Description

充电电流门限调整方法、终端设备和图形用户界面
本申请要求于2017年1月3日提交中国专利局、申请号为201710002482.8、发明名称为“一种充电的方法和设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及智能温控领域，尤其涉及一种充电电流门限调整方法、终端设备和图形用户界面。
背景技术
智能温控技术是一种利用温度作为输入并反馈信号的技术，被广泛应用于智能终端及其它有温度要求的产品中。随着智能终端的耗电量和发热量逐渐增加，温控策略愈发重要，因此基于场景细分和多点的温控策略也应运而生。例如当前部分终端产品的表面温控策略，根据不同位置的多个温度传感器上报的温度，在识别出使用场景基础上设定对应温度门限，当上报的温度超过对应各级门限时，终端判断主要热源位置并执行相应的温控策略。
温控策略一方面包括控制主动冷却模块执行主动冷却动作(例如通信设备风扇调速、热电制冷开关动作等等)，进行主动降温；另一方面包括发热源发热量控制(例如限制CPU主频、调整充电电流等)，延缓或阻止温度继续上升。智能场景温控策略的核心是准确进行场景识别，并根据识别出的场景特点及用户心理预期做相应的功耗控制方案。在此基础上，结合产品热开发经验为不同温度采样点设定不同级别的门限及相应动作，例如处理单元的频率控制、充电电流限制、调整显示模块亮度和刷新频率控制等等。
终端在运行高耗电应用时，电池电量迅速下降，同时发热积累导致温度急剧上升。当通过充电维持设备持续运转时，现有温控策略对充电电流的限制可能导致充电能量小于消耗能量，需要通过电池放电来维持运转，使得电池电量逐步降低，甚至最终导致关机。

外部电源检测装置8003作为一种充电电路，可以包括例如充电芯片等，用于连接电源适配器等外部电源，还用于检测设备的充电状态。例如可以识别出外部充电器的类型，检测外部电源是否为电池充电等等。外部电源检测装置8003还可以包括电池等电源，用于向终端设备800的负载提供正常工作的电压。

在具体实现中，作为一种实施例，处理器8001可以包括一个或多个CPU。
在具体实现中，作为一种实施例，终端设备800可以包括多个处理器。这些处理器中的每一个可以是一个单核(single-CPU)处理器，也可以是一个多核(multi-CPU)处理器。这里的处理器可以指一个或多个设备、电路、和/或用于处理数据(例如计算机程序指令)的处理核。

本申请实施例提供了一种充电电流门限调整方法，参照图2中所示，包括步骤S101-S102：
S101、在有外部电源为电池充电，并且电池的电量未增加时，检测电池是否满足第一预设条件的至少一项。
具体的，由外部电源检测装置检测是否有外部电源为电池充电，并且由电量计检测电池的电量，并且二者将检测结果反馈给处理器。需要说明的是，二者可以连续检测或者间隔一定周期检测，本申请实施例在此并不限定。
第一预设条件包括：电池的剩余电量小于第一电量阈值，例如，当第一电量阈值为10％时，电池的剩余电量小于10％即为满足预设条件；电池的电量减小率大于第一电量减小率阈值；电池的放电电流大于第一放电电流阈值，例如，当第一放电电流阈值为0mA时，即只要有电池的放电电流即为满足预设条件；根据电池的电量减小率和剩余电量计算的电池可供电时间小于第一时间阈值，例如。本领域技术人员可以理解，上述预设条件可以任意组合。
S102、在电池满足第一预设条件的至少一项时，提高电池的充电电流门限，同时根据提高的充电电流门限相应降低发热器件的功耗或者控制冷却单元执行冷却动作。
当有外部电源供电，而电池的电量并未增加时，如果再进一步判断满足上述预设条件，说明此时外部电源供电不足。通过提高电池的充电电流门限，加大电池的充电电流，可以防止电池电量持续下降，使得外部电源供电足以满足终端设备的耗电。
降低发热器件的功耗的方式可以包括：降低显示模块的显示亮度，例如将显示模块的亮度从150nit降低至125nit；或者，降低中央处理器的最高频率阈值，例如将中央处理器的最高频率阈值从1.5GHz降低至1.3GHz；通过处理器控制关闭造成大功耗的应用(软件)，例如视频播放、电话、录像、游戏等，并显示提示信息，示例性的参照图3中所示，在显示界面上显示图标或者文字提示“充电中，启动温度保护，请稍后使用”等等。以上仅示例性的提供了几种被动降温方法，用于补偿由充电电流门限向上调整带来的温升。本领域技术人员还可以想到，对于温控策略中除了充电电流门限以外的其他变量进行加严，以达到被动降温效果，同样适用于本申请的保护范围。
控制冷却单元执行冷却动作的方式可以包括：启动冷却单元进行冷却或加强冷却单元的冷却功率。例如可以提高降温风扇的转速，打开热电制冷开关等，应用于存在主动冷却单元的场景。
本申请实施例提供的充电电流门限调整方法，通过在有外部电源为电池充电，并且电池的电量并未增加的条件下，判断电池的电量和/或放电电流满足至少任一项预设条件时，提高电池的充电电流门限，同时降低发热器件的功耗或者控制冷却单元执行冷却动作。通过对温控策略中的充电电流门限进 行调整，解决了因为温控策略对充电电流的限制所导致的电池电量持续下降。
下面对步骤S101中所述的根据电池的电量减小率和剩余电量计算的电池可供电时间进行详细描述，参照图4中所示，在步骤S101之前可以包括步骤S103-S104：
S103、根据一段时间电池的电量减小的差值得到电池的电量减小率。
具体的，间隔一定时间分别采集电池的电量，电量减小差值除以间隔时间即得到电量减小率。
S104、根据电池的剩余电量以及电池的电量减小率计算电池的可供电时间。
具体的，将电池的剩余电量除以电量减小率可以计算得到电池的可供电时间。
需要说明的是，还可以根据设备、电池的具体特点，对计算的电池的可供电时间做修正，例如将5％电量放空与将30％电量放电至25％，虽然电池的电量变化情况相同，但其所经过的时间很可能不一样，可以根据经验适当修正。
可选的，本申请针对步骤S102中所述的提高电池的充电电流门限提供一种实现方式，具体的可以通过每个周期按照步骤电流值提高充电电流门限，参照图5中所示，步骤S102包括步骤S1021-S1022：
S1021、根据电池的电量和放电电流预测目标充电电流，如果目标充电电流大于充电电流门限并且目标充电电流取值合法，则将充电电流门限设置为目标充电电流。
为了防止过冲以及加快收敛速度等，可以通过执行自动控制理论中的比例、微分、积分控制或者三者任意组合，以电池的电量和放电电流作为控制过程的输入参数，将目标充电电流作为控制过程的输出结果，从而根据电池的电量和放电电流预测目标充电电流。
S1022、每个周期按照固定的或可变的步进电流值提高充电电流门限，直到电池满足第二预设条件中的至少一项。
第二预设条件包括：电池的剩余电量大于等于第二电量阈值；电池的电量减小率小于等于第二电量减小率阈值；电池的放电电流小于等于第二放电电流阈值；根据电池的电量减小率和剩余电量计算的电池可供电时间大于等于第二时间阈值。
需要说明的是，步骤S1022并不一定依赖于步骤S1021中的目标充电电流，即可以在目标充电电流的基础上进一步按照步进电流值调整，或者不执行步骤S1021而直接按照步进电流值调整。例如假设当前充电电流门限为1A，步进电流值为0.05A，则将充电电流门限调整为1.05A，下一个周期进行同样的调整。另外，本申请并不限定步进电流值为固定值，其同样可以是可变值，可以前一周期的值大于后一周期的值，例如前一周期步进电流值为0.1A，下一周期步进电流值变为0.08A，再下一周期步进电流值变为0.05A等等。
上述步骤S1021和S1022相当于自动控制理论中的闭环控制，可选的， 本申请针对步骤S102中所述的提高电池的充电电流门限提供另一种实现方式，即可以采用开环控制，具体的可以通过直接将充电电流门限设置为固定门限来实现，参照图6中所示，步骤S102可以包括步骤S1023：
S1023、直接将充电电流门限设置为充电电流阈值。
另外，可以根据电量的亏损情况将充电电流阈值设置为不同的值，即可以有多级充电电流门限。例如，当电池的电量越低时，将充电电流门限设置得越高，使得电量亏损较多时快速进行充电，电量亏损较少时涓流充电。
可选的，在改变电池充电状态时，本申请实施例还可以在终端设备的图像用户界面上显示提示信息，参照图7中所示，上述方法还包括步骤S105和S106：
S105、在电池满足第一预设条件的至少一项时，在终端设备的显示界面上显示提示信息，以提示用户当前已提高电池的充电电流门限，并已降低发热器件的功耗或者控制冷却单元执行冷却动作。
示例性的，参照图8中所示，可以显示“调整进入充电并降功耗模式”、“进入提高充电电流并降低功耗模式”等，具体的提示信息包括但不限于文字、图标、图形、图案等形式。本领域技术人员可以理解，图中仅示例性的描述提示信息的表现方式，并不意在限定提示信息的具体内容。
S106、当电池满足步骤S1022所述的第二预设条件的至少一项时，恢复至原温控策略，停止在移动终端的显示界面上显示上述提示信息。
例如，将充电电流门限恢复为调整前的值，将温控策略中其他加严的变量恢复为加严之前的值等。
下面举例对上述实施方式进行详细说明。
例如，假设某终端设备的第一电量阈值设为10％，第一放电电流阈值设为0mA。每个周期对外部电源和电池电量进行监控，在外部电源检测装置检测到有外部电源提供外部供电的情况下，并且当电量计检测到电池电量降低至低于10％时，电量计开始对电池的放电电流进行监控。当电量计检测到放电电流大于0mA时，由处理器判断满足第一预设条件，控制显示界面上显示提示信息，并且处理器的低电量修正模块控制外部电源检测装置在该周期以预设的步进电流值提高温控策略的充电电流门限。例如当前温控策略的充电电流门限为1A，步进电流值为50mA，则提高充电电流门限至1.05A。下一个周期执行同样的操作，直至电池满足第二预设条件中的至少一项，并且自动恢复原有温控策略。
此时，由于充电电流增大引发的损耗变大进而引起发热，由处理器的温控模块对除了充电电流门限以外的其他控制变量进行加严来消除，例如降低处理器的最高频率阈值，降低显示模块的显示亮度等。例如，当将原为1A的充电电流门限限调整到1.1A时，增加的0.1A充电电流使设备表面温度增加0.5度，则可以将中央处理器的最高频率阈值从1.5GHz降至1.3GHz，或者将显示模块的显示亮度从150nit(尼特)降至125nit等，以补偿由充电电流门限上调带来的额外温升。
本申请实施例提供的充电电流门限调整方法和装置，主要是通过监控电池电量、电量变化情况以及电池放电电流情况，来提高电池的充电电流门限，以减少因温度控制导致充电入不敷出，或者设备功耗过大导致触发温度安全保护，或者耗电量过大超出外部电源能提供的最大能量等。同时考虑到提高了温控策略的充电电流门限，有可能引起电池发热量增加，因此相应加严了温控策略的其余控制变量来保证整体发热量不增加，既消除因温控策略导致的电池电量持续减少，又可以一定程度保障热体验。
本申请实施例所述的充电电流门限包括但不限于普通温控策略中的充电电流门限，对于快速充电等充电策略中的充电电流门限同样适用，只要电池的电量、放电电流和电压中的至少一个满足预设条件，就可以按照本申请实施例提供的方法调整充电电流门限。另外，本申请实施例所述的充电电流门限调整方法可以应用于有外部电池供电时，也可以应用于没有外部电池供电时，本申请实施例不作限定。
