Description

Technical Field

[0001] The present invention relates to the field of intelligent charging, and in particular to a power bank and an intelligent charging method thereof. Background Art

[0002] As a portable mobile charging product, power banks are widely used in life. Existing electronic devices and power banks usually support high-power charging mode to quickly charge, but if this charging mode is used for a long time, the battery life and capacity of the power bank or electronic device will be reduced.

[0003] When charging smart devices, existing power banks align the charging protocol with the electronic device and then directly use the maximum power allowed by the power bank and the charging protocol to charge. When the power bank is used frequently, since the charging power of each charge is very high, in some scenarios where fast charging is not required, the power bank still uses the maximum power to charge the electronic device. In the long run, this will reduce the battery life and capacity of the power bank and the electronic device. Summary of the invention

[0004] Based on this, the purpose of the present invention is to overcome the defects or shortcomings of the prior art and provide an intelligent charging method for a power bank.

[0005] A smart charging method for a power bank comprises the following steps:

[0006] S1: The power bank obtains the user's charging information for the past N days from the electronic device;

[0007] S2: Determine the slow charging period based on the user's charging information over the past N days;

[0008] S3: Adjust the charging power of the power bank to slow charging or fast charging according to whether the current time is in the slow charging period. If the current time is in the slow charging period, the power bank charges the electronic device with the slow charging power. If the current time is not in the slow charging period, the power bank charges the electronic device with the fast charging power.

[0009] The smart charging chip on the power bank analyzes the charging information of the user on the electronic device over the past N days to determine the slow charging period, and then adjusts the charging power of the power bank to the electronic device based on whether the current time is in the slow charging period, thereby protecting the batteries of the power bank and the electronic device.

[0010] Furthermore, the step S2 comprises the following steps:

[0011] S21: Determine whether there is a period of time on the Nth day before today where the charging time is greater than or equal to L hours. If so, execute step S22; otherwise, execute step S3;

[0012] S22: Determine whether the charging start time of each day from today to the Nth day is within T1 hours before or after the charging start time on the Nth day when the charging duration is greater than or equal to L hours, and whether the charging end time of each day from today to the Nth day is within T2 hours before or after the charging end time on the Nth day when the charging duration is greater than or equal to L hours. If both are true, set the period as a slow charging period; otherwise, execute step S3.

[0013] Determine whether the user has charged the battery in a similar time period every day in the past N days, and the charging time is greater than L hours. If so, it is determined that the user is accustomed to charging for a long time during this period. If fast charging is used, the user's electronic device will be fully charged in a short time, thereby damaging the battery life and failing to fully utilize the user's accustomed plug-in time. Therefore, this period is set as the slow charging period to protect the user's electronic device and the battery of the power bank.

[0014] Furthermore, step S3 includes the following steps:

[0015] S31: Determine whether the current time is in the slow charging period, if the current time is in the slow charging period, execute step S32, if the current time is not in the slow charging period, execute step S33C;

[0016] S32: Determine whether the electronic device can be fully charged at the end of the slow charging period if the device is still being charged at the slow charging power; if not, execute step S33A; if yes, execute step S33B;

[0017] S33A: Determine whether the electronic device can be fully charged at the end of the slow charging period according to the fast charging power. If so, charge it according to the power that can be fully charged at the end of the slow charging period. If not, execute step S33C;

[0018] S33B: charging according to the slow charging power;

[0019] S33C: Charge according to the fast charge power.

[0020] Whether to use slow charging power is determined by whether the user's current plug-in time is within the slow charging period. At the same time, in order to make full use of the user's accustomed plug-in time, the charging power is intelligently adjusted according to the user's power level when plugging in and the length of time until the end of the slow charging period, so that the user can be fully charged as much as possible at the end of the slow charging period.

[0021] Further, it also includes steps S4, S5 and S6;

[0022] S4: During the charging process, continuously determine whether the user manually changes the charging power to slow charging or fast charging. If yes, execute step S5; otherwise, execute step S6;

[0023] S5: Charge with fast charge or slow charge according to user settings;

[0024] S6: Determine whether the current power is fully charged. If it is fully charged, end the charging. If not, continue to execute step S4.

[0025] If users have special needs, they can adjust the charging power to adapt to different situations.

[0026] Furthermore, the charging information acquired in step S1 includes the charging time periods of the user in the past N days and the charging upper limit set by the user;

[0027] The step S32 is: if the electronic device is currently being charged at the slow charging power, whether it can be charged to the upper limit set by the user at the end of the slow charging period; if not, executing step S33A; if yes, executing step S33B;

[0028] The step S33A is: determining whether the electronic device can be fully charged at the end of the slow charging period according to the fast charging power, and if so, charging according to the power that can be charged to the charging upper limit set by the user at the end of the slow charging period, and if not, executing step S33C;

[0029] The step S6 is: determining whether the current power reaches the charging upper limit set by the user, if so, ending the charging, if not, continuing to execute step S4.

[0030] When the power level of an electronic device remains above 80% for a long time, the battery life will be reduced to a certain extent. Users can define the upper limit of the charge level of the electronic device to protect the battery.

[0031] Furthermore, the charging information acquired in step S1 also includes the user's current location and the user's frequently used locations; step S6 includes the following steps:

[0032] S61: Determine whether the charging upper limit set by the user is 100%, if not, execute step S62A, if yes, execute step S62B;

[0033] S62A: Determine whether the current power reaches the charging upper limit set by the user, if yes, terminate the charging, if no, continue to step S4;

[0034] S62B: Determine whether the user's current location is at the user's common location, if not, execute step S62A, if yes, execute step S63;

[0035] S63: Determine whether the user's current power level has reached 80%, if yes, execute step S7, if no, execute step S4;

[0036] S7: Enable optimized charging mode to maintain the current charge level at 80%.

[0037] In order to prevent the battery life of electronic devices from being reduced due to the battery level being above 80% for a long time, the power bank can intelligently determine whether the user is currently in a common location, such as home, work, school, etc., and whether the charging limit set by the user is 100% to determine whether to enable the optimized charging mode to maintain the battery level at 80% to protect the battery.

[0038] Furthermore, the frequently used locations in steps S1 and S62B may be locations set by the user himself, and / or frequently used locations inferred by the power bank based on the user's location information. The user may define frequently used locations, or the power bank may infer frequently used locations based on the location track of the user's electronic device over the past N days.

[0039] Furthermore, the step S7 further includes the following steps:

[0040] S71: Whether the user chooses to charge immediately, if not, execute step S72A, if yes, execute step S72B;

[0041] S72A: stop charging, and continue to execute step S71;

[0042] S72B: Charge according to the fast charging power; S73: Determine whether the current power reaches 100%, if not, continue to execute step S72B, if yes, end charging.

[0043] When in optimized charging mode, the user can choose to charge to 100% immediately to end optimized charging mode, so as to quickly charge the electronic device from 80% to 100%.

[0044] Furthermore, before step S1, the step of determining whether the user has selected the protection charging mode is also included. If so, step S1 is executed. Otherwise, the battery is fully charged with fast charging power. The user can choose whether to enable the protection charging mode to functionally adjust the power of the power bank to charge the electronic device, thereby improving the user experience.

[0045] Furthermore, the number of days N, charging time L, floating threshold T1 of the start time of charging, and floating threshold T2 of the end time of charging in steps S1 and S2 are adjustable parameter values ​​in the power bank, which can be adjusted according to different actual conditions. According to the different actual use of the power bank by each user, the parameter values ​​N, L, T1, and T2 for the power bank to judge the slow charging period can be adjusted to meet the different needs of different users.

[0046] A power bank comprises a power bank body, a charging cable and an intelligent charging chip. The power bank body can be connected to an electronic device via the charging cable for charging and data transmission, and the intelligent charging chip can execute the above-mentioned intelligent charging method.

[0047] A power bank comprises a power bank body, a charging cable and an intelligent charging chip. The power bank body can be connected to an electronic device via the charging cable for charging and can perform data transmission with the electronic device via wireless communication. The intelligent charging chip can execute the above-mentioned intelligent charging method.

[0048] For better understanding and implementation, the present invention is described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] Figure 3 The specific flow chart of the intelligent charging method of the power bank. DETAILED DESCRIPTION

[0052] In order to solve the problem that the existing power bank will charge the electronic device and the power bank by default at the maximum power allowed by the electronic device and the power bank, so that long-term and high-frequency use may reduce the battery life of the power bank and the e-book device. The present invention designs a power bank and an intelligent charging method thereof, which obtains the charging information and setting information of the user's electronic device in the past N days to intelligently determine how much power is needed for the current charging, and use low power for long-term charging, thereby protecting the user's electronic device and the battery of the power bank.

[0053] Based on the above-mentioned design of the smart charging solution for the power bank, the present invention designs a power bank, including a power bank body, a charging cable and a smart charging chip; the power bank body can be connected to an electronic device via the charging cable, and transmit data with the electronic device via the charging cable or wireless communication; the smart charging chip is arranged in the power bank body, and can process user data transmitted back by the electronic device from the charging cable, and make judgments based on the data to adjust the charging power when the power bank charges the user's electronic device.

[0054] For details, please participate Figure 1 , Figure 2 and Figure 3 ,in Figure 1 This is a module diagram of the smart charging chip of the power bank. Figure 3The intelligent charging chip is provided with: an information acquisition module 1, a slow charging period determination module 2, an intelligent charging power adjustment module 3, a manual charging power setting module 4 and an optimized charging module 5.

[0055] The information acquisition module 1 is used to execute step S1: obtain the charging information of the user in the past N days from the electronic device. The charging information includes the charging time period of the user in the past N days, the charging upper limit of the electronic device set by the user, and the user's common places. Wherein N is an adjustable parameter value, and the user can adjust the size of N through software to adapt to different user needs. For example, in this embodiment, N is set to 7 days; the charging upper limit is the charging power upper limit set by the user on the electronic device, and it can also be the charging upper limit of the electronic device set by the user on the power bank; the user's common places can be the places set by the user on the electronic device or on the power bank through software, and / or the common places calculated by the power bank based on the user's location information in the past N days, such as home, company, school and other places. The intelligent charging chip on the power bank processes this information to determine the charging power that is currently suitable for the user.

[0056] The slow charging period determination module 2 is used to execute step S2, and step S2 includes the following steps:

[0057] S21: Determine whether there is a period of time on the Nth day before today with a charging duration greater than or equal to L hours. If so, execute step S22; otherwise, execute step S3.

[0058] S22: Determine whether the charging start time of each day from today to the Nth day is within T1 hours before or after the charging start time on the Nth day when the charging duration is greater than or equal to L hours, and whether the charging end time of each day from today to the Nth day is within T2 hours before or after the charging end time on the Nth day when the charging duration is greater than or equal to L hours. If both are true, set the period as a slow charging period; otherwise, execute step S3.

[0059] Specifically, the calculation expressions of steps S21 and S22 are as follows:

[0060] like:

[0061] And: |S N-i -S N |≤T1...(i=1,2,3,...,N-1)

[0062] And: |E N-i -E N |≤T2...(i=1,2,3,...,N-1)

[0063] Then set this period as the slow charging period.

[0064] In the formula, E N Represents the end time of charging N days before today, E N-i Represents the end time of charging Ni days before today; S N Represents the charging start time N days before today, S N-i Represents the charging start time of the Ni day before today; L represents the charging duration, T1 and T2 represent the floating threshold of the charging start time point and the receiving charging time point respectively, L, T1, T2 are adjustable parameters in the smart charging chip of the power bank, and users can adjust the parameters in the software according to their charging habits to adapt to different charging situations. In this embodiment, L is set to 7 hours, and T1 and T2 are set to 1 hour.

[0065] Based on the above formula, it is judged whether the user is accustomed to charging for a long period of time, and the long period is set as a slow charging period to prevent the user from fully charging the electronic device in a short time through fast charging during this period, thereby making full use of the time when the user plugs in the electronic device to protect the mobile phone battery.

[0066] The intelligent charging power adjustment module 3 is used to execute step S3, and step S3 includes the following steps:

[0067] S31: Determine whether the current time is in the slow charging period. If the current time is in the slow charging period, execute step S32; if the current time is not in the slow charging period, execute step S33C.

[0068] S32: Determine whether the electronic device can be charged to the charging upper limit set by the user at the end of the slow charging period if charging is currently continued at the slow charging power; if not, execute step S33A; if yes, execute step S33B.

[0069] S33A: Determine whether the electronic device can be fully charged at the end of the slow charging period according to the fast charging power. If so, charge it according to the power that can be charged to the charging upper limit set by the user at the end of the slow charging period. If not, execute step S33C.

[0070] S33B: Charge according to the slow charging power.

[0071] S33C: Charge according to the fast charge power.

[0072] Whether to use slow charging power is determined by whether the time when the user currently plugs in the power bank is within the slow charging period. At the same time, in order to make full use of the time when the user continues to charge for a long time, the charging power is intelligently adjusted according to the power level when the user plugs in and the length of time until the end of the slow charging period, so that the user can be fully charged as much as possible at the end of the slow charging period.

[0073] The manual charging power setting module 4 is used to execute step S4: continuously determine whether the user manually changes the charging power to slow charging or fast charging during the charging process, if so, execute step S5, if not, execute step S6.

[0074] S5: Charge using fast charging or slow charging according to the charging power set by the user.

[0075] If the user has special needs, such as suddenly having to go out for an emergency and needing to charge quickly, the user can adjust the charging power by himself to adapt to different situations.

[0076] The optimized charging module is used to perform steps S6 and S7, and step S6 includes the following steps:

[0077] S61: Determine whether the charging upper limit set by the user is 100%, if not, execute step S62A, if yes, execute step S62B.

[0078] S62A: Determine whether the current power reaches the charging upper limit set by the user. If so, terminate the charging. If not, continue to execute step S4.

[0079] S62B: Determine whether the user's current location is at the user's frequently used location. If not, execute step S62A. If yes, execute step S63.

[0080] S63: Determine whether the user's current power level has reached 80%, if so, execute step S7, if not, execute step S4.

[0081] The step S7 comprises the following steps:

[0082] S71: Whether the user chooses to charge immediately, if not, execute step S72A, if yes, execute step S72B;

[0083] S72A: Stop charging and continue to execute step S71.

[0084] S72B: Charge according to the fast charge power.

[0085] S73: Determine whether the current power level has reached 100%. If not, continue to execute step S72B. If yes, end charging.

[0086] In order to prevent the battery life of electronic devices from being degraded due to the power level of electronic devices being above 80% for a long time, the power bank can intelligently determine whether the user is currently in a common location, such as home, work, school, etc., and whether the charging limit set by the user is 100% to determine whether to enable the optimized charging mode. When the user is in a common location, the user will stay in the current location for a long time and has no need to go out for the time being; at this time, the battery power is maintained at 80% to protect the battery. At the same time, when in the optimized charging mode, the user can choose to charge to 100% immediately to end the optimized charging mode. When the user needs to go out, the power of the electronic device can be easily and quickly charged from 80% to 100%.

[0087] Preferably, before executing step S1, the smart charging chip first executes the following steps: determining whether the user chooses to enable the protection charging mode, if yes, executing step S1, otherwise directly using the fast charging power to fully charge the electronic device. This improves the user experience, and the user can independently choose whether to need the power bank to help him choose the charging power.

[0088] Compared with the existing power bank, the present invention analyzes the charging information of the user on the electronic device for the past N days through the intelligent charging chip on the power bank, thereby determining the slow charging period, and then adjusting the charging power of the power bank to the electronic device according to whether the current time is in the slow charging period, thereby protecting the battery of the power bank and the electronic device. It also provides adjustable parameter values, and users can customize parameter values ​​to adjust the judgment basis of the power bank for the slow charging period. It also provides an optimized charging mode to prevent the user's electronic device from being charged more than 80% for a long time, thereby protecting the battery.

[0089] Based on the same inventive concept, the present application also provides an electronic device, which may be a terminal device such as a server, a desktop computing device or a mobile computing device (e.g., a laptop computing device, a handheld computing device, a tablet computer, a netbook, etc.). The device includes one or more processors and a memory, wherein the processor is used to execute a program to implement the intelligent charging method of the power bank in the embodiment of the present invention; and the memory is used to store a computer program executable by the processor.

[0090] Based on the same inventive concept, the present application also provides a computer-readable storage medium, corresponding to the embodiment of the aforementioned intelligent charging method of a power bank, wherein the computer-readable storage medium stores a computer program thereon, and when the program is executed by a processor, the steps of the intelligent charging method of the power bank recorded in any of the aforementioned embodiments are implemented.

[0091] The present application may take the form of a computer program product implemented on one or more storage media (including but not limited to disk storage, CD-ROM, optical storage, etc.) containing program code. Computer-usable storage media include permanent and non-permanent, removable and non-removable media, and information storage can be achieved by any method or technology. Information can be computer-readable instructions, data structures, modules of programs, or other data. Examples of computer storage media include but are not limited to: phase change memory (PRAM), static random access memory (SRAM), dynamic random access memory (DRAM), other types of random access memory (RAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), flash memory or other memory technology, read-only compact disk read-only memory (CD-ROM), digital versatile disk (DVD) or other optical storage, magnetic cassettes, tape disk storage or other magnetic storage devices or any other non-transmission medium that can be used to store information that can be accessed by a computing device.

[0092] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, and the present invention is also intended to include these modifications and modifications.
