摘要
基于对超级电容器充放电效率和汽车行驶特性的分析,重点研究了超级电容器放电时间与其效率和汽车加速时间的匹配关系,以及根据其放电时间来确定其他参数的特殊设计规则。通过BFC 6100-EV电动大客车装车试验,表明所提出的匹配方法是可行的,超级电容器能有效地提高汽车动力性和制动能量回收,避免了动力电池组大电流放电。
Based on the analysis of ultracapacitors charge-discharge efficiency and vehicle driving character, the study focus on ultracapacitors charge-discharge time matching relation to its efficiency and vehicle acceleration time, its specific design methods decided by charge-discharge time for designing the other parameters. Through BFC 6100-EV electric bus test, results show that the proposed method is feasible and the system is valid which helps to improve dynamic performance and ability to receive braking energy effectively and prevent battery pack from discharging in high current.
