图1为本发明实施例1提供的一种电池充电方法的流程示意图；
图2为本发明实施例2提供的一种电池充电方法的流程示意图；
图3为本发明实施例3提供的一种电池充电装置的结构框图。
本发明的较佳实施方式
下面结合附图对本发明的实施方式进行描述。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的各种方式可以相互组合。
实施例1
本实施例提供了一种电池充电方法，如图1所示，本实施例方法的处理流程包括以下步骤：
步骤101、检测获得充电电池的电池温度。
电池在充电过程中，电池温度会升高，电池温度的升高的原因一部分是由于充电的电能转化为电池的热能，一部分是由于终端在使用过程中发热使电池本身的热量增加。
可选地，充电装置实时检测充电电池的电池温度，这样在电池温度较大时，充电装置就可以及时调整充电方法，防止充电电池的电池温度持续升高，造成一些安全隐患。
步骤102、在所述电池温度大于预设的温度阈值时，将当前充电电流调整为预设充电电流进行充电。
其中，所述预设充电电流可小于所述当前充电电流。
充电装置在检测到所述充电电池的电池温度大于预设的温度阈值时，表明所述电池温度已经到了一个较高水平，此时充电装置可调整充电方法，将当前充电电流调整为预设充电电流进行充电，其中，所述预设充电电流可小于所述当前充电电流。由于以较小充电电流对电池进行充电可以起到对电池进行降温的作用，故当充电装置调整为预设充电电流进行充电时，可抑制电池温度的升高。这样当电池温度上升到温度阈值时，还可以继续用较小的电流来继续充电，避免发生电池温度升高后可能会出现的一直插有适配器而电池不能充电的问题。
电池在充电过程中，如果电池电压达到电池的额定限制电压，充电装置可停止充电，这里所述的额定限制电压可以是指，当充电电池充足电时，继续充电的话，电池电压也不会上升，此时的电池电压可称为额定限制电压。
可选地，当然，充电装置在检测到充电电池的电池温度小于或等于预设的温度阈值时，表明充电电池当前的电池温度还不是很高，继续按照相关技术中的充电方法进行充电，直至电池电压达到电池的额定限制电压时，停止充电。
在这里需要说明的是，本实施例方法中所述的温度阈值一般较高，示例的温度阈值，可以是45℃-52℃；预设充电电流可为电池电芯在较高温度下允许充电的电流，如0.5C或更小，0.5C即充电电池容量的0.5倍率，C(Capacity，电池容量)表示充电电池容量，假设充电电池容量为1000mAh，则预设充电电流为0.5C表示充电电流为0.5*1000mA＝500mA。
实施例2
本实施例提供了一种电池充电方法，如图2所示，本实施例方法的处理流程包括以下步骤：
步骤201、检测获得充电电池的电池温度和电池电压。
电池在充电过程中，电池温度会升高，电池温度的升高的原因一部分是 由于充电的电能转化为电池的热能，一部分是由于终端在使用过程中发热使电池本身的热量增加。
可选地，充电装置实时检测充电电池的电池温度，这样在电池温度较大时，充电装置就可以及时调整充电方法，防止充电电池的电池温度持续升高，造成一些安全隐患。
另外，可选地，充电电池在电池温度较大的情况下，如果电池电压过高，也可能产生一定的安全隐患，故充电装置还需要检测获得充电电池的电池电压，避免电池在高温高压的条件下充电。
步骤202、在所述电池温度大于预设的温度阈值时，调整所述充电电池的限制电压为预设限制电压。
所述预设限制电压小于充电电池的额定限制电压。
充电装置在检测到所述充电电池的电池温度大于预设的温度阈值时，表明所述电池温度已经到了一个较高水平，出于安全考虑，此时充电装置可将所述充电电池的限制电压调整为小于额定限制电压的预设限制电压，即将限制电压调小。
可选地，这里，预设限制电压设置得不能过低，以保证电池在停止充电时，电池电量处于较高水平，同时，预设限制电压设置得不能过高，可为充电电池在较高温度下允许充电的适当电压。以锂电池为例，锂电池的额定限制电压一般为4.24V，预设限制电压一般可以设置为4V。通常可根据不同电池产品，设置出合理的预设限制电压。
可选地，当然，充电装置在检测到充电电池的电池温度小于或等于预设的温度阈值时，表明充电电池当前的电池温度还不是很高，继续按照相关技术中的充电方法进行充电，直至电池电压达到电池的额定限制电压时，停止充电。
在这里需要说明的是，本实施例方法中所述的温度阈值一般较高，示例的温度阈值，可以是45℃-52℃。
步骤203、在所述电池电压小于所述预设限制电压时，将当前充电电流调整为预设充电电流进行充电。
在所述电池电压小于所述预设限制电压时，表明电池电压还不是很高，还在充电的安全范围内，仍然可以继续充电，此时所述充电装置可以将当前充电电流调整为预设充电电流进行充电，其中，所述预设充电电流可小于所述当前充电电流。由于以较小充电电流对电池进行充电可以起到对电池进行降温的作用，故当充电装置调整为预设充电电流进行充电时，可抑制电池温度的升高。这样当电池温度上升到温度阈值时，还可以继续用较小的电流来继续充电，避免发生电池温度升高后可能会出现的一直插有适配器而电池不能充电的问题。
所述预设充电电流可为电池电芯在较高温度下允许充电的电流，如0.5C或更小。
步骤204、在所述电池电压大于等于所述预设限制电压时，停止充电。
在所述电池电压大于或等于所述预设限制电压时，表明电池电压过高，在该电池温度超过温度阈值的情况下，继续充电可能会造成一些安全隐患，故可停止电池充电。
