[0049] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0050] In an exemplary embodiment, Figure 1 As shown, a data line 01 is provided, which includes a first fast charging communication module 1, a second fast charging communication module 2 and a charge and discharge management module 3.

[0051] In the embodiment of the present application, the charge and discharge management module 3 is connected to the first fast charge communication module 1 and the second fast charge communication module 2 respectively;

[0052] The first fast charging communication module 1 is used to interact with the adapter 4. The process of the first fast charging communication module 1 interacting with the adapter 4 may include: the adapter broadcasts the fast charging power it supports, the first fast charging communication module in the data line receives the signal and then feeds back the fast charging power required by the adapter, and the adapter outputs the corresponding fast charging power according to the signal fed back by the first fast charging communication module in the data line.

[0053] The second fast charging communication module 2 is used to interact with the electronic device 5. The process of the first fast charging communication module 1 interacting with the adapter 4 may include: the second fast charging communication module 2 broadcasts the fast charging power output by itself, and the electronic device 5 feeds back the fast charging power required by itself to the second fast charging communication module 2 after receiving the signal, and the second fast charging communication module 2 outputs the corresponding fast charging power according to the signal fed back by the electronic device 5.

[0054] The charge and discharge management module 3 is used to interact with the first fast charge communication module 1 and the second fast charge communication module 2 respectively, and perform protocol conversion processing when it is determined that the charging protocol types of the adapter 4 and the electronic device 5 are different, so that the charging protocol types of the adapter 4 and the electronic device 5 are the same.

[0055] The above-mentioned data line includes a first fast charging communication module, a second fast charging communication module and a charge and discharge management module; the charge and discharge management module is connected to the first fast charging communication module and the second fast charging communication module respectively; the first fast charging communication module is used to interact with the adapter; the second fast charging communication module is used to interact with the electronic device; the charge and discharge management module is used to interact with the first fast charging communication module and the second fast charging communication module respectively, and perform protocol conversion processing when it is determined that the charging protocol type of the adapter and the electronic device is different, so that the charging protocol type of the adapter and the electronic device is the same. The data line of the present application can convert the charging protocol type of the adapter and the electronic device to a consistent type when the charging protocols of the adapter and the electronic device are inconsistent, thereby realizing fast charging between different fast charging protocols.

[0056] In an exemplary embodiment, based on the above embodiment, see Figure 2 In the embodiment of the present application, the first fast charging communication module 1 includes a first fast charging protocol chip 11, and the second fast charging communication module 2 includes a second fast charging protocol chip 22; the charge and discharge management module 3 is connected to the first fast charging protocol chip 11 and the second fast charging protocol chip 22 respectively.

[0057] In the embodiment of the present application, by setting the first fast charging protocol chip and the second fast charging protocol chip, the data line can quickly identify whether the protocols of the input end and the output end are the same, thereby realizing charging management.

[0058] In an exemplary embodiment, based on the above embodiment, see Figure 3 The first fast charging communication module 1 of the embodiment of the present application includes a first fast charging protocol chip 11, the second fast charging communication module 2 includes a second fast charging protocol chip 22, the first fast charging protocol chip 11 includes a first fast charging protocol, and the second fast charging protocol chip 22 includes a second fast charging protocol; the charge and discharge management module 3 includes a protocol conversion chip 31, and the protocol conversion chip 31 is connected to the first fast charging protocol chip 11 and the second fast charging protocol chip 22 respectively.

[0059] The protocol conversion chip 31 is used to convert the first fast charging protocol of the first fast charging communication module 1 into the second fast charging protocol of the second fast charging communication module 2 when it is determined that the charging protocol types of the adapter 4 and the electronic device 5 are different.

[0060] Specifically, when the fast charging protocol types at the input and output ends of the data line are inconsistent, the protocol conversion chip in the charge and discharge management module converts the two protocols into the same type, thereby achieving fast charging between different fast charging protocols; when the fast charging protocol types at the input and output ends of the data line are consistent, there is no need to convert the fast charging protocol type through the protocol conversion chip, and fast charging of electronic devices can also be achieved.

[0061] In an embodiment of the present application, when the fast charging protocol types of the data line input and output ends are inconsistent, the protocol conversion chip in the charge and discharge management module converts the two protocols into the same type, thereby achieving fast charging between different fast charging protocols; when the fast charging protocol types of the data line input and output ends are consistent, there is no need to convert the fast charging protocol type through the protocol conversion chip in the power dynamic allocation module, and fast charging of electronic devices can also be achieved.

[0062] In an exemplary embodiment, based on the above embodiment, see Figure 4 , the charge and discharge management module 3 of the embodiment of the present application further includes a dynamic power allocation module 32; the dynamic power allocation module 32 is respectively connected to the protocol conversion chip 31 and the second fast charging protocol chip 22 of the second fast charging communication module 2;

[0063] The dynamic power allocation module 32 is used to allocate the entire output power of the data line 01 to the electronic device 5 when it is determined that the maximum output power of the data line 01 matches the charging power of the electronic device 5 .

[0064] Specifically, Figure 5 As shown, if the electronic device is the first electronic device connected, when the data line recognizes that the first electronic device is connected, it is determined whether the charging power of the first electronic device reaches the maximum power supported by the data line (the charging power of the first electronic device refers to the power required by the first electronic device, and the maximum power supported by the data line refers to the maximum power that the product can output). If the charging power of the first electronic device reaches the maximum power supported by the data line, the full power output of the first electronic device is guaranteed.

[0065] If the charging power of the first electronic device does not reach the maximum power supported by the data line, determine whether a second electronic device is connected, and if a second electronic device is connected, allocate the remaining power to the second electronic device;

[0066] If a third electronic device is connected, the remaining power of the second electronic device is allocated to the third electronic device;

[0067] If there is no second electronic device or third electronic device, the full power output of the first electronic device is guaranteed.

[0068] Furthermore, the embodiment of the present application can also detect whether the device power changes during the charging process of the first electronic device when the power is output to the first electronic device. If it changes, the power distribution is dynamically adjusted according to the real-time power demand of the first electronic device until the charging is completed. If the second electronic device is connected, detect whether the device power changes during the charging process of the first electronic device and the second electronic device. If it changes, the power distribution is dynamically adjusted according to the real-time power demand of the first electronic device and the second electronic device until the charging is completed. For example, if the charging power of the first electronic device decreases, more power can be allocated to the second electronic device at this time; if the third electronic device is connected, it can also detect whether the device power changes during the charging process of the first electronic device, the second electronic device and the third electronic device when the power is output to the first electronic device, the second electronic device and the third electronic device. If it changes, the power distribution is dynamically adjusted according to the real-time power demand of the first electronic device, the second electronic device and the third electronic device until the charging is completed. For example, if the charging power of the first electronic device or the second electronic device decreases, more power can be allocated to the third electronic device at this time.

[0069] The embodiment of the present application can ensure that all charging power is output to the electronic device by determining whether the maximum output power matches the charging power of the electronic device.

[0070] In an exemplary embodiment, based on the above embodiment, see Figure 6 The data cable 01 of the embodiment of the present application also includes a third fast charging communication module 6.

[0071] Among them, the dynamic power allocation module 32 is connected to the protocol conversion chip 31, the second fast charging communication module 2 and the third fast charging communication module 6 respectively.

[0072] The second fast charging communication module 2 is used to interact with the first electronic device 7. Specifically, the second fast charging communication module broadcasts the fast charging power it outputs, and the protocol chip in the first electronic device receives the signal and feeds back the fast charging power it needs to the second fast charging communication module. The second fast charging communication module outputs the corresponding fast charging power according to the signal fed back by the first electronic device.

[0073] The third fast charging communication module 6 is used to interact with the second electronic device 8; specifically, the third fast charging communication module broadcasts the fast charging power it outputs, and the protocol chip in the second electronic device receives the signal and feeds back the fast charging power it needs to the third fast charging communication module. The third fast charging communication module outputs the corresponding fast charging power according to the signal fed back by the second electronic device.

[0074] The dynamic power allocation module 32 is used to obtain the first remaining output power according to the maximum output power and the actual charging power when the actual charging power of the first electronic device 7 does not reach the maximum output power of the data line 01, and allocate the first remaining output power to the second electronic device 8. Specifically, if the charging power of the first electronic device cannot reach the maximum power supported by the data line, the data line determines whether there is a second electronic device connected, if not, the full power output of the first electronic device is continued; if yes, the first remaining output power that the data line can provide is allocated to the second electronic device.

[0075] In the embodiment of the present application, by determining whether the maximum output power matches the charging power of the electronic device, it can be ensured that all the charging power is output to the electronic device, and when there is surplus power, while ensuring the output power of the first electronic device, the second electronic device can also meet the fast charging requirements.

[0076] In an exemplary embodiment, based on the above embodiment, see Figure 7 , the data line 01 of the embodiment of the present application further includes a fourth fast charging communication module 9, and the fourth fast charging communication module 9 is connected to the dynamic power allocation module 32;

[0077] The fourth fast charging communication module 9 is used to interact with the third electronic device 10; specifically, the fourth fast charging communication module broadcasts the fast charging power it outputs, and the protocol chip in the third electronic device receives the signal and feeds back the fast charging power it needs to the fourth fast charging communication module. The fourth fast charging communication module outputs the corresponding fast charging power according to the signal fed back by the third electronic device.

[0078] The dynamic power allocation module 32 is also used to obtain a second remaining output power based on the maximum output power and the actual charging power of the first electronic device and the second electronic device when the actual charging power of the first electronic device and the second electronic device does not reach the maximum output power of the data line, and allocate the second remaining output power to the third electronic device.

[0079] In the embodiment of the present application, by determining whether the maximum output power matches the charging power of the electronic device, it can be ensured that all the charging power is output to the electronic device, and when there is surplus power, the output power of the first electronic device and the second electronic device is guaranteed while ensuring that the surplus power is allocated to the third electronic device.

[0080] In an exemplary embodiment, the dynamic power allocation module of the embodiment of the present application is also used to obtain a first power requirement of a first electronic device during the charging process, and adjust the actual charging power of the first electronic device according to the first power requirement; and obtain a second power requirement of a second electronic device, and adjust the actual charging power of the second electronic device according to the second power requirement; and obtain a third power requirement of a third electronic device, and adjust the actual charging power of the third electronic device according to the third power requirement.

[0081] In the embodiment of the present application, during the charging process, the data line can also determine in real time whether the power demand of the device changes during the charging process. If there is a change, the power allocation is dynamically adjusted according to the real-time power demand of the electronic device. For example: as the first electronic device is charged, its required power slowly decreases, and at this time more power can be allocated to the second electronic device and the third electronic device.

[0082] The embodiment of the present application detects the actual power demand of the electronic device in real time, thereby ensuring accurate output of the charging power required by the electronic device.

[0083] In an exemplary embodiment, based on the above embodiment, the protocol conversion chip of the embodiment of the present application is also used to perform protocol conversion processing when the charging protocol type of the adapter and the second electronic device are different, so that the charging protocol type of the adapter and the second electronic device are the same. The protocol conversion chip is also used to perform protocol conversion processing when the charging protocol type of the adapter and the third electronic device are different, so that the charging protocol type of the adapter and the third electronic device are the same.

[0084] In the embodiment of the present application, Figure 8 As shown, when the data line is one-to-two data lines, a third fast charging communication module can also be provided. By analogy, when the data line is one-to-three data lines, a fourth fast charging communication module can also be provided. The functions of the third fast charging communication protocol and the fourth fast charging communication protocol are the same as those of the second fast charging communication protocol.

[0085] In an embodiment of the present application, when the fast charging protocol types of the data line input and output ends are inconsistent, the protocol conversion chip in the charge and discharge management module converts the two protocols into the same type, thereby realizing fast charging between different fast charging protocols; when the fast charging protocol types of the data line input and output ends are consistent, there is no need to convert the fast charging protocol type through the protocol conversion chip in the power dynamic allocation module, and fast charging of electronic devices can also be achieved.

[0086] The data cable of the present application can convert the charging protocol type of the adapter and the second electronic device into a consistent type when the charging protocols of the adapter and the second electronic device are inconsistent, thereby achieving fast charging between different fast charging protocols.
