针对燃料电池混合动力系统的特点对整车能量管理策略进行优化,将锂离子电池的荷电状态、整车需求功率作为输入变量,将燃料电池提供的功率、锂离子电池提供的功率和制动能量回收功率作为输出变量,提出了基于模糊控制的混合动力系统能量实时控制算法,并将新算法应用于硬件平台进行仿真与实现,同时设计出基于模糊算法的燃料电池混合动力系统整车控制器样机。算法仿真及装载该控制器的样车道路行驶试验结果表明:该控制器使整车效率达到50%以上,在提高整车燃料利用率的同时使燃料电池、锂离子电池工作在最佳状态。
The vehicle energy management strategy was optimized according to the characteristics of fuel cell hybrid vehicle system.In our study,a real-time power control algorithm for hybrid system based on fuzzy-control theory was proposed.The variables of this algorithm were set as follows： the state of charge of lithium-ion battery and the vehicle power demand were set as input variables,while the provided power of fuel cell,provided power of lithium-ion battery and the recovery power of braking energy was set as the output variables.This new method was applied to the hardware platform to obtain the simulation results,and a vehicle controller prototype was designed.The experimental results and the test results of the prototype indicate that： the new algorithm can make the vehicle power efficiency up to 50% or more,while make the fuel cell and the lithium-ion batteries work in the best condition.
