Background Art

With the development of charging technology, more and more electronic devices support fast charging.

In the related art, the current of fast charging is usually large. In order to ensure charging safety during the charging process, the charger or charging device needs to detect the overcurrent capacity of the charging cable before fast charging. For fast charging protocols with charging current greater than 3A, the E-Mark (electronically marked) chip solution is usually used to obtain the overcurrent capacity of the charging cable.

However, since the E-Mark chip can only communicate with one party (charger or charging device), the compatibility of the charging cable is poor, and the cost of using dual E-Mark chips to improve compatibility is high.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

The terms "first", "second", etc. in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and/or" in the specification and claims represents at least one of the connected objects, and the character "/" generally indicates that the objects associated with each other are in an "or" relationship.

The charging cable identification method provided in the embodiment of the present application can be applied to the scenario of charging an electronic device.

For example, in the related art, each terminal manufacturer has its own private fast charging protocol, and some fast charging protocols will increase the charging current. In order to ensure charging safety, when performing high current (usually a fast charging protocol with a charging current greater than 3A) fast charging, the charger or charging device (for example, a mobile phone, tablet, etc.) will first send an identification information acquisition request to the control module in the charging cable to obtain the maximum current load capacity of the charging cable. As shown in Figure 1, it is a charging circuit in the related art, including a charger 11, a control module 12 of a charging cable, and a charging device 13. Taking the charging cable as a TYPE-C interface as an example, the charger 11 is connected to the charging device through the D+ and D- of the TYPE-C interface, and data communication is performed through D+ and D-. And the charger 11 sends information to the charging device 13 through the D+ cable, and the charger 11 receives information sent by the charging device 13 through the D- cable. The control module 12 includes two communication ports, which are connected to the D+ and D- cables respectively. Since the data transmission directions of D+ and D- are both unidirectional, usually, the two communication ports of the E-Mark chip set on the control module, one communication port is used to receive data, and the other communication port is used to send data.

However, due to the differences in private protocols among manufacturers, some manufacturers obtain the maximum current load capacity of the charging cable from the charger, while some manufacturers obtain the maximum current load capacity of the charging cable from the charging device. After the maximum current load capacity of the charging cable meets the requirements of its fast charging protocol, the charger fast charges the charging device. As shown in (A) in Figure 1, this is a flowchart of the charger obtaining the maximum current load capacity of the charging cable, wherein the Pin1 port of the control module 12 receives the information sent by the charger 11, and then the control module 12 sends the maximum current load capacity of the charging cable to the charger 11 through the Pin2 port. As shown in (B) in Figure 1, this is a flowchart of the charging device obtaining the maximum current load capacity of the charging cable, wherein the Pin1 port of the control module 12 receives the information sent by the charging device 13, and then the control module 12 sends the maximum current load capacity of the charging cable to the charging device 13 through the Pin2 port. It can be seen that one E-Mark chip can only meet one form of fast charging protocol. If you want to be compatible with two forms of fast charging protocols, in the relevant technology, two E-Mark chips are usually set up. However, due to the high cost of E-Mark chips, in order to reduce costs, one E-Mark chip solution is usually adopted, resulting in poor compatibility of charging cables.

To address this problem, in the technical solution provided in the embodiment of the present application, in the default state of the control module, both communication ports of the E-Mark chip are in the data receiving state. When one of the Pin1 port and the Pin2 port receives the charging cable identification request, the control module switches the other communication port to the data sending state and sends the charging cable identification information through the port, so that the control module of the charging cable can receive the identification request sent from the charger or charging device through port multiplexing without adding the E-Mark chip, and send the identification information to the charger or charging device, thereby improving the compatibility of the charging cable and reducing the manufacturing cost of the charging cable. In addition, after the data transmission is completed, the control module enters the sleep mode to reduce power consumption.

The following describes in detail the charging cable identification method provided in the embodiment of the present application through specific embodiments and application scenarios in conjunction with the accompanying drawings.

As shown in FIG2 , a charging cable identification method provided in an embodiment of the present application is applied to a charging cable identification device, the device including a first communication port and a second communication port. The method may include the following steps 201 and 202:

Step 201: When the charging cable identification device is in the monitoring mode, if the first target communication port receives a charging cable identification request, the charging cable identification device switches the second target communication port from a data receiving state to a data sending state.

Exemplarily, the above-mentioned charging cable identification device may be an E-Mark chip arranged in the charging cable, or an integrated circuit equipped with the chip. The E-Mark chip includes two communication ports. Different from the related art, one of the two communication ports in the E-Mark chip is used to receive data and the other is used to send data. The charging cable identification method in the embodiment of the present application performs port multiplexing on the two communication ports of the E-Mark chip, so that it can change the data transmission status of the above-mentioned two communication ports according to actual needs.

Step 202: The charging cable identification device sends charging cable identification information through the second target communication port.

The first target communication port is one of the first communication port and the second communication port. The second target communication port is one of the first communication port and the second communication port, and the second target communication port is different from the first target communication port. In the monitoring mode, the first communication port and the second communication port are both in a data receiving state.

Exemplarily, when a user uses a charging cable including the above-mentioned charging cable identification device to charge, in order to prevent the charging current from exceeding the maximum carrying capacity of the charging cable and causing safety hazards, before charging, the charger or charging device needs to send a charging cable identification request to the charging cable identification device, and the request is used to obtain the current carrying capacity of the charging cable. Since the charging cable identification device does not know whether the request is sent by the charger or the charging device before receiving the request, both communication ports of the charging cable identification device can be set to a data receiving state. After receiving the request, the charging cable identification device switches the data transmission state of the other communication port (i.e., the above-mentioned second target communication port) of the above-mentioned two communication ports except the first target communication port that receives the request from the data receiving state to the data sending state. Afterwards, the charging cable identification device sends the charging cable identification information to the charger or charging device through the second target communication port.

It should be noted that the above charging cable identification request can also be used to obtain the maximum withstand voltage information of the charging cable and the cable impedance information. The above charging cable identification information is stored in the E-Mark chip of the charging cable identification device. The communication format of the above communication is determined by the fast charging protocol.

In this way, when the charging cable identification device is in the listening mode, the first communication port and the second communication port are both in the data receiving state. When the first target communication port of the first communication port and the second communication port receives the charging cable identification request, the second target communication port of the first communication port and the second communication port is switched to the data sending state, and the charging cable identification information is sent through the second target communication port. Therefore, the charging cable identification device can receive the identification request sent from the charger or the charging device through port multiplexing without adding an E-Mark chip, and send the identification information to the charger or the charging device, thereby improving the compatibility of the charging cable and reducing the manufacturing cost of the charging cable.

Optionally, in an embodiment of the present application, in a charging circuit in which a charger charges a charging device through a charging cable, the charger is connected to the charging device through a first communication line and a second communication line. The charger sends information to the charging device through the first communication line and receives information sent by the charging device through the second communication line.

Exemplarily, based on the above charging circuit, the above charging cable identification device receives the charging cable identification request, which may include the following two methods:

Method 1:

In the first mode, the charging cable identification device receives a charging cable identification request sent from the charger.

Exemplarily, the above steps 201 and 202 may include the following steps 201a1 and 201a2:

Step 201a1: if the first communication port receives a charging cable identification request sent by the charger, the charging cable identification device switches the second communication port from a data receiving state to a data sending state.

Step 201a2: The charging cable identification device sends charging cable identification information to the charger through the second communication port.

The first target communication port is the first communication port, and the second target communication port is the second communication port.

For example, since it takes a certain amount of time for the charging cable identification device to switch the first communication port from a data receiving state to a data sending state, the charging cable identification device can delay for a certain period of time (for example, a delay of 5ms), and after the above switching process is completed, send the charging cable identification information to the charger through the second communication port.

It should be noted that, in Mode 1, since the charger sends information to the charging device through the first communication line, the first communication port connected to the first communication line receives the information sent from the charger.

Method 2:

In the second mode, the charging cable identification device receives a charging cable identification request sent from the charging device.

Exemplarily, the above steps 201 and 202 may include the following steps 201b1 and 201b2:

Step 201b1: If the second communication port receives a charging cable identification request sent by the charger, the charging cable identification device switches the first communication port from a data receiving state to a data sending state.

Step 201b2: The charging cable identification device sends target information to the charger through the first communication port.

The first target communication port is the second communication port, and the second target communication port is the first communication port.

It should be noted that in Mode 2, since the charger receives the information sent by the charging device through the second communication line, the first communication port connected to the second communication line receives the information sent from the charger.

For example, in combination with FIG1, as shown in FIG3 (A), in the monitoring mode, the two communication ports Pin1 and Pin2 of the charging cable identification device are in the data receiving state. At this time, information sent from the charger 21 can be received, and information sent from the charging device 23 can also be received. As shown in FIG3 (B), after receiving information sent from the charger 21, the Pin2 port is switched to the data sending state, and information is sent to the charger 21 through the Pin2 port. Conversely, after receiving information sent from the charging device 23, the Pin1 port is switched to the data sending state, and information is sent to the charging device 23 through the Pin1 port.

In this way, the charging cable identification device can be compatible with both the charger and the charging device to obtain the maximum current load capacity of the charging cable, thereby improving the compatibility of the charging cable without increasing the hardware cost.

Optionally, in an embodiment of the present application, after the charging cable identification device completes a communication with the charger or charging device, in order to be able to receive the next instruction information from the charger or charging device, the charging cable identification device can switch the communication port in the data sending state to the data receiving state after receiving the control instruction from the charger or charging device.

Exemplarily, after the above step 202, the charging cable identification method provided in the embodiment of the present application may further include the following step 203a1 or step 203a2:

Step 203a1: If the first target communication port receives the first instruction, the charging cable identification device switches the second target communication port from a data sending state to a data receiving state.

Step 203a2: If the first target communication port does not receive the first instruction within a preset time, the charging cable identification device controls the charging cable identification device to enter a sleep mode.

Exemplarily, the first instruction is used to instruct the charging cable identification device to enter the listening mode. In some cases, after the charger or charging device completes the communication with the charging cable identification device, it does not send the first instruction to the charging cable identification device. At this time, after no information is received within a preset time, the charging cable identification device enters the sleep mode.

In this way, the charging cable identification device can enter the monitoring mode after completing the communication with the charger or the charging device and receiving the control instruction of the charger or the charging device, so as to facilitate the next communication.

Optionally, in an embodiment of the present application, in order to reduce the power consumption of the charging cable identification device, especially when a mobile power supply is used to charge the charging device, the charging cable identification device can enter a sleep mode after fast charging starts.

Exemplarily, after the above step 202, the charging cable identification method provided in the embodiment of the present application may further include the following step 203b or step 203c:

Step 203b: If the charging cable identification device detects that the circuit power supply voltage of the charging cable is greater than the first preset voltage, the charging cable identification device is controlled to enter the sleep mode.

Step 203c: If the charging cable identification device detects that the circuit power supply voltage of the cable is less than the second preset voltage, the charging cable identification device is controlled to enter the monitoring mode.

The second preset voltage is smaller than the first preset voltage. The power consumption in the sleep mode is smaller than the power consumption in the monitoring mode.

Exemplarily, after the charger or charging device obtains the maximum current load of the charging cable, if the requirements of the fast charging protocol are met, the charger will quickly charge the charging device. At this time, the vcc (volt current condenser, circuit power supply voltage) of the charging cable identification device will exceed the first preset voltage, and the first preset voltage is usually 6v. The charging cable identification device can determine whether the current charging circuit is in a charging state by detecting vcc. If the current charging circuit is in a charging state, the charging cable identification device enters sleep mode, and the E-Mark chip is in sleep mode. At the same time, the charging cable identification device will also periodically detect whether vcc is less than the second preset voltage. When the charging cable identification device detects that vcc is less than the second preset voltage, it enters the monitoring mode, and the E-Mark chip is awakened.

Exemplarily, the power supply modes of the charging cable identification device include the following three:

Power supply mode 1:

In power supply mode 1, the charging cable identification device relies on the vbus cable of the TYPE-C interface for power supply.

Power supply method 2:

In power supply mode 2, the charging cable identification device relies on the vcon cable of the TYPE-C interface for power supply.

Power supply method 3:

In power supply mode 3, the charging cable identification device can also be powered by a separate power supply pin of the TYPE-A interface.

It should be noted that the charging cable identification method provided in the embodiment of the present application is not only applicable to the TYPE-C interface, but also to other types of interfaces, such as the TYPE-A interface.

In this way, when the preset conditions are met, the charging cable identification device enters the sleep mode to reduce power consumption.

In the charging cable identification method provided in the embodiment of the present application, the charging cable identification device is in the monitoring mode, the first communication port and the second communication port are both in the data receiving state, and when the first target communication port of the first communication port and the second communication port receives the charging cable identification request, the second target communication port of the first communication port and the second communication port is switched to the data sending state, and the charging cable identification information is sent through the second target communication port, so that the charging cable identification device can receive the identification request sent from the charger or the charging device through port multiplexing without adding an E-Mark chip, and send the identification information to the charger or the charging device, thereby improving the compatibility of the charging cable and reducing the manufacturing cost of the charging cable. At the same time, when the preset conditions are met, the charging cable identification device automatically enters the sleep mode to reduce power consumption.

It should be noted that the charging cable identification method provided in the embodiment of the present application can be executed by a charging cable identification device, or a control module in the charging cable identification device for executing the charging cable identification method. In the embodiment of the present application, the charging cable identification device provided in the embodiment of the present application is described by taking the charging cable identification device executing the charging cable identification method as an example.

It should be noted that in the embodiments of the present application, the charging cable identification methods shown in the above-mentioned method drawings are all illustrated by taking one of the drawings in the embodiments of the present application as an example. In specific implementation, the charging cable identification methods shown in the above-mentioned method drawings can also be implemented in combination with any other drawings that can be combined as shown in the above-mentioned embodiments, which will not be repeated here.
