The invention provides a busbar for a battery, a corresponding battery system and a vehicle. The busbar comprises a main body area and a plurality of extension parts which extend from the main body area and are spaced in the longitudinal direction of the main body area, and each extension part is provided with an end part for connecting the battery and a connecting part for connecting the end part to the main body area; each connecting part comprises a first part extending from the main body area in the extending direction of the extending part and a second part between the corresponding end part and the first part, the section of the first part in the longitudinal direction is gradually reduced in the extending direction, and the section of the second part in the longitudinal direction is gradually increased in the extending direction; and the junction part of the first part and the main body region and the junction part of the second part and the end part are smooth. With the present invention, it is possible to completely or partially avoid turbulence and consequences associated therewith while increasing the thermal resistance of the busbar to reduce heat propagation.

    本发明提供一种用于电池的汇流排以及相应的电池系统和车辆。所述汇流排包括一个主体区域和从其延伸且在其纵向方向上间隔开的多个延伸部,每个延伸部具有用于连接电池的端部以及将端部连接至主体区域的连接部,每个连接部包括在延伸部的延伸方向上从主体区域延伸的第一部分以及在相应的端部和第一部分之间的第二部分,第一部分在纵向方向上的截面沿延伸方向逐渐减小,第二部分在纵向方向上的截面沿延伸方向逐渐增大,并且第一部分与主体区域的交界部以及第二部分与端部的交界部是平滑的。利用本发明,能够在增加汇流排的热阻以减少热量传播的同时,完全或部分地避免引起湍流以及与此相关的后果。
