再例如，在该充电系统中，电源适配器与充电线缆也可以一体地设置，此情况下，充电接口可以仅包括上述接口#C和接口#D。
因此，在本发明实施了中，在S110，电源适配器可以确定以上接口#A～接口#D中至少一个接口的温度，下面，分别对各接口的温度的确定过程进行详细说明。
1.确定接口#A的温度的过程
可选地，当该充电接口包括该电源适配器的用于与该充电线缆进行电连接的接口时，该确定充电接口的温度包括：
通过设置在电源适配器的接口中的第一测温元件，确定该充电接口的温度。
具体地说，在本发明实施了中，可以在电源适配器中设置用于检测该接 口#A的温度的测温元件(即，第一测温元件的一例，以下，为了便于理解和区分，记做：测温元件#A)。
从而，该电源适配器可以通过测温元件#A检测接口#A的温度。
可选地，该通过设置在电源适配器的接口中的第一测温元件，确定该充电接口的温度，包括：
通过设置在电源适配器的接口中的至少一个第一测温元件，检测该电源适配器的接口中的至少一个接触片的温度，该至少一个第一测温元件与该至少一个接触片一一对应，该接触片用于传输充电电流；
根据该至少一个接触片的温度，确定该充电接口的温度。
具体地说，图2示出了测温元件与电子接口的配置关系的一例的示意图，如图2所示，接口#A中(例如，接口#A的插舌上)可以配置有多个金属制的接触片，并且，尽管未图示，但是在接口#B中(例如，接口#B的插舌上)也可以配置有多个金属制的接触片，并且，通常情况下，接口#A中的多个接触片与接口#B中的多个接触片之间一一对应(例如，位置相对应)，从而，当接口#A与接口#B连接时，接口#A中的每个接触片与接口#B中所对应的接触片接触，从而实现电源适配器与充电线缆的电连接。
由于接触片是发热源，因此，在本发明实施例中，可以通过测温元件#A检测接口#A中的接触片的温度，并根据接口#A中的接触片的温度确定接口#A的温度。
在本发明实施了中，例如，可以根据接口#A的配置空间等而选用不同形式的温度传感器作为该测温元件#A，例如，可以选用热敏电阻作为该测温元件#A。
在本发明实施了中，该测温元件#A的数量可以为一个也可以为多个，本发明并未特别限定，其中，为了确保测量的准确性，一个测温元件#A仅与接触片相对应，或者说，一个测温元件#A仅用于测量一个接触片的温度。
可选地，该电源适配器配的接口中配置有至少两个测温元件，该至少两个测温元件与该电源适配器配的接口中的至少两个接触片一一对应。
具体地说，在本发明实施例中，可以根据接口#A的接触片的数量确定所配置的测温元件#A的数量，例如，使接口#A的接触片的数量与测温元件#A的数量相等，从而，能够通过各测温元件分别测量到其所对应的接触片的温度，获知接口#A中所有接触片的温度。
例如，如图2所示，当接口#A中用于传输电流的接触片为两个(以下，为了便于理解和区分，记做：接触片#A1和接触片#A2)时，可以配置两个测温元件(以下，为了便于理解和区分，记做：测温元件#A1和测温元件#A2)，其中，测温元件#A1与接触片#A1相对应，用于测量接触片#A1的温度，测温元件#A2与接触片#A2相对应，用于测量接触片#A2的温度。
下面，对该测温元件#A与接口#A的接触片的配置关系进行详细说明。
在本发明实施了中，当配置多个测温元件#A时，各测温元件#A与所对应的接触片的配置方式可以相同或相似，为了避免赘述，以下，以图2中测温元件#A1与接触片#A1的配置为例，进行说明。
例如，可选地，在本发明实施了中，测温元件#A1可以直接贴合配置在接触片#A1的表面。
再例如，可选地，在本发明实施了中，每个第一测温元件与所对应的接触片设置在同一导热基板上，每个第一测温元件与所对应的接触片之间具有预设间隔。
具体地说，如图2所示，测温元件#A1与接触片#A1可以设置在同一导热基板上，从而，该接触片#A1的热量能够通过该导热基板而传递至测温元件#A1，并且，该接触片#A1与测温元件#A1之间隔有预设的间隔α，并且，例如，该间隔α的大小可以根据接口A的尺寸和配置来调整。通过设置间隔α能够避免因直接接触而导致流经接触片#A1的电流对测温元件#A1的影响。
可选地，该导热基板为金属制。
具体地说，在本发明实施例中，为了提高导热基板的导热性能，优选使用金属材料作为导热基板，并且，可以使该导热基板的厚度尽可能小，从而能够进一步提高导热性。例如，可以使用铜箔作为该导热基板。
可选地，在该第一测温元件与该导热基板之间设置有绝缘导热层；或
在该第一测温元件所对应的接触片与该导热基板之间设置有绝缘导热层。
具体地说，由于对电子设备进行充电时，电流均需流经接口#A的接触片#A1，因此，在使用金属制导热基板时，存在电流从接触片#A1经由导热基板而传输至测温元件#A1的情况，在使用例如热敏电阻或电子温度传感器等电子元件作为测温元件#A1时，从接触片#A1经由导热基板而流入的电流 可能会对测温元件#A1造成影响。通过在测温元件#A1与导热基板之间设置绝缘层，或者，在接触片#A1与导热基板之间设置绝缘层，能够在传导热量的同时有效避免测温元件#A1受到外来电流的影响，提高本发明的电池组件的安全性和可靠性。
应理解，以上列举的导热基板的材料和外形仅为示例性说明，本发明并不限定于此，只要能够使热量由接触片传递至测温元件即可，例如，也可以使用表面铺设有导热层的印制电路板(PCB，Printed Circuit Board)作为导热基板。

通过该第一测温元件在至少两个时段检测所对应的接触片的温度，以确定至少两个温度值，所述至少两个温度值与所述至少两个时段一一对应；
对至少两个温度值进行平均处理，以确定该充电接口的温度。
具体地说，对于任意一个测温元件(为了便于理解，以测温元件#A1为例)，可以在一次测温周期内多次(即，在至少两个时段)测量接触片#A1的温度，从而能够确定接触片#A1在不同时间点上的多个温度值(这里，该多个温度值可以相同也可以相异，本发明并未特别限定)。
从而，可以对该多个温度值进行平均处理，例如，计算算数平均值的处理等，并将所得到的平均值作为接触片#A1的温度值。
应理解，以上列举的平均处理的具体方式仅为示例性说明，本发明并未限定于此。
并且，以上列举的确定接口#A的接触片的温度的过程仅为示例性说明，本发明并不限定于此，例如，也可以只获取测温元件#A传输的一个温度信息，并将该唯一的温度值作为接口#A的接触片的温度，或者，也可以在接收测温元件#A传输的多个温度信息后，将数值最大的温度值确定为接口#A的接触片的温度。
可选地，通过设置在电源适配器的接口中的第一测温元件，确定该充电接口的温度，包括：
通过至少两个测温元件获取至少两个温度值，并对该至少两个温度值进行平均处理，以确定充电接口的温度，其中，该至少两个测温元件与该至少两个温度值一一对应。
具体地说，在本发明实施例中，当配置多个测温元件时，可以对各测温元件所测量到的所对应的接触片的温度值进行平均处理，并将处理得到的平均温度值作为接触片的温度值。
在本发明实施了中，在测量得到接触片的温度之后，可以直接将该接触片的温度作为接口#A的温度，或者，也可以对该该接触片的温度进行适当处理，例如，减去一个预设值，并将最终结果作为接口#A的温度，本发明并未特别限定，其他能够根据接触片的温度确定接口的温度的方法均落入本发明的保护范围内。
应理解，以上列举的测温元件#A的配置方式和测量对象仅为实例性说明，本发明并不限定于此，例如，也可以将测温元件#A配置在接口#A的外壳上，以测量接口#A的外壳的温度，并将接口#A的外壳的温度作为接口#A的温度。

具体地说，在本发明实施了中，可以在充电线缆中设置用于检测该接口#B的温度的测温元件(即，第二测温元件的一例，以下，为了便于理解和区分，记做：测温元件#B)。
从而，该充电线缆可以通过测温元件#B检测接口#B的温度。
并且，在本发明实施例中，该测温元件#B在接口#B中的配置方式和测试对象，与该测温元件#A在接口#A中的配置方式和测试对象相似，这里，为了避免赘述，省略其详细说明。
