公交车在现代交通系统中占据着重要的角色。纯电动公交车具有低噪声、无污染、能量来源多样化、能量效率高的特点,是解决城市化中的公交车问题的重要途径。但是目前纯电动公交车还存在着续航里程较短、电池价格较高等缺点。而太阳能则是一种高效、清洁、取之不尽用之不竭的能源,捋两者的结合可以在一定程度上缓解一下纯电动公交车的这些缺点。本文就这一问题进行了利用太阳能发电驱动汽车或补充蓄电池电力的研究和针对电源、太阳能发电的整车混合控制系统的设计,从而达到对公交车电源优化增加公交车续驶里程的目的。 相似文献

A virtual prototype of a hybrid electric vehicle (HEV) is created within the virtual test bed (VTB) environment, which has been developed for modeling, simulation, analysis and virtual prototyping of large-scale multi-technical dynamic systems. Attention is focused on the electric system, which is composed of (i) a fuel cell system as a prime power source, (ii) battery and super capacitor banks as energy storage devices for high and intense power demands, (iii) DC-to-DC power converters to control the flow of power, (iv) a three-phase inverter-fed permanent magnet synchronous motor as a drive, and (v) a common DC bus. The simulation of the proposed system is conducted using two types of driving cycles. These are: (i) rapid acceleration and deceleration, and (ii) Federal Urban Driving Schedule (FUDS). The parameter values chosen for the components and the numerical results obtained by simulation are consistent with the practical HEV applications. 相似文献

Top 10 tech cars [hybrid electric vehicles] 总被引:1,自引:0,他引:1
《Spectrum, IEEE》2005,42(3):22-30
A number of new hybrid electric vehicle owners have expressed their disappointment with their purchase because of poor mileage. Official ratings for fuel use, based on the outdated driving patterns of US government test, turned out to be a poor predictor for what typical buyers could expect. Still, though hybrids are hot, no single vehicle is likely to make as much of a splash this year as the revamped Prius did in 2004. The closest thing to a recurring theme in 2005 will be electronic stability control. Among concept cars, hybrid electrics are still going strong, and more of them are being built with lithium-ion batteries rather than the standard nickel-metal hydride. Lithium-ion, now used mostly in consumer electronics, offers close to twice the energy density of nickel-metal hydride. The widest lithium-ion vehicle so fat has to be the luxury-sedan concept Elica from Japan. This paper presents the top ten hybrid cars from different countries. 相似文献

Energy Management for a Residential Microgrid Using Wavelet Transform and Fuzzy Control Including a Vehicle-to-Grid System 下载免费PDF全文
This paper presents the design and implementation of an energy management system (EMS) with wavelet transform and fuzzy control for a residential micro-grid. The hybrid system in this paper consists of a wind turbine generator, photovoltaic (PV) panels, an electric vehicle (EV), and a super capacitor (SC), which is able to connect or disconnect to the main grid. The control strategy is responsible for compensating the difference between the generated power by the wind and solar generators and the demanded power by the loads. Wavelet transform decomposes the power difference into a smoothed component and a fast fluctuated component. The command approach used for fuzzy logic rules considers the state of charging (SOC) of EV, renewable production, and the load demand as parameters. Furthermore, the command rules are developed in order to ensure a reliable grid when taking into account the EV battery protection to decide the output power of the EV. The model of the hybrid system is developed in detail under Matlab/Simulink software environment. 相似文献
