The invention discloses a battery pack cut-off unit, a battery pack and a vehicle. The battery pack cut-off unit comprises a sampled electronic element, a high-voltage sampling board and a low-voltage sampling board. The electronic component comprises a high-voltage sampling point and/or a low-voltage sampling point And the high-voltage sampling plate is provided with a high-voltage copper bar electrically connected with the high-voltage sampling points so as to sample corresponding electronic elements. And the low-voltage sampling plate is provided with a low-voltage copper bar connected with the low-voltage sampling point so as to sample the corresponding electronic element. And the high-voltage sampling plate and the low-voltage sampling plate are arranged at intervals in the vertical direction. Therefore, the high-voltage sampling plate replaces a high-voltage wiring harness, the low-voltage sampling plate replaces a low-voltage wiring harness, the battery pack cutting unit does not need to correspondingly connect the wiring harnesses with a high-voltage sampling point and a low-voltage sampling point, the problem that the wiring harnesses are disordered does not exist, and moreover, the high-voltage sampling plate and the low-voltage sampling plate are arranged at an interval in the vertical direction, so that the wiring harnesses are not damaged. Complete separation of high voltage and low voltage is achieved, electromagnetic interference is reduced or avoided, and the reliability of the battery pack cut-off unit is higher.

    本申请公开一种电池包切断单元、电池包和车辆。所述电池包切断单元包括被采样的电子元件、高压采样板和低压采样板。电子元件包括高压采样点和/或低压采样点。高压采样板设置有与高压采样点电连接的高压铜排,以能对相应的电子元件采样。低压采样板设置有与低压采样点连接的低压铜排,以能对相应的电子元件采样。高压采样板和低压采样板在竖直方向间隔设置。由此,通过高压采样板替代高压线束,低压采样板替代换低压线束,电池包切断单元不再需要线束相应的与高压采样点和低压采样点连接,不存在线束杂乱无章的问题,再者,高压采样板和低压采样板在竖直方向间隔设置,实现了高低压完全分离,降低或者避免电磁干扰,电池包切断单元可靠性更高。
