本发明涉及移动通信中的充电领域，尤其涉及一种充电控制方法、装置、终端及计算机存储介质。
背景技术
随着通信技术的高速发展，移动终端比如手机、便携式设备(PAD，Portable Device)类产品的屏幕越来越大，功能越来越多，用户经常将多个应用并行操作，导致移动终端的电量消耗越来越多，目前在电池容量技术没有明显突破的基础上，很多用户会插着充电适配器或充电宝在大功率状态下对移动终端进行各种操作，导致移动终端的消耗电流大于充电电流，从而使得充电适配器持续工作在过流状态，如此，容易造成充电适配器被损坏，引发事故。同时，目前的移动终端充电适配器接口趋于统一，大部分接口都是USB接口，所以可以混用不同的充电适配器对移动终端进行充电，但不同的充电适配器充电时输出的电流大小各不相同，混用不同的充电适配器进行充电时，也会出现上述问题。
为解决上述问题，有人提出了一种通过自动识别USB充电适配器的最佳充电电流，从而安全、高效地使用各种类型的USB充电适配器的解决方案；但是，这种解决方案仅适用于各充电适配器混用的情况，部分充电适配器仍然会工作在过流状态，这样的话，处于过流状态的充电适配器仍然会被损坏，引发事故。
因此，如何使充电适配器工作在正常状态是目前亟待解决的问题。

具体实施方式
为了能更好地理解本发明的内容，本文先介绍现有技术中存在的问题。实际应用时，比如：某手机充电适配器的标准配置为额定充电电压/额定充电电流为5V/1A，当把手机设置成屏幕最大亮度，视频最大音量播放，并在后台运行一些应用，同时在射频最大功率发射的情况下时，手机的消耗电流会达1.0A以上，比如：1.1A；这时，当采用该手机的消耗电流大于充电适配器所能提供的额定充电电流；此时如果插上充电适配器继续使用手机，则充电适配器提供的充电电流为1.1A，充电适配器工作在过流状态。再比如：在上述情况下，用户也可能使用标准配置为额定充电电压/额定充电电流为5V/500mA的充电适配器给该手机充电，则该充电适配器也会持续工作在超过500mA的过流状态。其中，一些应用可以包括：微信、QQ、蓝牙、游戏等，所述微信及QQ是一种聊天工具。
如果充电适配器长时间工作在过流状态下，则充电适配器输出的电压 会逐步下降，当充电适配器对充电电压无限制时，则会导致充电适配器的电压降到很低，使得实际工作功率小于充电适配器的额定功率。这样，一方面会导致充电适配器不能高效地为移动终端充电，即通过移动终端的电源管理集成电路(PMIC，Power Management Integrated Circuit)转换到实际电路中的转换效率低，进而导致电池反向提供到移动终端的电流过大，加速了电池能量的消耗；另一方面会导致充电适配器发热发烫，易老化；因此，充电适配器的使用寿命和稳定性受到很大影响。
现有技术是通过自动识别USB充电适配器的最佳充电电流的方法来解决解决充电配器过流的问题，从而能安全、高效地使用各种类型的USB充电适配器。但是，这种方法仅适用于各充电适配器混用的情况。
目前，虽然大部分充电适配器对输出电流设有上限，但是很多移动终端的PMIC是不具备对输入的充电电流进行设限的功能的，所以现有技术中提供的方案还是会导致部分充电适配器工作在过流状态；另外，由于不同的移动终端具有不同的充电策略，而充电策略的设计较为复杂，如果混用不同类型的充电适配器对移动终端进行充电，将可能会导致与移动终端自身的充电策略产生冲突，因此，这种方法也不能模块化应用到各类移动终端中，应用范围非常有限。
基于此，在本发明的各种实施例中：采集充电电压，确定采集的充电电压不大于预设的电压值时，控制所述充电电压不低于预设的充电电压阈值。
下面通过附图及具体实施例对本发明的技术方案做进一步的详细说明。
实施例一
本实施例提供的一种充电控制方法，如图1所示，该方法主要包括以下步骤：
步骤101，采集充电电压；
本步骤中，对终端进行充电时，需实时采集充电适配器输出的充电电压。
步骤102，确定采集的充电电压不大于预设的电压值时，控制所述充电电压不低于预设的充电电压阈值；
本步骤中，所述预设的电压值与预设的充电电压阈值可以相同，也可以不同。
该方法还可以包括：确定采集的充电电压大于预设的电压值时，控制所述充电电压不低于预设的充电电压阈值。
在确定充电电压不大于预设的电压值之前，首先要预设充电电压阈值的充电标识，以标识终端消耗的电流是否超过充电适配器的额定电流；这里，将所述充电电压阈值的充电标识的初始状态设置为无效状态。
在充电过程中，采集充电适配器输出的充电电压，确定充电电压不大于预设的电压值时，将所述充电电压阈值的充电标识的状态设置为有效状态，并根据设置的所述充电电压阈值充电标识的有效状态，向用户发送用于建议关闭后台运行应用的提示；具体地，可以通过终端的用户界面(UI，User Interface)向用户发送信息提示框，以提示用户此时终端消耗的电流已经超过充电适配器工作的额定电流，并建议用户关闭后台运行的相关应用。这里，所述信息提示框还可以向用户提供是否继续提醒的选择提示，当用户选择了不再提醒时，即收到用户不再提醒的指示后，在后续的充电过程中，所述充电电压阈值的充电标识的状态从有效状态变成无效状态时，或从有效状态变成无效状态时，所述信息提示框就不会再出现，以避免干扰用户。
其中，所述充电电压阈值的充电标识的状态为无效状态包括：所述充电电压阈值的充电标识的状态值为0；相应地，所述充电电压阈值的充电标 识的状态为有效状态包括：所述充电电压阈值的充电标识的状态值为1。
这里，由于充电适配器的工作原理决定了充电适配器的功率是一定的，所以当充电适配器输出的充电电压低于额定电压时，终端消耗的电流就会超出充电适配器的额定电流；因此，当充电标识为有效状态时，即可确定终端消耗的电流已经超过充电适配器工作的额定电流。
另外，在充电过程中，还需实时监控充电电压，当确定充电电压大于预设的电压值时，取消预设的充电电压阈值。
具体地，当终端离开大功率的使用场景时，充电适配器不再工作在过流状态，输出的充电电压将逐步上升，当充电电压大于预设的电压值时，取消预设的充电电压阈值，按照原有的充电策略进行充电，并将所述充电电压阈值的充电标识重新设置为无效状态，直至充电过程结束。
实际应用时，可以预设一个电压监控范围4.7V-4.75V，这里，可将电压值预设为4.75V，当确定采集的充电电压不大于4.75V时，相应地，将所述电压范围中的最小电压值4.7V设置为充电电压阈值，这时，所述预设的电压值与所述预设的电压阈值不相同。或者，也可将电压值预设为4.7V，当确定采集的充电电压不大于4.7时，相应地，将所述电压范围中的最小电压值4.7V设置为充电电压阈值，这时，所述预设的电压值与所述充电电压阈值相同。
在充电过程中，当充电电压大于4.75V时，将取消4.7V的充电电压阈值设置，按照原有的充电策略进行充电，并将所述充电电压阈值的充电标识重新设置为无效状态，直至充电过程结束。
当确定充电电压不大于预设的电压值时，控制充电电压不低于设置的所述充电电压阈值，控制终端所需供电的一部分从充电适配器中获取，另一部分从终端的电池中获取，从而将充电适配器保持恒压状态，即充电适配器的功率保持在恒定状态，以保证终端的PMIC能把电量高效转换到实 际电路中，即保证高效地为终端充电。
实际应用时，比如终端需要1.5A的电流，则控制充电适配器向终端提供1A的电流，控制终端的电池向终端提供0.5A的电流。
实际应用中，如果将电压范围设置为4.7V-4.75V时，在充电过程中，则应将所述充电电压控制在不低于4.7V的状态。
本实施例提供的充电控制方法，在充电适配器电流过载的情况下，能够保证充电适配器的充电电压和功率不会过度下降，损坏充电适配器。
另外，本实施例提供的充电控制方法，不需要复杂的算法和逻辑，保证PMIC的高效转换。
而且，并在充电过程充分安全的情况下，可以通过信息提示框的选择不再提示用户终端消耗的电流已经超过充电适配器工作的额定电流的信息，提升用户体验。
实施例二
相应于实施例一，本实施例还提供了一种充电控制装置，如图2所示，所述装置包括：采集模块21、确定模块22；其中，
所述采集模块21，配置为采集充电电压；
所述确定模块22，配置为确定所述采集模块21采集的充电电压不低于预设的电压值时，控制所述充电电压不低于预设的充电电压阈值。
其中，所述预设的电压值与预设的充电电压阈值可以相同，也可以不同。
所述确定模块22，还配置为确定采集的充电电压不大于预设的电压值时，控制所述充电电压不低于预设的充电电压阈值。
所述确定模块22在确定充电电压不大于预设的电压值之前，首先要预设充电电压阈值的充电标识，以标识终端消耗的电流是否超过充电适配器的额定电流；这里，所述确定模块22将所述充电电压阈值的充电标识的初 始状态设置为无效状态。
在充电过程中，所述确定模块22，配置为：确定采集模块21采集的充电电压不大于预设的电压值时，将所述充电电压阈值的充电标识的状态设置为有效状态；
相应地，所述装置还包括：信息提示模块23；其中，
当所述确定模块22将设置的所述充电电压阈值充电标识的有效状态发送至信息提示模块23时，所述信息提示模块23，配置为根据设置的所述充电电压阈值充电标识的有效状态，向用户发送用于建议关闭后台运行应用的提示。具体地，可以通过终端的UI向用户发送信息提示框，，以提示用户此时终端消耗的电流已经超过充电适配器工作的额定电流，并建议用户关闭后台运行的相关应用。这里，所述信息提示模块23还配置为向用户提供是否还要提醒的选择提示，且当收到用户不再提醒的指示后，在后续的充电过程中，所述充电电压阈值的充电标识的状态从有效状态变成无效状态时，或从有效状态变成无效状态时，不再对用户提供信息提示，以避免干扰用户。
其中，所述信息提示模块23位于终端的应用层中；所述充电电压阈值的充电标识的状态为无效状态包括：所述充电电压阈值的充电标识的状态值为0；相应地，所述充电电压阈值的充电标识的状态为有效状态包括：所述充电电压阈值的充电标识的状态值为1。
这里，由于充电适配器的工作原理决定了充电适配器的功率是一定的，所以当充电适配器输出的充电电压低于额定电压时，终端消耗的电流就会超出充电适配器的额定电流；因此，当充电标识为有效状态时，即可确定终端消耗的电流已经超过充电适配器工作的额定电流。
另外，在充电过程中，所述确定模块22还需实时监控充电电压，当所述确定模块22确定充电电压大于预设的电压值时，取消预设的充电电压阈 值；
具体地，当终端离开大功率的使用场景时，充电适配器不再工作在过流状态，输出的充电电压将逐步上升，当充电电压大于预设的电压值时，所述确定模块22取消预设的充电电压阈值，按照原有的充电策略进行充电，并将所述充电电压阈值的充电标识重新设置为无效状态，直至充电过程结束。
实际应用时，所述确定模块22可预设一个电压范围4.7V-4.75V，这里，所述确定模块22可将电压值预设为4.75V，当确定采集的充电电压不大于4.75V时，相应地，将所述电压范围中的最小电压值4.7V设置为充电电压阈值，这时，所述预设的电压值与所述预设的电压阈值不相同。或者，也可将电压值设置为4.7V，当确定采集的充电电压不大于4.7V时，相应地，将所述电压范围中的最小电压值4.7V设置为充电电压阈值，这时，所述预设的电压值与所述充电电压阈值相同。
在充电过程中，当充电电压大于4.75V时，所述确定模块22将取消设置的4.7V的充电电压阈值，按照原有的充电策略进行充电，并将所述充电电压阈值的充电标识重新设置为无效状态，直至充电过程结束。
当所述确定模块22确定充电电压不大于预设的电压值时，所述确定模块22，具体配置为：控制终端所需供电的一部分从充电适配器中获取，另一部分从终端的电池中获取，从而将充电适配器保持恒压状态，即充电适配器的功率保持在恒定状态，以保证终端的PMIC能把电量高效转换到实际电路中，即保证高效地为终端充电。
实际应用时，比如终端需要1.5A的电流，则控制模块23控制充电适配器向终端提供1A的电流，控制终端的电池向终端提供0.5A的电流。
实际应用时，本发明实施例提供的采集模块21、确定模块22、控制模块23可由充电控制装置中的中央处理器(CPU，Central Processing Unit)、 数字信号处理器(DSP，Digital Signal Processor)或可编程逻辑阵列(FPGA，Field－Programmable Gate Array)结合具体的电路实现；信息提示模块23可由充电控制装置中的CPU、DSP或FPGA结合显示装置实现。
与现有技术相比较，本实施例提供的装置不需要终端的硬件平台具有特殊的功能，当终端混用不同类型的充电适配器进行充电时，该装置提供的充电策略不会和终端自身的充电策略冲突，并且所述装置可以模块化或以APP的形式应用到各类终端中。
实施例三
本实施例以10寸Android PAD类终端产品为例对本发明各实施例提供的方法做更具体地说明；其中所述10寸Android PAD类终端产品是以市场上通常应用的主芯片及附带的电源管理集成电路PMIC的硬件平台为基础的。
当给终端进行充电时，硬件连接示意图如图3所示，所述终端包括电源管理集成电路PMIC 31、电池32、电路33；其中，
所述电源管理集成电路PMIC 31，配置为接收充电适配器34输入的电压，并将充电适配器34提供的A点电能转换后给终端供电，包括：通过B点给终端的电路33供电以及通过C点给电池32充电等；其中，所述B点为电路33供电的电压输入端口，所述C点为电池充电的电压输入端口；
所述电路33，包括：WIFI电路、全球定位系统(GPS，Global Position System)电路等。
具体地，如图4所示，本实施例充电控制方法主要包括几个步骤：
步骤401，采集充电电压；
本步骤中，在终端的内核驱动层由电源管理集成电路PMIC31采集充电适配器输出的充电电压Vin，即图3中的A点电压。
步骤402，确定采集的充电电压不大于预设的电压值时，控制所述充电 电压不低于预设的充电电压阈值；
本步骤中，所述预设的电压值与预设的充电电压阈值可以相同，也可以不同。
电源管理集成电路PMIC31在确定充电电压不大于预设的电压值之前，首先要在终端的应用层中定义充电电压阈值的充电标识Vcharg_flag、定义UI的信息提示功能；这里，所述充电标识Vcharg_flag用于标识终端消耗的电流是否超过充电适配器的额定电流；所述将所述充电电压阈值的充电标识Vcharg_flag的初始状态设置为无效状态。
其中，电源管理集成电路PMIC31可预设一个电压监控范围为4.7V-4.75V，这里，可将电压值预设为4.75V，当确定采集的充电电压不大于4.75V时，将所述电压范围中的最小电压值4.7V设置为充电电压阈值；这时，所述预设的电压值与所述预设的电压阈值不相同。或者，也可将电压值设置为4.7V，当确定采集的充电电压不大于4.7时，相应地，将所述电压范围中的最小电压值4.7V设置为充电电压阈值，这时，所述预设的电压值与所述充电电压阈值相同。在充电过程中，当充电电压大于4.75V时，将取消4.7V的充电电压阈值设置，按照原有的充电策略进行充电，并将所述充电电压阈值的充电标识清零，直至充电过程结束。
这里，所述将电压范围设置为4.7V-4.75V是根据实验得出的，此电压范围对于市场上绝大部分额定电压为5V的充电适配器都适用，比如：标准配置为额定充电电压/额定充电电流分别为5V/1A、5V/500mA、5V/1.5A、5V/2A的充电适配器；另外，对于其它额定电压的充电适配器，一般也可以按照比充电适配器额定电压值小于0.3V的标准对充电电压阈值进行设置，然后再进行一些实验微调即可确定出电压范围。
在充电过程中，电源管理集成电路PMIC31采集充电适配器输出的充电电压Vin，当确定充电电压不大于预设的电压值时，将所述充电电压阈值 的充电标识的状态设置为有效状态，并通过终端的UI向用户发送信息提示框，以提示用户此时终端消耗的电流已经超过充电适配器工作的额定电流，并建议用户关闭后台运行的相关应用。这里，所述信息提示框还向用户提供是否还要提醒的选择提示，当用户选择了不再提醒时，即收到用户不在提醒的指示后，在后续的充电过程中，所述充电电压阈值的充电标识的状态从有效状态变成无效状态时，或从有效状态变成无效状态时，所述信息提示框就不会再出现，以避免干扰用户。
其中，所述充电电压阈值的充电标识的状态为无效状态包括：所述充电电压阈值的充电标识的状态值为0；相应地，所述充电电压阈值的充电标识的状态为有效状态包括：所述充电电压阈值的充电标识的状态值为1。
另外，在充电过程中，还需实时监控充电电压，当电源管理集成电路PMIC31确定充电电压大于预设的电压值时，取消预设的充电电压阈值。
具体地，当终端离开大功率的使用场景时，充电适配器不再工作在过流状态，输出的充电电压将逐步上升，当充电电压大于预设的电压值时，取消设置的充电电压阈值，按照原有的充电策略进行充电，并将所述充电电压阈值的充电标识重新设置为无效状态，直至充电过程结束。
这里，当电源管理集成电路PMIC31确定充电电压不大于预设的电压值时，控制充电电压不低于所述充电电压阈值，具体地，控制终端所需供电的一部分从充电适配器中获取，另一部分从终端的电池中获取，从而将充电适配器保持恒压状态，即充电适配器的功率保持在恒定状态，以保证终端的电源管理集成电路PMIC31能把电量高效转换到实际电路中，即保证高效地为终端充电。
这里，为了验证本发明实施例提供的充电控制方法及装置的实用性，本实施例在同样的外部条件下，分别采用本发明实施例的充电控制方案、现有技术中的充电控制方案对终端进行充电，以更好地验证本发明实施例 的有益效果。
具体地，同样的外部条件包括：在对终端进行充电之前，将终端的工作状态设置为：屏幕最大亮度、WIFI功能开启、蓝牙(BT，BlueTooth)等硬件功能开启、射频大功率发射、视频处于播放状态，测试此时的终端消耗电流为1.78A，再用标准配置为额定充电电压/额定充电电流5V/1.5A充电适配器对终端进行充电；
当终端连接有充电适配器时，电源管理集成电路PMIC31将图3中A点的电压转换成B点电压和C点电压之和、将A点的电流转换为B点电流和C点电流之和，即所述充电适配器向所述终端中的电路33提供所需的电能以及向电池32提供所需的电能。
这里，当采用本发明实施例的充电控制方案对终端进行充电时，对图3中的A点、B点以及C点的电流进行测试，测得B点的电流是1.78A，而此时A点的电流则从1.5A的额定电流逐步被拉到了1.59A，充电电压Vin从5V的额定电压逐步下降到充电阈值电压4.7V。该充电适配器提供的电流/电压经电源管理集成电路PMIC31的转换后，通过B点为电路33提供的电流/电压为1.74A/3.8V，同时C点电池反向通过B点向电路33供电，为电路33提供40mA电流，充电适配器的电压保持在4.7V-4.75V之内，同时，在充电适配器在过流状态时，其功率不会过度下降；因此，充电适配器达到平衡状态。
当充电电压Vin从5V的额定电压逐步下降到充电阈值电压4.7V时，通过终端的UI向用户发送信息提示框，提示用户此时终端消耗的电流已经超过充电适配器工作的额定电流，并建议用户终端关闭后台运行的相关应用。这里，所述信息提示框还向用户提供是否还要提醒的选择提示，当用户选择了不再提醒时，即收到用户不再提醒的指示后，在后续的充电过程中，所述充电电压阈值的充电标识的状态从有效状态变成无效状态时，或 从有效状态变成无效状态时，所述信息提示框就不会再出现，以避免干扰用户。
而采用现有技术中的充电控制方法及装置对终端进行充电时，测得A点的充电电流从1.5A的额定电流逐步被拉到1.62A，充电电压Vin从5V逐步下降到4.2V，功率下降到6.8瓦；因此，该充电适配器提供的电能经电源管理集成电路PMIC31转换后，通过B点向电路33提供的电流/电压仅为1.64A/3.8V，同时迫使C点电池反向通过B点向电路33供电，为电路33提供140mA的电流，且随着长时间使用，充电适配器电压和功率还在逐步下降，这样，充电适配器严重发热，将很可能会对充电适配器造成损坏；同时，使用该方法也无法在终端界面上提示用户充电适配器处于过流状态。
基于上述充电控制装置，本发明实施例还提供了一种终端，包括图2所示的充电控制装置的基本结构及其各种变形和等同替换，不做赘述。
综上所述，采用本发明提供的各实施例可以在大功率的场景下对终端进行各种操作；以及在混用非标配充电适配器的情况下，避免充电适配器长时间工作在过载状态而造成损坏，确保电源管理集成电路PMIC高效率进行电能转换以给终端供电。
在对终端进行充电时，不但能保证用户安全，还能保证电能高效的转换，并且在充电适配器电流过载的情况下及时发送信息提示框，提升了用户体验。
