The invention discloses a fuel cell vehicle low-temperature starting method which is applied to a dual-fuel system, the dual-fuel system comprises a first fuel system and a second fuel system, and the method comprises the steps that when the vehicle is in a low-temperature environment, the current working condition of the vehicle is obtained; under the condition that the current working condition is the starting working condition, a power battery supplies power to the first fuel system so as to start the first fuel system; and the started first fuel system is controlled to heat the second fuel system at the first target output power. According to the scheme, the power battery supplies power to the first fuel system preferentially, the first fuel system heats the second fuel system after being started, under the condition, the power battery only needs to supply power to one fuel system, and the discharge power requirement of the power battery is reduced. Meanwhile, the second fuel system is heated after the first fuel system is started, the electric quantity generated after the first fuel system is started is effectively utilized, and the utilization rate of the electric quantity is increased.
本申请公开了一种燃料电池车辆低温启动方法,应用于双燃料系统,所述双燃料系统包括第一燃料系统和第二燃料系统,包括:在车辆处于低温环境下,获取车辆当前工况;在所述当前工况为启动工况的情况下,由动力电池为所述第一燃料系统供电,以启动所述第一燃料系统;控制启动后的所述第一燃料系统以第一目标输出功率为所述第二燃料系统进行加热。本方案通过动力电池优先对第一燃料系统供电,第一燃料系统启动后对第二燃料系统进行加热,在此种情况下,动力电池仅需给一个燃料系统供电,减小了动力电池的放电功率需求。同时,第一燃料系统启动后给第二燃料系统加热,有效利用了第一燃料系统在启动后产生的电量,提高了电量的利用率。
