摘要

锂硫(li -硫)电池是市场上现有电池技术的一种很有前途的替代方案。本文研究了一种新型锂- s电池原型在电动城市公交车上的应用。为此，利用MATLAB/Simulink软件，根据伦敦市现有电动公交车的规格，建立车辆模型并进行仿真。根据实验数据，参数化了等效电路单元模型。然后进行电池组尺寸确定，并将Li-S技术与伦敦市现有电动公交车上使用的两种商用锂离子电池进行比较。结果表明，所提出的Li-S电池组在功率方面可以满足电动城市公交车的要求，同时实现车辆续航里程的大幅增加。然而，锂- s电池原型仍然受到有限的循环寿命的影响，这阻碍了这项技术在目前的商业化应用。

How suitable is lithium-sulphur battery for electric city bus application

Lithium-sulphur (Li-S) battery is a promising alternative for the existing battery technologies in the market. This paper investigates application of a new prototype Li-S cell in an electric city bus. For this purpose, MATLAB/Simulink software has been employed to build and simulate a vehicle model according to the specifications of available electric buses in London city. An equivalent circuit cell model is parameterised based on experimental data. Battery pack sizing is then performed and the Li-S technology is compared with two commercial Li-ion batteries used in existing electric buses in London city. The results demonstrate that the proposed Li-S battery pack can fulfil the requirements of an electric city bus in terms of power while achieving a considerable increase in vehicle's range. However, Li-S cell prototypes still suffer from limited cycling life that prevents this technology to be commercialised for such an application at the time being.

期刊介绍： IJPT addresses novel scientific/technological results contributing to advancing powertrain technology, from components/subsystems to system integration/controls. Focus is primarily but not exclusively on ground vehicle applications. IJPT''s perspective is largely inspired by the fact that many innovations in powertrain advancement are only possible due to synergies between mechanical design, mechanisms, mechatronics, controls, networking system integration, etc. The science behind these is characterised by physical phenomena across the range of physics (multiphysics) and scale of motion (multiscale) governing the behaviour of components/subsystems.
