- each charging module When the charger is connected to the charging interface, the charging control function is activated. Assuming that the set charging current of each charging module is 1000 mA, three charging modules are used in the entire terminal device. At this time, each charging module starts to charge the electric energy conversion output input on the charger to the battery with a setting charging current of 1000 mA, and each temperature sensor starts to monitor the temperature data around the corresponding charging module in real time, and sends it to the charging control device. .

Description
本申请涉及但不限于通讯技术领域，尤其涉及一种终端设备的充电控制方法、装置及终端设备。
终端产品的主板上器件布局一般比较密集，这使得充电模块一般都会跟其他某个或某几个功能模块靠的比较近，比如中央处理器CPU、射频功放、无线保真wifi模块、发光二极管LCD背光驱动、摄像头模组等。终端产品在使用中一般都会遇到充电时做其他操作，比如通过移动网络上网，玩游戏等。这些操作会导致终端产品发热比较严重的情况，特别是局部发热严重。这主要是该终端产品的充电模块和其他模块同时工作，同时产生大量热量，而两个模块之间的空间距离又比较近，造成了热量的叠加，使得局部发热明显。
相关的终端产品或者方案，充电模块一般只有一个，使用中如果遇到局部温升较为严重的情况，一般通过降低充电电流来降低温度，从而减少充电发热带来的影响。但这样轻则影响用户的使用体验，重则造成用户误认为终端出现异常故障。

可以理解，在其他实施例中，所述预设阈值还可以包括多个温度上限和多个温度下限，判断模块203根据该温度数据与该多个温度上限和多个温度下限判断对应温度传感器102预设范围内的发热状况。此时所述发热状况可以再细分为多个阶段。控制模块204根据该多个阶段的发热状况控制每个充电模块101的充电电流。
例如，所述预设阈值还可以包括温度上限T3、T4和温度下限T5、T6，其中T3＞T4＞T5＞T6。当该温度数据大于该温度上限T3时，判断模块203判断对应温度传感器102临近的工作模块当前发热非常高，控制模块204直接控制对应的充电模块101停止工作。
当该温度数据介于该温度上限T3与T4之间时，判断模块203判断对应温度传感器102预设范围内的工作模块当前发热比较高，控制模块204控制对应的充电模块101的充电电流降低50％。
当该温度数据介于该温度上限T4与温度下限T5之间时，判断模块203判断对应温度传感器102临近的工作模块当前发热正常，控制模块204控制对应的充电模块101维持原充电电流。
当该温度数据介于该温度下限T5与T6之间时，判断模块203判断对应温度传感器102临近的工作模块当前发热比较低，控制模块204控制对应的充电模块101的充电电流升高50％。
当该温度数据小于该温度下限T6时，判断模块203判断对应温度传感器102临近的工作模块当前发热非常低，控制模块204控制对应的充电模块101

可选地，该控制模块204还设置为当部分充电模块101(如目标充电模块)降低或升高充电电流后，控制其他充电模块101对该降低或升高的充电电流进行补偿，使得该终端设备总体充电电流维持原额定的状态。
例如，当有一个目标充电模块因周围的温度较高而将充电电流降低50mA时，控制模块204控制另一个周围温度较低的充电模块101将充电电流升高50mA；或者控制另一个周围温度较低且当前未工作的充电模块101开始工作，充电电流为50mA；或者控制一组周围温度较低的充电模块101升高充电电流，该组充电模块101升高的充电电流总和为50mA。
在本实施例中，该控制模块204可以控制另外一个或一组充电模块101对目标充电模块降低或升高的充电电流进行补偿。当控制一组充电模块101对该降低或升高的充电电流进行补偿时，可以平均分配补偿的充电电流，也可以根据该组中每个充电模块101与目标充电模块的距离或每个充电模块102周围的温度数据等条件按照预定比例分配补偿的充电电流。
例如，当有一个充电模块A因周围的温度较高而将充电电流降低60mA时，控制模块204控制一组周围温度较低的充电模块101升高充电电流。假设该组充电模块101包括两个充电模块B和C，其中，充电模块B与该充电模块A的距离较近，而充电模块C与该充电模块A的距离较远。控制模块204控制充电模块B将充电电流升高20mA，控制充电模块C将充电电流升高40mA。或者，假定充电模块B周围的温度高于充电模块C周围的温度，控制模块204控制控制充电模块B将充电电流升高20mA，控制充电模块C将充电电流升高40mA。
可以理解，在其他实施例中，控制模块204还可以根据设定和当前状况采取其他的方式来使该终端设备总体充电电流维持原额定的状态。

补偿，保持该终端设备的总体充电电流维持原额定的状态，从而避免影响该终端设备的充电速度。
如图3所示，本发明第三实施例提出一种充电控制方法，应用于终端设备中，用于对终端设备的充电过程进行动态控制。在本实施例中，所述终端设备可以是移动电话、智能电话、笔记本电脑、数字广播接收器、PDA、PAD等移动终端。
所述终端设备包括充电控制装置，多个充电模块，多个温度传感器，电池，及充电接口。在本实施例中，该方法还可以应用于该充电控制装置上。
该充电接口连接充电器，通过充电模块对该终端设备的电池进行充电。
该终端设备上的每个充电模块均能将充电器上输入的电能转换输出充入到电池上，并能够接收充电控制装置的控制，实时改变充电电流。值得注意的是，该多个充电模块分散布局在该终端设备上的不同位置，以分散充电时发热的区域，避免热量叠加。每个温度传感器分别对应布局在每个充电模块附近，用于实时监测环境温度的变化，并将对应的充电模块周围的温度数据反馈给该充电控制装置。

该充电控制装置可以实时接收该温度数据，也可以每隔预定时间接收一次该温度数据。
S302，将接收到的温度数据与预设阈值进行对比，判断对应温度传感器周围的发热状况。
所述预设阈值包括预设的温度上限阈值和预设的温度下限阈值，例如温度上限T1和温度下限T2。所述发热状况包括发热较高、发热较低和发热正常。
当该温度数据大于或等于预设的温度上限阈值，如该温度上限T1时，该充电控制装置判断对应温度传感器预设范围内的工作模块当前发热较高，造成此区域温度升高。
当该温度数据小于或等于预设的温度下限阈值，如该温度下限T2时，该充电控制装置判断对应温度传感器预设范围内的工作模块当前发热较低。此时可能改温度传感器临近的发热较高的工作模块已经停止工作，此位置附近环境温度正在逐步降低。
当该温度数据介于该温度上限T1及温度下限T2(或者可以是小于或等于温度上限T1且大于或等于温度下限T2)之间时，该充电控制装置判断对应温度传感器临近的工作模块当前发热正常。
S303，根据判断出的发热状况控制每个充电模块的充电电流。
所述控制充电电流包括升高充电电流、降低充电电流和维持原充电电流。
参阅图4所示，为图3中步骤S303的第一种流程图。
所述根据判断出的发热状况控制每个充电模块的充电电流包括步骤S401-S403：
S401，当该温度传感器预设范围内的工作模块当前发热较高时，控制对应的充电模块降低充电电流，直到该充电模块停止工作。
在本实施例中，可以根据该温度数据的高低控制该充电模块降低充电电流的程度。例如，当该温度数据大于该温度上限T1的差值为1□C时，控制对应充电模块的充电电流降低25mA。另外，也可以根据预定比例控制该充电模块降低充电电流的程度。例如，当该温度数据大于该温度上限T1时，控制对应充电模块的充电电流降低50％。
S402，当该温度传感器临近的工作模块当前发热较高时，控制对应的充
电模块开始工作或者升高充电电流。
在本实施例中，可以根据该温度数据的高低控制该充电模块升高充电电流的程度。例如，当该温度数据小于该温度下限T2的差值为1□C时，控制对应充电模块的充电电流升高25mA。另外，也可以根据预定比例控制该充电模块升高充电电流的程度。例如，当该温度数据小于该温度下限T2时，控制对应充电模块的充电电流升高50％。
S403，当该温度传感器临近的工作模块当前发热正常时，控制对应的充电模块维持原充电电流，即继续按原来的充电电流对电池进行充电。
可以理解，在其他实施例中，所述预设阈值还可以包括多个温度上限和多个温度下限，该充电控制装置根据该温度数据与该多个温度上限和多个温度下限判断对应温度传感器周围的发热状况。此时所述发热状况可以再细分为多个阶段。然后根据该多个阶段的发热状况控制每个充电模块的充电电流。
例如，所述预设阈值还可以包括温度上限T3、T4和温度下限T5、T6，其中T3＞T4＞T5＞T6。当该温度数据大于该温度上限T3时，该充电控制装置判断对应温度传感器临近的工作模块当前发热非常高，直接控制对应的充电模块停止工作。
当该温度数据介于该温度上限T3与T4之间时，该充电控制装置判断对应温度传感器临近的工作模块当前发热比较高，控制对应的充电模块的充电电流降低50％。
当该温度数据介于该温度上限T4与温度下限T5之间时，该充电控制装置判断对应温度传感器临近的工作模块当前发热正常，控制对应的充电模块102维持原充电电流。
当该温度数据介于该温度下限T5与T6之间时，该充电控制装置判断对应温度传感器临近的工作模块当前发热比较低，控制对应的充电模块的充电电流升高50％。
当该温度数据小于该温度下限T6时，该充电控制装置判断对应温度传感器临近的工作模块当前发热非常低，控制对应的充电模块的充电电流升高100％。
本实施例提出的充电控制方法，可以根据该终端设备中每个位置的实时温度状况动态地控制该终端设备的充电过程，在温度升高时降低对应充电模块的充电电流以降低该充电模块发热，在温度降低时升高对应充电模块的充电电流以恢复正常充电，使得该终端设备在充电的同时不会出现局部温度过高的情况。
参阅图5所示，为图3中步骤S303的第二种流程图。在本实施例中，步骤S501-S503与图4中的步骤S401-S403相类似，区别在于本实施例还包括步骤S504。
S501，当该温度传感器预设范围内的工作模块当前发热较高时，控制对应的充电模块降低充电电流，直到该充电模块停止工作。
S502，当该温度传感器预设范围内的工作模块当前发热较高时，控制对应的充电模块开始工作或者升高充电电流。
S503，当该温度传感器预设范围内的工作模块当前发热正常时，控制对应的充电模块维持原充电电流，即继续按原来的充电电流对电池进行充电。
S504，当部分充电模块(称为目标充电模块)降低或升高充电电流后，控制其他充电模块对该降低或升高充电电流进行补偿，使得该终端设备总体充电电流维持原额定的状态。
例如，当有一个目标充电模块因周围的温度较高而将充电电流降低50mA时，该充电控制装置控制另一个周围温度较低的充电模块将充电电流升高50mA；或者控制另一个周围温度较低且当前未工作的充电模块开始工作，充电电流为50mA；或者控制一组周围温度较低的充电模块升高充电电流，该组充电模块升高的充电电流总和为50mA。
在本实施例中，该充电控制装置可以控制另外一个或一组充电模块对目标充电模块降低或升高的充电电流进行补偿。当控制一组充电模块对该降低或升高的充电电流进行补偿时，可以平均分配补偿的充电电流，也可以根据该组中每个充电模块与目标充电模块的距离或每个充电模块周围的温度数据等条件按照预定比例分配补偿的充电电流。
例如，当有一个充电模块A因周围的温度较高而将充电电流降低60mA
时，该充电控制装置控制一组周围温度较低的充电模块升高充电电流。假设该组充电模块包括两个充电模块B和C，其中，充电模块B与该充电模块A的距离较近，而充电模块C与该充电模块A的距离较远。该充电控制装置控制充电模块B将充电电流升高20mA，控制充电模块C将充电电流升高40mA。或者，假定充电模块B周围的温度高于充电模块C周围的温度，该充电控制装置控制控制充电模块B将充电电流升高20mA，控制充电模块C将充电电流升高40mA。
可以理解，在其他实施例中，该充电控制装置还可以根据设定和当前状况采取其他合理的方式来使该终端设备总体充电电流维持原额定的状态。
本实施例提出的充电控制方法，可以通过多个充电模块之间相互的电流补偿，保持该终端设备的总体充电电流维持原额定的状态，从而避免影响该终端设备的充电速度。
在一个可选实施例中，可以结合详细数据，针对该方法的整体流程进行说明。图6所示为该可选实施例中温度数据和充电电流之间的对应关系曲线。其中横轴表示充电电流(单位：mA)，竖轴表示温度数据(单位：℃)。该方法的流程包括如下步骤：
当监测到充电接口连接上充电器时，启动充电控制功能。假定每个充电模块的设定充电电流是1000mA，整个终端设备中使用了三个充电模块。此时各个充电模块均开始以设定充电电流1000mA将充电器上输入的电能转换输出充入到电池上，每个温度传感器开始实时监测对应充电模块周围的温度数据，并发送给该充电控制装置。
当第一充电模块周围的温度T被监测到大于第一温度上限T4，但小于第二温度上限T3时(T4<T<T3)，将该第一充电模块的充电电流降低50％，即只提供500mA的充电电流。然后如果其他两个充电模块周围温度没有超过第一温度上限T4，这时将第一充电模块降低的500mA充电电流，平均分配到其他两个充电模块上。这样，第一充电模块的充电电流为500mA，第二充电模块和第三充电模块的充电电流为1250mA。
经过固定时间间隔t后，继续监测每个充电模块周围的温度。如果第一充电模块周围的温度T继续上升，并且超过第二温度上限T3(T>T3)，此
时控制该第一充电模块停止工作。然后如果其他两个充电模块周围温度依旧没有超过第一温度上限T4，则将第一充电模块降低的500mA充电电流再分配到其他两个充电模块上。即此时第二充电模块和第三充电模块的充电电流为1500mA。
然后继续每隔时间间隔t监测每个充电模块周围的温度。如此不断监测并对充电电流进行再分配。直到某个充电模块上的充电电流达到其可以支持的最大充电电流后，不再增加。此时整个终端设备的发热情况已经比较严重，所以减掉部分充电电流来降低整机过热的风险。
相反，如果此时监测到第一充电模块周围的温度T小于第一温度下限T5，但大于第二温度下限T6(T6<T<T5)，将其他两个充电模块上之前增加的充电电流总和的50％，重新增加到第一充电模块上。即此时第一充电模块的充电电流为500mA，第二充电模块和第三充电模块的充电电流为1250mA。
然后继续在固定时间间隔t后监测各个充电模块周围的温度。当监测到第一充电模块周围的温度T小于第二温度下限T6时(T<T6)，将其他两个充电模块上之前增加的充电电流全部重新增加到该第一充电模块上。即此时三个充电模块的充电电流均为1000mA，恢复到最初充电的状态。
下面再结合应用场景对该方法的一个可选实施例的整体流程进行说明。
用户将一个终端设备(如手机)正常充电，该手机的充电控制装置启动充电控制功能。每个充电模块均开始以设定电流将充电器上输入的电能转换输出充入到电池上，每个温度传感器开始实时监测对应充电模块周围的温度数据，并发送给该充电控制装置。此时该手机的每个充电模块周围的温度基本都处于预设阈值以下，可以正常工作。
而某一段时间用户使用该手机的无线上网功能浏览网页，这时该手机的射频发射模块启动工作。该射频发射模块工作中会消耗较大电流，使得模块本身发热，并带动模块周围环境温度一起逐渐提高。这时临近该射频发射模块的温度传感器将此温度数据发送给充电控制装置。充电控制装置控制该射频发射模块附近的充电模块逐步降低充电电流，以降低该充电模块的发热，直到关闭该充电模块。这样该手机的外部感受温度，就不会因为该射频发射模块和该充电模块同时工作而局部温度过高。
同时，充电控制装置将远离该射频发射模块的其他充电模块的充电电流适当升高，保持总体充电电流不降低，维持原额定的状态，使得该手机的充电速度不受影响。
当用户停止使用该手机浏览网页后，该射频发射模块停止工作，周围环境温度逐渐降低。临近该射频发射模块的温度传感器将温度降低的状态反馈给充电控制装置。该充电控制装置随即逐步提高该射频发射模块附近的充电模块的充电电流到正常充电状态。同时将远离该射频发射模块的其他充电模块的充电电流同步降低，依然保持总体充电电流不变。
因此，该充电控制装置可以根据实时温度状况动态地控制该手机的充电过程，使得该手机不会出现局部温度过高的情况。同时，还可以通过多个充电模块之间相互的电流补偿，保持该手机的总体充电电流维持原额定的状态，以避免影响该手机的充电速度。
需要说明的是，在本文中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者装置不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到上述实施例方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件来实现，但很多情况下前者是更佳的实施方式。基于这样的理解，本发明实施例的技术方案本质上或者说对相关技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括多个指令用以使得一台终端设备(可以是手机，计算机，服务器，空调器，或者网络设备等)执行本发明实施例所述的方法。
