具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的实施例仅用以解释本申请，并不用于限定本申请。
在本申请实施例的描述中，如果有描述到“第一”、“第二”等只是用于区分技术特征为目的，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或者隐含指明所指示的技术特征的先后关系。“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，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的情况。其中A，B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项”及其类似表达，是指的这些项中的任意组合，包括单项或复数项的任意组合。例如，a，b和c中的至少一项可以表示：a，b，c，a和b，a和c，b和c或a和b和c，其中a，b，c可以是单个，也可以是多个。
此外，下面所描述的本申请各个实施方式中所涉及到的技术特征只要彼此之间未构成冲突就可以相互组合。
本申请实施例涉及的充电控制方法，是基于可编程电源协议(Programmable Power Supply，PPS),为了适应不同终端在不同的应用场景下的充电需求，需要对充电器的输出功率进行调整，以达到电池保护、终端温度控制等功能。而在实际应用中，随着充电器性能的不断提升、终端的单个部件功耗值日渐增高，终端性能和充电效率对充电控制提出了更高的要求。因此，采用科学合理的充电控制的方式能更加有效地在充电状态下发挥终端的性能，尤其是在终端处于高负载运作的情况下，既能保证终端性能得到充分的发挥，也能有效提高终端的充电效率。示例性的，充电控制的经典场景为：在终端电池电量很低的情况下，还需 要继续高强度地使用终端，必须插上充电器维持电量。在这种高功耗充电场景下，往往会发生因充电升温和高负载升温叠加而导致的终端快速发热现象。
为了保证终端充电的安全性，现有的常规充电控制方法为：在充电时主要是根据电池的温度和电量等因素，计算得到电池需要的充电电流，再根据电池的这个充电需求来设置充电器的输出电流进行充电。这种控制方法的问题在于当系统负载较大的时候，处理器的发热和充电的发热叠加，会导致系统整体温度迅速上升。而温度上升后一般会触发各种保护性的动作来达到降温的目的，比如降低CPU主频、降低LCD亮度、降低充电电流等，而这些保护动作会严重地限制了终端的性能，影响用户体验。
而为了保证手机在充电状态下的性能，部分手机厂商在解决低电量高负载使用时的充电发热的问题上，提供了一种充电分离的控制模式。在打开该模式的情况下，插上充电器后，充电器完全不给电池充电而只提供系统消耗，这种方法在保证手机性能的前提下确实能实现对电池的温控。但这种方案的问题在于在高负载下，由于电池一直无法进行充电，充电器无法使电池电量得到增长，电池处于低电量状态导致损坏；另外，由于用户在使用终端时无法离开充电器使用，给用户带来诸多不便。
基于以上，本申请实施例提供一种充电控制方法、装置、电子设备及计算机可读存储介质，根据电池的温控充电电流值，确定电池的充电需求功率；根据系统功耗值和充电需求功率，确定充电参数；根据充电参数确定充电器的充电输出功率，以使充电器按照充电输出功率对终端充电，以实现有效缓解高负载运行状态下系统供电和电池充电之间的矛盾，保持对终端的稳定供电和温度控制，在确保用户的使用体验的前提下保证终端的充电稳定性。
请参见图1，图1示出了本申请实施例提供的一种充电控制方法的流程。如图1所示，本申请实施例的充电控制方法包括以下步骤：
S1000，获取终端的系统功耗值。
通过现有的终端检测软件，能直接获取各个主要部件的功耗值，将终端的主要耗电部件的功耗值进行定期的收集和统计，就能合并得出终端的系统功耗值。通过检测软件获取终端各个部件的功耗值属于现有技术，此处不再赘述。
示例性的，移动终端的主要部件包括显示屏、CPU、传感器、摄像头、扬声器等。其中，显示屏在工作过程中发热发亮，尤其是目前的移动终端显示屏的分辨率绝大部分都在1080P以上，在长时间的使用过程中会耗费大量的电量。另外，移动终端的所有操作都受CPU控制，CPU的性能指标直接决定了移动终端的系统性能指标。CPU具有以下几个方面的基本功能：数据通信，资源共享，分布式处理和提供系统可靠性，因此，在正常使用手机的情况下显示屏和CPU是最耗电的移动终端部件。当然，在某些特定场景下，其他部件的耗电量也能占据移动终端大部分的系统功耗值。示例性的，在长时间使用摄像头进行拍摄，长时间使用扬声器进行音乐外放等情况下，摄像头和扬声器等成为电量消耗的主要部件。计算其功耗值的总和，就能获取终端的系统功耗值。
在实际应用中，为了便于实时计算终端的系统功耗值，终端的系统功耗值能用充电器的输入功率减去电池的实际充电功率得到，其计算公式如下所示：
P sys＝U in*I in-U bat*I bat
其中，P sys为终端的系统功耗值，U in为充电器的输入电压值，I in为充电器的输入电流值，U bat为电池的输入电压值，I bat为电池充电电流。
S2000，确定终端通过充电器充电且处于高负载工作状态，根据电池的温控充电电流值，确定电池的充电需求功率；根据系统功耗值和充电需求功率，确定充电参数，其中，温控充电电流值为电池在充电不发热情况下的最大电流值。
请参见图2和图3，图2和图3均示出了上述步骤S2000的一种实现过程示意图。如图2和图3所示，步骤S2000至少包括以下步骤：
S2100，确定终端通过充电器充电。
终端能通过检测充电接口的输入电压值和输入电流值，判断终端是否经过充电器与电源连通。示例性的，终端能通过充电芯片采集电池的状态判断电池是否通过充电器进行充电，比如电池是否存在充电电压或者充电电流，以及电池的电量是否处于增长状态，进而判断终端通过充电器与电源连接，充电器对终端的部件提供供电，并通过充电芯片对电池进行充电。
S2200，确定终端处于高负载工作状态，根据电池的温控充电电流值，确定电池的充电需求功率。
请参见图4，图4示出了上述步骤S2200的一种实现过程示意图。如图4所示，步骤S2200至少包括以下步骤：
S2210，确定终端处于高负载工作状态。
高负载工作状态是指终端处于因主要部件的资源占用率高而处于高能耗状态。示例性的，移动终端在运行多个应用程序，或者运行占用大量CPU和内存资源的程序时，如大型游戏、照相机、图象处理软件等，移动终端处于能耗高、发热量大的状态。当终端处于高负载工作状态时，为了避免核心部件因温度过高发生损坏，一般都设置有保护机制，如开启散热部件、限制CPU输出性能、降低显示屏亮度、强行关机等，以把终端的温度控制在安全范围内。
请参见图5，图5示出了上述步骤S2210的一种实现过程示意图。如图5所示，步骤S2210至少包括以下步骤：
S2211，比较系统功耗值与功率阈值。
功率阈值为预设值，其数值大小反映出当前终端处于高负载工作状态。因此，针对不同的硬件配置、软件配置和运行环境的终端，其功率阈值需要进行调整和匹配，以便于功率阈值能准确地表征终端的运行状态。示例性的，移动终端的功率阈值设置为8W，在终端通过充电器充电的情况下，当前的系统功耗值大于8W时，即确定移动终端处于高负载工作状态。
S2216，判定终端处于高负载工作状态。
在系统功耗值大于功率阈值的情况下，即充电器的输入功率减去电池的实际充电功率终端大于功率阈值，这是因为终端的主要部件处于高能耗状态而导致系统功耗值占用充电器的输入功率的比例增大，进而确定终端处于高负载工作状态。
另一个实施例中，步骤S2210至少包括以下步骤：
S2212，获取终端的处理器占用率。
处理器占用率是终端运行的程序占用的处理器资源,表示终端在某个时间点的运行程序的情况。处理器占用率越高,说明终端在这个时间上运行了很多程序,反之较少。因此，处理器占用率的大小能直接反映出终端的运行状态。通过现有的终端检测软件，能定期、准确地获取处理器占用率，进而及时地判断出当前终端的运行情况。
S2213，比较终端的处理器占用率与占用率阈值。
占用率阈值同样为预设值，其数值大小反映出当前终端处于高负载工作状态。因此，针 对不同的硬件配置、软件配置和运行环境的终端，其占用率阈值需要进行调整和匹配，以便于占用率阈值能准确地表征终端的运行状态。示例性的，移动终端的占用率阈值设置为30％，在终端通过充电器充电的情况下，当前终端的处理器占用率大于30％时，即确定移动终端处于高负载工作状态。
S2216，判定终端处于高负载工作状态。
在终端的处理器占用率大于占用率阈值的情况下，即处理器处于高能耗运行状态。示例性的，移动终端的所有操作都受处理器控制，处理器的性能指标直接决定了移动终端的系统性能指标。因此，在终端的处理器占用率大于30％的情况下，表明处理器及其他核心部件均处于高能耗状态，进而确定终端处于高负载工作状态。
另一个实施例中，步骤S2210至少包括以下步骤：
S2214，获取终端的显示屏持续显示时长。
终端的显示屏持续显示时长是终端运行的显示屏连续处于工作状态的时间,表示终端在该时间段内处于工作状态。尤其是随着高刷新率的LCD屏幕普及，移动终端中显示屏的能耗占比越发提高。终端的显示屏持续显示时长越大,说明终端在这个时间段内持续运行并消耗功率。因此，显示屏持续显示时长的大小能直接反映出终端的运行状态。通过现有的终端检测软件，能实时地获取显示屏持续显示时长，进而及时地判断出当前终端的运行情况。
S2215，比较终端的显示屏持续显示时长与时间阈值。
时间阈值同样为预设值，其数值大小反映出当前终端处于高负载工作状态。因此，针对不同分辨率的显示屏和运行环境的终端，其时间阈值需要进行调整和匹配，以便于时间阈值能准确地表征终端的运行状态。示例性的，移动终端的时间阈值设置为30分钟，在终端通过充电器充电的情况下，当前终端的显示屏持续显示时长大于30分钟时，即确定移动终端处于高负载工作状态。
S2216，判定终端处于高负载工作状态。
在终端的显示屏持续显示时长大于时间阈值的情况下，即终端的显示屏长时间处于运行状态。示例性的，移动终端的显示屏的能耗占据终端的系统功耗值相当的比例，因此显示屏的连续工作时长直接决定了移动终端的能耗值。因此，在显示屏持续显示时长大于30分钟的情况下，表明显示屏和移动终端均处于高能耗状态，进而确定终端处于高负载工作状态。
在实际应用中，为了提高对终端是否处于高负载工作状态判断的时效性和精准性，可以对上述步骤S2211、步骤S2213和步骤S2215一个或多个不同条件进行组合判断，即至少满足中系统功耗值大于功率阈值、终端的处理器占用率大于占用率阈值、终端的显示屏持续显示时长大于时间阈值中至少一个条件，才能确认终端处于高负载工作状态。
除了步骤S2210中系统功耗值、终端的处理器占用率和终端的显示屏持续显示时长作为确定终端是否处于高负载工作状态的判断依据外，终端的其他运行参数也能作为判断依据。示例性的，终端的运行内存占用率、终端的CPU当前温度等运行参数也能作为参考指标，用于判断终端是否处于高负载工作状态，其判断过程与上述步骤S2210一致，此处不再赘述。
S2220，获取最大电流值。
请参见图6，图6示出了上述步骤S2220的一种实现过程示意图。如图6所示，步骤S2220至少包括以下步骤：
S2221，在恒温环境下，以不同的额定充电电流对电池进行充电，并确保在预设时间内电 池的温度增长值小于温度阈值。
由于电池的性能相对稳定，在输入某个特定的充电电流情况下，电池的温度增长值能控制在一定范围内，进而在保证电池的充电效率的前期下，能有效地减少电池的温度上涨，避免电池在充电过程中温度增长过快，对终端的其他部件带来影响。
为了保证额定充电电流对电池的温度的影响，最大电流值的获取过程需要在温度恒定的环境下进行，比如，在恒温实验室内进行充电测试。示例性的，在恒温实验室内，当前室温设置为25摄氏度，预设时间为30分钟，温度阈值为1摄氏度。以额定充电电流I test对电池充电30分钟，并对电池温度值进行采集和统计。如果30分钟内电池温度上升小于1摄氏度，则将当前I test的电流值记录，并作为温控充电电流值的参考值。提高额定充电电流，重复上述的充电过程，记录多个符合温控条件的额定充电电流I test。
S2222，从不同的额定充电电流中选取最大值作为电池在充电不发热情况下的最大电流值。
从多个符合温控条件的额定充电电流I test中，选取最大值I max作为温控充电电流值。即当电池的充电电流为I max时，在保证电池的充电效率的前提下，电池的温度增长值小于温度阈值，使电池的温度控制在一定范围内，避免发生电池和终端在充电过程中发生温度过高的情况，影响电池的安全性和终端的性能。
S2230，根据温控充电电流值和电池的输入电压值，确定充电需求功率。
在充电过程中，由于电池的输入电压值U bat随着充电器的输入电压值U in和终端的系统功耗值P sys的改变而改变，因此需要根据当前电池的输入电压值U bat和温控充电电流值，计算出当前充电需求功率，其计算公式如下所示：
P bat＝U bat*I max
其中，P bat为当前充电需求功率，I max电池的温控充电电流值。
S2300，确定终端处于低负载工作状态，根据电池的技术参数和当前电量，获得充电需求功率。
低负载工作状态指终端处于因主要部件的资源占用率不高而处于低能耗状态。确定终端处于低负载工作状态的过程可以参照上述步骤S2210，当终端不满足上述高负载工作状态的条件，即可确定终端处于低负载工作状态。示例性的，当系统功耗值小于功率阈值、终端的处理器占用率大于占用率阈值、终端的显示屏持续显示时长小于时间阈值时，即可判定终端处于低负载工作状态。
当终端处于低负载工作状态时，由于系统功耗值较小，只消耗少部分充电器的总输出功率。因此，在这种情况下，充电器能充分满足电池的充电需求，根据电池的需求、性能和当前电量，对电池提供足够的充电电流和充电电压。示例性的，终端的电池能支持20W快充，则根据电池状态计算对充电器的功率需求，根据电池的规格书和当前电池的情况，计算电池允许的最大充电功率20W，作为对充电器的输出功率需求，并不需要考虑系统的功耗情况。此时，当前充电需求功率P bat的计算公式如下所示：
P bat＝P max
其中，P max为当前电池允许的最大充电功率。
通过电池的规格和当前电池充电情况，比如电池的种类、容量、电池当前电量、电池的温度等等，获取电池当前理想的电池的输入电压值U bat和电池充电电流I bat，进而使充电器动 态调整输出功率，满足电池的充电需求，属于现有的充电控制技术，此处不再赘述。
S2400，根据系统功耗值和充电需求功率，确定充电参数。
请参见图7，图7示出了上述步骤S2400的一种实现过程示意图。如图7所示，步骤S2400至少包括以下步骤：
S2410，根据系统功耗值和充电需求功率确定总输出功率。
充电器连接终端并对其进行充电的过程中，充电器输出一部分功率对终端的外设进行供电，另外一部分则通过充电芯片对电池进行充电。因此，在获取的系统功耗值和充电需求功率的情况下，即能计算出总输出功率P total，其计算公式如下所示：
P total＝P sys+P bat
通过系统功耗值和充电需求功率相加得到总输出功率，能保证充电器提供终端系统所需要的电能，也能向电池输出稳定的充电功率，既能避免终端因供电不足和发热过快导致的性能受限，也保证了电池的充电效率。
S2420，根据电池的输入电压值确定充电器输出电压。
电池的标称电压是指其正常使用，即处于放电状态时，能够维持较长时间的电压值。而当电池处于充电状态时，由于其内阻的作用，使得电池的输入电压值U bat升高。因此，在一般情况下，输入电压值U bat比电池的标称电压高20％左右。另外，根据终端电池的实际测试数据，由于充电器的输出端分别与终端外设和电池相连，因此充电器输出电压为电池的标称电压的两倍以上，才能保证输入电压值U bat比电池的标称电压高20％，电池才能分配到足够的充电功率，并使电池的充电效率达到最佳。因此，能根据电池性能参数和电池的输入电压值U bat，计算出充电器输出电压。示例性的，当前电池的输入电压值与标称电压均为4V时，则把充电器输出电压设置为9V，以确保电池能分配到足够的充电功率，保证电池的充电效率。
在充电参数的确定过程中，为了确保电池能处于理想的充电状态，应优先满足电池的电压需求，以保证电池的输入电压值U bat比电池的标称电压高20％。然后，再根据充电需求满足电池的输入电流。
S2430，根据总输出功率和充电器输出电压确定充电器输出电流。
在确定总输出功率和充电器输出电压后，根据总输出功率等于充电器输出电压和充电器输出电流的乘积的计算公式，就能计算出充电器输出电流。示例性的，当总输出功率P total为27W，充电器输出电压为9V，由于充电器输出电流等于总输出功率P total除以充电器输出电压，进而得到充电器输出电流为3A。
S2440，根据充电器输出电压和充电器输出电流确定充电参数。
在获得充电器输出电压和充电器输出电流后，就能通过控制充电器输出相对应的电压值和电流值，进而使充电器的输出功率满足终端的充电需求并实现电池的温度控制和终端性能的保证。在实际应用中，还需要比较总输出功率与充电器的最大输出功率，以保证充电器在安全范围内对电池进行充电操作，以免充电器超负荷工作带来安全隐患。在确保充电器输出电压和充电器输出电流均在充电器的性能参数范围内的情况下，确定充电器的充电参数。
S3000，根据充电参数确定充电器的充电输出功率，以使充电器按照充电输出功率对终端充电。
在确定充电参数后，终端向充电器发出充电需求，充电器按照充电器输出电压和充电器输出电流向终端进行充电，进而保证充电器按照充电输出功率对终端外设进行供电和电池充 电。
在实际应用中，通过定期获取充电参数，充电器动态地调整充电输出功率对终端进行充电，以保证终端外设处于稳定供电的前提下，提高电池充电的效率性和安全性。示例性的，在终端通过充电器充电且处于高负载工作状态的情况下，由于电池的当前充电需求功率P bat恒定，充电器的充电参数主要是根据终端的系统功耗值P sys进行调整，以保证终端的性能得到稳定的发挥。而当终端通过充电器充电且处于低负载工作状态的情况下，充电器的充电参数主要是根据电池的技术参数和当前电量进行调整，以保证电池的充电效率。
