摘要

摘要考虑到锂电池的衰减，确定了电动公交车牵引动力装置储能缓冲器的能效。在 MATLAB/Simulink 中合成了电动公交车能源系统的仿真模型，并比较了不带缓冲储能装置和带基于钛酸锂电池的不同容量缓冲储能装置的能源系统仿真结果。使用占总容量 14.47% 的储能缓冲器将使电池寿命延长 32.7%。

Determination of the Parameters of the Buffer Storage of an Electric Bus Taking into Account the Degradation of the Lithium Battery

Abstract

The energy efficiency was determined of the energy storage buffer of the traction power unit of an electric bus taking into account the degradation of the lithium battery. A simulation model of the energy system of an electric bus was synthesized in MATLAB/Simulink, and the results of simulation of the energy system without a buffer storage and with a buffer of various capacities based on a lithium titanate battery were compared. The implementation of an energy storage buffer with 14.47% of the total capacity of the storage will increase the battery lifetime by 32.7%.
