Description

组合式锂离子电池装置
技术领域
本发明涉及锂离子电池，尤其是锂当量含量超过运输安全当量(一般为8克锂当量)的大容量锂离子电池装置，具体地说是一种可将大当量锂离子电池分成若干低于运输安全当量的小当量锂离子电池既便于携带又不影响其性能更不会产生混用的大当量组合式锂离子电池装置。
背景技术
由于锂离子蓄电池组具有重量轻、容量大的特点，因此电视摄像机和便携式电子设备多采用其作为直流供电电源，然而，随着国际上对航空运输安全的重视，单块锂离子蓄电池组若其容量超过8克锂当量含量就必须按危险品运输，不能直接随身携带乘飞机，这给使用者尤其新闻摄像记者带来诸多限制。首先，由于8克锂当量含量的限制，人们外出为了乘飞机，要么对大容量的锂离子蓄电池组采用专门的危险品包装和昂贵的运费办理托运，要么只能随身携带多块小容量的锂离子蓄电池组，由于小容量蓄电池组供电时间短，电子设备需要频繁更换电池，影响工作效率。第二，有人采取两块小容量的锂离子蓄电池组直接并联使用以提高容量，但是两块并联的小容量锂离子蓄电池组其容量、内阻、外端口的电压、使用次数、新旧程度等参数很难达到匹配一致，这样的简单并联容易损伤电池或造成其它安全隐患。
发明内容
本发明的目的是针对现有的大当量锂离子电池不便于携带乘坐航空器具的问题，发明一种在运输时可以分开携带，在使用时可以组合串联为一体并具有自动识别电池身份的大当量组合式锂离子电池装置。
本发明的技术方案是：
一种组合式锂离子电池装置，其特征是它至少有二个能相互插接并活动相连的盒体组成，每个盒体中串接或并接安装有锂当量总和小于8克的若干锂离子电池，一个盒体中的连接的锂离子电池组与另一盒体中的连接的锂离子电池组之间相互串接或并接相连；在其中一个盒体中安装有识别芯片及由识别芯片控制的报警装置和供电开关，在其余盒体中安装有身份标识芯片，识别芯片中存储有身份标识芯片中的识别标识。
所述的盒体之间通过位于凸起在它们相对面上的燕尾形插槽和燕尾形插块相连，并通过分别设置在相邻的二个盒体上的定位销和定位孔定位锁紧。
所述的身份标识芯片可以是电子标签，在识别芯片中存储有所述的电子标签的内容。
识别芯片还连接有由晶体管Q1、Q2组成的供电开关，以便所插接相连的盒体不一致时自动切断向外的供电回路。
所述的报警装置为蜂鸣器和/或发光二极管。
本发明的有效效果是：
1、本发明采用两块或二块以上可以装配为一体亦可以拆分开的锂离子蓄电池组装置，当这两块配套的蓄电池组装配为一体时，提供强大的电力，当该装置拆分为两块时，每块电池容量都减少一半，各自不能单独工作，可以安全方便地携带其乘坐飞机。
2、本发明采用的两块或两块以上的组合式蓄电池组装置，其内部置有识别身份的智能控制电路，即使多套这样的锂离子蓄电池装置拆分后混放在一起，当装配为一体时，智能控制电路可以识别装配在一起的蓄电池组是否配对，如果不配对则声光报警，并关闭该组合式蓄电池组装置向外供电的回路，有效防止容量、电压不同或新、旧不一的锂离子蓄电池组混用，确保安全。
3、结构简单，安全、实用、可靠。

具体实施方式
下面结构附图和实施例对本发明作进一步的说明。
如图1-5所示。
一种锂当量介于8-16克之间的大当量组合式锂离子电池装置，它有二个能相互插接并活动相连的盒体1、2组成，如图1所示，盒体1、2中串接或并接安装有锂当量总和小于运输安全值(8克锂当量)的若干锂离子电池，如图2所示，盒体1中的连接的锂离子电池组与盒体2中的连接的锂离子电池组之间相互串接相连(根据需要也可设计成并联连接结构)；在其中一个盒体1或盒体2中安装有识别芯片3及由识别芯片3控制的报警装置4和供电开关5，在另一个盒体2或1中安装有身份标识芯片6，识别芯片3中存储有身份标识芯片6中的识别标识，如图7所示。
盒体1与盒体2之间可采用多种机械连接方式加以实现，本实施例的盒体1、2之间通过位于凸起在它们相对面上的凸块7、8上相配的燕尾形插槽9和燕尾形插块10实现面与面之间的连接，并通过分别设置在相邻的二个盒体1、2上的可上下移动的定位销11和定位孔12定位锁紧防止相对面之间的滑动平移，在盒体1、2上还设有电气连接插头13、14，如图3、4、5、6所示。
本实施例的识别芯片3、报警装置4、供电开关5、身份标识芯片6构成了本发明的智能识别控制系统，它可用于判别拆分运输后再组合在一起的二个电池盒体是否原装的，以保证容量、电压、新旧程度的一致性，其原理框图如图7所示，其具体的电路图如图8所示。此外，图8中的身份标识芯片6还可采用电子标签来代替，在识别芯片3中存储有电子标签的全球唯一的代码(即ID码)。
本实施例中的报警装置4采用了声(蜂鸣器)、光(发光二极管)报警，当两个盒体1、2插接到位后，盒体1、2上的电气连接插头13、14使身份标识芯片6与识别芯片3导通，识别芯片3在程序的控制下自动读取身份标识芯片6中的身份标识(出厂时预先写入并不可更改)并与识别芯片3中存储的身份标识相比对，如果一致，则不向与之相连的报警装置4中的三极管Q3和控制供电开关动作的三极管Q2发送动作信号，如果不一致，则立即使三极管Q2、Q3导通，Q2立即使作为开关的三极管Q1截止，切断通向接口的电源回路，终止供电，Q2同时使发光二极管D1导通，发出报警光，Q3导通使蜂鸣器LS1发出声音，通知使用者目前所配接的两个盒体不属于同一电池组，不能正常使用，必须更换到原配的盒体才能正常工作。如果不安装作为供电开关5的晶体管Q1则连接的电池盒装置虽能向外供电，但声光报警将继续进行，提醒使用者进行更换，为了保证使用安全和电池的寿命，实施时最好能带有供电开关，以免损坏电池。
具体实施时盒体1与盒体2之间还可采用其它的连接方式，即可采用面积较大的上、下面进行连接，也可采用面积较小的侧面相连的方式实现连接，即可以横向插接，也可以纵向插接，盒体的数量也可视容量的大小进行调整，可为二个或三个以上，总之对于超过运输安全锂当量的锂电池装置，可将锂电池分装在若干可以相互串联或并联的满足安全当量要求的盒体中，盒体之间通过身份标识芯片和识别芯片进行一致性检测，并进行声光报警是本发明的核心所在，也是本发明所保护的关键点。
