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...

For years the interest of the University of Roma 1 (UDR1) research group has been focused on the development of a Hybrid Series vehicle (called Lethe), different from standard ones, thanks to the use of a Gas Turbine (GT) set as a thermal engine. The reason for this choice resides in the opportunity to reduce weight and dimensions, in comparison to a traditional Internal Combustion Engine. It’s...

This paper is the second of a two part study which quantifies the economic and greenhouse performance of conventional, hybrid and fully electric passenger vehicles operating in Australian driving conditions. This second study focuses on the life cycle greenhouse gas emissions. Two vehicle sizes are considered, Class-B and Class-E, which bracket the large majority of passenger vehicles on Austra...

1. What is a Hypercar® vehicle? 2. How could Hypercar® vehicles attain such dramatically improved fuel economy? 3. Would there be tradeoffs in performance or styling? 4. Why a hybrid-electric instead of a battery-electric vehicle? 5. What fuels would Hypercar® vehicles use? 6. Are fuel cells being considered in Hypercar® vehicles? 7. Why advanced composites? 8. Would Hypercar® vehicles be safe?...
