摘要
为提高纯电动汽车制动时的再生制动能量回收效率,通过比较多种液压制动能量回收方案与储能方式,提出了定压源飞轮液压再生制动系统。以二次元件的排量为变量对提出系统进行原理性试验,得出系统能量回收效率与泵/马达排量的关系。对提出的再生制动系统,分别进行汽车制动工况和ECE-15工况循环仿真,仿真结果表明了能量回收效率与泵/马达排量的关系。
Aiming at solving the problems of short drive range,a constant pressure hydraulic regenerative braking system with flywheel was established.An experiment was undertaken by using displacement of pump/motor as variables,the correlation between displacement of pump/motor and efficiency of energy recovering was explored.After that braking and CEC-15 driving condition simulation based on AMEsim was investigated,correlation between displacement of pump/motor and efficiency of energy recovering was evaluated.
