Description

Technical Field

[0001] This application relates to the field of electrical control technology for atomizing devices, and in particular to a method for dynamic compensation of power supply voltage and an atomizing device. Background Technology

[0002] Atomizing devices use batteries to power the atomizer core, which heats the atomizing liquid to produce an aerosol. Key performance indicators include consistent flavor across the entire battery range, uniformity of puff count, and stable battery life. Currently, atomizing devices typically use a fixed factory-calibrated voltage-state-charge (SOC) table to estimate remaining battery power. This method fails to account for individual differences between batches of batteries, capacity decay after battery cycling, and internal resistance variations under high and low temperatures. This results in significant SOC estimation errors, frequently leading to inaccurate battery display, premature device locking, or battery damage from over-discharge.

[0003] The atomizing device operates in a high-current pulse discharge mode, with a large current during a single inhalation. This results in a significant voltage drop across the battery's internal resistance and electrochemical polarization. After inhalation stops, the battery voltage requires a certain amount of time to recover and stabilize. Current technology does not fully consider the impact of inhalation parameters on voltage response, leading to deviations in the collected voltage data and an inability to accurately reflect the battery's true condition.

[0004] If a fixed power output and puff allocation strategy is adopted, the power consumption will be too fast in the high voltage range and the power will be insufficient in the low voltage range, resulting in obvious differences in taste across the entire power range. Furthermore, it is easy to experience voltage jumps, sudden drops in atomization volume, or even interruption of inhalation in the low power range.

[0005] Different batches of batteries have inherent differences in capacity, internal resistance, and open circuit voltage (OCV) characteristics. Existing technology requires individual programming of different parameters into the battery's electronic control unit, which increases production costs and management difficulty, and cannot adapt to changes in characteristics caused by battery aging during use.

[0006] Therefore, there is an urgent need for a power control method that can dynamically compensate for power supply voltage, accurately estimate remaining power, adapt to differences in battery characteristics, and ensure uniform number of outlets and consistent taste across the entire power range. Summary of the Invention

[0007] Therefore, it is necessary to provide a power supply voltage dynamic compensation method and atomizing device that can dynamically compensate for power supply voltage, accurately estimate remaining power, adapt to differences in battery characteristics, and ensure uniform puff count and consistent taste across the entire power range, in order to address the aforementioned technical problems.

[0008] In a first aspect, this application provides a dynamic power supply voltage compensation method applied to an atomizing device, the atomizing device including a power supply module and a trigger module, the method comprising:

[0009] After receiving the adjacent trigger signal and end signal emitted by the trigger module, the initial parameters of the discharge process of the atomizing device between the emission of the trigger signal and the end signal are obtained.

[0010] Establish a mapping relationship between the initial parameters and the voltage response parameters of the power supply module;

[0011] Based on the mapping relationship and the constraints of the voltage response parameters, the target parameters are obtained;

[0012] The initial parameters are replaced with the target parameters to achieve dynamic compensation of the voltage of the power module;

[0013] The initial parameters include any one or more of power, suction duration, suction interval, and temperature; the voltage response parameters include any one or more of voltage recovery rate, voltage stability value, and voltage fluctuation amplitude.

[0014] By constructing a mapping relationship between multivariate parameters such as power, pumping duration, pumping interval, and temperature and voltage recovery rate, stable value, and fluctuation amplitude, the voltage response under different pumping parameters can be accurately predicted. Based on the constraints of the voltage response parameters, the target parameters can be adjusted to achieve dynamic compensation of the power supply voltage, thereby ensuring the accuracy of voltage acquisition. This allows the SOC estimation error to be controlled within the expected range while ensuring a consistent experience across all power levels, avoiding issues such as inaccurate power display and premature power lock-up.

[0015] Furthermore, the constraints include:

[0028] Based on the iterated test parameters, the test parameter in the test parameter-voltage response parameter combination is obtained as the target parameter.

[0029] Furthermore, the method also includes:

[0031] Multiple discharge port numbers are obtained based on the multiple power ranges, wherein each discharge port number corresponds to one of the power ranges;

[0032] After receiving the adjacent trigger signal and the end signal issued by the trigger module, the cumulative discharge capacity of the power module is obtained.

[0033] Obtain the voltage of the power module;

[0034] The remaining capacity is calculated based on the discharge capacity and the total capacity of the power module, and compared with a preset voltage lookup table to obtain the standard voltage of the power module.

[0035] The number of discharge ports is adjusted based on the voltage of the power module and the standard voltage.

[0036] The preset voltage lookup table includes a remaining capacity-standard voltage combination, and the corresponding standard voltage can be obtained based on the remaining capacity.

[0037] Furthermore, the step of correcting the number of discharge ports based on the voltage of the power module and the standard voltage specifically includes:

[0038] If the voltage of the power module is greater than the standard voltage, the number of discharge ports in the current power range is reduced, and the quota of the reduced number of discharge ports is allocated to subsequent power ranges.

[0039] If the voltage of the power module is less than the standard voltage, the number of discharge ports in the current power range is increased, and the quota for the increased number of discharge ports comes from the previous power range.

[0040] Furthermore, the method also includes:

[0041] If the voltage of the power module is less than the warning voltage threshold, the corrected capacity is calculated based on the remaining capacity corresponding to the voltage of the power module and the remaining capacity corresponding to the standard voltage.

[0042] The number of discharge ports is adjusted based on the corrected capacity and the remaining capacity corresponding to the voltage of the power module.

[0043] Furthermore, the method also includes:

[0044] The target parameters are adjusted based on the discharge capacity, the total capacity of the power module, and the preset voltage lookup table, according to a complete charge-discharge cycle.

[0045] Furthermore, the atomizing device also includes a charging module. The step of obtaining the total capacity of the power module and dividing the power into multiple power ranges based on the total capacity of the power module specifically includes:

[0065] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0066] It should be noted that the terms "first," "second," etc., used in this application can be used to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish the first element from the second element. The terms "comprising" and "having," and any variations thereof, used in this application, are intended to cover non-exclusive inclusion. The term "multiple" used in this application refers to two or more. The term "and / or" used in this application refers to one of the embodiments, or any combination of multiple embodiments.

[0067] This application provides a dynamic power supply voltage compensation method, applied to atomizing device 1. Please refer to the following: Figure 1 and Figure 2 , Figure 1 A schematic diagram of the frame of the atomizing device 1 provided in one embodiment of this application; Figure 2 This is a schematic flowchart of a power supply voltage dynamic compensation method according to another embodiment of this application. The atomizing device 1 includes a power module 11 and a trigger module 12, and the method includes:

[0068] S201, after obtaining the adjacent trigger signal and end signal emitted by the trigger module, obtain the initial parameters of the discharge process of the atomizing device between the emission of the trigger signal and the end signal;

[0069] S202, establish the mapping relationship between the initial parameters and the voltage response parameters of the power supply module;

[0070] S203, Obtain the target parameters according to the mapping relationship and the constraints of the voltage response parameters;

[0071] S204, Replace the initial parameters with the target parameters to achieve dynamic compensation of the voltage of the power module;

[0072] The initial parameters include any one or more of power, suction duration, suction interval, and temperature; the voltage response parameters include any one or more of voltage recovery rate, voltage stability value, and voltage fluctuation amplitude.

[0073] It should be noted that the atomizing device 1 is a portable electronic device that is powered by an electric power source and electrically controlled to heat the atomizing core, atomizing the atomizing liquid into an aerosol for the user to inhale. Specifically, in this embodiment, the atomizing device 1 is an electronic cigarette, the trigger module 12 is a microphone, and the power module 11 is a battery. In other possible embodiments, the atomizing device 1, the trigger module 12, and the power module 11 can also be other specific devices or electronic components, and this application does not limit them.

[0074] Understandably, when a user uses the atomizing device 1, the trigger module 12 sends a trigger signal when the user makes an inhalation motion; and sends an end signal when the user's inhalation motion ends. In other words, by acquiring adjacent trigger and end signals from the trigger module 12, the duration of one inhalation motion, i.e., the inhalation duration, can be obtained. The accumulated time interval between acquiring the end signal and then acquiring the trigger signal again is the time interval between two adjacent inhalation motions, i.e., the inhalation interval.

[0075] In this embodiment, such as Figure 1 As shown, the atomizing device 1 also includes a processing module 13 and a discharge module 14. After receiving the trigger signal from the trigger module 12, the processing module 13 will control the power module 11 to transmit electrical energy to the discharge module 14. The processing module 13 is also used to configure the power output of the discharge module 14.

[0076] It is understandable that the impact of the discharge module 14 outputting at different power levels on the voltage response parameters of the power module 11 is different. For example, under the same pumping duration and pumping interval, when the discharge module 14 outputs at a higher power, the power module 11 needs to transfer more electrical energy to the discharge module 14, and the voltage of the power module 11 is more difficult to recover to a stable state. Therefore, the SOC estimation of the power module 11 will produce errors.

[0077] Similarly, when the discharge module 14 outputs the same power, a longer suction time or a shorter suction interval requires the power module 11 to transfer more electrical energy to the discharge module 14, making it more difficult for the voltage of the power module 11 to return to a stable state. It should be noted that, please also refer to... Figure 3 , Figure 3 This is a schematic diagram of the voltage recovery curve of the power module 11 provided in another embodiment of this application. Typically, the OCV of the power module 11 is acquired again after a certain time (usually 120ms) following the acquisition of the termination signal to perform SOC estimation, ensuring that the voltage of the power module 11 has recovered to a stable state. Figure 3 As shown, the voltage of the power module after discharge rises from 3.7V to 3.75V after 120ms. However, users may perform multiple pumping actions in a short period of time, i.e., the pumping interval is short, making it difficult to accurately obtain the OCV of the power module 11, which will lead to errors in the SOC estimation of the power module 11.

[0078] In addition, ambient temperature also affects the voltage recovery of the power module 11. For example, excessively low or high temperatures will reduce the activity of the power module 11, resulting in a decrease in the efficiency of the power module 11 in transmitting electrical energy to the discharge module 14, and making it difficult for the voltage of the power module 11 to recover to a stable state.

[0079] Therefore, in this embodiment, the initial parameters are constructed by mapping one or more of power, suction duration, suction interval, and temperature to the voltage response parameters of the power module 11. Power, suction duration, suction interval, and temperature can all directly reflect the voltage response parameters. The voltage response parameters include one or more of voltage recovery rate, voltage stability value, and voltage fluctuation amplitude. The voltage recovery rate refers to the rate of voltage recovery of the power module 11 within a certain period after the control module controls the power module 11 to stop transmitting electrical energy to the discharge module 14 upon receiving the termination signal.

[0080] ,

[0081] in, The voltage recovery rate of the power module 11. To obtain the voltage of the power module 11 120ms after the end signal, In order to obtain the voltage of the power module 11 at the time of the termination signal, The duration is 120ms; the voltage stability value refers to the absolute value of the difference between the voltage of the power module 11 obtained after a certain period of time following the control module's control of the power module 11 to stop transmitting electrical energy to the discharge module 14, and the voltage of the power module 11 obtained during the most recent long-term (more than 2 hours) period of inactivity without power output.

[0082] ,

[0083] in, The voltage stability value of the power module 11, The voltage of the power module 11 during its most recent prolonged period of inactivity and no power output; the voltage fluctuation amplitude refers to the difference between the maximum peak value and the minimum peak value of the voltage of the power module 11 during the process of the control module controlling the power module 11 to transfer electrical energy to the discharge module 14, i.e.

[0084] ,

[0085] in, The voltage fluctuation amplitude of the power module 11 This refers to the maximum voltage peak value during the process of the power module 11 transmitting electrical energy to the discharge module 14. This refers to the minimum voltage peak value during the process of the power module 11 transmitting electrical energy to the discharge module 14.

[0086] It is understood that the voltage response parameters mentioned above can directly reflect the voltage recovery efficiency of the power module 11 after discharge, thereby reflecting whether there is a deviation between the voltage of the power module 11 obtained after discharge and the expected voltage. By constructing a mapping relationship between the initial parameters and the voltage response parameters, the influence of each initial parameter on the voltage response parameters can be quantified. Based on the mapping relationship and constraints set according to a preset optimization objective, target parameters can be obtained and used to replace the initial parameters, thereby achieving dynamic compensation for the voltage of the power module 11. This reduces the deviation between the obtained voltage of the power module 11 and the expected voltage, ultimately enabling accurate SOC estimation based on the obtained voltage of the power module 11.

[0087] It should be noted that the initial parameters and voltage response parameters mentioned above are parameters that can strongly reflect the influence on the voltage of the power module 11. For ease of understanding, this application only provides some illustrative examples of these parameters and does not imply that this application limits the categories of the initial parameters and voltage response parameters. Similarly, the certain time after obtaining the end signal, which is set to 120ms in this application, is also merely an example and does not imply that this application limits the value of this time.

[0088] It is understood that any method that uses this application to construct a mapping relationship between the initial parameters and the voltage response parameters of the power module 11; obtains the target parameters according to the mapping relationship and the constraints of the voltage response parameters; and replaces the initial parameters with the target parameters to achieve dynamic compensation of the voltage of the power module 11, falls within the protection scope of this application.

[0089] Understandably, in this embodiment, by constructing a mapping relationship between multi-variable parameters such as power, pumping duration, pumping interval, and temperature and voltage recovery rate, stable value, and fluctuation amplitude, the voltage response under different pumping parameters can be accurately predicted. Based on the constraints of the voltage response parameters, the target parameters are adjusted to achieve dynamic compensation of the power supply voltage, thereby ensuring the accuracy of voltage acquisition. This ensures a consistent experience across all power ranges while keeping the SOC estimation error within the expected range, avoiding issues such as inaccurate power display and premature power lock-up.

[0090] In one possible implementation, the constraints include:

[0091] The voltage recovery rate is greater than or equal to the recovery threshold;

[0092] And / or, the voltage stability value is less than or equal to the stability threshold;

[0093] And / or, the voltage fluctuation amplitude is less than or equal to the fluctuation threshold.

[0094] Specifically, in this embodiment, the recovery threshold can be set to 0.2mV / ms. It is understood that if the voltage recovery rate is less than the recovery threshold, it indicates that the electrochemical polarization of the power module 11 requires too long to subside. After the control module stops the power module 11 from transmitting power to the discharge module 14, the voltage of the power module 11 may still not reach a stable state after a certain period, leading to a significant deviation in the subsequent SOC estimation of the power module 11.

[0095] The stability threshold can be set to 0.4V. It is understood that if the stable voltage value is greater than the stability threshold, it indicates that the voltage of the power module 11 obtained after a certain period of time following the control module's control of the power module 11 to stop transmitting power to the discharge module 14 deviates significantly from the voltage obtained during the most recent long period of inactivity without power output. In this case, directly using the voltage of the power module 11 will also lead to a significant deviation in the subsequent SOC estimation of the power module 11.

[0096] The fluctuation threshold can be set to 50mV. If the voltage fluctuation amplitude of the power module 11 exceeds the fluctuation threshold during a single suction and discharge process, it will cause the output power of the discharge module 14 to be unstable, resulting in user experience problems such as fluctuating taste and sudden changes in atomization volume. Furthermore, if the voltage fluctuation amplitude is greater than the fluctuation threshold, it indicates that the single discharge pressure of the power module 11 is too high, and it cannot achieve a stable voltage recovery after discharge. This will also lead to a significant deviation in the subsequent SOC estimation of the power module 11.

[0097] Therefore, in this embodiment, by obtaining the target parameters and dynamically compensating the voltage of the power module 11 according to the mapping relationship and the constraint conditions, the voltage recovery rate can be greater than or equal to the recovery threshold, and / or the voltage stability value can be less than or equal to the stability threshold, and / or the voltage fluctuation amplitude can be less than or equal to the fluctuation threshold, thereby improving the accuracy of the subsequent SOC estimation of the power module 11.

[0098] It should be noted that, in this embodiment, the three constraints described above can be applied individually or in any combination. In other possible embodiments, the constraints may also include other different conditions, which are not limited herein. Furthermore, in practical applications, the constraints can be adjusted according to different usage scenarios.

[0099] In one possible implementation, please refer to [the relevant documentation / reference]. Figure 4 , Figure 4 This is a schematic diagram illustrating the process of constructing a mapping relationship according to another embodiment of this application. The step of constructing the mapping relationship between the initial parameters and the voltage response parameters of the power module 11 specifically includes:

[0100] S401, Divide the test intervals according to the initial parameters;

[0101] S402, within a single test interval, take multiple test parameters, obtain the voltage response parameters corresponding to the test parameters, and generate a test parameter-voltage response parameter combination;

[0102] The step of obtaining the target parameters based on the mapping relationship and the constraints of the voltage response parameters specifically includes:

[0103] S403, based on the constraints, obtain the test parameter in the test parameter-voltage response parameter combination as the target parameter.

[0104] Specifically, in this embodiment, when constructing the mapping relationship between the initial parameters and the voltage response parameters, multiple test intervals are first divided according to the reasonable operating range of each initial parameter. For example, the power parameter can be divided into three test intervals: 10W-25W, 25W-40W, and 40W-50W, covering low, medium, and high power levels, corresponding to different load demand scenarios; the suction duration parameter can be divided into three test intervals: 0.5s-2s, 2s-3.5s, and 3.5s-5s, respectively matching the user's short, medium, and long suction behaviors; the suction interval parameter can be divided into three test intervals: 0.5s-10s, 10s-20s, and 20s-30s, respectively matching the user's short, medium, and long time interval modes; and the temperature parameter can be divided into three test intervals: -10℃-20℃, 20℃-30℃, and 30℃-45℃, covering low temperature, normal temperature, and high temperature environmental conditions. It is understood that in other possible implementations, the number of test intervals and the specific values ​​of the initial parameters can be chosen in other ways, and this application does not limit them here.

[0105] In this embodiment, multiple test parameters can be obtained within the test interval using an equidistant or orthogonal experimental method, and actual tests can be performed based on these test parameters to obtain the voltage response parameters corresponding to the test parameters, thus generating a test parameter-voltage response parameter combination. For example, when the test parameters include a power of 25W, a suction duration of 2s, a suction interval of 10s, and a temperature of 25°C, the corresponding voltage response parameters can be obtained, forming a set of test parameter-voltage response parameter combinations. When the power is changed to 30W, while the suction duration, suction interval, and temperature parameters remain unchanged, corresponding voltage response parameters different from the previous set of test parameter-voltage response parameter combinations can be obtained, thus forming a new set of test parameter-voltage response parameter combinations. It can be understood that by obtaining multiple sets of test parameter-voltage response parameter combinations, different voltage response parameters of the atomizing device 1 under different test parameters can be obtained, that is, this application constructs a mapping relationship between the initial parameters and the voltage response parameters of the power module 11.

[0106] Furthermore, based on the mapping relationship, the voltage response parameter corresponding to the initial parameter can be predicted. If the predicted voltage response parameter satisfies the constraint condition, then the initial parameter is the target parameter; if the predicted voltage response parameter does not satisfy the constraint condition, the initial parameter can be compensated based on the test parameter that satisfies the constraint condition to obtain the target parameter, thereby achieving dynamic compensation of the voltage of the power module 11, thus improving the accuracy of the SOC estimation of the power module 11 while minimizing the impact on user experience.

[0107] In one possible implementation, please refer to [the relevant documentation / reference]. Figure 5 , Figure 5 A schematic diagram of the test parameter iteration process provided for another embodiment of this application. The method further includes:

[0108] S501, Obtain the voltage of the power module;

[0109] S502, Based on the voltage of the power module, construct the influence weights of the test parameters on the voltage response parameters;

[0110] S503, iterate the corresponding test parameters according to the constraints and the influence weights;

[0111] S504, based on the iterated test parameters, obtain the test parameter in the test parameter-voltage response parameter combination as the target parameter.

[0112] Specifically, in this embodiment, by comparing the difference between the voltage of the power module 11 acquired in real time and the voltage predicted based on the combination of test parameters and voltage response parameters, a formula for iterative compensation of the test parameters can be fitted, that is, the influence weight of each test parameter on the voltage response parameter can be constructed. For example, the compensation formula for the test parameter being power is as follows:

[0113] ,

[0114] in, The power parameter is calculated after weighting, where 0.04 is the influence constant coefficient and 0.01 is the influence weight of power on the voltage response parameter. The power parameters before iteration. It is a logarithmic function;

[0115] The compensation formula for the test parameter being the aspiration duration is as follows:

[0116] ,

[0117] in, The pumping time parameter is calculated after weighting, where 0.02 represents the weight of the pumping time on the voltage response parameter. The power parameters are those before iteration;

[0118] The compensation formula for the test parameter being the suction interval is as follows:

[0119] ,

[0120] in, The compensation formula for the test parameter being temperature is: where, The pumping interval parameter is calculated after weighting, where 0.5 represents the weight of the pumping interval's influence on the voltage response parameter. The suction interval parameter before iteration. It is an exponential function. The specific meaning of this formula is that when the suction interval before the iteration is less than 30 seconds, the suction interval before the iteration is adjusted according to... Perform iterations; if the suction interval before iteration is greater than or equal to 30s, then do not iterate on the suction interval parameter.

[0121] It should be noted that the iterative formulas for the above parameters are all based on the specific test results of the power module 11, that is, the difference between the voltage of the power module 11 obtained in real time and the voltage predicted according to the combination of test parameters and voltage response parameters, and the compensation formula obtained by fitting the difference. This application does not limit the specific compensation formula of the test parameters, the value of the influence weight, etc.

[0122] It is understood that, in this embodiment, iterating the test parameters according to the influence weight can quickly converge to the test parameters that satisfy the constraints with the fewest number of adjustments, ensuring the real-time performance of the control while minimizing the impact on the user's suction experience.

[0123] In one possible implementation, please refer to [the relevant documentation / reference]. Figure 6 , Figure 6 A schematic diagram illustrating the capacity range division process of a power module 11 provided in another embodiment of this application. The method further includes:

[0124] S601, Obtain the total capacity of the power module, and divide the power module into multiple power ranges according to the total capacity of the power module;

[0125] S602, obtain multiple discharge port numbers according to the multiple power ranges, wherein each discharge port number corresponds to one power range;

[0126] S603, after obtaining the adjacent trigger signal and the end signal issued by the trigger module, obtain the cumulative discharge capacity of the power module.

[0127] S604, Obtain the voltage of the power module;

[0128] S605, calculate the remaining capacity based on the discharge capacity and the total capacity of the power module, and compare it with a preset voltage lookup table to obtain the standard voltage of the power module;

[0129] S606, adjust the number of discharge ports according to the voltage of the power module and the standard voltage;

[0130] The preset voltage lookup table includes a remaining capacity-standard voltage combination, and the corresponding standard voltage can be obtained based on the remaining capacity.

[0131] Specifically, please refer to the following in this embodiment: Figure 7 , Figure 7 This is a schematic diagram illustrating the division of power ranges according to another embodiment of this application. An example is given where the total capacity of the power module 11 is divided into 10 consecutive power ranges. Figure 7 As shown, the total capacity of the power module 11 is 300mAh, so the capacity of each power range is 30mAh. The discharge capacity is defined by the number of suction ports, i.e., the number of discharge ports. With a rated output power of 20W, if the rated discharge capacity per port is 1mAh, then each power range corresponds to 30 discharge ports. That is, when the capacity of the power module 11 is within this power range, the supported total suction time is 60s. Figure 7 As shown, the number of discharge ports in each of the power ranges are smoothly connected to form the discharge curve of the power module 11.

[0132] During the discharge process of the atomizing device 1, the processing module 13 uses a timer to count the discharge capacity of each suction discharge every 10ms. After each suction discharge, the discharge capacity of that suction discharge is added to the total discharge capacity.

[0133] It should be noted that the preset voltage lookup table is obtained by testing the power module 11 after multiple discharges and long periods of rest at the factory. The power module 11 is discharged multiple times at a certain capacity and then left to rest for extended periods. The standard voltage corresponding to the remaining capacity of the power module 11 is then sequentially measured to form the remaining capacity-standard voltage combination, thereby enabling SOC-OCV lookup estimation of the power module 11. For example, under a standard 25°C environment, the newly manufactured power module 11 is discharged from full charge at a constant current to the cutoff voltage. Each 1% of the capacity is discharged and left to rest for 2 hours, with stable voltages collected, forming a one-to-one correspondence between remaining capacity and standard voltage from SOC=100% to SOC=0%. However, the voltage recovery of the power module 11 after the actual discharge process is affected by a variety of factors. Therefore, it is easy to make a deviation in obtaining the remaining capacity of the power module 11 by simply estimating the SOC-OCV table based on the voltage of the power module 11 after the voltage recovery. This can mislead the subsequent discharge strategy, resulting in a decline in user experience, damage to the power module 11, and other problems.

[0134] In this embodiment, the remaining capacity can be calculated based on the total capacity of the power module 11 and the accumulated discharge capacity, that is, the total capacity of the power module 11 minus the discharge capacity. The corresponding standard voltage can be obtained by consulting the preset voltage lookup table.

[0135] The voltage of the power module 11 is obtained and compared with the standard voltage. If there is a deviation, it means that the voltage of the power module 11 has deviated from the standard voltage obtained based on the actual capacity of the power module 11. That is, the remaining capacity or voltage of the power module 11 is determined to have a large error by looking up the preset voltage reference table. At this time, it is necessary to correct the number of discharge ports in each power range, that is, to correct the discharge curve of the power module 11.

[0136] It is understood that in this embodiment, the discharge port quota of the current power range is adjusted according to the direction and magnitude of the deviation, so that the port allocation matches the actual remaining capacity of the power module 11, thereby achieving the purpose of ensuring the uniformity of the port number and the stability of the battery life across the entire power range.

[0137] In one possible implementation, please refer to [the relevant documentation / reference]. Figure 8 , Figure 8 This is a schematic diagram illustrating the process of correcting the number of discharge ports according to another embodiment of this application. The step of correcting the number of discharge ports based on the voltage of the power module 11 and the standard voltage specifically includes:

[0138] S801, when the voltage of the power module is greater than the standard voltage, reduce the number of discharge ports in the current power range and allocate the quota of the excess discharge ports to the subsequent power range.

[0139] S802, when the voltage of the power module is less than the standard voltage, the number of discharge ports in the current power range is increased, and the quota of the increased number of discharge ports comes from the subsequent power range.

[0140] Specifically, in this embodiment, when the actual voltage of the power module 11 is greater than the standard voltage, it indicates that the actual remaining capacity of the power module 11 is greater than the expected estimate, and the load-carrying capacity of the current power range is higher than expected. If the discharge continues according to the original quota of discharge ports, the power consumption in the high-voltage range will be too fast, and the capacity in the low-power range will be insufficient in the later stages. At this time, the remaining discharge port quota of the current power range is reduced, and the reduced quota is evenly distributed to the subsequent low-power ranges. For example, if the discharge port number of the current power range is 30 ports (60s, 20W), and the measured voltage of the power module 11 is higher than the standard voltage, then the remaining quota of the power range is reduced to 25 ports (50s, 20W), and the reduced quota of 5 ports can be evenly distributed to the subsequent multiple power ranges.

[0141] Conversely, when the measured voltage of the power module 11 is lower than the standard voltage, it indicates that the actual remaining capacity of the power module 11 is less than the expected estimate, and the load-carrying capacity of the current power range is lower than expected. If the discharge continues according to the original quota, it will lead to premature capacity depletion and trigger undervoltage lockout. In this case, the discharge port quota for the current power range is increased by shifting the corresponding quota from subsequent power ranges to the current power range. For example, if the discharge port number for the current power range is 30 ports, and the measured voltage of the power module 11 is lower than the standard voltage, then the discharge port number for the current power range is increased to 33 ports. The increased quota of 3 ports is shifted by shifting 1 port from each subsequent power range to the current power range. It can be understood that in this embodiment, through this quota shifting method of the discharge port number, the total number of discharge ports always remains consistent with the factory calibration value, and there will be no problem of falsely advertised battery life. At the same time, a uniform distribution of the number of ports across the entire power range is achieved.

[0142] It should be noted that the specific quota values, shifts, and allocation methods for the number of discharge ports mentioned above are all illustrative examples provided by this application to better understand this embodiment, and this application does not impose any limitations on them.

[0143] In one possible implementation, please refer to [the relevant documentation / reference]. Figure 9 , Figure 9 A schematic diagram illustrating the capacity correction process for a power module 11 provided in another embodiment of this application. The method further includes:

[0144] S901, when the voltage of the power module is less than the warning voltage threshold, calculate the corrected capacity based on the remaining capacity corresponding to the voltage of the power module and the remaining capacity corresponding to the standard voltage.

[0145] S902, adjust the number of discharge ports according to the adjusted capacity and the remaining capacity corresponding to the voltage of the power module.

[0146] Specifically, in this embodiment, when the measured voltage of the power module 11 is lower than the warning voltage threshold, it indicates that the power module 11 has entered the end of the discharge period, the voltage drop rate is accelerating, and there is a risk of suddenly dropping below the cutoff voltage of the power module 11, resulting in a sudden interruption of the pumping discharge. At this time, the warning capacity correction mechanism should be triggered.

[0147] For example, if the warning voltage threshold is set to 3.65V, during the discharge process of the power module 11, when the voltage of the power module 11 is 3.65V, the actual remaining capacity of the power module 11 is approximately 15%, while the power range at this time is between 20% and 10%. The corresponding discharge strategy is still 30 discharge ports (60s, 20W). However, the actual remaining capacity of the power module 11 no longer supports this number of discharge ports. Therefore, it is necessary to adjust the number of discharge ports according to the corrected capacity and the remaining capacity corresponding to the voltage of the power module 11. Specifically, the relationship between the corrected capacity and the corrected number of discharge ports is as follows:

[0148] ,

[0149] in, To correct the capacity, The interval for dividing two adjacent electrical ranges. This is the corrected number of discharge ports. This represents the number of discharge ports before correction. In this embodiment, 10%, It is 30. Substituting these values ​​into the above formula, we can obtain the corrected number of discharge ports. The number of ports is 15, meaning the number of ports for discharge in this power range is corrected to 15 (30s, 20W).

[0150] It is understood that in this embodiment, by setting the warning voltage threshold of the power module 11, the safety capacity of the power module 11 is reserved in advance to avoid the voltage of the power module 11 from dropping rapidly to the cutoff voltage and causing sudden disconnection, while preventing the power module 11 from being over-discharged and damaged, thus extending the service life of the power module 11.

[0151] It should be noted that in other possible implementations, the relationship between the warning voltage threshold and the corrected capacity and the corrected number of discharge ports can be other values ​​or relationships, and this application does not limit them.

[0152] In one possible implementation, the method further includes:

[0153] The target parameters are adjusted based on the discharge capacity, the total capacity of the power module 11, and the preset voltage lookup table, according to a complete charge-discharge cycle.

[0154] Specifically, in this embodiment, a complete charge-discharge cycle is defined as follows: the power module 11 starts discharging from a fully charged state (4.2V) until the voltage of the power module 11 drops to the cutoff voltage (3.2V), thus completing a complete discharge cycle; then it is charged to 4.2V by the charging module 15 to complete a complete charging cycle.

[0155] Understandably, in this embodiment, after each complete charge-discharge cycle, all initial parameters, voltage response parameters, actual discharge capacity, and actual charge capacity of that cycle are recorded. This allows the measured data to be fused with historical data, updating the mapping relationship between initial parameters and voltage response parameters, as well as the influence weight matrix of each parameter. Through this full-cycle self-learning recording mechanism, the atomizing device 1 can automatically adapt to changes in characteristics such as increased internal resistance, capacity decay, and OCV curve shift caused by the cyclic aging of the power module 11. It continuously optimizes target parameters and discharge strategies, ensuring the consistency of voltage compensation accuracy, SOC estimation accuracy, and vaping experience throughout the product's entire lifecycle.

[0156] In one possible implementation, please refer to [the relevant documentation / reference]. Figure 10 and Figure 11 , Figure 10 A schematic diagram of the frame of the atomizing device 1 provided for yet another embodiment of this application; Figure 11This is a schematic diagram illustrating the process of obtaining the total capacity of the power module 11 according to another embodiment of this application. The atomizing device 1 further includes a charging module 15. The step of obtaining the total capacity of the power module 11 and dividing it into multiple power ranges based on the total capacity of the power module 11 specifically includes:

[0157] S1101, Obtain the charging parameters of the charging module;

[0158] S1102, Obtain the cumulative charging capacity of the power module according to the charging parameters;

[0159] S1103, Based on the charging capacity, obtain the total capacity of the power module based on a complete charging cycle.

[0160] Specifically, in this embodiment, when the power module 11 is charging, the processing module 13 collects the charging current of the charging module 15 in real time and accumulates the charging time of charging the power module 11 once. The capacity of this charging cycle can be calculated by the charging time and charging current. After a complete charge and discharge cycle, the total accumulated charging capacity is the actual total capacity of the power module 11.

[0161] In this embodiment, based on the obtained true total capacity, the battery can be redivided into multiple capacity ranges, and the power and corresponding number of discharge ports for each capacity range can be calculated. It is understood that this embodiment can automatically accommodate capacity differences between different batches of batteries, individual differences, and capacity decay after cycle aging, eliminating the need for the production line to individually program parameters for each device, significantly reducing production costs and management complexity.
