Simulation Analysis of Multi-condition Dynamic Characteristics of the Vehicle-mounted Super-capacitor Pack

车载使用工况下,超级电容器性能参数的变化不同于常规室温下的变化规律。为了研究超级电容器性能参数在电动汽车实际应用过程中的变化规律,首先设计了不同的实验方法模拟车载超级电容使用的不同情形,获取了相应的结果。进一步,基于实验测量的结果得出超级电容器在不同行驶工况下的性能参数值。据此,仿真分析了车载超级电容器组性能参数的变化对其自身动态特性的影响。

In the case of vehicle operation,the performance parameters′change of super-capacitor is different from that in conventional room temperature.In order to study the variation of the super capacitor performance parameters in the actual application process of electric vehicles,different experimental methods were designed to simulate different situations using super capacitor car to get the corresponding results firstly.Furthermore,based on the experimental results,the performance parameters of super-capacitor under different driving cycles were concluded.At last,the influence on the dynamic characteristics by the changing of performance parameters of the vehicle super-capacitor group was analyzed with simulation.
