[0041] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0044] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
[0045] The present application provides a shutdown voltage control method, which is applied to Figure 1 The electronic device 10 shown includes a battery for providing power for its own operation. In one embodiment, the electronic device 10 may include a mobile phone, a tablet computer, a laptop computer, a PDA, a mobile Internet device (Mobile Internet Device, MID), a wearable device (such as a smart watch, a smart bracelet, a pedometer, etc.) or other electronic devices including a battery.
[0046] like Figure 2 As shown, the embodiment of the present application provides a shutdown voltage control method, including steps 202 to 208:
[0047] Step 202, obtaining status information of the electronic device, and determining the current scene of the electronic device according to the status information; the current scene of the electronic device includes an indoor scene and an outdoor scene.
[0048] Among them, the status information of the electronic device includes information used to characterize the current working state and / or motion state of the electronic device. By analyzing the status information of the electronic device, it can be determined whether the electronic device is currently in an indoor scene or an outdoor scene. Specifically, the indoor scene may include a home scene, an office scene, an in-car scene, etc.; the outdoor scene may include an outdoor sports scene, a commuting scene, etc. Indoor scenes are more likely to have charging conditions, and outdoor scenes are more likely not to have charging conditions. Based on this, the possibility of having charging conditions can be analyzed according to whether the current scene is an indoor scene or an outdoor scene.
[0049] Step 204, obtaining the battery temperature;
[0050] Battery temperature refers to the temperature of the battery inside the electronic device. Battery temperature is affected by ambient temperature. At the same time, the temperature of the battery will also change during charging or discharging. At low temperatures, the activity of the electrolyte in the battery deteriorates, the impedance of the battery cell rises sharply, and the effective discharge capacity also decreases rapidly. If the battery discharge cut-off voltage is low at low temperatures, the battery life will be shortened; and shallow charging and discharging of the battery can effectively extend the battery life. The lower the battery discharge cut-off voltage, the smaller the voltage difference between the positive and negative electrodes, and the more lithium ions and electrolytes participate in the cycle feedback. The lower the battery discharge cut-off voltage, the higher the discharge capacity. After a certain number of cycles, the capacity of the battery with a low discharge cut-off voltage will drop rapidly, mainly due to the gradual consumption of lithium ions and electrolytes during the repair process of the solid electrolyte interface film (SEI) formed on the surface of the negative electrode material, which directly leads to a decrease in capacity.
[0051] Step 206, determining shutdown voltage control information according to the scene and battery temperature;
[0052] Based on the current scenario of the electronic device and the battery temperature, the shutdown voltage regulation information is determined to balance the battery life and user usage time.
[0053] For example, if the battery temperature is low (for example, 10°C) and the current scene is indoors, it is likely that the conditions for charging are met, and the shutdown voltage can be appropriately increased to encourage the user to charge as soon as possible; if the battery temperature is high (for example, 30°C) and the current scene is outdoor, it is likely that the conditions for charging are not met, and the shutdown voltage can be appropriately lowered so that the user can extend the usable time of the electronic device to a certain extent.
[0054] Step 208: adjusting the shutdown voltage of the electronic device according to the shutdown voltage regulation information.
[0055] When the battery voltage of the electronic device reaches the shutdown voltage, the electronic device will automatically shut down to stop the battery from discharging. The shutdown voltage is adjusted according to the determined shutdown voltage control information to change the battery discharge cut-off voltage. The battery power of the electronic device can be reflected by the battery voltage. The remaining battery power can be judged according to the size of the battery voltage. The battery voltage is positively correlated with the battery power. When the battery power is high, the battery voltage is also high. Therefore, when the battery voltage reaches the shutdown voltage, that is, the battery power is lower than a certain power, the electronic device will automatically shut down.
[0056] The above-mentioned shutdown voltage control method obtains status information of the electronic device, determines the current scene of the electronic device according to the status information, obtains the battery temperature, and determines the shutdown voltage regulation information according to the scene and the battery temperature to adjust the shutdown voltage of the electronic device. It comprehensively considers the impact of temperature on battery life and the user experience brought by the battery life of the electronic device in different usage scenarios, so as to realize dynamic regulation of the shutdown voltage, delay battery aging and ensure user experience at the same time.
[0057] like Figure 3 As shown, in one embodiment, based on the scene being an outdoor scene, the step of determining shutdown voltage regulation information according to the scene and battery temperature includes steps 302 to 306:
[0058] Step 302: Compare the battery temperature with a preset temperature threshold.
[0059] The temperature threshold includes a first temperature threshold and a second temperature threshold, wherein the first temperature threshold is less than the second temperature threshold. When the battery temperature is below the first temperature threshold, the battery cycle life is greatly affected by deep discharge; when the battery temperature is between the first temperature threshold and the second temperature threshold, the battery cycle life is less affected by deep discharge, but there is a certain impact; when the battery temperature is greater than the second temperature threshold, the battery discharge cut-off voltage decreases appropriately, which has little impact on the battery cycle life. It can be understood that under different temperature thresholds, the battery cycle life is affected differently by deep discharge, and the first temperature threshold, the second temperature threshold and the third temperature threshold are used to divide the degree to which the battery cycle life is affected by deep discharge into multiple intervals.
[0060] Step 304 : if the battery temperature is greater than the first temperature threshold and less than the second temperature threshold, the shutdown voltage is maintained at a preset reference shutdown voltage.
[0061] The reference shutdown voltage is a discharge cut-off voltage of the battery that can ensure the cycle life of the battery under normal temperature (eg, 25° C.).
[0062] When the electronic device is located outdoors, it is very likely that charging conditions are not available. At this temperature, the battery cycle life is less affected by deep discharge, so the shutdown voltage is maintained at a preset reference shutdown voltage.
[0063] Step 306 : if the battery temperature is greater than the second temperature threshold, determine to lower the shutdown voltage based on the reference shutdown voltage to adjust it to the first voltage.
[0064] When the electronic device is located outdoors, it is very likely that charging conditions are not available. At this time, if the temperature is high, deep discharge has little effect on the battery cycle life. Since the user may not be able to charge in time at this time, if the electronic device automatically shuts down, it may affect the user's current activities. The shutdown voltage can be appropriately lowered based on the reference shutdown voltage. The shutdown voltage can be lowered to the first voltage to extend the usable time of the electronic device before charging.
[0065] like Figure 4 As shown, in one embodiment, based on the scene being an outdoor scene, if the battery temperature is greater than the second temperature threshold, the step of determining to lower the shutdown voltage based on the reference shutdown voltage to adjust to the first voltage includes steps 402 to 406:
[0066] Step 402, obtaining the battery voltage.
[0067] Battery voltage is a measure of the remaining charge in the battery.
[0068] Step 404: compare the battery voltage with a preset warning voltage.
[0069] The warning voltage is used as a trigger condition for triggering a low-battery reminder. When the battery voltage is higher than the warning voltage, it indicates that the battery power is lower than the warning power. At this time, the electronic device will issue a low-battery reminder to remind the user to charge the electronic device as soon as possible.
[0070] Step 406 : if the battery voltage is lower than the preset warning voltage and the battery temperature is greater than the second temperature threshold, determine to lower the shutdown voltage based on the reference shutdown voltage to adjust it to the first voltage.
[0071] When the electronic device is in an outdoor scene, it is very likely that the charging conditions are not met. At this time, if the temperature is high, deep discharge has little effect on the battery cycle life. Since the user may not be able to charge in time at this time, if the electronic device automatically shuts down, it may affect the user's current activities. When the electronic device triggers a low-battery prompt, the shutdown voltage can be appropriately lowered based on the reference shutdown voltage, and the shutdown voltage can be lowered to the first voltage to extend the usable time of the electronic device before charging, providing the user with a certain amount of time to handle emergencies.
[0072] like Figure 5 As shown, in one embodiment, based on the scene being an indoor scene, the step of determining shutdown voltage regulation information according to the scene and battery temperature includes steps 502 to 506:
[0073] Step 502: Compare the battery temperature with a preset temperature threshold.
[0074] The temperature threshold includes a first temperature threshold, a second temperature threshold, and a third temperature threshold, wherein the first temperature threshold is less than the third temperature threshold, and the third temperature threshold is less than the second temperature threshold. When the battery temperature is below the first temperature threshold, the battery cycle life is greatly affected by deep discharge; when the battery temperature is between the first temperature threshold and the second temperature threshold, the battery cycle life is less affected by deep discharge, but there is a certain impact, wherein, when the battery temperature is between the third temperature threshold and the second temperature threshold, the battery cycle life is less affected by deep discharge; when the battery temperature is greater than the second temperature threshold, the battery discharge cut-off voltage decreases appropriately and has less impact on the battery cycle life. It can be understood that under different temperature thresholds, the battery cycle life is affected differently by deep discharge, and the first temperature threshold, the second temperature threshold, and the third temperature threshold are used to divide the degree to which the battery cycle life is affected by deep discharge into multiple intervals.
[0075] Step 504 : if the battery temperature is greater than the third temperature threshold, determine to maintain the shutdown voltage at a preset reference shutdown voltage.
[0076] The reference shutdown voltage is a discharge cut-off voltage of the battery that can ensure the cycle life of the battery under normal temperature (eg, 25° C.).
[0077] When the electronic device is located indoors, it is more likely to be in charging conditions. At this temperature, the battery cycle life is less affected by deep discharge, so the shutdown voltage is maintained at a preset reference shutdown voltage.
[0078] Step 506 : if the battery temperature is greater than the first temperature threshold and less than the third temperature threshold, determine to increase the shutdown voltage based on the reference shutdown voltage to adjust it to the second voltage.
[0079] When the electronic device is located indoors, it is more likely to be in charging conditions. At this time, if the battery temperature is greater than the first temperature threshold and less than the third temperature threshold, the shutdown voltage can be appropriately increased to encourage the user to charge as soon as possible to extend the battery cycle life.
[0080] like Figure 6 As shown, in one embodiment, the step of determining shutdown voltage regulation information according to the scenario and the battery temperature further includes steps 602 to 604:
[0081] Step 602: Compare the battery temperature with a preset temperature threshold.
[0082] The temperature threshold includes a first temperature threshold, a second temperature threshold, and a third temperature threshold, wherein the first temperature threshold is less than the third temperature threshold, and the third temperature threshold is less than the second temperature threshold. When the battery temperature is below the first temperature threshold, the battery cycle life is greatly affected by deep discharge. When the battery temperature is between the first temperature threshold and the second temperature threshold, the battery cycle life is less affected by deep discharge, but there is a certain impact, wherein when the battery temperature is between the third temperature threshold and the second temperature threshold, the battery cycle life is less affected by deep discharge; when the battery temperature is greater than the second temperature threshold, the battery discharge cut-off voltage decreases appropriately and has less impact on the battery cycle life. It can be understood that under different temperature thresholds, the battery cycle life is affected differently by deep discharge, and the first temperature threshold, the second temperature threshold, and the third temperature threshold are used to divide the degree to which the battery cycle life is affected by deep discharge into multiple intervals.
[0083] Step 604 : if the battery temperature is lower than the first temperature threshold, determine to increase the shutdown voltage based on the reference shutdown voltage to adjust it to a third voltage.
[0084] When the battery temperature is lower than the first temperature threshold, the battery cycle life is greatly affected by deep discharge. In order not to shorten the battery cycle life, the shutdown voltage can be increased based on the reference shutdown voltage regardless of whether the charging conditions are met. The shutdown voltage is adjusted to the third voltage to allow the electronic device to shut down in advance to avoid deep discharge of the battery at the current temperature. Since the internal resistance of the battery is large under this problem, the increase in the shutdown voltage has little effect on the use of the battery.
[0085] In one of the embodiments, the control amount of the shutdown voltage is determined according to the difference between a preset reference battery temperature and the battery temperature; the shutdown voltage at the reference battery temperature is the reference shutdown voltage.
[0086] In the embodiment of the present application, the shutdown voltage is regulated by determining the regulation amount based on the reference shutdown voltage. Specifically, the regulation amount can be determined according to the following expression:
[0087]
[0088] Among them, ΔV is the voltage regulation amount; V0 is the reference shutdown voltage; T0 is the reference battery temperature; T is the battery temperature; A is a preset proportional coefficient, and in one embodiment, A can be 200.
[0089] For example, if the reference shutdown voltage is 3.4V, the reference battery temperature is 25°C, the proportional coefficient is 200, the battery temperature is 8°C, the battery temperature is greater than the first temperature threshold and less than the third temperature threshold, and the electronic device is currently in an indoor scene, the shutdown voltage needs to be increased from the reference shutdown voltage to the second voltage, which can be calculated according to the control amount expression:
[0090]
[0091] Therefore, the second voltage is equal to 3.4V increased by 0.289V, that is, 3.689V.
[0092] In one of the embodiments, the status information includes at least one of positioning status information, motion status information, standby status information, running program information, and ambient light information.
[0093] Positioning status information is used to characterize the real-time positioning of the electronic device. Based on the real-time positioning, it can be determined whether it is currently in a home scene, office scene, outdoor scene, etc. Motion status information is used to characterize the motion state of the electronic device, including acceleration information, angular motion information, etc. Based on the motion status information, it can be determined whether it is currently in a mobile scene or a motion scene. Standby status information is used to characterize the screen status, including the screen-on status and the screen-off status. Running program information is used to reflect the current running program of the electronic device. Based on the current running program, the user's current activity can be determined. For example, if a taxi app is used, it can be determined that the device is currently in an outdoor scene and is not charging-friendly. Ambient light information is used to characterize the ambient light of the current environment in which the electronic device is located. Combined with other information, the current scene can be determined.
[0094] In an embodiment of the present application, different scenes can be associated with whether the charging conditions are met. After identifying the current scene, it can be determined whether the charging conditions are met based on a preset association relationship, and the shutdown voltage can be regulated in combination with the battery temperature.
[0095] It should be understood that although Figure 2-6 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. Moreover, Figure 2-6 At least part of the steps may include multiple steps or multiple stages. These steps or stages are not necessarily performed at the same time, but can be performed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed in turn or alternately with other steps or at least part of the steps or stages in other steps.
