Abstract: This paper presents an on-board vehicular battery charger that integrates bidirectional AC/DC converter and DC/DC converter to achieve high power density for application in electric vehicles (EVs). The integrated charger is able to transfer electrical energy between the battery pack and the electric traction system and to function as an AC/DC battery charger. The integrated charger to...

E CONOMIC and environmental incentives, as well as advances in information and control technologies, are reshaping the traditional view of transportation systems. The emergence of plug-in hybrid electric vehicles (PHEVs) and plug-in electric vehicles (PEVs) has shown that electrification is a clear trend to improve performance, efficiency, and sustainability of transportation systems since elec...

Electric vehicle routing problems (E-VRPs) are receiving growing attention from the operations research community. Electric vehicles (EVs) differ substantially from internal combustion engine vehicles. In the routing context, the main difference is due to the limited EV autonomy, which can be recuperated at charging stations. These are rather scarce, thus EVs typically have to perform detours t...

In this study, we demonstrate the contribution of IS-supported demand response (DR) programs to the development of a sustainable transport sector. Based on the energy informatics framework, we develop an IS artifact that can be used to apply DR programs for electric vehicle (EV) fleets. Furthermore, we quantify one DR program in economic terms by analyzing data gathered in an electric mobility ...

The era of sustainable development has brought Electric Vehicles (EVs) to the spotlight. Since recharging an electric vehicle can take up to ten or more times the power consumption of a household, an increasing EV penetration in the market poses a challenge for the electricity companies. Using the Internet of Things (IoT) approach, we propose a model where electric vehicles communicate with the...

The lithium-ion battery is a viable power source for hybrid electric vehicles (HEVs) and, more recently, electric vehicles (EVs). Its performance, especially in terms of state of charge (SOC), plays a significant role in the energy management of these vehicles. The extended Kalman filter (EKF) is widely used to estimate online SOC as an efficient estimation algorithm. However, conventional EKF ...

Electric Vehicles (EVs) require energy storage system that can address its fast changing load requirements such as sudden acceleration or quick regenerative braking by being able to supply or absorb high power as demanded. Lead Acid Batteries, commonly used in cheaper EVs (like electric tempo in Nepal), can properly supply these variable loads and get recharged but this mode of operation drasti...

The economic and environmental benefits brought by electric vehicles (EVs) cannot be fully delivered unless these vehicles are fully or partially charged by renewable energy sources (RES) such as photovoltaic system (PVS). Nevertheless, the EV charging management problem of a parking station integrated with RES is challenging due to the uncertain nature of local RES generation. This paper aims ...

The promotion of hybrid and electric vehicles (EVs) has been proposed as one promising solution for reducing transport energy consumption and mitigating vehicular emissions in China. In this study, the energy and environmental impacts of hybrid and EVs during 2010–2020 were evaluated through an energy conversion analysis and a life cycle assessment (LCA), and the per-kilometer energy consumptio...

There are a number of state and utility policies that reduce total carbon emissions, while shifting emissions from other sectors to power plants. The most significant are policies to expand the use of electric vehicles (EVs) 1 . Increased deployment of EVs will increase electricity consumption and thus will generally increase carbon emissions by utilities but in most states will reduce total ca...
