The rise of electric vehicles brings a number of challenges for our infrastructure and energy security. Waraich (Waraich et al., 2009) demonstrates that bad choices of charging times made by the owners of electric vehicles (EVs) or plug-in hybrid electric vehicles (PHEVs) can lead to severe problems for the electric grid due to peak loads. Coordinated charging decisions controlled by a centrali...

The paper presents a number of advanced solutions on electric machines and machine-based systems for the powertrain of electric vehicles (EVs). Two types of systems are considered, namely the drive systems designated to the EV propulsion and the power split devices utilized in the popular series-parallel hybrid electric vehicle architecture. After reviewing the main requirements for the electri...

This study investigates the economic validity of the diffusion of fuel cell vehicles (FCVs) and all-electric vehicles (EVs), employing a cost-benefit analysis from the social point of view. This research assumes the amount of NOx and tank-to-wheel CO2 emissions and gasoline use reduction as the benefits and the purchase costs, infrastructure expenses, and maintenance costs of alternative vehicl...

We develop a multi-period capacitated flow refueling location problem for electric vehicles (EVs) as the EV market responds to the charging infrastructure. The optimization model will help us determine the optimal location of level 3 chargers as well as the number of charging modules at each station over multiple time periods. Our model can also be applied to fast-filling gaseous alternative fu...

Li-excess layered oxide high energy density materials are currently being considered as promising candidates for energy storage technologies in plug-in hybrid electric vehicles (PHEVs) or electric vehicles (EVs), owning to their high capacity (>250mAh/g), high energy density, and excellent safety.[1-3] Two major fundamental questions, however, must be resolved before their commercial implementa...

The introduction of plug-in hybrid electric vehicles (PHEVs) and electric vehicles (EVs), commonly referred to as plug-in electric vehicles (PEVs), could trigger a stepwise electrification of the whole transportation sector. However, the potential impact of PEV charging on the electric grid is not fully known, yet. This paper presents an iterative approach, which integrates a PEV electricity de...

Takashi Kimura Ryuichi Saitou Kenji Kubo Kinya Nakatsu Hideaki Ishikawa Kaname Sasaki OVERVIEW: Green vehicles have become familiar sights on the road in recent years, with growing sales of HEVs and the arrival of the fi rst mass production BEVs. With environmental regulations on CO2 (fuel economy) and exhaust emissions also becoming increasingly stringent, sales of these green vehicles are set...

For Electric Vehicles (EVs), Weight and losses reduction are important factors not only in reducing the energy consumption and cost but also in increasing autonomy. This paper describes the application of an evolutionary algorithm for multiobjective optimization in the traction chain (TC) of pure EV. In this study, the optimisation algorithm is based on the Strength Pareto Evolutionary Algorith...

In this paper, the impact of charging a large number of electric vehicles (EV) on the power system voltage stability is investigated on an example of a real power transmission system. First, the maximum load factors for different states in a selected part of the power system are determined using the continuation power flow (CPF) calculations and PV curves. The approach provides information abou...

Both governments and car manufacturers have recently made huge investments in electric vehicles (EVs) to turn them into a viable solution to cope with problems such as pollution due to internal combustion engines and increasing gas prices. For instance, the Renault-Nissan Alliance has invested 4 billion in EVs since 2010. In particular, they signed a partnership with Better Place, a company tha...
