Electric vehicle, as a clean energy industry, is an important branch. Electric vehicles not only are the energy of the electric user, but also can be used as mobile and distributed energy storage unit to the grid. As a precondition of safety operation for power grid, studies of EVs’ charging load characteristics is also the theoretical basis of intelligent scheduling EVs charging orderly. This ...

A study on plug-in electric vehicle (PEV) charging load and its impacts on distribution transformers loss-of-life, is presented in this paper. The assessment is based on residential PEV battery charging. As the exact forecasting of the charging load is not possible, the method for predicting the electric vehicle (EV) charging load is stochastically formulated. With the help of the stochastic mo...

Known barriers of Electric Vehicles (EVs) include their limited range and, to some extent, the underdeveloped charging infrastructure. This position paper presents initial results from a field study investigating the experience of EV drivers who are supported by a newly developed charging concept (ELVIIS) consisting of a web, smartphone and in-vehicle application. By connecting power grid owner...

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...

While electric vehicles (EV) are already widespread in particular applications, e.g. fork lifts or baggage carrying (cf. Rand et al., 1998), their use as individual motor cars is still limited. E.g., only 2,300 EV were registered in Germany on 1st of January 2011 (Federal Motor Transport Authority, 2011). However, many drivers lead towards an electrification of individual motor car traffic all ...

With today’s electric charging technology, charging time of an electric vehicle (EV) is much longer than that for a gasoline vehicle, and therefore the queueing effect at an EV charging station (CS) may be serious. That is, when an EV arrives at an overloaded CS, it is likely that the EV will wait for a long time before it is charged. This paper investigates the waiting problem for EV charging....

The rapid transition from conventional vehicles to electric (EVs) has created a significant demand for vehicle charging infrastructure. availability of adequate EV infrastructure is crucial meet this and support the widespread adoption EVs. However, users often face challenges in accessing information about providers, limiting their ability plan longer journeys effectively. In response issue, r...

Electric vehicle (EV) aggregator, as an agent between the electricity market and EV owners, participates in the future and pool market to supply EVs’ requirement. Because of the uncertain nature of pool prices and EVs’ behaviour, this paper proposed a two-stage scenario-based model to obtain optimal decision making of an EV aggregator. To deal with mentioned uncertainties, the aggregator’s risk...
