The invention relates to the field of fuel cell vehicles, in particular to a control method for cold start of a fuel cell system, the fuel cell system and a vehicle, and the control method comprises the steps: collecting operation parameters of the fuel cell system, and calculating a target voltage feasible region of the fuel cell system; adjusting working condition parameters of the fuel cell system according to the target voltage feasible region; judging whether the actual voltage meets a target voltage feasible region or not, and if yes, continuing cold start; if not, adjusting the running state of the water pump according to the heat capacity of the fuel cell system. According to the characteristic parameters of the fuel cell system, different cold start control strategies are selected, the start efficiency is improved, special conditions possibly occurring in the system are combined, the durability and the service life of the system are considered, and the fault tolerance and control level of the system is improved.

    本发明涉及燃料电池车辆领域,具体涉及一种燃料电池系统冷启动的控制方法及燃料电池系统、车辆,所述控制方法包括:采集燃料电池系统的运行参数计算所述燃料电池系统的目标电压可行域;依据目标电压可行域调整所述燃料电池系统的工况参数;判定实际电压是否满足目标电压可行域,若是,则继续冷启动;若否,根据燃料电池系统的热容调节水泵的运行状态。本发明根据燃料电池系统的特征参数,选取不同的冷启动控制策略,提升启动效率,并结合了系统中可能出现的特殊情况,兼顾了系统的耐久性和寿命,提高了系统的容错和控制水平。
