The invention belongs to the technical field of new energy, and particularly relates to a fuel cell automobile and an all-weather monitoring system of a hydrogen system of the fuel cell automobile. In order to solve the problem that power consumption of a power battery is high due to the fact that the power battery supplies power to a hydrogen system in a full time domain mode when a whole vehicle is powered off in the prior art, so that the low-voltage electrical system is completely electrified, two different power supply lines are used for supplying power to a monitoring unit; and an anti-reverse diode is serially arranged on a line for supplying power to the monitoring unit by the whole vehicle low-voltage power supply module, so that the whole vehicle low-voltage power supply module can only supply power to the monitoring unit unidirectionally, and the whole vehicle low-voltage electrical system is prevented from being electrified when the vehicle power battery power supply module supplies power. The power consumption when the power battery power supply module serves as a power supply is reduced, the long-term parking safety monitoring period is prolonged, and the safety of the system under the vehicle parking power-off monitoring state is guaranteed.

    本发明属于新能源技术领域,具体涉及一种燃料电池汽车及其氢系统的全天候监控系统。为解决现有技术中在整车断电时通过动力电池全时域为氢系统供电,以使低压电气系统全部带电,导致动力电池耗电量高的问题,本发明通过两路不同的供电线路对监控单元进行供电,以及在整车低压供电模块向监控单元供电的线路上串设防反二极管,以使整车低压供电模块只能单向为监控单元供电,防止在车辆动力电池供电模块进行供电时,使整车低压电气系统全部带电,减少在动力电池供电模块作为供电电源时的耗电量,提升长期停放安全监控周期,保证车辆停车断电监控状态下系统的安全性。
