以下结合具体实施例对本发明的实现进行详细描述:
图 1 示出了本发明另一实施例提供的充电方法, 为了便于说明, 仅示 出了与本实施例相关的部分, 详述如下:
步骤 S1 01、 获取电子设备上电池的第一温度。
在本发明实施例中, 可以通过温度传感器监测电子设备上安装的电池 的温度, 其中, 温度传感器一般都安装在电池内部或外部, 温度传感器可 将获取到的电池的温度发送给电子设备的充电管理芯片或者电子设备的主 处理器。
当需要给电池充电时, 可以先通过相应的充电接口给电子设备插上充 电器, 再通过温度传感器获取电池的第一温度, 如果充电管理芯片可以接 收温度传感器获取到的温度信号并进行处理时, 则不需要开启电子设备, 如果充电管理芯片不能够接收温度传感器获取到的温度信号并进行后续处 理时, 这时, 需要开启电子设备, 由电子设备中的主处理器接收温度传感 器获取到的温度信号并进行后续处理。
根据经验, 电池的最佳充电温度范围为 X~丫, 最小值为 X, 最大值为丫。 在对电池进行充电之前, 先获取电池的第一温度, 如果电池的第一温度不 在预设的最佳充电温度范围内, 则执行步骤 S1 02。

在本发明实施例中, 当电池的温度不在预设温度范围内时, 可以开启 电子设备, 并使该电子设备运行于相应的工作模式, 电子设备在不同的工 作模式下产生不同的功耗, 该工作模式是特定的 2-3个工作模式, 也可以是 连续的、 功耗从低到高的多个工作模式, 也可以是对某些器件的关闭或者 运行状态的调节, 只要能导致电子设备的功耗和发热变化, 皆可。 本发明 不限于此。 通过调整电子设备的工作模式, 可以使电子设备内部温度变化, 电池温度^着变化。
其中, 在电池的温度低于预设温度范围内的最小值 X时, 为了保证电池 的温度快速上升到预设温度范围内, 可使电子设备运行于高功耗的工作模 式。
在电池的温度高于预设温度范围内的最大值丫时, 使电子设备运行于低 功耗的工作模式, 这样可以逐渐使电池的温度逐渐降低, 回落至预设温度 范围内, 继续充电。
另外, 在电子设备处于高功耗的工作模式, 并且电子设备工作时间大 于预设的时间阈值 Z时, 可能会使除电池以外的电子设备中的其它器件的温 度升高至它们所不能承受的温度范围, 而导致损坏, 因此, 为了保证电子 设备中的其它器件的正常工作, 需要调整电子设备的工作模式为低功耗的
工作模式, 在低功耗的工作模式下对电池充电或者停止对电池的充电。 如果在预设的时间阈值 Z内, 电池温度低于预设温度范围内的最小值 X, 则使电子设备运行于高功耗的工作模式, 直至电池的温度高于预设温度范 围内的最小值 X。
步骤 S1 03、 获取所述电池的第二温度。
在本实施例中,在获取到的第一温度小于预设的温度范围内的最小值 X 时, 使电子设备运行于高功耗的工作模式, 在电池的温度高于预设温度范 围内的最大值 Y 时, 使电子设备运行于低功耗的工作模式, 从而调整电池 的温度, 这时, 还需要一直获取电池的温度, 当获取到的第二温度在预设 的温度范围内时, 执行步骤 S1 04。
步骤 S1 04、 若所述第二温度在预设的温度范围内, 则对所述电池进行 充电。
在本实施例中, 当第二温度在预设的温度范围内时, 表示电池的温度 到达理想的充电温度范围, 则对电池进行充电。
作为本发明的一个优选实施例, 在步骤 S1 04之后, 还包括: 获取电池 的第三温度, 若第三温度高于预设的温度范围, 则停止充电。
通过这一步, 可以在对电池充电时, 对电池的温度进行检测, 防止电 池的温度过高, 以致超过电池能够承受的最大温度值, 引起爆炸。
另外, 作为本发明的另一个优选实施例, 在步骤 S1 04之后, 还可以包 括: 控制电子设备运行于相应的工作模式, 以使得电子设备上电池的温度 处于预设的温度范围内。
电子设备可以不断调整功耗等级, 运行于相应的工作模式, 从而使电 池的温度保持在预设的温度范围之内。 电子设备的功耗可以分几个等级, 如分三等, 第一级功耗模式约 0. 5W, 第二级功耗约 1 W, 第三级功耗约 2W等, 通过温度检测, 如果温度大于丫, 则调低功耗等级, 如果温度低于 X, 则提 高功耗等级, 这样使电池的温度維持在 ~丫范围内。 其中不同功耗等级, 可
以通过增加或减少发热器件或通过加强或减弱发热器件的工作强度等多种 方式来实现。
以下举一个例子来说明整个电池的充电过程:
先通过相应的充电接口给电子设备插上充电器, 再通过温度传感器获 取电池的第一温度, 如果充电管理芯片可以接收温度传感器获取到的温度 信号并进行处理时, 则不需要开启电子设备, 直接由充电管理芯片判断第 一温度是否低于预设温度范围内的最小值 X, 如果是, 则开启电子设备, 使 电子设备运行于高功耗的工作模式, 直至通过温度传感器获取到的电池的 第二温度大于预设温度范围内的最小值 X, 这时, 则使整个电子设备处于一 定功耗的工作模式下, 使电池的第二温度維持在最小值 X与最大值丫之间, 对电池充电, 一直充满为止。
如果充电管理芯片不能够接收温度传感器获取到的温度信号并进行后 续处理时, 这时, 需要开启电子设备, 由电子设备中的主处理器接收温度 传感器获取到的温度信号, 并根据该温度信号判断第一温度是否低于预设 温度范围内的最小值 X, 如果是, 则开启电子设备, 使电子设备运行于高功 耗的工作模式, 直至通过温度传感器获取到的电池的第二温度大于预设温 度范围内的最小值 X,这时,则使整个电子设备处于一定功耗的工作模式下, 使电池的第二温度維持在最小值 X与最大值丫之间, 对电池充电, 一直充满 为止。
本实施例, 先获取电子设备上电池的第一温度; 若所述第一温度不在 预设的温度范围内, 则控制所述电子设备运行于相应的工作模式, 所述电 子设备在不同的工作模式下产生不同的功耗; 再获取所述电池的第二温度; 若所述第二温度在预设的温度范围内, 则对所述电子设备进行充电。 电子 设备在不同的工作模式下能够产生不同的功耗, 则电子设备在不同的工作 模式下发热不同, 而电池位于电子设备上, 其温度环境将受到电子设备发 热的影响。 因此根据电池的温度, 调节电子设备的工作模式, 能够实现对
于电池温度环境的调节, 从而使得电池能够在一个理想的温度环境下充电。 另外, 在获取到电池的温度高于预设的温度范围时, 可以停止充电, 对电 池性能不会造成损伤。
本发明实施例还提供了一种计算机程序产品,包括计算机程序代码, 其中当该计算机程序代码被计算机执行时, 会使得该计算机执行上面实 施例的所有步骤。
