Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The charging cable identification method provided by the embodiment of the application can be applied to a scene of charging electronic equipment.
For example, in the related art, each terminal manufacturer has its own private fast charging protocol, and part of the fast charging protocol may increase the charging current, and in order to ensure charging safety, when performing fast charging at high current (typically, the fast charging protocol with the charging current greater than 3A), a charger or a charging device (e.g., a mobile phone, a tablet, etc.) may first send an identification information acquisition request to a control module in the charging cable, so as to acquire the maximum current load capability of the charging cable. As shown in fig. 1, the charging circuit in the related art includes 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 with the charging device through D + and D-of the TYPE-C interface, and performs data communication through D + and D-. And the charger 11 sends information to the charging device 13 through the D + cable, and the charger 11 receives the information sent by the charging device 13 through the D-cable. The control module 12 includes two communication ports, which are respectively connected to the D + and D-cables, and since the data transmission directions of D + and D-are both unidirectional transmission, in general, two communication ports of the E-Mark chip are disposed on the control module, one communication port is used for receiving data, and the other communication port is used for sending data.
However, due to the proprietary protocol of each manufacturer, there are manufacturers that obtain the maximum current load capability of the charging cable by the charger and manufacturers that obtain the maximum current load capability of the charging cable by the charging device. And after the maximum current load capacity of the charging cable meets the requirement of the quick charging protocol, the charger quickly charges the charging equipment. As shown in fig. 1 (a), a flowchart for acquiring the maximum current load capability of the charging cable for the charger is shown, 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 capability of the charging cable to the charger 11 through the Pin2 port. As shown in (B) of fig. 1, a flowchart for acquiring the maximum current load capability of the charging cable for the charging device is shown, 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 capability of the charging cable to the charging device 13 through the Pin2 port. It can be seen that one E-Mark chip can only satisfy one type of fast charge protocol, and if the two types of fast charge protocols are compatible, in the related art, two E-Mark chips are usually provided, however, since the cost of the E-Mark chip is high, in order to reduce the cost, the scheme of one E-Mark chip is usually adopted, which results in poor compatibility of the charging cable.
To solve the problem, in the technical solution provided in the embodiment of the present application, when the control module is in the default state, both the two communication ports of the E-Mark chip are in the data receiving state, and when one of the Pin1 port and the Pin2 port receives the identification request of the charging cable, the control module switches the other communication port to the data sending state and sends the identification information of the charging cable through the port, so that the control module of the charging cable can receive the identification request sent from the charger or the charging device and send the identification information to the charger or the charging device in a port multiplexing manner without increasing the E-Mark chip, thereby improving the compatibility of the charging cable and reducing the manufacturing cost of the charging cable. And after the data transmission is finished, the control module enters a sleep mode to reduce the power consumption.
The charging cable identification method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
As shown in fig. 2, a charging cable identification method provided in an embodiment of the present application is applied to a charging cable identification device, where the charging cable identification device includes a first communication port and a second communication port, and the method may include the following steps 201 and 202:
in step 201, under the condition that the charging cable identification apparatus is in the monitoring mode, if the first target communication port receives the charging cable identification request, the charging cable identification apparatus switches the second target communication port from the data receiving state to the data transmitting state.
For example, the charging cable identification device may be an E-Mark chip disposed in a charging cable, or an integrated circuit on which the E-Mark chip is mounted, where the E-Mark chip includes two communication ports, and unlike the related art, one of the two communication ports of the E-Mark chip is used for receiving data, and the other is used for transmitting data.
Wherein 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. And in the monitoring mode, the first communication port and the second communication port are both in a data receiving state.
For example, when a user uses a charging cable containing the charging cable identification device to perform charging, in order to prevent the charging current from exceeding the maximum carrying capacity of the charging cable, which creates a safety hazard, before performing charging, the charger or the charging device needs to send a charging cable identification request to the charging cable identification device, where the request is used to obtain the current carrying capacity of the charging cable. Since it is not clear whether the request is sent by the charger or the charging device before the charging cable identification apparatus receives the request, it is possible to set both the two communication ports of the charging cable identification apparatus to the data receiving state, and after the charging cable identification apparatus receives the request, the charging cable identification apparatus switches the data transmission state of the other communication port (i.e., the second target communication port) of the two communication ports except for the first target communication port that received the request from the data receiving state to the data transmitting state. Thereafter, the charging cable identification means transmits the charging cable identification information to the charger or the charging device through the second target communication port.
The charging cable identification request may be used to obtain maximum withstand voltage information of the charging cable, cable impedance information, and the like. The charging cable identification information is stored in an E-Mark chip of the charging cable identification device. The communication format of the communication is determined by the fast charging protocol.
Therefore, when 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 after 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 by the charger or the charging equipment in a port multiplexing mode without increasing an E-Mark chip, and send the identification information to the charger or the charging equipment, the compatibility of the charging cable is improved, and the manufacturing cost of the charging cable is reduced.
Optionally, in this embodiment of the 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 equipment through the first communication line, and receives the information sent by the charging equipment through the second communication line.
For example, based on the charging circuit, the charging cable identification device receives a charging cable identification request, and the following two ways may be included:
mode 1:
in the aspect 1, the charging cable identification device receives a charging cable identification request transmitted from the charger.
Illustratively, the steps 201 and 202 may include the following steps 201a1 and 201a 2:
in step 201a1, when the first communication port receives a charging cable identification request transmitted by the charger, the charging cable identification device switches the second communication port from the data reception state to the data transmission state.
Step 201a2, the charging cable identification means sends charging cable identification information to the charger through the second communication port.
The first target communication port is a first communication port, and the second target communication port is a second communication port.
For example, since it takes a certain time for the charging cable identification device to switch the first communication port from the data receiving state to the data transmitting state, the charging cable identification device may delay for a certain time (for example, delay for 5ms), and after the switching process is completed, the charging cable identification information may be transmitted to the charger through the second communication port.
In the aspect 1, since the charger transmits information to the charging device through the first communication line, the first communication port connected to the first communication line receives the information transmitted from the charger.
Mode 2:
in the aspect 2, the charging cable identification device receives a charging cable identification request transmitted from the charging apparatus.
Illustratively, the steps 201 and 202 may include the following steps 201b1 and 201b 2:
in step 201b1, when the second communication port receives the charging cable identification request sent by the charger, the charging cable identification device switches the first communication port from the data receiving state to the data sending state.
Step 201b2, the charging cable identification device sends the target information to the charger through the first communication port.
The first target communication port is a second communication port, and the second target communication port is a first communication port.
In the embodiment 2, since the charger receives the information transmitted from the charging device through the second communication line, the first communication port connected to the second communication line receives the information transmitted from the charger.
For example, referring to fig. 1, as shown in (a) of fig. 3, in the listening mode, the two communication ports Pin1 and Pin2 of the charging cable identification apparatus are in a data receiving state, and at this time, the information transmitted from the charger 21 may be received, and the information transmitted from the charging device 23 may also be received. As shown in fig. 3 (B), upon receiving the information transmitted from the charger 21, the Pin2 port is switched to the data transmission state, and the information is transmitted to the charger 21 through the Pin2 port. On the contrary, when receiving the information transmitted from the charging device 23, the Pin1 port is switched to the data transmission state, and the information is transmitted to the charging device 23 through the Pin1 port.
Therefore, the charging cable identification device can be compatible with two modes of a charger and a charging device for acquiring the maximum current load capacity of the charging cable, and the compatibility of the charging cable is improved while the hardware cost is not increased.
Optionally, in this embodiment of the application, after the charging cable identification apparatus completes one communication with the charger or the charging device, in order to be able to receive next instruction information of the charger or the charging device, the charging cable identification apparatus may switch the communication port in the data transmission state to the data reception state after receiving a control instruction of the charger or the charging device.
For example, after the step 202, the method for identifying a charging cable according to the embodiment of the present application may further include the following step 203a1 or step 203a 2:
in step 203a1, when the first target communication port receives the first command, the charging cable identification device switches the second target communication port from the data transmission state to the data reception state.
Step 203a2, if the first target communication port does not receive the first command within a preset time, the charging cable identification device controls the charging cable identification device to enter a sleep mode.
Illustratively, the first instruction is used for instructing the charging cable identification device to enter a listening mode. In some cases, the charger or the charging device does not send the first instruction to the charging cable identification device after completing communication with the charging cable identification device, and at this time, the charging cable identification device enters the sleep mode after not receiving any information within a preset time.
Therefore, the charging cable identification device can complete communication with the charger or the charging equipment and enter a monitoring mode after receiving a control command of the charger or the charging equipment, so that the next communication is facilitated.
Optionally, in this embodiment of the application, in order to reduce power consumption of the charging cable identification device, especially in a case where the mobile power source is used to charge the charging device, the charging cable identification device may enter the sleep mode after the quick charging is started.
For example, after the step 202, the method for identifying a charging cable according to the embodiment of the present application may further include the following step 203b or step 203 c:
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, controlling the charging cable identification device to enter a 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, controlling the charging cable identification device to enter a monitoring mode.
The second preset voltage is smaller than the first preset voltage. The power consumption of the sleep mode is less than the power consumption of the listening mode.
For example, after the charger or the charging device obtains the maximum current load of the charging cable, if the requirement of the fast charging protocol is met, the charger performs fast charging on the charging device, and at this time, a vcc (voltage supply voltage) of the charging cable identification device exceeds a first preset voltage, where the first preset voltage is typically 6 v. The charging cable identification device may determine whether the current charging circuit is in a charging state by detecting vcc. And if the current charging circuit is in a charging state, the charging cable identification device enters a sleep mode, and at the moment, the E-Mark chip is in sleep. Meanwhile, the charging cable identification device can also periodically detect whether the vcc is smaller than a second preset voltage, when the charging cable identification device detects that the vcc is smaller than the second preset voltage, the monitoring mode is entered, and at the moment, the E-Mark chip is awakened.
For example, the power supply method of the charging cable identification device includes the following three methods:
power supply method 1:
in the power supply mode 1, the charging cable recognition device is powered by a vbus cable of the TYPE-C interface.
Power supply method 2:
in the power supply method 2, the charging cable identification device is powered by the vcon cable of the TYPE-C interface.
Power supply method 3:
in power supply mode 3, the charging cable identification device can also supply power by means of a power supply pin independent 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 a TYPE-C interface, but also applicable to other TYPEs of interfaces, such as a TYPE-a interface.
Therefore, under the condition that the preset condition is met, the charging cable identification device enters the sleep mode, and power consumption is reduced.
In the charging cable identification method provided by the embodiment of the application, when 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, when a first target communication port of the first communication port and the second communication port receives a charging cable identification request, by switching the second target communication port of the first communication port and the second communication port to the data transmission state, and the charging cable identification information is sent through the second target communication port, so that the charging cable identification device can identify the charging cable through the port multiplexing mode under the condition of not increasing an E-Mark chip, the identification request sent by the charger or the charging equipment can be received, and the identification information is sent to the charger or the charging equipment, so that the compatibility of the charging cable is improved, and the manufacturing cost of the charging cable is reduced. Meanwhile, under the condition that the preset condition is met, the charging cable identification device automatically enters the sleep mode, and power consumption is reduced.
It should be noted that, in the charging cable identification method provided in the embodiment of the present application, the execution main body may be 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, a charging cable identification method executed by a charging cable identification device is taken as an example, and the charging cable identification device provided in the embodiment of the present application is described.
