The invention relates to the technical field of vehicles, in particular to a hydrogen leakage prevention method and device, a vehicle and a storage medium. The method comprises the steps that the hydrogen pile state of a hydrogen system is obtained, a first pressure relay is used for collecting first pressure, and a second pressure relay is used for collecting second pressure; if it is judged that the hydrogen system meets the preset pressure reduction condition according to the hydrogen pile state, the first pressure and the second pressure, the current state of a hydrogen concentration sensor of the hydrogen system is obtained; and if the current state is an alarm state, an electromagnetic valve closing instruction is generated according to the first pressure and the second pressure, and the first electromagnetic valve and/or the second electromagnetic valve are/is closed according to the electromagnetic valve closing instruction, so that hydrogen leakage is prevented. Therefore, opening and closing of the electromagnetic valve are controlled through signals of the pressure relay, the problems of potential safety hazards, influence on work and the like caused by hydrogen leakage due to faults of the safety valve or the emptying valve are avoided, and driving safety is guaranteed while hydrogen leakage is prevented.

    本申请涉及车辆技术领域,特别涉及一种氢气防泄露方法、装置、车辆及存储介质,其中,方法包括:获取氢系统的氢堆状态,并利用第一压力继电器采集第一压力,且利用第二压力继电器采集第二压力;若根据氢堆状态、第一压力和第二压力判定氢系统满足预设压力下降条件,则获取氢系统的氢浓度传感器的当前状态;若当前状态为报警状态,则根据第一压力和第二压力生成电磁阀关闭指令,并根据电磁阀关闭指令对第一电磁阀和/或第二电磁阀进行关闭,以防止氢气泄露。由此,通过压力继电器的信号控制电磁阀的开和关,避免了因安全阀或者放空阀故障导致氢气泄露带来的安全隐患、影响工作等问题,在防止氢气泄露的同时,保障了行车安全。
