A vehicle having a relay adhesion diagnosis function and a relay adhesion diagnosis method, the vehicle being configured to be connectable to a charger providing a charging voltage, and the vehicle including: a fuel cell configured to provide a stack voltage; a multiplexer configured to increase a level of the charging voltage or the stack voltage and output the charging voltage or the stack voltage having the increased level as a boosted voltage; a charging relay disposed between the charger and the multiplexer; and a battery configured to store electrical energy of the boosted voltage. The multiplexer includes: a booster connected between the charging relay and the battery and configured to generate the boosted voltage; and a converter controller configured to diagnose whether the charging relay is adhered using the sensing results of the input terminal voltage and the output terminal voltage of the charging relay.

    一种具有继电器粘连诊断功能的车辆和继电器粘连诊断方法,该车辆被配置为可连接至提供充电电压的充电器,并且该车辆包括:燃料电池,该燃料电池被配置为提供堆电压;多路转换器,该多路转换器被配置为提高充电电压或堆电压的水平并且将具有提高的水平的充电电压或堆电压作为提升后的电压输出;充电继电器,布置在充电器和多路转换器之间;以及电池,该电池被配置为存储提升后的电压的电能。多路转换器包括:升压器,连接在充电继电器与电池之间并且被配置为生成该提升后的电压;以及转换器控制器,被配置为使用充电继电器的输入端电压和输出端电压的感测结果来诊断充电继电器是否粘连。
