The invention discloses an intelligent dynamic parallel switch assembly and a battery cluster and a battery module thereof, and the intelligent dynamic parallel switch assembly comprises a power terminal, a main channel switch, an electronic switch, a current limiting unit, a signal acquisition management unit, a management power supply input and a communication interface, the connecting end of the electronic switch is connected in series with the connecting end of the current limiting unit and is connected in parallel with the connecting end of the main channel switch; the battery module is formed by connecting a plurality of battery clusters in parallel, each battery cluster is formed by connecting a plurality of battery cells in series, thermal runaway is faced in a suppression and isolation mode, and chain reaction is eradicated; the acquisition unit judges that the working current of the main channel exceeds a set value, namely, the main channel switch is switched off, all charging and discharging currents pass through the bypass current limiting unit, the pre-charging and pre-discharging function setting of the battery is solved, and the electronic switch is switched off through the acquisition management unit under necessary conditions, so that the full-channel separation from the system is realized.

    本发明专利公开了一种智能动态并联开关组件及其电池簇和电池模块,包括动力接线端、主通道开关、电子开关、限流单元、信号采集管理单元、管理电源输入和通信接口,所述动力接线端的连接端和主通道开关的连接端串联连接,所述电子开关的连接端和限流单元的连接端串联连接,且与主通道开关的连接端并联连接;本发明专利的电池模块由多个电池簇并联而成,电池簇由多个电池电芯串联而成,通过抑制、隔离的方式面对热失控,杜绝链式反应;采集单元判断主通道的工作电流超过设定值,即断开主通道开关,所有的充放电电流均通过旁路限流单元,解决电池预充电和预放电功能设定,在必要的情况下,电子开关通过采集管理单元进行关断,实现全通道脱离系统。
