The invention discloses a cold starting method. According to the scheme, after a power battery is powered on, the power battery supplies power to a heating device so that the temperature of a fuel cell can be increased to the preset temperature, and after fuel is increased to the preset temperature, the cold start method is started so that traction of a vehicle can be achieved. Therefore, the power battery and the fuel battery are combined, the characteristic that the power battery can still output low power even though the performance of the power battery is poor in the low-temperature environment is utilized, and in the early stage of vehicle starting, the power battery is used for supplying power to the load, and meanwhile the low power is output for supplying power to the heating device of the fuel battery so that the temperature of the fuel battery can be increased; therefore, the fuel cell can be started in a low-temperature environment, and an additional power supply module does not need to be arranged, so that normal starting of the vehicle is ensured. The invention further discloses a cold starting system and a vehicle. The cold starting system and the vehicle have the same beneficial effects as the cold starting method.

    本发明公开了一种冷启动方法,该方案中,动力电池上电后先为加热装置供电以使燃料电池的温度升高至预设温度,在燃料升高至预设温度之后再启动以实现对车辆的牵引。可见,本申请中将动力电池与燃料电池相结合,利用动力电池在低温的环境性虽然性能较差,但仍然能输出小功率的特性,在车辆启动前期,使用动力电池为负载供电的同时,还输出小功率为燃料电池的加热装置供电以提高燃料电池的温度,以使燃料电池在低温的环境中也可以实现启动,且不需要设置额外的电源模块,从而保证了车辆的正常启动。本发明还公开了一种冷启动系统及车辆,与上述冷启动方法具有相同的有益效果。
