Description

终端 技术领域
本发明实施例涉及充电领域，并且更具体地，涉及一种终端。
背景技术
终端类型很多，如手机，掌上电脑等，以手机为例，现第三方已针对手机开发出大量的应用程序，丰富了手机的功能。具有丰富功能的手机，已逐渐成为人们随身携带物品。随着手机的使用频率逐渐增多，手机的电池能存储的电量是有限的，因此需要经常充电。
手机电池都有适宜的工作温度，温度太低会影响手机充电的效率。以锂电池为例，锂电池在-10～55摄氏度的温度范围内都可以工作，但充电比较适合的温度范围是5～45摄氏度，尤其10～35摄氏度的范围更佳，而在5～45摄氏度以外的温度范围其充电效果变差，尤其当温度低于5摄氏度时其充电效果更差。原因是随着温度的降低，锂离子的活性会变差，容易在石墨晶体表面沉积形成锂金属，形成的锂金属会与电解液发生不可逆的反应，从而导致锂电池长时间只能充进少的电量甚至充不进电。此外，如果锂电池长期在低温下充电，不仅会造成容量下降，而且会影响使用寿命。因此，所以很多手机均设置了当锂电池的温度低于一定温度时自动中断充电。
综上所述，现有技术尚未解决终端在低温环境下的充电问题。

结合第一方面或其上述实现方式的任一种，在第一方面的另一种实现方式中，所述加热装置包括加热电路和加热膜，所述加热电路通过所述加热膜为所述电池加热，所述加热膜套在所述外壳的表面，或者所述加热膜贴在所述外壳的表面，或者所述加热膜设置在所述电池槽的内表面，或者所述加热膜设置在所述终端的后盖的内表面，且所述后盖盖合时，所述加热膜贴在所述电池的外表面上，或者所述加热膜设置在所述电池内部。
结合第一方面或其上述实现方式的任一种，在第一方面的另一种实现方 式中，所述加热膜内设置有曲折迂回形状的电阻丝。
本发明实施例中，当电池的温度小于第一阈值时，终端控制充电回路保持断开，为电池加热，当电池的温度大于第一阈值时，终端控制充电回路导通，为电池充电，从而能够保证电池在合适的温度下进行充电，解决了较低温度下的充电难的问题。
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是本发明实施例的终端的示意性框图。
具体实施方式
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楚、完整地描述，显然，所描述的实施例是本发明的一部分实施例，而不是全部实施例。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，都应属于本发明保护的范围。
图1是本发明实施例的终端的示意性框图。图1的终端10包括电池11和充电接口12，终端10通过充电接口12与电源适配器形成充电回路，为电池11充电，终端10还包括温度检测电路13、控制电路14和加热装置15，其中，
当电源适配器和终端10连接时，控制电路14通过温度检测电路13检测电池11的温度，如果检测到电池11的温度小于第一阈值，控制电路14保持充电回路断开，并控制加热装置15为电池11加热；如果检测到电池11的温度大于第一阈值，控制电路14控制充电回路导通，为电池11充电。
举例说明，可以将第一阈值设定为0摄氏度，当检测到电池温度小于0摄氏度时，控制电路14保持充电回路断开，并控制加热装置15为电池11加热；当检测到电池温度大于0度时，控制电路14控制充电回路导通，为电池11充电。需要说明的是，第一阈值的设定与电池的种类、容量等许多参数有关，可以根据实际情况设定该第一阈值，比如，电池在0摄氏度以下 充电效果较差，在0-5摄氏度充电效果一般，5摄氏度以上充电效果较好，也可以将第一阈值设定为5摄氏度。
本发明实施例中，当电池的温度小于第一阈值时，终端控制充电回路保持断开，为电池加热，当电池的温度大于第一阈值时，终端控制充电回路导通，为电池充电，从而能够保证电池在合适的温度下进行充电，解决了较低温度下的充电难的问题。
可选地，作为一个实施例，如果检测到电池的温度大于第一阈值，且小于第二阈值，控制电路14控制充电回路使用普通充电模式为电池充电；如果检测到电池的温度大于第二阈值，控制电路14控制充电回路使用快速充电模式为电池充电；其中，快速充电模式的充电电流大于普通充电模式的充电电流。
举例说明，可以将第一阈值设定为0摄氏度，第二阈值设定为10摄氏度。如果检测到电池的温度处于0-10摄氏度这一区间，表示终端可以为电池充电，但不宜采用过大的充电电流，此时可使用普通充电模式，将电流控制在1A-3A之间；如果检测到电池的温度高于10摄氏度，表示电池处于较佳的温度环境，可以使用快速充电模式，通过较大的电流为电池充电，例如，将充电电流设定为4A甚至高于4A。
可选地，如果检测到电池的温度大于第三阈值，控制电路14控制充电回路断开，其中，第三阈值大于第二阈值。
例如，第三温度设置为45摄氏度，当电池11的温度高于45摄氏度时，表示电池11的温度过高，继续充电会可能会发生故障，此时控制电路14控制充电回路断开。
可选地，作为一个实施例，控制电路14控制加热装置15为电池11加热，具体包括：当电池11的温度未加热至第一阈值时，控制电路14保持充电回路断开；当电池11的温度加热至第一阈值时，控制电路14控制充电回路导通，为电池充电。
举例说明，第一阈值可以设定为0摄氏度，当在寒冷的环境(例如，温度为零下15摄氏度)为手机充电时，控制电路14先为电池11加热，当电池11还未达到0摄氏度，仍然不宜为电池11充电；当电池11加热至0摄氏度，表示电池11达到了可充电的温度，此时，控制电路14控制充电回路导通，为电池11充电。
可选地，作为一个实施例，当电池11的温度加热至第一阈值时，控制电路14控制充电回路为电池11充电，具体包括：当电池11的温度被加热至第一阈值时，控制电路14控制充电回路使用普通充电模式为电池11充电；当电池11的温度被加热至第四阈值时，控制电路14控制充电回路使用快速充电模式为电池11充电；其中，第四阈值大于第一阈值，且快速充电模式的充电电流大于普通充电模式的充电电流。
举例说明，第四阈值可以设定为10摄氏度，当加热装置15将电池11加热至0摄氏度时，表示电池达到了可充电的温度，但不宜采用大的充电电流，此时可以使用普通充电模式为终端充电，普通充电模式的充电电流可以设置为1A-3A；当加热装置15将电池11加热至10摄氏度时，表示电池11的温度环境较佳，可以采用大电流为电池充电，此时使用快速充电模式为终端充电，快速充电模式的充电电流可以设置为4A，甚至更大。
可选地，作为一个实施例，控制电路14控制充电回路为电池11充电，还可包括：当电池11的温度被加热至第五阈值时，控制电路14控制加热装置15断开，其中，第五阈值大于或等于第四阈值。
举例说明，可以将第五阈值设定为45摄氏度，表示对电池11加热不宜超过45摄氏度，超过45摄氏度后充电效果较差，甚至可能损坏电池11。
可选地，作为一个实施例，加热装置15包括加热电路和加热膜，加热电路通过加热膜为电池加热，加热膜套在外壳的表面，或者加热膜贴在外壳的表面，或者加热膜设置在电池槽的内表面，或者加热膜设置在终端的后盖的内表面，且后盖盖合时，加热膜贴在电池的外表面上，或者加热膜设置在电池内部。
可选地，作为一个实施例，加热膜内设置有曲折迂回形状的电阻丝。该电阻丝具有大阻值，电流流过该电阻丝之后会产生大量热能，从而为电池加热。
