The invention discloses a preheating control method and device for a plug-in fuel cell vehicle. The method comprises the steps that the travel time and a preheating demand are set through an APP; whether the automobile needs to be charged is detected; after the charging is completed or when the charging is not needed, the TBOX calculates the advanced preheating time; the TBOX awakening time is set, and the vehicle enters a sleep state after setting is completed; after the time is up, the TBOX is awakened, the VCU is awakened after the TBOX is awakened, the BMS\ FCU\ MCU\ DCDC&OBC is awakened by the VCU, and state monitoring is carried out; the OBC is started after completion of determination, electric quantity is provided for work of the PTC, and a power battery and a fuel cell system arepreheated; after preheating is completed, the vehicle enters a sleep state, and the vehicle is started by a user. The defect that an existing fuel cell vehicle cannot be started at a low temperature or waits for a long time to be started is overcome.

    本发明公开一种插电式燃料电池汽车预热控制方法及装置,所述方法包括:通过APP设定出行时间及预热需求;检测汽车是否需要充电;充电完成后或无需充电时,TBOX计算提前预热时间;设定TBOX唤醒时间,完成设定后车辆进入休眠状态;时间达到后TBOX唤醒,TBOX完成唤醒后唤醒VCU,VCU唤醒BMS\FCU\MCU\DCDC&OBC,进行状态监测;确定完成后OBC启动,为PTC工作提供电量,为动力电池与燃料电池系统进行预热;预热完成后,车辆进入休眠状态,待用户启动车辆,本发明解决了现有燃料电池汽车在低温下无法启动或等待启动时间长的缺点。
