Description
一种电子设备的电池识别系统、 方法及电子设备
技术领域
—明 ¾i"T¾ 领域, 尤其涉及一种电 子设备的电池识别系统、 方法及电子设备。
背景技术
目前, 釆用可循环充电电池作为电源的便携式电子设备, 如移动终端, 笔记本电脑, 平板电脑等的市场需求迅猛发展, 而这些电子设备的功能和应 用越来越多, 这就造成耗电量越来越大, 设备对电池容量的需求越来越大。 但由于现有电池技术的限制, 电池的容量往往与电池的体积成正比。 在设备 的电量持续力和便携性上很难两全, 这就造成很多电子设备配有两套甚至多 套可选电池, 在同一设备电池卡槽中对应不同需求时换用不同容量和体积的 电池。 这样的应用同时带来了一些问题, 如对不同容量电池的识别和电量计 算以及电量显示等问题。
锂电池具有高存储能量、 寿命长、 重量轻和无记忆效应等优点, 已经在 现行电子设备中得到了广泛的使用。 mAh是电池容量的计量单位, 具体是电 池中可以释放为外部使用的电子的总数,折合为物理上的标准单位就是库仑。 库仑的国际标准单位为电流乘于时间的安培秒, 即 lmAh=0.001安培 *3600秒 =3.6安培秒 =3.6库仑。
现有的电子设备, 主要有如下三种方法实现电量的计算:
1.直接电池电压监控方法: 直接电池电压监控方法简单易行; 但是该方 法精度较低(20% ) , 且缺乏对电池的有效保护;
2.电池建模方法: 电池建模方法有效地提高电量的测量精度(5% ) , 简 单易用, 无需做电池的初次预估; 但是数据表的建立是一个复杂的过程, 并 且对不同容量或类型的电池的兼容也不好;
3.库仑计检测法: 库仑计可以精确跟踪电池的电量变化, 精度可达 1%; 但是, 库仑计存在电池初次预估的问题, 需要知道额定容量、 当前容量和当
前的电流损耗, 且电流电阻的精度直接影响了电量的精度。
目前, 以库仑计检测法最为准确和有效, 主流的智能手机终端以及平板 电脑等电子设备大多都釆用库仑计检测法, 但是库仑计检测法只能解决固定 容量电池的电量计算和电量显示问题, 对应不同容量的电池, 库仑计检测法 则无法准确计算显示电量。 因此, 如何实现简单、 快捷、 准确的识别不同容 量的电池成为当前需要解决的一个技术难题。

霍尔传感器是根据霍尔效应制作的一种磁场传感器, 是由霍尔元件和它 的附属电路组成的集成传感器。 霍尔效应是在半导体薄片两端通以控制电流 I, 并在薄片的垂直方向施加磁感应强度为 B的匀强磁场, 则在垂直于电流和 磁场的方向上, 将产生电势差为 UH的霍尔电压。 霍尔传感器分为线性型霍 尔传感器和开关型霍尔传感器两种。 线性型霍尔传感器由霍尔元件、 线性放
大器和射极跟随器组成, 其输出模拟量, 输出电压与外加磁场强度呈线性关 系。 线性型霍尔器件主要用于一些物理量的测量, 比如: 电流测量和位移测 量。 开关型霍尔传感器由稳压器、 霍尔元件、 差分放大器, 斯密特触发器和 输出级组成, 它输出数字量。 当外加的磁感应强度超过动作点时, 传感器输 出低电平, 当磁感应强度降到动作点以下时, 传感器输出电平不变, 一直要 降到释放点时, 传感器才由低电平跃变为高电平。 动作点与释放点之间的滞 后使开关动作更为可靠。 因此, 开关型霍尔传感器可用于接近开关、 转数和 车门状态显示等。
由此, 本实施方式提供一种电子设备的电池识别方法, 具体包括: 在所述电子设备中设置霍尔传感器, 并在所述第一容量电池中设置磁感 应件, 且所述第一容量电池处于安装位置时, 所述磁感应件处于所述霍尔传 感器的感应区内;
所述第一容量电池安装到所述电子设备中时, 所述霍尔传感器感应到所 述磁感应件靠近, 则输出用于识别所述第一容量电池的控制信号。
较佳的, 所述霍尔传感器安装在所述电子设备的主板上;
所述磁感应件设置在所述第一容量电池的电池盖上对应所述霍尔传感器 处。
较佳的, 所述磁感应件包括磁铁, 所述磁铁的磁极与所述霍尔传感器的 感应面垂直。
较佳的, 所述霍尔传感器的输出端连接至一处理器,
所述第一容量电池安装到所述电子设备中时, 所述霍尔传感器感应到所 述磁感应件靠近, 向该处理器输出低电平信号; 该处理器根据接收到的所述 低电平信号, 识别出所述电子设备中安装的是所述第一容量电池;
而当未设置磁感应件的第二容量电池安装到所述电子设备中时, 所述霍 尔传感器感应不到磁感应件靠近, 因此向该处理器输出高电平信号; 该处理 器根据接收到的所述高电平信号, 识别出所述电子设备中安装的是所述第二 容量电池。
较佳的, 所述的第一容量电池和所述第二容量电池可以是: 标准容量电
池(薄电池)和大容量电池(厚电池) , 等。
下文中将结合附图对本发明的实施例进行详细说明。 需要说明的是, 在 不冲突的情况下, 本申请中的实施例及实施例中的特征可以相互任意组合。
以手机终端为例, 本发明实施例中, 为了实现识别电子设备中的厚电池 和薄电池两种不同容量的电池, 主要釆用如下方案:
一, 在主板上放置霍尔传感器, 在电池盖上对应霍尔传感器的位置放置 磁铁
如图 1所示, 霍尔传感器 12放置在终端设备的主板 2上。 如图 3所示, 在厚电池的电池盖 31对应霍尔传感器 12的上方处放置磁铁 312。该磁铁 312 的磁极必须要保证跟霍尔器件的感应面垂直, 保证在电池盖 31合上后, 霍尔 传感器 12可以感受的磁场变化, 并能切割磁力线。
另外, 如图 2所示, 为避免干扰磁力线的感应, 在手机后壳上对应霍尔 传感器 12的上方处可设一开口 201。
需要注意的是, 该霍尔传感器 12附近尽量不要有带磁性的器件, 且该霍 尔传感器 12的感应区与电池盖 31上的磁铁 312的极性垂直。 如果磁极与霍 尔传感器 12的感应面平行, 即便电池盖合上后, 霍尔传感器 12依然不能感 受到的磁场变化, 因此传感器无法输出相应的控制信号。
二, 霍尔传感器的输出端连接处理器
如图 4所示, 可将霍尔传感器的输出端连接到处理器的中断管脚或者通 用 I/O口。在电子设备开机过程当中,通过判断该中断管脚或通用 I/O口的状 态, 来确定所用电池的容量, 启用相应的驱动程序。 其中, 不同的电池容量 主要会影响到充电电流和电量显示。
如果电池盖上设有磁铁, 则当电池盖合上时, 磁铁靠近霍尔传感器, 霍 尔传感器受到磁场变化, 并切割磁力线, 则霍尔传感器的输出信号将由高电 平变为低电平。 如果电池盖上没有设置磁铁, 当电池盖合上时, 由于霍尔传 感器没有感应到磁场变化, 则霍尔传感器的输出管脚将保持高电平。 处理器 根据霍尔传感器输出的高低电平, 即可识别出相应类型的电池。
三, 同一个电池腔兼容厚薄两种电池
电子设备的不同容量电池对应于不同厚度的电池时,如图 5和图 6所示, 后壳 1中的电池腔需能兼容薄电池 20和厚电池 30两种不同厚度的电池。 另 夕卜, 在电池的相关位置也要考虑对电池的固定作用。 比如说: 在放入薄电池 时, 后壳相对电池位置要另加结构筋来固定电池; 在放入厚电池时, 后壳相 对电池位置不需要另加结构筋来固定电池。
此外, 需要考虑到电池前面两个定位卡角和结构的配合, 需要保证厚薄 电池的电池卡角的形状和厚度一致。 这样, 才能保证装配的可行性。 薄电池 的电池腔装配图如图 5所示, 厚电池的电池腔装配图如图 6所示。
四、 电池盖的防呆设计
上述实现方案中, 由于针对厚薄两种电池, 分别有厚薄两种电池盖, 因 此, 在电池盖的结构上做了防呆设计, 如图 7和图 8所示, 在厚薄两种电池 盖的不同位置设置有大小相同的筋条 211和 311 , 而在厚薄两种电池上的相 应位置开有缺口。 当盖上电池盖时, 薄电池盖 21上的筋条 211可以嵌入薄电 池 20上的缺口, 而与厚电池的结构干涉; 厚电池盖 31上的筋条 311可以嵌 入厚电池 30上的缺口, 而与薄电池的结构干涉。 这样确保了在手机电池仓中 放入薄电池时, 只能盖上薄电池盖; 在手机电池仓中放入厚电池时, 只能盖 上厚电池盖。
以上仅为本发明的优选实施案例而已, 并不用于限制本发明, 本发明还 可有其他多种实施例, 在不背离本发明精神及其实质的情况下, 熟悉本领域 改变和变形都应属于本发明所附的权利要求的保护范围。
显然, 本领域的技术人员应该明白, 上述的本发明的各模块或各步骤可 以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, 或者分布 在多个计算装置所组成的网络上, 可选地, 它们可以用计算装置可执行的程 序代码来实现, 从而, 可以将它们存储在存储装置中由计算装置来执行, 并 且在某些情况下, 可以以不同于此处的顺序执行所示出或描述的步骤, 或者 将它们分别制作成各个集成电路模块, 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。 这样, 本发明不限制于任何特定的硬件和软件 结合。
工业实用性 本发明实施例的能够识别电子设备中不同容量的电池, 为用户提供了多 种选择, 提高了产品在市场的竟争优势; 同一个电池腔中可以兼容两种不同 容量的电池; 如果客户选择容量较小的薄电池, 可以降低整机成本。
