The invention discloses a hydrogen fuel automobile hydrogen system starting control method, which comprises the following steps: W1, when an automobile runs, judging whether to start a hydrogen fuel system and required power according to the current battery health condition, battery discharge rate, battery temperature and battery electric quantity change within a period of time; w2, the needed power is compared with the optimal power of the hydrogen fuel system in the current vehicle state, and if the needed power is large, the hydrogen fuel system is started according to the needed power; w3, if the required power is small, calculating the residual power, and comparing the current rechargeable power of the battery; w4, if the rechargeable power of the battery is large, the hydrogen fuel system is started according to the optimal starting power; otherwise, the hydrogen fuel system is started according to the required power; w5, when the total electric quantity of the battery rises for an interval or the starting time reaches a time period, whether the hydrogen fuel system is started or not is judged again, and the step W1 is returned; and W6, when the condition of closing the hydrogen fuel system is met, recording the data and ending.

    本发明公开了一种氢燃料汽车氢系统启动控制方法,W1:车辆行驶时,根据当前电池健康状况,电池放电倍率,电池温度,在一段时间内的电池电量变化,判断是否开启氢燃料系统及所需功率;W2:将所需功率与当前车辆状态下氢燃料系统的最优功率进行对比,如所需功率较大时,按所需功率来启动氢燃料系统;W3:如所需功率较小时,计算剩余功率,再对比当前电池的可充电功率;W4:若电池的可充电功率较大时,氢燃料系统按最优启动功率启动;反之,氢燃料系统按所需功率启动;W5:电池总电量上升一个区间或者启动时间达到一个时间段时,再进行重新判断是否开启氢燃料系统,返回W1;W6:达到关闭氢燃料系统条件,记录本次数据并结束。
