Embodiment Construction
[0026] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.
[0027] figure 1 It is a flow chart of a fuel cell system fault handling method according to an exemplary embodiment of the present disclosure. Such as figure 1 As shown, the method includes step S101 to step S103.
[0028] In step S101, the operating parameters of the fuel cell system and the current driving state of the vehicle are acquired.
[0029] The operating parameters of the fuel cell system refer to the data obtained by various sensors during the operation of the fuel cell system and used to monitor the operating status of the fuel cell, for example, the temperature of the fuel cell stack, the output voltage of the fuel cell system, the output cur...

The invention relates to a fuel cell system fault processing method and device. The method comprises the following steps: acquiring operation parameters of the fuel cell system and a current driving state of a vehicle; if the fuel cell system breaks down, the cause of the fault is determined according to the operation parameters, the fault and a preset fuzzy control rule; according to the reason of the fault and the current driving state, judging whether the fault is a fault capable of being processed in a delayed manner or not; and if the fault is judged to be the fault capable of being processed in a delayed manner, carrying out delayed processing on the fault. Therefore, after the fuel cell system fails, a worker does not need to restart the vehicle at a maintenance site and detect various operating parameters one by one to screen fault causes, manpower is saved, and the real-time performance is good. And moreover, accidents caused by sudden shutdown of the fuel cell system due to faults in the running process of the vehicle can be avoided, and the driving safety is improved.
Description
technical field [0001] The present disclosure relates to the field of new energy vehicles, and in particular, to a fuel cell system fault handling method and device. Background technique [0002] Today, fuel cell vehicles, as a type of new energy vehicles, are gradually entering people's lives. During the operation of the fuel cell system, all key components may be damaged for some reason, resulting in the failure of the fuel cell system to operate normally, resulting in a decrease in vehicle performance. In related technologies, when the fuel cell system fails, the shutdown of the fuel cell system is automatically controlled. Contents of the invention [0003] The purpose of the present disclosure is to provide a method and device for troubleshooting a fuel cell system, so as to improve the stability of the fuel cell system during use and the safety of the vehicle. [0004] In order to achieve the above object, the present disclosure provides a fuel cell system fault ha...
