具体实施方式
下面将结合附图，对本发明实施例中的技术方案进行描述。显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。
在本说明书的描述中“一个实施例”或“一些实施例”等意味着在本申请的一个或多个实施例中包括结合该实施例描述的特定特征、结构或特点。由此，在本说明书中的不同之处出现的语句“在一个实施例中”、“在一些实施例中”、“在其他一些实施例中”、“在另外一些实施例中”等不是必然都参考相同的实施例，而是意味着“一个或多个但不是所有的实施例”，除非是以其他方式另外特别强调。
其中，在本说明书的描述中，除非另有说明，“/”表示或的意思，例如，A/B可以表示A或B；本文中的“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，在本申请实施例的描述中，“多个”是指两个或多于两个。
在本说明书的描述中，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。术语“包括”、“包含”、“具有”及它们的变形都意味着“包括但不限于”，除非是以其他方式另外特别强调。
一种充电控制策略为离散控制策略。通过监控移动终端内部的测温点的温度，当测温点 的实际温度低于该测温点的限流温度阈值后，采用充电电流上限对充电电流进行限制。一般情况下，会设置多个电流上限值以及各电流上限值对应的限流温度阈值，以对充电电流进行阶梯式控制。同时，为了防止温度在限流温度阈值附近上下变动而导致充电电流大幅波动，为电流上限值设置有退出温度阈值。该退出温度阈值低于该电流上限值对应的限制温度阈值。可以将电流上限值的退出温度阈值和该电流上限值的限流温度阈值之间的温度间隔，称为限流温区。当测温点的实际温度低于退出温度阈值时，才退出该电流上限值对充电电流的限制。在某些场景下，通常存在测温点的实际温度长时间滞留在限流温区中，导致不能采用较高的充电电流，过度限制充电速度。
图1示出了一种离散控制策略。如图1所示，当器件A实际温度小于44℃时，电流上限值为8A；当器件A实际温度大于44℃时，电流上限值为5A。为了防止器件A实际温度在44℃波动导致的充电电流波动，设置了41-44℃限流温区，只有在器件A实际温度低于41℃时，才将充电电流的电流上限值从5A调整为8A。若器件A发生短时高功耗，使得器件A的实际温度大于44℃，而采用5A对充电电流进行限制。在此情况下，只有器件A实际温度低于41℃时，充电电流的电流上限值才会从5A调整为8A。通常，器件A降温的过程很缓慢，从44℃降到41℃需要花费较长时间。而在期间中，充电电流的电流上限值为5A，这降低了充电速度，使得用户充电体验较差。
一种充电控制策略为采用恒定的目标温度，通过比例积分微分(proportional integral differential，PID)控制器，连续控制充电电流，使充电芯片(charge IC)的实际温度保持在该恒定的目标温度上下波动。
该充电控制策略仅考虑充电芯片温度，未能全面反映移动终端的发热情况。在有些场景下，充电芯片之外的其他高功耗器件的温度较高，也使得移动终端局部温度较高，严重影响用户的充电热体验。例如，手机在进行后台下载任务、编译应用程序任务或游戏任务时，片上系统(system on chip，SoC)芯片功耗较高，相应地，温度也较高。再例如，手机信号较差时，调制解调器的功率放大器(power amplifier，PA)功耗较高，相应地，温度也较高，上述两种情况都有可能造成移动终端局部过热。
该充电控制策略跟踪的限流温度恒定，如果限流温度设置较高，则影响用户充电热体验。如果限流温度设置较低，影响用户充电速度体验，很可能导致充电速度慢甚至电量越充越小。例如在游戏场景下，移动终端SoC芯片等器件功耗较高，发热较大，由于热传递效应，使得充电芯片的温度也较高，而充电控制策略为了使充电芯片的实际温度维持在限流温度而将充电电流降到很小，甚至可能导致断充，严重影响用户的充电速度体验。

电子设备可以根据任意充电场景下的任意温控器件对应的温度-电流关系，生成温度电流曲线，如此可得到该任意充电场景下的各个温控器件对应的温度电流曲线，以及得到各个充电场景各自的各个温控器件对应的温度电流曲线。任意温控器件的温度电流曲线可以理解为描述电子设备的充电电流和该温控器件的限流温度的对应关系的一种方式。当确定了电子设备的充电电流时，可以通过温度电流曲线，确定温控器件在该充电电流下对应的限流温度。如此，可以通过配置的离散的限流温度和充电电流的对应关系，可以得到连续的限流温度和充电电流的对应关系的描述方式，进而可以确定温控器件在不同充电电流下对应的不同限流温度，实现对充电电流的连续调整。
在一些实施例中，温度电流曲线可以为二维坐标系上的曲线，其中，曲线中各点的斜率连续变化。温度电流曲线可以为二维坐标系上的折线，该折线可以多条直线段依次相接组成，其中相邻的直线段的斜率不同。温度电流曲线也可以为二维坐标系上的曲线和直线段的混合线段，其中，曲线可以位于处于两条直线段之间。该两个直线段的斜率可以不同，也可以相同。
在一个说明性示例中，对于任意充电场景下的任意温控器件，可以将其温度-电流关系通过二维坐标表示，进行拟合或者连接相邻两个坐标点，得到该充电场景下的该温控器件的温度电流曲线。
在一个例子中，预先配置多个限流温度和充电电流的对应关系，如此，可以在二维坐标系上得到多个的坐标点，通过连接相邻两个坐标点，可以得到多个首尾相接的线段组成的折线。当坐标点较多或者说坐标点较为密集时，得到的折线可以近似于曲线。在一个说明性示例中，该二维坐标系的自变量(X轴)可以为电流，因变量(Y轴)可以为温度。
示例性的，可以将同一充电场景下的各温控器件的温度电流曲线在一个图中表示，即各温控器件的温度电流曲线对应于同一图中的不同折线或曲线。在一个例子中，可以设定充电场景为场景B，场景B下的温控器件为器件B1和器件B2。场景B的温度电流曲线可以如图4A所示。在一个例子中，可以设定充电场景为场景C，场景C下的温控器件为器件C1和器件C2。场景B的温度电流曲线可以如图4B所示。

示例性的，任意场景下的任意温控器件的温度电流曲线可以为折线，也可以为曲线。在一个例子中，以充电场景为灭屏场景为例，灭屏场景下的温控器件为PA和充电芯片。PA的 温度电流曲线和充电芯片的温度电流曲线可以如图6A和图6B所示的折线表示，也可以如图7A和图7B所示的曲线表示。
在一个说明性示例中，在温控器件的温度电流曲线为曲线时，可以控制温度电流曲线的斜率(曲线上各点的切线斜率)变化，来确定该温度电流曲线对应的充电策略。以温度电流曲线的自变量(X轴)可以为电流，因变量(Y轴)可以为温度为例，若随着电流的增大，温度电流曲线的斜率由小到大，使得温度电流曲线呈现为下凹曲线。在这种情况下，充电策略为倾向于抑制充电速度、保持电子设备低温。随着电流的增大，温度电流曲线的斜率的由大到小，使得温度电流曲线呈现为上凸曲线。在这种情况下，充电策略为倾向于加快充电速度。
更具体的，以图7A所示的灭屏场景下PA的温度电流曲线为例，随着电流的增大，温度电流曲线的斜率由小到大，使得温度电流曲线呈现为下凹曲线。在这种情况下，充电策略为倾向于抑制充电速度、保持电子设备低温。
再以图7B所示的灭屏场景下充电芯片的温度电流曲线为例，随着电流的增大，温度电流的增大，温度电流曲线的斜率的由大到小，使得温度电流曲线呈现为上凸曲线。在这种情况下，充电策略为倾向于加快充电速度。在一个例子中，如上所述，可以通过预先配置较多个多个限流温度和充电电流的对应关系，得到近似于曲线的折线。因此，可以预先配置足够多的限流温度和充电电流的对应关系，得到近似于上凸曲线的折线(上凸曲线)或近似于下凹曲线的折线(下凹曲线)。
在一个说明性示例中，用于表示温控器件的二维坐标系的自变量(X轴)可以为温度，因变量(Y轴)可以为电流。在该示例中，同一充电场景下的各温控器件的温度电流曲线的表示方式、温度电流曲线为曲线时的斜率的变化等可以参考上述示例所述，在此不再赘述。
通过上述方式，可以生成任意充电场景下各温控器件的温度电流曲线。电子设备可以根据任意充电场景下的任意温控器件的温度电流曲线，确定该温控器件在任意充电电流下对应的限流温度。容易理解，任意温度电流曲线具有其描述方式。示例性的，描述方式可以为以充电电流为自变量，限流温度为因变量的函数，例如，可以设定在充电电流处于预设电流区间时，温度电流曲线的描述方式为y＝f(x)，其中，y表示限流温度，x表示充电电流。电子设备根据温度电流曲线确定限流温度，具体可以为根据温度电流曲线的描述方式，确定限流温度。
在一些实施例中，电子设备可以预先生成各个充电场景下各个温控器件的温度电流曲线，并记录(具体可以记录温度电流曲线的描述方式(函数等))，以方便在后续步骤中，根据确定的充电场景，选择该充电场景下各个温控器件的温度电流曲线，以确定该场景下各个温控器件各自的限流温度。
在一些实施例中，电子设备可以识别当前使用场景，并获取该当前使用场景下的各个温控器件对应的温度-电流关系，进而生成当前使用场景下的各个温控器件对应的电流线性关系图，以便确定当前使用场景下各个目标器件各自的限流温度。
接下来，在不同实施例中，举例介绍确定充电场景的方案。
在一些实施例中，可以预先将充电场景和应用类型进行关联，例如游戏场景和游戏类应用关联，视频播放应用和视频播放场景关联。在一个例子中，可以设置使用场景关联名单，该使用场景关联名单包括多个应用，其中每个应用关联有充电场景。
在实施时，电子设备可以检测当前前台运行应用，并确定前台运行应用所属的应用类型。例如，可以检测当前前台运行应用的包名(package name)，并根据当前前台运行应用的包名， 确定当前前台运行应用所属的应用类型，进而可以确定当前使用场景。如当前没有前台运行应用，则确定当前使用场景为灭屏场景。
在一些实施例中，可以预先训练充电场景识别模型。在一个例子中，以电子设备的多个场景下的温控器件的功耗值为训练样本，该训练样本带有场景标签，以进行有监督训练，以得到场景识别模型。具体的，每个训练样本的输入可以是1个多维向量，对于任意多维向量，其维数为器件的个数，该向量中每个元素为一个器件的功耗值。每个训练样本的输出是场景标签(游戏场景、视频通话场景、灭屏场景等)，通过有监督训练，可以得到场景识别模型。其中，训练样本中的功耗值可以为瞬时功耗，也可以为一时间段内的平均功耗值，例如0.5秒时长的平均功耗。在一个例子中，功耗值的单位可以为mW，也可以为mA。其中，当功耗值为mA时，需要通过3.8V电压对各器件功耗进行归一化。
电子设备可以获取多个器件的功耗值，将多个器件的功耗值输入到场景识别模型进行场景识别。该场景识别模型可以输出识别出的当前终端使用场景，从而可以确定温控器件以及温度电流曲线。输入的功耗值可以为瞬时功耗，也可以为一时间段内的平均功耗值，例如0.5秒时长的平均功耗。
在具体实现时，通过前台运行应用确定充电场景和通过充电场景识别模型确定充电场景可以各自独立使用，也可以配合使用。例如，当前台运行应用不在使用场景关联名单上时，可以通过充电场景识别模型确定充电场景。
在一些实施例中，在电子设备充电时，电子设备可以确定其电池的剩余电量，并根据电子的剩余电流确定电子设备的使用场景。示例性的，若电池的剩余电量较少(例如低于20％)，可以确定电子设备的使用场景为预设的使用场景S1。若电池的剩余电量较多(例如高于80％)，可以确定电子设备的使用场景为预设的使用场景S2。在一个例子中，使用场景S1可以对应有预设的温度电流函数H1，以及温控器件Q1(例如可以为SoC芯片、充电芯片等)，使用场景S2可以对应有预设的温度电流函数H2，以及温控器件Q1。对于温控器件Q1，在相同的充电电流下，通过温度电流函数H1得到的限流温度大于通过温度电流函数H2得到的限流温度。在一个例子中，使用场景S1可以为上述充电速度较快的使用场景，例如灭屏场景。使用场景S2可以为上述充电速度较慢的使用场景，例如游戏场景。在该例子中，在电池的剩余电流较低或较高时，可以不考虑或忽略通过前台运行应用或通过器件功耗确定出的使用场景，而是以通过电池的剩余电流确定出的使用场景为准，从而可以在电池的剩余电量较低时，提高用户的充电速度体验，以及在电池的剩余电量较高时，提高用户的充电热体验。
需要说明的是。上述示例仅为举例说明，不构成限定。在实现时，可以根据经验设定电池的剩余电量和使用场景的对应关系，以及使用场景对应的温度电流函数和温控器件。
在一些实施例中，电子设备可以确定电子设备所在外部环境的温度，例如可以电子设备的外表面或者接近外表面处可设置有温度传感器，该温度传感器可以用于检测电子设备所在外部环境的温度。示例性的，电子设备外部环境的温度较低(例如低于10℃)，可以确定电子设备的使用场景为预设的使用场景S3。若电子设备外部环境的温度较高(例如高于30℃)，可以确定电子设备的使用场景为预设的使用场景S4。在一个例子中，使用场景S3可以对应有预设的温度电流函数H3，以及温控器件Q2(例如可以为SoC芯片、充电芯片等)，使用场景S4可以对应有预设的温度电流函数H4，以及温控器件Q2。对于温控器件Q2，在相同的充电电流下，通过温度电流函数H3得到的限流温度大于通过温度电流函数H4得到的限流温度。在一个例子中，使用场景S3可以为上述充电速度较快的使用场景，例如灭屏场景。使用场景S4可以为上述充电速度较慢的使用场景，例如游戏场景。在该例子中，在电子设备的外 部环境温度较低或较高时，可以不考虑或忽略通过前台运行应用或通过器件功耗确定出的使用场景，而是以通过外部环境温度确定出的使用场景为准，从而可以在外部环境温度较低时，提高用户的充电速度体验，以及在外部环境温度较高时，提高用户的充电热体验。
需要说明的是。上述示例仅为举例说明，不构成限定。在实现时，可以根据经验设定外部环境温度和使用场景的对应关系，以及使用场景对应的温度电流函数和温控器件。
在一些实施例中，在电子设备充电时，电子设备可以显示使用场景选择界面。使用场景选择界面可以包括多种使用场景。用户可以从多种使用场景中选择一种使用场景，电子设备可以将用户选择的场景确定为电子设备的使用场景。具体而言，电子设备可以响应用户起始的使用场景选择操作，确定电子设备的使用场景。
在本申请实施例提供的充电控制方法中，还需要获取温控器件的实测温度。接下来，举例介绍各个器件实测温度的获取方案。
在一些实施例中，可以在器件内部设置测温点，或者在器件外部(例如相距器件5mm-10mm处)设置测温点。测温点设置有温度传感器。温度传感器具体可以为热敏电阻(thermistors)，例如负温度系数(negative temperature coefficient，NTC)热敏电阻、正温度系数(positive temperature coefficient，PTC)热敏电阻等。可以将器件的测温点检测到的温度作为该器件的实测温度。在一个例子中，可以将测温点检测到的瞬时温度作为对应器件的实测温度。在一个例子中，可以将测温点在一时间段内(例如0.5秒时长的时间段)内检测到的温度的平均值，作为对应器件的实测温度。
在一个说明性示例中，虽然，SoC芯片内部通常设置有测温点，但由于SoC芯片内部的温度变动较为剧烈。在本示例中，可以不采用SoC芯片测温点检测到的温度，而是将SoC芯片外部的测温点(例如，设置在主板上，与SoC芯片之间的距离在5mm-10mm之间的测温点)检测到的温度，作为SoC芯片的实测温度。
在一些实施例中，若电子设备的某个或某些器件不宜设置测温点，例如，由于空间限制或所在电子设备中的位置限制或电磁干扰等因素，有些器件内部以及附近不宜放置热敏电阻。而这些器件的温度较高，可以影响用户充电的热度体验。针对前述情况，可以采用仿真加拟合的方法，模拟这些器件的温度。具体可以为采用有限元仿真和线性回归的方法，首先通过有限元热仿真，模拟电子设备内部温度分布情况，产生多个训练数据。每个训练数据的输入为各个具有测温点的器件的温度值(该器件的测温点检测到的温度)，输出为所要模拟的器件的温度；之后通过线性回归，得出通过测温点检测到的温度，进而可以计算所要模拟的器件的温度值。接下来，举例介绍待调温差的确定方案。
在确定了当前使用场景时或之后，可以确定该充电场景下的各个温控器件的温度电流曲线。可以获取当前充电电流I1。通过当前使用场景下的各个温控器件的温度电流曲线，分别确定该各个温控器件在当前充电电流I1下的限流温度。
在一些实施例中，还可以获取该各个温控器件的实测温度。可根据各个温控器件在当前充电电流I1下的限流温度，和各个温控器件的实测温度，分别确定各个温控器件的待调温差。
在一个例子中，对于任一温控器件，可以将该温控器件的在当前充电电流I1下的限流温度减去该温控器件的实测温度，得到该温控器件的待调温差。
在一个例子中，对于任一温控器件，可以将该温控器件的在当前充电电流I1下的限流温度乘以预设系数J1后，减去该温控器件的实测温度，得到该温控器件的待调温差。
在一个例子中，对于任一温控器件，可以将该温控器件的实测温度乘以预设系数J2，得到加权实测温度。可以将该温控器件在当前充电电流I1下的限流温度，减去该加权实测温度， 得到该温控器件的待调温差。
在一些实施例中，可以根据各个温控器件的待调温差，确定目标器件，以便根据目标器件的待调温差确定充电电流的上限值，即确定电流上限值。
在一说明性示例中，可以从各个温控器件对应的待调温差中确定最小待调温差。
示例性的，参阅图8A和图8B，可以设定当前使用场景的温控器件为器件W1和器件W2，当前充电电流为6A(i＝6A)，器件W1的实测温度为44℃(T A＝44℃)，器件W2的实测温度为42℃(T B＝42℃)。
通过器件W1的温度电流曲线，可确定器件W1在充电电流为6A下的限流温度为44.5℃(T target_W1(i)＝44.5℃)。器件W1的待调温差ΔT A＝T target_A(i)–T A＝0.5℃。
通过器件W2的温度电流曲线，可确定器件W2在充电电流为6A下的限流温度为44℃(T target_W2(i)＝44℃)。器件W2的待调温差ΔT B＝T target_B(i)–T B＝2℃。
ΔT A小于ΔT B，即为ΔT A最小待调温差。
可以将最小待调温差对应的器件作为目标器件。目标器件的待调温差，即最小待调温差可以用于确定充电电流调整的电流上限值。通过利用当前使用场景下各温控器件的待调温差中最小待调温差，确定调整充电电流的电流上限值，可以保证在使用确定得到的电流上限值调整的充电电流进行充电时，各温控器件的实测温度不会超过各自对应的限流温度，从而可以保证用户充电的热度体验。
在一个说明性示例中，当当前使用场景的温控器件包括三个器件或更多个器件时，可以将该三个器件或更多个器件中的待调温差较小的两个或更多个器件作为目标器件。可以根据两个或更多个器件的待调温差，确定充电电流调整的电流上限值。示例性的，可以计算该两个或更多个器件的待调温差的平均温差。该平均温差可以为加权平均温度，例如，两个或更多个器件中待调温差越小的器件具有的权重越大。该平均温差可以用于确定充电电流调整的电流上限值。
在一些实施例中，可以将当前使用场景的各个温控器件作为目标器件。可以计算各个温控器件的待调温差的平均温差。该平均温差可以为加权平均温差，例如，各个器件中待调温差越小的器件具有的权重越大。该平均温差可以用于确定充电电流调整的电流上限值。
在一些实施例中，可以将各个温控器件的在当前充电电流I1下的限流温度进行比较，确定出最小限流温度，并将最小限流温度对应的温控器件作为目标器件，该目标器件对应的待调温差可以用于确定电流上限值。
接下来，举例介绍确定电流上限值的方案。
电子设备可以按照调控周期，周期性执行本申请实施例提供的充电控制方法，以周期性确定调整充电电流的电流上限值，对充电电流进行周期性调控。在一个例子中，每一调控周期的时长为0.5秒。在一个例子中，每一调控周期的时长可以为1秒。等等，此次不再一一列举。
在一些实施例中，在任意调控周期中，可以采用PID算法，根据上文确定的目标器件的待调温差或平均温差，确定充电电流调整的电流上限值。
