Description

Technical Field

[0001] This application relates to the field of battery management technology, specifically to a battery detection method, a battery power calibration method, an apparatus, and an atomizing device. Background Technology

[0002] As a core component of electronic devices, the battery's operating state directly affects the user experience and the reliability of the device. Therefore, accurately determining the battery's charge-voltage relationship is crucial for a battery management system to effectively manage battery operation.

[0003] Currently, the technical methods for determining the battery's charge-voltage relationship typically involve: determining the theoretical charge-discharge curve of the battery through capacity testing, conducting charging tests on the batteries in the product, recording multiple voltage data points during battery operation, and manually calculating the charge corresponding to each voltage data point. By comparing the charge calculated for each voltage data point with the theoretical charge corresponding to the voltage data on the theoretical charge-discharge curve, and in cases where the two differ, manually re-determining the charge corresponding to that voltage data point based on experience, the battery's charge-voltage mapping relationship is ultimately established.

[0004] However, the battery charge-voltage mapping relationship established based on human experience relies too heavily on subjective experience. This means the accuracy of the mapping relationship is affected not only by computational precision but also by individual differences in experience. Consequently, the battery charge-voltage relationship determined by current methods has relatively low accuracy, which in turn affects the accuracy of the actual battery charge obtained through calibration based on this relationship.

[0017] In some embodiments, a battery detection device is provided, applied to an atomizing device; the device includes: The charge / discharge module is used to perform alternating charge and discharge processes on the battery. A detection module is used to detect multiple first real-time voltages of the battery during the charging process; the alternating charge-discharge process is configured to charge the battery with its rated capacity in a single charge.

[0021] By analogy, an accurate mapping relationship between multiple real-time battery charge levels and average charging voltages can be obtained, resulting in charging mapping data. Since the real-time battery charge level corresponding to each average charging voltage is an accurate value calculated based on the battery's initial charge level, the rated charge level for a single charge, and the number of charge cycles, rather than relying on manual estimation or theoretical curves, data errors introduced by differences in human experience or mismatched external testing environments can be avoided, effectively ensuring the accuracy of the battery voltage-charge mapping relationship in the charging mapping data.

[0025] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0026] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0027] refer to Figure 1 The diagram illustrates a flowchart of a battery detection method provided in an embodiment of this application. The battery detection method is applied to an atomizing device. Figure 1 As shown, the method includes: Step 101: Perform alternating charge-discharge processing on the battery to obtain multiple first real-time voltages of the battery during the charging process. The alternating charge-discharge processing is configured to charge the battery to its rated capacity in a single cycle.

[0028] In this embodiment of the application, during the alternating charge and discharge process of the battery, multiple first real-time voltages of the battery can be obtained for each charging process, so as to obtain multiple first real-time voltages corresponding to each charging process.

[0029] This process involves alternating charge and discharge cycles, where the battery undergoes a charge-discharge cycle. This cycle is configured to first charge the battery to a fixed rated capacity, then discharge it, completing one full charge-discharge cycle. This cycle is repeated to create alternating charge and discharge cycles for the battery.

[0030] In some alternative embodiments, discharging the battery can refer to the process of discharging the battery. In other embodiments, discharging the battery can also refer to a resting process after stopping charging, to simulate the battery's discharge process. During the resting process after stopping charging, the battery is neither charging nor driving an external load and is in a resting state. The battery voltage is not disturbed by the charging voltage and gradually stabilizes from a higher value in the charging state. Since in practical applications, when the battery supplies power to an external load, i.e., when the battery is discharging, its operating state also starts from a stable resting state, the resting state voltage after stopping charging can be considered as the initial voltage in the battery discharge process. Therefore, the resting process after stopping charging can be regarded as simulating the battery discharge process.

[0031] In some embodiments, the specific value of the rated capacity can be adjusted according to the capacity characteristics of different battery models. For example, the rated capacity can be 5 mAh, 10 mAh, or 15 mAh. The charging stop time can be adjusted according to the physical characteristics of the battery and the external environment. For example, in low-temperature environments, the charging stop time can be extended to ensure battery voltage stability.

[0032] For example, alternating charge and discharge processing can be performed by an external host computer controlled by a controller in the atomizing device. The controller in the atomizing device starts the external host computer to enable the external host computer to perform alternating charging processing on the battery. The host computer can be a power supply or an ASD-906B battery simulator.

[0033] Step 102: Calculate the real-time battery capacity based on the battery's initial capacity, rated capacity, and number of charging cycles.

[0034] In this embodiment of the application, the real-time battery level after each charging process can be calculated based on the battery's initial charge, rated charge, and number of charging cycles. This allows us to obtain the real-time battery level after each charging process during the alternating charge and discharge cycle, which is also the real-time battery level when each charging cycle is completed.

[0035] Here, the initial battery capacity represents the battery's capacity before the first alternating charge-discharge cycle. The number of charge cycles represents the number of alternating charge-discharge cycles performed on the battery. During the alternating charge-discharge cycle, the real-time battery capacity Qi after the i-th charge cycle satisfies: Qi = Q0 + ΔQ × i. Since the initial battery capacity, rated battery capacity, and the number of charge cycles are all accurately quantified values, the accuracy of the calculated battery capacity can be ensured, effectively clarifying the real-time battery capacity after each charge cycle.

[0036] In some embodiments, the number of charging cycles can be counted by a controller in the atomizing device, with the controller incrementing the number of charging cycles by one after each charge-discharge process. Further optionally, the battery's charge capacity can be determined based on the charging current and charging time; for example, the charge capacity Q2 = Iavg × Δt. Δt represents the charging time, which can be in hours or seconds. Q2 represents the amount of charge injected into the battery during the charging time Δt, which can be in ampere-hours or milliampere-hours. Iavg represents the average current during the charging time Δt, which can be in amperes or milliamperes. Furthermore, since the battery's charging current can be obtained in real time through detection, the charge capacity of the battery during a single charge can be controlled by adjusting the charging time based on the real-time charging current, thereby ensuring that the battery is charged with the rated capacity in a single charge.

[0037] Step 103: Obtain the average charging voltage corresponding to the real-time power based on multiple first real-time voltages.

[0038] In some embodiments of this application, as described above, during the alternating charge-discharge process of the battery, multiple first real-time voltages of the battery can be obtained during each charge. Furthermore, for each charge process, the average of the multiple first real-time voltages of the battery during that charge process is calculated to obtain an average charging voltage. This average charging voltage can be considered as the battery voltage after that charge process, corresponding to the real-time charge level of the battery after that charge process. Similarly, based on the multiple first real-time voltages of the battery during each charge process, the average charging voltage corresponding to the real-time charge level of the battery after each charge process can be obtained. Since the alternating charge-discharge process is repeated cyclically, a series of discrete and precise real-time charge levels can be determined by performing multiple charge-discharge processes on the battery, thereby determining an average charging voltage corresponding to each real-time charge level.

[0039] For example, assume that the alternating charge-discharge process of the battery includes: a first charge-discharge process, a second charge-discharge process, and a third charge-discharge process (i.e., i = 3). The atomizing device acquires j first real-time voltages V111-V11j during the charging process of the first charge-discharge process, calculates the real-time charge Q1 of the battery after this charging process, and calculates the average of the n first real-time voltages V111-V11j to obtain the average charging voltage Vavg11 corresponding to the real-time charge Q1. The atomizing device acquires n first real-time voltages V121-V12j during the charging process of the second charge-discharge process, calculates the real-time charge Q2 of the battery after this charging process, and calculates the average of the j first real-time voltages V121-V12j to obtain the average charging voltage Vavg12 corresponding to the real-time charge Q2. The atomizing device acquires j first real-time voltages V131-V13j during the charging process of the battery in the third charge-discharge process, calculates the real-time charge Q3 of the battery after this charging process, and calculates the average value of the j first real-time voltages V131-V13j to obtain the average charging voltage Vavg13 corresponding to the real-time charge Q3.

[0040] By calculating the average of multiple first real-time voltages during a single charge, voltage fluctuations and noise interference that occur during battery charging can be effectively avoided, thus preventing the accuracy of confirming the battery voltage after a single charge.

[0041] Furthermore, as the battery charge increases to a higher level, the voltage's sensitivity to changes in charge decreases, resulting in a more gradual voltage rise. Even small voltage measurement deviations can compromise the accuracy of the mapping between battery charge and voltage. Therefore, a single measurement of the battery voltage during each charge cycle may not accurately represent the final battery voltage after the charging process. Consequently, by collecting multiple first real-time voltages during each charge cycle and calculating the average of these voltages, a charging voltage average is obtained. This average charging voltage is then used to accurately represent the final battery voltage after the charging process, effectively ensuring the accuracy of the battery voltage.

[0042] For example, when the battery voltage exceeds 3.9V, the voltage change becomes gradual as the battery continues to charge. Even small voltage measurement deviations can lead to significant errors in the mapping data between battery charge and voltage, affecting the accuracy of this mapping. It should be noted that other algorithms can also be used to obtain the average charging voltage corresponding to the real-time charge based on multiple first real-time voltages. For instance, the average of the first real-time voltages (excluding the maximum and minimum values) can be used as the average charging voltage corresponding to the real-time charge. This reduces the impact of interference factors on the first real-time voltages and allows them to be included in the calculation of the average charging voltage, making the average charging voltage more accurately reflect the battery voltage after charging.

[0043] Step 104: Obtain charging mapping data based on the real-time battery level and the corresponding average charging voltage. The charging mapping data is configured to determine the battery's real-time battery level based on the battery's charging voltage.

[0044] In this embodiment, the charging mapping data is a dataset established by performing alternating charge and discharge processing on the battery, resulting in multiple real-time battery levels and the average charging voltage corresponding to each real-time battery level. It indicates the mapping relationship between battery level and voltage during the charging process. Specifically, the charging mapping data includes: the real-time battery level after multiple charging processes, and the average charging voltage corresponding to each real-time battery level. For example, continuing with the example in step 103 above, the charging mapping data includes: real-time battery levels Q1, Q2, and Q3, and the average charging voltage Vavg11 corresponding to real-time battery level Q1, the average charging voltage Vavg12 corresponding to real-time battery level Q2, and the average charging voltage Vavg13 corresponding to real-time battery level Q3.

[0045] Specifically, the charging mapping data is configured to determine the real-time battery level based on the battery's charging voltage. Optionally, during the charging process, the atomizing device acquires the battery's actual charging voltage and charging mapping data, and determines the real-time battery level corresponding to the actual charging voltage based on the charging mapping data, thereby obtaining the actual charging capacity of the battery and accurately confirming the actual charging status of the battery.

[0046] In some embodiments, charging mapping data can be recorded in the form of lookup tables, matrices, or fitted curves. For example, charging mapping data can be recorded in the form of a lookup table to obtain a battery charge-charging voltage mapping table. During charging, the atomizing device can obtain the actual charging voltage of the battery and determine the actual charging capacity by querying the battery charge-charging voltage mapping table, thus accurately confirming the actual charging status of the battery. Furthermore, the atomizing device can also display the determined battery charging capacity in real time during charging, allowing users to accurately understand the battery's charging status and improving the reliability and user experience of the atomizing device.

[0047] In this embodiment, the battery is subjected to alternating charge-discharge processing, configured to charge the battery with its rated capacity in a single charge. After each charge, multiple first real-time voltages of the battery during the charging process are acquired. Based on the battery's initial capacity, the rated capacity charged in a single charge, and the number of charges, the real-time capacity of the battery at the end of that charge is calculated. The average of these multiple first real-time voltages during that charge is then calculated to obtain the average charging voltage corresponding to a given real-time capacity. This process is repeated to obtain an accurate mapping relationship between the battery's multiple real-time capacities and the average charging voltage, resulting in charging mapping data. Since the real-time capacity corresponding to each average charging voltage is an accurate value calculated based on the battery's initial capacity, the rated capacity charged in a single charge, and the number of charges, rather than relying on manual estimation or theoretical curves, data errors introduced due to differences in human experience or mismatched external testing environments can be avoided, effectively ensuring the accuracy of the battery voltage-capacity mapping relationship in the charging mapping data. Furthermore, since the battery detection method provided in this application can be directly applied to actual devices to directly obtain charging mapping data of the actual devices, the battery voltage and capacity mapping relationship recorded in the charging mapping data matches the device environment. Compared with related technologies, this application can effectively eliminate the error in the battery voltage and capacity mapping relationship caused by the mismatch between the capacity distribution cabinet environment and the device environment, further ensuring the accuracy of the battery voltage and capacity mapping relationship.

[0048] In some embodiments of this application, such as Figure 2 As shown, the battery testing method also includes: Step 201: Obtain multiple second real-time voltages of the battery during the discharge process.

[0049] In this embodiment of the application, during the alternating charge and discharge process of the battery, multiple second real-time voltages of the battery can be obtained for each discharge process, so as to obtain multiple second real-time voltages corresponding to each discharge process.

[0050] In some optional embodiments, discharging the battery may refer to the process of discharging the battery. Accordingly, alternatively, multiple second real-time voltages of the battery can be acquired during each battery discharge process. In other embodiments, discharging the battery may also refer to a resting process after charging is stopped, to simulate the battery discharge process. Accordingly, alternatively, multiple second real-time voltages of the battery during the resting process after each charging stop can be acquired.

[0051] Step 202: Obtain the average discharge voltage corresponding to the real-time charge based on multiple second real-time voltages.

[0052] In some embodiments of this application, discharging the battery can also refer to a resting process after stopping battery charging, used to simulate the battery's discharge process. Therefore, the real-time battery charge after each charging process is also the real-time battery charge at the beginning of each discharge process. Furthermore, since the battery voltage change is essentially static during this resting process, the second real-time voltage collected during this resting process can be considered the battery voltage at the beginning of the discharge process.

[0053] Optionally, during the alternating charge-discharge process, multiple second real-time voltages of the battery can be obtained during each resting process (discharge process). Then, for each resting process, the average of these multiple second real-time voltages is calculated to obtain the average discharge voltage. This average discharge voltage can be considered the battery voltage at the beginning of the discharge process, corresponding to the real-time charge level at the beginning of the discharge process. Similarly, based on the multiple second real-time voltages during each resting process, the average discharge voltage corresponding to the real-time charge level at the beginning of each discharge process can be obtained. Since the alternating charge-discharge process is repeated cyclically, a series of discrete and precise real-time charges can be determined by performing multiple charge-discharge processes on the battery, thereby determining an average discharge voltage corresponding to each real-time charge level.

[0054] In other embodiments of this application, discharging the battery may refer to the process of discharging the battery. Alternating charge-discharge processing is also configured to discharge the battery to a second rated capacity in a single cycle. To distinguish it from the second rated capacity, the rated capacity charged into the battery in a single cycle may be referred to as the first rated capacity. The second rated capacity is less than the first rated capacity.

[0055] Optionally, during the alternating charge-discharge process, multiple second real-time voltages of the battery can be obtained during each discharge. Then, for each discharge process, the average of these multiple second real-time voltages is calculated to obtain the average discharge voltage. This average discharge voltage can be considered the battery voltage at the beginning of the discharge process, corresponding to the real-time charge level at the beginning of the discharge process. Similarly, based on the multiple second real-time voltages during each discharge process, the average discharge voltage corresponding to the real-time charge level at the beginning of each discharge process can be obtained. Since the alternating charge-discharge process is repeated cyclically, a series of discrete and precise real-time charge levels can be determined through multiple charge-discharge processes, thereby determining an average discharge voltage corresponding to each real-time charge level.

[0056] For example, continuing with the example from step 103 above. Assume the alternating charge-discharge process of the battery includes: a first charge-discharge process, a second charge-discharge process, and a third charge-discharge process (i.e., i = 3). The atomizing device acquires j second real-time voltages V211-V21j during the discharge process of the battery in the first charge-discharge process, calculates the average value of the j second real-time voltages V211-V21j, and obtains the average discharge voltage Vavg21 corresponding to the real-time charge Q1. The atomizing device acquires j second real-time voltages V221-V22j during the discharge process of the battery in the second charge-discharge process, calculates the average value of the j second real-time voltages V221-V22j, and obtains the average discharge voltage Vavg22 corresponding to the real-time charge Q2. The atomizing device acquires j second real-time voltages V231-V23j during the discharge process of the battery in the third charge-discharge process, calculates the average value of the j second real-time voltages V231-V23j, and obtains the average discharge voltage Vavg23 corresponding to the real-time charge Q3.

[0057] By calculating the average of multiple second real-time voltages during a single discharge, voltage fluctuations and noise interference that occur during battery discharge can be effectively avoided, thus preventing the accuracy of confirming the battery voltage at the beginning of a single discharge. It should be noted that other algorithms can also be used to obtain the average discharge voltage corresponding to the real-time charge based on multiple second real-time voltages. For example, the average of the second real-time voltages (excluding the maximum and minimum values) can be determined as the average discharge voltage corresponding to the real-time charge. This reduces the impact of interference factors on the second real-time voltages and allows them to be included in the calculation of the average discharge voltage, making the average discharge voltage more accurately reflect the battery voltage at the beginning of the discharge process.

[0058] Step 203: Obtain discharge mapping data based on the real-time battery level and the corresponding average discharge voltage. The discharge mapping data is configured to determine the battery's real-time battery level based on the battery's discharge voltage.

[0059] In this embodiment, the discharge mapping data is a dataset established by performing alternating charge and discharge processes on the battery, resulting in multiple real-time battery levels and the average discharge voltage corresponding to each real-time battery level. It indicates the mapping relationship between battery level and voltage during the battery discharge process. Specifically, the discharge mapping data includes: the real-time battery level after multiple charge processes, and the average discharge voltage corresponding to each real-time battery level. For example, continuing with the example in step 202 above, the discharge mapping data includes: real-time battery levels Q1, Q2, and Q3, and the average discharge voltage Vavg21 corresponding to real-time battery level Q1, the average discharge voltage Vavg22 corresponding to real-time battery level Q2, and the average discharge voltage Vavg23 corresponding to real-time battery level Q3.

[0060] Specifically, the discharge mapping data is configured to determine the real-time battery charge based on the battery's discharge voltage. Optionally, during the discharge process, the atomizing device acquires the actual discharge voltage and discharge mapping data of its battery, and determines the real-time charge corresponding to the actual discharge voltage based on the discharge mapping data, thereby obtaining the actual discharge charge of the battery and accurately confirming the actual discharge status of the battery.

[0061] In some embodiments, discharge mapping data can be recorded in the form of lookup tables, matrices, or fitted curves. For example, discharge mapping data can be recorded in the form of a lookup table to obtain a battery charge-discharge voltage mapping table. During the discharge process, the atomizing device can obtain the actual discharge voltage of the battery and determine the actual discharge charge by querying the battery charge-discharge voltage mapping table, thus accurately confirming the actual discharge status of the battery. Furthermore, the atomizing device can also display the determined battery discharge charge in real time during the discharge process, allowing users to accurately understand the battery's discharge status and improving the reliability and user experience of the atomizing device.

[0062] In some embodiments of this application, such as Figure 3 As shown, before performing alternating charge and discharge treatment on the battery in step 101, the battery testing method further includes: Step 301: Obtain the initial state of the battery before the alternating charge and discharge process.

[0063] In this embodiment of the application, the initial state of the battery can be obtained before performing alternating charge and discharge processing. The initial state at least indicates the current battery charge level. Optionally, the initial state includes at least the battery's initial charge level or the battery's initial voltage.

[0064] In some embodiments, obtaining the initial state includes detecting the current voltage value of the battery or detecting the initial charge level of the battery. The initial state may also include parameters such as battery temperature and health status.

[0065] Step 302: When the initial state indicates that the initial charge of the battery is lower than the rated charge threshold, the battery is subjected to alternating charge and discharge treatment.

[0066] In this embodiment, after obtaining the initial state of the battery before the alternating charge-discharge process, it can be determined whether the initial state indicates that the battery's initial charge level is lower than the rated charge threshold, thereby determining whether the battery is currently in an optimal state for collecting charging mapping data and / or discharging mapping data. It is easy to understand that the lower the initial charge level of the battery, the more rounds of charging and discharging can be performed during the alternating charge-discharge process, thus allowing for the collection of more average charging voltage and average discharging voltage values ​​corresponding to the actual charge level of the battery, resulting in richer charging and discharging mapping data. Clearly, a battery in an optimal data collection state can be understood as having a lower initial charge level.

[0067] Therefore, if the initial state indicates that the battery's initial charge level is below the rated charge threshold, it indicates that the battery is currently in an optimal state for acquiring charging and / or discharging mapping data, and alternating charging and discharging processing can begin. Conversely, if the initial state indicates that the battery's initial charge level is not below the rated charge threshold, it indicates that the battery is not currently in an optimal state for acquiring charging and / or discharging mapping data, and alternating charging and discharging processing can be avoided.

[0068] In an optional embodiment, the initial state includes the battery's initial voltage. The initial state indicates that the battery's initial charge level is below a rated charge threshold, including an initial voltage within a target voltage range. This target voltage range is the range of voltages the battery can withstand when its charge level is below the rated charge threshold.

[0069] Optionally, step 301, obtaining the initial state of the battery before the alternating charge-discharge treatment, includes obtaining the initial voltage of the battery before starting the alternating charge-discharge treatment. Step 302, when the initial state indicates that the initial charge of the battery is lower than the rated charge threshold, starting the alternating charge-discharge treatment of the battery includes starting the alternating charge-discharge treatment of the battery when the initial voltage is within the target voltage range.

[0070] Specifically, a target voltage range can be preset, which is the voltage range of the battery when its charge level is below the rated charge threshold. After obtaining the initial voltage of the battery before alternating charge-discharge processing, it can be determined whether the initial voltage is within the target voltage range to determine whether the battery is currently in an optimal state for acquiring charge mapping data and / or discharge mapping data. If the initial voltage is within the target voltage range, it indicates that the battery is currently in an optimal state for acquiring charge mapping data and / or discharge mapping data, and alternating charge-discharge processing can begin. Conversely, if the initial voltage is not within the target voltage range, it indicates that the battery is not currently in an optimal state for acquiring charge mapping data and / or discharge mapping data, and alternating charge-discharge processing can be omitted. For example, the rated charge threshold can be in the range of [10%, 20%]. Correspondingly, the target voltage range can be [0, 3.2]V.

[0071] In another optional case, the initial state includes the battery's initial charge level. Correspondingly, step 301, which involves obtaining the battery's initial state before the alternating charge-discharge process, includes: obtaining the battery's initial charge level before the alternating charge-discharge process begins.

[0072] Specifically, a preset rated capacity threshold can be used. After obtaining the initial capacity of the battery before alternating charge and discharge processing, it can be determined whether the initial capacity is less than the rated capacity threshold to determine whether the battery is currently in an optimal state for acquiring charging mapping data and / or discharging mapping data. If the initial capacity is less than the rated capacity threshold, it indicates that the battery is currently in an optimal state for acquiring charging mapping data and / or discharging mapping data, and alternating charge and discharge processing can begin. Conversely, if the initial capacity is greater than or equal to the rated capacity threshold, it indicates that the battery is not currently in an optimal state for acquiring charging mapping data and / or discharging mapping data, and alternating charge and discharge processing can be omitted. For example, the rated capacity threshold can be set to [10%, 20%].

[0073] In this optional embodiment, by acquiring the initial state of the battery before the alternating charge and discharge process, and starting the alternating charge and discharge process when the initial state indicates that the initial charge of the battery is lower than the rated charge threshold, it is possible to start the alternating charge and discharge process when the battery charge is low, so as to perform more rounds of charge and discharge process on the battery. This allows for the collection of more average charging voltage and average discharging voltage corresponding to the actual charge of the battery, resulting in richer and more complete charging and discharging mapping data, effectively avoiding the problem of low data integrity caused by the initial charge of the battery being too high.

[0074] In some embodiments of this application, such as Figure 4As shown, step 103, which obtains the average charging voltage corresponding to the real-time charge based on multiple first real-time voltages, includes: Step 1031: Obtain the first real-time voltage within a first time period from a plurality of first real-time voltages to obtain a plurality of first target voltages. The first time period is the n seconds before the battery charging stops, where n is a positive integer.

[0075] Step 1032: Obtain the average charging voltage corresponding to the real-time power level based on multiple first target voltages.

[0076] In this embodiment of the application, during the alternating charge-discharge process of the battery, for each charging process, multiple first real-time voltages can be obtained within the first n seconds before charging stops, resulting in multiple first target voltages, thus obtaining multiple first target voltages corresponding to each charging process. Here, n is a positive integer, and its value can be configured according to the battery characteristics, ensuring that a stable voltage value of the battery can be obtained. Optionally, n can be 1, 2, or 3, etc. For example, if n is 1, the first time period is the first 1 second before charging stops.

[0077] Optionally, the process of obtaining the average charging voltage corresponding to the real-time charge level based on multiple first target voltages can include calculating the average of the multiple first target voltages to obtain the average charging voltage corresponding to the real-time charge level. Specifically, for each charging process, the average of the multiple first target voltages of the battery during that charging process can be calculated to obtain the average charging voltage. This average charging voltage can be considered as the battery voltage after that charging process, which corresponds to the real-time charge level of the battery after that charging process. Similarly, based on the multiple first target voltages of the battery during each charging process, the average charging voltage corresponding to the real-time charge level of the battery after each charging process can be obtained.

[0078] During the period before charging stops, the charging current to the battery is typically constant. Although the battery voltage hasn't reached stability, its fluctuations are relatively gradual. This minimizes the impact of instantaneous voltage fluctuations and noise interference on the real-time voltage data, effectively indicating the battery voltage at the point of charging stop. Therefore, selecting the average real-time voltage within the first time period effectively filters out random interference, yielding an accurate representation of the battery's actual voltage after charging—the voltage at the point of charging stop—which precisely corresponds to the battery's remaining charge. Clearly, utilizing the real-time voltage within the first time period of each charging cycle provides highly accurate charging mapping data, avoiding errors caused by sampling interference.

[0079] In some embodiments of this application, such as Figure 5As shown, step 202, which obtains the average discharge voltage corresponding to the charge based on multiple second real-time voltages, includes: Step 2021: Obtain the second real-time voltage within the second time period from multiple second real-time voltages to obtain multiple second target voltages. The second time period is m seconds after the target duration of stopping battery charging.

[0080] Step 2022: Obtain the average discharge voltage corresponding to the real-time charge based on multiple second target voltages.

[0081] In some embodiments of this application, discharging the battery can also refer to a resting process after stopping battery charging, used to simulate the battery's discharge process. In alternating charge-discharge processing of the battery, for each resting process (discharge process), multiple second real-time voltages can be acquired within m seconds after the target duration of charging cessation, to obtain multiple second target voltages corresponding to each resting process. Here, m is a positive integer, and its value can be configured according to battery characteristics, ensuring a stable battery voltage value can be obtained. Optionally, m can be 1, 2, or 3, etc. The target duration represents the waiting time from stopping charging to starting to acquire the second target voltage. By setting this target duration, it can be ensured that the battery voltage transitions from the charging state to the resting state before acquiring the accurate second target voltage, thereby ensuring that the second target voltage can effectively represent the battery voltage at the beginning of the battery discharge process. The value of this target duration can be configured according to battery characteristics. Optionally, the target duration can be 500 milliseconds, 800 milliseconds, or 1 second.

[0082] Optionally, the process of obtaining the average discharge voltage corresponding to the real-time charge based on multiple second target voltages can include calculating the average of multiple second target voltages to obtain the average discharge voltage corresponding to the real-time charge. Specifically, for each resting process, the average of multiple second target voltages of the battery during that resting process can be calculated to obtain the average discharge voltage. This average discharge voltage can be considered as the battery voltage at the beginning of the battery discharge process, which corresponds to the real-time charge of the battery after that charging process (i.e., at the beginning of the battery discharge process). Similarly, based on the multiple second target voltages of the battery during each resting process, the average charging voltage corresponding to the real-time charge of the battery after each charging process can be obtained.

[0083] Because the charging current gradually decreases to zero and the battery voltage stabilizes after charging stops, the real-time battery voltage data acquired during this period is minimally affected by instantaneous voltage fluctuations and noise interference, effectively representing the battery voltage at the initial stage of discharge. Therefore, selecting the average real-time voltage data within the second time period effectively filters out random interference, ensuring an accurate representation of the battery voltage at the initial stage of discharge and its precise correspondence with the initial battery charge level. Clearly, utilizing the real-time voltage within the second time period during each static processing step yields highly accurate discharge mapping data, avoiding errors caused by sampling interference.

[0084] In some embodiments of this application, before performing alternating charge and discharge processing on the battery in step 101, the battery detection method further includes: determining whether the battery is a battery being charged for the first time, so as to start performing alternating charge and discharge processing on the battery if the battery is a battery being charged for the first time.

[0085] Since the collection of battery charging and discharging mapping data depends on charging and discharging the battery, batteries that have been charged typically already have their charging and discharging mapping data collected. Therefore, by determining whether a battery has been charged, it is possible to determine whether charging and discharging mapping data has already been collected for that battery, thereby avoiding the need for repeated collection of battery charging and discharging mapping data.

[0086] Optionally, before performing alternating charge-discharge processing on the battery, it can be determined whether the battery is being charged for the first time, to ascertain whether its charge mapping data and discharge mapping data have been collected before. If the battery is being charged for the first time, indicating that its charge mapping data and discharge mapping data have not been collected before, alternating charge-discharge processing can begin to obtain the battery's charge mapping data and discharge mapping data. If it is determined that the battery is not being charged for the first time, indicating that its charge mapping data and discharge mapping data have already been collected, alternating charge-discharge processing can be omitted to collect the battery's charge mapping data and discharge mapping data. In this embodiment, by determining whether the battery has been charged before, it is determined whether charge mapping data and discharge mapping data have been collected for that battery, thereby avoiding the repeated collection of the battery's charge mapping data and discharge mapping data.

[0087] In some embodiments of this application, the battery detection method further includes controlling the battery to stop charging when charging stop conditions are met. These charging stop conditions include: the battery's real-time charge level reaching a calibrated charge level, or the battery having been charged more than a target number of times.

[0088] In this embodiment, the charging stop condition is used to limit the timing of stopping the alternating charge-discharge process of the battery. Optionally, after performing one alternating charge-discharge process on the battery, it can be determined whether the battery meets the charging stop condition, so that if the charging stop condition is met, the battery is controlled to stop charging; if the charging stop condition is not met, the next alternating charge-discharge process continues.

[0089] The conditions for stopping charging include: the battery's charge reaching the rated charge level, or the number of charging cycles exceeding the target number. Optionally, the rated charge level can be the battery's charge level when fully charged, such as 100%. That is, when the battery's charge level reaches the rated charge level, it indicates that the battery has reached its full charge state. Alternatively, the rated charge level can be any other preset charge level, the value of which can be set according to actual needs. The target number can be the maximum allowable number of alternating charge-discharge cycles for the battery. In practical applications, the target number can be determined based on the battery's rated charge level, initial charge level, and rated charge level. For example, target number = (rated charge level - initial charge level) / rated charge level. In some embodiments, the target number is set based on the maximum allowable number of charge-discharge cycles.

[0090] For example, the charging stop condition includes the battery's charging cycles exceeding a target number. After one alternating charge-discharge cycle, it can be determined whether the number of charging cycles is less than the target number. If the number of charging cycles is greater than or equal to the target number, indicating that the battery has reached full charge, the alternating charge-discharge cycle is stopped. If the number of charging cycles is less than the target number, indicating that the battery has not reached full charge, the alternating charge-discharge cycle continues. In this embodiment, by adding a charging stop condition, charging can be stopped when the battery reaches full charge, ensuring the integrity of charging and discharging mapping data while effectively preventing overcharging and protecting battery safety and lifespan.

[0091] In this embodiment, the battery is subjected to alternating charge-discharge processing, configured to charge the battery with its rated capacity in a single charge. Multiple first real-time voltages are acquired after each charge. Based on the battery's initial capacity, the rated capacity charged in a single charge, and the number of charges, the battery's real-time capacity at the end of each charge is calculated. The average of these multiple first real-time voltages during that charge is then calculated, yielding the average charging voltage corresponding to a given real-time capacity. This process continues, providing an accurate mapping between the battery's multiple real-time capacities and the average charging voltage, resulting in charging mapping data. Since the real-time capacity corresponding to each average charging voltage is an accurate value calculated based on the battery's initial capacity, the rated capacity charged in a single charge, and the number of charges, rather than relying on manual estimation or theoretical curves, data errors introduced by differences in human experience or mismatched external testing environments are avoided. This effectively ensures the accuracy of the battery voltage-capacity mapping relationship in the charging mapping data. Furthermore, since the battery detection method provided in this application can be directly applied to actual devices to directly obtain charging mapping data of the actual devices, the battery voltage and capacity mapping relationship recorded in the charging mapping data matches the device environment. Compared with related technologies, this application can effectively eliminate the error in the battery voltage and capacity mapping relationship caused by the mismatch between the capacity distribution cabinet environment and the device environment, further ensuring the accuracy of the battery voltage and capacity mapping relationship.

[0092] To facilitate understanding of the technical solution of this application, the following two examples further illustrate the battery detection method provided in the embodiments of this application. In these examples, the battery detection method is executed by a controller in an atomizing device.

[0093] For example, such as Figure 6 As shown, the battery detection method includes: when the battery starts charging, the controller determines whether the battery in the atomizing device is being charged for the first time. If it is not the first charge, the battery is charged normally. If it is the first charge, the controller acquires the battery's initial voltage (initial state) and determines whether the initial voltage is within the target voltage range, i.e., (3.15V, 3.25V). Therefore, if the initial voltage is within the target voltage range, the controller can control the host computer to begin alternating charge and discharge processing of the battery in the atomizing device; if the initial voltage is not within the target voltage range, an alarm can be issued to suggest pausing charging of the atomizing device to consume its power, facilitating the collection of battery charging and discharging mapping data. The alternating charge and discharge processing is configured to charge the battery with 10 mA (rated capacity) per charge.

[0094] During the alternating charge and discharge process, the battery voltage is recorded in real time to obtain multiple initial actual voltages during charging. Furthermore, it is determined whether the battery has received 10 mA of charge to decide whether to stop charging. If the battery has not received 10 mA of charge, charging continues while the battery voltage is recorded in real time.

[0095] Once the battery has been charged to 10 mA, charging is stopped. The controller calculates the battery's real-time charge level after the initial 10 mA charge and the average battery voltage during the first second (the first time period) before charging is stopped, thus obtaining the average charging voltage corresponding to the current real-time charge level. Furthermore, the controller calculates the average battery voltage during the second time period (800 milliseconds after charging stops), thus obtaining the average discharging voltage corresponding to the current real-time charge level.

[0096] The controller determines whether the battery's actual charge level has reached the calibrated charge level. If the battery's actual charge level has reached the calibrated charge level, it establishes charging mapping data based on the battery's real-time charge level and the corresponding average charging voltage, and establishes discharging mapping data based on the battery's real-time charge level and the corresponding average discharging voltage. Current detection ends, and the battery begins normal charging. If the battery's actual charge level has not reached the calibrated charge level, it determines whether to recharge the battery. If the battery is recharged, it performs alternating charge and discharge cycles, and the charging count is incremented by one. If the battery is not recharged, current detection ends, and the battery begins normal charging.

[0097] In this application example, by performing alternating charge and discharge processing on the battery, the charging voltage and discharging voltage of the battery at the same charge level can be obtained, and the battery charging mapping data and discharging mapping data can be established. These data are used by the atomizing device to determine the charging amount corresponding to the actual charging voltage during actual charging, and to determine the discharging amount corresponding to the actual discharging voltage during actual discharging, thereby ensuring the accuracy of the determined battery charge level.

[0098] Furthermore, in atomizing devices, a battery detection method is implemented on the printed circuit board assembly (PCBA) of the actual project to record and learn the battery's charge and discharge data. This generates charge and discharge mapping data that perfectly matches the specific hardware combination, and produces charge and discharge curves that record this data. This effectively avoids the problem of inaccurate battery capacity confirmation due to hardware differences. The specific hardware combination includes: a specific battery, a specific charging chip, and a specific printed circuit board (PCB) layout.

[0099] In another example, the battery detection method provided in this application embodiment is implemented jointly by a host computer and an atomizing device. The host computer, under the control of the controller, can perform alternating charge and discharge processing on the battery. The specific method steps are as follows: Figure 7 As shown.

[0100] After detecting the connection between the host computer and the atomizing device, the controller in the atomizing device can prompt the technician to start charging the battery by clicking on the host computer. The controller resets the accumulated charge level of the battery to zero. During the charging process, it acquires the battery charging current in real time, counts the charging time, and calculates the amount of electricity charged into the battery based on the charging current and charging time to obtain the accumulated charge level, and determines whether the accumulated charge level has reached the rated capacity (10mAh). If the accumulated charge level has not reached the rated capacity, it returns to acquiring the battery charging current in real time; if the accumulated charge level has reached the rated capacity, it controls the host computer to stop charging the battery for 2 seconds, and then controls the host computer to resume charging the battery after 2 seconds of cessation. The controller resets the accumulated charge level of the battery to zero, and so on, until the controller determines that the actual battery capacity has reached the calibrated capacity, and then controls the host computer to stop the alternating charging and discharging of the battery. It should be noted that the duration of the charging stop needs to be greater than the sum of the target time and the second time period.

[0101] In summary, the battery testing method provided in this application performs alternating charge and discharge treatment on the battery, and calculates the average charging voltage corresponding to the real-time battery capacity after each fixed rated charge, achieving an accurate one-to-one mapping between the real-time battery capacity and the average charging voltage. Since the real-time battery capacity corresponding to each average charging voltage is an accurate value calculated using a formula based on the initial capacity, rated capacity, and number of charge cycles, rather than relying on manual estimation or external theoretical curves, it avoids mapping errors introduced by differences in human experience, subjective calculations, and mismatches in the external testing environment, ensuring the accuracy of the established battery voltage-capacity mapping relationship. Furthermore, since the battery testing method provided in this application can be directly applied to atomizing devices, directly acquiring the battery capacity and voltage within the atomizing device, the obtained battery capacity-voltage correspondence matches the device environment. Compared to related technologies, this application effectively eliminates errors in the voltage-capacity mapping relationship caused by mismatches between the capacity testing cabinet environment and the device environment, further ensuring the accuracy of the battery voltage-capacity mapping relationship.

[0109] It should be noted that the establishment of discharge mapping data can be referred to the relevant descriptions in the foregoing embodiments, and will not be repeated in this application embodiment.

[0110] In summary, the battery power calibration method provided in this application can determine the charging capacity corresponding to the actual charging voltage of the battery based on accurate battery charging mapping data during the charging process of the atomizing device, so as to accurately reflect the actual charging status of the battery. Similarly, during the discharging process of the atomizing device, it can determine the discharging capacity corresponding to the actual discharging voltage of the battery based on accurate battery discharging mapping data, so as to accurately reflect the actual discharging status of the battery.
