The invention provides a cold starting method and device of a fuel cell vehicle and the fuel cell vehicle. The method comprises the steps that under the condition that a starting signal for starting a fuel cell is received and a power cell is allowed to be charged, whether the current current of the fuel cell reaches the minimum required current or not is determined based on the allowable charging current of the power cell and the load current of the fuel cell vehicle; under the condition that the current current of the fuel cell does not reach the minimum demand current, determining a difference value between the minimum demand current and the current current of the fuel cell to obtain a target demand current; and the resistor is controlled to work according to the target demand current, so that the current current of the fuel cell can reach the minimum demand current, the fuel cell is subjected to cold start, and the problem that in the prior art, the low-temperature cold start speed of a fuel cell vehicle is low is solved.

    本申请提供了一种燃料电池车辆的冷启动方法、冷启动装置与燃料电池车辆。该方法包括:在接收到对燃料电池进行启动的启动信号且容许对动力电池进行充电的情况下,基于动力电池的容许充电电流以及燃料电池车辆的负载电流,确定燃料电池的当前电流是否到达最小需求电流;在燃料电池的当前电流未达到最小需求电流的情况下,确定最小需求电流与燃料电池的当前电流的差值,得到目标需求电流;控制电阻器按照目标需求电流进行工作,以使得燃料电池的当前电流可达到最小需求电流,从而使得燃料电池进行冷启动,解决了现有技术中燃料电池车辆的低温冷启动速度较慢的问题。
