Due to rising fuel costs, the substantial price for CO 2 emissions and decreasing wind power costs, wind power might become the least expensive source of power for an increasing number of power systems. This poses the questions of how wind power might change optimal investments in other forms of power production and what kind of means could be used to increase power system flexibility in order...
An accurate battery State of Charge estimation is of great significance for battery electric vehicles and hybrid electric vehicles. This paper presents an adaptive unscented Kalman filtering method to estimate State of Charge of a lithium-ion battery for battery electric vehicles. The adaptive adjustment of the noise covariances in the State of Charge estimation process is implemented by an idea of...
The number of electric vehicles in China is expected to grow rapidly, triggering the nationwide large-scale construction of charging stations. At the same time, a reasonable charging price has not been established. This article records the views of station operators and EV users and calculates a charging pricing range. The price should not only ensure the profit of operators, but also help reduce...
This paper examines a TMS (thermal management system) of a range-extended EV (electric vehicle), which operates on its battery before the gasoline engine engages. In this period of independence of the ICE (internal combustion engine), the vehicle performance characteristics such as range, power for acceleration, fuel economy and emissions depend solely on the battery performance. Since the magnitude...
Starting on the 24th of April, 2011, the Romanian government offered to subsidize all potential buyers of electric vehicles, both private and corporate, offering 25% off of the retail price up to 5000 euros with no pollution tax. The Romanian government encourages all governmental institutions to consider buying electric vehicles when deciding to change their existing vehicles stock. This decision...
Transport activity has been a key facilitator and driver of economic prosperity in Lithuanian (hereinafter LIT) and it is likely to continue to grow. It can produce both positive and negative effects on the quality of life and the environment depending on country-specific circumstances.This research paper sets the stage for a look at the LIT passenger vehicle fleet and its transition towards sustainable...
The battery cooling/heating with active methods is required for EVs (electric vehicles) in the extreme temperature conditions. This work presents a new active battery cooling/heating method based on PCS (phase change slurry) cycle. Two typical often used active cooling/heating methods so-called the direct cabin air blow and refrigerant circulation are also illustrated in detail. The thermodynamic...
The anticipation of a large penetration of EVs (electric vehicles) into the market brings up many technical issues. The power system may put at risk the security and reliability of operation due to uncontrolled EV charging and discharging. It is necessary to carry out intelligent scheduling for charging and discharging of EVs. In this paper, a smart management and scheduling model is proposed for...
The BSS (battery swapping station) is a newly proposed mode of supplying power to the EV (electric vehicle). Different from the BCS (battery charging station), the BSS prepares the batteries for EVs in advance and could complete the battery swapping in a short time. The operations designed for the BCS are not appropriate for BSS anymore and the researches about BSS are at the early stage. In this...
The massification of electric vehicles (EVs) can have a significant impact on the power system, requiring a new approach for the energy resource management. The energy resource management has the objective to obtain the optimal scheduling of the available resources considering distributed generators, storage units, demand response and EVs. The large number of resources causes more complexity in the...
As electric vehicles offer a promising choice to deal with the growing air pollution and the global consumption of fossil fuels in the future smart grids, integrating their full benefit in the power system should be of a high priority. Numerous studies surveyed the possibility of charging/discharging modes of vehicles such as vehicle-to-grid, grid-to vehicle and vehicle-to-building and one introduced...
This paper presents the EB (energy box) concept in the context of the V2G (vehicle-to-grid) technology to address the energy management needs of a modern residence, considering that the available infrastructure includes micro-renewable energy sources in the form of solar and wind power, the electricity loads consist of “smart” and conventional household appliances, while the battery of an EV (electric...
EVs (Electric vehicles) have garnered much of attention over the past few decades as a promising solution to greenhouse gases in transportation. In this paper, a feasibility study is performed applying a TE (thermoelectric) device to the energy storage system of an electric vehicle. By applying a TE device to the Li-family battery system, the effectiveness of the TE device for possible cooling or...
The main design criteria for the modern sustainable development of vehicle powertrains are the high energy efficiency of the conversion system, the competitive cost and the lowest possible environmental impacts.An innovative decision making methodology, using multi-objective optimization technics is currently under development.The idea is to obtain a population of possible design solutions corresponding...
In this paper we address the current European Union's support policy for BEV (battery electric vehicles) manufacturing under the Super-credit modality, and its actual relationship with the reduction of carbon emissions derived from the use of battery electric vehicles (BEV). Particularly, we have estimated the BEV associated carbon emissions through the method provided by Intergovernmental Panel on...
Electric vehicle charging by renewable energy can help reduce greenhouse gas emissions. This paper presents a data-intensive techno-economic model to estimate the cost of charging an electric vehicle with a battery capacity of 16 kW h for an average travel distance of 65 km from small-scale renewable electricity in various jurisdictions in Canada. Six scenarios were developed that encompass scale...
National demand for electricity follows a regular and predictable daily pattern. This pattern is set to change due to efficiency improvements, de-industrialisation and electrification of heat and transport. These changes are independent of renewable infeed and are not well understood: contemporary studies assume that electricity load curves will retain their current shape, scaling equally in all hours...
Battery electric vehicles (BEVs) and fuel cell electric vehicles (FCEVs) are increasingly prevalent in the transportation sector due to growing concerns about climate change, urban air pollution and oil dependence. This theoretical study reports the results of well-to-wheel (WTW) analyses for BEVs and FCEVs in different energy resource and technology pathways in China in terms of fossil energy use,...
One of the most promising strategies recommended for increasing energy security and for mitigating transportation sector emissions is to support alternative fuel technologies, including electric vehicles. However, there is a considerable amount of uncertainty regarding the market penetration of electric vehicles that must be accounted for in order to achieve the current market share goals. This paper...
The national and municipal government of China enacted a series of regulations and policies to stimulate/promote the development of new energy vehicles, in order to mitigate the increasingly serious carbon emissions, environmental pollution, and energy shortage. As a large metropolitan and populated city subject to the notorious air pollution, Beijing has been making a remarkable progress in the large-scale...
