[0029] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0030] Considering that the mobile power supply in the existing solution has a single function and cannot fully meet the user's demand for better efficiency and greater intelligence of the mobile power supply, the present application proposes a mobile power supply control circuit and a mobile power supply device. The mobile power supply control circuit of the present application can not only use two connection ports for power transmission to improve the efficiency of the mobile power supply, but also use the interface control module to control the power management module, the first connection port and the second connection port, so that the first connection port and the second connection port are connected to form a combination cable when the mobile power supply operates in the combination mode, so that the user can use the combination cable to transmit data and / or power between two external devices. For example, when the user's computer and camera and other devices need to transmit data but there is no suitable transmission cable, the mobile power supply can be used as a data cable to connect the computer and the camera device to realize data transmission between the two devices; or, if a wearable device can only be charged with a low power by a computer or other device, the mobile power supply can be used to achieve transfer charging, which greatly improves the intelligence of the mobile power supply.

[0031] The control circuit of the mobile power supply is described below with reference to some specific embodiments.

[0032] In one embodiment, Figure 1 A structural schematic diagram of the control circuit of a mobile power supply according to an embodiment of the present application is shown. Exemplarily, the control circuit of the mobile power supply includes: a battery module 11, a power management module 12, a first connection port 13, a second connection port 14 and an interface control module 15.

[0033] Specifically, the battery module 11 may include a single battery cell, or the battery module 11 may include multiple battery cells, and the multiple battery cells are connected in series and / or in parallel to form the entire battery module 11. The battery module 11 is used to transmit power to an external device through a connection port, and to provide the working power required by the control circuit of the mobile power supply.

[0034] The power management module 12 can be any mobile power management chip. Exemplarily, the power management module 12 is EDP2046.

[0035] The first connection port 13 can be a power input connection port, the first connection port 13 can also be a power output connection port, the first connection port 13 can also be a power input connection port and a power output connection port. It can be understood that the first connection port 13 can be any type of connection port, the first connection port 13 can be a USB Type-A interface, the first connection port 13 can also be a USB Type-C interface, the first connection port 13 can also be a Micro USB interface, the first connection port 13 can also be a Lightning interface, etc. The first connection port 13 can be set according to actual application conditions.

[0037] The power management module 12 is electrically connected to the first connection port 13 and the second connection port 14 respectively. The interface control module 15 is electrically connected to the power management module 12 , the first connection port 13 and the second connection port 14 respectively.

[0038] Any controller can be set in the interface control mode. An MCU can be set in the interface control module 15 and controlled by the MCU; a CPU can be set in the interface control module 15 and controlled by the CPU; a DSP can be set in the interface control module 15 and controlled by the DSP; an FPGA can be set in the interface control module 15 and controlled by the FPGA.

[0039] The interface control module 15 is used to control the power management module 12 to prohibit power transmission between the battery module 11 and the first connection port 13 and / or the second connection port 14 when the mobile power supply is operating in the combination mode, and to connect the first connection port 13 and the second connection port 14 to achieve data transmission and / or power transmission between the first external device connected to the first connection port and the second external device connected to the second connection port.

[0040] Power transfer refers to the transfer of power from a first external device to a second external device, or from a second external device to a first external device.

[0041] The interface control module 15 can control the conduction between the first connection port 13 and the second connection port 14 through a switch element.

[0042] The operating mode of the mobile power supply can be directly controlled by the controller in the interface control module 15; a control element can also be set in the interface control module 15 to control the operating mode of the mobile power supply; or a special control element can be set to be electrically and / or communicatively connected to the interface control module 15, and the operating mode of the mobile power supply can be controlled by the special control element.

[0043] According to the structure of the specific connection port, the pins to be connected to the first connection port 13 and the second connection port 14 can be controlled so that the first connection port 13 and the second connection port 14 form a combination cable. It can be understood that the input port and output port of the combination cable can be set according to the actual application situation. The input port of the combination cable can be set to the first connection port 13, and the output port of the combination cable can be set to the second connection port 14; the input port of the combination cable can also be set to the second connection port 14, and the output port of the combination cable can be set to the first connection port 13.

[0044] The transmission of the combined cable can be set according to the actual application situation. The power pins of the first connection port 13 and the second connection port 14 can be connected, and power transmission can be performed using the combined cable. The data transmission pins of the first connection port 13 and the second connection port 14 can also be connected, and data transmission can be performed using the combined cable. The data transmission pins and power pins of the first connection port 13 and the second connection port 14 can also be connected at the same time, and data transmission and power transmission can be performed simultaneously using the combined cable.

[0045] The control circuit of the mobile power supply of this embodiment is provided with two connection ports, which are used for power transmission. An interface control mode is also provided. When the mobile power supply operates in a combination mode, the first connection port 13 and the second connection port 14 are connected, so that the first connection port 13 and the second connection port 14 are used as a combination cable for transmission, which greatly improves the intelligence of the mobile power supply.

[0046] In one embodiment, based on the above embodiment, the interface control module 15 is further used to disconnect the first connection port 13 and the second connection port 14 when the mobile power supply operates in independent mode, and to allow the battery module 11 to transmit power to the first connection port 13 and / or the second connection port 14 by controlling the power management module 12, so that the first connection port 13 and the second connection port 14 respectively act as independent cables for power transmission.

[0047] It is understandable that the first connection port 13 and the second connection port 14 are used as independent cables for power transmission, which can be used to charge the battery module 11 or the battery module 11 can be used to charge an external device.

[0048] When the mobile power supply operates in independent mode, the relevant pins of the first connection port 13 and the second connection port 14 are controlled to be disconnected, so that the first connection port 13 and the second connection port 14 are used as independent cables for charging or discharging. The transmission between the battery module 11 and the first connection port 13 and the second connection port 14 can be set according to actual application conditions. The battery module 11 can only transmit power to the first connection port 13, the battery module 11 can also only transmit power to the second connection port 14, or the battery module 11 can also transmit power to the first connection port 13 and the second connection port 14.

[0049] In the control circuit of the mobile power supply of this embodiment, when the mobile power supply is in standalone mode, the first connection port 13 and the second connection port 14 can independently perform input and output, and perform parallel charging, thereby improving efficiency, while also increasing the flexibility and reliability of the mobile power supply to meet the needs of different devices.

The mode control module 16 can also be a dip switch, which is used to control the working mode of the mobile power supply. The mode control module 16 can also be a knob switch, which can be used to control the working mode of the mobile power supply. Exemplarily, the mode control module 16 is a button. Further, the mode control module 16 can also be voice controlled or induction controlled.

[0053] The control circuit of the mobile power supply of this embodiment is provided with a mode control module 16 to switch the working mode of the mobile power supply, which greatly improves the flexibility and reliability of the system.

[0059] Specifically, the status indicator module 18 can be a light indicator, a digital indicator, or an audible indicator. The status indicator method and content can be set according to the actual application. For example, a single LED light is used to indicate the working status of the mobile power supply, and four LED lights are used to indicate the power level of the mobile power supply.

[0060] The control circuit of the mobile power supply of this embodiment is provided with a status indication module 18 to indicate the working status and power level of the mobile power supply, so that the user can more intuitively understand the working status and power level of the mobile power supply, thereby better managing the use of the device, greatly improving the user experience, and ensuring the safety and reliability of the mobile power supply.

[0061] In one embodiment, if Figure 2 As shown, based on the above embodiment, the control circuit of the mobile power supply further includes: a charging connector 19 , which is electrically connected to the battery module 11 and the power management module 12 respectively.

[0062] Specifically, the first connection port 13 and the second connection port 14 of this embodiment are discharge connection ports, which are used to charge external devices using the battery module 11, and the charging connection port 19 uses an external device to charge the battery module 11. It can be understood that the charging connection port 19 can be any type of connection port. The charging connection port 19 can be a USB Type-A interface, the charging connection port 19 can also be a USB Type-C interface, the charging connection port 19 can also be a Micro USB interface, the charging connection port 19 can also be a Lighting interface, etc.

[0063] The control circuit of the mobile power supply of this embodiment is provided with a dedicated charging connector 19 for charging the mobile power supply, which can clearly define the division of labor and reduce the possibility of user misoperation. The dedicated charging connector 19 can better support specific charging protocols and achieve fast charging. The separation of the input port and the output port can better isolate the input and output of the power supply, reduce the risk of chain reactions caused by faults, and improve the safety and reliability of the mobile power supply.

[0066] The control unit 151 can be any type of controller, and the first interface switching unit 152 and the second interface switching unit 153 are used to connect different pins of the first connection port 13 and the second connection port 14. If the first interface switching unit 152 connects the first data transmission pin of the first connection port 13 and the second connection port 14, then the second interface switching unit 153 connects the second data transmission pin of the first connection port 13 and the second connection port 14. It can be understood that if the first connection port 13 and the second connection port 14 are set to any number of data pins greater than 2, an interface switching unit corresponding to the number of data pins can be set to control each data pin.

[0067] Any type of switching element can be set in the first interface switching unit 152. A switching tube can be set in the first interface switching unit 152 for control.
