In related technologies, users can add test points at both ends of the voltage conversion module to determine its current loss and, consequently, its power consumption.

[0003] However, in the above method, since the test points are generally implemented by resistors, and the resistors themselves have a certain impedance, the output efficiency of the voltage conversion module detected by the electronic device is reduced. As a result, the power consumption of the voltage conversion module detected by the electronic device is inaccurate. Summary of the Invention

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0024] The power consumption detection method for the voltage conversion module provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0025] With the development of electronic devices, the number of applications on these devices is increasing, and the functions of these applications are also expanding. Therefore, ensuring the battery life of electronic devices in this context is a pressing technical problem. Typically, electronic devices can be charged quickly by connecting fast charging cells in parallel, thus solving the battery life issue. However, because the fast charging cells are connected in parallel, the output voltage of the fast charging cells in the electronic device will double. To address the issue of this voltage doubling, electronic device manufacturers can use voltage conversion modules to convert the doubled voltage output by the fast charging cells into a normal voltage usable by the electronic device.

[0026] For example, such as Figure 1 As shown, the charging module 10 in the electronic device may include a charging module 11, a voltage conversion module 12, and a fast charging core 13; wherein, the charging module 11 can be connected to the voltage conversion module 12, the voltage conversion module 12 is bidirectionally connected to the fast charging core 13, and the voltage conversion module 12 is connected to other modules 14 in the electronic device; wherein, the fast charging core 13 is a pure battery cell, the charging module 11 is used to charge the fast charging core 13, in the discharging scenario, the fast charging core 13 supplies power to the electronic device, and in the charging scenario, the charging module 11 supplies power to both the fast charging core 13 and the electronic device.

[0027] Because electronic devices incorporate voltage conversion modules, they experience additional overall power consumption losses. Typically, users add test points at both ends of the voltage conversion module and then use ammeters to collect two sets of current data. After obtaining these two sets of current data, the electronic device can calculate the power consumption loss of the voltage conversion module by measuring the current loss at both ends.

[0028] For example, such as Figure 2 As shown, in conventional technology, users can add test points 15 at the front end and test points 16 at the back end of the voltage conversion module 12, so that electronic devices can determine the power consumption loss of the voltage conversion module based on the current passing through these two test points.

[0029] However, the addition of test points at both the front and rear ends of the voltage conversion module, typically implemented using resistors, can affect the stability of the original circuit and reduce voltage conversion efficiency. Secondly, the above solution cannot measure the efficiency of the voltage conversion module in real time. This is because real-time measurement would require adding an extra ammeter within the electronic device, increasing hardware costs. Even if a single ammeter is inexpensive, the cost becomes significant when applied to mass-produced electronic devices.

[0030] In this embodiment, the input power of the voltage conversion module at the target time point is determined based on the output voltage and output current of the fast charging cell at the target time point. Based on the input power and the relationship between the input power of the voltage conversion module and the voltage conversion efficiency of the voltage conversion module, the voltage conversion efficiency of the voltage conversion module at the target time point is determined. Based on the voltage conversion efficiency, the power consumption loss value of the voltage conversion module at the target time point is determined. This avoids the influence of the resistance at the test point on the power consumption detection result of the voltage conversion module, and improves the accuracy of power consumption detection of the voltage conversion module.

[0031] The power consumption detection method provided in this application can be implemented by a power consumption detection device, which can be an electronic device or a functional module within an electronic device. The electronic device includes a fast-charging core and a voltage conversion module connected to the fast-charging core. The following description uses an electronic device as an example to illustrate the technical solution provided in this application.

[0032] This application provides a power consumption detection method. Figure 3 A flowchart of a power consumption detection method provided in an embodiment of this application is shown. Figure 3 As shown, the power consumption detection method provided in this application embodiment may include the following steps 201 to 203.

[0033] Step 201: The electronic device determines the input power of the voltage conversion module at the target time point based on the output voltage and current of the fast charging chip. It can be understood that since the fast charging chip is directly connected to the voltage conversion module, the electronic device can obtain the output power of the fast charging chip based on its output voltage and current, and thus obtain the input power of the voltage conversion module.

[0034] In this embodiment, the target time point can be the current time point in the electronic device's system. This embodiment uses the target time point as an example to illustrate the calculation process of the power loss value of the voltage conversion module at each sampling time point.

[0035] In this embodiment of the application, the fast charging core can be a battery module in an electronic device.

[0036] In some embodiments of this application, the battery module can be a dual-cell or multi-cell module, wherein the number of multi-cell modules is greater than the number of dual-cell modules.

[0037] It is understood that, in related technologies, those skilled in the art can add a power testing module to the fast charging cell. This power testing module can measure the output power of the fast charging cell in real time. Therefore, this application can directly use the power testing module to obtain the output power of the voltage conversion module in real time, without the need to add additional hardware circuitry, thus saving hardware costs.

[0038] In this embodiment of the application, the electronic device marks the sampling period according to the sampling duration to evenly divide it into multiple sampling time periods, and determines each sampling time point, i.e. the aforementioned target time point, within each sampling time period.

[0039] In some embodiments of this application, the target time point can be any point corresponding to any location within a preset sampling period.

[0040] For example, the electronic device marks the sampling period according to the sampling duration to evenly divide it into multiple sampling time periods, and determines the target time point within each sampling time period.

[0041] Preferably, the target time point can be the point corresponding to the end of a sampling time period.

[0042] For example, assuming the current time is 18:00, the electronic device can take a 2-minute sampling period. Then, at 18:02, the electronic device can determine the input power of the voltage conversion module at 18:02 based on the output power of the fast charging cell obtained by the power testing module at 18:02.

[0043] It is understandable that electronic devices can uniformly sample the output voltage and output current of the fast charging cell in the electronic device according to the sampling time period, thereby obtaining the input power of the voltage conversion module at the target time point.

[0044] Optionally, in the embodiments of this application, combined with Figure 3 ,like Figure 4 As shown, step 201 can be implemented through steps 201a and 201b below.

[0045] Step 201a: When the electronic device is in discharge mode, the electronic device acquires the output voltage and output current of the fast charging cell at the target time point.

[0046] In this embodiment, since the voltage conversion module and the fast charging cell are connected, the input power of the voltage conversion module can be equivalently obtained by acquiring the output voltage and output current of the fast charging cell.

[0047] In some embodiments of this application, the output voltage and output current of the fast charging chip at the target time point can be obtained by a power testing module.

[0048] Step 201b: The electronic device determines the input power of the voltage conversion module at the target time point based on the output voltage and output current.

[0049] In this embodiment, after obtaining the output voltage and output current of the fast charging cell at the target time point, the electronic device can multiply the output voltage and output current of the fast charging cell to obtain the input power of the voltage conversion module at the target time point.

[0050] For example, the input power of the voltage conversion module at the target time point can be determined by the following formula 1 based on the output voltage and output current of the fast charging cell at the target time point:

[0051] P(battery) = V(battery) * I(battery) (Formula 1)

[0052] Where P(battery) is the input power of the voltage conversion module at the target time point, V(battery) is the output voltage of the fast charging cell at the target time point, and I(battery) is the output current of the fast charging cell at the target time point.

[0053] In this embodiment, the electronic device can obtain the input power of the voltage conversion module at the target time point by the output power of the fast charging cell at the target time point, without the need to add hardware structures on both sides of the voltage conversion module, thus reducing hardware costs.

[0054] Optionally, in the embodiments of this application, combined with Figure 3 ,like Figure 5 As shown, step 201 can be implemented through steps 201c and 201d as described below.

[0055] Step 201c: When the electronic device is in charging mode, the electronic device obtains the input power of the fast charging core at the target time point, and the output power of the charging module connected to the voltage conversion module at the target time point.

[0056] In this embodiment, the output power of the charging module can be determined by the output current and output voltage of the charging module, and the input power of the fast charging core can be determined by the input current and input voltage of the fast charging core.

[0057] For example, the output power of the above-mentioned charging module can be determined by the following formula 2, the specific formula being:

[0058] P(charger)= v(charge) * I(charge) (Formula 2)

[0059] Where P(charger) is the output power of the charging module, v(charge) is the output voltage of the charging module, and I(charge) is the output current of the charging module.

[0060] For example, the input power of the aforementioned fast charging cell can be determined by the following formula 3, specifically:

[0061] P(battery)= v(battery) * I(battery) (Formula 3)

[0062] Where P(battery) is the input power of the fast charging cell at the target time point, v(battery) is the input voltage of the fast charging cell at the target time point, and I(battery) is the input current of the fast charging cell at the target time point.

[0063] Step 201d: The electronic device determines the input power of the voltage conversion module at the target time point based on the difference between the output power of the charging module and the input power of the fast charging cell.

[0064] Specifically, after obtaining the output power of the charging module and the input power of the fast charging core, the electronic device can obtain the input power of the voltage conversion module according to the following formula 4:

[0065] P(input) = P(charger) – P(battery) (Formula 4)

[0066] Wherein, P(input) is the input power of the voltage conversion module, P(charger) is the output power of the charging module, and P(battery) is the input power of the fast charging cell.

[0067] In this embodiment, the electronic device can determine the input power of the voltage conversion module in different ways under different scenarios, thereby improving the flexibility of the electronic device in obtaining the input power of the voltage conversion module.

[0068] Step 202: The electronic device determines the voltage conversion efficiency of the voltage conversion module at the target time point based on the input power and the relationship between the input power of the voltage conversion module and the voltage conversion efficiency of the voltage conversion module.

[0069] In some embodiments of this application, the voltage conversion efficiency corresponding to the input power can be preset.

[0070] Specifically, before acquiring the input power of the voltage conversion module, the electronic device can acquire a first profile, which includes at least one input power and the voltage conversion efficiency corresponding to the at least one input power. After acquiring the input power, the electronic device can find the voltage conversion efficiency corresponding to the input power.

[0071] For example, the voltage conversion efficiency described above can be represented by discrete values, and the specific degree of dispersion can be determined by the relevant personnel.

[0072] Step 203: The electronic device determines the power consumption loss value of the voltage conversion module at the target time point based on the voltage conversion efficiency.

[0073] In this embodiment of the application, after obtaining the input power and the voltage conversion efficiency corresponding to the input power, the electronic device can multiply the input power and the voltage conversion efficiency corresponding to the input power to obtain the power consumption loss value of the voltage conversion module at the target time point.

[0074] For example, the power loss value corresponding to the target time point can be obtained through the following formulas 5 and 6:

[0075] P(module) = P(battery) * e(P(battery)) (Formula 5)

[0076] E(period) = P(module) * T(period) (Formula 6)

[0077] Where P(module) is the power consumption loss of the voltage conversion module, P(battery) is the input power of the voltage conversion module, e(P(battery)) is the voltage conversion efficiency corresponding to the input power, T(period) is the duration of the sampling period, and E(period) is the power consumption loss of the voltage conversion module at the target time point.

[0078] This application provides a power consumption detection method. An electronic device can determine the input power of a voltage conversion module at a target time point based on the output voltage and current of a fast charging cell at that time point. Based on the input power and the relationship between the input power and the voltage conversion efficiency of the voltage conversion module, the voltage conversion efficiency of the voltage conversion module at the target time point is determined. The power consumption loss value of the voltage conversion module at the target time point is then determined based on the voltage conversion efficiency. This method avoids the influence of the resistance at the test point on the power consumption detection results of the voltage conversion module, thus improving the accuracy of power consumption detection for the voltage conversion module.

[0079] Optionally, in the embodiments of this application, combined with Figure 3 ,like Figure 6 As shown, before step 202 above, the power consumption detection method provided in this application embodiment further includes steps 301 and 302 below, and step 202 above can be specifically implemented by step 202a below.

[0080] Step 301: The electronic device acquires the operating mode of the voltage conversion module at the target time point.

[0081] In this embodiment, the electronic device can determine the operating mode at the target time point based on the operating status of the voltage conversion module at the target time point.

[0082] In some embodiments of this application, the operating mode of the voltage conversion module can be associated with the output power of the voltage conversion module.

[0083] For example, assuming the current output power of the voltage conversion module is low, the electronic device can determine that the voltage conversion module is currently in an energy-saving operating mode.

[0084] It is understandable that the above implementation scheme takes into account the operating modes of the voltage conversion module. In fact, to improve operating efficiency under different input currents while ensuring operational stability, voltage conversion modules typically operate in different modes. For example, in high-current scenarios (a common engineering configuration is above 200mA), the ripple effect of the system circuit is relatively small, and to improve efficiency, the system often adopts a dynamic frequency modulation mode; in low-current scenarios, the ripple effect of the system circuit is relatively large, and to improve stability, the system often adopts a fixed frequency strategy, in which case the operating efficiency is lower.

[0085] Step 302: The electronic device obtains the relationship between the input power and voltage conversion efficiency of the voltage conversion module in the working mode.

[0086] In some embodiments of this application, the voltage conversion efficiency of the voltage conversion module varies under different operating modes at the same input power.

[0087] In some embodiments of this application, the electronic device can obtain the relationship between the input power and voltage conversion efficiency of the voltage conversion module in the operating mode according to the second configuration file.

[0088] Step 202a: The electronic device determines the voltage conversion efficiency of the voltage conversion module at the target time point based on the input efficiency and the relationship between the input power and voltage conversion efficiency of the voltage conversion module in the working mode.

[0089] In some embodiments of this application, the electronic device can obtain the voltage conversion efficiency that matches the operating mode under the current input power according to the second configuration file.

[0090] Specifically, before acquiring the input power of the voltage conversion module, the electronic device can acquire at least one second profile, each profile corresponding to a working mode. Each second profile includes at least one input power and the voltage conversion efficiency corresponding to at least one input power in that mode. After the electronic device acquires the input power, it can find the voltage conversion efficiency corresponding to that working mode based on the input power.

[0091] In this embodiment, the electronic device can obtain different voltage conversion efficiencies according to different operating modes of the voltage conversion module, thereby obtaining different power loss values, which improves the flexibility of the electronic device in obtaining power loss values.

[0092] Optionally, in the embodiments of this application, each sampling period includes at least two sampling time periods, and each sampling time period includes at least two time points; the power consumption detection method provided in the embodiments of this application further includes the following steps 401 and 402.

[0093] Step 401: The electronic device uses the power loss value of the voltage conversion module at the target time point as the power loss value of the voltage conversion module during the target sampling time period.

[0094] It is understandable that electronic devices can use the power loss value of the voltage conversion module at the target time point to reflect the power loss value of the voltage conversion module during the sampling time period to which the target time point belongs.

[0095] In some embodiments of this application, for each sampling time period, the electronic device may perform one or more uniform samplings in each sampling time period to obtain N power loss values, where N is a positive integer.

[0096] It should be noted that if uniform sampling is performed once within each sampling time period, then one power loss value directly corresponds to one sampling time period; if uniform sampling is performed multiple times within each sampling time period, then the average of the multiple power loss values ​​is taken as the power loss value corresponding to that sampling time period.

[0097] In some embodiments of this application, the durations of the above-mentioned at least two sampling time periods may be equal or unequal.

[0098] In some embodiments of this application, the duration of the above-mentioned at least two sampling time periods can be preset by the user; or determined by the electronic device according to the sampling period.

[0099] Step 402: The electronic device determines the power consumption loss value of the voltage conversion module within the sampling period based on the power consumption loss value of the voltage conversion module within each sampling time period.

[0100] In this embodiment of the application, after obtaining the power loss value of the voltage conversion module in each sampling time period, the electronic device can sum the power loss values ​​corresponding to each sampling time period to obtain the power loss value of the voltage conversion module in the sampling period.

[0101] In this embodiment, the electronic device can obtain the power loss value of the voltage conversion module in real time during the sampling period by using the power loss value in each sampling time period, so that the power consumption of the voltage conversion module at the current moment obtained by the electronic device is more accurate.

[0102] Optionally, in this embodiment of the application, step 402 can be implemented by step 402a as described below.

[0103] Step 402a: The electronic device calculates the sum of the power loss values ​​of the voltage conversion module in each sampling time period to obtain the power loss value of the voltage conversion module in the sampling period.

[0104] For example, the electronic device can obtain the power consumption loss value of the voltage conversion module during the sampling period using the following formula 7:

[0105] E(sum) = SUM[P(module) * T(period)] (Formula 7)

[0106] Where E(sum) is the power consumption loss of the voltage conversion module during the sampling period, P(module) is the power loss value, and T(period) is the duration corresponding to the sampling time period.

[0107] It should be noted that Formula 7 above is the power loss value of the voltage conversion module obtained by the electronic device during the sampling period when the sampling time period is the same. If the sampling time periods are different, the electronic device can obtain the power loss value of the voltage conversion module at different target time points according to Formula 6 above, and then superimpose the power loss values ​​of the voltage conversion module at different target time points to obtain the power loss value of the voltage conversion module during the sampling period.

[0108] In this embodiment, the electronic device can sum the power loss values ​​within each sampling time period to obtain the power loss value of the voltage conversion module within the sampling period. In this way, the power consumption of the voltage conversion module at the current moment obtained by the electronic device is more accurate.

[0109] For example, the power consumption detection method provided in this application for an electronic device in a discharged state will be explained and illustrated below through specific examples.

[0110] Step 21: When the electronic device is in a discharging state and the system time of the electronic device matches the target time point, the electronic device can obtain the output power of the charging cell in real time and use the output power of the charging cell as the input power of the voltage conversion module.

[0111] In this embodiment of the application, the specific process can be implemented using the above formula 1.

[0112] Step 22: The electronic device obtains the efficiency of the voltage conversion module under different input powers in the discharge state.

[0113] In this embodiment, the electronic device can add the efficiency of the voltage conversion module under different input powers and different input powers to the configuration file, with one input power corresponding to one efficiency.

[0114] Step 23: The electronic device multiplies the input power of the voltage conversion module with the efficiency corresponding to that input power to obtain the efficiency loss value of the voltage conversion module at the target time point.

[0115] In some embodiments of this application, the aforementioned target time point is one or more.

[0116] Step 24: Superimpose the efficiency loss values ​​at each target time point, and multiply the superimposed efficiency loss value by the duration of the sampling period to obtain the efficiency loss value of the voltage conversion module within the sampling period.

[0117] Optionally, in the embodiments of this application, step 22 above can be replaced by the electronic device obtaining the efficiency of the voltage conversion module under different modes and the corresponding different input powers in the discharge state.

[0118] In this embodiment, the electronic device can obtain the input power of the voltage conversion module through the output power of the charging cell, without the need to add hardware structures on both sides of the voltage conversion module, thus reducing hardware costs.

[0119] Furthermore, by way of example, the power consumption detection method provided in this application for an electronic device in a charging state will be explained and illustrated below through specific examples.

[0120] Step 31: When the electronic device is in a charging state and the system time of the electronic device matches the target time point, the electronic device can obtain the input power of the charging cell and the output power of the charging module in real time, and use the difference between the input power of the charging cell and the output power of the charging module as the input power of the voltage conversion module.

[0121] Step 32: The electronic device obtains the efficiency of the voltage conversion module under different input powers during the charging state.

[0122] In this embodiment, the electronic device can add the efficiency of the voltage conversion module under different input powers and different input powers to the configuration file, with one input power corresponding to one efficiency.

[0123] Step 33: The electronic device multiplies the input power of the voltage conversion module with the efficiency corresponding to that input power to obtain the efficiency loss value of the voltage conversion module at the target time point.

[0124] In this embodiment of the application, the aforementioned target time point can be one or more.

[0125] Step 34: The electronic device superimposes the efficiency loss values ​​at each target time point and multiplies the superimposed efficiency loss value by the duration of the sampling time period to obtain the efficiency loss value of the voltage conversion module within the sampling period.

[0126] Optionally, in the embodiments of this application, step 32 above can be replaced by the electronic device obtaining the efficiency of the voltage conversion module under different modes and the corresponding different input powers in the charging state.

[0127] In this embodiment, the electronic device can determine the input power of the voltage conversion module in different ways under different scenarios, thereby improving the flexibility of the electronic device in obtaining the input power of the voltage conversion module.

[0128] It should be noted that the power consumption detection method provided in this application can be executed by a power consumption detection device, an electronic device, or a functional module or entity within an electronic device. This application uses a power consumption detection device executing the power consumption detection method as an example to illustrate the power consumption detection device provided in this application.

[0129] Figure 7 A schematic diagram of a possible structure of the power consumption detection device involved in an embodiment of this application is shown. For example... Figure 7 As shown, the power consumption detection device 70 may include a determination module 71 and a processing module 72.

[0130] The determining module 71 is used to determine the input power of the voltage conversion module at the target time point based on the output voltage and output current of the fast charging cell at the target time point; and to determine the voltage conversion efficiency of the voltage conversion module at the target time point based on the input power and the relationship between the input power and the voltage conversion efficiency of the voltage conversion module. The processing module 72 is used to determine the power consumption loss value of the voltage conversion module at the target time point based on the voltage conversion efficiency.
