The adaptive power management strategy is developed for a four-mode plug-in hybrid electric vehicle in this paper. For a given driving pattern, dynamic programming is employed to obtain the global optimum as the performance upper bound to benchmark the proposed strategy. A selforganizing fuzzy controller is used to adaptively adjust the equivalence factor for converting the electric power usage...

The electrification of transport systems requires a change in the composition vehicle fleet towards higher shares electric vehicles. A successful transition, however, depends on many factors which some relate to purchase prices and features, while others technology charging infrastructure. This paper analyses transition plug-in We use data from large representative Danish stated choice survey. ...

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...

Plug-in hybrid electric vehicles (PHEVs) have the ability to drastically reduce petroleum use. The FreedomCAR Office of Vehicle Technology is developing a program to study the potential of this technology. This paper describes work in which several tools were used to evaluate the impacts of various parameters on PHEV fuel economy. First, the impacts of battery’s energy and power were evaluated ...

Electric Vehicles (EVs) have been extensively researched to reduce the fuel consumption and tailpipe emission. The series-parallel power-split Plug-in Electric Vehicle (PHEV) has been considered as one of the most suitable candidates. It contains both an internal combustion engine (ICE) and an electrical storage system (ESS) to achieve a better driving performance. The energy management system ...

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...

This paper presents an evaluation of battery requirements for hybrid and electric city buses. Technical specifications of recently developed lithium based batteries and vehicle simulation results are used as basis for the evaluation. The battery requirements are evaluated in terms of power and energy capacity, calendar and cycle life as well as costs. Conventional diesel, parallel and series hy...

A critical element to the success of new propulsion technologies that enable reductions in fuel use is the integration of component thermal management technologies within a viable vehicle package. Vehicle operation requires vehicle thermal management systems capable of balancing the needs of multiple vehicle systems that may require heat for operation, require cooling to reject heat, or require...

Hybrid electric vehicles, plug-in hybrid electric vehicles, and battery electric vehicles offer the potential to reduce both oil imports and greenhouse gases, as well as to offer a financial benefit to the driver. However, assessing these potential benefits is complicated by several factors, including the driving habits of the operator. We focus on driver aggression, i.e., the level of accelera...
