In distribution networks, failure to smooth the load curve leads to voltage drop and power quality loss. In this regard, electric vehicle batteries can be used to smooth the load curve. However, to persuade vehicle owners to share their vehicle batteries, we must also consider the owners' profits. A challenging problem is that existing methods do not take into account the vehicle owner demands ...

Lithium batteries have been widely used as a power source for numerous small devices such as mobile phones and laptop computers. Recently, the lithium battery is expected to be used as a power source for electric vehicles. For the electric vehicles application, an improvement of energy and power densities and safety is required. In this review, a brief explanation of structure and mechanism of ...

Given the limited driving range of battery electric vehicles and lack of sufficient charging infrastructure, locating charging stations is an important decision problem to enable long-distance travels by battery electric vehicles. This paper considers an important political factor in such location problems: the equitable access to charging stations among geographical regions. We propose three t...

Lithium-ion secondary batteries are commonly used in electric vehicles, smart phones, personal digital assistants (PDA), notebooks and electric cars. These lithium-ion secondary batteries must charge and discharge rapidly, causing the interior temperature to rise quickly, raising a safety issue. Over-charging results in an unstable voltage and current, causing potential safety problems, such as...

Very high values of efficiency in electric power conversion, electric energy saving requirements and power converter component optimization are priorities in design and construction of any type of modern power electronic converters. Moreover, if such power converters are connected to battery power source or other "weak" power source (as, for instance, fuel cells), additional design problems app...

Electric vehicle charging in the distribution network is one of the common techniques for technical and economic management of energy distribution, which, if implemented properly, will bring several benefits such as reducing network peak load, charging costs reduction, loss minimization, and etc. In most traditional charging methods, the constraints of fully charging electric vehicles at depart...

The charging infrastructure plays a key role in the healthy and rapid development of the electric vehicle industry. This paper presents an energy management and control system of an electric vehicle charging station. The charging station (CS) is integrated to a grid-connected hybrid power system having a wind turbine maximum power point tracking (MPPT) controlled subsystem, photovoltaic (PV) MP...

Electric vehicles are by many seen as the cars of the future as they are high efficient, produces no local pollution, are silent, and can be used for power regulation by the grid operator. However, electric vehicles still have critical issues which need to be solved. The three main challenges are limited driving range, long charging time, and high cost. The three main challenges are all related...
