摘要
通过对飞轮电池能量特性的研究计算并综合考虑其使用成本,分析了其在混合动力汽车上应用的可行性。基于MATLAB/Simulink建立飞轮电池模型并仿真,根据飞轮电池的能量特性将飞轮转速限制在低能量损耗区间内。仿真结果表明,飞轮电池的能量特性适用于混合动力汽车,相关储能状态参数的引入使飞轮电池的能量储存状态可以通过对飞轮瞬时转速的测量进行精确计算,从而更加有利于混合动力系统的综合控制。
The feasibility of flywheel battery to be used for hybrid electric vehicle is analysed through study on both the energy characteristic of flywheel battery and its use cost.Based on MATLAB/Simulink,the model of flywheel battery is established and simulated,and the rotational speed of flywheel is limited in the low energy-consumption area according to energy characteristic of flywheel battery.The simulation results indicate that the energy characteristic of flywheel battery is suitable for hybrid electric vehicle,and the introduced parameters of energy storage state make the energy storage state of flywheel battery be calculated accurately by measurement of instantaneous rotational speed of flywheel,so it is more helpful for the control of hybrid system.
