具体实施方式
下面将结合本发明实施方式中的附图，对本发明实施方式中的技术方案进行清楚、完整地描述。显然，所描述的实施方式是本发明的一部分实施方式，而不是全部实施方式。基于本发明中的实施方式，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方式，都应属于本发明保护的范围。
本发明实施例提供一种充电方法及移动终端，可以缩短电池的充电时间。以下分别进行详细说明。
请参阅图1，图1是本发明实施例公开的一种充电方法的流程图。如图1所示，本实施例中所描述的充电方法，包括步骤：
101，当对电池进行恒流充电时，设置电池的初始截止电压和初始充电电流，初始截止电压大于电池的安全截止电压，并且初始截止电压与安全截止电压之差小于或等于预设电压差值。
本发明实施例中，电池的充电一般分为涓流充电、预充电、恒流充电、恒压充电四个过程。当电池电量很低、电池电压的当前值较低时，使用涓流充电(小电流充电)，当电池电压的当前值达到一定阈值时，进入预充电阶段，预充电结束后，进入恒流充电(快速充电阶段)，当电池电压的当前值达到截止电压时，进入恒压充电，直至电池电量充满。本发明实施例中，主要针对恒流充电的截止电压进行调整，可以延长恒流充电时间，缩短恒压充电时间，进而缩短总的充电时间。
本发明实施例中，当对电池进行恒流充电时，设置电池的初始截止电压和初始充电电流，初始截止电压为电池进入恒流充电时设置的截止电压，初始截止电压大于电池的安全截止电压，安全截止电压一般小于电池的安全电压，电池的安全电压由电池的电芯材料决定，例如，根据电芯材料的不同，电池的安全电压可以为4.3V、4.35V，4.4V等，对于电池的安全电压为4.3V的电芯来说，一般设置电池的安全截止电压为4.25V，设置初始截止电压为4.35V。预设电压差值可以设为固定值，如100毫伏(mV)，为了保证恒压充电的安全，安全截止电压一般设置为小于电池的安全电压50mV。初始充电电流为恒流充电的电流，初始充电电流根据电池容量的不同可以设置为800毫安(mA)，1000毫安(mA)，1200毫安(mA)等等，一般而言，电池的容量越大，初始充电电 流越大。
在一些可行的实施方式中，步骤101可以包括：
1011，检测电池的安全截止电压；
1012，根据安全截止电压与初始截止电压之间的对应关系设置电池的初始截止电压；
1013，根据初始截止电压和初始充电电流之间的对应关系设置电池的初始充电电流。
本发明实施例中，不同电芯材料的电池的安全截止电压不相同，可以通过充电芯片监测电池的安全截止电压，安全截止电压与初始截止电压之间的对应关系可以预先存储在移动终端，举例来说，4.25V(安全截止电压)对应4.35V(初始截止电压)，4.3V(安全截止电压)对应4.4V(初始截止电压)，4.35V(安全截止电压)对应4.45V(初始截止电压)。初始截止电压和初始充电电流之间的对应关系可以预先存储在移动终端，举例来说，4.35V(初始截止电压)对应1000mA(初始充电电流)，4.4V(初始截止电压)对应1100mA(初始充电电流)，4.45V(初始截止电压)对应1200mA(初始充电电流)。实施本发明实施例，可以根据不同电芯材料检测电池的安全截止电压，从而设置电池的初始截止电压和初始截止电流。
102，检测电池的电池电压。
本发明实施例中，可以通过移动终端中的充电芯片检测电池的电池电压，需要说明的是，由于在充电过程中电池有内阻，这里的测得的电池电压包括电池内阻的电压，因此，测得的电池电压要大于电池的实际电压。
103，判断电池电压的当前值是否等于初始截止电压。
本发明实施例中，判断电池电压的当前值是否等于初始截止电压，当电池电压的当前值小于初始截止电压时，电池仍处于恒流充电阶段，继续执行步骤103，当电池电压的当前值等于初始截止电压时，执行步骤104。
可选的，当电池电压的当前值不等于初始截止电压时，继续执行步骤103。
104，逐步调低初始截止电压和初始充电电流，直至初始截止电压小于或等于安全截止电压时，对电池进行恒压充电，恒压充电的电压为安全截止电压。
本发明实施例中，当电池电压的当前值等于初始截止电压时，逐步调低初 始截止电压和初始充电电流，例如，若初始截止电压为4.35V，安全截止电压为4.25V，初始充电电流为1000mA，当电池电压的当前值等于4.35V时，将初始截止电压调低至4.34V，初始充电电流调低至950mA，当电池电压的当前值等于4.34V时，将初始截止电压调低至4.335V，初始充电电流调低至925mA，当电池电压的当前值等于4.335V时，将初始截止电压调低至4.32V，初始充电电流调低至850mA，直至当电池电压的当前值小于或等于4.25V，对电池进行恒压充电，恒压充电的电压为4.25V。本发明实施例中，设置电池的初始截止电压大于电池的安全截止电压，当电池电压的当前值等于初始截止电压时，逐步调低初始截止电压和初始充电电流，直至初始截止电压小于或等于安全截止电压时，对电池进行恒压充电，实施本发明实施例，可以延长电池的恒流充电时间，进而缩短电池的恒压充电时间，可以缩短电池的充电时间。
在一些可行的实施方式中，步骤104可以包括：
1041，将初始截止电压调低第一预设值作为当前截止电压，将初始充电电流调低第二预设值作为当前充电电流。
1042，判断当前截止电压是否大于安全截止电压，若是，执行步骤1043，若否，对电池进行恒压充电。
1043，判断电池电压的当前值是否等于当前截止电压，若是，执行步骤1044，若否，继续执行步骤1043。
1044，将当前截至电压调低第一预设值作为新的当前截止电压，将当前充电电流调低第二预设值作为新的当前充电电流，执行步骤1042，直至当前截止电压小于或等于安全截止电压时，对电池进行恒压充电。
本发明实施例中，逐步调低初始截止电压时，将初始截止电压调低第一预设值作为当前截止电压，逐步调低初始充电电流时，将初始充电电流调低第二预设值作为当前充电电流。其中，第一预设值可以设为10mV，15mV，25mV等，第二预设值可以设为10mA，20mA，25mA等，例如，第一预设值可以设为25mV，第二预设值可以设为25mA。
下面以第一预设值为25mV，第二预设值为25mA为例，结合图2，对步骤1041～步骤1044进行说明。
图2是本发明实施例公开的充电电流和电池电压随充电时间的变化示意 图，如图2所示，图2是中的图(a)和图(b)为现有技术中的充电电流和电池电压随充电时间的变化示意图，图(c)和图(d)为本发明实施例中的充电电流和电池电压随充电时间的变化示意图，为了方便阐述，图2中仅仅显示了恒流充电阶段和恒压充电阶段。图(a)为现有技术中充电电流随充电时间的变化示意图，图(b)为现有技术中电池电压随充电时间的变化示意图，图(c)为本发明实施例中充电电流随充电时间的变化示意图，图(d)为本发明实施例中电池电压随充电时间的变化示意图。
如图2所示，若初始截止电压(图(d)中的U2)为4.35V，安全截止电压(图(b)和图(d)中的U1)为4.25V，初始充电电流(图(a)和图(c)中的I1)为1000mA，在恒流充电阶段，随着充电时间的增加，电池电压逐渐增加，充电电流均为1000mA(初始充电电流)，当电池电压的当前值达到4.25V(安全截止电压)时，在现有技术中，直接进入了恒压充电阶段，在本发明实施例中，由于设置的初始截止电压为4.35V，电池继续以1000mA进行充电，当电池电压的当前值达到4.35V时，电池电压的当前值等于初始截止电压，此时，将初始截止电压(4.35V)调低第一预设值(25mV)作为当前截止电压(4.325V)，将初始充电电流(1000mA)调低第二预设值(25mA)作为当前充电电流(975mA)，判断当前截止电压(4.325V)大于安全截止电压(4.25V)，判断电池电压的当前值是否等于当前截止电压(4.325V)，若否，继续判断电池电压的当前值是否等于当前截止电压，此时，由于电池电压的当前值随着充电时间逐渐增加，若是，将当前截至电压(4.325V)调低第一预设值(25mV)作为新的当前截止电压(4.3V)，将当前充电电流(975mA)调低第二预设值(25mA)作为新的当前充电电流(950mA)，此时，电池以950mA进行恒流充电；继续判断当前截止电压(4.3V)大于安全截止电压(4.25V)，判断电池电压的当前值是否等于当前截止电压(4.3V)，若否，继续判断电池电压的当前值是否等于当前截止电压，若是，将当前截至电压(4.3V)调低第一预设值(25mV)作为新的当前截止电压(4.275V)，将当前充电电流(950mA)调低第二预设值(25mA)作为新的当前充电电流(925mA)，此时，电池以925mA进行恒流充电；继续判断当前截止电压(4.275V)大于安全截止电压(4.25V)，判断电池电压的当前值是否等于当前截止电压(4.275V)，若否，继续判断电池电压的 当前值是否等于当前截止电压，若是，将当前截至电压(4.275V)调低第一预设值(25mV)作为新的当前截止电压(4.25V)，将当前充电电流(925mA)调低第二预设值(25mA)作为新的当前充电电流(900mA)，此时，电池以900mA进行恒流充电；继续判断当前截止电压(4.25V)等于安全截止电压(4.25V)，此时，进入恒压充电阶段。从图2中可以看出，现有技术中的恒流充电时长为t1，恒压充电时长为t2，本发明实施例中的恒流充电时长为t3，恒压充电时长为t4，虽然t3大于t1，但是t4远小于t2，对电池容量相同的电池进行充电时，总充电时长(t1+t2)大于(t3+t4)，实施本发明实施例，可以缩短电池的充电时间。
在一些可行的实施方式中，初始截止电压与安全截止电压之差为第一预设值的K倍，K为正整数。
例如，若初始截止电压为4.35V，安全截止电压为4.25V，则可设置第一预设值为10mV，此时，初始截止电压与安全截止电压之差为100mV，初始截止电压与安全截止电压之差为第一预设值的10倍。
本发明实施例中，当对电池进行恒流充电时，设置电池的初始截止电压和初始充电电流，初始截止电压大于电池的安全截止电压，并且初始截止电压与安全截止电压之差小于或等于预设电压差值；检测电池的电池电压；判断电池电压的当前值是否等于初始截止电压；当电池电压的当前值等于初始截止电压时，逐步调低初始截止电压和初始充电电流，直至初始截止电压小于或等于安全截止电压时，对电池进行恒压充电，恒压充电的电压为安全截止电压。实施本发明实施例，设置电池的初始截止电压大于电池的安全截止电压，可以延长电池的恒流充电时间，进而缩短电池的恒压充电时间，可以缩短电池的充电时间。

下面以第一预设值为25mV，第二预设值为25mA为例，结合图2，对步骤1041～步骤1044进行说明。
图2是本发明实施例公开的充电电流和电池电压随充电时间的变化示意图，如图2所示，图2是中的图(a)和图(b)为现有技术中的充电电流和电池电压随充电时间的变化示意图，图(c)和图(d)为本发明实施例中的充电电流和电池电压随充电时间的变化示意图，为了方便阐述，图2中仅仅显示了恒流充电阶段和恒压充电阶段。图(a)为现有技术中充电电流随充电时间的变化示意图，图(b)为现有技术中电池电压随充电时间的变化示意图，图(c)为本发明实施例中充电电流随充电时间的变化示意图，图(d)为本发明实施例中电池电压随充电时间的变化示意图。
如图2所示，若初始截止电压(图(d)中的U2)为4.35V，安全截止电压(图(b)和图(d)中的U1)为4.25V，初始充电电流(图(a)和图(c)中的I1)为1000mA，在恒流充电阶段，随着充电时间的增加，电池电压逐渐增加，充电电流均为1000mA(初始充电电流)，当电池电压的当前值达到4.25V(安全截止电压)时，在现有技术中，直接进入了恒压充电阶段，在本发明实施例中，由于设置的初始截止电压为4.35V，电池继续以1000mA进行充电，当电池电压的当前值达到4.35V时，电池电压的当前值等于初始截止电压，此时，第一调整子单元3041将初始截止电压(4.35V)调低第一预设值(25mV)作为当前截止电压(4.325V)，将初始充电电流(1000mA)调低第二预设值(25mA)作为当前充电电流(975mA)，第一判断子单元3042判断当前截止电压(4.325V)大于安全截止电压(4.25V)，第二判断子单元3043判断电池电压的当前值是否等于当前截止电压(4.325V)，若否，第二判断子单元3043继续判断电池电压的当前值是否等于当前截止电压，此时，由于电池电压的当前值随着充电时间 逐渐增加，若是，第二调整子单元3044将当前截至电压(4.325V)调低第一预设值(25mV)作为新的当前截止电压(4.3V)，将当前充电电流(975mA)调低第二预设值(25mA)作为新的当前充电电流(950mA)，此时，电池以950mA进行恒流充电；第一判断子单元3042继续判断当前截止电压(4.3V)大于安全截止电压(4.25V)，第二判断子单元3043判断电池电压的当前值是否等于当前截止电压(4.3V)，若否，第二判断子单元3043继续判断电池电压的当前值是否等于当前截止电压，若是，第二调整子单元3044将当前截至电压(4.3V)调低第一预设值(25mV)作为新的当前截止电压(4.275V)，将当前充电电流(950mA)调低第二预设值(25mA)作为新的当前充电电流(925mA)，此时，电池以925mA进行恒流充电；第一判断子单元3042继续判断当前截止电压(4.275V)大于安全截止电压(4.25V)，第二判断子单元3043判断电池电压的当前值是否等于当前截止电压(4.275V)，若否，第二判断子单元3043继续判断电池电压的当前值是否等于当前截止电压，若是，第二调整子单元3044将当前截至电压(4.275V)调低第一预设值(25mV)作为新的当前截止电压(4.25V)，将当前充电电流(925mA)调低第二预设值(25mA)作为新的当前充电电流(900mA)，此时，电池以900mA进行恒流充电；第一判断子单元3042继续判断当前截止电压(4.25V)等于安全截止电压(4.25V)，此时，进入恒压充电阶段。从图2中可以看出，现有技术中的恒流充电时长为t1，恒压充电时长为t2，本发明实施例中的恒流充电时长为t3，恒压充电时长为t4，虽然t3大于t1，但是t4远小于t2，对电池容量相同的电池进行充电时，总充电时长(t1+t2)大于(t3+t4)，实施本发明实施例，可以缩短电池的充电时间。
在一些可行的实施方式中，初始截止电压与安全截止电压之差为第一预设值的K倍，K为正整数。
例如，若初始截止电压为4.35V，安全截止电压为4.25V，则设置单元301可设置第一预设值为10mV，此时，初始截止电压与安全截止电压之差为100mV，初始截止电压与安全截止电压之差为第一预设值的10倍。
本发明实施例中，当对电池进行恒流充电时，设置单元301设置电池的初始截止电压和初始充电电流，初始截止电压大于电池的安全截止电压，并且初始截止电压与安全截止电压之差小于或等于预设电压差值；检测单元302检测 电池的电池电压；判断单元303判断电池电压的当前值是否等于初始截止电压；当电池电压的当前值等于初始截止电压时，调整单元304逐步调低初始截止电压和初始充电电流，直至初始截止电压小于或等于安全截止电压时，对电池进行恒压充电，恒压充电的电压为安全截止电压。实施本发明实施例，通过设置单元301设置电池的初始截止电压大于电池的安全截止电压，可以延长电池的恒流充电时间，进而缩短电池的恒压充电时间，可以缩短电池的充电时间。
