Description

一种无并联大容量锂离子电池模块
技术领域
本发明属于化学电源技术领域，尤其涉及一种无并联大容量锂离子电池模块。
背景技术
随着能源危机和环境污染问题的日益突出，开发可再生、高比能量、环境友好型的可替代能源就成为当务之急。
锂离子电池具有高比能量,转换效率高,环境友好,循环寿命长,自放电小等优点,是一种理想的绿色能源,具有广阔的应用空间。但目前锂离子电池的应用主要集中于通讯和IT等电子行业,主要是容量小于5Ah的小型电池。
随着城市环境污染的加剧以及风、光能利用的普及，对大型动力源和储能系统的需求急剧增加,如各种电动摩托、电动汽车、电动大巴、电动公交车、UPS、风能发电以及太阳能发电储能电池堆等。理论上，小型电池通过串(并)联、混联方式可以集成大型动力源，以满足大型电气设备的用电需求。但在实际应用中,并联电池在充放电末端将出现严重的电流不平衡现象，对单体电池一致要求很高,电池组中任何一只出现问题,将会影响到整组电池的性能发挥。同时,锂离子电池的应用必需要加上电池管理系统,而当今的电池管理技术也只能对串联进行管理,并无电池并联管理的电子技术,也缺少并联方式的电池性能评估方法和评价指标的相关研究。因此，从技术和产业化角度来看,小型电池并联的方案难以满足大容量电池的需求。
发明内容

技术方案：一种无并联大容量锂离子电池模块，包括无并联大容量锂离子电池组和电池管理单元，
所述无并联大容量锂离子电池组是由至少两个50～2000AH单体大容量聚合物锂离子电池串联而成；
所述电池管理单元包括主控模块、数据采集模块、均衡器和检测部件，所述检测部件包括至少一个电流传感器、至少两个电压传感器和至少两个温度传感器，
所述电流传感器与所述单体大容量聚合物锂离子电池串联，
每个单体大容量聚合物锂离子电池均与一个电压传感器并联，
每个单体大容量聚合物锂离子电池的正极极耳均与一个温度传感器相连，
所述电流传感器、所述电压传感器、所述温度传感器与所述数据采集模块相连；
所述数据采集模块与所述主控模块相连；
所述主控模块与所述均衡器相连；
所述均衡器分别与所有的单体大容量聚合物锂离子电池相连。
作为本发明中一种无并联大容量锂离子电池模块的一种优选方案：所述单体大容量聚合物锂离子电池的顶部设有正极极耳和负极极耳，所述单体大容量聚合物锂离子电池的外侧设有铝塑复合包装膜，在所述铝塑复合包装膜的外侧设有导热板。
进一步地，所述导热板为铝板、铝合金板、石墨板和碳板中的一种。
有益效果：本发明公开的一种无并联大容量锂离子电池模块具有以下有益效果：
1、每只单体大容量聚合物锂离子电池在工作时的电压和电流均可实时监控；
2、由于单体大容量聚合物锂离子电池的内阻小、单体大容量聚合物锂离子电池外表面的导热板可有效传导电池组内部的热量，因此电池组的工作温度较低。
