Research Papers on Electric Vehicles

Research Papers on Electric Vehicles:- An electric vehicle is a vehicle that is driven by an electric motor which draws its current either from storage batteries or from overhead cables. A fuel-cell car is an electric vehicle that makes its own electricity. All-electric vehicles (EVs) have an electric motor instead of an internal combustion engine. The vehicle uses a large traction battery pack to power the electric motor and must be plugged into a charging station or wall outlet to charge.

Research Papers on Electric Vehicles

There are the following research papers on electric vehicles:-

1. Integration of Electric Vehicles in the Electric Power System

In this research papers on electric vehicles, presents a conceptual framework to successfully integrate electric vehicles into electric power systems. The proposed framework covers two different domains: the grid technical operation and the electricity markets environment. All the players involved in both these processes, as well as their activities, are described in detail. Additionally, several simulations are presented in order to illustrate the potential impacts/benefits arising from the electric vehicles grid integration under the referred framework, comprising steady-state and dynamic behaviour analysis.1

2. Power Electronics and Motor Drives in Electric, Hybrid Electric, and Plug-In Hybrid Electric Vehicles

With the requirements for reducing emissions and improving fuel economy, automotive companies are developing electric, hybrid electric, and plug-in hybrid electric vehicles. Power electronics is an enabling technology for the development of these environmentally friendlier vehicles and implementing the advanced electrical architectures to meet the demands for increased electric loads. In this paper, a brief review of the current trends and future vehicle strategies and the function of power electronic subsystems are described. The requirements of power electronic components and electric motor drives for the successful development of these vehicles are also presented.2

3. Electric vehicles as a new power source for electric utilities

Electric-drive vehicles, whether fueled by batteries or by liquid or gaseous fuels generating electricity on-board, will have value to electric utilities as power resources. The power capacity of the current internal combustion passenger vehicle fleet is enormous and under-utilized. In the United States, for example, the vehicle fleet has over 10 times the mechanical power of all current U.S. electrical generating plants and is idle over 95% of the day. Electric utilities could use battery vehicles as storage, or fuel cell and hybrid vehicles as a generation. This paper analyzes vehicle battery storage in greatest detail, comparing three electric vehicle configurations over a range of driving requirements and electric utility demand conditions. Even when making unfavorable assumptions about the cost and lifetime of batteries, over a wide range of conditions the value to the utility of tapping vehicle electrical storage exceeds the cost of the two-way hook-up and reduced vehicle battery life. For example, even a currently-available electric vehicle, in a utility with medium value of peak power, could provide power at a net present cost to the vehicle owner of $955 and net present value to the utility of $2370. As an incentive to the vehicle owner, the utility might offer a vehicle purchase subsidy, lower electric rates, or purchase and maintenance of successive vehicle batteries. For a utility tapping vehicle power, the increased storage would provide system benefits such as reliability and lower costs, and would later facilitate large-scale integration of intermittent renewable energy resources. 3

4. Control of hybrid electric vehicles

Global optimization techniques, such as dynamic programming, serve mainly to evaluate the potential fuel economy of a given powertrain configuration. Unless the future driving conditions can be predicted during real-time operation but the results obtained using this noncausal approach establish a benchmark for evaluating the optimality of realizable control strategies. Real-time controllers must be simple in order to be implementable with limited computation and memory resources. Moreover, manual tuning of control parameters should be avoided. This article has analyzed two approaches, namely, feedback controllers and ECMS. Both of these approaches can lead to system behavior that is close to optimal, with feedback controllers based on dynamic programming. Additional challenges stem from the need to apply optimal energy-management controllers to advanced HEV architectures, such as combined and plug-in HEVs, as well as to optimization problems that include performance indices in addition to fuel economy, such as pollutant emissions, driveability, and thermal comfort. 4

5. Analytical Study and Comparison of Solid and Liquid Batteries for Electric Vehicles and Thermal Management Simulation

As the world is growing very fast and the major role player is the technical sector, but when it comes to the Automotive world one cannot forget e-mobility and hence we are also contributing our part in it. We are doing an in-depth study on Solid-state batteries and Liquid state batteries and detailed comparison between them. In the end, we are also doing the thermal management of the batteries using a Simulation tool called the Simulink/Simscape Language Model. E-mobility is still in the developing phase and there are a lot of opportunities available and we targeted the Battery part. In this report we are showing with different facts, proves, calculations and experiments that how solid-state batteries (SSB) are better than currently using liquid state batteries (LSB) because experts believe that the future is of solid-state batteries because of its versatility and many advantages over LSB. We did the comparison between the current electronic vehicles using LSB(Lithium-Ion) and the future vehicles using SSB on various aspects according to our experiment, research and the result we got is outstanding and also found to be the worthy step toward the development of SSB. We also did the thermal management of the battery to increase its on-road efficiency and the result is quite satisfying as we took a small load to check the battery performance and we also gave the comparison of thermal management using two different heat transfer coefficient (5 W/m^2 K and 25 W/m^2 K) and we are able to get better cooling efficiency when we increase the value of heat transfer coefficient. Results, proposed ideas, and the research analysis clearly giving a green signal towards the speedy development of Solid-state batteries and how it overcomes the different disadvantages of Liquid state batteries, whereas Thermal Management Model proposes with several changes give us the in-depth view of the temperature rise and also by changing the heat transfer coefficient one can select a better cooling system for batteries, to operate it in an optimized range of temperature.5

6. Impact of policies on electric vehicle diffusion: An evolutionary game of small world network analysis

To deal with severe energy and environmental problems, the development of electric vehicles has become a global consensus. Faced with the challenges of the future development of electric vehicles in China, the government has been continuously introducing policies promoting electric vehicle industry. This paper uses the NW (Newman and Watts) ‘small world’ network model to explore the dynamic effects of different policies on the diffusion of electric vehicles. The results show that the government’s purchase subsidy policy and restricted travel policy can promote the diffusion rate of automobiles to 60%, and the short-term effect is remarkable. Production subsidies and infrastructure construction policies can promote the diffusion rate of electric vehicles to 70%. Manufacturers’ production subsidies have a greater impact on electric vehicles than consumers’ purchase subsidies. At the same time, low electricity prices and high oil prices will drive the diffusion rate of electric vehicles to 60% and 70% respectively. Finally, combined with the current policy and industry development status, future development prospects are proposed. 6

7. Microsimulation of electric vehicle energy consumption

Energy efficiency is among the main reasons for the increasing popularity of electric vehicles. Even though they are significantly more efficient in comparison to internal combustion powered vehicles, their efficiency varies. In the literature a significant gap between real world energy consumption and declared figures is noted. The paper includes a review of real-world energy consumption studies and measurements and identifies variables that affect it, such as vehicle drivetrain configuration, battery management systems, traffic and environmental conditions. A simplified EV energy consumption model based on the VSP (Vehicle-Specific Power) is presented and evaluated on standard driving cycles, where it provided improvement over existing models due to the use of a charging power limiting function that better describes energy flow during braking energy regeneration. The model was also evaluated under diverse traffic conditions on trajectories obtained from traffic microsimulation using the SUMO (Simulation of Urban Mobility) model. A case study example demonstrating the impact of traffic light control on energy consumption was analysed as energy consumption is affected in a different way in comparison to internal combustion powered vehicles. This was illustrated by carrying out the simulation with and without braking energy regeneration.7
