The invention provides a heat preservation method and device for a vehicle fuel cell. The method comprises the following steps: acquiring reserved travel information of a vehicle; based on the reserved travel information, the reserved travel information is used for indicating that the vehicle is to be used after a target duration, the target duration is positively correlated with the temperature difference between the environment temperature of the vehicle and the preset temperature capable of being normally output by the fuel cell of the vehicle, and the starting heating time for heating the fuel cell in advance is determined; and when the heating starting time is up, the fuel cell starts to be heated to a preset temperature, so that when the vehicle starts to travel, the fuel cell can meet a power request or a voltage request of the vehicle. According to the method, the reserved travel information of the vehicle is obtained, and after it is determined that the fuel cell can be heated to the preset temperature before the vehicle is used according to the reserved travel information, the advanced heating time is accurately determined according to the reserved travel information, so that normal output of the fuel cell can be ensured, and meanwhile, energy consumption of heat preservation of the fuel cell can be saved.
本公开提供一种车用燃料电池的保温方法及装置,方法包括:获取车辆的预约行程信息;基于预约行程信息,预约行程信息用于指示车辆将在目标时长后使用,目标时长,与车辆的环境温度与车辆的燃料电池能够正常输出的预设温度之间的温差呈正相关,确定为燃料电池提前开始加热的启动加热时间;到达启动加热时间时,开始将燃料电池加热至预设温度,以使车辆开始行程时,燃料电池能够满足车辆的功率请求或者电压请求。通过获取车辆的预约行程信息,并在通过预约行程信息确定能够在车辆使用前将燃料电池加热至预设温度后,根据预约行程信息,精准确定提前加热的时间,在确保燃料电池能够正常输出的同时,还能够节省燃料电池保温的能耗。
