GPS data for a year’s worth of travel by 255 Seattle households illuminate how plug-in electric vehicles can match household needs. The results suggest that a battery-electric vehicle (BEV) with 100 miles of range should meet the needs of 50% of one-vehicle households and 80% of multiple-vehicle households, when charging once a day and relying on another vehicle or mode just 4 days a year.

The power electronics inverter can be considered as the weakest link in an electric drive system, hence the focus of this research work is on the detection of fault conditions of the inverter. A machine learning framework is developed to systematically select torque-speed domain operation points, which in turn are fed to an electric drive model to generate signals for training an artificial neu...

INTRODUCTION RECENT years have seen many different initiatives aimed at bringing about a low-carbon society and it is anticipated that, in the automotive field, HEVs (hybrid electric vehicles) that offer significant improvements in fuel consumption will precede EV (electric vehicles) in becoming the mainstream of future vehicle markets. HEVs achieve low fuel consumption and powerful performance...

The benefits of hybrid electric vehicles have been recognized by the US Army and other military services. As a consequence, hybrid vehicles are being considered as future combat and tactical platforms. In order to achieve this objective, a number of integration challenges need to be overcome for every component system within the vehicle. Energy storage is one of the major systems of concern in ...

The optimal design of hybrid electric vehicle powertrains from a systems perspective is critical to realize the maximum benefits of hybridization for a given application, especially in the heavy-duty vehicle space due to the large number of unique applications. This paper proposes a novel framework that enables parametric design optimization of hybrid electric vehicles while accounting for the ...

Hybrid electric vehicle (HEV) control strategy is a management approach for generating, using, and saving energy. Therefore, the optimal control strategy is the sticking point to effectively manage hybrid electric vehicles. In order to realize the optimal control strategy, we use a robust evolutionary computation method called a “memetic algorithm (MA)” to optimize the control parameters in par...

A series parallel hybrid electric vehicle (HEV) with a conventional internal combustion engine (ICE) and a power split device have been designed using REVS (Renewable Energy Vehicle Simulator) simulation package. REVS has been developed at University of Manitoba to assist in detail studies of different configurations of hybrid electric vehicles (HEV) through visual programming by creating compo...

Electric Vehicle (EV) possesses a significant potential to provide clean energy in vehicular technology. To increase the drive cycle efficiency and the driving range of EVs, which is considered to be the key barrier for its successful commercialization, its energy storage technology needs to be improved. The power requirement of an electric vehicle cannot be satisfied by the battery alone as it...
