摘要
为了减少燃料电池/超级电容混合动力系统的燃料消耗,同时减少超级电容充放电次数并延长其使用寿命,提出一种基于超级电容荷电状态(SOC)滞环控制的燃料电池/超级电容混合动力系统能量管理方法。该方法根据负载及超级电容SOC的大小,使燃料电池系统尽可能地工作于最高效率区间,同时维持超级电容的SOC保持在设定的范围内。搭建燃料电池/超级电容混合动力系统测试平台,并对所提的能量管理方法进行验证,实验结果表明,该能量管理方法能有效减少燃料消耗,同时维持超级电容SOC,有利于延长超级电容使用寿命。
In order to decrease the consumption of hydrogen fuel in fuel cell/supercapacitor hybrid system,meanwhile,to reduce charge or discharge times of supercapacitor and extend its lifetime,this paper proposes an energy management method based on hysteretic control of the supercapacitor’s state of charge(SOC)about fuel cell/supercapcacitor hybrid system. The energy management method is based on the size of load and supercapacitor’s SOC,it lets fuel cell system work in highest efficiency interval and maintains the SOC of supercapacitor in suitable range. This paper set up the test platform of fuel cell/supercapacitor hybrid system,and verified the proposed energy management method,the results of experiment demonstrated that the energy management method could effectually decrease the consumption of hydrogen fuel and maintain the SOC of supercapacitor,and the proposed energy management method could help supercapacitor to extern lifetime.
