[0054] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0055] In the related art, the current carrying capacity of a cable is identified through a charging communication protocol such as the PD (Power Deliver) protocol. The embodiments of the present disclosure propose a cable that relies on hardware to identify the current carrying capacity of the cable, and a method, device and system for identifying the current carrying capacity of the cable.

[0056] Reference Figure 1 , Figure 1 is a block diagram of a cable according to an exemplary embodiment. Figure 1 As shown, the cable includes:

[0057] A signal processing module 101, wherein a voltage input terminal of the signal processing module 101 is used to connect to a power supply device 102, and an output terminal of the signal processing module 101 is used to connect to a device to be charged 103;

[0058] The signal processing module 101 is configured to process the target electrical signal into a target voltage signal according to the current carrying capacity of the cable when receiving the target electrical signal output by the power supply device 102 at the voltage input end, so that the charged device 103 can identify the current carrying capacity of the cable according to the target voltage signal.

[0059] In the embodiment of the present disclosure, when the signal processing module receives the target electrical signal output by the power supply device, the target electrical signal can be processed into a target voltage signal according to the current carrying capacity of the cable, so that the device to be charged can identify the current carrying capacity of the cable according to the target voltage signal. Thus, the current carrying capacity of the cable can be identified according to the hardware structure of the cable, rather than relying on the communication protocol to identify the current carrying capacity of the cable, thereby reducing communication time and improving communication efficiency.

[0060] In order to enable those skilled in the art to better understand the cables in the embodiments of the present disclosure, the above modules are described in detail below with examples.

[0061] For example, in the default state, the cable is disconnected from the power supply device 102 and the device to be charged 103. In the charging state, the power supply device 102 and the device to be charged 103 are connected by a cable. The voltage input terminal of the signal processing module 101 is used to connect with the power supply device 102. The power supply device 102 can provide voltage to the signal processing module 101, and the power supply device 102 can output a target electrical signal so that the signal processing module 101 processes the target electrical signal into a target voltage signal according to the current carrying capacity of the cable. Among them, the target voltage signal may include a voltage value corresponding to the current carrying capacity of the cable. After the device to be charged 103 receives the target voltage signal, the voltage value of the target voltage signal can be identified, so as to determine the current carrying capacity of the cable according to the voltage value, and realize the identification of the current carrying capacity of the cable by relying on the cable hardware. Among them, the current carrying capacity of the cable can represent the maximum current value that can pass without causing the conductor or its insulation layer in the cable to melt.

[0062] For example, before the cable and the device to be charged communicate, after the cable's current carrying capacity is identified by the cable's hardware, the cable's current carrying capacity may not be identified through the protocol layer. Therefore, the embodiments of the present disclosure can perform other communication content with the device to be charged through the cable after the cable's current carrying capacity is identified by the cable's hardware, which can reduce communication time and improve communication efficiency.

[0063] As an optional implementation, the signal processing module includes a switch module and a pull-up module, the voltage input end of the switch module is used to connect to the power supply device, the output end of the switch module is connected to the input end of the pull-up module, and the output end of the pull-up module is used to connect to the device to be charged;

[0064] The switch module is configured to conduct the power supply device and the pull-up module when the voltage input terminal receives the initial electrical signal output by the power supply device, so that the pull-up module receives the target electrical signal;

[0065] The pull-up module is configured to process the target electrical signal into a target voltage signal according to the current carrying capacity of the cable, so that the device to be charged can identify the current carrying capacity of the cable according to the target voltage signal.

[0066] For example, the voltage input terminal of the switch module can be connected to the power supply device, and the power supply device sends an initial electrical signal to the switch module, providing voltage to the switch module to conduct the power supply device and the pull-up module. The input target electrical signal is sent to the pull-up module, and the pull-up module can process the target electrical signal into a target voltage signal according to the current carrying capacity of the cable.

[0067] For example, the voltage values ​​of the initial electrical signal and the target electrical signal may be equal or unequal. The initial electrical signal is used to provide a voltage value for turning on the switch module, so the initial electrical signal may be greater than the voltage value for starting the switch module. The target electrical signal is used to input the pull-up module, and the pull-up module may pull up the voltage value of the target electrical signal to a voltage value corresponding to the current carrying capacity of the cable, so the voltage value of the target voltage signal may be greater than the voltage value of the target electrical signal.

[0068] For example, the switch module controls the switch module to turn on through the voltage value of the initial electrical signal output by the power supply device. The switch module can use components such as transistors, field effect transistors, and relays.

[0069] In one optional implementation, the switch module is a transistor, the base and collector of the transistor are used as voltage input terminals for connecting to a power supply device, and the emitter of the transistor is connected to the input terminal of the pull-up module.

[0070] In another optional implementation, the switch module is a relay, both ends of the relay coil are used as voltage input ends for connecting to the power supply device, one end of the relay armature is used for connecting to the power supply device, and the other end of the relay armature is connected to the input end of the pull-up module.

[0071] As an optional implementation, the voltage input end of the signal processing module includes a first voltage input end and a second voltage input end, the second voltage input end is used to connect to the power supply device, and the cable also includes:

[0072] A delay module, wherein the input end of the delay module is used to connect to the power supply device, and the output end of the delay module is connected to the first voltage input end. The delay module is configured to delay the initial electrical signal when receiving the initial electrical signal output by the power supply device, and send the initial electrical signal to the first voltage input end so that the signal processing module receives the target electrical signal.

[0073] For example, the delay module is used to delay the signal input into the first voltage input terminal of the power supply device and obtain the initial electrical signal from the communication bus. The initial electrical signal can be used by the signal processing module to input the target electrical signal of the power supply device into the second voltage input terminal. The signal processing module can process the target electrical signal into a target voltage signal according to the current carrying capacity of the cable.

[0074] As an optional implementation, the signal processing module includes a switch module and a pull-up module, the voltage input end of the switch module is used to connect to the power supply device, the output end of the switch module is connected to the input end of the pull-up module, the output end of the pull-up module is used to connect to the device to be charged, and the voltage input end of the switch module includes a first voltage input end and a second voltage input end;

[0075] The switch module is further configured to conduct the power supply device and the pull-up module when the first voltage input terminal receives the initial electrical signal, so that the pull-up module receives the target electrical signal;

[0076] The pull-up module is configured to process the target electrical signal into a target voltage signal according to the current carrying capacity of the cable, so that the device to be charged can identify the current carrying capacity of the cable according to the target voltage signal.

[0077] For example, the first voltage input terminal of the signal processing module may be the first voltage input terminal of the switch module, and the second voltage input terminal of the signal processing module may be the second voltage input terminal of the switch module. The delay module is used to delay the signal input from the power supply device to the first voltage input terminal of the switch module, and take the initial electrical signal from the communication bus to turn on the switch module, so that the switch module turns on the power supply module and the pull-up module. In this way, the power supply device can input the target electrical signal through the second voltage input terminal of the switch module, the pull-up module can process the target electrical signal into a target voltage signal according to the current carrying capacity of the cable, and the device to be charged can identify the current carrying capacity of the cable according to the target voltage signal.

[0078] As an optional implementation, the cable further includes:

[0079] A first timing module, the first timing module is connected to the delay module and is configured to time a first duration of connecting the power supply device and the pull-up module;

[0080] The delay module is configured to control the switch module to disconnect the power supply device and the pull-up module when the first duration is greater than or equal to the first preset duration.

[0081] For example, the first timing module can be connected to the delay module as an external timing circuit, which is used to time the first duration of the conduction between the power supply device and the pull-up module, and start timing when the delay module takes the initial electrical signal from the communication bus to turn on the switch module. The first timing module outputs a control signal to the delay module when the first duration is greater than or equal to the first preset duration, and the delay module controls the switch module to disconnect the power supply device and the pull-up module according to the control signal. The signal processing process within the first preset duration includes that the power supply device transmits the target electrical signal to the signal processing module, and the signal processing module processes the target electrical signal into a target voltage signal.

[0082] As another optional implementation, the delay module includes:

[0083] A second timing module is configured to time a second duration of connecting the power supply device and the pull-up module;

[0084] The control module is configured to control the switch module to disconnect the power supply device and the pull-up module when the second duration is greater than or equal to a second preset duration.

[0085] For example, the timer can be integrated in the delay module. The integrated circuit has the advantages of small size, light weight, fewer lead wires and welding points, long life, high reliability, good performance, etc., while low cost and easy mass production.

[0086] For example, the second timing module can be used to time the second duration of the connection between the power supply device and the pull-up module, and start timing when the delay module takes the initial electrical signal from the communication bus to turn on the switch module. The second timing module outputs a control signal to the delay module when the second duration is greater than or equal to the second preset duration, and the delay module controls the switch module to disconnect the power supply device and the pull-up module according to the control signal. The signal processing process within the second preset duration includes that the power supply device transmits the target electrical signal to the signal processing module, and the signal processing module processes the target electrical signal into a target voltage signal and sends it to the device to be charged.

[0087] As an optional implementation, the switch module is a transistor, the base of the transistor is connected to the output end of the delay module, the collector of the transistor is connected to the power supply device, and the emitter of the transistor is connected to the input end of the pull-up module.

[0088] For example, the switch module controls the switch module to turn on through the voltage value of the initial electrical signal output by the power supply device. The switch module can use components such as transistors, field effect transistors, and relays.

[0089] In another optional implementation, the switch module is a relay, the two ends of the relay coil are used as voltage input ends for connecting to the output end of the delay module, one end of the relay armature is used to connect to the power supply equipment, and the other end of the relay armature is connected to the input end of the pull-up module.

[0090] As an optional implementation, the signal processing module further includes:

[0091] The signal sending module is configured to send a target voltage signal to the device to be charged, so that the device to be charged can identify the current carrying capacity of the cable according to the target voltage signal.

[0092] For example, the target voltage signal can be sent to the device to be charged through the signal sending module of the cable. In one embodiment of the present disclosure, the device to be charged can also actively detect or identify the target voltage signal in the cable, so that the device to be charged can identify the current carrying capacity of the cable according to the target voltage signal.

[0093] See also Figure 2 A schematic diagram of the structure of a cable is provided, such as Figure 2 As shown, the cable includes a signal processing module 101, wherein the signal processing module 101 includes:

[0094] A delay module, the input end of the delay module is used to connect with the power supply device 102;

[0095] Transistor Q1, the base of the transistor is connected to the output end of the delay module, and the collector of the transistor is connected to the power supply device 102;

[0096] A pull-up module, wherein the input end of the pull-up module is connected to the emitter of the transistor, and the output end of the pull-up module is connected to the input end of the device to be charged 103 .

[0097] For example, Figure 2 The timer shown is the first timing module mentioned above, and the timer can also be set inside the delay module as a second timing module. The output end of the power supply device 102 is provided with a first resistor Rp, and the input end of the device to be charged 103 is provided with a second resistor Rd, and the end of the second resistor Rd away from the power supply device 102 is connected to the ground terminal GND.

[0098] Figure 3 is a flow chart showing a method for identifying the current carrying capacity of a cable according to an exemplary embodiment. Figure 3 As shown, the method for identifying the current carrying capacity of a cable is used in a cable, and includes the following steps.

[0099] S301. When it is determined that the power supply device and the device to be charged are connected via a cable, a target electrical signal output by the power supply device is processed into a target voltage signal according to the current carrying capacity of the cable, so that the device to be charged can identify the current carrying capacity of the cable according to the target voltage signal.

[0100] Specifically, when it is determined that the power supply device and the device to be charged are connected via a cable, for example, when the voltage input end of the cable receives a target electrical signal, the cable can process the target electrical signal output by the power supply device into a target voltage signal. The device to be charged identifies the current carrying capacity of the cable based on the target voltage signal.

[0101] In the embodiment of the present disclosure, when it is determined that the power supply device and the device to be charged are connected via a cable, the cable processes the target electrical signal into a target voltage signal according to the current-carrying capacity of the cable, so that the device to be charged can identify the current-carrying capacity of the cable according to the target voltage signal. Thus, the device to be charged can identify the current-carrying capacity of the cable through the target voltage signal of the cable, rather than relying on the communication protocol to identify the current-carrying capacity of the cable, thereby reducing communication time and improving communication efficiency.

[0102] Figure 4 is a flow chart showing a method for identifying the current carrying capacity of a cable according to an exemplary embodiment. Figure 4 As shown, the method for identifying the current carrying capacity of a cable is used in a device to be charged, and includes the following steps.

[0103] S401, obtaining a target voltage signal, where the target voltage signal is obtained by the cable according to the following steps:

[0104] When it is determined that the power supply device and the device to be charged are connected via a cable, the target electrical signal output by the power supply device is processed into a target voltage signal according to the current carrying capacity of the cable.

[0105] S402: Identify the current carrying capacity of the cable according to the target voltage signal.

[0106] For example, after the cable processes the target electrical signal into a target voltage signal, the target voltage signal can be sent to the device to be charged through the cable, or the device to be charged can actively detect or identify the target voltage signal of the cable, so that the device to be charged can determine the current carrying capacity of the cable based on the voltage value in the target voltage signal.

[0107] For example, see Figure 2 and Figure 5In the initial state, transistor Q1 is disconnected. When it is determined that the device to be charged 103 and the power supply device 102 are connected, the delay module in the signal processing module 101 delays the electrical signal output by the power supply device 102 for a period of time T, and takes voltage from the communication bus to turn on transistor Q1. Transistor Q1 conducts the power supply device and the pull-up module, and the timer starts at the same time. The pull-up module pulls up the voltage VCC received by the collector end of transistor Q1 to the voltage value in the target voltage signal. The device to be charged 103 can judge the current carrying capacity of the cable according to the voltage value of the target voltage signal. After the timer T ends, transistor Q1 is disconnected, the timer is reset, and the signal processing module 101 of the cable is set to the initial state. After detecting detach, attach again, that is, the device to be charged 103 and the power supply device 102 are disconnected and then connected again, and the signal processing module 101 works again.
