Abstract:

The driving force of an electric traction vehicle depends on the vehicle's power and the amount of electricity consumed. However, a particularly important parameter in the 3 kV DC traction is the voltage on its pantograph, which closely connects the traction vehicle and the power system. In turn, the voltage level depends on the power supply parameters of the railway line and the quantity as well as quality and location of other electric traction vehicles in the considered area. The article presents a digital model of movement for electric traction vehicles in the given power supply area.

Abstract:

With the world seeking ways to cope with climate change, the interest in and demand for electric vehicles are increasing as part of the efforts to resolve the issue of fine dust, especially in South Korea. The Korean government has consistently announced plans to promote electric vehicles as a means of transportation by providing benefits such as subsidies for electric vehicle purchase and expansion of charging infrastructure. Meanwhile, as electric vehicles continue to grow in number, the energy industry has become attentive to its role as a resource for power generation through vehicle to grid technology. This study analyzes electric vehicle consumer preferences using the discrete choice experiment (DCE) and found that there exists a clear nested structure in Korean consumers’ choice of vehicle. The study also estimates the amount of vehicle to grid electricity supply in the power market and calculates not only national but also individual economic benefit of electric vehicle owners participating in vehicle to grid services based on the estimated amount of electricity supplied. The results of scenario analysis indicate that the estimated electric vehicle supply in Korea will be about 560,000 units cumulatively and that the vehicle to grid electric vehicle power supply scale will reach 1.81 GW by 2030. The estimation shows that the economic benefit of vehicle to grid at the national power market level is 50.9 billion KRW per year, while the economic benefit at an individual level (per vehicle) is 104,151 KRW.

Abstract:

Introduction. In linear traction drives of high speed vehicles moving with velocities about 350 - 450 km/h it is expedient to use synchronous motors with stator winding located on track structure and constant magnetic field sources (permanent magnets, superconducting windings or bulk superconductors) located on the vehicle. Such high speed traction system does not require the moving contact for its power supply and it means a considerable advantage of system. Lack of a moving contact on the vehicle involves also the use of contactless system for auxiliary power supply. Purpose. The purpose of the paper is to analyze the versions of contactless auxiliary energy consumers power supply of high speed maglev vehicles with synchronous traction motors. Method. Weight, size and energy parameters of maglev vehicles power supply sources for auxiliary consumers are discussed and their areas of use are analyzed. Results. For contactless power supply of auxiliary energy consumers of maglev vehicles with electrodynamic suspension it is expedient to use linear induction generators and rechargeable batteries. For maglev vehicles with electromagnetic suspension it is expedient to use linear generators, linear transformers and rechargeable batteries. Practical significance. Results may be used for creation of national commercial high speed maglev transport. Conclusion. The choice of combination of power supply sources for auxiliary consumers is determined by vehicle magnetic suspension type. For vehicles with electromagnetic suspension it is expedient to use linear transformers, linear induction generators and rechargeable batteries. For vehicles with electrodynamic suspension use superconducting magnetic systems it is expedient to use linear generators and rechargeable batteries.

Abstract:

Certified electric vehicle power converters can inject DC current into the AC grid if they fail. Verification of DC injection by electric vehicle supply equipment can be a cost-effective extra measure to ensure power quality from a variety of plugged-in electric vehicles. As electric vehicle supply equipment typically performs high-accuracy revenue energy metering, we propose that measurement of AC current and DC injection with a single sensor is the most economically efficient design. This article presents an integrated shunt current sensing system with separation of AC and DC signals for concurrent revenue metering and DC injection detection. It also shows how the combined sensor is integrated into 19.2 kW single-phase electric vehicle supply equipment, and outlines how the design would be extended to 100 kW three-phase electric vehicle supply equipment. The prototype can detect DC injection of ≥400 mA in an AC current up to 80 A in accordance with the IEEE 1547-2018 standard. The prototype can also conduct revenue metering within the 1.0 accuracy class. The prototype does not have high power dissipation at high currents typical for shunt systems. Finally, the prototype is less costly than common electric vehicle supply equipment revenue metering CT systems with the addition of the popular Hall-effect sensor.

Abstract:

Advanced Driver Assistance System (ADAS) and Automated Driving (AD) are the two major topics for the current and next generations of vehicles. To realize them in full-size vehicles equipped with a 12 V power supply, the need for electric power steering (EPS) is increasing. Currently, the steering system of full-size vehicles is equipped with hydraulic power steering due to electric power shortage. An auxiliary power supply system using a lithium-ion capacitor was developed in order to solve the concern. In addition, to mount the system in the vehicle with no cooling–heating equipment, development of expanding the operating temperature range of the lithium-ion capacitor was conducted. Several improvements have made the capacitor operate stably in high-temperature environments above 100 °C.

Abstract:

Under the background of severe air pollution and energy shortage, electric vehicles (EVs) are promising vehicles to support green supply chain and clean production. In the world, the renewal of EVs has become a general trend. Therefore, the concern about EVs is a hot issue at present, but EVs have the characteristics of limited driving distance and long charging time. When the EVs are used in logistics transportation, these characteristics have a significant impact on the vehicle routing problems. Therefore, based on the research experience of traditional vehicle routing optimization, combining with the characteristics of EVs, this paper presents an optimal problem of electric vehicle routes with time windows based on two charging methods and it also designs a mathematical model which was caused by early and late arrival as the objective function to minimize the transportation cost, vehicle use cost, power supply cost, and penalty cost. The model is solved using an ant colony algorithm. Finally, the ant colony algorithm is tested and analysed with an example.

Abstract:

The increase of rail vehicles speed, as well as the increase of their power, puts high demands on the power delivery system for traction vehicles The most critical point in the vehicle's power supply circuit is the contact between the current collector and contact wires. Ensuring a reliable co-operation of the current collector and contact line, requires technical development of the contact line and current collector construction, as well as improvement of diagnostic systems of these components. This is translated into the need to develop new measurement methods, which allow for more complete definition of the parameters of these elements of traction vehicle power supply system. Each new measurement method requires verification, performed by calibrating or comparing the results with another measurement method which has already been tested. The article presents results of experimental verification of a visual method for measuring the displacement of contact wires, with a proven method based on short range laser rangefinders and calliper as reference measurement.

Abstract:

The traditional vehicle power supply is unable to meet the power requirement of electric power steering system (EPS) in heavy-duty vehicles at low speeds. A novel EPS with hybrid power supply (HP-EPS) is constructed in this paper, and a new optimized rule-based energy management strategy of hybrid power supply system is designed. The strategy determines the power distribution of the vehicle power supply (VPS) and super capacitor (SC), as well as the charging or discharging of SC. Furthermore, to minimize the output current fluctuation of the VPS, the optimization model of parameters in the strategy is established and the particle swarm optimization algorithm (PSO) algorithm is applied to optimize the rules in the energy management strategy. The verification for the designed energy management strategy is carried out in MATLAB/Simulink and results show that the output current peak of VPS decreases by 33% and its fluctuation depresses significantly. In addition, the SC is charged timely and fast, which is beneficial to guarantee enough state of charge (SOC) of SC. In conclusion, the optimized rule-based energy management strategy used for the HP-EPS system can meet the current requirement of EPS and effectively reduce the peak and fluctuation of the VPS output current.

In this paper, the system structure and the theoretical model are analyzed, and the mathematical model of the system vibration frequency and the piezoelectric output have been put forward, then a piezoelectric energy harvesting device is designed on the basis of simulation analysis. Experiments have been done to test the performance of its power generation in the case of resonance. The results showed that the theoretical model proposed in this paper can be a good predictor of the output characteristics of the system. As the resonance frequency is 16.5 Hz, acceleration is 0.5g, the maximum open circuit voltage of the system obtained is 3.5 volts, the optimum load resistance is 425kΩ, and the vibration energy collection device maximum load power is 14 uW. Conclusion: Greater energy could be caught to meet the vehicle sensor power supply needs with the use of super capacitor.

Abstract:

The technology of power electronic systems has diversified into industrial, commercial, and residential areas. Developing a strategy to improve the performance of the electrical energy of an electric vehicle (EV) requires an analysis of the model that describes it. EVs are complex mechatronic systems described by nonlinear models and, therefore, its study is not an easy task. It can improve the performance of a battery bank by creating new batteries that allow for greater storage or by developing a management energy system. This article shows the development of a power supply management system based on fuzzy logic for an electric vehicle, in order to minimize the total energy consumption and optimize the battery bank. The experimental result is shown using the fuzzy controller under standard operating conditions. An increase in battery performance and overall performance of energy consumption is shown. Speed signals acquired show improvements in some dynamic, such as overshoot, settling time, and steady-state error parameters. It is shown that this fuzzy controller increases the overall energy efficiency of the vehicle.

Abstract:

Evaluating the possible impact on power system of a large number of electric vehicles (EVs) is becoming of great interest. With the development of V2G technology, electric vehicles constitute a significant power reserve. In addition, batteries in electric vehicles may be used to provide storage capability for energy produced by renewable sources and to supply auxiliary services to the grid. The paper presents the preliminary results of an on-going project aimed at evaluating the impact of electric vehicles on power system. The simulation results shows significant benefits of V2G on the daily load profiles and network planning. Hypotheses such as battery size, number of users, load profiles without and with different EV penetration are presented for successive scenarios set-up and simulations.

Abstract:

this paper establishes the revenue functions of both electric vehicle users(EV users) and power company, further analyzes users’ intention to reserve power and the feed-in tariff strategy of power company with CVaR criterion, for better V2G( vehicle to grid) reserve power supply coordination. The simulation shows that the users tend to reserve a specific quantity of power which is equal to the expected lowest reverse power supply in the condition of high risk aversion degree; however it will increase with the rise of feed-in tariff when the degree is low. In addition, the double marginalization which occurs in the reverse supply chain of V2G reserve power results in that the optimal reserve power of users cannot achieve the maximum mutual profit, in decentralized decision mode. Therefore two different coordination strategies for users with different risk aversion are proposed in this paper.

Abstract:

Automatic Vehicle Classification (AVC) detector, among traffic data collection devices, is very useful but operation failure or damage is often occurred due to unstable power supply, weather changes and poor road pavement condition, causing deteriorated data quality. In case of AVC detector currently used for detecting the vehicle type, 2 or more detectors are installed at the sections with similar traffic pattern, causing unnecessary cost. This study thus is intended to identify the problems with existing vehicle detector so as to develop the improved detector as well as evaluate the performance. This study is intended to identify the problems with existing vehicle detector and develop and evaluate the improved detector. The failure with AVC detector was mostly attributable to unstable power supply and environmental change and complex sensor and controller results in the high cost. Thus, to stabilize the power supply and reduce the failure by environmental change, improvement of the control part and enclosure was made and the cost was reduced by simplifying the sensor and control system and as a result of test, data accuracy, power stability and cost reduction could be achieve, proving high potential applicability to the site in the future.

Abstract:

Trolleybus type power supply using a two-pole overhead catenary system has been used for over one hundred years. However, energy demand in this type of road transport is the lowest. The main disadvantage of this type of transport is the lack of flexibility. Road electric vehicles equipped with batteries, which are now more and more often being put into service, allow for autonomous run on the roads without overhead contact wires. Therefore, it is possible to use them in a more flexible manner. The main problem is a limited range of autonomous run and long charge time of batteries. The paper presents a concept consisting in the application of an overhead catenary for supplying electric and hybrid vehicles (including automobiles) when a vehicle is in motion (mobile charging). Electric trucks are equipped with controlled current collectors allowing for connection with an overhead catenary during driving. Application of this solution to automobiles is rather impossible, which prevents them from being supplied directly from a catenary. The basis of the original concept presented in the paper is the creation of automobile convoys supplied via a truck equipped with current collectors. A description of the proposed system and an algorithm of its operation are presented in the paper. The discussed transport system has significant advantages in comparison to completely autonomous electric vehicles: increased range of driving with lower capacity of batteries on board and flexibility of use, longer life-time of batteries, lower energy consumption. The paper compares the proposed system with the currently used ones, which employ charging of automobiles during stops, but also underlines the advantages of the first solution.

Abstract:

This paper presents the computer simulation model of a grid to vehicle (G2V) wireless power supply using a single-phase matrix converter (SPMC). The proposed system uses the SPMC that operates as a direct AC-AC converter to convert the supply frequency of 50 Hz to reach 20 kHz output frequency. The use of 20 kHz frequency is suitable for wireless power transfer (WPT) operation in order to obtain higher power transfer efficiency between the transmitter and the receiver parts. An advanced of the proposed circuit topology can solve the conventional system for G2V circuit topology that uses multiple stages of power conversion system, resulting in high power semiconductor losses that could lead to low efficiency. In this work, multiple stages of the conventional "AC-DC-AC" circuits have been reduced to a single power conversion stage by using the SPMC circuit topology. The use of the proposed circuit topology can reduce the number of devices, thus reduce the semiconductor losses. A part of reducing the semiconductor losses, the proposed circuit topology could also improve the power density and efficiency of the power supply system. A computer simulation model using MATLAB/Simulink has been developed to investigate the behavior of the proposed system. Selected simulation results are presented to verify the functionality of the proposed system.

Abstract:

The instrumental control of the charging balance makes it possible to quickly assess the efficiency and technical condition of the components of the vehicle power supply system. Factors have been developed that allow assessing the technical condition of the automobile alternator (efficiency factor) and its operation efficiency at the current combination of load and engine speed. The main parameters of the power supply system were measured using a four-channel analog data logger. Further research will be aimed at identifying the changes in the charging balance of the vehicle in case of failures of the automotive alternator and accumulator starting battery.

Abstract:

The electrical power system is the vital lifeline to most of the control systems on modern automobiles. The following general trends are observed. (a) increased use of electrically actuated systems, (b) increased use of electronic control, (c) increasing requirements for high-integrity power supplies for safety critical systems, (d) increased average electrical power consumption (heating, actuation, control systems), (e) increased electrical demand at engine idle combined with reducing idling speeds, (f) increased interest in higher voltage systems, (g) electrical system problems a major cause of roadside breakdowns. These trends clearly indicate major changes in the requirements of vehicle electrical power supply systems and will demand considerable activity from the vehicle industry in the next decade. An important aim of this paper is to illustrate and promote a systems view of electrical power while considering existing and future problems and opportunities.
