The invention relates to a switch adhesion detection system, method and device, a vehicle and a medium. The system comprises a power supply circuit and a detection unit. The power supply circuit comprises at least two power supply branches, each power supply branch comprises a battery module and an in-branch switch which are connected in series, an inter-branch switch is arranged between at least two adjacent power supply branches, and the in-branch switch and the inter-branch switch are used for controlling the working mode of the power supply circuit; the first end of the detection unit is connected with the first end of each power supply branch, the second end of the detection unit is connected with the second end of each power supply branch, and the detection unit is used for detecting whether a target switch corresponding to a working mode is adhered or not in any working mode of the power supply circuit; the target switch is any switch in a closed state in the working mode. Therefore, the plurality of battery modules share the same reference point, so that the problem that a plurality of reference points need to be isolated from one another does not exist.

    本公开涉及一种开关粘连检测系统、方法、装置、车辆及介质。系统包括电源电路和检测单元;电源电路包括至少两个电源支路,且每一电源支路包括串联连接的电池模块和支路内开关,至少相邻两个电源支路之间设置有支路间开关,其中,支路内开关和支路间开关用于控制电源电路的工作模式;检测单元的第一端分别与每一电源支路的第一端相连,检测单元的第二端分别与每一电源支路的第二端相连,用于在电源电路的任一工作模式下检测与该工作模式对应的目标开关是否粘连,目标开关为在该工作模式下处于闭合状态的任一开关。如此,多个电池模块共用同一个基准点,因此,不存在多个基准点需要互相隔离的问题。
