The invention relates to the technical field of series-parallel connection switching, in particular to a dual-channel relay, a battery pack and a vehicle. The dual-channel relay comprises a first channel, a second channel, a driving mechanism and a transmission mechanism. Wherein the first path comprises a first movable pole piece and a first fixed electrode; the second path comprises a second movable pole piece and a second fixed electrode; the driving mechanism is connected with the first movable pole piece and used for driving the first movable pole piece to be in contact with or disconnected from the first fixed electrode; and the transmission mechanism is connected with the first movable pole piece and the second movable pole piece and is used for driving the second movable pole piece when the first movable pole piece moves, so that the second movable pole piece is in contact with or disconnected from the second fixed electrode. The problems that in the prior art, series-parallel connection pipe cutting is achieved through three relays, the system structure is complex, and cost is high can be solved.
本发明涉及串并联切换技术领域,具体涉及一种双通路继电器、电池包及车辆。该双通路继电器包括:第一通路、第二通路、驱动机构和传动机构。其中,第一通路包括第一动极片和第一固定电极;第二通路包括第二动极片和第二固定电极;驱动机构与第一动极片连接,用于驱动第一动极片与第一固定电极接触或者断开;传动机构连接第一动极片和第二动极片,用于在第一动极片移动时,带动第二动极片,使第二动极片与第二固定电极接触或者断开。能够解决现有技术中采用三个继电器的方式实现串并联的切管,存在系统结构复杂,成本较高的问题。
