为了使本技术领域的人员更清楚地理解本申请方案，下面以电子设备为PC说明目前包含Type-C接口的电子设备充电和对外充电时的实现方式。以下说明中的外部充电器也即充电器。In order to enable those skilled in the art to understand the solution of the present application more clearly, the following uses the electronic device as a PC to illustrate the current implementation of charging an electronic device including a Type-C interface and external charging. The external charger in the following description is also the charger.

参见图2，该图为本申请实施例提供的PC的Type-C接口充电或对外充电的电路图。Referring to FIG. 2 , this figure is a circuit diagram of the Type-C interface charging or external charging of the PC provided by the embodiment of the present application.

PC包括两个Type-C接口，分别为第一Type-C接口21以及第二Type-C接口22。电子设备还包括充电电路23、控制器24、功率传输模块(Power Delivery，PD)模块25以及功率变换电路26。The PC includes two Type-C interfaces, namely a first Type-C interface 21 and a second Type-C interface 22 . The electronic device further includes a chargingcircuit 23 , acontroller 24 , a power delivery module (Power Delivery, PD)module 25 and apower conversion circuit 26 .

以PC设备采用第一Type-C接口21连接外部充电器进行充电，并且采用第二Type-C接口22连接外部设备并为外部设备供电为例进行说明。The PC device is connected to an external charger through the first Type-C interface 21 for charging, and the second Type-C interface 22 is used to connect to the external device and provide power for the external device as an example for illustration.

当第一Type-C接口21连接外部充电器(图中未示出)进行充电时，外部充电器和PC之间通过线缆实现握手。下面具体说明PD供电协议的具体通讯流程。When the first Type-C interface 21 is connected to an external charger (not shown in the figure) for charging, a handshake is implemented between the external charger and the PC via a cable. The specific communication process of the PD power supply protocol will be described in detail below.

在充电过程中，外部充电器用于提供电源，为充电端(用Source表示)；PC设备用于接收供电，为用电设备端(用Sink表示)。During the charging process, the external charger is used to provide power, which is the charging end (indicated by Source); the PC device is used to receive power supply, and is the end of the electric device (indicated by Sink).

Type-C接口是供电方时，则设备的USB角色为下行端口(Downstream FacingPart，DFP)；Type-C接口是耗电方时，则设备的USB角色为上行端口(Upstream FacingPart，UFP)。下行端口工作状态为USB主机，上行端口工作工状态为USB外设备。When the Type-C interface is the power supply side, the USB role of the device is the Downstream FacingPart (DFP); when the Type-C interface is the power consumer, the USB role of the device is the Upstream FacingPart (UFP). The working state of the downstream port is USB host, and the working state of the upstream port is USB external device.

充电过程中，信息的发送方发送信息给接收方后，接收方接收到信息并确认循环冗余校验(Cyclic Redundancy Check，CRC)无误后，应该向发送方回复GoodCRC消息，以表示自己正确无误地收到发送方发过来的消息。否则发送方等待超时（超时阈值例如可以设置为约0.9~1.1ms的时间长度)，重新发送原消息。如果多次发送(例如三次发送)后发送方都未收到GoodCRC，则认为消息发送失败。During the charging process, after the sender of the information sends the information to the receiver, and the receiver receives the information and confirms that the cyclic redundancy check (Cyclic Redundancy Check, CRC) is correct, it should reply a GoodCRC message to the sender to indicate that it is correct receive the message from the sender. Otherwise, the sender waits for a timeout (the timeout threshold can be set to a time length of about 0.9-1.1 ms, for example), and resends the original message. If the sender does not receive the GoodCRC after multiple sendings (for example, three sendings), it is considered that the message sending has failed.

外部充电器通过第一Type-C接口21为PC设备充电的过程如下：The process of charging the PC device by the external charger through the first Type-C interface 21 is as follows:

外部充电器和PC设备通过第一Type-C接口21的CC pin握手，将外部充电器识别为Source设备，PC识别为Sink设备。The external charger and the PC device shake hands through the CC pin of the first Type-C interface 21, and identify the external charger as a Source device, and the PC as a Sink device.

功率传输模块25会拉高对应第一Type-C接口21口的通用型输入输出(General-purpose input/output，GPIO)接口，也即拉高PD_GPIO1。Thepower transmission module 25 will pull up the general-purpose input/output (GPIO) interface corresponding to the first Type-C interface 21 , that is, pull up PD_GPIO1 .

以L1所示通路中的S1和S2为N型金属氧化物半导体场效应晶体管 (N-Metal-Oxide-Semiconductor Filed Effect Transistor，N-MOSFET，以下简称NMOS管)为例。Take for example that S1 and S2 in the path indicated by L1 are N-type Metal-Oxide-Semiconductor Field Effect Transistors (N-MOSFETs, hereinafter referred to as NMOS transistors).

拉高PD_GPIO1后，S1和S2均被打开，外部充电器提供的电压电流会通过S1、S2和充电电路23后给PC设备的系统供电，以及给PC设备的电池充电。After PD_GPIO1 is pulled high, both S1 and S2 are turned on, and the voltage and current provided by the external charger will pass through S1, S2 and the chargingcircuit 23 to supply power to the system of the PC device and charge the battery of the PC device.

目前的设计方案为，第一Type-C接口21和第二Type-C接口22的线路经过NMOS管后连为一条通路，然后连接充电电路23的输入端。所以每条通路放两个NMOS管目的是为了防止一条通路在充电时将电流倒灌入另一个Type-C接口的通路。当前PC设备的外部充电器的充电功率可以达到在100W及以上。The current design scheme is that the lines of the first Type-C interface 21 and the second Type-C interface 22 pass through an NMOS transistor and then connect to an input terminal of the chargingcircuit 23 . Therefore, the purpose of placing two NMOS transistors in each channel is to prevent one channel from pouring current into another Type-C interface channel when charging. The charging power of the external charger of the current PC equipment can reach 100W and above.

第一Type-C接口21连接外部充电器或者第一Type-C接口21未连接外部充电器时，PC设备对外充电通路为L2。When the first Type-C interface 21 is connected to an external charger or the first Type-C interface 21 is not connected to an external charger, the external charging path of the PC device is L2.

以第二Type-C接口22口接入其它PC、手机、U盘、OTG等耗电方为例，耗电方会和PC设备通过第二Type-C接口22的CC pin握手。将当前PC识别为Source设备，接入第二Type-C接口22的设备识别为Sink设备时，功率传输模块25会导通内部与第二Type-C接口22对应的开关(switch)，也即导通开关SW2。Taking the second Type-C interface 22 to connect to other power consumers such as PC, mobile phone, U disk, OTG, etc. as an example, the power consumer will shake hands with the PC device through the CC pin of the second Type-C interface 22 . When the current PC is identified as a Source device and the device connected to the second Type-C interface 22 is identified as a Sink device, thepower transmission module 25 will turn on the internal switch corresponding to the second Type-C interface 22, that is, The switch SW2 is turned on.

SW2导通后，功率变换电路26进行升压变换以输出5V的电压，对接入的Sink设备提供电源，这个电源根据PD协议，最大只有5V/3A。After SW2 is turned on, thepower conversion circuit 26 performs step-up conversion to output a voltage of 5V to provide power to the connected Sink device. According to the PD protocol, the maximum power is only 5V/3A.

对于上述的对PC充电和PC对外部Sink设备充电时，对于Type-C接口，都是接到VBUS的Pin脚。For the above-mentioned charging of the PC and the charging of the external Sink device by the PC, the Type-C interface is connected to the Pin of VBUS.

目前，由于PC设备最大只能对连接的外部Sink设备提供5V/3A的充电电源，也即最大对外充电功率为15W。对于接入U盘，USB OTG等设备或者手机传输文件场景的应用可以适配，但是受到PC产品最大输出功率的限制，无法满足用户利用PC产品对PC、手机等电子设备实现更高功率的快速充电的需求。例如：用户当前只有一个外部充电器，又需要对两个PC，或者PC和手机等2个设备同时快速充电的场景，目前的方案只能对一个设备进行大功率的快速充电，另一个设备只能进行低功率的充电。At present, since the PC device can only provide a maximum charging power of 5V/3A to the connected external sink device, that is, the maximum external charging power is 15W. It can be adapted to the application of accessing U disk, USB OTG and other devices or mobile phone file transfer scenarios, but limited by the maximum output power of PC products, it cannot meet the needs of users to use PC products to achieve higher power quickly for electronic devices such as PCs and mobile phones. charging needs. For example: the user currently only has one external charger, and needs to quickly charge two PCs, or two devices such as a PC and a mobile phone at the same time, the current solution can only perform high-power fast charging for one device, and the other device only Low-power charging is possible.

为了解决以上技术问题，本申请提供了一种电子设备及充电方法，使得PC设备能够对于Type-C接口连接的其他电子设备进行大功率的快速充电，能够在用户当前只有一个外部充电器时，实现对两个PC，或者PC和手机等2个设备同时快速充电，提升了用户的体验，并且方案的硬件成本低，实用性高。In order to solve the above technical problems, this application provides an electronic device and a charging method, so that the PC device can perform high-power fast charging for other electronic devices connected to the Type-C interface, and when the user currently only has one external charger, Realize simultaneous fast charging of two PCs, or two devices such as a PC and a mobile phone, which improves the user experience, and the hardware cost of the solution is low and the practicability is high.

本申请的技术方案未在现有的架构上增加新的集成电路(integrated circuit，IC)，仅增加了二极管电路28，并通过复用目前PC设备上的芯片即可实现，因此结构简单，硬件成本较低。The technical solution of the present application does not add a new integrated circuit (integrated circuit, IC) on the existing architecture, only increases thediode circuit 28, and can realize by multiplexing the chips on the current PC equipment, so the structure is simple, the hardware The cost is lower.

二极管电路28包括第一二极管D1、第二二极管D2、第三二极管D3以及第四二极管D4。Thediode circuit 28 includes a first diode D1 , a second diode D2 , a third diode D3 and a fourth diode D4 .

继续以S1-S4为NMOS管为例进行说明。Continue to take S1-S4 as an example of NMOS transistors for illustration.

PD_GPIO1连接第一二极管D1的阳极，第一二极管D1的阴极连接S1和S2的栅极(Gate)PD_GPIO1 is connected to the anode of the first diode D1, and the cathode of the first diode D1 is connected to the gates (Gate) of S1 and S2

PD_GPIO1连接第二二极管D2的阳极，第一二极管D2的阴极连接S3和S4的栅极。PD_GPIO1 is connected to the anode of the second diode D2, and the cathode of the first diode D2 is connected to the gates of S3 and S4.

EC_GPIO2连接第四二极管D4的阴极，也即连接S3和S4的栅极。EC_GPIO2 is connected to the cathode of the fourth diode D4, that is, to the gates of S3 and S4.

第一二极管D1、第二二极管D2、第三二极管D3以及第四二极管D4的作用是隔离四个GPIO口，防止四个GPIO口的信号之间互相影响。The functions of the first diode D1, the second diode D2, the third diode D3 and the fourth diode D4 are to isolate the four GPIO ports and prevent the signals of the four GPIO ports from influencing each other.

继续以第一Type-C接口21连接外部充电器，对PC设备进行充电为例进行说明。Continue to take the first Type-C interface 21 to connect an external charger to charge the PC device as an example for illustration.

当第一Type-C接口21连接外部充电器时，功率传输模块25会拉高PD_GPIO1，进而使得S1和S2的栅极连接高电平，S1和S2导通。同时，路易通路的PD_GPIO2维持拉低状态，以使S3和S4的栅极连接低电平，S3和S4关闭。控制器24的两个GPIO口均处于拉低状态。When the first Type-C interface 21 is connected to an external charger, thepower transmission module 25 will pull up PD_GPIO1, so that the gates of S1 and S2 are connected to a high level, and S1 and S2 are turned on. At the same time, the PD_GPIO2 of the Louisiana path remains low, so that the gates of S3 and S4 are connected to low level, and S3 and S4 are turned off. The two GPIO ports of thecontroller 24 are both in a low state.

此时外部充电器通过第一Type-C接口21、S1、S2和充电电路23后为PC设备供电以及为PC设备的电池进行充电。S3和S4的背靠背连接方式可以防止当前正在充电通路的电压电流倒灌入第二Type-C接口22。At this time, the external charger supplies power to the PC device and charges the battery of the PC device through the first Type-C interface 21 , S1 , S2 and the chargingcircuit 23 . The back-to-back connection of S3 and S4 can prevent the voltage and current currently being charged into the second Type-C interface 22 .

下面说明在充电的过程中，第二Type-C接口22接入PC设备或者手机等Sink设备时，PC设备对Sink实现快速充电的流程。In the charging process, when the second Type-C interface 22 is connected to a sink device such as a PC device or a mobile phone, the process of fast charging the sink by the PC device will be described below.

参见图4，该图为本申请实施例提供的PC设备对Sink设备进行快速充电的流程图一。Referring to FIG. 4 , this figure is a first flowchart of fast charging of a sink device by a PC device provided in an embodiment of the present application.

第二Type-C接口22接入Sink设备时，功率传输模块和Sink设备通过第二Type-C接口22的CC pin握手，确定自身为Source设备，接入的为Sink设备。功率传输模块打开与第二Type-C接口22对应的开关，也即打开SW2，先对Sink设备进行低规格的充电。When the second Type-C interface 22 is connected to the sink device, the power transmission module and the sink device shake hands through the CC pin of the second Type-C interface 22 to determine that it is the source device and the connected one is the sink device. The power transmission module turns on the switch corresponding to the second Type-C interface 22, that is, turns on SW2, and first charges the Sink device with a low specification.

在一些实施例中，PC设备此时的对外充电规格为：充电电压5V，充电电流3A。In some embodiments, the external charging specifications of the PC device at this time are: chargingvoltage 5V, charging current 3A.

其中，I2C总线是一种双向同步串行总线，包括一根串行数据线(serial dataline，SDA)和一根串行时钟线(derail clock line，SCL)，再次不多做赘述。控制器24也可以通过I2C总线控制充电电路23的工作。Among them, the I2C bus is a bidirectional synchronous serial bus, including a serial data line (serial data line, SDA) and a serial clock line (derail clock line, SCL), and again will not repeat them here. Thecontroller 24 can also control the operation of the chargingcircuit 23 through the I2C bus.

S13：控制器告知CPU有 Sink设备接入。S13: The controller informs the CPU that a Sink device is connected.

控制器通过增强型串行外设接口(enhanced serial peripheral interface，eSPI)总线告知CPU有 Sink设备接入。The controller informs the CPU that a Sink device is connected through an enhanced serial peripheral interface (enhanced serial peripheral interface, eSPI) bus.

S14：CPU控制PC设备在操作系统界面进行弹窗提示。S14: The CPU controls the PC device to prompt a pop-up window on the operating system interface.

PC设备的操作系统(Operating System，OS)界面可以通过弹窗的形式，提示用户选择是否需要对接入的Sink设备进行快速充电。The operating system (Operating System, OS) interface of the PC device may prompt the user to select whether to fast charge the connected Sink device in the form of a pop-up window.

参见图5，该图为本申请实施例提供的弹窗界面的示意图一。Refer to FIG. 5 , which is a first schematic diagram of a pop-up window interface provided by an embodiment of the present application.

用户可以通过OS界面的弹窗功能选择是否需要开启对Sink设备的快速充电。可以理解的是，以上的弹窗界面仅是一种可能的实现方式，并不构成对于本申请实现方式的具体限定。弹窗界面的大小、布局还可以采用其它的方式，在此不再赘述。The user can choose whether to enable fast charging of the Sink device through the pop-up function of the OS interface. It can be understood that the above pop-up window interface is only a possible implementation manner, and does not constitute a specific limitation on the implementation manner of the present application. The size and layout of the pop-up window interface can also adopt other methods, which will not be repeated here.

可以理解的是，用户还可以在弹窗界面或者PC设备的与电源控制相关的设置菜单中设置默认的配置选项，例如设置总是询问，则每当PC设备通过Type-C接口连接Sink设备时，PC设备均会进行弹窗询问；又例如可以设置为默认启动对Sink设备进行快速充电，则每当PC设备通过Type-C接口连接Sink设备时，PC设备不再进行弹窗提示，而是自动启动对Sink设备的快速充电流程；在例如可以设置为默认关闭对Sink设备的快速充电功能，则每当PC设备通过Type-C接口连接Sink设备时，PC设备不再进行弹窗提示，且不启动对Sink设备的快速充电流程。It is understandable that the user can also set the default configuration options in the pop-up window interface or the power control-related setting menu of the PC device. , the PC device will pop-up to ask; for example, it can be set to enable fast charging of the sink device by default, then whenever the PC device connects to the sink device through the Type-C interface, the PC device will no longer prompt the pop-up window, but Automatically start the fast charging process for the sink device; for example, it can be set to disable the fast charging function for the sink device by default, then whenever the PC device connects to the sink device through the Type-C interface, the PC device will no longer prompt the pop-up window, and Do not start the fast charging process for the sink device.

S15：用户选择对Sink设备进行快速充电。S15: The user chooses to fast charge the Sink device.

可以理解的是，用户也可以在弹窗界面选择不对Sink设备进行快速充电。例如用户直接在弹窗界面选择不对Sink设备进行快速充电，或者用户关闭弹窗界面未进行操作，均可以视作用户触发了不对Sink设备进行快速充电的选择。此时则不再继续进行后续的流程，PC设备维持对Sink设备的低功率充电。It is understandable that the user can also choose not to fast charge the Sink device on the pop-up window interface. For example, the user directly chooses not to perform fast charging on the Sink device in the pop-up window interface, or the user closes the pop-up window interface without performing any operation, which can be regarded as the user triggering the selection not to perform fast charging on the Sink device. At this time, the subsequent process is not continued, and the PC device maintains the low-power charging of the Sink device.

表1：充电日志表Table 1: Charging log table

S24：功率传输模块断开内部对应的开关。S24: The power transmission module turns off the corresponding internal switch.

也即功率传输模块25控制SW2断开，停止对Sink设备进行的低功率充电。That is to say, thepower transmission module 25 controls SW2 to turn off, and stops the low-power charging of the Sink device.

S25：功率传输模块告知控制器开始对Sink设备进行快速充电。S25: the power transmission module notifies the controller to start fast charging the Sink device.

功率传输模块25通过I2C总线告知控制器Sink设备已经准备好，开始对Sink设备进行快速充电。Thepower transmission module 25 notifies the controller that the Sink device is ready through the I2C bus, and starts fast charging the Sink device.

S26：控制器拉高对应的GPIO管脚。S26: the controller pulls up the corresponding GPIO pin.

参见图6，该图为本申请实施例提供的弹窗界面的示意图二。Refer to FIG. 6 , which is a second schematic diagram of the pop-up window interface provided by the embodiment of the present application.

可以通过OS界面的弹窗功能向用户展示当前已经开启对Sink设备的快速充电。The pop-up function of the OS interface can be used to show the user that the fast charging of the Sink device is currently enabled.

可以理解的是，以上的弹窗界面仅是一种可能的实现方式，并不构成对于本申请实现方式的具体限定。弹窗界面的大小、布局还可以采用其它的方式，在此不再赘述。It can be understood that the above pop-up window interface is only a possible implementation manner, and does not constitute a specific limitation on the implementation manner of the present application. The size and layout of the pop-up window interface can also adopt other methods, which will not be repeated here.

进一步的，弹窗界面上还可以包括“是否停止对该设备进行快速充电”的选项，以供用户根据需求结束对于Sink设备的快速充电。Further, the pop-up window interface may also include an option of "whether to stop the fast charging of the device", so that the user can end the fast charging of the Sink device according to the requirement.

低功率充电时的充电规格为第一充电规格，外部充电器的充电规格为第二充电规格，该第二充电规格大于第一充电规格，因此当S3和S4断开后，实现了对于Sink设备的快速充电。The charging specification for low-power charging is the first charging specification, and the charging specification for the external charger is the second charging specification, which is greater than the first charging specification. Therefore, when S3 and S4 are disconnected, the Sink device is realized fast charging.

实际应用中，可能存在Sink设备不支持快速充电，或者不支持PC设备提供的充电规格。此时PC设备实施的流程参见下图进行说明。In practical applications, there may be that the sink device does not support fast charging, or does not support the charging specification provided by the PC device. At this time, the process implemented by the PC device is described in the figure below.

一并参见图3和图7。其中，图7为本申请实施例提供的快速充电失败时的流程图。See Figure 3 and Figure 7 together. Wherein, FIG. 7 is a flow chart when the fast charging fails provided by the embodiment of the present application.

S201：功率传输模块确认Sink设备不支持Source_Capabilites消息中携带的充电规格。S201: The power transmission module confirms that the Sink device does not support the charging specification carried in the Source_Capabilites message.

当第二Type-C接口22接入的Sink设备不支持Source_Capabilites消息中携带的充电规格时，在一种可能的实现方式中，此时功率传输模块无法接受到Sink设备发送的Request消息，此时功率传输模块可以向Sink设备再次发送相同的Source_Capabilites消息，继续等待Sink设备回应，如果经过一共第一预设次数的发送后，还是未接收到Sink设备回复的GoodCRC消息，或者未接收到Sink设备回复的Request消息，则确定Sink设备不支持Source_Capabilites消息中携带的充电规格；在另一种可能的实现方式中，功率传输模块能够接收到Sink设备发送的指示不接受充电规格的信息，则功率传输模块确定Sink设备不支持Source_Capabilites消息中携带的充电规格。When the Sink device connected to the second Type-C interface 22 does not support the charging specification carried in the Source_Capabilites message, in a possible implementation, the power transmission module cannot receive the Request message sent by the Sink device at this time. The power transmission module can send the same Source_Capabilites message to the sink device again, and continue to wait for the sink device to respond. If after a total of the first preset times of sending, the GoodCRC message replied by the sink device is still not received, or the sink device reply is not received Request message, then it is determined that the Sink device does not support the charging specification carried in the Source_Capabilites message; It is determined that the sink device does not support the charging specification carried in the Source_Capabilites message.

本申请实施例对第一预设次数不作具体限定，在一些实施例中，第一预设次数可以设置为3次。The embodiment of the present application does not specifically limit the first preset number of times, and in some embodiments, the first preset number of times may be set to 3 times.

The size and layout of the pop-up window interface can also adopt other methods, which will not be repeated here.

通过弹窗界面，告知用户当前PC设备的性能模式已开启，对Sink设备的充电方式已经由快速充电切换为低功率充电。在另一些实施例中，弹窗界面还可以包括“是否关闭性能模式并重启快速充电”选项，当用户选择是时，则PC设备关闭性能模式，并按照图4中S16-S28的步骤重新开启对Sink设备的快速充电。Through the pop-up window interface, the user is informed that the performance mode of the current PC device has been turned on, and the charging method for the Sink device has been switched from fast charging to low-power charging.

For example, in practical applications, the sequence of S52 can be executed after the low-power charging is turned on. When the power transmission module turns on SW2, it will notify the controller through the I2C interface that the fast charging has been turned off, and the controller will notify the CPU through the eSPI interface that the fast charging has been turned off. Then the CPU controls the PC device to pop up a window on the OS interface to prompt that the performance mode has been turned on, and the fast charging of the sink device has been turned off.

When the electronic device is fully charged, or when the power of the electronic device is greater than the preset When setting the power value, stop fast charging of electronic devices and switch to low-power charging. You can also use the pop-up window on the OS interface to prompt that the Sink device is fully charged, and the fast charging mode has been switched to low-power charging mode.

可以理解的是，对于PC设备开启性能模式、用户主动选择关闭快速充电以及Sink设备充满电的情况，均可以视作此时需要停止按照第二充电规格对Sink设备进行充电。It can be understood that, when the performance mode of the PC device is turned on, the user actively chooses to turn off fast charging, and the sink device is fully charged, it can be regarded as that it is necessary to stop charging the sink device according to the second charging specification at this time.

综上所述，利用本申请实施例提供的技术方案，在电子设备上未增加复杂的IC，仅增加了结构简单，硬件成本低的二极管，即可以使得电子设备在利用一个Type-C接口进行快速充电的同时，利用其它的Type-C接口对外部接入的Sink设备进行快速充电，也即实现了利用一个外部充电器同时对多个电子设备进行快速充电的功能，满足了用户的快速充电需求，提升了用户体验。并且该方案的硬件成本低，易于实现，具有较高的实用性。In summary, using the technical solution provided by the embodiment of the present application, no complex IC is added to the electronic device, only a diode with a simple structure and low hardware cost is added, that is, the electronic device can be connected using a Type-C interface. At the same time of fast charging, use other Type-C interfaces to quickly charge externally connected sink devices, that is, to realize the function of using an external charger to quickly charge multiple electronic devices at the same time, which meets the needs of users for fast charging. demand and improve the user experience.

参见图17，该图为本申请实施例提供的另一种电子设备的示意图。Referring to FIG. 17 , this figure is a schematic diagram of another electronic device provided by an embodiment of the present application.

该电子设备与图3所示的电子设备的区别在于，本申请实施例中的二极管电路28还包括第五二极管D5和第六二极管D6。The difference between this electronic device and the electronic device shown in FIG. 3 is that thediode circuit 28 in the embodiment of the present application further includes a fifth diode D5 and a sixth diode D6.

其中，第五二极管D5的阳极连接功率传输模块的开关SW1，第五二极管D5的阴极连接在第一Type-C接口21以及S1之间，也即阴极连接在第一Type-C接口21的VBUS上；第六二极管D6的阳极连接功率传输模块的开关SW2，第六二极管D6的阴极连接在第二Type-C接口22以及S3之间，也即阴极连接在第二Type-C接口22的VBUS上。Wherein, the anode of the fifth diode D5 is connected to the switch SW1 of the power transmission module, and the cathode of the fifth diode D5 is connected between the first Type-C interface 21 and S1, that is, the cathode is connected to the first Type-C On the VBUS of theinterface 21; the anode of the sixth diode D6 is connected to the switch SW2 of the power transmission module, and the cathode of the sixth diode D6 is connected between the second Type-C interface 22 and S3, that is, the cathode is connected to the second Type-C interface 22 and S3.

设置D5和D6的作用时，当开启对Sink设备的快速充电时，控制器可以先控制GPIO口拉高，以使S3和S4接通，此时电流和电压不会反灌至功率传输模块；然后功率传输模块控制内部的开关断开，进而避免Sink设备在由低功率充电向快速充电的过程中出现短暂掉电的情况。When setting the functions of D5 and D6, when the fast charging of the sink device is turned on, the controller can first control the GPIO port to be pulled high so that S3 and S4 are connected. At this time, the current and voltage will not be fed back to the power transmission module; Then the power transmission module controls the internal switch to be turned off, thereby avoiding the short-term power loss of the Sink device during the process from low-power charging to fast charging.

功率传输模块25打开与第二Type-C接口22对应的开关，也即打开SW2，先对Sink设备进行低规格的充电。Thepower transmission module 25 turns on the switch corresponding to the second Type-C interface 22, that is, turns on SW2, and first charges the Sink device with a low specification.

在一些实施例中，PC设备此时的对外充电规格为：充电电压5V，充电电流3A。In some embodiments, the external charging specifications of the PC device at this time are: chargingvoltage 5V, charging current 3A.

弹窗界面可以参见以上图5所示。The pop-up interface can be seen in Figure 5 above.

可以理解的是，用户还可以在弹窗界面或者PC设备的与电源控制相关的设置菜单中设置默认的配置选项，例如设置总是询问，则每当PC设备通过Type-C接口连接Sink设备时，PC设备均会进行弹窗询问；又例如可以设置为默认启动对Sink设备进行快速充电，则每当PC设备通过Type-C接口连接Sink设备时，PC设备不再进行弹窗提示，而是自动启动对Sink设备的快速充电流程；在例如可以设置为默认关闭对Sink设备的快速充电功能，则每当PC设备通过Type-C接口连接Sink设备时，PC设备不再进行弹窗提示，且不启动对Sink设备的快速充电流程。It is understandable that the user can also set the default configuration options in the pop-up window interface or the power control-related setting menu of the PC device. , the PC device will pop-up to ask; for example, it can be set to enable fast charging of the sink device by default, then whenever the PC device connects to the sink device through the Type-C interface, the PC device will no longer prompt the pop-up window, but Automatically start the fast charging process for the sink device; for example, it can be set to disable the fast charging function for the sink device by default, then whenever the PC device connects to the sink device through the Type-C interface, the PC device will no longer prompt the pop-up window, and Do not start the fast charging process for the sink device.

S65：用户选择对Sink设备进行快速充电。S65: The user chooses to fast charge the Sink device.

可以理解的是，用户也可以在弹窗界面选择不对Sink设备进行快速充电。例如用户直接在弹窗界面选择不对Sink设备进行快速充电，或者用户关闭弹窗界面未进行操作，均可以视作用户触发了不对Sink设备进行快速充电的选择。此时则不再继续进行后续的流程，PC设备维持对Sink设备的低功率充电。It is understandable that the user can also choose not to fast charge the Sink device on the pop-up window interface. For example, the user directly chooses not to perform fast charging on the Sink device in the pop-up window interface, or the user closes the pop-up window interface without performing any operation, which can be regarded as the user triggering the selection not to perform fast charging on the Sink device. At this time, the subsequent process is not continued, and the PC device maintains the low-power charging of the Sink device.

S82：CPU告知控制器停止对Sink设备进行快速充电。S82: The CPU informs the controller to stop fast charging the Sink device.

CPU通过eSPI总线告知控制器停止对Sink设备进行快速充电。The CPU informs the controller to stop fast charging the Sink device through the eSPI bus.

可以理解的是，当对Sink设备进行快速充电时，EC_GPIO2管脚拉高，PD_GPIO2管脚可以拉高也可以拉低，当PD_GPIO2管脚拉高时，停止PD_GPIO2管脚时PD_GPIO2管脚需要切换为拉低状态；当PD_GPIO2管脚拉低时，停止PD_GPIO2管脚时PD_GPIO2管脚维持拉低状态。It is understandable that when the Sink device is fast charged, the EC_GPIO2 pin is pulled high, and the PD_GPIO2 pin can be pulled high or low. When the PD_GPIO2 pin is pulled high, the PD_GPIO2 pin needs to be switched to Low state; when the PD_GPIO2 pin is low, the PD_GPIO2 pin remains low when the PD_GPIO2 pin is stopped.

When the fast charging is turned off, the controller informs the CPU that the fast charging is turned off through the eSPI interface, and then the CPU controls the PC device to prompt the performance in a pop-up window on the OS interface. mode is on and fast charging for sink devices is off.

在另一些实施例中，PC设备在对Sink设备进行快速充电的过程中，还可以与Sink设备进行交互以获取Sink设备当前的电量，当电子设备充满电时，或者当电子设备的电量大于预设电量值时，停止对电子设备进行快速充电，并且换为低功率充电，切换过程中同样是功率传输模块先控制对应的开关闭合，然后控制器再将对应的GPIO管脚拉低，以避免Sink设备出现充电短暂中断。还可以通过OS界面弹窗提示Sink设备已充满电，快速充电模式已经切换为低功率充电模式。In some other embodiments, the PC device can also interact with the Sink device to obtain the current power of the Sink device during the process of fast charging the Sink device. When the electronic device is fully charged, or when the power of the electronic device is greater than the preset When setting the power value, stop fast charging of electronic devices and switch to low power charging.
