为了解决多能源系统燃料电池寿命周期短、燃料效率低的问题，开发了燃料电池混合动力汽车。本研究的目的是利用小波变换对燃料电池混合动力汽车的多能源系统进行仿真、评价和调节。开始，根据仿真环境构建燃料电池的混合模型和燃料电池的总体动态模型以及DC/DC转换器模型。其次，成功地捕获了混合动力汽车系统的功率信息，并利用小波变换对采集到的功率信号进行了处理。燃料电池功率控制和复合电源的功率分配模块独立地输入混合动力系统的低频和高频功率需求。PI控制用于调节混合动力系统中存储装置的功率，以及输出燃料电池和超级电容器的功率设置。仿真结果表明，基于小波变换的混合动力汽车多能源系统的动力电池波动范围明显小于其他方法，整个过程运行在低功率点。实验结果表明，在这项研究中给出的策略可以成功地延长燃料电池的寿命，同时也降低了车辆系统的整体燃油效率。
In order to address the issue of multi-energy system fuel cells having a short life cycle and low fuel efficiency, a Fuel Cell Hybrid Vehicle was developed. The goal of this research is to use wavelet transformation to simulate, evaluate, and regulate the multi-energy system of a fuel cell hybrid car. To begin, a hybrid model of the fuel cell and an overall dynamic model of the fuel cell, as well as a DC/DC converter model, are constructed in accordance with the simulation environment. Second, the hybrid vehicle system's power information is successfully captured, and the power signal acquired is processed using the wavelet transform. The fuel cell power control and the composite power supply's power allocation module are independently input into the hybrid system's low frequency and high frequency power requirements. PI control is used to regulate the power of the storage device in the hybrid power system, as well as the power settings of the output fuel cell and supercapacitor. The simulation results show that the power battery fluctuation range of the hybrid vehicle multi-energy system based on the wavelet transform proposed in this paper is significantly smaller than that of other methods, and the entire process operates at low power points. The results of the experiments suggest that the strategies given in this study can successfully extend the life of fuel cells while also lowering the overall fuel efficiency of the vehicle system.
