The invention provides a vehicle-mounted hydrogen storage system fault diagnosis system and method, a vehicle-mounted terminal and a vehicle. The method comprises the steps that the vehicle-mounted target hydrogenation quality at the current moment, the target filling pressure at the current moment, the vehicle-mounted actual hydrogenation quality at the current moment and the filling pressure at the current moment are obtained; if the hydrogen mass change value at the current moment is larger than the preset mass threshold value, whether the vehicle-mounted hydrogen storage system breaks down or not is judged according to the pressure change value at the current moment, and fault warning is conducted under the condition that the fault occurs, so that once the hydrogen storage system breaks down, hydrogen leakage may be caused, and the hydrogen leakage is avoided in the hydrogenation process of the fuel cell. According to the method, fault identification is carried out on the hydrogen storage system, and fault reasons are checked based on different parameter changes, so that maintenance personnel can judge fault types and positions more accurately and take corresponding repair measures, the safety of vehicles and a hydrogenation machine in the hydrogenation process is ensured, potential safety hazards are avoided, and the safety of the vehicles and passengers is ensured.
本申请提出的一种车载储氢系统故障诊断系统、方法、车载终端及车辆,该方法包括:获取当前时刻的车载目标加氢质量、当前时刻的目标加注压力、当前时刻的车载实际加氢质量和当前时刻的加注压力;若当前时刻的氢气质量变化值大于预设质量阈值,则根据当前时刻的压力变化值判定车载储氢系统是否发生故障,并在发生故障的情况下进行故障警示,由于储氢系统一旦发生故障,可能会导致氢气泄漏,通过在燃料电池加氢过程中,对储氢系统进行故障识别,并基于不同的参数变化排查故障原因,从而便于维修人员更准确地判断故障类型和位置,并采取相应的修复措施,保证加氢过程车辆及加氢机的安全,避免潜在的安全隐患,确保车辆和乘客的安全。
