通过上述附图，已示出本公开明确的实施例，后文中将有更详细的描述。这些附图和文字描述并不是为了通过任何方式限制本公开构思的范围，而是通过参考特定实施例为本领域技术人员说明本公开的概念。
具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
本公开实施例中的移动终端是指使用充电电池进行供电的电子设备，该移动终端可以是手机、平板电脑、电子书阅读器、MP3播放器(Moving Picture Experts Group Audio Layer III，动态影像专家压缩标准音频层面3)、MP4(Moving Picture Experts Group Audio Layer IV，动态影像专家压缩标准音频层面3)播放器和膝上型便携计算机等等。
图1是根据一示例性实施例示出的一种充电管理方法的流程图，本实施例以该充电管理方法应用于移动终端中来举例说明。该充电管理方法可以包括如下几个步骤：
在步骤101中，在充电过程中，获取目标充电电流值和实际充电电流值，该目标充电电流值是为当前充电过程设定的期望充电电流值。
目标充电电流值是移动终端为当前充电过程设定的期望充电电流值，可以记为I目标。
实际充电电流值是从充电电池端所测量到的电流值，可以记为I实际。实际充电电流值通常小于目标充电电流值。
在步骤102中，根据目标充电电流值和实际充电电流值计算消耗电流值。
可选地，消耗电流值I消耗＝目标充电电流值I目标-实际充电电流值I实际。消耗电流值I消耗主要是第一芯片源所消耗的电流，也即CPU、GPU和内存所消耗的电流。
消耗电流值I消耗越小，表明移动终端当前的负载越小，用户可能并没有使用移动终端。
消耗电流值I消耗越大，表明移动终端当前的负载越大，用户可能正在使用移动终端。
在步骤103中，根据消耗电流值的大小调整目标充电电流值。
其中，消耗电流值的大小与调整后的目标充电电流值呈负相关关系。也即：
在消耗电流值I消耗较小时，用户可能并没有使用移动终端，可以采用较大的目标充电电流值I目标，保证充电速度。
在消耗电流值I消耗较大时，用户可能正在使用移动终端，可以采用较小的目标充电电流值I目标，减少发热量。
综上所述，本实施例提供的充电管理方法，通过在充电过程中，获取目标充电电流值和实际充电电流值，根据该目标充电电流值和该实际充电电流值计算消耗电流值，根据该消耗电流值的大小调整该目标充电电流值；解决了移动终端在充电过程中会发出较多热量的问题；达到了目标充电电流值根据消耗电流值的大小动态调整，移动终端的发热量也随着消耗电流值的大小而改变的效果。
图2是根据另一示例性实施例示出的一种充电管理方法的流程图，本实施例以该充电管理方法应用于移动终端中来举例说明。该充电管理方法可以包括如下几个步骤：
在步骤201中，在充电过程中，获取目标充电电流值和实际充电电流值，该目标充电电流值是为当前充电过程设定的期望充电电流值。
在充电过程中，移动终端每隔预定采样间隔，采样一次目标充电电流值I目标和实际充电电流值I实际。目标充电电流值是移动终端为当前充电过程设定的期望充电电流值。实际充电电流值是移动终端从充电电池端所测量到的电流值。
比如，移动终端每隔30秒，采样一次目标充电电流值I目标和实际充电电流值I实 际。
表一示例性地示出了一种采样结果。
采样时刻 目标充电电流值 实际充电电流值
采样时刻1 电流值11 电流值12
采样时刻2 电流值21 电流值22
采样时刻3 电流值31 电流值32

表二
在步骤203中，计算属于预定时间段内的至少一个差值的平均值，将该平均值作为消耗电流值，该预定时间段内包括至少一个采样时刻。
该预定时间段可以是每隔预定时间间隔所确定出的时间段。
比如，根据2分钟为预定时间间隔确定出一个个连续的预定时间段。在每个预定时间段中，包括有4个采样时刻。
对于每个预定时间段，移动终端计算属于预定时间段内的至少一个差值的平均值，将该平均值作为消耗电流值。比如，移动终端计算电流值13、电流值23、电流值33和电流值43的平均值，将该平均值作为消耗电流值I消耗。
在步骤204中，根据该消耗电流值查询预设的对应关系，得到与消耗电流值对应的目标充电电流值。
该对应关系包括有至少一个消耗电流值区间和每个消耗电流值区间所对应的目标充电电流值。该对应关系中的消耗电流值区间与目标充电电流值之间呈负相关关系。
表三示例性地示出了该对应关系。其中，第一阈值小于第二阈值，第二阈值小于第三阈值，第三阈值小于第四阈值。
消耗电流值区间 目标充电电流值
当消耗电流值处于(0，第一阈值) 最大充电电流值*100％
当消耗电流值处于(第二阈值，第三阈值) 最大充电电流值*80％
当消耗电流值处于(第三阈值，第四阈值) 最大充电电流值*70％
当消耗电流值处于(第四阈值，最大值) 消耗电流值
表三
比如，当消耗电流值小于第一阈值时，移动终端可以将目标充电电流值调整为最大充电电流值，然后根据调整后的目标充电电流值继续充电。
比如，当消耗电流值大于第三阈值小于第四阈值时，移动终端可以将目标充电电流值调整为最大充电电流值*70％，然后根据调整后的目标充电电流值继续充电。
综上所述，本实施例提供的充电管理方法，通过在充电过程中，获取目标充电电流值和实际充电电流值，根据该目标充电电流值和该实际充电电流值计算消耗电流值，根据该消耗电流值的大小调整该目标充电电流值；解决了移动终端在充电过程中会发出较多热量的问题；达到了目标充电电流值根据消耗电流值的大小动态调整，移动终 端的发热量也随着消耗电流值的大小而改变的效果。
图3是根据另一示例性实施例示出的一种充电管理方法的流程图，本实施例以该充电管理方法应用于移动终端中来举例说明。该充电管理方法可以包括如下几个步骤：
在步骤301中，在充电过程中，获取目标充电电流值和实际充电电流值，该目标充电电流值是为当前充电过程设定的期望充电电流值。
在充电过程中，移动终端每隔预定采样间隔，采样一次目标充电电流值I目标和实际充电电流值I实际。目标充电电流值是移动终端为当前充电过程设定的期望充电电流值。实际充电电流值是移动终端从充电电池端所测量到的电流值。
比如，移动终端每隔30秒，采样一次目标充电电流值I目标和实际充电电流值I实 际。
在步骤302中，计算相同采样时刻采集到的目标充电电流值和实际充电电流值之间的差值。
移动终端计算相同采样时刻采集到的目标充电电流值I目标和实际充电电流值I实际之间的差值。
在步骤303中，计算属于预定时间段内的至少一个差值的平均值，将该平均值作为消耗电流值，该预定时间段内包括至少一个采样时刻。
该预定时间段可以是每隔预定时间间隔所确定出的时间段。
比如，根据2分钟为预定时间间隔确定出一个个连续的预定时间段。在每个预定时间段中，包括有4个采样时刻。
对于每个预定时间段，移动终端计算属于预定时间段内的至少一个差值的平均值，将该平均值作为消耗电流值I消耗。
在步骤304中，检测屏幕是否处于工作状态。
移动终端还可以通过检测屏幕是否处于工作状态，来判断移动终端当前是否处于被用户使用的状态。
若屏幕处于工作状态，则进入步骤305；若屏幕处于关闭状态，则进入步骤306。
同时，移动终端中可以预先存储有两套对应关系，分别为第一对应关系和第二对应关系。每个对应关系都包括有至少一个消耗电流值区间和每个消耗电流值区间所对应的目标充电电流值。
在处于被用户使用的状态时，移动终端使用第一对应关系来确定目标充电电流值，从而兼顾发热量和充电速度。在处于未被用户使用的状态时，移动终端使用第二对应关系来确定目标充电电流值，优先保证充电速度。所以，同一个消耗电流值在第一对应关系中所对应的目标充电电流值小于等于在第二对应关系中所对应的目标充电电流值。
在步骤305中，若屏幕处于工作状态，则确定当前处于被用户使用的状态，根据 消耗电流值查询第一对应关系，得到与消耗电流值对应的目标充电电流值。
表四示例性地示出了该第一对应关系。该第一对应关系中的消耗电流值区间与目标充电电流值之间呈负相关关系。
消耗电流值区间 目标充电电流值
当消耗电流值处于(0，400mA) 最大充电电流值*100％
当消耗电流值处于[400mA，700mA) 最大充电电流值*80％
当消耗电流值处于[700mA，1100mA) 最大充电电流值*70％
当消耗电流值处于[1100mA，最大值) 消耗电流值
表四
比如，消耗电流值为500mA，则移动终端将目标充电电流值调整为最大充电电流值*80％。
在步骤306中，若屏幕处于关闭状态，则确定当前处于未被用户使用的状态，根据消耗电流值查询第二对应关系，得到与消耗电流值对应的目标充电电流值。
表五示例性地示出了该第二对应关系。该第二对应关系中的消耗电流值区间与目标充电电流值之间呈负相关关系。
消耗电流值区间 目标充电电流值
当消耗电流值处于(0，1000mA) 最大充电电流值*100％
当消耗电流值处于[1000mA，1500mA) 最大充电电流值*90％
当消耗电流值处于[1500mA，最大值) 消耗电流值
表五
比如，消耗电流值为1100mA，则移动终端将目标充电电流值调整为最大充电电流值*90％。
在步骤307中，根据调整后的目标充电电流继续充电。
综上所述，本实施例提供的充电管理方法，通过在充电过程中，获取目标充电电流值和实际充电电流值，根据该目标充电电流值和该实际充电电流值计算消耗电流值，根据该消耗电流值的大小调整该目标充电电流值；解决了移动终端在充电过程中会发出较多热量的问题；达到了目标充电电流值根据消耗电流值的大小动态调整，移动终端的发热量也随着消耗电流值的大小而改变的效果。

本实施例提供的充电管理方法，还通过移动终端处于未被用户使用的状态时，根据第二对应关系来确定目标充电电流值，优先保证充电速度。
