如图1-图3、图6所示，本实施例提供一种集成母排(CCS)组件1，集成母排组件1设置为电性连接多个电池模组2，该集成母排组件1主要包括支架本体100、连接件200和柔性线路板。其中，连接件200和柔性线路板集成在支架本体100上，连接件200和柔性线路板连接，柔性线路板与电池管理系统连接；连接件200连接于相邻两个电池模组2，连接件200设置为连接相邻两个电池模组2中的电芯，以使相邻两个电池模组2的电压信号能够通过连接件200传输至柔性线路板；柔性线路板的下端面上设置有温感封装(图中未示出)，温感封装贴设在电池模组2上。
基于以上设计，本实施例中的支架本体100采用工程塑料制成，成本低，减轻集成母排组件1的重量。集成母排组件1安设在多个电池模组2上，并与多个电池模组2均电连接。连接件200设置为连接相邻两个电池模组2，使得相邻两个电池模组2的电压信号能够通过连接件200传输至柔性线路板，柔性线路板将该电压信号传输至电池管理系统(Battery Management System，BMS)中，从而实现对多个电池模组2的电压信号采集。本实施例中的温感封装设置为多个，多个温感封装均设置在柔性线路板的下端面，且多个温感封装分别贴设在电池模组2的电芯上，电芯的温度信号能够被温感封装采集，并由柔性线路板传输至电池管理系统中，从而实现对多个电池模组2的温度信号采集。
与相关技术相比，本申请提供一种集成母排组件1，该集成母排组件1将连接件200、柔性线路板集成于支架本体100上，通过连接件200和温感封装实现对多个电池模组2的电压信号和温度信号的同时采集，解决了相关技术中通过单个集成母排组件1对单个电池模组2进行信号采集的问题，提高了集成母排组件1的集成度，减少零部件数量，提高装配加工效率，节约成本。连接件200的设置能够减少相关技术中导电排、底座等部件的使用，进而节约成本，节省电池模组2的内部空间，提高电池模组2的能量密度。

如图5所示，在一实施例中，第二采集件400靠近第一采集件300的端部裸露并镀金处理以形成金手指结构410，金手指结构410插接在连接器310上。连接器310上设置有第一补强板340，第一补强板340的设置能够提高金手指结构410的机械强度，使得金手指结构410与连接器310连接更加紧固，避免在使用过程中，金手指结构410出现松脱或滑落的现象。第一补强板340的材质可以为硬质工程塑料或者其他金属材质。
如图1所示，在本实施例中，第一采集件300上开设有多个防爆孔320，防爆孔320与电池模组2上的防爆阀相适配，也就是说，本实施例中的防爆孔320与防爆阀对应设置，这样能够避免当电芯发生热失控时，防爆阀打开后将第一采集件300、第二采集件400瞬间冲断的风险。
如图4所示，在一实施例中，温感封装包括热敏电阻330，热敏电阻330的一端连接于第一采集件300，另一端连接于电芯，这样使得热敏电阻330能够直接采集到电芯的温度，也就是说，通过热敏电阻330直接贴设在电芯上，进而能够确保热敏电阻330所采集到的温度信号为电芯的真实温度，提高集成母排组件1采集温度的准确性。
在一实施例中，温感封装还包括第二补强板(图中未示出)，第二补强板贴设在第一采集件300的下端面，第二补强板采用导热性能好的金属材质制成，例如金属铝或铜等材质，第二补强板能够提高温感封装的强度，确保在温感封装采集电芯温度时，热敏电阻330不会脱离第一采集件300。
如图1和图3所示，在本实施例中，连接件200包括第一连接部210和第二连接部220，第一连接部210和第二连接部220分别连接相邻两个电池模组2，第一连接部210和第二连接部220通过凹陷部230连接，凹陷部230设置在相邻两个电池模组2之间，第一连接部210、第二连接部220、以及凹陷部230一体成型。凹陷部230的设置能够解决当相邻两个电池模组2存在高度差时，连接件200难以压平的问题，进而提高集成母排组件1的加工和装配效率。
如图1和图3所示，在本实施例中，支架本体100上设置有卡接凸起110，卡接凸起110设置在相邻两个连接件200之间并卡接在相邻两个连接件200上。卡接凸起110采用绝缘材料制成，例如可以采用硬质的工程塑料制成。卡接凸起110的设置一方面能够对连接件200起到一定的固定限位作用，避免在使用 过程中，连接件200发生松动或移位的现象；另一方面，卡接凸起110能够使得相邻两个连接件200保持一定的距离，避免两个连接件200发生短路的风险。
在一实施例中，作业人员可以根据实际需求设置不同数量的卡接凸起110，本实施例不作限定。
如图6所示，本实施例还提供一种电池包，该电池包包括以上集成母排组件1和电池模组2，且集成母排组件1电性连接多个电池模组2。该电池包能够提高其自身的加工制造效率，达到节约成本的目的。
