在一些实施例中，充电策略模块234比对第一充电电路和第二充电电路同时充电的功率值和第一充电电路和第二充电电路单独充电的充电功率值，协商使用功率值最大的充电电路进行充电。

步骤S611：检测所述第一接口模块40、第二接口模块50和无线充电芯片60接入外部充电器的类型。
本实施例中，所述接口检测模块231依次检测所述第一接口模块40、第二接口模块50和无线充电芯片60是否接入外部充电器，并检测接入外部充电器的类型。本实施例中，所述接口检测模块231结合USB协议芯片90通过所述第一接口模块40和第二接口模块50的数据传输线D+/D-使用BC1.2电池充电协议(battery charging specification 1.2)检测接入的外部充电器的类型。本实施例中，检测接入的外部充电器类型包括与SDP、CDP、DCP、FCP、SCP等匹配的充电器。可以理解，不同类型的充电器具有不同的充电能力，提供不同的充电电压及充电电流。
步骤S612：建立各接口接入充电器的充电能力数据集。
可选的，本实施例中，所述充电策略模块234根据接口检测模块231识别的接入的外部充电器的类型并整理这些外部充电器所支持的充电能力数据，建立充电能力数据集，例如充电能力列表或其他数据集的形式。例如，所述第一接口模块40接入的外部充电器建立充电能力列表：V_t1/I_t1、V_t2/I_t2、V_t3/I_t3、……、V_tn/I_tn。其中，n为正整数，V_tn为充电电压，I_tn为充电电流。所述第二接口模块50接入的外部充电器建立充电能力列表：V_p1/I_p1、V_p2/I_p2、V_p3/I_p3、……、V_pn/I_pn。其中，n为正整数，V_pn为充电电压，I_pn为充电电流。所述无线充电芯片60接入的外部无线充电器建立充电能力列表：V_w1/I_w1、V_w2/I_w2、
V_w3/I_w3、……、V_wn/I_wn。其中，n为正整数，V_wn为充电电压，I_wn为充电电流。例如，所述第一接口模块40接入的外部充电器支持的输出充电电压/电流为5v/2A，10v/4A，则其对应的充电能力值为V_t1＝5v，I_t1＝2A， V_t2＝10v，I_t2＝4A。则第一接口模块40接入的外部充电器的充电能力列表可以如表1所示：
  输出充电电压(V) 输出充电电流(I)
第一充电能力项 5V 2A
第二充电能力项 10V 4A
…第n充电能力项 xV yA
表1
步骤S613：查询是否存在充电电压相等的情况。
本实施例中，所述充电策略模块234依次遍历所述第一接口模块40、第二接口模块50和无线充电芯片60所接入的充电器的充电能力列表查询是否存在充电电压相等的情况。当所述第一接口模块40、第二接口模块50和无线充电芯片60均接入外部充电器，且存在V_tx、V_wx、V_px中任意两组或两组以上相等的情况，其中，x为正整数，也即V_tx＝V_wx＝V_px、V_tx＝V_wx、V_tx＝V_px或V_wx＝V_px，则执行步骤S614；否则，执行步骤S615。
步骤S614：计算多线路同时充电时的充电理论功率值。
本实施例中，所述电池监控模块233获取所述充电芯片20和电池30支持最大充电电流I_max。当查询到存在V_tx＝V_wx＝V_px＝V1时，计算三路同时充电(即同时使用第一接口模块40、第二接口模块50和无线充电芯片60接入外部充电器充电)的充电理论功率值Px＝V1*MIN(I_max,(I_tx+I_wx+I_px))。当查询到存在V_tx＝V_wx＝V2时，计算两路同时充电(即同时使用第一接口模块40和无线充电芯片60接入外部充电器充电)的充电理论功率值Px＝V2*min(I_max,(I_tx+I_wx))。其他两路同时充电的充电理论功率值的计算同理，在此不再累述。例如，充电芯片20和电池30支持最大充电电流I_max＝7A，当查询到存在V_tx＝V_wx＝V_px＝V1＝5V时，对应的输出充电电流分别为I_tx＝2A，I_wx＝2.4A，I_px＝2.5A，计算三路同时充电的充电理论功率值Px＝V1*MIN(I_max,(I_tx+I_wx+I_px))＝5V*MIN(7A，2A+2.4A+2.5A))＝34.5W。
在一些实施例中，当多路充电的电流值超过充电芯片20和电池30支持最大充电电流I_max，则通过MIN函数取较小的最大充电电流I_max进行计算，因此计算的充电理论功率值Px不会超过充电芯片20和电池30支持最大充电电流I_max，使得充电时的充电电流不会超过最大充电电流I_max，可保证充电安全，有效保护充电芯片20和电池30。
在一些实施例中，在步骤S614之后执行步骤S615。
步骤S615：计算各线路单独充电时的充电最大功率值。
本实施例中，计算单一线路充电时的充电最大功率值，例如，所述第一接口模块40接入的外部充电器的充电最大功率值Pt_max取V_tx*I_tx的 最大值；所述第二接口模块50接入的外部充电器的充电最大功率值Pw_max取V_wx*I_wx的最大值；所述无线充电芯片60接入的外部充电器的充电最大功率值Pp_max取V_px*I_px的最大值。可以理解，所有组合方式的充电最大功率值均小于充电芯片20和电池30支持的最大充电功率，可保证充电安全，有效保护充电芯片20和电池30。
步骤S616：协商使用最大充电功率进行充电。
本实施例中，所述充电策略模块234比对多线路同时充电的功率值和多组单一线路的充电最大功率值，协商使用功率最大值最大的充电线路同时充电。例如，比对多路(三路或两路)同时充电的充电理论功率值Px和多组单一线路的充电最大功率值Pt_max、Pw_max和Pp_max的大小，选取其中最大的充电功率值，协商使用所述最大的充电功率值对应的充电线路进行充电。当查询到存在V_tx＝V_wx＝V_px＝V1，且比对多路同时充电的充电理论功率值Px为最大值时，则协商使用三路同时充电；例如，当多路同时充电的充电理论功率值Px为34.5W，第一接口模块40接入的外部充电器的充电最大功率值Pt_max为30.8W，第二接口模块50接入的外部充电器的充电最大功率值Pw_max为31.2W，无线充电芯片60接入的外部充电器的充电最大功率值Pp_max为33.4W，其中，比对多路同时充电的充电理论功率值Px为最大值，则协商使用三路同时充电。当查询到存在V_tx＝V_wx＝V2，且比对多路同时充电的充电理论功率值Px为最大值时，则协商使用两路同时充电；当单一线路的充电最大功率值Pt_max为最大值时，则协商使用Pt_max对应的充电线路进行单一线路充电。其他线路组合同理。
可以理解，由于多路同时充电的充电电流不超过所述充电芯片20和电池30支持最大充电电流I_max，因此多路同时充电的充电理论功率值Px为所述充电芯片20和电池30的安全充电范围内，即提高了充电效率也保证了充电芯片20和电池30的使用安全。
步骤S617：控制所述多个开关模块92、94、96的通断以实现充电线路的接通。
本实施例中，所述充电驱动模块235根据协商使用的充电线路控制对应充电线路上的开关模块92、94、96中的部分或全部模块接通，未使用的充电线路对应的开关模块92、94、96中的部分或全部模块截止。例如，当V_tx＝V_wx＝V_px＝V1时，协商使用三路同时充电，所述充电驱动模块235控制开关模块92、94、96接通，则所述第一接口模块40、第二接口模块50及无线充电芯片60接入的外部充电器同时输出充电电压及电流通过充电芯片20为电池30充电。当V_tx＝V_wx＝V2时，协商使用两路同时充电，所述充电驱动模块235控制开关模块92、96接通，控制开关模块94截止，则所述第一接口模块40及无线充电芯片60接入的外部充电器同时输出充电电压及电流通过充电芯片20为电池30充电。当协商使用Pt_max对应的充电线路进行单一线路充电，所述充电驱动模块235控制开关模块92接通，控制开关模块94、96截止，则所述第一接口模块40接入的外部充电器输出充电电压 及电流通过充电芯片20为电池30充电。
本实施例中，所述库仑计模块232提供查询所述电池30的状态信息，例如电池温度、电量、电流、电压等，当充电过程中监测到实时充电电流超过电池支持的最大充电电流I_max，则提供反馈给所述充电策略模块234，以通过所述充电驱动模块235控制所述充电线路的切断，以保护电池。
