The invention relates to a power battery system, in particular to a connecting piece, a battery pack and a vehicle, the connecting piece is used for electrically connecting two battery cell monomers, and comprises a first connecting part and a second connecting part which are detachably connected with pole columns of the battery cell monomers; the first connecting part is provided with a first interface for pluggable connection of the first temperature acquisition terminal, and the second connecting part is provided with a second interface for pluggable connection of the second temperature acquisition terminal; and the first connecting part or the second connecting part is provided with a third interface for pluggable connection of the voltage acquisition terminal. The battery pack comprises a box body and a plurality of battery cell monomers which are detachably connected in the box body, and the plurality of battery cell monomers are electrically connected through the connecting piece. The defects that the whole battery pack needs to be replaced and the assembly time is long when the battery cells of the existing CTP battery pack are maintained are overcome, the assembly process is simplified, poor welding of the whole pack of power distribution cells is avoided, the production cost of the whole pack is reduced, and the maintenance cost of the whole pack is reduced.

    本发明涉及动力电池系统,具体涉及一种连接巴片、电池包及车辆,该连接巴片用于两个电芯单体之间的电连接,包括与电芯单体的极柱可拆卸连接的第一连接部和第二连接部;所述第一连接部上设有供第一温度采集端子可插拔连接的第一接口,所述第二连接部上设有供第二温度采集端子可插拔连接的第二接口;第一连接部或第二连接部上设有供电压采集端子可插拔连接的第三接口。该电池包包括箱体以及可拆卸连接于箱体内的多个电芯单体,多个电芯单体之间通过上述的连接巴片进行电连接。其解决了现有CTP电池包的电芯维修时需更换整个电池包、装配时间长的缺点,简化了装配工艺,整包装配电芯连接无焊接不良产生,降低整包生产成本且降低了整包的维修成本。
