In order to achieve gradual but timely decarbonisation of the transport sector, it is essential evaluate which types vehicles provide a suitable environmental performance while allowing use hydrogen as fuel. This work compares life-cycle three different passenger cars fuelled by hydrogen: fuel cell electric vehicle, an internal combustion engine car, and hybrid vehicle. Besides, two that in mix...

1 Abstract— Power management strategy is as significant as component sizing in achieving optimal fuel economy of a fuel cell hybrid vehicle (FCHV). We have formulated a combined power management/design optimization problem for the performance optimization of FCHVs. This includes subsystem-scaling models to predict the characteristics of components of different sizes. In addition, we designed a ...

In this paper we present an inexpensive electronic measurement instrumentationdeveloped in our laboratory, to measure and plot the impedance of a loaded fuel cell orbattery. Impedance measurements were taken by using the load modulation method. Thisinstrumentation has been developed around a VXI system stand which controls electroniccards. Software under Hpvee® was developed for automatic measu...

This paper introduces an online and intelligent energy management controller to improve the fuel economy of a power-split plug-in hybrid electric vehicle (PHEV). Based on analytic analysis between fuelrate and battery current at different driveline power and vehicle speed, quadratic equations are applied to simulate the relationship between battery current and vehicle fuel-rate. The power thres...

The paper proposes a Hybrid Electric Vehicle (HEV) design based on the installation of fuel cell (FC) module in existing Daewoo Tico electric vehicle to increase its range urban areas. Installing an FC supplied by 2 kg hydrogen tank would not significantly mass vehicle, and charging time is lower than battery time. For analysis, model was created MATLAB/Simulink software package. simulates at d...

A well-known challenge in computable general equilibrium (CGE) models is to maintain correspondence between the forecasted economic and physical quantities over time. Maintaining such a correspondence is necessary to understand how economic forecasts reflect, and are constrained by, relationships within the underlying physical system. This work develops a method for projecting global demand for...

To improve the drivability and reduce fuel consumption and emissions of an existing sport utility vehicle (SUV), simulation-based vehicle refinement was conducted in this study. A simulation model of the SUV was first established and validated. Both simulation and test results confirm that due to low reserve power both at low and high speed bands, the drivability, fuel economy and emissions of ...

many studies have been done on hybrid vehicles in the past few years. the full hybrid vehicles need a large number of batteries creating up to 300 (v) to meet the required voltage of electric motor. the size and weight of the batteries cause some problems. this research investigates the mild hybrid vehicle. this vehicle includes a small electric motor and a high power internal combustion engine...

Starting from the premise that new consumer value must drive hydrogen-fuel-cell-vehicle (H2FCV) commercialization, a group of opportunities ollectively called “Mobile Electricity” is characterized. Mobile Electricity (Me-) redefines H2FCVs as innovative products able to import and xport electricity across the traditional vehicle boundary. Such vehicles could provide home recharging and mobile p...
