The invention relates to the technical field of vehicles, in particular to a low-temperature starting method and device of a fuel cell vehicle, the vehicle, a medium and a product, and the method comprises the steps that the current environment temperature when the fuel cell vehicle is started and the current charge state of a power battery are obtained; according to the current environment temperature, a charge state limit value of power battery starting is determined, and the current environment temperature and the charge state limit value are in an inverse proportion relation; and if the current charge state is greater than the charge state limit value, starting the fuel cell vehicle by using the power cell, otherwise, starting the fuel cell vehicle by using the fuel cell. Therefore, the problems of fuel cell vehicle failure and the like caused by excessive power consumption of the power battery in the starting period of the fuel cell vehicle in a low-temperature environment in the related technology are solved.

    本申请涉及车辆技术领域,特别涉及一种燃料电池车辆的低温启动方法、装置、车辆、介质及产品,其中,方法包括:获取燃料电池车辆启动时的当前环境温度和动力电池的当前荷电状态;根据当前环境温度确定动力电池启动的荷电状态限值,其中,当前环境温度与荷电状态限值呈反比例关系;若当前荷电状态大于荷电状态限值,则利用动力电池启动燃料电池车辆,否则利用燃料电池启动燃料电池车辆。由此,解决了相关技术中在低温环境下,燃料电池车辆启动时段内,动力电池过度耗电造成燃料电池车辆故障等问题。
