[0024] In the current related technologies, most of the pre-trip charging solutions for terminal devices are limited to reminding users to charge before departure, such as the system issuing reminders based on the departure time set by the user or the preset threshold of the battery power. Although such solutions provide a certain degree of convenience, they do not take into account the differences in user habits and charging, and charging reminders are not flexible enough in most scenarios.

[0029] The processor 110 is the control center of the terminal device, and uses various interfaces and lines to connect various parts of the entire terminal device. By running or executing software programs and / or modules stored in the memory 120, and calling data stored in the memory 120, the processor 110 performs various functions of the terminal device and processes data, thereby monitoring the terminal device as a whole. Optionally, the processor 110 may include one or more processing units; optionally, the processor 110 may integrate an application processor, which mainly processes operating devices, user interfaces, and application programs, etc. Of course, other processors may also be included, which are not listed here one by one.

[0030] The memory 120 can be used to store software programs and modules. The processor 110 executes various functional applications and data processing of the terminal device by running the software programs and modules stored in the memory 120.

[0038] It is to be understood that the structure illustrated in the embodiments of the present application does not constitute a specific limitation on the terminal device. In other embodiments of the present application, the terminal device may include more or fewer components than shown in the figure, or combine certain components, or split certain components, or arrange the components differently. The components shown in the figure may be implemented in hardware, software, or a combination of software and hardware.

[0039] In order to make the purpose and technical solution of this application clearer and more intuitive, the charging reminder method, device, equipment, and storage medium provided in the embodiments of this application will be described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain this application and are not used to limit this application.

[0040] Please refer to Figure 2 , is a schematic diagram of the implementation flow of a charging reminder method provided by an embodiment of the present application. The method can be applied to Figure 1 The terminal equipment shown, such as Figure 2 As shown, the method may include the following steps 201 and 202:

[0041] Step 201, determine a charging reminder time period according to the current power of the terminal device and the full charging time, where the full charging time is used to indicate the time required to charge the terminal device from zero power to a preset cut-off power.

[0042] It should be understood that the preset cut-off power level is actually a power level that the user is more comfortable with, which can be 100% or 90%, etc. This application does not limit this.

[0043] In some embodiments, the full charging time required to charge a terminal device from zero power to a preset cutoff power is calculated, usually based on a preset standard charging power. For example, the standard charging power may include a first power and a second power, and the first power is less than the second power. The full charging time can be calculated by selecting an appropriate power according to the different times when the terminal device is plugged into the charger for charging.

[0044] In some embodiments, the terminal device can determine the charging reminder time period based on the current power level, full charging time, and the actual situation of the current charging device. For example, the charging time required to charge the terminal device from the current power level to the preset cutoff power level can be calculated based on the current power level of the terminal device and the actual situation of the current charging device, and then the charging reminder time period can be determined based on the charging time and the full charging time, which can improve the accuracy of the charging reminder time period.

[0045] Step 202: output charging reminder information within the charging reminder time period.

[0046] In some embodiments, after determining the charging reminder time period, the terminal device can output charging reminder information at any time within the charging reminder time period. It can also output charging reminder information at preset time intervals within the charging reminder time period when the user has not connected the charger. It can also output charging reminder information a preset number of times within the charging reminder time period. This application does not limit this.

[0047] Optionally, the terminal device outputs the charging reminder information by directly displaying the charging reminder information on the screen of the terminal device, or by displaying the charging reminder information on the screen of the terminal device in the form of a pop-up window, or by playing the charging reminder information in the form of a voice broadcast, etc. This application does not limit this.

[0048] In this embodiment, the charging reminder time period is first determined based on the current power of the terminal device and the full charge time, and the full charge time is used to indicate the time required to charge the terminal device from zero power to a preset cut-off power, and then the charging reminder information is output within the charging reminder time period. The charging reminder time period is determined based on the current power of the terminal device and the time required to charge the terminal device from zero power to a preset cut-off power, which can provide more accurate charging reminders, help prevent users from missing the best charging time or charging for too long, and improve the flexibility of charging reminders for terminal devices.

[0049] Based on the above embodiments, Figure 3 A schematic diagram of the implementation flow of a charging reminder method provided in another embodiment of the present application is shown in FIG. Figure 3 As shown, the method may include the following steps 301 to 303:

[0050] Step 301, obtaining the itinerary information of the terminal device, wherein the itinerary information includes the departure time.

[0051] In some embodiments, the terminal device can determine the travel information by reading information of a preset application in the terminal device, and the preset application includes at least one of a travel application, a reminder application, and a text message application.

[0052] Exemplarily, the ticket information of travel applications can be accessed through the user's authorized terminal device, and then the ticket information can be filtered according to the current date and time to determine the itinerary information. It is also possible to access the itinerary created by the user in reminder applications such as calendars / reminders, and directly read the itinerary information. For example, the itinerary list in the reminder includes two itinerary information, "going to Guangzhou for a meeting on April 2" and "going to Hangzhou for a trip on October 1". It is also possible to access the SMS application in the user's terminal device, determine the reservation information based on the sender of the SMS information and / or the keywords included in the SMS information, and determine the reservation information as the itinerary information. Exemplarily, if the sender of the SMS information is the server of the station, the server of the hotel, or the server of the scenic spot, the SMS information is determined as the reservation information. Or the SMS message is a notification message of a successful reservation. In this case, the SMS message usually includes keywords of the consumption items booked by the user. For example, when the consumption item is an accommodation item, the SMS message may include keywords such as "hotel", "standard room", "double room"; when the consumption item is a transportation item, the SMS message may include keywords such as "train ticket", "bus ticket", "air ticket"; when the consumption item is an entertainment item, the SMS message may include keywords such as "talk show", "movie"; when the consumption item is a food item, the SMS message may include keywords such as "hot pot".

[0053] In some embodiments, the itinerary information of the terminal device may include the time and place where the user is going to travel, as well as suggestions on what time the user should leave home and what time the user should arrive at a certain location based on the user's usual travel methods, etc. For example, the user's itinerary information is a flight at 6 pm today. After the user authorizes access to relevant information, the user's usual travel methods, such as taking a taxi, are obtained through the terminal device. Then, the time required for the user to travel from the current location to the corresponding airport by taking a taxi is calculated, for example, 1 hour. Usually, according to regulations, it is necessary to arrive at the airport two hours in advance to take a plane. Then, the terminal device can suggest that the user leave home at 3 pm and then take a taxi to the airport.

[0054] In some embodiments, the departure time included in the trip information in the embodiments of the present application is the time when the user goes out. After the user goes out, he cannot directly connect to the charger for charging. Therefore, it is necessary to remind the user to charge before the departure time so that the user has sufficient power when he goes out.

[0055] Step 302, determining a target charging time according to the current power level of the terminal device and a preset cut-off power level, where the target charging time is used to indicate the time required to charge the terminal device from the current power level to the preset cut-off power level.

[0056] In some embodiments, the preset cut-off power level is actually a power level that the user is more comfortable with, which can be 100% or 90%, etc. This application does not limit this.

[0057] In some embodiments, the terminal device may first obtain the characteristics of the energy-replenishing device that can be used in the current environment, such as learning the characteristics of the energy-replenishing device commonly used by the user in the last 1 to 3 days, and recording the maximum charging current that can be provided as I max Usually, the terminal device is charged with the maximum charging current, which can be called fast charging. The terminal device can also be charged with a slow charging current that is less than the maximum charging current, which is called slow charging. A certain mapping relationship between the maximum charging current and the slow charging current can be preset according to the user's usage needs and habits.

[0058] Furthermore, the target charging time is determined according to the current power of the terminal device, the preset cut-off power and the charging current that the energy supplement device can provide. For example, assuming that the current power of the terminal device is x%, the preset cut-off power is y%, the total battery capacity of the terminal device is C mAh, and the terminal device is charged with a charging current I, then the charging time required to charge from x% to y% is C(yx)% / I.

[0059] Step 303, determine the charging reminder time period according to the target charging time and the full charging time, and output the charging reminder information within the charging reminder time period. The time interval between the start time of the charging reminder time period and the departure time is the full charging time, and the time interval between the end time of the charging reminder time period and the departure time is the target charging time.

[0060] In some embodiments, the target charging time and the full charging time can be compared. When the target charging time is less than or equal to the full charging time, it means that it is still possible to remind the user to charge, so the charging reminder information is output within the charging reminder time period; if the target charging time is greater than the full charging time, it means that it is too late to fully charge even if reminded, so no reminder is given.

[0061] In a possible implementation, after the terminal device outputs the charging reminder information within the charging reminder time period, it will continue to determine whether the terminal device is connected to the charger, and use different charging modes when the charger is connected for charging. Figure 4 , is a flow chart of a charging reminder provided by another embodiment of the present application, such as Figure 4 As shown, the method may include the following steps 401 to 416:

[0062] It should be noted that, in this embodiment, the full charging time includes a first full charging time and a second full charging time, the target charging time includes a first charging time and a second charging time, and the charging reminder time period includes a first charging reminder time period and a second charging reminder time period.

[0063] Among them, the first full charging time is used to indicate the time required to charge the terminal device from zero power to a preset cut-off power at a first power, and the first charging time is used to indicate the time required to charge the terminal device from the current power to the preset cut-off power at a slow charging power, and both the first power and the slow charging power are less than the preset power threshold; the second full charging time is used to indicate the time required to charge the terminal device from zero power to the preset cut-off power at a second power, and the second charging time is used to indicate the time required to charge the terminal device from the current power to the preset cut-off power at a fast charging power, and both the second power and the fast charging power are greater than the preset power threshold.

[0064] Step 401, determining whether the first charging time is less than or equal to the first full charging time.

[0065] It should be noted that the terminal device calculates the time required to charge the terminal device from zero power to a preset cut-off power using the first power, obtains the first full charge time, and compares the first full charge time with the first charging time at the first detection moment with a time interval from the departure moment equal to the first full charge time, that is, determines whether the first charging time is less than or equal to the first full charge time. The first power is a standard power less than a preset power threshold, and the standard power can be determined based on the performance of the original charger of the terminal device.

[0066] In some embodiments, the slow charging power is determined based on the capability of the current charging device of the terminal device. The first charging duration is determined based on the product of the second charging duration and a preset coefficient, and the value of the preset coefficient is greater than 1, for example, it can be 1.3 to 2. Among them, the second charging duration is determined based on the ratio of the target power difference to the maximum charging current of the current charging device of the terminal device, and the target power difference is the difference between the preset cutoff power and the current power of the terminal device.

[0067] For example, assuming that the current power of the terminal device is x%, the preset cut-off power is y%, the total battery capacity of the terminal device is C mAh, and the maximum charging current is I max When charging the terminal device, the second charging time t2 required to charge from x% to y% is C(yx)% / I max , then the first charging time t1 = 1.3t2 ~ 2t2.

[0068] Step 402: when the first charging duration is less than or equal to the first full-charging duration, determine a first charging reminder time period, and output charging reminder information within the first charging reminder time period.

[0069] The time interval between the start time of the first charging reminder time period and the departure time is the first full charging time period, and the time interval between the end time of the first charging reminder time period and the departure time is the first charging time period.

[0070] When the first charging time is greater than the first full-charging time, step 411 is executed.

[0071] In some embodiments, if the first charging time is less than or equal to the first full charging time, it means that it is still possible to remind the user and charge the terminal device with the slow charging power or the first power, and it is also better for the battery; the time period for reminding the user to charge can be between the moment when the time interval from the departure time is the first full charging time and the moment when the time interval from the departure time is the first charging time.

[0072] Step 403: determine whether the terminal device is connected to a charger before the end time of the first charging reminder time period.

[0073] In some embodiments, after the terminal device outputs a charging reminder message within the first charging reminder time period, the user may not necessarily connect the charger in time. If it is not connected for a long time, the battery may not be fully charged before the departure time. Therefore, it is necessary to determine whether the terminal device is connected to the charger before the end of the first charging reminder time period, and take different measures according to the situation of the charger connection to meet user needs.

[0074] Step 404, when the terminal device is connected to the charger before the end of the first charging reminder time period, control the terminal device to enter the first charging mode, and the first charging mode is used to indicate that the terminal device is charged with a slow charging power.

[0075] If the terminal device is not connected to the charger before the end time of the first charging reminder time period, step 406 is executed.

[0076] In some embodiments, when the terminal device is connected to the charger before the end of the first charging reminder time period, the terminal device can be charged with a slow charging power to maximize the battery life because the charging time is early.

[0077] Step 405, when the terminal device enters the first charging mode, the target charging strategy is determined according to the current screen brightness, foreground and background application types, device temperature, system power consumption and current power of the terminal device, and the terminal device is charged based on the target charging strategy.

[0078] In some embodiments, a one-to-one mapping relationship between screen brightness, foreground and background application types, device temperature, system power consumption, current device power and charging strategy is preset in the terminal device. The terminal device compares the current screen brightness, foreground and background application types, device temperature, system power consumption and current device power with the mapping relationship stored locally or in the cloud to determine the target charging strategy and the corresponding first charging parameter. The first charging parameter includes the charging current and the charging temperature rise target. The temperature of the terminal device is continuously collected during the charging process, and the first charging parameter is updated with the temperature to obtain the second charging parameter. The temperature of the terminal device is continuously detected again, and the second charging parameter is updated again to obtain the third charging parameter, etc. If the terminal device exceeds the maximum temperature threshold during the charging process, the current charging plan is stopped and a new charging strategy is re-matched.

[0079] In some embodiments, the screen in the terminal device can be divided into an on screen and an off screen. In the case of an on screen, the screen brightness can be divided into low brightness, medium brightness and high brightness. Low brightness is when the battery level is less than 20%, which can be called type 1; medium brightness is when the battery level is between 20% and 75%, which can be called type 2; high brightness is when the battery level is higher than 75%, which can be called type 3.

[0080] For the foreground and background application types in the terminal device, the running applications can be classified and marked, including but not limited to the graphic information flow category, which can be called type 1; the video category, which can be called type 2; the video call category, which can be called type 3; and the game category, which can be called type 4.

[0081] For the device temperature of the terminal device, the battery temperature of the terminal device at the time of charging can be obtained, for example, the temperature data can be obtained by collecting the temperature through at least one temperature sensor arranged around the battery; when multiple sensor temperatures are arranged around the terminal battery, the battery temperature should be the average value of multiple temperature data obtained after collecting the temperature data through multiple temperature sensors. According to the different user sensations, the temperature is divided into normal temperature, such as TBAT[20, 30]T, which can be called type 1; medium temperature, such as TBAT[30, 40]T, which can be called type 2; higher temperature, such as TBAT[40, 47]T, which can be called type 3.

[0082] As for the system power consumption of the terminal device, since the battery voltage in the terminal device is constant, the system power consumption can be characterized by the current. To obtain the system power consumption, the output voltage (VBUS) and output current (IBUS) of the charger connected to the terminal device, as well as the input voltage (VBAT) and input current (IBAT) of the battery of the terminal device can be obtained first; then, the system power consumption of the electronic device can be determined based on the product of the output voltage and output current of the charger connected to the terminal device, the product of the input voltage and input current of the battery of the terminal device, and the charging efficiency. For example, if the charging efficiency is Among them, I out is the output current of the charging chip during discharge, T out is the time of discharge to cut-off voltage, I in is the charging current, T in is the charging time; the charging efficiency can be calculated based on the historical charging data of the electronic device, so the system power consumption

[0083] The current power level of the terminal device can be obtained through the charging device, and is divided into BAT [0, 20]%, which can be called low power mode, type 1, BAT [20, 50]%, which can be called medium power mode, type 2, and BAT [50, 90]%, which can be called high power mode, type 3, based on the power threshold and the low power threshold.

[0084] For example, assuming that the current parameters of the terminal device are: screen brightness is 60% of medium brightness, foreground application type is type 1, device temperature TBAT is 32°C, system power consumption is 630mA, and device current power BAT is 35%, then charging scenario 1, charging scenario 2, and charging scenario 3 can be obtained from the cloud or locally, and each charging scenario includes a reference information and a charging strategy. As an example, the reference information is as follows:

[0085] Charging scenario 1: foreground application type (type 1), screen brightness low brightness, TBAT [20,30] degrees Celsius (type 1), system power consumption [600,700] mA, BAT [0,20] % (type 1).

[0086] Charging scenario 2: foreground application type (type 1), screen brightness medium brightness, TBAT [30,40] degrees Celsius (type 2), system power consumption [600,700] mA, BAT [20,50] % (type 2).

[0087] Charging scenario 3: foreground application type (type 3), screen brightness low brightness, TBAT [20,30] degrees Celsius (type 1), system power consumption [700,800] mA, BAT [50,90] % (type 3).

[0088] Among them, the current parameters of the terminal device are matched with the reference information in sequence to obtain charging scenario 2, and the corresponding charging strategy is the target charging strategy.

[0089] Step 406: When the terminal device is not connected to the charger before the end time of the first charging reminder time period, determine whether the second charging duration is less than or equal to the second full charging duration.

[0090] It should be noted that the terminal device calculates the time required to charge the terminal device from zero power to a preset cut-off power using the second power, obtains the second full charge time, and compares the second full charge time with the second charging time at a second detection time interval from the departure time equal to the second full charge time. The second power is a standard power greater than a preset power threshold, and the standard power can be determined based on the performance of the original charger of the terminal device.

[0091] Among them, the second charging time is determined according to the ratio of the target power difference to the maximum charging current of the current charging device of the terminal device, and the target power difference is the difference between the preset cut-off power and the current power of the terminal device.

[0092] For example, assuming that the current power of the terminal device is x'%, the preset cut-off power is y%, the total battery capacity of the terminal device is C mAh, and the maximum charging current I max When charging the terminal device, the second charging time t'2 required to charge from x'% to y% is C(y-x')% / I max .

[0093] Step 407: when the second charging duration is less than or equal to the second full-charging duration, determine a second charging reminder time period, and output charging reminder information within the second charging reminder time period.

[0094] The time interval between the start time of the second charging reminder time period and the departure time is the second full charging time period, and the time interval between the end time of the second charging reminder time period and the departure time is the second charging time period.

[0095] When the second charging time is greater than the second full-charging time, step 416 is executed.

[0096] In some embodiments, if the second charging time is less than or equal to the second full charging time, it means that it is still possible to remind the user and charge the terminal device with the fast charging power or the second power; the time period for reminding the user to charge can be between the moment when the time interval from the departure time is the second full charging time and the moment when the time interval from the departure time is the second charging time.

[0097] Step 408: Determine whether the terminal device is connected to a charger before the end time of the second charging reminder time period.

[0098] In some embodiments, after the terminal device outputs a charging reminder message within the second charging reminder time period, the user may not necessarily connect the charger in time. If it is not connected for a long time, the battery may not be fully charged before the departure time. Therefore, it is necessary to determine whether the terminal device is connected to the charger before the end of the second charging reminder time period, and take different measures according to the situation of the charger connection to meet user needs.

[0099] Step 409, when the terminal device is connected to the charger before the end of the second charging reminder time period, the terminal device is controlled to enter the second charging mode, and the second charging mode is used to indicate that the terminal device is charged with a fast charging power.

[0100] Step 410, when the terminal device enters the second charging mode, a target charging strategy is determined according to the current screen brightness, foreground and background application types, device temperature, system power consumption and current power of the device, and the terminal device is charged based on the target charging strategy.

[0101] In some embodiments, a one-to-one mapping relationship between screen brightness, foreground and background application types, device temperature, system power consumption, current device power and charging strategy is preset in the terminal device. The terminal device determines the target charging strategy and corresponding charging parameters based on the current screen brightness, foreground and background application types, device temperature, system power consumption and current device power compared with the mapping relationship stored locally or in the cloud.

[0102] It should be noted that in this step, the method for determining the target charging strategy by comparing the terminal device's current screen brightness, foreground and background application types, device temperature, system power consumption, and current power of the device with the mapping relationship between local or cloud storage can refer to the description in step 405, and the repeated parts will not be repeated here.

[0103] As an example, see Figure 5 , is a schematic diagram of a charging algorithm matching process provided by an embodiment of the present application. Figure 5As shown, the terminal device connects to the charger and starts charging, and can determine whether to enter the first charging mode or the second charging mode according to the time of connecting to the charger. The first charging mode is divided into screen-on charging and screen-off charging. Screen-off charging uses a slow charging algorithm to determine the target charging mode according to the current foreground and background application types, device temperature, system power consumption and current power of the device of the terminal device; screen-on charging uses a slow charging algorithm to determine the target charging mode according to the current screen brightness, foreground and background application types, device temperature, system power consumption and current power of the device of the terminal device. Correspondingly, the second charging mode is divided into screen-on charging and screen-off charging. Screen-off charging uses a fast charging algorithm to determine the target charging mode according to the current foreground and background application types, device temperature, system power consumption and current power of the device of the terminal device; screen-on charging uses a fast charging algorithm to determine the target charging mode according to the current screen brightness, foreground and background application types, device temperature, system power consumption and current power of the device of the terminal device.

[0104] Step 411, when the first charging duration is greater than the first full charging duration, no charging reminder information is output during the first charging reminder time period, and it is determined whether the second charging duration is less than or equal to the second full charging duration.

[0105] Step 412: when the second charging duration is less than or equal to the second full-charging duration, determine a second charging reminder time period, and output charging reminder information within the second charging reminder time period.

[0106] The time interval between the start time of the second charging reminder time period and the departure time is the second full charging time period, and the time interval between the end time of the second charging reminder time period and the departure time is the second charging time period.

[0107] When the second charging time is greater than the second full-charging time, step 416 is executed.

[0108] For this step, please refer to the description of step 407, which will not be repeated here.

[0109] Step 413, determining whether the terminal device is connected to a charger before the end time of the second charging reminder time period.

[0110] This step may refer to the description of step 408 and will not be repeated here.

[0111] Step 414, when the terminal device is connected to the charger before the end of the second charging reminder time period, control the terminal device to enter the second charging mode, and the second charging mode is used to indicate that the terminal device is charged with a fast charging power.

[0112] Step 415, when the terminal device enters the second charging mode, the target charging strategy is determined according to the current screen brightness, foreground and background application types, device temperature, system power consumption and current power of the terminal device, and the terminal device is charged based on the target charging strategy.

[0113] In some embodiments, a one-to-one mapping relationship between screen brightness, foreground and background application types, device temperature, system power consumption, current power level of the device and charging strategy is preset in the terminal device.

[0114] This step may refer to the description of step 410 and will not be repeated here.

[0115] Step 416: When the second charging time is longer than the second full-charging time, no charging reminder information is output during the second charging reminder time period.

[0116] In this embodiment, the terminal device first obtains the trip information of the terminal device, which includes the departure time, and then determines the target charging time according to the current power of the terminal device and the preset cut-off power. The target charging time is used to indicate the time required to charge the terminal device from the current power to the preset cut-off power. Finally, according to the target charging time and the full charging time, the charging reminder time period is determined, and the charging reminder information is output within the charging reminder time period. Furthermore, after the terminal device outputs the charging reminder information within the charging reminder time period, it will continue to determine whether the terminal device is connected to a charger, and adopt different charging modes when the charger is connected for charging. By combining the itinerary information, current power and preset cut-off power of the terminal device, the time required for the device to be charged can be accurately predicted, thereby avoiding the use experience affected by low power or overcharging, and improving the battery use efficiency of the device; by determining the target charging time and the charging reminder time period, the device can issue a charging reminder at the best time, thereby avoiding the sudden power outage of the device caused by the user ignoring the power problem, effectively improving the reliability of the device and the user's use experience; after detecting whether the charger is connected, the terminal device can adjust according to different charging modes, which may include fast charging, slow charging and other modes. The switching of different modes can optimize the charging speed and battery life according to the battery condition; the user can charge in time according to the charging reminder information of the device, avoiding the situation of suddenly stopping the use of the device when the power is low, especially when the itinerary is tight, the user can flexibly arrange the charging time according to the charging needs of the device, which improves the convenience; intelligent control of factors such as charging mode and charging time helps to avoid overcharging or over-discharging, thereby extending the service life of the battery and reducing the risk of battery loss; in general, the charging reminder method in this embodiment not only improves the use efficiency of the terminal device through intelligent power management and charging reminders, but also optimizes the charging process, which has a positive impact on the battery protection and user experience of the device.

[0117] As an example, travel information is obtained from the user terminal side to detect whether the user is about to travel, and then corresponding reminder information is generated to remind the user to charge during the first / second reminder time period. The sending time of the reminder can be determined by the charging efficiency of the charger most commonly used by the user at the first / second detection moment; and according to the different timing when the user connects to the charger after receiving the charging reminder, corresponding charging algorithms are allocated to match the user's usage requirements as much as possible on the premise of extending the battery life.

[0118] Among them, the travel information may include the target time for the user to reach the destination. For example, if the user needs to arrive at the airport at 7 pm, the target time is 7 pm. After the user authorizes the use of relevant materials, the terminal device is used to obtain the user's commonly used travel modes, such as self-driving, taking a taxi, public transportation, bicycle, walking, etc., to calculate the time t0 required for the user to travel from the current location to the corresponding airport using the commonly used travel mode. Then, the time interval between the first detection moment when the device reminds the user to charge and the target time is T1 = t0 + ah, and the time interval between the second detection moment when the device reminds the user to charge and the target time is T2 = t0 + bh, where b < a, which can be gradually adjusted through later research, and specific values are not limited here. ah is the time required to fully charge the terminal device from zero power to full power with a preset standard slow charge, and bh is the time required to fully charge the terminal device from zero power to full power with a preset standard fast charge. Assume that the current battery level of the terminal device at the first detection moment is x%, the preset cut-off battery level is y%, and the total battery capacity of the terminal device is C mAh, with the maximum charging current I max charges the terminal device, then the second charging duration t2 required to charge from x% battery level to y% is C(y - x)% / I max , then the first charging duration t1 = 1.3t2 - 2t2. Assume that the current battery level of the terminal device at the second detection moment is x'%, the preset cut-off battery level is y%, and the total battery capacity of the terminal device is C mAh, with the maximum charging current I max charges the terminal device, then the second charging duration t'2 required to charge from x'% battery level to y% is C(y - x')% / I max .

[0119] Furthermore, the time interval between the start moment of the first reminder time period and the target time is T1, and the time interval between the end moment of the first reminder time period and the target time is the first charging duration t1; the time interval between the start moment of the second reminder time period and the target time is T2, and the time interval between the end moment of the second reminder time period and the target time is the second charging duration t'2. Please refer to Figure 6 , for the overall exemplary flowchart of the charging reminder method provided by an embodiment of the present application, as Figure 6 shown, the method may include the following steps 601 to step 615:

[0120] Step 601, obtaining travel information.

[0121] Step 602: Generate corresponding travel reminder information, which includes the target time.

[0122] It should be noted that the target time in this embodiment is different from the above Figure 4 The departure time in the illustrated embodiment is not the same time. For example, if the user needs to arrive at the airport at 7 pm, then 7 pm is the target time. If the user needs to take a taxi for 1 hour from home to the airport, the user should leave home at 6 pm, then 6 pm is the departure time. In actual use, both the target time and the departure time can be used for estimation. In this embodiment, the target time is used as an example for explanation.

[0123] Step 603 , determining whether the first charging time t1 is within ah at the first detection moment, if the first charging time t1 is within ah, executing step 604 ; otherwise executing step 611 .

[0124] Step 604: output charging reminder information within the first reminder time period.

[0125] Step 605 , determining whether the terminal device is connected to the charger within the first reminder time period. If the terminal device is connected to the charger within the first reminder time period, executing step 606 , otherwise executing step 607 .

[0126] Step 606, entering the first charging mode.

[0127] Step 607: Refresh the current power of the terminal device at the second detection time to obtain x'%.

[0128] Step 608, at the second detection time, determine whether the second charging time t'2 is within bh. If the second charging time t'2 is within bh, execute step 609; otherwise, execute step 615.

[0129] Step 609: output charging reminder information within the second reminder time period.

[0130] Step 610: When the terminal device is connected to a charger, enter a second charging mode.

[0131] Step 611: Do not remind the user to charge during the first reminder period, and refresh the current power of the terminal device at the second detection time to obtain x'%.

[0132] Step 612, at the second detection time, determine whether the second charging time t'2 is within bh. If the second charging time t'2 is within bh, execute step 613; otherwise, execute step 615.

[0133] Step 613: output charging reminder information within the second reminder time period.

[0134] Step 614: When the terminal device is connected to a charger, enter the second charging mode.

[0135] Step 615: Do not output charging reminder information during the second reminder time period.

[0136] It should be noted that the specific implementation of the method in this embodiment can refer to the above Figure 3 and Figure 4 The embodiments shown in this application will not be described in detail here.

[0137] To sum up, the charging reminder method provided in the embodiment of the present application can avoid reminding users to charge too early and causing users to forget to charge, thereby improving the flexibility of charging reminders, and reminding users to charge at a time that matches the user's travel arrangements as much as possible, and matching different charging algorithms according to the time when the user's charger is inserted, thereby minimizing the loss of battery life.
