电动汽车混合储能系统双判据多模式功率分配策略
摘要：针对混合储能系统中电池和超级电容的功率分配问题，提出双判据多模式功率分配策略。以电动汽车的动力学模型为基础，综合直流母线功率和超级电容荷电状态两项参数，动态调整混合储能系统的工作模式；参考储能系统效率模型，调整电池和超级电容的给定功率，实现混合储能系统的功率分配。搭建混合储能系统实验平台，开展电动汽车工况模拟和功率分配策略研究。实验结果表明：与采用固定比例功率分配策略相比，使用双判据多模式功率分配策略可将电池输出功率的均值和峰值分别降低16.98%和24.72%，并且将混合储能系统的能量利用率提升5.35%。

Abstract:To address the issue of the power distribution between battery and supercapacitor in hybrid energy storage system, a multi-mode power distribution strategy with dual criteria is proposed. Based on the electric vehicle dynamics model, the proposed strategy integrates two parameters, the power in the DC bus and the charge state of the supercapacitor, to dynamically switch the working mode of the hybrid energy storage system. The power settings of battery and supercapacitor are adjusted in accordance with the efficiency model of energy storage system. Finally, the power is distributed within hybrid energy storage system. The research on electric vehicle working condition simulation and power distribution strategy was carried out in an experimental platform of hybrid energy storage system. The experimental results indicate that, compared with the fixed proportion distribution strategy, the multi-mode power distribution strategy with dual criteria can reduce the average and maximum power of battery by 16.98% and 24.72% respectively, and enhance the energy utilization rate of the hybrid energy storage system by 5.35% simultaneously.
