The invention discloses a voltage inspection device and method for a fuel cell stack and a vehicle. Wherein the fuel cell stack comprises a plurality of single cells which are sequentially connected in series and stacked, the voltage inspection device comprises a plurality of first plug connectors, a plurality of second plug connectors and a voltage inspection module, the plurality of first plug connectors are connected with the plurality of single cells in a one-to-one correspondence manner, and each first plug connector is arranged at an anode inlet of the corresponding single cell; and the plurality of second plug connectors are connected with the plurality of single batteries in a one-to-one correspondence manner, each second plug connector is arranged at the anode outlet of the corresponding single battery, and the voltage inspection module is electrically connected with the plurality of first plug connectors and the plurality of second plug connectors so as to respectively obtain the first voltage and the second voltage of each single battery. Therefore, the voltage inspection module can acquire the first voltage and the second voltage at the same time, the synchronism of voltage signal acquisition of each single cell is ensured, and convenience is provided for subsequent fault diagnosis of a fuel cell stack.

    本发明公开了一种燃料电池堆的电压巡检装置、电压巡检方法及车辆。其中,燃料电池堆包括多个依次串联层叠的单片电池,电压巡检装置包括:多个第一插接件、多个第二插接件和电压巡检模块,多个第一插接件与多个单片电池一一对应连接,且每个第一插接件设于相应单片电池的阳极入口处,多个第二插接件与多个单片电池一一对应连接,且每个第二插接件设于相应单片电池的阳极出口处,电压巡检模块与多个第一插接件、多个第二插接件均电连接,以分别获取每个单片电池的第一电压和第二电压。由此,该电压巡检模块能够同时获取第一电压和第二电压,保证了每个单片电池电压信号采集的同步性,为燃料电池堆的后续故障诊断提供了便利。
