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是根据本发明的一个实施例的充电系统的示意性流程图。充电系统100包括可充电设备110和充电器120。应理解，可充电设备110和充电器120可以是分离的，也可以是一体的。可充电设备110可以包括操作系统(例如嵌入式系统等)和应用程序(例如各类应用软件)，其中充电系统(例如充电管理模块)通过用户设置、系统关联或程序关联方式识别用户充电时间需求；其中操作系统、应用程序和充电系统都集成在可充电设备端。
在本发明的实施例中，可以增加可充电设备110的充电系统和充电器120的相互识别功能，利用充电系统来分析可支持的充电电流范围，计算出充电器120可支持的最长和最短充电时长，即充电时长区间；结合用户充电时间需求和充电时长区间的关系，判断后计算选择所需的合适的充电电流值，完成终端设备充电。
图2是根据本发明的另一实施例的充电方法的示意性流程图。图2的方法200由可充电设备执行。包括：
210、向用户呈现指示充电时长区间的信息；
220、接收用户输入的指示目标充电时长的信息，目标充电时长在充电时长区间内；
230、根据目标充电时长确定目标充电电流；
240、利用目标充电电流进行充电。
例如，用户目标充电时长为45min，充电时长区间为30～120min，用户 目标充电时长在充电时长区间之内，则按着用户目标充电时长45min来计算所需充电电流。
应理解，“有效电流区间”可以是指满足可充电设备正常工作的电流区间或范围，也可以是满足外部充电器正常工作的电流区间或范围(例如，当充电器与可充电设备分离的情况下)，也可以是两者的交集。“有效电流区间”或“充电时长区间”中的“区间”指的是该区间的上界和下界，可以包括也可以不包括该区间内的其他值，例如，该区间内的所有的值或者多个离散的值。
还应理解，本发明的实施例可以是适用于可充电设备的恒流充电阶段，也可以适用于其他场景，例如当电池或设备的性能满足恒流充电时。或者，本发明的实施例也可以作为以恒流充电过程来近似估算完整的充电过程或部分充电过程。
本发明的实施例可以通过接收用户输入的充电时长区间中的目标充电时长，再确定目标充电电流，以利用目标充电电流进行充电。由于目标充电时长在充电时长区间中，因此目标充电电流与目标充电时长也是匹配的，从而提高了充电时间的准确度，进而提高了充电效率。
可选地，作为另一实施例，在向用户呈现指示充电时长区间的信息之前，图2的方法还包括：确定可充电设备的有效电流区间；根据有效电流区间，确定充电时长区间。
应理解，文中的“确定可充电设备的有效电流区间”以及“确定充电时长区间”是指确定了区间的上界与下界，可以包括不确定该区间内的其他的值，也可以包括确定该区间内的其他的值。
根据有效电流区间，确定充电时长区间，可以是指：根据有效电流区间的上界以及待充电量确定充电时长区间的下界，根据有效电流区间的下界以及待充电量确定充电时长区间的上界，或者，基于安全等因素的考虑，选择一个余度来确定充电时长区间的上界和下界。
根据本发明的实施例，根据有效电流区间确定充电时长区间，包括：根据待充电量以及有效电流区间的上界和下界，确定最短充电时长和最长充电时长；根据最短充电时长和最长充电时长确定充电时长区间。
应理解，待充电量可以是是用户设定的；也可以是根据用户的相关信息计算的，例如基于用户活动信息进行估算或统计；也可以是默认的。将有效 电流区间与充电时长区间匹配，可以指有效电流区间的值与在充电时长区间中对应的值的乘积为待充电量，也可以大于或小于待充电量，例如，基于安全或电池性能的考虑。
换句换说，最短充电时长和最长充电时长为充电时长区间的上下界。还应理解，在有效电流区间的值与在充电时长区间中对应的值的乘积为待充电量的情况下，当利用最短充电时长时来充电时，可以选择有效电流区间中最大的电流来进行充电，当利用最长充电时长来充电时，可以选择有效电流区间中最小的电流来进行充电。还可以设置对应于标准充电时长的标准充电电流。
由于采用待充电量来匹配有效电流区间和充电时长区间，使得充电过程符合实际的需求，换句话说在充电时长内完成对待充电量的充电，因此能够为用户及时的充电，提升的用户体验。
根据本发明的实施例，待充电量是用户输入的，或基于用户活动信息确定的。
应理解，待充电量是用户输入的：可以是，例如，获取待充电量的选择范围，向用户呈现待充电量的选择界面。也可以呈现用户输入界面，获取用户输入的待充电量的数值。待充电量是基于用户活动信息确定的：分析系统或应用程序中与用户活动或行为相关的时间参数和功耗参数，将该时间段内的能量消耗(时间参数×功耗参数)作为用户目标使用电量。具体地，用户活动信息可以是指：例如，可充电设备系统中用户相关的日程安排、闹铃、会议或约会安排等，可将闹铃时间、日程开始时间、会与和约会开始时间等；或者，电池管理卫士等应用程序可以监控可充电设备的功耗高峰时段，可将功耗高峰时段开始时间；或者，导航软件应用程序，当用户使用车载充电器时，可预先预测用户驾车到达目的地时的时间。应理解，用户活动信息不限于此，还可以包括任何可以估算待充电量的数据或信息。可以是从可充电设备中的程序中获取，也可以是用户设定的。
根据本发明的实施例，有效电流区间为可充电设备的限制电流区间和充电器的限制电流区间的交集。
应理解，标准充电电流和标准充电时长可以按照用户的需求或硬件的性能来自由设置，例如，基于可充电设备的性能或电池的寿命来设置。
由于可以设置标准充电电流和标准充电时长，使得可以在用户没有及时 设置充电时长时来以默认的电流在默认的充电时长内完成充电，从而能够及时的进行充电，又能满足电池寿命等特定的需求。
根据本发明的实施例，向用户呈现指示充电时长区间的信息，包括：向用户呈现指示充电时长区间的数值，以及用于输入目标充电时长的数值的区域；或者向用户呈现指示充电时长区间的第一图形，以及用于基于第一图形选择目标充电时长的第二图形；或者向用户呈现指示充电时长区间的数值，以及语音输入提示。
例如，可以采用图3的A图所示的充电选择界面来选择默认模式、自定义模式或者智能模式中的至少两种。可以是通过窗口的方式来呈现充电时长选择或充电量选择，还可以既选择呈现充电时长又选择充电量。用户通过在每种模式的选项的选择区域点击来进行选择，例如通过手势等。
其中，自定义模式可以是但不限于图3的A图、B图或C图。例如：在图3的B图中，以窗口的方式向用户呈现标准充电时长，和充电时长区间，用户输入的充电时长可以是某一数值。
在图3的C图中，以窗口的方式呈现选择条和在选择条上可以移动的选择块，选择条至少标记有最短充电时长和最长充电时长，选择条还可以标记有标准充电时长。选择块在选择条上的位置指示用户设置的目标充电时长，选择块在选择条上的位置与待选择的充电时长之间的关系可以是线性的，也可以是非线性的。
采用选择的方式输入，可以使得操作更加便捷。采用输入数值的方式，可以保证充电时间的精确性。
在图3的D图中，以窗口的方式呈现选择环，选择环的内外半径差为预设值，选择块在选择环上的位置指示用户设置的目标充电时长，选择环的位置指示预设的待选择的充电时长。
本发明的实施例不限于任何的交互方式以及呈现方式，其中，选择块或滑块可以是任何颜色或图形，呈现窗口可以在终端屏幕的任何位置。语音输入时，可以是任何的语言，并且可以是具有某种含义的语音标识。
可选地，作为另一实施例，图2的方法还包括：
呈现指示充电进度信息的数值或图形，充电进度信息包括剩余充电时间，剩余充电量、充电电压、充电电流、电池容量、电池温度和电池寿命中的至少一种。
例如，可以采用图4所示的用户界面，呈现充电进度，充电参数，电池参数中的至少一项。充电进度可以包括充电完成度、剩余充电时间以及电池荷信息中的至少一项。充电参数可以包括充电电压、充电电流以及以完成充电量中的至少一项。电池参数可以包括电池容量、电池温度以及电池寿命中的至少一项。
应理解，可以通过百分比的方式呈现，例如，数值或图形(柱状、环状或条状图形)。也可是通过非比例数值的方式呈现，例如，“剩余时间10分钟”等。本发明的实施例不限于任何的呈现方式，例如各种图形和颜色的组合。由于采用窗口直观的显示充电信息，使得用户可以实时观看或查看充电的相关参数，因此进一步提高了用户体验。
上图描述了根据本发明实施例的充电方法，下面结合图5来描述根据本发明实施例的可充电设备。
图5是根据本发明的另一实施例的可充电设备的示意性结构图。图5的设备500包括：

接收模块520，接收用户输入的指示目标充电时长的信息，目标充电时长在充电时长区间内；
第一确定模块530，根据目标充电时长确定目标充电电流；
充电模块540，利用目标充电电流进行充电。
本发明的实施例可以通过接收用户输入的充电时长区间中的目标充电时长，再确定目标充电电流，以利用目标充电电流进行充电。由于目标充电时长在充电时长区间中，因此目标充电电流与目标充电时长也是匹配的，从而提高了充电时间的准确度，进而提高了充电效率。
可选地，作为另一实施例，图5的设备还包括：第二确定模块，在向用户呈现指示充电时长区间的信息之前，确定可充电设备的有效电流区间；第三确定模块，根据有效电流区间确定充电时长区间。
根据本发明的实施例，第三确定模块具体用于：根据待充电量以及有效电流区间的上界和下界，确定最短充电时长和最长充电时长；根据最短充电时长和最长充电时长确定充电时长区间。
根据本发明的实施例，待充电量是用户输入的，或基于用户活动信息确定的。
根据本发明的实施例，有效电流区间为可充电设备的限制电流区间和充电器的限制电流区间的交集。
根据本发明的实施例，第一呈现模块具体用于：向用户呈现指示充电时长区间的数值，以及用于输入目标充电时长的数值的区域；或者向用户呈现指示充电时长区间的第一图形，以及用于基于第一图形选择目标充电时长的第二图形；或者向用户呈现指示充电时长区间的数值，以及语音输入提示。
可选地，作为另一实施例，图5的设备还包括：第二呈现模块，呈现指示充电进度信息的数值或图形，充电进度信息包括剩余充电时间，剩余充电量、充电电压、充电电流、电池容量、电池温度和电池寿命中的至少一种。

图6是根据本发明的另一实施例的可充电设备的示意性结构图。图6的可充电设备600包括：处理器610以及存储器620。处理器610通过通信总线调用存储器620中的代码，以实现：向用户呈现指示充电时长区间的信息；接收所述用户输入的指示目标充电时长的信息，所述目标充电时长在所述充电时长区间内；根据所述目标充电时长确定目标充电电流；利用所述目标充电电流进行充电。
本发明的实施例可以通过接收用户输入的充电时长区间中的目标充电时长，再确定目标充电电流，以利用目标充电电流进行充电。由于目标充电时长在充电时长区间中，因此目标充电电流与目标充电时长也是匹配的，从而提高了充电时间的准确度，进而提高了充电效率。
根据本发明的实施例，处理器610还用于在所述向用户呈现指示充电时长区间的信息之前，确定可充电设备的有效电流区间；根据所述有效电流区间，确定所述充电时长区间。

根据本发明的实施例，处理器610还用于呈现指示充电进度信息的数值或图形，所述充电进度信息包括剩余充电时间，剩余充电量、充电电压、充电电流、电池容量、电池温度和电池寿命中的至少一种。
图6的各个模块的操作和功能可以参照图2的描述，此处不作赘述。
在现有技术提供的充电方法中，预设了至少两个电流值，根据用户输入的充电时间，从预设的电流值中选择一个电流值作为充电电流值，使得基于该电流值将电池从剩余电量充电至满电量时所使用的时间不大于目标充电时间，从而对充电速度进行了调整。然而，采用这种方法，用户每次在充电之前须要输入时间，充电的效率仍然低。
本发明的实施例可以通过确定目标使用时刻，再确定充电时间，进而进行充电，因此提高了充电的效率。
图7是根据本发明的另一实施例的充电方法的示意性流程图。图7的方法700由可充电设备执行，包括：
710、确定可充电设备的目标使用时刻；
720、根据目标使用时刻，确定目标充电时长；
730、根据目标充电时长，确定目标充电电流；
740、利用目标充电电流进行充电。
可选地，作为另一实施例，图7的方法还包括：获取用户活动信息；确定可充电设备的目标使用时刻，包括：根据用户活动信息，确定目标使用时刻。
应理解，用户活动信息可以包括获取用户活动的时间信息、可充电设备的使用功耗信息或者用户活动的地点、行为方式等参数。
根据本发明的实施例，获取用户活动信息，包括：获取用户活动的时间信息；或者获取可充电设备的使用功耗信息。
具体地，获取用户活动信息，根据用户活动信息确定目标使用时刻，可以是利用分析系统或应用程序中与用户活动或行为相关的时间参数，将该时间参数确定为用户目标使用时刻。例如可充电设备系统中用户相关的日程安 排、闹铃、会议或约会安排等，可将闹铃时间、日程开始时间、会与和约会开始时间等作为用户目标使用时刻。或者，电池管理卫士等应用程序可以监控可充电设备的功耗高峰时段，可将功耗高峰时段开始时间作为用户目标使用时刻；或者，导航软件应用程序，当用户使用车载充电器时，可预先预测用户驾车到达目的地时的时间，将该时间作为用户目标使用时刻。由于可以采用智能的预测用户的目标使用时刻，可以在不需要用户手动设置的情况下，完成充电过程，极大地方便的用户的使用。
可选地，作为另一实施例，在根据目标使用时刻，确定目标充电时长之前，图7的方法还包括：确定可充电设备的有效电流区间；根据有效电流区间确定充电时长区间；其中，根据目标使用时刻，确定目标充电时长，包括：确定目标使用时刻与当前时刻的时间差值；当时间差值不在充电时长区间内时，根据充电时长区间的上界或下界，确定目标充电时长。
例如，用户目标充电时长为20min，充电时长区间为30～120min，用户目标充电时长在充电时长区间之外，则按着用充电时长区间的下限值30min来计算所需充电电流；若用户目标充电时长为150min，用户目标充电时长在充电时长区间之外，则按着用充电时长区间的上限值120min来计算所需充电电流。根据充电时长区间的上界或下界，确定目标充电时长，还可以不将上界或下界直接确定为目标充电时长，例如，出于对电池寿命等因素的考虑，可以选择与上界或下界相近的值，在本例中，例如35min或115min。
图8是根据本发明的另一实施例的可充电设备的示意性结构图。图8的设备800包括：
第一确定模块810，确定可充电设备的目标使用时刻；
第二确定模块820，根据目标使用时刻，确定目标充电时长；
第三确定模块830，根据目标充电时长，确定目标充电电流；
充电模块840，利用目标充电电流进行充电。
本发明的实施例可以通过确定目标使用时刻，再确定充电时间，进而进行充电，因此提高了充电的效率。
可选地，作为另一实施例，图8的设备还包括：获取模块，获取用户活动信息；第一确定模块具体用于根据用户活动信息确定目标使用时刻。
根据本发明的实施例，获取模块具体用于：获取用户活动的时间信息；或者获取可充电设备的使用功耗信息。
可选地，作为另一实施例，图8的设备还包括：第四确定模块，在根据目标使用时刻，确定目标充电时长之前，确定可充电设备的有效电流区间；根据有效电流区间确定充电时长区间；其中，第三确定模块具体用于：确定目标使用时刻与当前时刻的时间差值；当时间差值不在充电时长区间内时，根据充电时长区间的上界或下界，确定目标充电时长。
图8的各个模块的操作和功能可以参照图7的描述，此处不作赘述。
图9是根据本发明的另一实施例的可充电设备的示意性结构图。图9的可充电设备900包括：处理器910以及存储器920。
处理器910通过通信总线调用存储器920中的代码，以实现：确定可充电设备的目标使用时刻；根据所述目标使用时刻，确定目标充电时长；根据所述目标充电时长，确定目标充电电流；利用所述目标充电电流进行充电。
本发明的实施例可以通过确定目标使用时刻，再确定充电时间，进而进行充电，因此提高了充电的效率。
可选地，作为另一实施例，处理器910还用于：获取用户活动信息；处理器910具体用于根据所述用户活动信息，确定所述目标使用时刻。
根据本发明的实施例，处理器910具体用于：获取用户活动的时间信息；或者获取所述可充电设备的使用功耗信息。
可选地，作为另一实施例，处理器910还用于，在所述根据所述目标使用时刻，确定目标充电时长之前，确定可充电设备的有效电流区间；根据所述有效电流区间确定所述充电时长区间；其中，处理器910具体用于：确定所述目标使用时刻与当前时刻的时间差值；当所述时间差值不在所述充电时长区间内时，根据所述充电时长区间的上界或下界，确定所述目标充电时长。
