下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
参见图1，图1是本公开实施例提供的充电控制电路的结构图，如图1所示，包括第一充电子电路1和第二充电子电路2，所述第一充电子电路1的充电效率大于所述第二充电子电路2的充电效率，所述充电控制电路还包括切换电路3；所述切换电路3的第一触点与充电接口4连接，所述切换电路3的第二触点与无线充电模块5的输出端连接，所述切换电路3的第三触点与所述第一充电子电路1的输入端连接；在无线充电的情况下，所述第一触点与所述第三触点之间断开，所述第二触点与所述第三触点之间导通。
本实施例中，上述第一充电子电路1可以为快速充电通路，上述第二充电子电路2可以为充电电源管理集成电路(Power Management IC，PMIC)。由于在无线充电的情况下，所述第一触点与所述第三触点之间断开，所述第二触点与所述第三触点之间导通，那么在无线充电的过程中，共用终端设备充电效率较高的第一充电子电路1，从而可以提高终端设备的无线充电效率。
本实施例中，在使用第一充电子电路1进行无线充电的过程中，无线充电模块5可以输出高电压，从而使终端设备在无线充电时整个充电系统损耗更低，能提高终端设备的充电速度和降低充电温升，使用户有更好的体验。并且，当有线充电器接入时，充电方式可以自动切换为有线充电，满足更快充电速度。
请再参阅图2，图2为本公开实施例提供的充电系统功能框图。图2中，有线充电通路(恒流充电)依次包括：充电接口、切换电路、快充充电通路和电池。有线充电通路(涓流、恒压充电、充电终止)依次包括：充电接口、 充电PMIC和电池。无线充电通路(恒流充电)依次包括：电感电容、无线充电模块、切换电路、快充充电通路和电池。无线充电通路(涓流、恒压充电、充电终止)依次包括：电感电容、无线充电模块、充电PMIC和电池。

该实施方式中，上述第一控制端可以是切换电路3内部的一个控制端，或者也可以是切换电路3外部的一个控制端，对此本实施方式不作限定。由于所述第一子电路包括第一NMOS管和第二NMOS管，并且所述第一NMOS管的栅极和所述第二NMOS管的栅极均连接至第一控制端，那么只需要一个信号就可以同时控制第一NMOS管和第二NMOS管的断开或者导通，使电路的控制更加简单。
例如，当第一控制端发送第一信号时，第一NMOS管和第二NMOS管可以导通；当第一控制端发送第二信号时，第一NMOS管和第二NMOS管可以断开，从而便于进行控制。在无线充电的情况下，第一控制端发送第二信号，第一NMOS管和第二NMOS管均断开，不会对第二子电路造成影响。并且可以导通第二子电路，使用充电效率较大的第一充电子电路进行充电，提高终端设备的无线充电的效率。

例如，当第二控制端发送第三信号时，第三NMOS管和第四NMOS管可以导通；当第二控制端发送第四信号时，第三NMOS管和第四NMOS管可以断开，从而便于进行控制。在无线充电的情况下，第二控制端发送第三信号，第三NMOS管和第四NMOS管均导通，使用充电效率较大的第一充电子电路进行充电，提高终端设备的无线充电的效率。并且此时可以断开第一子电路，避免第一子电路对第二子电路造成影响。
为了更好的理解第一子电路、第二子电路以及整个充电控制电路的结构，可以参阅图3和图4，图3和图4均为本公开实施例提供的充电控制电路的结构图。
首先可以如图3所示，第一充电子电路1为充电PMIC，第二充电子电路2为快充充电通路。无线充电模块5：集成整流器模块电路，接受发射端传送的交流电力信号，并将交流电力信号整流为直流电力输出电压VINB作为充电芯片(充电PMIC和快充充电通路)的输入电压；集成双通信模块电路：幅移键控(Amplitude Shift Keying,ASK)通信模块和频移键控(Frequency Shift Keying,FSK)通信模块，ASK通信模块负责将接收端的通信信号调制到载波信号中，发送到发射端设备，FSK通信模块负责接收发射端发送的通信信号，并解调通信信号后，与系统完成通信；集成保护机制模块电路(过压、温度)等。
切换电路3：给充电提供一种低阻抗通路。默认使用VINB通路，当充电器接入充电接口时自动切换到VINA通路。
快充充电通路所示为一种半压电路原理示意图，半压器件内部通常单个模块采用4个NMOS管做开关如图中Q1、Q3、Q2和Q4，电容Cfly与Cout形成并联。输入端电压为Vbus，输出端电池电压为VBAT，电容Cfly两端电压为Vcfly。在整个电路工作中，通过控制开关管的状态对电容Cfly进行充电和放电，控制开关占空比为50％，实现Vout＝Vin/2，从而实现电压减半，电流增倍的功能。
充电PMIC为高效率充电IC，实现对电池的充电参数控制和管理。VBAT为单节锂离子或锂聚合物电池组。
再参阅图4，第一充电子电路1为充电PMIC，第二充电子电路2为快充充电通路。图4与图3存在以下差异，快充充电通路所示为直充等效电路原理示意图，使用的直充开关一般由两个分立N mosfet或者集成IC(与分立N mosfet类似)实现。开关导通时直接由充电器对电池VBAT充电。

在无线充电且请求成功的情况下，控制所述切换电路的第一触点与第三触点之间断开，第二触点与第三触点之间导通。
该实施方式中，上述充电器为无线充电器，上述高压充电请求中可以包含需要的高压范围。在无线充电且请求成功的情况下，控制所述切换电路的第一触点与第三触点之间断开，第二触点与第三触点之间导通。请求成功则表示无线充电器可以提供高压，其次可使用充电效率较大的第一充电子电路进行充电，提高了终端设备的无线充电的效率。
可选地，在所述向充电器发送高压充电请求之后，所述方法还包括：
在无线充电且请求失败的情况下，通过第二充电子电路进行无线充电。
该实施方式中，在无线充电且请求失败的情况下，通过第二充电子电路进行无线充电。此时可以是无线充电器不能输出请求范围的高压，那么可以使用充电PMIC进行充电。
可选地，所述在无线充电的情况下，控制切换电路的第一触点与第三触 点之间断开，第二触点与第三触点之间导通之后，所述方法还包括：

该实施方式中，在有线充电器接入的情况下，控制切换电路的第一触点与第三触点之间导通，第二触点与第三触点之间断开。充电方式自动切换为有线充电，可以有更快充电速度以及减小充电温升。
需要说明的是，上述实施方式可以单独实现，也可以结合实现，对此本公开实施例不作限定。例如，终端设备与无线充电座握手不成功，不充电。当终端与无线充电座握手成功，此时符合快充充电条件(电池的恒流充电阶段，如电池电压Vbat大于预设值V1或温度T小于预设值t1等)，则无线充电请求充电器高压模式。充电器输出高压后，然后终端设备使用快充充电通路充电。不符合快充充电条件(电池的涓流充电、恒压充电阶段等)，则使用充电PMIC通路充电充电器不能输出请求范围的高压，则使用充电PMIC通路充电。
本公开实施例的一种控制方法，在无线充电的情况下，控制切换电路的第一触点与第三触点之间断开，第二触点与第三触点之间导通。这样，在无线充电的情况下，可使用充电效率较大的第一充电子电路进行充电，提高了终端设备的无线充电的效率。

处理器610是终端设备的控制中心，利用各种接口和线路连接整个终端设备的各个部分，通过运行或执行存储在存储器609内的软件程序和/或模块，以及调用存储在存储器609内的数据，执行终端设备的各种功能和处理数据，从而对终端设备进行整体监控。处理器610可包括一个或多个处理单元；优选的，处理器610可集成应用处理器和调制解调处理器，其中，应用处理器 主要处理操作系统、用户界面和应用程序等，调制解调处理器主要处理无线通信。可以理解的是，上述调制解调处理器也可以不集成到处理器610中。
终端设备600还可以包括给各个部件供电的电源611(比如电池)，优选的，电源611可以通过电源管理系统与处理器610逻辑相连，从而通过电源管理系统实现管理充电、放电、以及功耗管理等功能。
另外，终端设备600包括一些未示出的功能模块，在此不再赘述。
优选的，本公开实施例还提供一种终端设备，包括处理器610，存储器609，存储在存储器609上并可在所述处理器610上运行的计算机程序，该计算机程序被处理器610执行时实现上述控制方法实施例的各个过程，且能达到相同的技术效果，为避免重复，这里不再赘述。
本公开实施例还提供一种计算机可读存储介质，计算机可读存储介质上存储有计算机程序，该计算机程序被处理器执行时实现上述控制方法实施例的各个过程，且能达到相同的技术效果，为避免重复，这里不再赘述。其中，所述的计算机可读存储介质，如只读存储器(Read-Only Memory，ROM)、随机存取存储器(Random Access Memory，RAM)、磁碟或者光盘等。
需要说明的是，在本文中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者装置不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到上述实施例方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本公开的技术方案本质上或者说对相关技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端(可以是手机，计算机，服务器，空调器，或者网络设备等)执行本公开各个实施例所述的方法。
