The invention relates to a start-stop control method and device for a fuel cell engine, a vehicle and a storage medium, and the method comprises the steps: obtaining the current working condition type of the vehicle and the current SOC value of a power battery when the vehicle does not need to be powered by a fuel cell; matching the minimum operation duration of the fuel cell according to the current working condition and the current SOC value; and after the fuel cell is started to operate, when the vehicle does not need to be powered by the fuel cell any more and the continuous operation duration of the fuel cell reaches the minimum operation duration, power supply of the fuel cell is stopped, and otherwise, the fuel cell is controlled to continuously supply power until the continuous operation duration reaches the minimum operation duration. The minimum operation time can be determined based on the current fuel cell attenuation rate through the working condition type and the cell SOC, so that the start-stop frequency of the fuel cell under different operation conditions is reduced, the service life of the fuel cell system is prolonged, the fuel cell system can better adapt to the operation state of the system, and the system reliability is improved. And the adaptability of the fuel cell to the current driving working condition and the control effect under the variable working condition are improved.
本申请涉及一种燃料电池发动机的启停控制方法、装置、车辆及存储介质,其中,方法包括:在车辆无需燃料电池供电时,获取车辆的当前工况类型和动力电池的当前SOC值;根据当前工况和当前SOC值匹配燃料电池的最小运行时长;在燃料电池开启运行后,当车辆不再需要燃料电池供电,且燃料电池的持续运行时长达到最小运行时长时,停止燃料电池供电,否则控制燃料电池持续供电,直至持续运行时长达到最小运行时间。本申请可基于当前燃料电池衰减速率,通过工况类型和电池SOC确定最小运行时间,从而降低不同运行条件下燃料电池启停次数,提高燃料电池系统寿命,使其能更好的适应系统的运行状态,提高燃料电池对当前行驶工况的适应性以及变化工况下的控制效果。
