摘要
通过优化超级电容充电轨迹来提升充电效率是近年来超级电容在船舶领域应用研究中的一个研究热点。在分析超级电容等效参数变化规律的基础上,提出一种适合进行超级电容充电轨迹调控的物理-行为混合模型。该模型通过准在线参数辨识测试获取电容等效电容和电阻参数,能充分反映超级电容的容压特性、阻流特性和老化等对等效参数的影响。仿真和试验结果表明:该模型具有精度高和参数辨识简便等优点,可为超级电容在船舶等领域的应用提供支撑。
As a kind of energy storage element,supercapacitor has the advantages of high power density and wide operating temperature range,etc.With the proposal of energy conservation and emission reduction targets such as dual carbon,supercapacitors are increasingly used in ships such as ferries.It is a research hotspot in the field of supercapacitor ships in recent years to improve the charging efficiency by adjusting the charging trajectory of supercapacitors.A hybrid physical-behavioral model for supercapacitor charging trajectory regulation is proposed based on the analysis of the variation law of supercapacitor equivalent parameters.The model obtains the equivalent capacitance and resistance parameters of the capacitor by quasi-online parameter identification test,which can fully reflect the capacitance-voltage characteristics,current-resistance characteristics and the influence of aging on the equivalent parameters of the supercapacitor.The simulation and experimental results show that the model has the advantages of high accuracy and easy parameter identification,which can provide support for supercapacitor charging performance improvement.
