本发明实施例的移动终端，其保存模块在移动终端关机或者电池电量信息发生变化时，就会将当前的电池电量信息保存于移动终端的存储设备中，这样，获取模块在移动终端开机时，而且检测到存储设备中保存有的电池电量信息时，就可直接获取存储设备中的电池电量信息。移动终端就可依据该电池电量信息提供给其他功能模块实现其预定的功能，如电池剩余电量的显示等。如此，节省了开机时计算的过程，就避免了其引起的计算结果具有较差的准确性，计算有一定时间的滞后以及影响系统运行效率等问题。
附图概述
图1表示本发明实施例的移动终端的结构示意图；
图2表示本发明实施例的移动终端的电池结构示意图；
图3表示本发明实施例的移动终端电池电量信息保存方法的步骤流程图；
图4表示本发明实施例的移动终端电池电量信息保存方法的应用示意图。
本发明的实施方式
下面将结合附图对本发明的实施方式进行详细描述。
采用库仑计电池管理的智能移动终端，每次开机过程中都需重新收集电池的各种参数计算电池剩余容量，但是根据电池的特性，在电池启用的过程中其电压和电流并不稳定，从而计算得到结果的就具有较差的准确性，而且开机中操作系统启动的同时进行电池剩余容量的计算，会使计算有一定时间的滞后，影响系统运行效率。本发明实施例提供一种移动终端，能够在开机时直接获取存储的电池电量信息，避免开机过程需重新收集电池的各种参数计算电池剩余容量引起的各种问题。
如图1所示，本发明实施例的一种移动终端，所述移动终端具有存储电池电量信息的存储设备，所述移动终端包括：
保存模块10，设置为：在所述移动终端关机或者电池电量信息发生变化时，将当前电池电量信息保存于所述存储设备中；
获取模块20，设置为：在移动终端开机时，检测到存储设备中保存有电池电量信息时，获取所述电池电量信息。
上述的本发明实施例的移动终端，其保存模块10在移动终端关机或者电池电量信息发生变化时，就会将当前的电池电量信息保存于移动终端的存储设备中，这样，获取模块20在移动终端开机时，而且检测到存储设备中保存有的电池电量信息时，就可直接获取存储设备中的电池电量信息。移动终端就可依据该电池电量信息提供给其他功能模块实现其预定的功能，如电池剩余电量的显示等。如此，节省了开机时计算的过程，就避免了其引起的计算结果具有较差的准确性，计算有一定时间的滞后以及影响系统运行效率等问题。
其中，电池电量信息包括电池剩余电量，当然电池电量信息中还有可能包括有电池最大充电电压和最大充电电流等信息，以满足移动终端上个功能模块的需要。因此，电池电量信息中的内容是可根据移动终端内功能模块的需求进行预定义设置的。
存储设备的设置位置是有多种实现方式的，可以是设置在移动终端的内部电路板上或者移动终端的电池内，在本发明的实施例中，所述存储设备设 置于所述移动终端的电池中。
以一设置在移动终端电池上的电池信息管理芯片为例，该电池信息管理芯片能够作为一存储设备存储电池电量信息，该电池信息管理芯片与传统的电池电路部分相对独立，通过与移动终端的数据通讯完成电池电量信息的读写。如图2所示，移动终端电池在原有的电芯和保护电路的基础上增加了一电池信息管理芯片，电池信息管理芯片具有供电PWR端，地GND端，时钟CLK端和数据总线Databus端，而原有的电芯和保护电路部分具有电压Vbat端，温度THM端，电池地址ID端和地GND端。
在本发明实施例中，存储设备设置于移动终端的电池中，以使得在移动终端更换电池后或者电池应用到另外的移动终端，移动终端能够得知更换后电池的电池电量信息，不会出现移动终端存储的原电池的电池电量信息与更换后电池的电池电量信息不符的情况。而存储设备设置在移动终端的内部电路板上的实现方式，更适用于机身与电池为集合一体的移动终端。
在移动终端或电池第一次使用时，存储设备并没有存储电池电量信息，所以，为了避免移动终端开机时无法得到电池电量信息，给用户使用带来不便，在本发明实施例中，所述获取模块20还设置为：在移动终端开机时，未检测到存储设备中的电池电量信息时，根据所述移动终端的电池电路的参数信息，获得电池电量信息，并将所述电池电量信息保存于所述存储设备中。
在移动终端开机时，未检测到存储设备中的电池电量信息时，获取模块20还能够根据移动终端的电池电路的参数信息来获得电池电量信息，并将其保存于存储设备中。从而在移动终端或电池第一次使用时，也能够得到电池电量信息，提升用户体验。
移动终端开机完成后，随着移动终端的耗电或者充电，电池的真实电池电量信息会随之发生改变，此时，获取模块在开机时获取的电池电量信息已不能满足移动终端的需要。而为了保证电池电量信息的真实与可靠，在本发明实施例中，所述获取模块还设置为：在移动终端开机后，周期性地获取所述移动终端的电池电路的参数信息，并根据所述移动终端的电池电路的参数信息，获得电池电量信息，并判断所述电池电量信息相对于存储设备中存储的电池电量信息是否发生变化。
参数信息的获取周期可以根据移动终端中功能模块的需要进行预定义，对于信息的实时性要求严格的情况下可以缩短周期，对实时性要求较低的情况就可以定义一较长时间的周期。开机后，获取模块能够根据周期性获得的电池电路的参数信息进而获得电池电量信息，并判断获得的该电池电量信息性对于存储设备中存储的电池电量信息是否发生变化。由于有时在周期定义较短的情况下，可能会出现电量并没有发生变化，就不需要对存储设备中的信息进行更新，因此，要判断获得的该电池电量信息性对于存储设备中存储的电池电量信息是否发生变化，随后，保存模块就能够将确认变化的电池电量信息更新到存储设备中，实现数据信息的真实与可靠。
获取模块根据移动终端的电池电路的参数信息，获得电池电量信息的实现方式是多种多样的，例如通过利用电池电路的参数信息中的电池电流，对流入/流出电池的总电流持续进行积分来获得剩余电量及相关的电池电量信息。上述方案的实现过程较为复杂，在本发明实施例中，采用如下实现方式得到电池电量信息：
所述电池电路包括：电池的电芯和保护电路，所述参数信息包括所述电芯的电池电压；
所述获取模块根据所述移动终端的电池电压，从所述移动终端中预先建立的电池电压电量转换表中，获得对应的电池电量信息。
电池电压和剩余电量之间有一确定关系，得到电池端电压即可得到剩余电量，本发明实施例的方案，移动终端内预先建立有电池电压电量转换表，这样，在移动终端获取到电池电压后，就能够从电池电压电量转换表中获得对应的电池电量信息，方便快捷。
综上所述，本发明实施例的移动终端，保存模块在移动终端关机或者电池电量信息发生变化时，就会将当前的电池电量信息保存于移动终端的存储设备中，获取模块在移动终端开机时，而且检测到存储设备中保存有的电池电量信息时，直接获取存储设备中的电池电量信息，节省了开机时计算的过程，从而避免了其引起的计算结果具有较差的准确性，计算有一定时间的滞后以及影响系统运行效率等问题。而且，获取模块能够在开机后，周期性地得到电池电量信息更新存储设备中的信息，保证数据信息是真实与可靠。

步骤11，在所述移动终端关机或者电池电量信息发生变化时，将当前电池电量信息保存于所述存储设备中；

根据所述移动终端的电池电压，从所述移动终端中预先建立的电池电压电量转换表中，获得对应的电池电量信息。
其中，所述存储设备设置于所述移动终端的电池中。
如图4所示，本发明实施例的移动终端电池电量信息保存方法的应用流程，在移动终端开机即系统启动时，首先执行S401，检测存储设备中是否存储有电池电量信息，在检测到存储设备中保存有电池电量信息时，执行S402，从存储设备中读出电池电量信息，然后执行S403，保存电池电量信息到全局变量供上下文使用，也就是说移动终端保存电池电量信息并将其提供给其他功能模块使用。在开机完成后，为了保证电池电量信息的真实与可靠，S404，周期性重新获取电池电量信息，包括剩余容量，可以先周期性地获取电池的 参数信息，再根据参数信息得到电池剩余容量。S405，判断电池电量信息相对于存储设备中存储的电池电量信息是否发生变化，若没有发生变化不需更新，重复上一步S404，若发生了变化，执行下一步S407，将该新的电池电量信息写入存储设备，并重复S403保存到全局变量。当然，对于第一次使用的电池或移动终端，存储设备内不能事先保存电池电量信息，执行S401后，不能检测到存储设备中保存有电池电量信息，则执行S406，初始化电池电量信息，即获取开机时电池的参数信息，再根据参数信息得到电池电量信息，然后同样执行S407将该新的电池电量信息写入存储设备，并重复S403保存到全局变量。这样，在该移动终端关机前，存储设备能够保存最新得到的电池电量信息，下一次开机，能够读出存储设备中的电池电量信息。
本发明实施例的移动终端电池电量信息保存方法，在移动终端关机或者电池电量信息发生变化时，就会将当前的电池电量信息保存于移动终端的存储设备中。在移动终端开机时，而且检测到存储设备中保存有的电池电量信息时，直接获取存储设备中的电池电量信息，节省了开机时计算的过程，从而避免了其引起的计算结果具有较差的准确性，计算有一定时间的滞后以及影响系统运行效率等问题。而且，在开机后，周期性地得到电池电量信息更新存储设备中的信息，保证数据信息是真实与可靠。
该方法是应用于上述移动终端的方法，上述移动终端的实现方式适用于该方法，也能达到相同的技术效果。
本领域普通技术人员可以理解上述实施例的全部或部分步骤可以使用计算机程序流程来实现，所述计算机程序可以存储于一计算机可读存储介质中，所述计算机程序在相应的硬件平台上(如系统、设备、装置、器件等)执行，在执行时，包括方法实施例的步骤之一或其组合。
可选地，上述实施例的全部或部分步骤也可以使用集成电路来实现，这些步骤可以被分别制作成一个个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。
上述实施例中的装置/功能模块/功能单元可以采用通用的计算装置来实现，它们可以集中在单个的计算装置上，也可以分布在多个计算装置所组成的网络上。
上述实施例中的装置/功能模块/功能单元以软件功能模块的形式实现并作为独立的产品销售或使用时，可以存储在一个计算机可读取存储介质中。上述提到的计算机可读取存储介质可以是只读存储器，磁盘或光盘等。
工业实用性
本发明实施例的移动终端，其保存模块在移动终端关机或者电池电量信息发生变化时，就会将当前的电池电量信息保存于移动终端的存储设备中，这样，获取模块在移动终端开机时，而且检测到存储设备中保存有的电池电量信息时，就可直接获取存储设备中的电池电量信息。移动终端就可依据该电池电量信息提供给其他功能模块实现其预定的功能，如电池剩余电量的显示等。如此，节省了开机时计算的过程，就避免了其引起的计算结果具有较差的准确性，计算有一定时间的滞后以及影响系统运行效率等问题。
