摘要

基于锂离子电池与超级电容器的混合储能系统的运行效率和整体储能系统的老化，本文旨在评估锂离子电池与超级电容器混合储能系统对电动汽车储能系统的增强作用。由于超级电容器的高功率密度和小内阻，混合储能系统带来了理想的改进。然而，超级电容器的能量密度低于典型的电动汽车电池，这使得两种存储系统的结合成为增加电动汽车行驶里程和电池寿命的有希望的突破。因此，在本工作中使用MATLAB/Simulink工具建立仿真场景，以研究所提出的混合存储系统的运行情况。

Assessing Efficiency and Aging of Lithium-Ion Battery in a Hybrid Energy Storage System

This paper aims to assess the enhancements of the electric vehicle (EV) energy storage systems by hybridizing Lithium ion (Li-ion) battery with a supercapacitor, based on their operation efficiency and the aging of the overall storage system. The hybrid energy storage system brings desired improvements due to the high power density and small internal resistance of supercapacitors. However, the energy density of a supercapacitor is lower than that of a typical EV battery, making the combination of the two storage systems a promising breakthrough to increase both EV mileage and battery lifetime. Accordingly, MATLAB/Simulink tools are used in this work to set-up simulation scenarios to investigate the operation of the proposed hybrid storage system.
