摘要:

为了提高电动汽车动力蓄电池能效,增加电动汽车的启动功率,设计了一种电动汽车用五自由度主动悬浮控制的磁悬浮飞轮电池储能系统,阐述了系统的悬浮控制原理,并结合一种数字比例-积分-微分(PID)控制算法建立了该磁悬浮飞轮径向单自由度传递函数。仿真分析了该传递函数的频谱特性及飞轮转子的运动轨迹曲线,实现了对磁悬浮飞轮电池样机30000r/min的旋转实验。实验结果表明:该磁悬浮飞轮转子可以高速稳定旋转,具有良好的储能能力;可以辅助电动汽车原动力蓄电池工作,有助于提高原动力电池的充放电性能以及延长原动力蓄电池的使用

Abstract:

In order to improve the energy efficiency of electric vehicle(EV)power battery and increase the start-up power of EV,a maglev flywheel battery energy storage system with the active suspension controlled at five degrees of freedom is designed for EV.The system suspension control principle is expounded,and the radial single freedom transfer function of the maglev flywheel is established by referring to a digital proportion-integral-differential(PID)control algorithm.The frequency spectrum characteristic of the transfer function and the flywheel rotor trajectory curve are simulated,and the30000r/min rotation experiment on the maglev flywheel battery prototype is realized.The experiment results show that the maglev flywheel rotor is capable of high speed steady spin,and with good energy storing ability.The maglev flywheel battery energy storage system will assist the EV power battery work,improve the battery charge and discharge properties and prolong the service life of the motive power battery.
