【摘要】 针对电动汽车存在一次充电续驶里程短等问题,目前常采用电容器作为辅助能源来均衡负载并迅速吸收能量回馈制动能量。与超级电容器相比,薄膜电容器单体工作电压高,不需要进行充放电均衡控制,具有结构简单、成本低、抗振性好、无极性等优点。进行了电动汽车循环工况下的仿真和薄膜电容器样机系统的道路性能实验,分析结果表明:薄膜电容器系统可以用来快速吸收回馈制动能量,也可作为大功率放电下的辅助动力源使用。更多还原

【Abstract】 The electric vehicle usually uses capacitors as auxiliary source to balance loads and to absorb energy recovery braking energy rapidly.Compared with the ultra-capacitors,the film capacitors segment has high volts and no use for the balance of charging or discharging of segment.Hence,it has the advantage of simple structure,low cost,best anti-vibration,no polarity.The results of the simulation of film capacitor applied to EV inputting speed cycle and film capacitor testing indicate that the film capacitor can be used to absorb energy recovery braking energy rapidly and high power discharge.更多还原
