[0045] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0046] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0047] Figure 1 This is a flow chart of a method for controlling the output of a mobile power supply according to an embodiment of the present invention. Specifically, the mobile power supply includes a controller and at least two output ports. The output voltages of the output ports include a low voltage range and a high voltage range. The at least two output ports include a first output port C1 and a second output port C2. Optionally, the output ports are Type-C ports.

[0048] This embodiment is applicable to the situation where two charging devices are fast charged at the same time. The method can be executed by the output control device of the mobile power supply. The output control device of the mobile power supply can be implemented in the form of hardware and / or software. The output control device of the mobile power supply can be configured in the controller of the mobile power supply.

[0049] like Figure 1 As shown, the output control method of the mobile power supply includes:

[0050] S110 , controlling the first output port C1 to execute a fast charging mode to charge the first charging device.

[0051] The output port that is connected to the charging device first is the first output port C1, and the output port that is connected to the charging device later is the second output port C2. For example, if a mobile power supply has two output ports, one on the left and one on the right, if the output port on the left is connected to the charging device first, the output port on the left is the first output port C1, and the output port on the right is the second output port C2. If the output port on the right is connected to the charging device first, the output port on the right is the first output port C1, and the output port on the left is the second output port C2.

[0052] In fast charging mode, the output voltage of the first output port C1 or the second output port C2 is a high voltage, and the specific output voltage has different high voltage gears, for example, 9V, 12V, 15V or 20V. Specifically, the controller will synchronously send two protocol packets (PD packets) to the first output port C1, one is a low voltage gear (for example, 5V) protocol packet, and the other is a high voltage gear protocol packet (i.e., fast charging voltage packet). The first output port C1 executes the fast charging mode after determining that it has received the high voltage gear protocol packet.

[0053] S120 , detecting whether the second output port C2 is connected to a second charging device; if so, executing S130 ; otherwise, continuing to execute S120 .

[0054] S130 , recording the output voltage level of the first output port C1 .

[0055] In the fast charge mode, the first output port C1 outputs a high voltage gear, and the high voltage gear has at least two voltage levels, for example, 9V, 12V, 15V, or 20V.

[0056] S140 , negotiate with the first output port C1 to output a low voltage gear.

[0057] The low voltage gear is the default voltage gear. If the negotiation fails, the first output port C1 receives the low voltage gear protocol packet by default. Even if the second output port C2 receives the high voltage gear protocol packet, it cannot output the high voltage gear voltage.

[0058] S150 , determine whether the negotiation is successful; if so, execute S160 ; otherwise, execute S1A0 .

[0059] S160: Establish a fast charging protocol connection with the second output port C2.

[0060] If the negotiation is successful, the first output port C1 will output the low voltage gear, but the process of the controller establishing a connection with the second output port C2 and receiving the high voltage gear protocol packet is relatively short. Therefore, although the low voltage gear protocol packet is communicated in this step, the first output port C1 does not output the low voltage gear.

[0061] S170 , determining whether the requested voltage of the second output port C2 is equal to the voltage recorded at the first output port C1 ; if so, executing S180 ; otherwise, executing S1A0 .

[0062] S180: Whether the second output port C2 and the first output port C1 negotiate to output the same voltage level; if so, execute S190; otherwise, execute S1A0.

[0063] S190 , the second output port C2 and the first output port C1 start the dual-port fast charging mode.

[0064] S1A0, the first output port C1 and the second output port C2 are in a shared low voltage charging mode.

[0065] When the embodiment of the present invention detects that a device is connected to the second output port C2 for charging, it records the output voltage level of the first output port C1 and negotiates with the first output port C1 to output a low voltage level. After the negotiation is successful, it establishes a fast charging protocol connection with the second output port C2. When the requested voltage of the second output port C2 is equal to the voltage recorded by the first output port C1 and the second output port C2 and the first output port C1 negotiate to output the same voltage level, the second output port C2 and the first output port C1 start the dual-port fast charging mode. It can be seen that the embodiment of the present invention realizes the dual-port output of high voltage of the mobile power product at the same time, thereby meeting the fast charging needs of multiple devices, improving work efficiency, and helping users to travel with full charge anytime and anywhere.

[0066] For a simpler description, the first output port C1 is referred to as port C1, and the second output port C2 is referred to as port C2. Furthermore, illustratively, the low voltage gear is 5V, the low voltage gear charging mode is the 5V charging mode, and the shared low voltage gear charging mode is the shared 5V charging mode.

[0067] Based on the above embodiments, optionally, before S110, controlling the first output port to execute the fast charging mode to charge the first charging device, the following steps are further included:

[0068] Detecting the connection status of the first output port C1 and the second output port C2;

[0069] After detecting that the first output port C1 is connected to the first charging device, establishing a fast charging protocol connection with the first output port C1;

[0070] If the protocol connection is successful, the first output port C1 executes the fast charging mode; otherwise, it executes the low voltage gear charging mode.

[0071] This arrangement can realize both dual-port output of the mobile power supply and single-port output of the mobile power supply.

[0072] Based on the above embodiments, optionally, after S190, the second output port C2 and the first output port C1 start the dual-port fast charging mode, the following steps are further included:

[0073] If the first output port C1 requests a new voltage or the second output port C2 requests a new voltage, the first output port C1 and the second output port C2 negotiate to output the same voltage level;

[0074] If the negotiation is successful, the system returns to the dual-port fast charging mode; otherwise, the system executes the shared low-voltage charging mode.

[0075] This setting realizes the switching of dual-port fast charging voltage, which is conducive to being applicable to a wider range of application scenarios.

[0076] Specifically, Figure 2 This is a flow chart of another output control method of a mobile power supply provided by an embodiment of the present invention. Figure 2 , exemplarily, the low voltage gear is 5V. The output control method includes the following steps:

[0077] S210 , detecting whether the C1 port is connected to a charging device; if so, executing S220 ; otherwise, continuing to execute S210 .

[0078] S220: Establish a fast charging protocol connection with port C1.

[0079] S230: Execute single C1 port fast charging mode.

[0080] S240 , detecting whether the C2 port is connected to a charging device; if so, executing S250 ; otherwise, continuing to execute S230 .

[0081] S250. Record the voltage level of port C1.

[0082] S260: Negotiate that port C1 outputs 5V voltage.

[0083] S270, determine whether the C1 port successfully negotiates 5V; if so, execute S280; otherwise, execute S2E0.

[0084] If the connection is unsuccessful, the C1 port will default to receiving 5V protocol packets. Even if the C2 port is successful, it will only receive 5V protocol packets, thus implementing the shared 5V charging mode. If the connection is successful, the C1 port will theoretically output 5V. However, considering that the C1 port will receive high-voltage protocol packets in a shorter time after the C2 port is connected, the C1 port can be defaulted to communicating 5V but not outputting 5V.

[0085] S280 and C2 ports establish a fast charging protocol connection.

[0086] S290 , determine whether the requested voltage of port C2 is equal to the voltage level recorded at port C1 ; if so, execute S2A0 ; otherwise, execute S2E0 .

[0087] S2A0: Check whether the two ports have successfully negotiated to output the same voltage. If so, execute S2B0; otherwise, execute S2E0.

[0088] S2B0, turn on dual-port fast charging mode.

[0089] S2C0: Determine whether any port requests a new voltage; if so, execute S2D0; otherwise, return to execute S2B0.

[0090] S2D0: Check whether the two ports have successfully negotiated to output the same voltage. If so, the process returns to S2B0; otherwise, the process proceeds to S2E0.

[0091] S2E0, turn on shared 5V charging mode.

[0092] The embodiment of the present invention can charge the device using only the C1 port, realizing the single-port output of the mobile power supply. The embodiment of the present invention can also start the dual-port fast charging mode after detecting that a device is connected to the C2 port by recording the output voltage gear of the C1 port, negotiating with the C1 port to output 5V, and establishing a fast charging protocol connection with the C2 port after the negotiation is successful. It can be seen that the embodiment of the present invention realizes the simultaneous output of high voltage from the two ports of the mobile power product, thereby meeting the fast charging needs of multiple devices, improving work efficiency, and helping users to travel with full power anytime, anywhere. In addition, after turning on the dual-port fast charging mode, the dual-port fast charging voltage can also be switched, which is conducive to being applicable to a wider range of application scenarios.

[0093] Based on the above embodiments, optionally, the C1 port can also execute a single C1 port low voltage gear charging mode. After executing the low voltage gear charging mode, the method further includes:

[0094] Check the connection status of the C2 port;

[0095] If it is detected that the C2 port is connected to a second charging device, the C1 port and the C2 port are in a shared low-voltage charging mode.

[0096] With this setting, even if the C2 port requests a high voltage output, it will not succeed, ensuring the safety of mobile power charging.

[0097] Based on the above embodiments, optionally, when the shared low voltage charging mode of the C1 port and the C2 port is executed, the following steps are further included:

[0098] If the first charging device of the C1 port is removed, or the second charging device of the C2 port is removed, return to the step of establishing a fast charging protocol connection with the C1 port.

[0099] This arrangement can reconfirm the charging mode of the port where the charging device is not removed after a charging device is removed, which is beneficial to ensuring the safety of the mobile power supply.

[0100] Based on the above embodiments, optionally, after executing the low voltage gear charging mode, the method further includes:

[0101] Detect whether the first charging device of the C1 port is removed; if so, return to the step of detecting the connection status of the C1 port and the C2 port; otherwise, return to the step of detecting the connection status of the C2 port.

[0102] This setting can detect the connection status of each port in real time, thereby improving the timeliness of charging.

[0103] Based on the above embodiments, optionally, before determining that the C1 port executes the fast charging mode, the method further includes:

[0104] Detect whether the C2 port is connected to the second charging device. If the C2 port is not connected, the C1 port executes the fast charging mode.

[0105] This setting can avoid the safety hazards caused by turning on fast charging on the C1 port while the C2 port is connected to a charging device, further improving the safety of mobile power charging.

[0106] Based on the above embodiments, optionally, after determining that the requested voltage of the C2 port is equal to the voltage recorded at the C1 port, the method further includes:

[0107] Re-establish the fast charge protocol connection with the C1 port and determine whether the requested voltage of the C1 port is equal to the requested voltage of the C2 port;

[0108] If so, the dual-port fast charging mode is executed; otherwise, the shared low-voltage gear charging mode is executed.

[0109] Specifically, Figure 3This is a flow chart of another output control method of a mobile power supply provided by an embodiment of the present invention. Figure 3 , exemplarily, the low voltage gear is 5V. The output control method includes the following steps:

[0110] S310, detect whether any port is connected to a charging device; if so, the port is the C1 port, and the port not connected to the charging device is the C2 port; execute S320; otherwise, return to execute S310.

[0111] S320. Establish a protocol connection with port C1.

[0112] S330. Determine whether the protocol connection is successful; if so, execute S390; otherwise, execute S340.

[0113] S340 , detecting whether the C2 port is connected to a charging device; if so, executing S350 ; otherwise, executing S370 .

[0114] S350, C1 port and C2 port are in shared 5V charging mode.

[0115] S360: Is any charging device removed from any port? If so, the port from which the device has not been removed is port C1, and the process returns to S320; otherwise, the process continues to S350.

[0116] The S370 and C1 ports are in normal 5V charging mode.

[0117] S380: Is the charging device at port C1 removed? If so, return to S310; otherwise, continue to S340.

[0118] S390 , detecting whether the C2 port is connected to a charging device; if so, executing S3C0 ; otherwise, executing S3A0 .

[0119] The S3A0 and C1 ports are in fast charging mode.

[0120] S3B0, check whether the charging device at port C1 is removed; if so, return to S310; otherwise, continue to S390.

[0121] S3C0, record the voltage level of port C1.

[0122] S3D0 negotiates 5V voltage with C1 port.

[0123] S3E0: Determine whether the 5V voltage negotiation is successful; if so, execute S3F0; otherwise, execute S3P0.

[0124] S3F0 establishes a protocol connection with port C2.

[0125] S3G0 checks whether the protocol connection with port C2 is successful; if so, execute S3H0; otherwise, execute S3P0.

[0126] S3H0. Get the voltage level requested by port C2.

[0127] Check whether the voltage requested by S3I0 and C2 ports is equal to the voltage level recorded by C1 port; if so, execute S3J0; otherwise, execute S3P0.

[0128] S3J0 re-establishes the protocol connection with port C1.

[0129] Check whether the voltage requested by S3K0 and C1 ports is equal to the voltage requested by C2 port; if so, execute S3L0; otherwise, execute S3P0.

[0130] S3L0: Detect whether any port has a new requested voltage; if so, execute S3O0; otherwise, execute S3M0.

[0131] S3M0, C1 port and C2 port enable dual-port fast charging mode.

[0132] S3N0. Determine whether any device has been removed from any port; if so, the port from which the device has not been removed is port C1, and return to execute S320; otherwise, continue to execute S3L0.

[0133] S3O0: Check whether the voltage of the other port is negotiated successfully. If so, execute S3M0; otherwise, execute S3P0.

[0134] S3P0, C1 port and C2 port start shared 5V charging mode.

[0135] S3Q0. Determine whether a charging device has been removed from any port; if so, the port from which the device has not been removed is port C1, and return to execute S320; otherwise, continue to execute S3P0.

[0136] The embodiment of the present invention can charge the device using only the C1 port, realizing the single-port output of the mobile power supply. The embodiment of the present invention can also start the dual-port fast charging mode after detecting that a device is connected to the C2 port by recording the output voltage gear of the C1 port, negotiating with the C1 port to output 5V, and establishing a fast charging protocol connection with the C2 port after the negotiation is successful. It can be seen that the embodiment of the present invention realizes the simultaneous output of high voltage from the two ports of the mobile power product, thereby meeting the fast charging needs of multiple devices, improving work efficiency, and helping users to travel with full power anytime, anywhere. In addition, after turning on the dual-port fast charging mode, the dual-port fast charging voltage can also be switched, which is conducive to being applicable to a wider range of application scenarios.
