背景技术
锂离子电池是一种二次电池(即充电电池),它主要依靠锂离子在正极和负极之间移动来工作,其具有能量密度高、无记忆效应等优点,被广泛的应用于各个领域。但是由于锂电池的一些特性限制,使得其在充电时,对环境的要求较为严格,当环境温度较低时,锂离子的活性较低,此时如果采用常温下同样大小的电流进行充电,会在负极石墨上沉积金属锂,使得电池的寿命降低、膨胀率增加。因此,为保证电池的寿命,在低温条件下充电时需要减小充电电流,但是减小充电电流又会带来充电完成时间增加的问题。

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一部分实施例,而不是全部的实施例。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,都属于本发明保护的范围。
本发明提供了一种电池及其控制方法和电子设备,该电池在低温环境下不需要外加加热装置,只需通过电池的正极加热极耳3、正极耳1、负极耳2和负极加热极耳4,就可以为电池的正极片和负极片加热,不增加电池的体积,通过内部加热既保证了电池的使用寿命,又保证了充电效率。
如图1-2所示,为本发明实施例提供的一种电池的结构示意图。如图所示,该电池包括:正极耳1、负极耳2、正极加热极耳3、负极加热极耳4和加热电路。
其中,正极耳1的第一端与正极加热极耳3的第一端均与电池的正极片连接,正极耳1的第二端与正极加热极耳3的第二端分别与加热电路连接;负极耳2的第一端与负极加热极耳4的第一端均与电池的负极片连接,负极耳2的第二端与负极加热极耳4的第二端分别与加热电路连接。
其中,加热电路用来为电池的正极片与负极片进行加热。
在本发明实施例中,通过在电池的正极片上添加正极加热极耳3,在负极片上添加负极加热极耳4,在环境温度小于第一预设值的情况下,控制加热电路通过正极耳1与正极加热极耳3对正极片加热,控制加热电路通过负极耳2与负极加热极耳4对负极片加热,也就是,可以通过电池内部的正负极片对电池进行加热,不需要增加其他外部加热装置,即可实现对电池的加热,在环境温度较低时,通过内部加热既保证了电池的使用寿命,又保证了充电效率。
具体地,正极片可以是铝箔,负极片可以是铜箔,正极片与负极片还可以是其他材料的极片,本发明实施例中不做具体限定。
本发明实施例通过为电池正、负电极中的正极片和负极片进行加热,进而加热电池,也就是在正极片上连接正极加热极耳3,在负极片上连接负极加热极耳4,当电池温度较低时,开启正极加热极耳3和正极耳1之间的加热电路,加热正极片,同时,开启负极加热极耳4和负极耳2之间的加热电路,加热负极片,可以利用电池内部的正负极片加热电池,由于正负极片与电池内部的活性物质紧密接触,加热过程中能够使电池内部的温度受热更加均匀,延长电池的寿命。
在本发明的一个可能的实施方式中,加热电路可以为一个电路,同时为正极片和负极片加热,加热电路也可以为两个电路,即第一加热模块和第二加热模块。
具体地,第一加热模块分别与正极耳1的第二端和正极加热极耳3的第二端连接,用于加热正极片;第二加热模块分别与负极耳2的第二端和负极加热极耳4的第二端连接,用于加热负极片。
也就是,可以通过两个加热模块分别对正负极片进行加热,使得对正负极的加热更加均匀,进而使得电池内部的温度受热更加均匀,延长电池的寿命。
进一步地,第一加热模块可以包括第一限流电阻,第二加热模块可以包 括第二限流电阻。

具体地,开关电路可以是一个开关,以用于在加热电路为一个电路时,控制加热电路的导通和断开。开关电路也可以为两个开关,以用于在加热电路为两个电路即第一加热模块和第二加热模块时,分别控制第一加热模块和第二加热模块的与正负极片的导通和断开。
也就是,通过一个开关来直接控制加热电路,可以使得控制更为方便,通过两个开关分别控制第一加热模块和第二加热模块,可以精确的控制正极片和负极片的加热,使得电池内部受热更加均匀。
值得说明的是,开关的具体位置可以是在第一加热模块和正极耳之间,也可以是在第一加热模块和正极加热极耳之间,还可以是其他位置,本发明中不做具体限定。
在本发明的一个可能的实施方式中,正极耳1的第一端与正极片的一端连接,正极加热极耳3的第一端与正极片上背离正极耳1的一端连接。
也就是,正极耳1与正极加热极耳3分别位于正极片的两端,这样可以增加正极片的受热面积,使得电池的升温更快,同时受热更为均匀,不会缩短电池寿命,也不影响电池能量密度。
在本发明的一个可能的实施方式中,负极耳2的第一端与负极片连接,负极加热极耳4的第一端与负极片上背离负极耳2的一端连接。
也就是,负极耳2与负极加热极耳4分别位于负极片的两端,这样可以增加负极片的受热面积,使得电池的升温更快,同时受热更为均匀,不会缩 短电池寿命,也不影响电池能量密度。
本发明中的电池具有电池管理系统,以使在接收到相应的信号时,控制加热电路的断开或闭合。从而可以在天气寒冷的时候控制加热电路开启,当电池的温度达到一定值后控制加热电路断开,使得电池的性能更好,延长电池的使用寿命。
本发明实施例还提供了一种电池的控制方法,如图3所示,为本发明实施例提供的一种电池的控制方法的流程图。该电池的控制方法可以包括以下步骤。
S101、在环境温度小于第一预设值的情况下,控制加热电路导通,以使充电电流通过电池的正极耳与正极加热极耳为电池的正极片加热,通过电池的负极耳与负极加热极耳为电池的负极片加热,且通过所述电池的正极耳与负极耳对电池进行充电。
S102、在环境温度大于或等于第一预设值的情况下,控制加热电路断开,以使充电电流通过电池的正极耳与负极耳对电池进行充电。
在本发明实施例中,通过环境温度的高低,来确定是为电池边加热边充电还是直接为电池充电,当电池温度较低时,开启正极加热极耳和正极耳之间的加热电路,加热正极片,同时,开启负极加热极耳和负极耳之间的加热电路,加热负极片,然后通过正极耳与负极耳对电池进行充电,可以利用电池内部的正负极片加热电池,由于正负极片与电池内部的活性物质紧密接触,加热过程中能够使电池内部的温度受热更加均匀,延长电池的寿命。
具体地,控制加热电路导通,以使充电电流通过电池的正极耳与正极加热极耳为电池的正极片加热,通过电池的负极耳与负极加热极耳为电池的负极片加热,可以包括以下步骤。
控制加热电路的第一加热模块导通,以使充电电流通过电池的正极耳与正极加热极耳为电池的正极片加热;
控制加热电路的第二加热模块导通,以使充电电流通过电池的负极耳和 负极加热极耳为电池的负极片加热。
在本发明实施例中,通过分别控制两个加热模块的导通,来分别对正负极片进行加热,可以精准的控制两个极片的温度,以使得电池内部的温度受热更加均匀,延长电池的寿命。
在本发明的一个可能的实施方式中,控制加热电路导通,可以包括:控制加热电路的开关电路导通;控制加热电路断开,可以包括:控制加热电路的开关断开。
在本发明实施例中,通过在加热电路中设置开关电路,以使得在电池内部需要加热时使得开关电路导通,在不需要加热时断开开关电路,可以更加方便的控制加热电路的工作,避免电池内部加热的温度过高,减短电池寿命。
在本发明的一个可能的实施方式中,该电池的控制方法还可以包括以下步骤。
在电池的温度大于第二预设值的情况下,控制加热电路断开;通过电池的正极耳与负极耳对电池进行充电。
也就是,对电池加热的情况下,若是检测到电池的温度达到第二预设值,则停止对电池的加热,只对电池进行充电,可以保证电池在寒冷的条件下,还是可以以正常充电的电流进行充电,既不影响充电效率,又可以保证电池的使用寿命不会缩短。
