Federal electric vehicle (EV) policies in the United States currently include vehicle purchase subsidies linked to EV battery capacity and subsidies for installing charging stations. We assess the costeffectiveness of increased battery capacity vs. nondomestic charging infrastructure installation for plug-in hybrid electric vehicles as alternate methods to reduce gasoline consumption for cars, ...

This paper deals with the potentials of a Hybrid-Excitation Permanent-Magnet (HEPM) machine. The HEPM machine is characterized by rotor including both permanent magnets (PMs) and excitation coils. PMs produce constant flux at air gap machine, while an current supplied so as to regulate such flux. A increase could be necessary during transient overload operations, decrease useful Flux-Weakening ...

Researchers have proposed that fleets of plug-in hybrid vehicles could be used to perform ancillary services for the electric grid. Inmany of these studies, the vehicles are able to accrue revenue for performing these grid stabilization services, which would offset the increased purchase cost of plug-in hybrid vehicles. To date, all such studies have assumed a vehicle command architecture that ...

Vehicles with alternative drive trains are regarded as a promising substitute for conventional cars, considering the growing concern about oil depletion and the environmental impact of our transportation system. However, ―clean‖ technologies will only be viable when they are cost-efficient. In this paper, the environmental impacts and the financial costs of different vehicle technologies are ca...

The charging infrastructure plays a key role in the healthy and rapid development of the electric vehicle industry. This paper presents an energy management and control system of an electric vehicle charging station. The charging station (CS) is integrated to a grid-connected hybrid power system having a wind turbine maximum power point tracking (MPPT) controlled subsystem, photovoltaic (PV) MP...

Hybrid energy storage system (HESS) can be adopted in hybrid, plug-in hybrid, and pure electric vehicles (HEV, PHEV, and EV), where a bidirectional DC-DC converter (BDC) is used to connect batteries and ultra-capacitors. The efficiency improvement of the BDC is beneficial to increase the efficiency viability of HESS. Due to ZVS, high efficiency can be obtained at heavy load operations while the...

An in-wheel motor electric vehicle has high unsprung mass because of its in-wheel motor, which decreases vehicle ride comfort and vehicle safety. This paper presents a controllable suspension employing an optimal design hybrid damping control strategy based on ideal skyhook and groundhook as a reference. A sliding mode controller is designed to make the plant track the ideal reference model. Th...

Vehicle simulation software is essential to vehicle design and development. Most current vehicle software simulations, however, require that components be specified prior to running the simulations. Within this context, this paper presents a simulator offering to users flexibility enough to add new component and use different level of accuracy. Thus a first version of a new software tool, in or...

−Hybrid electric vehicles (HEV) utilize electric power and a mechanical engine for propulsion; therefore, the performance of HEVs is directly influenced by the characteristics of the energy storage system (ESS). The ESS for an\ HEV generally requires high power performance, long cycle life, reliability and cost effectiveness; thus, a hybrid energy storage system (HESS) that combines different t...
