The invention discloses a fuel cell system control strategy and an electric vehicle. The control strategy comprises the steps that if the one-time detection out-of-tolerance of the air inlet pressure of the fuel cell system reaches a first preset value, the speed of the automobile is larger than zero, and the SOC value of the power battery is smaller than a second preset value, and/or if the one-time detection out-of-tolerance of the air inlet pressure of the fuel cell system reaches the first preset value, the speed of the automobile is equal to zero; if the automobile detects that the user gets off and cleans the automobile, the secondary detection out-of-tolerance of the air inlet pressure of the fuel cell system reaches a first preset value, the SOC value of the power battery is smaller than a second preset value, and/or if the primary detection out-of-tolerance of the air inlet pressure of the fuel cell system reaches the first preset value, the speed of the automobile is equal to zero; and if the automobile does not detect that the user gets off the automobile for cleaning confirmation and the SOC value of the power battery is smaller than a second preset value, controlling the electromagnetic butterfly valve of the resonant cavity to be opened. According to the embodiment of the invention, the air inlet of the fuel cell system can be subjected to blockage diagnosis, and the risk of vehicle breakdown is reduced.
本发明公开了一种燃料电池系统控制策略及电动汽车。该控制策略包括:若燃料电池系统进气口压力一次检测超差达到第一预设数值,汽车的车速大于零,动力电池的SOC值小于第二预设数值和/或若燃料电池系统进气口压力一次检测超差达到第一预设数值,汽车的车速等于零,汽车检测到用户下车清理确认,燃料电池系统进气口压力二次检测超差达到第一预设数值,动力电池的SOC值小于第二预设数值和/或若燃料电池系统进气口压力一次检测超差达到第一预设数值,汽车的车速等于零,汽车未检测到用户下车清理确认,动力电池SOC值小于第二预设数值,则控制谐振腔的电磁蝶阀打开。本发明实施例能对燃料电池系统进气口进行堵塞诊断,降低车辆抛锚的风险。
