下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清除、完整地描述，显然，所描述的实施例仅仅是本发明的一部分实施例，而不是全部的实施例。
基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都属于本发明保护的范围。
参考图1所示，是本发明较佳实施例的电子装置100的电路图。所述电子装置100包括充电模块10及CPU(Central Processing Unit，中央处理器)30。所述电子装置100可与充电器200相连，以进行充电。所述充电器200包括连接器201。所述连接器201可以是USB连接器，所述连接器201包括电压引脚VBUS、接地引脚GND、数据引脚USB_D+(D+)及USB_D-(D-)。
所述充电模块10设置为与充电器200相连，所述充电模块10与VBUS引脚、接地引脚GND直接相连，经第一电阻R1与数据引脚USB_D+相连，以及经第二电阻R2与数据引脚USB_D-相连。
所述CPU30与所述充电模块10相连，设置为控制所述充电模块10检测所连接的所述充电器200的端口类型，并根据所述充电器200的端口类型，控制所述充电器200对电子装置100的充电方案。具体的，CPU30从所述充电器200获取与所述端口类型对应的充电电流，以对所述电子装置100进行充电。
在本较佳实施例中，所述充电器200的端口类型包括SDP(Standard Downstream Port，标准下行端口)、CDP(Charging Downstream Port，充电下行端口)以及DCP(Dedicated Charging Port，专用充电端口)。如果所述充电模块10检测到所述充电器200为SDP类型，则从所述充电器200获取第一充电电流对所述电子装置进行充电，如果所述充电模块10检测到所述充电器200为CDP类型，则从所述充电器200获取第二充电电流对所述电子装置进行充电。在本较佳实施例中，所述第一充电电流为最大电流约为500mA的充电电流，所述第二充电电流为最大电流约为900mA的充电电流。
如果所述充电模块10检测到所述充电器200为DCP类型的充电器，所 述CPU 30控制所述充电模块10进一步检测所述充电器200是否支持专用快充协议，如果所述充电器200支持专用快充协议，则选择对应的专用快充协议方案对所述电子装置100进行充电。
在本较佳实施例中，所述专用快充协议包括Quick Charge 2.0协议(QC2.0)、Quick Charge 3.0协议(QC3.0)、Pump Express 2.0快充协议，(简称PE+2.0)，Pump Express 3.0快充协议、VOOC(Voltage Open Loop Multi-step Constant-Current Charging，电压开环多步恒流充电)协议。所述CPU 30具体检测所述充电器200所支持的专用快充协议在如图2-图7中所示的本发明的较佳实施方式中具体详述。
在本发明的另一较佳实施例中，所述电子装置100还包括电源管理模块70，所述电源管理模块70设置为检测所述电子装置100是否与所述充电器200相连，如果所述充电模块10与所述充电器200相连，则所述充电模块10检测所述充电器200的端口类型，如果所述充电模块10未与所述充电器200相连，则所述电源管理模块70则以预设频率重复检测，直至检测到所述充电器200与所述电子装置100相连。
参考图2所示，本发明充电方法第一较佳实施方式的流程图。所述充电方法包括以下步骤。所述较佳实施方式也是本发明的较佳实施例。根据不同的需求，该图所示流程图中的执行顺序可以改变，某些可以省略。
步骤300，所述电源管理模块70检测所述充电模块10是否与所述充电器200相连，如果检测到所述电子装置100与充电器200相连，则进入步骤301，如果未检测到所述电子装置100与充电器200相连，则重复所述步骤。
步骤301，所述CPU 30控制所述充电模块10检测USB电池充电规范1.2协议(简称BC 1.2)，以完成电子装置100与充电器200的第一次握手。
步骤302，所述CPU 30控制所述充电模块10检测所连接的充电器200是否是SDP类型的充电器200，如果检测到所连接的充电器200是SDP类型的充电器，则进入步骤303，如果检测到所连接的充电器200不是SDP类型的充电器，则进入步骤304。
在本发明的一个实施例中，当电子装置100连接到充电器200后，若充 电模块10检测到电子装置的D+、D-信号为低电平时，则确定所接的设备为SDP类型充电器。
步骤303，所述CPU 30控制所述充电模块10从充电器200获取第一充电电流对所述电子装置100进行充电。在本较佳实施例中，所述第一充电电流为最大电流约为500mA的充电电流。
步骤304，所述CPU 30控制所述充电模块10检测所连接的充电器200是否是CDP类型的充电器200，如果检测到所连接的充电器200是CDP类型的充电器，则进入步骤305，如果检测到所连接的充电器200不是CDP类型的充电器，则进入步骤306。
在本发明的一个实施例中，当电子装置100连接到一个充电器时，然后打开电子装置100的D-信号的上拉电源VDM_SRC，即电子装置100的D-信号为高电平，断开电子装置100的D+信号的上拉电源VDP_SRC，打开电子装置100的D+信号的下拉电流源IDP_SINK，此时电子装置100的D+信号将变成低电平，则可据此判断所连接的充电器为CDP类型的充电器。
步骤305，所述CPU 30控制所述充电模块10从充电器200获取第二充电电流对所述电子装置100进行充电。在本较佳实施例中，所述第二充电电流为最大电流约为900mA的充电电流。
步骤306，所述CPU 30控制所述充电模块10检测所连接的充电器200是否是DCP类型的充电器，如果检测到所连接的充电器200是DCP类型的充电器200，则进入步骤307，如果检测到所连接的充电器200不是DCP类型的充电器，则进入步骤308。
在本发明的一个实施例中，当电子装置100连接到一个充电器时，然后打开电子装置100的D-信号的上拉电源VDM_SRC，即电子装置100的D-信号为高电平，断开电子装置100的D+信号的上拉电源VDP_SRC，打开电子装置100的D+信号的下拉电流源IDP_SINK，此时电子装置100的D+信号将变成高电平，此时，据此判断所连接的充电器为DCP类型的充电器。
步骤307，所述CPU 30控制所述充电模块10设定从充电器200获取第三充电电流对所述电子装置100进行充电。在本较佳实施例中，所述第三充 电电流为最大电流约为500mA的充电电流。
步骤308，所述CPU 30控制所述充电模块10检测所述充电器200是否支持QC3.0协议，如果所述充电器200支持QC3.0协议，则进入步骤309，如果所述充电器200不支持QC3.0协议，则进入步骤310。
在本发明的一个实施例中，类似于QC2.0协议的检测，电子装置100先根据USB BC1.2规范执行检测，再根据D+上的输出电压检测所述充电器200是否支持QC3.0协议。具体检测的方法可以参照QC3.0协议的内容。
步骤309，所述CPU 30控制所述充电模块10采用QC3.0协议方案对所述电子装置100进行充电。
步骤310，所述CPU 30控制所述充电模块10检测所述充电器200是否支持QC2.0协议，如果所述充电器200支持QC2.0协议，则进入步骤311，如果所述充电器200不支持QC2.0协议，则进入步骤312。
在本发明的一个实施例中，电子装置100根据USB BC1.2规范执行检测，当检测到DCP类型的充电器200时，电子装置100在其D+打开一个上拉电源VDP_SRC。充电器200检测D+上的输出电压、并确保D+上的输出电压在一秒的时长里高于第一判断电平VDAT_REF并低于第二判断电平VSEL_REF。一秒以后，充电器200将D+和D-开路并接通下拉电阻Rdm_dwn。如果D-保持为低，那么电子装置100不支持QC2.0协议规范。如果D-保持为高，则电子装置100支持QC2.0协议。
步骤311，所述CPU 30控制所述充电模块10采用QC2.0协议方案对所述电子装置100进行充电。
步骤312，所述CPU 30控制所述充电模块10检测所述充电器200是否支持PE+3.0协议，如果所述充电器200支持PE+3.0协议，则进入步骤313，如果所述充电器200不支持PE+3.0协议，则进入步骤314。
在本发明的一个实施例中，当充电模块10确定与电子装置100相连的充电器为CDP类型或者DCP类型时，充电模块10根据PE+3.0协议中的握手协议判断充电器200是否支持PE+3.0协议。例如充电模块10发送升电压指令Current Pattern，充电器200的输出电压调整至一个预设值并维持。因此， 充电模块10透过量测VBUS可以判定经由USB连接器插入的装置是否为符合FC协议的电源适配器。若VBUS符合电源适配器输出所述预设值的规格，可以判定为充电器200支持PE+3.0协议。
步骤313，所述CPU 30控制所述充电模块10采用PE+3.0协议方案对所述电子装置100进行充电。
步骤314，所述CPU 30控制所述充电模块10检测所述充电器200是否支持PE+2.0协议，如果所述充电器200支持PE+2.0协议，则进入步骤313，如果所述充电器200不支持PE+2.0协议，则进入步骤314。
在本发明的一个实施例中，当充电模块10确定与电子装置100相连的充电器为CDP类型或者DCP类型时，充电模块10发送升电压指令Current Pattern，目的是进一步区别插入的装置是否为符合PE+2.0协议的电源适配器。
充电器200的输出电压调整至7V并维持。因此，充电模块10透过量测VBUS可以判定经由USB连接器插入的装置是否为符合FC协议的电源适配器。若VBUS符合电源适配器输出7V的规格，可以判定为充电器200支持PE+2.0协议。
步骤315，所述CPU 30控制所述充电模块10采用PE+2.0协议方案对所述电子装置100进行充电。
步骤316，所述CPU 30检测所述充电器200是否支持VOOC协议，如果所述充电器200支持VOOC协议，则进入步骤315，如果所述充电器200不支持QC2.0协议，则进入步骤316。
在本发明的一个实施例中,充电模块10通过检测连接器201的D+信号，及D-信号来判断VOOC的协议，其中D+用于传输握手信号的CLK数据，D-用于传输握手信号的DATA数据。
步骤317，所述CPU 30采用VOOC协议方案对所述电子装置100进行充电。
步骤318，所述CPU 30控制所述充电模块10按照普通5V充电器类型进行常规充电。
