[0051] Figure 2 is the schematic diagram of the reset button of the method of the present application;

[0052] Figure 3 is the schematic diagram of the pressure plate of the method of the present application. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0053] The following further describes the present application in detail with reference to the attached... Figures 1 - 3 The present application is further described in detail as follows.

[0054] The embodiment of the present application discloses a control method of a power bank with switchable charging power.

[0055] Refer to... Figure 1 And... Figure 2 The control method of the power bank with switchable charging power includes:

[0056] Step 1. Establish a control basis, which includes:

[0057] S11. Establish a data connection relationship with the cloud platform of the power bank rental operator; wherein, the cloud platform is used to obtain Bluetooth information from the mobile phone when receiving a power bank usage request from the user, bind the ID of the power bank to be rented, and output it to the power bank corresponding to the ID and the corresponding target mobile phone;

[0058] In this embodiment, the power bank is a shared power bank, and the cloud platform is set by the power bank operator. For example, the shared power bank put into use / operated by a certain group. As an electronic device, each power bank is paired with a unique ID during production, and the ID is uploaded to the cloud platform for registration and binding; after the user scans the QR code on the charging bin, a rental page will appear on the mobile phone. By selecting the option to rent a power bank, a usage request for renting a power bank is sent to the cloud platform (it should be noted that when the user selects the option to rent a power bank, the cloud platform obtains the Bluetooth authorization of the mobile phone).

[0059] Step 2. Establish a control logic, which includes:

[0060] S21. If the Bluetooth information of the target sent by the cloud platform is received, establish a data connection with the target mobile phone;

[0061] S22. Obtain the electrical parameters of several modules in the mobile phone, and analyze the power consumption based on the electrical parameters and accumulate to obtain the real-time power consumption and define it as a1; wherein, the modules include CPU, GPU, display screen, etc. The power bank reads and calls the electrical parameters of several modules in the mobile phone from the charging management module of the mobile phone through Bluetooth, and calculates the power consumption through a formula. The electrical parameters include current, voltage, etc.:

[0062] P = U × I

[0063] Wherein, P is the power consumption, U is the voltage, and I is the current. Example: If the current voltage of the CPU module is 1.2V and the current is 4A, the power consumption of the CPU module can be obtained through the above formula:

[0064] 1.2 × 4 = 4.8W

[0065] S23. Compare the accumulated power consumption value a1 with the preselected large power consumption standard threshold;

[0066] S24. If the real-time power consumption is greater than the large power consumption standard threshold, it meets the preset overheating risk condition, switch the charging mode of the power bank to the low power mode, and make the interaction unit preset on the outer shell of the power bank display the charging power; wherein, the real-time power consumption is the accumulated value a1 of the power consumption of the mobile phone currently obtained by the power bank.

[0067] In the above method, the power bank obtains the voltage of low-power charging set during the production of the power bank through the cloud platform, and controls the buck converter to reduce the charging voltage of the power bank through the microcontroller preset in the power bank. The interaction unit includes at least a display. Considering cost and function here, a simple LED display can be used, and the power mode (for example: high power, low power, which can be represented by characters) is displayed on the display; it should be noted that the interaction unit also includes buttons, etc., which will be specifically elaborated below.

[0068] S25. Obtain the interaction information input by the user to the power bank during the charging process;

[0069] S26. If a signal to reset the charging power of the power bank appears in the interaction information, disconnect the data connection between the power bank and the mobile phone, and reset the charging behavior of the power bank to high-power priority.

[0070] It should be noted that after the power bank is connected to the mobile phone via Bluetooth, through the intervention of the cloud platform, the electrical parameter data of several modules of the mobile phone is read and called, rather than direct data sharing and access between the power bank and the mobile phone, avoiding potential safety hazards when the power bank directly obtains the data of the mobile phone and protecting the privacy and security of users.

[0071] According to the above content, this method can:

[0072] 1. Obtain the electrical parameters of several modules in the mobile phone and analyze them, judge the usage status of the mobile phone based on the analysis results, and switch the charging mode of the power bank;

[0073] 2. Receive the interaction information feedback by the user and reset the charging behavior of the power bank accordingly.

[0074] In an embodiment of this method, before switching the charging mode of the power bank to the low-power mode, it further includes:

[0075] S31. Search the preset database according to the model of the mobile phone to obtain the standard charging power matching the model of the mobile phone, and define it as P1; where the model of the mobile phone is the model of the mobile phone obtained by the cloud platform when the mobile phone sends a power bank usage request; the database is set up by the back-end staff, which stores the working parameters, configurations and related data of various models of mobile phones on the market, and the working parameters at least include charging power, charging protocol, etc.

[0076] S32. Calculate the charging time based on the start time of charging and the current time; example: the start time of charging is t0, and the current time is t9, then the charging time is t9 - t0, that is, if the start time of charging t0 is 17:00 and the current time t9 is 19:00, the charging time can be obtained as 2h.

[0077] S33. Estimate the charging amount Q1 based on the charging power P1, the voltage of the mobile phone, and the charging time. Among them, the charging amount Q1 is calculated and obtained through the formula:

[0078]

[0079] Among them, Q is the charging quantity, P is the charging power P1, T is the charging time, V is the voltage of the mobile phone. If the charging power P is 18W, the charging time T is 1.5h, and the battery voltage V is 3.7V, then it can be calculated from the above formula:

[0080]

[0081] S34. If the charging amount Q1 reaches the pre-set emergency power threshold Q2, and currently meets the pre-set overheating risk conditions, then switch the charging mode of the power bank to the low-power mode. The emergency power threshold Q2 is to provide a certain amount of power for the mobile phone to ensure that the mobile phone can maintain user use for a period of time after being separated from the power bank. The emergency power threshold Q2 is uniformly set for the power bank during the production of the power bank.

[0082] According to the above method, it can be known that this method can maintain the user's short-term use of the power bank and then continue to perform high-power consumption behaviors, preventing the charging amount from being too small in the low-power mode during short-term charging, resulting in the situation that the battery power of the user's mobile phone is still insufficient.

[0083] In an embodiment of this method, it further includes:

[0084] S41. Obtain the predicted charging end time t1 and the predicted power D actively filled in by the user based on the cloud platform. Among them, after the user scans the QR code on the charging bin, in the page generated on the mobile phone, there are options for the user to fill in the predicted end time t1 and the predicted power D. Among them, the predicted power D is the power that the user expects the mobile phone to increase after charging ends at t1. Example: When the initial power is 15%, the user fills in 15:00 in the predicted end time t1, and the predicted power D is 30%. Then when the charging ends, the predicted mobile phone power is 45%.

[0085] S42. Calculate the duration T2, and T2 = predicted charging end time t1 - charging start time t0;

[0086] S43. If the duration T2 is greater than the predicted minimum duration T3, then perform charging control according to the wave charging logic. Among them, the duration T3 is the duration required for the charging amount Q1 to reach the emergency power threshold Q2, that is, the time required for the mobile phone to reach the emergency power threshold Q2 during charging, and low-power charging can still be performed after meeting the overheating risk conditions.

[0087] S44. Obtain the charging power P1 and define the charging power as d1, obtain the total power of the mobile phone battery and define it as Q3, and define the charging power in the low-power mode as d2;

[0088] S45. Calculate the charging duration T4 in the low-power mode and the duration T5 under the standard charging power based on the charging power d1, d2, the estimated power D, the total battery power Q3, the duration T3, the charging start time t0, and the charging end time t1; among them, the calculation is carried out through the formula:

[0089] d1(T3 + T5) + d2T4 = D × Q3

[0090] Among them, T4 and T5 respectively represent the charging time in the low-power mode and the charging time for switching back from the low-power mode to the high-power mode.

[0091] T3 + T4 + T5 = t1 - t0

[0092] By substituting x1 into the above formula, we can get:

[0093] d1(T3 + T5) + d2(t1 - t0 - T3 - T5) = D × Q3

[0094] Among them, d1, d2, and T3 have been set during the production of the power bank, and t1, t0, D, and Q3 have been filled in when the user obtains the power bank. Then, the charging time after switching back from the low-power mode to the high-power mode and the charging time in the low-power mode can be obtained through the above formula.

[0095] Among them, the wave charging logic includes:

[0096] Control the power bank to charge at the preset standard charging power with high power priority at time t0 and the subsequent duration T3;

[0097] Control the power bank to charge in the preset low-power mode at time t0 + T3 and the subsequent duration T4;

[0098] Control the power bank to resume charging at the preset standard power with high power priority at time t0 + T3 + T4 and the subsequent duration T5; among them, the time difference T2 = duration T3 + duration T4 + duration T5.

[0099] According to the above content, it can be seen that this method enables users to charge efficiently during the charging process and reduce the heat generation during charging by reducing the charging power.

[0100] Refer to Figure 2 And Figure 3, in an embodiment of the present method, the interaction unit includes a display and function keys, and the function keys at least include a reset key, and the reset key is installed on the outer wall of the power bank in an embedded form.

[0101] Let the front and back sides of the power bank be respectively provided with guiding grooves, the guiding grooves are parallel to the length direction of the power bank and one end communicates with the installation groove / hole of the reset key. Let a pressing plate be fixed on the inner wall of the charging cavity of the corresponding charging bin of the power bank, and an arc angle is formed at the end of the side of the pressing plate facing the center of the charging cavity; wherein, the key cap of the reset key extends out of the power bank and is located in the guiding groove, and the pressing plate is installed at the bottom of the charging cavity (wherein, the pressing plate can be fixed in the charging cavity of the charging bin by bolts, and pressing plates need to be installed both above and below the charging cavity so that when the user returns the power bank and the pressing plate abuts against the reset key, it is not restricted by the front or back of the return).

[0102] Let the power bank slide in the guiding groove when inserted into the charging bin.

[0103] A signal for resetting the charging power of the power bank, which includes: the signal output after the reset key is triggered.

[0104] According to the above content, in the present method, when the user returns the power bank, the key cap is pressed by the arc angle of the pressing plate to automatically disconnect the Bluetooth connection with the current mobile phone to cooperate with the charging of the new target mobile phone.

[0105] A signal for resetting the charging power of the power bank, which includes:

[0106] Mode 1:

[0107] If currently connected to any mobile phone via Bluetooth and receives data of a new target mobile phone sent by the cloud platform, it is defined as a signal for resetting the charging power of the power bank; wherein, the new target mobile phone scans the QR code on the surface of the power bank, and the cloud platform sends the data of the new target mobile phone to the power bank.

[0113] Among them, the new Bluetooth pairing request is generated after the mobile phone scans the two-dimensional code preset on the outer wall of the power bank to obtain the Bluetooth name of the power bank and then requests pairing.

[0114] According to the above content, this method can be used by the new target mobile phone to connect to the Bluetooth of the power bank by scanning the two-dimensional code on the surface of the power bank, improving the flexibility of the Bluetooth connection between the power bank and the mobile phone.
