附图说明
为了更清楚地说明本发明实施例的技术方案，下面将对本发明实施例中所需要使用的附图作简单地介绍，显而易见地，下面所描述的附图仅仅是本 发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1是本发明实施例的电池保护板的示例性电路图。
图2是本发明实施例的电池保护板的示意性结构图。
图3是本发明实施例的电池保护板的示意性电路图。
图4是本发明实施例的电池的示意性结构图。
图5是本发明实施例的移动终端的示意性结构图。
具体实施方式
由上文可知，现有技术中，温度检测电路检测的是电池保护板的温度，并将电池保护板的温度近似为电芯的温度。当电流回路的电流较小时，二者的温度可以近似相等。但是，随着快充技术的普及，电流回路的电流越来越大，电池保护板的发热量也越来越大，电池保护板的温度实际上会比电芯高许多。此时，如果仍然用电池保护板的温度近似电芯的温度，会产生较大的检测误差。
为了降低电芯温度的检测误差，下面结合图1和图2，详细描述本发明实施例的电池保护板。
图1是本发明实施例的电池保护板的示意性电路图。图1的电池保护板10包括：
保护电路11，与移动终端的充放电回路13相连，保护电路11用于控制充放电回路13的导通与关断；
温度检测电路14，温度检测电路14与电池保护板10上的热敏电阻15相连，温度检测电路14通过热敏电阻15检测移动终端的电芯12的温度。
在一些实施例中，图1中的保护电路11包括控制IC 16和一对儿背靠背的MOS管T1和T2，控制IC 16分别通过Cout端和Dout端与MOS管T1和MOS管T2相连。
在一些实施例中，Cout端可以是过充控制端，通过MOS管T2栅极电压控制MOS管的开关。
在一些实施例中，Dout端可以是过放、过流或短路控制端，通过MOS管T1栅极电压控制MOS管的开关。
在一些实施例中，P+和P-分别代表电池保护板10的正极和负极。或者， P+和P-分别代表通过电池保护板10接出来的电芯12的正极和负极。
在一些实施例中，电池保护板10还可以包括电池电量计，温度检测电路14的温度检测功能可以集成在电池电量计中。
现有技术中，温度检测电路14的下方铺设有地层，这样一来，电池保护板的其他电路产生的热量会通过该地层传导至热敏电阻处，为了避免这一现象的发生，参见图2，本发明实施例在电池保护板10的热敏电阻15所在区域的下方不再铺设地层，而是将其下方挖空，形成挖空区域17，温度检测电路14的负极通过接地线18直接连接至电池保护板10的主地19。通过这样的方式，相当于对温度保护电路14进行了隔热处理，将其与电池保护板10其他热源隔离开来，降低电池保护板的温度对热敏电阻的影响，使其检测到的温度更加接近电芯的温度。
应理解，主地19可以位于电池保护板10的主地层，但本发明实施例对主地层在电池保护板10中的具体位置不作限定，例如，可以位于电池保护板10的某两个板层之间。
此外，温度检测电路14可以位于电池保护板的边缘区域，保证其不在电池保护板的热源的中心，进一步提高温度检测准确性。
在一些实施例中，参见图1，热敏电阻15的一端可以通过上拉电阻与电池保护板10的正极P+相连。
上述保护电路11可以是电池保护板10中的第一保护电路，为了进一步提高电池保护板的保护性能，可选地，在一些实施例中，参见图3，电池保护板10还可包括：第二保护电路21，第二保护电路21可以在第一保护电路11失效的情况下，为电池的充放电过程提供保护。
在一些实施例中，第二保护电路21可以通过熔丝为电池的充放电过程提供过压或过流保护。如图3所示，第二保护电路21可以包括第一熔丝引脚F1和第二熔丝引脚F2，当充放电回路13出现过压或过流时，第二保护电路21中的位于第一熔丝引脚F1和第二熔丝引脚F2之间的熔丝熔断。
上文结合图1至图3，详细描述了本发明实施例的电池保护板。下文结合图4和图5，详细描述本发明实施例的电池和移动终端。
图4是本发明实施例的电池的示意性结构图。图4的电池400包括：
电芯410；以及
电池保护板420，所述电池保护板420与所述电芯410相连。
应理解，图4中的电池保护板420可以采用上文描述的电池保护板，为避免重复，此处不再详述。
图5是本发明实施例的移动终端的示意性结构图。图5的移动终端500包括：
充电接口510；
电池400，所述电池400与所述充电接口510相连。
可选地，作为一个实施例，移动终端500可以支持普通充电模式和快速充电模式，其中，快速充电模式的充电速度大于普通充电模式的充电速度。
可选地，作为一个实施例，快速充电模式的充电电流大于普通充电模式的充电电流。
可选地，作为一个实施例，在快速充电模式下，移动终端500通过充电接口510与适配器进行双向通信。
本发明实施例对移动终端与适配器之间的通信过程不作具体限定，例如，移动终端与适配器之间的通信可以指双方的握手过程，即移动终端和适配器通过握手确定充电模式、充电电压、充电电流等参数。

所属领域的技术人员可以清楚地了解到，为描述的方便和简洁，上述描述的系统、装置和单元的具体工作过程，可以参考前述方法实施例中的对应过程，在此不再赘述。

另外，在本发明各个实施例中的各功能单元可以集成在一个处理单元中，也可以是各个单元单独物理存在，也可以两个或两个以上单元集成在一个单元中。
