摘要
针对混合动力汽车和纯电动汽车对高能量密度电能存储系统的需求,建立了高比功率超级电容和高比能量蓄电池复合使用的复合电源系统。在复合电源架构的基础上,结合复合电源4种不同的工作模式,采用动态规划算法管理复合电源能量分配,搭建了基于双向DC/DC变换器的实验平台,利用任意波形发生器模拟不同工况。实验结果表明,动态规划算法能有效地优化复合电源系统能量管理策略。
In view of the demand of hybrid electric vehicles and pure electric vehicles for high energy density power storage system,a composite power supply system with the compound use of the high specific power super capacitor and high specific energy storage battery is established.Based on the composite power supply architecture,and combined with four different working modes of the composite power supply,the dynamic programming algorithm is used to manage the energy distribution of composite power supply.An experimental platform based on the bidirectional DC/DC converter is built,and the arbitrary waveform generator is used to simulate the different working conditions.The experimental results show that the dynamic programming algorithm can effectively optimize the energy management strategy of the hybrid power supply system.
