Abstract: This paper introduces the electric car remote monitoring, calibration test and diagnosis system, which choose Changchun Unicom WCDMA as a medium of communication and hardware-in-loop system of Jilin University as test tools. Collecting operation data of the hardware-in-loop system through the 3g network, the data that verify the remote monitoring and diagnosis function. The marked ECU, which is Mattoon platform, sends commands to vehicle information terminal through the remote calibration software and realizes the function of the remote calibration in real-time monitoring mode.

Abstract: As the electric vehicles (EVs) such as hybrid, battery, and fuel cell cars have become common in market, there is an opportunity to apply vehicle-to-grid (V2G) power. This article introduces the concept of V2G and uses equations to calculate the capacity for grid power from defined electric drive vehicles. Further this paper evaluates the revenue and costs for V2G mode from selling electricity into market. The results show that developing V2G mode provides electric vehicles owners and electric utilities additional revenue, stability and reliability of the electric grid, lower-cost storage for intermittent power resources.

Abstract: A novel scheme of charging-discharging-storage integrated station is put forward. In order to control energy/power flowing in the integrated station effectively, a new definition of general energy is fully discussed and its periodic characteristic is analyzed. General energy includes three parts: general energy of battery supply system, general energy of battery echelon utilization system and general energy of EVs, all of which is almost periodic. After analyzing steady operation curves of the three parts of general energy, their interrelation is discussed. On this basis, a periodic control strategy for general energy is proposed. Taking typical bus operation in Shanghai as a case, general energy curves of battery systems and EVs are described and analyzed under periodic control strategy, which obviously shows that the integrated station can maintain stable and economic operation by periodic control of general energy flowing in the integrated station.

Abstract: Compared to reactive power/voltage index and standard operation procedure (SOP) of power system, the reactive power/voltage index of charging-discharging-storage integrated station is defined, which includes voltage margin and voltage adjustable capability of integrated station ((ISVM & ISVAC). And then the reactive power compensation control strategy of integrated station is put forward and proved to be lossless in power. According to the reactive power regulation characteristic, a reasonable reactive power distribution between shunt integrated stations can be realized by the reactive power/voltage optimization algorithm. And the synthesis optimization can be achieved when AVC applied into integrated station, which will bring value-added benefit to power quality and greatly improve the grid reliability.

Abstract: The aim of this study is to understand the consumer in the country of Malaysia which is one of the most developed countries in Southeast Asia. The study is being carried out to explore the consumer buying behavior in hybrid vehicle (HV). The objective of this study is to study which factors affect consumers hybrid vehicle buying decision. In addition, the study also in-depth analyzed whether there is any relationship between influencing factors and demographic factors such as gender, income, education and age. SPSS version 20.0 has been used for analysis the data information. 500 respondents will be selected to fill the questionnaire. The finding of this study provided empirical results to academician and vehicle producer in the field of green vehicle buying behavior in Malaysia.

Abstract: For accurately studying the performance of LiFePO₄ battery group, this paper conducted CC and HPPC cycle charge/discharge performance tests of LiFePO₄ battery, and designed an improved equivalent circuit model based on the data analysis. Compared to the traditional model, the model considered the impact of the hysteresis voltage, had more accurate corresponding relationship between SOC and balance voltage, obtained a more realistic overpotential property by contrasting different order models. Estimated model parameters, modeling in Matlab / Simulink environment and simulation in the UDDS condition, verified the accuracy and feasibility of the designed model by comparing with experimental data.

Abstract: The commercial mode of electric vehicles (EV) is helpful for the development of electric vehicle industry, which is also an effective way of forming the electric vehicle consuming market quickly. To research and explore the relationship of main participant bodies in the electric vehicle commercial market is an important research topic. Therefore, this paper, based on the proposed hierarchical structure of the electric vehicle commercial mode, analyzes the roles and functions of the chief market participant bodies from three levels. Finally, the paper discusses some future research directions.

Abstract: In order to study the influence of environment which the hybrid electric vehicle made, used the simulation software advisor to the prevailing two hybrid cars: Toyota and Honda Prius snd insight engine, motor and battery of the matching calculation. And made a comparison with conventional cars. Compared to traditional cars ,the hybrid cars have obvious advantages in environmental protection.

Abstract: The uncertainty of driving area, the power load control of charging facility and charging rates make electric vehicles(EVs) facing different charging facilities, so it is necessary to control charging in the charging process. An adaptive electric vehicle charging control strategy was proposed in this paper. The strategy uses wifi for communication, communicating with charging pile through wifi, charging facilities and electric vehicles can exchange parameters to achieve adaptive control of the charging process. And experiment was conducted for verification.

Abstract: Electric vehicle charging, since the uncertainty of the travel area, and the different load control of the charging infrastructure grid and the different rates over time, needs to face different charging devices and use different charging parameters. The situation is very complex, so electric vehicle needs to be adaptive control for various situations in the charging process. Aiming at the communication between electric vehicle and power grid, there is no relevant national standards promulgated. After comparing several possible communication modes, I choose to use the PLC communication, and SDP for charging device to automatically obtain and connections. Charging parameter passing through the communication between the electric vehicle and charging facilities, in order to realize the adaptive control of electric vehicle charging.
