This paper examines the relationship between legal policy and the Electric Vehicle market in countries from around the world. As climate change has become an increasingly more important issue in modern society, heavy emphasis has been placed on environmentally conscious alternatives to many things used in daily life. Transportation, one of the largest and most polluting sectors of the economy, has seen many advances towards an eco-friendly future. Electric Vehicles, or EVs, have been lauded as the answer to heavily-polluting Internal Combustion Engines (ICE) by governments around the world. They have dumped large amounts of money in the form of tax breaks and subsidies into the EV sector, but it is unclear if that is really having an effect on the market. This study finds no correlation between the amount of money a government is offering to subsidize the purchase of EVs and the EV market share of the country. While EV law structure varies heavily between countries, the general contribution to the sector by governments is largely the same around the world.

The increasingly restrictive standards related to exhaust emissions from cars make difficult the development of internal combustion engines. The activities undertaken in the design of internal combustion engines are mainly based on downsizing, e.g decreasing the engines displacement. The main direction in the development of vehicle propulsion is to reduce carbon dioxide emissions. It is expected to reduce CO2 emissions in 2020 to reach 95 g/km. Electric vehicles achieve low noise levels and do not emitted a burn, and thus, their use leads to a reduction in the amount of toxic exhaust gases in the air. The aspect of reducing emissions of harmful exhaust compounds and activities focusing on downsizing on the market of combustion engine cars leads to a significant increase the number of electric vehicles. In 2018 around 95 million motor vehicles were registered in the world, of which around 12 million in the European Union and 273 thousand in Poland. The number of electric vehicles among all sold is around 5.5%. Every year new, more technologically advanced models appear on the electric vehicle market. In 2018, the most popular model was the Nissan LEAF and the BAIC EC-Series. A large number of Renault ZOE have also been sold. In article analyzed different models of electric vehicle, which are available on market and presented the characteristics based on e.g. price per 100 kilometers, range for every model or charging time.

Dynamic Emulation

Current researches on electric vehicles are focusing on the environment and energy aspects. However, electric motors also have much better control performance than the internal combustion engines. Electric vehicles could not only be “cleaner” and “more energy efficient”, but also become “safer” with “better driving performance”. In this paper, a discrete elasto-plastic friction model is proposed for a dynamic emulation of tire/road friction for developing control systems of electric vehicles. The friction model can capture the transient behavior of the friction force during braking and acceleration, therefore the model-based emulation could enable more reliable verifications for various electric vehicle control methods.

Many pollution-related issues are raising due to the usage of conventional internal combustion engines (ICEs) vehicles. Electric Vehicles/ Hybrid electric vehicles (EVs/HEVs) are the finest solutions to overcome those problems associated with ICE-based vehicles. The EVs are introduced with a signal energy source (SES), which is not a successful attempt, especially during transient vehicles, driving, etc. Multiple energy sources (MES) EVs are introduced to attain better performance than the SES vehicles, which is obtained by combining two sources like battery/fuel cells, ultracapacitor. In this contest, energy management (EMNG) plays a vital role in sharing the load to the sources as per the EVs requirement. In the case of MES-based EVs, the controller always plays a significant role in the related EMNG system because it is the key factor in improving vehicle efficiency. In this article, a study has mainly been done related to several conventional, intelligent controllers and control algorithms to do the proper EMNG between sources present in the EV.

Abstract Byproducts of fossil fuel combustion contribute to negative changes in the global climate. Specifically, emissions from automobiles are a major source of greenhouse gas pollution. Efforts to minimize these harmful emissions have led to the development and sustained improvement of hybrid drivetrains in automobiles. Despite many advancements, however, hybrid systems still face substantial challenges which bear on their practicality, performance, and competitive disadvantage in view of the low cost of today’s traditional internal combustion engines. These imperfections notwithstanding, hybrid electric vehicles have the potential to play significant roles in the future as cleaner transportation solutions. Actualization of this potential will depend on the ability of hybrid-electric vehicles to minimize their disadvantages while increasing their positive features relative to traditional combustion engines. This research investigates current hybrid electric architectures in automobiles with the aim of suggesting an alternative, more efficient hybrid configuration that utilizes current technology. This is completed by utilizing an iterative design process to compare how various components of existing hybrids can be combined and/or improved to develop a single, efficient and cohesive system that performs comparably to or surpasses existing ones in fuel efficiency and low emissions in all driving conditions. A critical and comparative analysis is provided based on current hybrid-electric vehicle architectures as well as a plausible alternative.
