The invention relates to the technical field of stack water plugging judgment, and discloses an anode side water plugging judgment method, a battery, a vehicle, equipment and a storage medium, in a start-up stage, S1: when a fuel cell has a single low voltage, judging whether a difference value between an average single voltage and a lowest single voltage is greater than or equal to a first preset value; s2, when the tail exhaust valve is opened, judging whether the corresponding minimum monolithic voltage boosting amplitude is greater than or equal to a second preset value or not; s3, when the air flow is increased by a third preset value, judging whether the corresponding minimum monolithic voltage increasing amplitude is greater than or equal to a fourth preset value or not; s4, when the current density is a fifth preset value, whether the hydrogen side flow resistance is increased by a sixth preset value or not is judged; and S5, if the judgment results of S1 to S4 are positive, judging that water plugging exists on the anode side of the galvanic pile. According to the method, positioning analysis is carried out through background data, BOP related data is adjusted based on an anode water plugging occurrence mechanism and market vehicle operation experience, and judgment can be carried out by observing the change of corresponding single low-sheet voltage.

    本发明涉及电堆堵水判断技术领域,公开了一种阳极侧堵水判断方法、电池、车辆、设备及存储介质,在启机阶段:S1:当燃料电池发生单低时,判断平均单片电压与最低单片电压的差值是否大于等于第一预设值时;S2:当开启尾排阀时,判断对应最低单片电压提升幅度是否大于等于第二预设值;S3:当提升空气流量第三预设值时,判断对应最低单片电压提升幅度是否大于等于第四预设值;S4:当电密为第五预设值时,判断氢气侧流阻是否提升第六预设值;S5:若对S1‑S4的判断结果均为肯定,即判定电堆阳极侧存在堵水。通过后台数据进行定位分析,基于阳极堵水发生的机理和市场车辆运行经验,对BOP相关数据进行调整,观察对应单低片电压的变化,即可进行判断。
