The invention relates to the technical field of fuel cells, in particular to a self-adaptive power adjusting method and device of a fuel cell system, a vehicle and a medium, and the method comprises the following steps: acquiring the current hydrogen in-pile pressure of the fuel cell system; and if the current hydrogen in-pile pressure is greater than a first preset pressure and is less than a second preset pressure, adjusting the fuel cell stack to output target power according to a preset energy management strategy, otherwise, determining a current pressure interval of the current hydrogen in-pile pressure, and matching an optimal power adjustment strategy according to the current pressure interval, and executing corresponding actions according to the optimal power regulation strategy. Therefore, the problems that the fuel cell is stopped emergently, the fuel cell system cannot be started normally and the like due to low or high accidental in-pile pressure caused by non-leakage in the running process of the vehicle are solved, the fault rate of the fuel cell system is reduced, the potential safety hazard of the vehicle is reduced, and the endurance mileage of the whole vehicle is increased.
本申请涉及燃料电池技术领域,特别涉及一种燃料电池系统的自适应功率调节方法、装置、车辆及介质,其中,方法包括:获取燃料电池系统的当前氢入堆压力;若当前氢入堆压力大于第一预设压力且当前氢入堆压力小于第二预设压力,则根据预设的能量管理策略调节燃料电池电堆输出目标功率,否则确定当前氢入堆压力的当前所处压力区间,并根据当前所处压力区间匹配最优功率调节策略,根据最优功率调节策略执行相应的动作。由此,解决了由于车辆行驶过程中的非泄露原因造成偶然性入堆压力低或高,从而导致燃料电池紧急停机以及燃料电池系统无法正常启动等问题,减少燃料电池系统的故障率,降低车辆安全隐患,增加整车续航里程。
