图 1为本发明电池的一个实施例的结构示意图， 如图 1所示， 本实施例的 电池包括电路板 10和电芯 11 , 其中， 电路板 10包括： 第一触点 101、 第二触 点 102、 第三触点 103、 第四触点 104、 电池管理模块 105和控制开关 106。
具体的， 第一触点 101与电池管理模块 105相连接， 并与上一级电池电气 连接或者用电负载相连接， 用于将电池的电芯 11 的容量或者电池中的电芯 11 的容量和在电池后面级联的电池中的电芯的容量上报给上一级电池或者用电负 载； 第二触点 102, 与电池管理模块 105相连接， 并与下一级电池电气连接， 用 于接收在电池后面级联的电池中的电芯的容量， 并将该在电池后面级联的电池 中的电芯的容量输出给电池管理模块 105;第三触点 103与上一级电池或者用电 负载相连接， 用于在控制开关 106打开时， 与电池中的电芯 11相连接， 以供电 池的电芯 11充电或者放电； 第四触点 104与下一级电池相连接， 用于在控制开 关 106关闭时， 与第三触点 103相连接， 以供下一级电池执行相应的处理； 电 池管理模块 105 , 与电芯 11、 第一触点 101、 第二触点 102和控制开关 106相连 接， 用于根据获取到的电芯 11 的容量和 /或在电池后面级联的电池的电芯的容 量， 触发控制开关 106打开或者关闭。
其中， 控制开关 106可以为模拟开关或者小体积继电器。
在本实施例中， 通过设置在电池上的管理模块根据获取到的在电池后面级 联的电池中的电芯的容量和 /或本电池的电芯的容量，触发控制开关打开或关闭， 以将所述第三触点与电池的电芯相连接或者将所述第三触点与第四触点相连 池充放电， 进而解决了现有技术中电池不适合应用在便携式且小型化的用户设 备上， 以及切换时间较长的问题， 实现了可以根据用户使用的场景不同， 灵活 地配置电池容量。
进一步的， 在本发明的另一个实施例中， 在上述图 1 所示的实施例的基础 上， 以电池管理模块 105 未检测到外部充电电压为例， 详细介绍本实施例的技 术方案， 在本实施例中， 用电负载可以级联至少一个电池， 具体的， 以用电负 载直接级联的电池为例， 当电池管理模块 105 未检测到外部充电电压时， 即说 明电池处于放电状态， 此时， 该电池可以有如下几种工作方式：
第一种， 当电池管理模块 105判断出电芯 11的容量大于等于第一预设容量 时， 说明该电池可以给用电负载供电， 则触发控制开关 106打开， 以将第三触 点 103与电芯 11相连接， 由于第三触点 103与用电负载相连接， 因此， 在第三 触点 103与电芯 11相连接时， 电芯 11可以通过第三触点 103与用电负载相连 接， 从而实现该电池中的电芯 11对用电负载供电；
第二种， 当电池管理模块 105判断出电芯 11的容量小于等于第一预设容量 以及获取到在电池后面级联的电池中的电芯的容量时， 说明该电池中的电芯 11 的容量不足， 无法向用电负载供电， 则触发控制开关 106 闭合， 以将第三触点 103与第四触点 104相连接，从而实现由在电池后面级联的电池中的任一个电池 中的电芯向用电负载供电。 举例来说， 当电池管理模块 105触发控制开关 106 闭合后， 则第三触点 103与第四触点 104相连接， 即本电池中的第四触点 104 与下一级电池中的第三触点相连接， 从而实现有在电池后面级联的电池中的仁 一个电池中的电芯向用电负载供电。 值得注意的是， 此时并不考虑在电池后面 级联的电池中的电芯的容量是否充足， 即是否可以向用电负载供电；
第三种，当电池管理模块 105判断出电芯 11的容量小于等于第一预设容量， 且未获取到在电池后面级联的电池中的电芯的容量时， 则说明本实施例的电池 是该用户设备的最后一级电池电池， 也说明了用户设备中已经没有向用户负载 供电的电池了， 则通过第一触点输出电池耗尽的信号， 并通过前几级电池的第 二触点和第一触点一级一级传输， 直至用户设备接收该电池耗尽的信号， 并根 据该电池耗尽的信号执行关机动作。
更进一步的， 在本发明的又一个实施例中， 在上述图 1 所示实施例的基础 上， 以电池管理模块 105检测到外部充电电压为例， 详细介绍本实施例的技术 方案， 在本实施例中， 当电池管理模块 105检测到外部充电电压时， 即说明电 池处于充电状态， 此时， 该电池可以有如下几种工作方式：
第一种， 当电池管理模块 105 判断出在电池后面级联的电池中的任何一个 电池中的电芯的容量小于第二预设容量， 即与在该电池后面级联的各级电池中 至少有一个电池中的电芯容量不足时， 则触发控制开关 106 关闭， 以将第三触 点 103与第四触点 104相连接， 从而实现优先为在电池后面级联的电池中的电 芯容量不充足的电芯充电。值得注意的是，此处不考虑电芯 11的容量是否充足； 第二种， 当电池管理模块 105判断出电芯 11的容量小于第二预设容量以及 在电池后面级联的电池中的电芯的容量均大于等于该第二容量， 即与在该电池 后面级联的电池中的电芯的容量均充足时， 则触发控制开关 106打开， 以将第 三触点 103与电芯 11相连接， 实现对本电池中的电芯 11的充电；
第三种， 当电池管理模块 105判断出电芯 11的容量大于等于第二预设容量 时， 则说明该电芯 11的容量充足， 若该电池直接与用电负载相连接， 则通过第 一触点 101 向用户设备输出充电完成信号， 以通知该用户设备上的所有电池均 充电完成； 若该电池与上一级电池电气连接， 则通过第一触点 101 向上一级电 池输出充电完成信号， 上一级电池通过第二触点接收到该充电完成信号后， 传 输给其电池管理模块， 由该电池管理模块触发其控制开关打开， 以以断开其第 三触点与其第四触点的连接， 从而断开上一级电池与本电池的连接， 同时， 还 可以实现对上一级电池组件中电池中的电芯充电， 其实现原理与本电池中第一 电芯 11的充电原理相同， 此处不再赘述。
更进一步的， 图 2为本发明电池的又一个实施例的结构示意图， 如图 2所 示， 在上述各个实施例的基础上， 该电路板 10还包括： 第五触点 107和第六触 点 108。 其中， 第五触点 107与电池管理模块 105相连接， 并与上一级电池电气 连接， 用于输出电池中电芯的温度； 第六触点 108, 与电池管理模块 105和第五 触点 107相连接， 并与下一级电池电气连接， 用于接收该下一级电池中电芯的 温度。
具体的， 电池管理模块 105获取电芯 11的温度， 以判断该电芯是否工作在 正常温度下， 举例来说， 当电芯 11 的温度大于电芯 11正常工作的温度的范围 时， 触发控制开关 106关闭， 以停止电芯 11的充电或者放电； 当电芯 11的温 度返回到电芯 11正常工作的温度的范围时， 触发控制开关 106打开， 使得电芯 11继续充电或者放电。
另外， 由于第五触点与上一级电池中的第六触点相连接， 因此， 电池管理 模块 105可以通过第五触点和上一级电池的第六触点将电芯 11的温度传输给上 一级电池， 上一级电池还可以通过第五触点将该电芯 11的温度传输给再上一级 电池或者用电负载。
进一步的， 该电池还包括： 第七触点 109和第八触点 110。 其中， 第七触点 109用于作为接地管脚， 与电芯 11的负极相连接， 并与上一级电池组件电气连 接； 第八触点 110与电芯 11的负极和第七触点 109相连接， 并与下一级电池组 件电气连接。
图 3为本发明电池组件的一个实施例的爆炸图， 如图 3所示， 本实施例的 电池组件包括： 下壳 21、 第一触点组 22、 卡位块 23、 上壳 24、 第二触点组 25、 第一滑槽 26、 第二滑槽 27和电池， 其中， 电池包括电路板 281和电芯 282。
具体的， 该电池可以为上述各实施例所示的电池； 该卡位块 23的材料可以 为聚曱醛（Polyoxymethylene; 简称： POM ) , 更为具体的， 如图 3所示， 该卡 位块 23设置在下壳 21的槽口上， 并与上壳 24的槽口相固定， 从而可以将下壳 21和上壳 24之间的电芯和电路板 10锁定。
在本实施例中， 以电池为如图 2所示实施例中的电池为例， 第一触点组 22 设置在上壳 24上， 包括四个凸出的镀金触点， 分别与前述第二触点、 第四触点、 第六触点和第八触点相连接； 第二触点组 25设置在下壳 21上， 包括四个凹进 去的镀金触点， 分别与前述第一触点、 第三触点、 第五触点和第七触点相连接； 第一滑槽 26设置在上壳 24上， 第二滑槽 27设置在下壳 21上， 且第一滑槽 26 和第二滑槽 27互补。
需要说明的是， 在本实施例中， 还可以通过螺钉代替滑槽实现对上壳 24和 下壳 21之间的连接以及电池组件之间的连接。
在本实施例中， 由于第一触点、 第三触点、 第五触点和第七触点带电， 因 此，第二触点组 25中设置的四个凹进去的镀金触点可以有效地避免短路的风险。 另外， 由于每个电池组件中的第一滑槽 26和第二滑槽 27互补， 因此， 后一级 电池组件中的下壳上设置的第二滑槽可以滑动到前一级电池组件中的上壳上设 置的第一滑槽中， 从而实现了后一级电池组件与前一级电池组件的级联。
还需要说明的是， 第一触点组 22和第二触点组 25在位置上处于相对应的 位置， 从而可以保证了后一级电池组件与前一级电池组件对接时， 后一级电池 组件中的第一触点组和前一级电池组件中的第二触点组能够连接。
进一步的， 为了保证电池组件之间的可靠连接以及无需工具拆卸， 该电池 组件还可以包括锁扣按钮 29, 具体的， 当该组件需要与其后一级的电池组件连 接时， 需要扳动该组件上的锁扣按钮 29, 以实现将该两级电池组件锁住， 从而 避免意外断电。 另外， 在需要取下后一级电池组件时， 可以再次扳动该组件上 的锁扣按钮 29, 以使两级电池组件顺利脱落。
在本实施例中， 电池组件中的电池通过在其上设置的电池管理模块根据获 取到的在电池后面级联的电池中的电芯的容量以及本电池中的电芯的容量， 触 发控制开关打开或关闭， 以将第三触点与本电池中的电芯相连接或者将第三触 任一个电池中的电芯的充放电， 进而解决了现有技术中电池不适合应用在便携 式且小型化的用户设备上， 以及切换时间较长的问题， 实现了可以根据用户使 用的场景不同， 灵活地配置电池容量。
图 4为本发明用户设备的一个实施例的结构示意图， 如图 4所示， 本实施 例的用户设备包括用电负载 31 , 还包括至少一个电池组件 32, 其中该电池组件 可以为图 3所示实施例中的电池组件。
进一步的， 该用户设备还可以包括一个后盖 33 , 该后盖 33可以用于最后一 级的电池组件上， 以对最后一级电池组件中的第一触点组进行保护， 另外， 在 夕卜 ί见上也更力口美 ί见。
更进一步的， 该电池组件 32之间可以采用层叠连接方式级联， 还可以采用 长度上的连接方式级联。
在本实施例中， 当用户不需要用户设备能够长时间工作时， 该用户设备可 以设置一个电池组件； 当用户需要用户设备能够长时间工作时， 可以根据具体 的使用场景多设置几个电池组件， 以增加用户设备的工作时间。
举例来说， 以用户设备上的用电负载 31级联 3个电池组件 32, 且 3个电池 组件 32之间采用层叠连接方式级联为例， 详细介绍本实施例的技术方案。 图 5 为本发明用户设备中用电负载 31与 3个电池组件 32级联的工作原理图， 图 6 为本发明用户设备中用电负载 31与 3个电池组件 32级联的结构示意图，如图 5 和图 6所示， 与用电负载 31级联的电池组件 32可以作为第一级电池组件， 与 该第一级电池组件级联的电池组件 32则可以作为第二级电池组件， 与该第二级 电池组件级联的电池组件 32可以作为第三级电池组件。 其中， 第一级电池组件 中的第一触点、 第三触点、 第五触点和第七触点与用电负载 31电气连接， 第二 触点、 第四触点、 第六触点和第八触点与第二级电池组件中的第一触点、 第三 触点、 第五触点和第七触点电气连接， 第二级电池组件中的第二触点、 第四触 点、 第六触点和第八触点与第三级电池组件中的第一触点、 第三触点、 第五触 点和第七触点电气连接。
进一步的， 图 7a、 7b和 7c分别为本发明三级电池组件一个实施例的工作状 态示意图， 在本实施例中， 以控制开关为模拟开关， 用户设备在使用之前， 三 级电池组件中电池中的电芯容量充足为例， 详细介绍本实施例的技术方案。 如 图 7a所示， 当每一级电池组件中的电芯容量充足时， 用户设备中每一级电池组 件中的电池向用电负载供电的工作原理为： 在第一级电池组件中， 当电池中的 电池管理模块未检测到外部充电电压， 且电芯的容量大于等于第一预设容量时， 触发控制开关打开， 即第三触点与电芯相连接； 另外， 在第二级电池组件和第 三电池组件中， 由于各自的电池管理模块也未检测到外部充电电压， 且电芯容 量大于等于第一预设容量时， 触发控制开关打开， 即第三触点与电芯相连接， 但是由于第一级电池组件中电池的第三触点没有与第四触点相连接， 因此， 第 二级电池组件和第三电池组件无法与用电负载 31相连接， 换言之， 目前由第一 级电池组件中的电池向用电负载 31供电。
如图 7b所示， 在第一级电池组件中， 当电池管理模块未检测到外部充电电 压， 且电芯的容量小于该第一预设容量以及获取到下一级电池组件（即第二级 电池组件） 中电池中的电芯的容量时， 则电池管理模块触发控制开关关闭， 即 第三触点与第四触点相连接， 同时， 由于第二级电池组件中， 电池中的第三触 点与电芯相连接， 因此， 由第二级电池组件中的电池向用电负载 31供电。
如图 7c所示， 在第二级电池组件中， 当电池管理模块未检测到外部充电电 压， 且电芯的容量小于该第一预设容量以及获取到下一级电池组件（即第三级 电池组件） 中电池中的电芯的容量时， 则电池管理模块触发控制开关关闭， 即 第三触点与第四触点相连接， 同时， 由于第三级电池组件中， 电池中的第三触 点与电芯相连接， 因此， 由第三级电池组件中的电池向用电负载 31供电。
另外， 在第三级电池组件中， 当电池管理模块判断出电芯的容量小于第一 预设容量时， 且第二触点没有接收到下一级电池组件中的电池中的电芯的容量 时， 即说明不存在下一级电池组件， 则说明本级电池组件是最后一级电池组件， 则第三级电池组件通过第一触点发送电池耗尽的信号给第二级电池组件中的第 二触点， 再由其第一触点转发给第一级电池组件中的第二触点， 最后由其第一 触点将该电池耗尽的信号给用电负载 31 , 从而使得用户设备获知所有电池组件 中的电池中的电芯的容量均已耗尽， 从而执行自动关机动作。
更进一步的， 图 8a、 8b和 8c分别为本发明三级电池组件另一个实施例的工 作状态示意图， 在本实施例中， 以控制开关为模拟开关， 用户设备中三级电池 组件中电池中的电芯容量不充足， 即需要充电为例， 详细介绍本实施例的技术 方案。 如图 8a所示， 当对用户设备进行充电时， 用户设备中每一级电池组件中 的电池充电的工作原理为： 在第三级电池组件中， 当电池中的电池管理模块检 测到外部充电电压， 且电芯的容量小于第二预设容量时， 触发控制开关打开， 即第三触点与电芯相连接； 另外， 在第一级电池组件和第二级电池组件中， 由 于各自的电池管理模块也检测到外部充电电压， 且判断出后面的各级电池组件 中电池中的电芯的容量小于该第二预设容量时， 则触发控制开关闭合， 即第三 触点与第四触点相连接， 此时， 由于第一级电池组件中电池的第三触点与第四 触点相连接， 第二级电池组件中电池的第三触点与第四触点相连接， 第三级电 池组件中电池的第三触点与电芯相连接， 因此， 可以为第三级电池组件中的电 池优先充电。
如图 8b所示，在第三级电池组件中， 当电池管理模块检测到外部充电电压， 且电芯的容量大于等于该第二预设容量时， 则电池管理模块通过第一触点发送 充电完成的信号给第二级电池组件中的电池中的电池管理模块， 第二级电池组 件中的电池管理模块在接收到该充电完成的信号后， 触发控制开关打开， 即第 三触点与电芯相连接， 由于此时电芯的容量小于第二预设容量， 且接收到该充 电完成的信号， 即判断出第三级电池组件中的电池中的电芯容量大于等于第二 预设值时， 可以为第二级电池组件中的电池充电。
如图 8c所示，在第二级电池组件中， 当电池管理模块检测到外部充电电压， 且电芯的容量大于等于该第二预设容量时， 则电池管理模块通过第一触点发送 充电完成的信号给第一级电池组件中的电池中的电池管理模块， 第一级电池组 件中的电池管理模块在接收到该充电完成的信号后， 触发控制开关打开， 即第 三触点与电芯相连接， 由于此时电芯的容量小于第二预设容量， 且接收到该充 电完成的信号， 即判断出第二级电池组件中的电池中的电芯容量大于等于第二 预设值时， 从而可以为第一级电池组件中的电池充电。 另外， 值得注意的是， 在第一级电池组件中， 当电池管理模块判断出电芯的容量大于等于第二预设值 时， 则通过第一触点发送充电完成信号给用电负载 31 , 从而使得用电负载 31认 为所有电池组件中的电池均充电完成。
在本实施例中， 在用户设备工作时， 各级电池组件可以采用分布式控制， 即每组电池组件中的电池中的电池管理模块通过判断自身电芯的容量以及下一 级电池组件中的电池中的电芯的容量， 实现第三触点与电芯相连接或者第三触 点与第四触点相连接， 同时， 各级电池组件中的电池独立工作， 其电芯不是并 联供电也不是串联供电， 从而更加有利于保护电芯。 并有效地实现了用户设备 中的各级电池组件中的电池迅速切换， 且非常智能化的充放电。
本领域普通技术人员可以理解： 实现上述方法实施例的全部或部分步骤可 以通过程序指令相关的硬件来完成， 前述的程序可以存储于一计算机可读取存 储介质中， 该程序在执行时， 执行包括上述方法实施例的步骤； 而前述的存储 介质包括： ROM、 RAM, 磁碟或者光盘等各种可以存储程序代码的介质。
最后应说明的是： 以上实施例仅用以说明本发明的技术方案， 而非对其限 制； 尽管参照前述实施例对本发明进行了详细的说明， 本领域的普通技术人员 应当理解： 其依然可以对前述各实施例所记载的技术方案进行修改， 或者对其 中部分技术特征进行等同替换； 而这些修改或者替换， 并不使相应技术方案的 本质脱离本发明各实施例技术方案的精神和范围。
