input signal. The amplified signal enters the PGA, and different gains are set according to the required range. The PGA output is connected to the ADC for analog-to-digital conversion. The digital output of the ADC can be transmitted to the microcontroller through the SPI interface. The number of channels of the automatic range switching system and the range corresponding to each channel are determined by the operator based on the actual situation.

[0041] Battery test data information refers to data collected after the battery test, including voltage and current data, which is obtained by the processing terminal controlling the test equipment to select the range and then testing the battery.

[0042] Step S102: Obtain relevant range information of the battery.

[0043] The relevant range information refers to the possible range of the battery for the next switching. The processing terminal calls the current range of the battery test by the test equipment, and then calls two ranges greater than the current range and less than the current range to obtain the relevant range information.

[0044] Step S103: Analyze the battery test data information and related range information to determine the switching range information.

[0045] The switching range information refers to the range to be used next in the battery test, which is determined by the processing terminal after analyzing the battery test data information and related range information. For specific analysis methods, refer to Figure 7 steps.

[0046] Step S104: Control the test equipment to switch the range according to the battery test data information and the switching range information, and then continue to test the battery to determine the battery test data information.

[0047] After the processing terminal determines the switching range information, the processing terminal controls the test equipment to switch the range when the battery needs it according to the battery test data information and the switching range information, and continues to test the battery with the new range to obtain the battery test data information. For specific methods, refer to Figure 2 The battery test data information in this step is consistent with the battery test data information in step S101, except that the test equipment is tested with a different range.

[0048] Reference Figure 2 The steps of controlling the test equipment to switch the range according to the battery test data information and the switching range information to continue testing the battery to determine the battery test data information include: Step S200: Analyze the battery test data information to determine the test data change rate information.

[0049] The test data change rate information refers to the speed at which the subsequent test data changes. The change rate is a variable value. The change rate may be larger or smaller depending on the time of continued testing. It is determined by the processing terminal after analyzing the battery test data information. For specific analysis methods, refer to Figure 6 steps.

[0050] Step S201: Obtain the current range information and current test data information of the battery.

[0051] The current range information refers to the current range of the battery tested by the test equipment, which is identified by the test equipment and sent to the processing terminal. The current test data information refers to the current data of the battery detected by the test equipment.

[0052] Step S202: Analyze the current range information and the switching range information to determine the range switching value information.

[0053] Among them, the range switching value information refers to the specific value of the test data when switching the range, which is determined by the boundary value between the range corresponding to the switching range information and the range corresponding to the current range information. For example, if the current range information is a large range and the switching range information is a small range, then the maximum value of the switching range information is determined to be the range switching value information; if the current range information is a small range and the switching range information is a large range, then the maximum value of the current range information is determined to be the range switching value information.

[0054] Step S203: Analyze the range switching value information and the current test data information to determine the remaining test data range information.

[0055] The remaining test data range information refers to the range in which the test data can vary before switching the range, and is obtained by calculating the absolute value of the difference between the numerical value corresponding to the range switching value information and the numerical value corresponding to the current test data information by the processing terminal.

[0056] Step S204: Analyze the remaining test data range information and the test data change speed information to determine the switching time information.

[0057] Among them, the switching time information refers to the time value from the current time to the start of the range switching, which is obtained by the processing terminal after taking the quotient of the numerical value corresponding to the remaining test data range information and the test data change speed information. The specific method is: call the front change speed in the test data change speed information one by one, and then call the remaining test data and the change speed to take the quotient to obtain the change time, until all the remaining test data are calculated, and then sum up the change time to obtain the switching time information.

[0058] Step S205: Control the test equipment to switch the measurement range to the switching measurement range information according to the switching time information to test the battery to determine the battery test data information.

[0059] After the processing terminal obtains the switching time information, the processing terminal controls the test equipment to switch the range to the range corresponding to the switching range information according to the switching time information, thereby continuing to test the battery to obtain the battery test data information. For specific methods, refer to Figure 3 The battery test data information in this step is consistent with the battery test data information in step S104.

[0060] Reference Figure 3 The steps of controlling the test equipment to switch the range to the switching range information according to the switching time information to test the battery and determine the battery test data information include: Step S300: Acquire the tested time information of the testing device.

[0061] The tested time information refers to the test time starting from when the current test data information is obtained, which is counted by a timer and sent to the processing terminal.

[0062] Step S301: Determine whether the tested time information meets the requirement of switching time information.

[0063] The requirement of the switching time information refers to the consistency with the time corresponding to the switching time information. The processing terminal determines whether the time corresponding to the tested time information is consistent with the time corresponding to the switching time information, thereby determining whether the test data is close to the range switching value.

[0064] Step S3011: If not, continue to obtain the tested time information for cyclic determination.

[0065] Among them, if the processing terminal determines that the time corresponding to the tested time information is inconsistent with the time corresponding to the switching time information, it means that the test data is not close to the range switching value, so the tested time information continues to be obtained, thereby continuing to pay attention to changes in the test time.

[0066] Step S3012: If it is in compliance, the test equipment is controlled to switch the range according to the switching range information and the current range information to test the battery to determine the battery test data information.

[0067] If the processing terminal determines that the time corresponding to the tested time information is consistent with the time corresponding to the switching time information, it indicates that the test data is close to the range switching value, so the range needs to be switched, and the test equipment is controlled to switch the range according to the switching range information and the current range information to test the battery and obtain the battery test data information. For specific methods, refer to Figure 4 steps.

[0068] Reference Figure 4 The steps of controlling the test equipment to switch the range to test the battery according to the switching range information and the current range information to determine the battery test data information include: Step S400: When the tested time information meets the requirement of the switching time information, the test device is controlled to start the measurement channel corresponding to the switching range information.

[0069] When the processing terminal determines that the time corresponding to the tested time information is consistent with the time corresponding to the switching time information, the test device is controlled to start the measurement channel corresponding to the switching range information to provide basic support for subsequent switching ranges.

[0070] Step S401: Control the test equipment to test the battery with the switched range information to determine the first test data information, and synchronously control the test equipment to test the battery with the current range information to determine the second test data information.

[0071] Among them, after the processing terminal turns on the measurement channel corresponding to the switching range information, the processing terminal controls the test equipment to test the battery with the measurement channel corresponding to the switching range information to determine the first test data information, and synchronously controls the test equipment to test the battery with the measurement channel corresponding to the current range information to determine the second test data information, thereby providing data support for the subsequent determination of whether to switch the range.

[0072] The first test data information refers to data obtained by the test device when testing the battery using the measurement channel corresponding to the switching range information, and the second test data information refers to data obtained by the test device when testing the battery using the measurement channel corresponding to the current range information.

[0073] Step S402: Determine whether the second test data information meets the requirements of the switching range information.

[0074] The requirement of the switching range information refers to the value falling within the range corresponding to the switching range information. The processing terminal determines whether the data corresponding to the second test data information falls within the range corresponding to the switching range information, thereby determining whether the range needs to be switched, and providing data support for the subsequent determination of the battery test data information.

[0075] Step S4021: If not, define the second test data information as battery test data information.

[0076] Among them, if the processing terminal determines that the data corresponding to the second test data information does not fall within the range corresponding to the switching range information, it indicates that the test data is still within the range corresponding to the current range information. Therefore, the second test data information is defined as battery test data information, and the test continues with the current range and the switching range, so as to continuously monitor the changes in the data.

[0077] Step S4022: If it is in compliance, the first test data information is defined as battery test data information, and the test device is controlled to close the measurement channel corresponding to the current range information.

[0078] Among them, if the processing terminal determines that the data corresponding to the second test data information falls within the range corresponding to the switching range information, it indicates that the range needs to be switched to test the battery. Therefore, the first test data information is defined as battery test data information, and the test equipment is controlled to close the measurement channel corresponding to the current range information, and only retain the measurement access corresponding to the switching range information, so that the test equipment can complete the range switching without interrupting the test.

[0079] Reference Figure 5 After the test device is controlled to start the measurement channel corresponding to the switching range information, the method further includes a calibration step for the measurement channel corresponding to the switching range information. The specific steps include: Step S500: analyzing the switching range information to determine the calibration range information, and controlling the test device to start the calibration channel corresponding to the calibration range information.

[0080] Among them, after the processing terminal determines the calibration range information according to the switching range information, the processing terminal controls the test equipment to start the calibration channel corresponding to the calibration range information, thereby providing data support for subsequently improving the accuracy of the measurement channel corresponding to the switching range information through the calibration channel corresponding to the calibration range information.

[0081] The calibration range information refers to the range channel used to calibrate the measurement channel corresponding to the switching range information. The range corresponding to the calibration range information is consistent with the range corresponding to the switching range information, and is selected by the processing terminal from the preset calibration range according to the range corresponding to the switching range information.

[0082] Step S501: controlling the test equipment to synchronously measure the preset calibration data information with the measurement channel corresponding to the switching range information and the calibration channel corresponding to the calibration range information to determine the switching range data information and the calibration range data information.

[0083] Among them, after the processing terminal controls the test equipment to start the calibration channel corresponding to the calibration range information, the processing terminal controls the test equipment to use the data corresponding to the calibration data information as the input signal, and at the same time performs measurement with the measurement channel corresponding to the switching range information and the calibration channel corresponding to the calibration range information, thereby obtaining the switching range data information and the calibration range data information, providing data support for the subsequent adjustment of the measurement channel corresponding to the switching range information.

[0084] The calibration data information refers to the stable signal input when the calibration switching range information corresponds to the measurement channel. The specific value is determined by the operator according to the actual situation. The switching range data information refers to the data obtained by the test equipment when measuring the calibration data information with the switching range information corresponding to the measurement channel. The calibration range data information refers to the data obtained by the test equipment when measuring the calibration data information with the calibration range information corresponding to the calibration channel.

[0085] Step S502: Analyze the switching range data information and the calibration range data information to determine the adjustment data information.

[0086] Among them, the adjustment data information refers to adjusting the gain and offset data of the measurement channel corresponding to the switching range information. The processing terminal compares the switching range data information and the calibration range data information to determine that when the switching range data information is inconsistent with the calibration range data information, the deviation between the two is determined, and the gain error or offset error is determined based on the deviation, and the gain adjustment amount or offset adjustment amount is further determined based on the deviation, providing data support for subsequent adjustments.

[0087] Step S503: Control the test equipment to calibrate the measurement channel corresponding to the switching range information according to the adjustment data information.

[0088] Among them, after the processing terminal determines the adjustment data information, if the adjustment data information is a gain adjustment amount, the gain value of the PGA is set according to the gain adjustment amount; if the adjustment data information is an offset adjustment amount, the bias voltage is set according to the offset adjustment amount, so that the measurement data of the measurement channel corresponding to the switching range information is more accurate.

[0089] Reference Figure 6 The steps of analyzing the battery test data information to determine the test data change speed information include: Step S600: Analyze the battery test data information to determine the calculation data information and the calculation time information corresponding to the calculation data information.

[0090] The calculation data information refers to the test data used to determine the test data change speed information, which is obtained by selecting part of the battery test data information by the processing terminal. The calculation time information refers to the time when the calculation data information is measured, which is obtained by the processing terminal based on the calculation data information.

[0091] Step S601: Analyze the calculation data information and the calculation time information to determine the basic data change speed information.

[0092] Among them, the basic data change rate information refers to the calculation data that changes per unit time. The processing terminal divides the calculation time information into multiple unit times, and then calls the calculation data change amount corresponding to the unit time. The multiple change speeds are obtained by summing the calculation data change amount and the unit time, which is the basic data change rate information.

[0093] Step S602: Analyze the basic data change speed information to determine the speed change trend information.

[0094] Among them, speed change trend information refers to the relationship between data change speed and data, including three types: the smaller the data, the faster the data change speed; the smaller the data, the slower the data change speed; and the data change speed is constant. The processing terminal uses multiple change speeds corresponding to the basic data change speed information as the vertical coordinate and the middle value of the calculated data corresponding to each change speed as the horizontal coordinate to draw a curve graph.

[0095] Step S603: Analyze the speed change trend information and the basic data change speed information to determine the test data change speed information.

[0096] Among them, the test data change speed information in this step is consistent with the test data change speed information in step S200. The processing terminal determines the change speed corresponding to the minimum data in the basic data change speed information in the curve chart corresponding to the speed change trend information, and then infers the speed of subsequent data changes along the curve based on the change speed as the starting point.

[0097] Reference Figure 7 The steps of analyzing the battery test data information and the related range information to determine the switching range information include: Step S700: Analyze the battery test data information to determine the test data change trend information.

[0098] The test data change trend information refers to the change trend of the battery test data, including increasing and decreasing, which is obtained by comparing the battery test data obtained successively by the processing terminal.

[0099] Step S701: Determine whether the test data change trend information meets the preset requirement of the change trend information.

[0100] The increasing trend information refers to the increasing trend of the battery test data, and the increasing trend information requirement refers to the trend corresponding to the increasing trend information, which is stored in the processing terminal by the operator. The processing terminal determines whether the trend corresponding to the test data change trend information is consistent with the trend corresponding to the increasing trend information, thereby providing data support for the subsequent determination of the switching range.

[0101] Step S7011: If it is in compliance, the trigger information and related range information are analyzed according to the preset large range to determine the switching range information.

[0102] Among them, if the processing terminal determines that the trend corresponding to the test data change trend information is consistent with the trend corresponding to the increasing trend information, it indicates that the test data is increasing, and therefore a larger range switching is required, thereby determining that the large range in the relevant range information is the switching range information based on the trigger data corresponding to the trigger information determined by the large range.

[0103] The large range determination trigger information refers to trigger data for determining the large range as a switching range, and is stored in the processing terminal by the operator.

[0104] Step S7012: If not, the trigger information and related range information are analyzed according to the preset small range to determine the switching range information.

[0105] Among them, if the processing terminal determines that the trend corresponding to the test data change trend information is inconsistent with the trend corresponding to the increasing trend information, it indicates that the test data is getting smaller, and therefore a smaller range switch is required. Therefore, the small range in the relevant range information is determined as the switching range information based on the trigger data corresponding to the trigger information determined based on the small range.

[0106] The small range determination trigger information refers to trigger data for determining the small range as the switching range, and is stored in the processing terminal by the operator.
