Efficient energy management in battery operated electric vehicle (EV) is important because of limited range caused by low energy density and inadequate energy storage capacity, insufficient charging stations, long charging time, etc. One of the ways to save energy without incurring any additional cost is to follow an optimal driving strategy by a driver because driving harshness consumes lots of energy...
The self-excited synchronous reluctance generator represents a reliable alternative choice to supply electric power to remote communities or for emergency power applications. They are robust, simple, and less expensive compared to other types of brushless generators. However to trigger the self-excitation in stand-alone mode of operation certain criteria must be met. This paper studies the effect...
an optimal driving region (ODR) of electric vehicle (EV) is determined here for changing a speed during acceleration. The ODR which is restricted by two extreme driving points comprises multiple driving strategies (acceleration(s) and the corresponding acceleration duration). ODR was decided by solving an optimization problem that includes three conflicting objectives, minimizing total acceleration...
This work presents a novel urban transportation system based on supercapacitor driven electric vehicle. These electric vehicles will be charged at the bus stops located at a distance of 1–2 kilometres from each other. The bus stops have a large capacity flow batteries that are charged during off-peak hours of the grid. This reduces the stress on the grid during peak hours and drives the transportation...
Electric and Hybrid Electric Vehicle technologies are developing rapidly as a solution to energy and environmental issues. EV/HEV power train system integrates a number of electro mechanical systems and an optimum subsystem design is inevitable to arrive at a practical solution in terms of performance and size of the power train components. Component sizing is essential to meet the performance requirements...
In this paper, a complete simulation model of electric vehicle (EV) is developed by integrating all the subsystems of a PMBLDC motor driven three wheeler EV with basic dynamics of every component involved. This kind of analysis is essential for understanding the correlation between the vehicle control dynamics and the powertrain components. The performance of the entire EV system is evaluated for...
