[0039] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0040] Please refer to Figure 1 , Figure 1 is an application environment diagram of the method for fast charging in an embodiment. As shown in Figure 1 , the charging device 100 is used to charge the mobile terminal 200. The charging device 100 can be a charger or a power bank. The charging device 100 can have one or more connection interfaces and charge one or more mobile terminals 200 through the one or more connection interfaces. The charging device 100 supports at least one fast charging protocol. The at least one fast charging protocol includes at least one of SCP, QC, PD, PPS, FCP, PE2.0 / 1.1, AFC, and SFCP. The charging device 100 and the mobile terminal 200 can be connected through at least one way including Type-C.

[0041] Please refer to Figure 2 , Figure 2 is a flow schematic diagram of the first embodiment of the method for fast charging provided by the present application, applied to Figure 1 the charging device. The method for fast charging provided by the present application includes the following steps:

[0042] S101: When it is detected that the charging device is connected with the mobile terminal, the mobile terminal is charged in turn by using at least one fast charging protocol, and the maximum power value when each fast charging protocol is used for charging is recorded.

[0043] In one specific implementation scenario, when the charging device is detected to be connected with the mobile terminal, the mobile terminal is charged by using at least one fast charging protocol in sequence. The sequence of using the fast charging protocol can be pre-set by the manufacturer, or set according to actual use big data, and sorted according to the frequency of using the fast charging protocol by the charging device. The maximum power when each fast charging protocol is used to charge the mobile terminal is recorded. It can be that each fast charging protocol is used to charge the mobile terminal for a preset time length (for example, 5s), or the currently used fast charging protocol is switched every interval of a preset period.

[0044] For example, the charging device supports three fast charging protocols A, B and C, and charges in sequence according to the preset order ABC, for example, uses the A protocol to charge in the first 5s period, and records the maximum power value in this period. The B protocol is used to charge in the second 5s period, and the maximum power value in this period is recorded. The C protocol is used to charge in the third 5s period, and the maximum power value in this period is recorded.

[0045] S102: The maximum value of the at least one maximum power value is taken as a target power value, the fast charging protocol corresponding to the target power value is taken as a target charging protocol, and the mobile terminal is charged by using the target charging protocol.

[0046] In one specific implementation scenario, the maximum value of the maximum power value corresponding to each fast charging protocol is taken as the target power value. The fast charging protocol corresponding to the target power value is taken as the target charging protocol, for example, the charging device supports three fast charging protocols A, B and C, the maximum power value when using the A protocol is 30w, the maximum power value when using the B protocol is 35w, and the maximum power value when using the C protocol is 40w, then the target power value is 40w, and the target charging protocol is the C protocol which can provide 40w charging power. The mobile terminal is charged by using the target charging protocol. In other implementation scenarios, the maximum power values of multiple fast charging protocols can be equal in value, then one of the multiple fast charging protocols can be selected as the target charging protocol at random, or selected as the target charging protocol according to a preset selection standard (for example, the historical charging record is the most stable).

[0047] In the embodiment, the mobile terminal can be charged by the target charging protocol until the mobile terminal is fully charged or the power in the charging device is depleted (when the charging device is a power bank). In other embodiments, the user can disconnect the charging device during charging and then reconnect the mobile terminal, or the charging cable of the charging device can be accidentally disconnected. When the charging device is reconnected to the mobile terminal, steps S101-S102 can be repeated. Alternatively, when the mobile terminal is charged by at least one fast charging protocol, if the time interval between the current connection of the charging device to the mobile terminal and the previous connection of the charging device to the mobile terminal is short, the mobile terminal is first charged by the target charging protocol used in the previous charging.

[0048] As described above, in the embodiment, the mobile terminal is sequentially charged by at least one fast charging protocol, the maximum power value when the mobile terminal is charged by each fast charging protocol is obtained, the maximum value among the at least one maximum power value is taken as the target power value, the fast charging protocol corresponding to the target power value is taken as the target charging protocol, and the mobile terminal is charged by the target charging protocol. The mobile terminal can be charged by the fast charging protocol with the maximum charging power supported by the charging device, the charging efficiency is effectively improved, the charging time is saved, and the user experience is improved.

[0049] Please refer to Figure 3 , Figure 3 is a flowchart of a second embodiment of the fast charging method provided by the application, which is applied to the charging device shown in Figure 1 The fast charging method provided by the application includes the following steps:

[0050] S201: Determine whether the charging device and the mobile terminal are connected through a Type-C interface and whether the charging device is not connected to other terminals through other interfaces. If yes, perform step S202.

[0051] In a specific embodiment, when the charging device is a power bank, the charging device can have multiple connection lines, and the interfaces of the connection lines are also different (including a lightning interface, a Type-C interface, and a Micro USB interface). The charging device can also be connected to multiple mobile terminals through multiple connection lines. When the charging device and the mobile terminal are connected through a Type-C interface, one of the multiple fast charging protocols can be selected as the target charging protocol for charging.

[0052] When detecting that the detection charging device and one mobile terminal are connected, it is detected whether they are connected through a Type-C interface. If the charging device and the mobile terminal are connected through a lightning interface, the charging device charges the mobile terminal using a PD fast charging protocol. If the charging device and the mobile terminal are connected through a Type-C interface, one of multiple fast charging protocols can be selected as a target charging protocol for charging. When detecting that the detection charging device and multiple mobile terminals are connected through lightning interfaces and Type-C interfaces respectively, a Type-C_lightning hybrid output mode is used, for example, a preset rated current and / or voltage is used to charge the mobile terminals.

[0053] In another implementation scenario, when the charging device is connected to more than two mobile terminals through Type-C interfaces, a preset rated current and / or voltage can be used to charge the mobile terminals. The target charging protocol of the charging device for charging each mobile terminal can also be obtained. If the target charging protocols are the same, the target charging protocol is used to charge the multiple mobile terminals. If the target charging protocols are different, a preset rated current and / or voltage is used to charge the mobile terminals, or the maximum power value of a fast charging protocol supported by the multiple mobile terminals is obtained, and the maximum power value is used as the target charging protocol.

[0054] For example, the first mobile terminal supports three fast charging protocols A, B and D, the second mobile terminal supports three fast charging protocols B, C and D, and the charging device supports three fast charging protocols A, B and C. The fast charging protocol B is used as the target charging protocol. For another example, the first mobile terminal supports four fast charging protocols A, B, C and D, the second mobile terminal supports four fast charging protocols B, C, D and E, and the charging device supports three fast charging protocols A, B and C. The target charging protocol of the first mobile terminal is B, and the target charging protocol of the second mobile terminal is B. The fast charging protocol B is used as the target charging protocol.

[0055] S202: The mobile terminal is charged using at least one fast charging protocol in sequence. The fast charging protocol used for charging is switched every preset first period, and the maximum power value of each fast charging protocol is recorded.

[0056] In a specific implementation scenario, the charging device is connected with the mobile terminal through the Type-C interface, and is not connected with other terminals through other interfaces, and then at least one fast charging protocol is used to charge the mobile terminal in turn. In this implementation scenario, the fast charging protocol used in each charging period is switched every preset first period. The first period can be 5s. In each first period, whether the current fast charging protocol matches the mobile terminal is detected every second period. The second period can be 400ms. Detecting every second period can timely find whether the fast charging protocol matches the mobile terminal, can timely find whether the mobile terminal supports the current fast charging protocol, and can timely obtain and accurately record the maximum power value of the current fast charging protocol.

[0057] It can be understood that the fast charging protocol supported by the charging device and the fast charging protocol supported by the mobile terminal can be the same, different or partially the same. Therefore, not every fast charging protocol can be used for charging. Therefore, it is necessary to detect whether the current fast charging protocol matches the mobile terminal. When the current fast charging protocol matches the mobile terminal, the current of the fast charging protocol and / or the voltage is used to charge the mobile terminal; when the current fast charging protocol does not match the mobile terminal, the preset rated current and / or voltage is used to charge the mobile terminal.

[0058] For example, the charging device supports three fast charging protocols A, B and C, and the mobile terminal supports three fast charging protocols B, C and D. After the charging device and the mobile terminal are connected, in the first first period, the mobile terminal is charged by using the A protocol, and whether the mobile terminal matches the A protocol is detected every second period in the first period. Since the mobile terminal does not support the A protocol, the mobile terminal does not match the A protocol after a preset second period, and the mobile terminal is charged by using the preset 5V voltage, and the maximum power value a when the 5V voltage is used for charging is recorded. In the second first period, the mobile terminal is charged by using the B protocol, and whether the mobile terminal matches the B protocol is detected every second period in the first period. Since the mobile terminal supports the B protocol, the mobile terminal matches the B protocol, and the current and / or voltage corresponding to the B protocol is used to charge the mobile terminal, and the maximum power value b when the B protocol is used for charging is recorded. In the third first period, the mobile terminal is charged by using the C protocol, and whether the mobile terminal matches the C protocol is detected every second period in the first period. Since the mobile terminal supports the C protocol, the mobile terminal matches the C protocol, and the current and / or voltage corresponding to the C protocol is used to charge the mobile terminal, and the maximum power value c when the C protocol is used for charging is recorded.

[0059] Since the voltage during fast charging is greater than 5V, the values of b and c are greater than a, the maximum value among a, b and c is found, for example, the maximum value is b, and the B protocol is used as the target charging protocol for charging. If b and c are equal, one of the B protocol and the C protocol is selected as the target charging protocol for charging.

[0060] S203: The maximum value among the at least one maximum power value is taken as the target power value, the fast charging protocol corresponding to the target power value is taken as the target charging protocol, and the target charging protocol is used to charge the mobile terminal.

[0061] In a specific implementation scenario, step S203 is basically the same as step S202 in the first embodiment of the method for providing fast charging, and will not be described here.

[0062] S204: When the mobile terminal does not support all fast charging protocols, a preset rated current and / or voltage is used to charge the mobile terminal.

[0063] In a specific implementation scenario, the mobile terminal does not support all fast charging protocols, for example, the mobile terminal does not support fast charging protocols, or the fast charging protocols supported by the mobile terminal are different from the fast charging protocols supported by the charging device. A preset rated current and / or voltage is used to charge the mobile terminal, for example, a rated voltage of 5V is used for charging.

[0064] As described above, the fast charging protocol used for charging is switched every preset first period, when the current fast charging protocol matches the mobile terminal successfully, the current of the fast charging protocol and / or the voltage is used to charge the mobile terminal; when the current fast charging protocol fails to match the mobile terminal, a preset rated current and / or voltage is used to charge the mobile terminal, the maximum power value of each fast charging protocol is obtained, the maximum value among the at least one maximum power value is taken as the target power value, and the fast charging protocol corresponding to the target power value is taken as the target charging protocol. One of the fast charging protocols supported by the charging device with the maximum charging power can be selected to charge the mobile terminal, which effectively improves the charging efficiency, saves the charging time, and improves the user experience.

[0069] The recording module 11 is further configured to detect whether the current fast charging protocol matches the mobile terminal successfully every interval of a second period within the first period, and determine that the fast charging protocol fails to match the mobile terminal if the fast charging protocol is not detected to match the mobile terminal successfully for a preset number of times continuously.

[0070] The charging module 12 is further configured to use a preset rated current and / or voltage to charge the mobile terminal when the mobile terminal does not support all the fast charging protocols.

[0071] The recording module 11 is further configured to determine whether the charging device is connected with the mobile terminal through a Type-C interface and whether the charging device is not connected with other terminals through other interfaces, and perform the step of sequentially adopting at least one fast charging protocol to charge the mobile terminal and subsequent steps if the charging device is connected with the mobile terminal through the Type-C interface and is not connected with other terminals through other interfaces.

[0072] The recording module 11 is further configured to use a preset rated current and / or voltage to charge the mobile terminal if the charging device is not connected with other terminals through other interfaces, and use a PD fast charging protocol to charge the mobile terminal if the charging device is connected with the mobile terminal through a lightning interface.

[0073] As described above, in the embodiment, at least one fast charging protocol is sequentially adopted to charge the mobile terminal, the maximum power value when each fast charging protocol is used to charge is obtained, the maximum value in the at least one maximum power value is taken as a target power value, the fast charging protocol corresponding to the target power value is taken as a target charging protocol, and the target charging protocol is used to charge the mobile terminal, so that the fast charging protocol with the maximum charging power can be selected from the fast charging protocols supported by the charging device to charge the mobile terminal, the charging efficiency is effectively improved, the charging time is saved, and the user experience is improved.
