参照图2，在本法明充电方法的一实施例中，所述充电方法包括：Referring to FIG. 2, in an embodiment of the charging method of this method, the charging method includes:
步骤S10、充电头输出预设电压；Step S10, the charging head outputs a preset voltage;
在本实施例中，执行主体可以是充电头，所述充电头内置微处理器，所述微处理器用于处理数据并控制充电头的其它芯片及/或电路实现自身功能。当所述充电头与电源连接时，可以汲取电源电能。然后通过充电头的通过内部的电压/电流处理装置(例如，变压器)及整流器等组件，将电源的高压交流电转化预设电压值的直流电。In this embodiment, the execution body may be a charging head, and the charging head has a built-in microprocessor, and the microprocessor is used to process data and control other chips and/or circuits of the charging head to realize their own functions. When the charging head is connected to a power source, it can draw power from the power source. Then, through the internal voltage/current processing device (eg, transformer) and rectifier components of the charging head, the high-voltage alternating current of the power supply is converted into direct current of a preset voltage value.
具体地，当充电头与电源接通时，输出预设电压，其中，所述预设电压可以由充电头的生产厂家自定义设置。例如，充电头常用充电电压为5V，9V或者12V，可以将预设电压设置为5V。当充电头与电源接通时，将充电头的输出电压设置为5V。Specifically, when the charging head is connected to the power source, a preset voltage is output, wherein the preset voltage can be customized and set by the manufacturer of the charging head. For example, the common charging voltage of the charging head is 5V, 9V or 12V, and the preset voltage can be set to 5V. When the charging head is connected to the power supply, set the output voltage of the charging head to 5V.
需要说明的是，所述充电头为电源转换装置，设置有输入接口和输出接口。所述输出接口可以设置为USB接口,通过USB接口可以与设置有USB连接头充电线连接。所述输入接口可以设置与插头连接，通过插头可以实现与市电连接。可以理解的是，输入接口也可以与车载电源连接。在此不限定头的输入电源的类型。例如，充电头的输入电源的类型可以是220V市电、330V市电、车载电源及/或者其它电源。It should be noted that the charging head is a power conversion device, and is provided with an input interface and an output interface. The output interface can be set as a USB interface, and can be connected with a charging line provided with a USB connector through the USB interface. The input interface can be configured to be connected with a plug, and the connection with the commercial power can be realized through the plug. It can be understood that the input interface can also be connected to the vehicle power supply. The type of input power to the head is not limited here. For example, the type of input power of the charging head may be 220V commercial power, 330V commercial power, vehicle power and/or other power sources.
步骤S20、检测所述充电头的正数据线接线端子的电平值；Step S20, detecting the level value of the positive data line terminal of the charging head;
在本实施例中，当充电头的输出接口设置为USB接口时，其接口设置有电源线接线端子、地线接线端子及差分信号线接线端子。其中，差分信号线接线端子包括正数据线(DP，Data Positive)接线端子和负信号线(DM，Data Minus)接线端子。使得充电头可以通过接线端子与USB线的一端连接。USB线的另一端分别与便携设备的USB接口连接。In this embodiment, when the output interface of the charging head is set as a USB interface, the interface is provided with a power wire connection terminal, a ground wire connection terminal and a differential signal wire connection terminal. Wherein, the differential signal wire terminal includes a positive data wire (DP, Data Positive) terminal and a negative signal wire (DM, Data Minus) terminal. So that the charging head can be connected with one end of the USB cable through the wiring terminal. The other ends of the USB cables are respectively connected to the USB ports of the portable device.
进一步地，充电头还设置有电压检测组件，通过所述电压检测组件可以实时检测正数据线接线端子上的电压信号。当通过电压检测组件确定正数据线接线端子上的电平值时。根据所述电平值查询关联的兼容电压。其中，电平信号与兼容电压之间的关联信息可以预先保存在充电头的处理器可以读取的存储介质中。例如，电平值分别为1V、2V和3V时，其关联的兼容电压可以分别为5V，9V和12V。因此，当处理器通过电压检测组件检测到正数据线接线端子上的电平值为1V时，可以判定当前通过USB连接线连接的便携设备的兼容电压为5V，当检测正数据线接线端子上的电平值为2V时，处理判定便携设备的兼容电压为9V，当电平值为3V时，判定兼容电压为12V。Further, the charging head is also provided with a voltage detection component, through which the voltage signal on the connection terminal of the positive data line can be detected in real time. When the level value on the positive data line terminal is determined by the voltage detection component. The associated compatible voltage is queried according to the level value. The correlation information between the level signal and the compatible voltage may be pre-stored in a storage medium that can be read by the processor of the charging head. For example, when the level values are 1V, 2V, and 3V, the associated compatible voltages can be 5V, 9V, and 12V, respectively. Therefore, when the processor detects that the level value on the positive data line terminal is 1V through the voltage detection component, it can be determined that the compatible voltage of the portable device currently connected by the USB cable is 5V. When the level value of 2V is 2V, the processing determines that the compatible voltage of the portable device is 9V, and when the level value is 3V, it is determined that the compatible voltage is 12V.
可以理解的是，上述电平值并不用于限定电平值与兼容电压之间的关联特征，仅用于解释本发明提出的充电方法。It can be understood that the above-mentioned level values are not used to define the correlation characteristics between the level values and the compatible voltage, but are only used to explain the charging method proposed by the present invention.
步骤S30、根据所述电平值确定充电电压，并输出所述充电电压。Step S30: Determine the charging voltage according to the level value, and output the charging voltage.
在本实施例中，当确定当前连接的便携设备的兼容电压时，根据兼容电压确定充电头的充电电压，即充电头对便携设备进行充电时的输出电压值。In this embodiment, when the compatible voltage of the currently connected portable device is determined, the charging voltage of the charging head is determined according to the compatible voltage, that is, the output voltage value when the charging head charges the portable device.
具体地，当确定当前连接的便携设备的兼容电压时，线判断充电头的当前输出电压与兼容电压是否匹配。其中，充电头的当前输出电压为预设电压。例如，当输出的预设电压为5V，获取到的便携设备的兼容电压为5V，则判定当前输出电压与兼容电压匹配。当兼容电压与预设电压匹配时，不对充电头的输出电压作调整，即以预设电压作为充电头的充电电压。Specifically, when determining the compatible voltage of the currently connected portable device, the line determines whether the current output voltage of the charging head matches the compatible voltage. Wherein, the current output voltage of the charging head is a preset voltage. For example, when the output preset voltage is 5V and the obtained compatible voltage of the portable device is 5V, it is determined that the current output voltage matches the compatible voltage. When the compatible voltage matches the preset voltage, the output voltage of the charging head is not adjusted, that is, the preset voltage is used as the charging voltage of the charging head.
在预设电压与兼容电压不匹配时，将兼容电压作为充电头的充电电压。即将充电头的输出电压调整为所述兼容电压。例如，预设电压为5V，兼容电压为9V，则将充电头的输出电压从5V，调整为9V。When the preset voltage does not match the compatible voltage, the compatible voltage is used as the charging voltage of the charging head. That is, the output voltage of the charging head is adjusted to the compatible voltage. For example, if the preset voltage is 5V and the compatible voltage is 9V, the output voltage of the charging head is adjusted from 5V to 9V.
在本实施公开的技术方案中，先输出预设电压，然后检测正数据线接线端子的电平值，并根据所述电平值确定便携设备的兼容电压，并根据所述兼容电压确定充电电压，并输出所述充电电压，由于充电头可以通过检测正数据线接线端子的电平值获取当前连接的便携设备的兼容电压，并根据兼容电压确定充电电压，所以在对便携设备进行充电时，用户无需判断充电头是否与便携设备兼容，这样达成了在简化充电步骤的同时，提高充电头的兼容性的效果。In the technical solution disclosed in this implementation, the preset voltage is output first, then the level value of the positive data line terminal is detected, the compatible voltage of the portable device is determined according to the level value, and the charging voltage is determined according to the compatible voltage , and output the charging voltage, because the charging head can obtain the compatible voltage of the currently connected portable device by detecting the level value of the positive data line terminal, and determine the charging voltage according to the compatible voltage, so when charging the portable device, The user does not need to judge whether the charging head is compatible with the portable device, which achieves the effect of improving the compatibility of the charging head while simplifying the charging steps.
在另一实施例中，如图3所示，在上述实施例的基础上，所述步骤S30之后，还包括：In another embodiment, as shown in FIG. 3 , on the basis of the above-mentioned embodiment, after the step S30, the method further includes:
步骤S40、接收所述便携设备反馈的输入电压；Step S40, receiving the input voltage fed back by the portable device;
步骤S50、根据所述输入电压及所述兼容电压确定线损电压；Step S50, determining the line loss voltage according to the input voltage and the compatible voltage;
步骤S60、根据所述线损电压调节所述充电电压。Step S60, adjusting the charging voltage according to the line loss voltage.
在本实施例中，当充电头输出充电电压后，可以接受便携设备反馈的输入电压，即便携设备在充电过程中，充电端口的输入电压。由于充电头与便携设备之间通过USB连接线连接，因此，充电头在的输出端在充电过程中作为电源，而便携设备与USB连接线相当于串联接入电源的负载。当USB连接线的导电性能较差，及/或长度较大时，USB连接线的电阻也会相对较大。从而使得通过USB连接线与电源连接的便携设备的输入电压小于电源电压(充电头的输出电压)。In this embodiment, after the charging head outputs the charging voltage, it can accept the input voltage fed back by the portable device, that is, the input voltage of the charging port during the charging process of the portable device. Since the charging head and the portable device are connected by a USB cable, the output end of the charging head acts as a power source during the charging process, and the portable device and the USB cable are equivalent to a load connected to the power source in series. When the conductivity of the USB connection line is poor and/or the length is large, the resistance of the USB connection line will also be relatively large. Therefore, the input voltage of the portable device connected to the power source through the USB cable is lower than the power source voltage (the output voltage of the charging head).
当充电头接收到便携设备反馈的输入电压时，可以根据所述输入电压与兼容电压判断线损电压。其中，充电头的在充电过程中输出的充电电压与兼容电压相等，因此，输入电压Us、兼容电压Uj与线损电压Ux之间满足一下关系：When the charging head receives the input voltage fed back by the portable device, the line loss voltage can be determined according to the input voltage and the compatible voltage. Among them, the charging voltage output by the charging head during the charging process is equal to the compatible voltage. Therefore, the following relationship is satisfied between the input voltage Us , the compatible voltage Uj and the line loss voltage Ux :
Ux＝Uj-UsUx =Uj -Us
由于输入电压Us、兼容电压Uj与线损电压Ux满足上述关系，且便携设备的兼容电压为已知量。因此，当充电头接收到便携设备反馈的输入电压时，可以根据输入电压及兼容电压确定线损电压。Since the input voltage Us , the compatible voltage Uj and the line loss voltage Ux satisfy the above relationship, and the compatible voltage of the portable device is a known quantity. Therefore, when the charging head receives the input voltage fed back by the portable device, the line loss voltage can be determined according to the input voltage and the compatible voltage.
当确定线损电压后，可以根据所述线损电压调节充电头的充电电压。即将充电头的输出电压提高预设量，以使便携设备的输入电压等于兼容电压。其中，所述预设量可以等于所述线损电压，或者，所述预设量Y可以基于所述线损电压Ux，根据以下公式确定：After the line loss voltage is determined, the charging voltage of the charging head can be adjusted according to the line loss voltage. That is, the output voltage of the charging head is increased by a preset amount, so that the input voltage of the portable device is equal to the compatible voltage. Wherein, the preset amount may be equal to the line loss voltage, or the preset amount Y may be determined based on the line loss voltage Ux according to the following formula:
Y＝αUx+θY=αUx +θ
其中，α与θ分别为调节系数和冗余系数，为固定数值。Among them, α and θ are the adjustment coefficient and the redundancy coefficient respectively, which are fixed values.
可以理解的是，当便携设备可以实时反馈输入电压时，充电头可以根据接收到的实时输入电压确定所述预设量的实时数值，从而根据所述实时预设量对充电电压进行实时调节。这样可以使便携设备的输入电压保持在许可范围内。It can be understood that when the portable device can feed back the input voltage in real time, the charging head can determine the real-time value of the preset amount according to the received real-time input voltage, so as to adjust the charging voltage in real time according to the real-time preset amount. This keeps the input voltage of the portable device within the permissible range.
在本实施例公开的技术方案中，先接收所述便携设备反馈的输入电压，然后根据所述输入电压及所述兼容电压确定线损电压，并根据所述线损电压调节所述充电电压，由于可以确定线损电压并根据线损电压对充电电压进行调节，从而保证了便携设备输入的稳定性，这样达成了在提高充电效率的同时，提高便携设备的充电安全性。In the technical solution disclosed in this embodiment, the input voltage fed back by the portable device is received first, then the line loss voltage is determined according to the input voltage and the compatible voltage, and the charging voltage is adjusted according to the line loss voltage, Since the line loss voltage can be determined and the charging voltage can be adjusted according to the line loss voltage, the stability of the input of the portable device is ensured, thereby improving the charging efficiency of the portable device and improving the charging safety of the portable device.
参照图4，在本法明充电方法的又一实施例中，所述充电方法包括以下步骤：Referring to FIG. 4 , in yet another embodiment of the method for charging the Faming method, the charging method includes the following steps:
步骤S1、在检测到便携设备的USB端口有电压输入时，进行充电端口类型检测；Step S1, when detecting that the USB port of the portable device has voltage input, perform charging port type detection;
步骤S2、在检测到与所述便携设备连接的充电端口的类型为预设类型时，通过所述便携设备的正数据线接线端子输出检测电平，以供充电头根据所述检测电平确定充电电压。Step S2, when it is detected that the type of the charging port connected to the portable device is a preset type, output the detection level through the positive data line terminal of the portable device for the charging head to determine according to the detection level Charging voltage.
在本实施例中，以执行主体为是便携设备，例如，手机，平板电脑等进解释说明。In this embodiment, the execution subject is a portable device, such as a mobile phone, a tablet computer, etc., for explanation.
所述便携设备设置有充电端口，其中，所述充电端口可以是USB端口。在USB端口检测到电压输入时，便携设备可以进行充电端口的类型检测。由于USB端口可以在不同的应用场景中设置为不同的端口类型，例如，可以设置为标准下行端口(SDP，StandardDownstream Port)、专用充电端口(DCP，Dedicated Charging Port)或者充电下行端口(CDP，Charging Downstream Port)。The portable device is provided with a charging port, wherein the charging port may be a USB port. When the USB port detects a voltage input, the portable device can perform type detection of the charging port. Since the USB port can be set to different port types in different application scenarios, for example, it can be set to a standard downstream port (SDP, StandardDownstream Port), a dedicated charging port (DCP, Dedicated Charging Port) or a charging downstream port (CDP, Charging). Downstream Port).
因此当检测到USB电压输入时，可以进行端口类型检测。So when USB voltage input is detected, port type detection can be done.
具体地，可以先检测当前输入电压对应的接入电流是否为有效电路，及判定当前输入电压是否在大于判定电压值。其中，所述判定电压值为一预设数值，例如可以设置在0.8V-4V之间。Specifically, it is possible to first detect whether the access current corresponding to the current input voltage is a valid circuit, and determine whether the current input voltage is greater than the determined voltage value. Wherein, the determination voltage value is a preset value, for example, can be set between 0.8V-4V.
接入电路为有效电路时，可以进行数据连接检测(Detect Vbus)，即判定在预设时长内是检测到DP或者ID PIN(ID personal identification number，身份别针)连接，当检测到数据连接时，判定为SDP。当端口不是SDP时，则区分端口CDP和DCP。When the access circuit is an effective circuit, data connection detection (Detect Vbus) can be performed, that is, it is determined that a DP or ID PIN (ID personal identification number, identity pin) connection is detected within a preset time period. When a data connection is detected, Judged as SDP. When the port is not SDP, the port CDP and DCP are distinguished.
可选地，可以先进行Primary Detection(首次检测)，其中，Primary Detection用于确认充电口是否支持数据协议。进行Primary Detection时，先将DP拉高值预设电平值，例如，可以是0.6V，然后检测DM上的电平值。如果DM上的电平值小于规定的参考电压，则端口是SDP，否则为CDP或者DCP。可以理解的是，也可以直接跳过Primary Detection，直接进行Secondary Detection。Optionally, Primary Detection (first detection) may be performed first, where Primary Detection is used to confirm whether the charging port supports the data protocol. When performing Primary Detection, first pull up the DP to a high value to preset the level value, for example, it can be 0.6V, and then detect the level value on the DM. If the level value on the DM is less than the specified reference voltage, the port is SDP, otherwise it is CDP or DCP. It is understandable that Primary Detection can also be skipped directly and Secondary Detection can be performed directly.
具体地，Secondary Detection阶段用于区分CDP和DCP。在进行SecondaryDetection时，线将DM拉高至拉高至0.6V，然后检测DP的电压值，如果小于规定的参考电压，则端口时CDP，否则为DCP。Specifically, the Secondary Detection stage is used to distinguish between CDP and DCP. During SecondaryDetection, the line pulls up DM to 0.6V, and then detects the voltage value of DP. If it is less than the specified reference voltage, the port is CDP, otherwise it is DCP.
当确定端口类型为DCP时，便携设备可以通过正数据线向充电头输出检测电平。其中，检测电平的具体数值根据便携设备自身的兼容电压确定。When it is determined that the port type is DCP, the portable device can output the detection level to the charging head through the positive data line. The specific value of the detection level is determined according to the compatible voltage of the portable device itself.
具体地，当确定端口为DCP时，便携设备根据自身的兼容电压确定检测电平的具体数值。其中，兼容电压与检测电平的具体数值之间设置有关联关系。例如，当兼容电压为5V时，关联的检测电平的具体数值可以是1V。因此，便携设备可以根据兼容电压确定检测电平的具体数值。Specifically, when it is determined that the port is a DCP, the portable device determines a specific value of the detection level according to its own compatible voltage. Wherein, a correlation relationship is set between the compatible voltage and the specific value of the detection level. For example, when the compatible voltage is 5V, the specific value of the associated detection level may be 1V. Therefore, the portable device can determine the specific value of the detection level according to the compatible voltage.
当确定检测电平的具体数值时，便携设备将DP上的电平值拉高至所述具体数值，以供充电头检测到DP的电平值时，根据DP上的电平值确定便携设备的兼容电压。When the specific value of the detection level is determined, the portable device pulls up the level value on the DP to the specific value, so that when the charging head detects the level value of the DP, the portable device is determined according to the level value on the DP compatible voltage.
在本实施例公开的技术方案中，在检测到USB输入电压时，进行充电端口类型检测，然后在检测到充电端口类型为预设类型时，通过正数据线输出检测电平，以供充电头根据所述检测电平获取便携设备的兼容电压，由于充电头可以根据正数据线上的电平值确定便携设备的兼容电压，因此充电头可以根据兼容电压确定充电电压，从而使得在充电过程中，充电头可以适配便携设备，这样达成了简化充电步骤的效果。In the technical solution disclosed in this embodiment, when the USB input voltage is detected, the type of the charging port is detected, and then when it is detected that the type of the charging port is a preset type, the detection level is output through the positive data line for the charging head Obtain the compatible voltage of the portable device according to the detection level. Since the charging head can determine the compatible voltage of the portable device according to the level value on the positive data line, the charging head can determine the charging voltage according to the compatible voltage, so that during the charging process , the charging head can be adapted to portable devices, thus achieving the effect of simplifying the charging steps.
