下面将结合附图, 对本发明的实施例进行详细描述。
请参阅图 1, 为本发明实施例中提供的一种终端的充电方法的流程图, 所述终端 至少包括主设备电源。 在该实施例中, 终端为主设备, 第二终端为从设备。 该方法可 以包括:
- 步骤 101 : 当第二终端与所述终端处于连接状态时, 检测第二终端的电池电量; 以及
-步骤 102: 当第二终端的电池电量小于预设的第一充电阈值时, 控制主设备电源 与第二终端的电池连接, 从而主设备电源给第二终端的电池充电。
在步骤 101中, 检测第二终端的电池电量可以如下进行-
- 所述终端的微处理器通过连接器和系统管理总线获取第二终端的电池的电量状 态; 以及
-判断第二终端的电池的电量状态是否小于预设的第一充电阈值, 若小于, 则执 行步骤 102。
其中, 主设备电源具体可以为: 主设备电源适配器或者主设备电池。
可选的, 当主设备电源为主设备电源适配器, 且主设备电源适配器外接电源时, 该方法还可以包括:

可选的, 当第二终端的电池的电量达到预设的第一充电阈值时, 该方法还可以包 括: 主设备的微处理器判断是否需要为所述终端的电池充电; 若需要, 则执行所述控 制主设备电源与所述终端的电池连接, 主设备电源为所述终端的电池充电的步骤。 可选的, 所述终端可以包括: 笔记本电脑或掌上电脑或移动互联网设备, 或者其 他的便携设备, 本实施例不作限制。 第二终端可以包括: 手机或 MP4, 或者其他的便 携设备, 本实施例不作限制。
在本实施例中, 当主设备插入充电器充电时, 若主设备的微处理器判断需要为从 设备的电池充电时, 则控制主设备的电池充电芯片和电源选择切换芯片为从设备的电 池充电。 其中, 主设备的微处理器可以通过连接器和系统管理总线获取从设备的电池 充电的状态信息; 主设备的微处理器根据从设备的电池充电的状态信息判断是否需要 为从设备的电池充电。 例如, 当主设备的微处理器判断从设备的电池的电量小于预设 的第一充电阈值时, 则控制主设备的电池充电芯片和电源选择切换芯片为从设备的电 池充电。
当主设备的微处理器判断从设备的电池的电量达到预设的第一充电阈值时, 则控 制主设备的电池充电芯片和电源选择切换芯片为主设备的电池充电。

在本发明实施例中, 主设备和从设备可以通过连接器相连, 也可以其他的连接方 式相连, 比如卡接等。 当主设备插入充电器时, 主设备先判断是否需要为从设备的电 池充电, 若需要, 则主设备控制主设备的电源与从设备的电池连接, 从而主设备电源 给从设备的电池充电。 具体地, 主设备的电池充电芯片和电源选择切换芯片可以为从 设备的电池充电。 当判断从设备的电池的电量达到预设的第一充电阈值时, 则控制主 设备的电池充电芯片和电源选择切换芯片为主设备的电池充电。 也就是说, 在主设备 插入充电器的情况下, 优先为从设备的电池充电, 以保证从设备的电池能够尽可能多 的携带电量, 并在在为从设备的电池的电量充电到预定的充电阈值后, 再为主设备的 电池充电。 进一步, 还可以在主设备的电池的电量充电到预定的另一充电阈值 (即, 第二充电阈值) 后, 再为从设备的电池充电, 直至充满, 然后再将主设备的电池充满 电量。 以便于在主设备的电池的电量低的情况下, 从设备的电池可以为主设备供电, 维持主设备工作, 从而方便用户使用, 提高设备的稳定性和易用性。
当然, 由于主设备和从设备各自拥有独立的电池供电子系统, 当主设备和从设备 断开时, 主设备和从设备的电池供电子系统分别独立为主设备和从设备供电。 当主设 备和从设备连接 (比如通过连接器等) 在一起时, 两个独立的电池供电子系统也关联 在一起, 比如通过连接器关联在一起, 但并不限于此。

例如, 对于现有便携设备的电池, 绝大部分为锂离子电池。 对于给锂离子电池的 充电过程,一般情况下分为 CC (恒流, Constant Current)和 CV (恒压 Constant Voltage ) 两个阶段。对于 CC, 是一个恒流的过程, 充电的电流比较大, 充入电池电量的速度比 较快; 而对于 CV, 是一个恒压过程, 充电的电流逐渐减小, 充入电池电量的速度比较 慢。 为了满足需要, 优先为从设备的电池充电, 当从设备的电池的电压达到 CC段与 CV段电压拐点的最高值时,再切换至为主设备的电池充电; 当主设备的电池电压达到 CC段与 CV段电压拐点的最高值时,再切换至为从设备电池进行 CV段充电,直至充满, 之后再切换至为主设备的电池进行 CV段充电, 直至充满。

还请参阅图 10, 为本发明实施例提供的一种主设备和从设备连接状态的结构示意 图。 主设备 11和从设备 12通过连接器 13连接。 在该实施例中, 主设备 11以笔记本电脑 为例, 从设备 12以手机为例, 主设备的微处理器以 EC为例。如图 10所示, 设备 11包括: 主设备的 EC 111、 主设备的电源选择切换芯片 112、 主设备的电池充电芯片 113、 主设 备的电池 114和主设备的直流插座 115。 从设备 12包括: 从设备的 ARM 121、 从设备的 电池充电芯片 122、 从设备的电池 123和从设备的直流插座 124。 这些部件之间的具体 连接关系详见图 10。
在图 10中, 对于主设备 11, 其中标有 Power的线, 为供电线 (Power Bus), 标有 SMBus的线为系统管理数据线 (SMBus, System Management Bus)o 在该实施例中, 系统管理数据线可以是 I2C或 SPI总线, 也可是其它形式的数据通信线。 标有 Control的 线为普通控制线。 EC 111作为主控单元, 会根据预定的充、 放电策略, 控制电源选择 切换芯片 112的选择切换,电池充电芯片 113的充电电压及充电电流参数。同时, EC 111 通过 SMBus总线从主设备 11的电池 114和从设备 12的电池 123获得电池的状态信息, 并 反馈给上层操作系统。
对于从设备 12, 其中 ARM 121为主控芯片, 并且通过数据通讯总线 (可以为双线 SMBus总线、 I2C总线、 单线的串行总线等) 获得从设备电池 123的状态信息。 其中标 有 Power的线路为充电线路, 可以为从设备独立充电, 用于在从设备与主设备脱离的 情况下为从设备电池进行充电。从设备通过物理接口与主设备(笔记本电脑)相连接。
在主设备和从设备分开的状态下, 主设备和从设备电池分别独立进行充放电。 如图 10所示,在主设备和从设备连接的状态下,主设备可为从设备电池进行充电, 并且主设备 EC能够获得从设备电池 123的全部状态信息。 在主设备没有插充电器时, 优先使用主设备电池 114为主、 从设备供电。 当主设备电池 114电量低于预设的第一放 电阈值时或者主设备电池不存在的情况下, 从设备电池 123可以为主设备和从设备供 电。
在主设备和从设备连接状态下, 只能通过主设备充电器为主、 从设备电池进行充 电, 并且优先为从设备电池 123进行充电。 当从设备电池 123充电到预设的第一充电阈 值时,转为对主设备电池 114进行充电。当主设备电池 114充电到预设第二充电阖值时, 再转为继续对从设备电池 123进行充电, 直至充满。 从设备电池 123充满后, 再转为继 续对主设备电池 114进行充电, 直至充满。 主设备无论处于开机和关机的状态, 都可 以为从设备进行充电。 从设备不论开机和关机, 都可以被充电。
在主设备和从设备连接状态下, 如果主设备没有插入充电器充电, 则进行如下操 作。 在开机的时候, 优先使用主设备电池 114为主设备和从设备进行供电。 当主设备 电池 114电量低于预设的第一放电阈值时或者主设备电池不存在的情况下, 从设备电 池 123可以为主设备和从设备供电。 在主设备关机的状态下, 从设备电池 123不为主设 备进行供电, 无论主设备电池 114剩余电量为何种状态。
在主设备和从设备连接状态下, 由 EC收集主设备电池 114和从设备 123的状态信 息, 并由主设备显示给用户。 当主设备电池 114剩余电量低于预设的第一放电阈值时, 主设备在开机的状态下进行告警, 进而进入休眠状态。 当从设备 123的剩余电量低于 预设的第二放电阈值时, 从设备在开机的状态下进行告警, 进而进入休眠状态。 当主 设备电池 114剩余电量低于预设的第一断电阈值时, 主设备电池 114保护性断电。 从设 备 123的剩余电量低于预设的第二断电阈值时, 从设备电池 123保护性断电。
由此可见, 本发明实施例提出了一种合理解决主设备和从设备的两 电池供电子 系统间的充、 放电的问题和策略, 以保证从设备的电池能够尽可能多的携带电能, 并 且在主设备的电池的电能量低的情况下, 从设备的电池可以为主设备供电, 维持主设 备工作, 方便用户使用, 提高设备的稳定性和易用性。
