针对纯电动汽车能量利用率低的问题,提出对电动汽车进行制动能量回收,通过比较多种液压制动能量回收方案与储能方式,认为定压源飞轮液压再生制动系统较合理,且对该系统分别进行汽车联合制动工况和城市循环工况仿真,分析系统制动能量回收利用率和节能效果,仿真结果显示,泵/马达排量在一定范围内,制动能量回收效率与排量大小呈正相关,续驶里程能提高24%左右。
針對純電動汽車能量利用率低的問題,提齣對電動汽車進行製動能量迴收,通過比較多種液壓製動能量迴收方案與儲能方式,認為定壓源飛輪液壓再生製動繫統較閤理,且對該繫統分彆進行汽車聯閤製動工況和城市循環工況倣真,分析繫統製動能量迴收利用率和節能效果,倣真結果顯示,泵/馬達排量在一定範圍內,製動能量迴收效率與排量大小呈正相關,續駛裏程能提高24%左右。

In order to improve efficiency of recovering braking energy in electrical vehicle, a constant pressure hydraulic regenerative braking system with flywheel has been designed after comparing several hydraulic regenerative braking schemes. Then the joint braking and CEC-15 driving condition simulation based are processed. The results of simulation indicate positive correlation between displacement of pump/motor and efficiency of energy recovering under a certain value of displacement and driving range of electrical has been prolonged by 24%.
