Opis:
Extensive environmental protection activities include the promotion of alternative drive systems for motor vehicles. An important role in this field is played by hybrid vehicles, with their low operation costs being a strong marketing argument. Can such economies be conducive to the intensity of use of hybrid vehicles compared with vehicles with conventional drive systems? To answer this question, the intensity of use of hybrid vehicles was observed in a few different countries. The attention was focused on the occurrence of extreme (very low and very high) mileage values within comparable vehicle groups. The survey carried out has revealed distinct differences in the intensity of use of hybrid vehicles compared with motor vehicles with conventional drive systems (IC). The average mileage values for hybrid vehicles are higher than those recorded for conventional ones during the same period, but this difference can only be seen in the initial period of vehicle use, rapidly decreasing with vehicle operation years. The share of vehicles with extreme mileage values recorded during the period under observation, presented in the paper in several ways, declines with the years of vehicle use. In spite of that, however, the percentage of vehicles with extreme mileage values is high in HVs group against IC.

Opis:
Many large cities in Europe are currently trying to reduce the amount of harmful substances for the residents. Road transport is also an important source of air pollution. One way to reduce pollutant production is to operate more environmentally friendly vehicles. The paper analyses data obtained during practical tests of a hybrid vehicle in urban traffic. The individual components of the exhaust gases are calculated in g/km and they are compared with the values for conventional vehicle propulsion. The data was obtained through a commercially available exhaust gas analyzer and a calculated amount of emissions produced from available data from the engine control unit. The results shown that using of this type of propulsion has its importance in cities with increased air pollution. During urban operation, the hybrid-powered vehicle was powered by an electric engine up to 67.70% (75.40% of the time). As a result of operating such a vehicle in the city, emissions of CO2, HC and NOx are significantly lower.

Opis:
With the rapid growth of schemes and initiatives to promote e-mobility and numerous measures taken to ensure its quick and effective implementation, there is a wide range of technological and non-technological problems, especially organisational, economic, legal and social in nature, that have to be handled by national and local governments all over the world. This article addresses some of the technological and organisational challenges for electromobility. The key technology-related issues to be coped with are the need for longer ranges of electric vehicles (EVs), shorter charging times and smart power grids (because of a higher demand for electrical energy). Another important problem to be solved urgently is the high battery weight, affecting the vehicle dynamics. Because of the excessive weight of the battery pack, there is a risk of its displacement during a crash, which may jeopardize the safety on the road. The next big concern, also associated with safety, is protection against electrical and fire hazards in the event of a collision. The most important of all the organisational challenges related to EVs is the necessity to create networks of charging stations. Their insufficient number and unsatisfactory distribution are strong barriers hampering the development of e-mobility. The organisational measures also include privileges such as access to bus lanes, already offered in some countries. Finally, there is the need to urgently train a large number of electricians to test and maintain EVs, the need to create a recycling system for used EV batteries, and the need to deal with the organisational aspects of the development of smart power grids.

Opis:
The first autonomous car was developed in the 1980s, but it wasn't until the early 2010s that the technology began to gain significant attention and investment. In 2010, Google began testing self-driving cars on public roads, and since then, many other companies have joined the race to develop fully autonomous vehicles. Hybrid PVT (Photovoltaic Thermal) heat exchangers cooled with mini-channels find application in autonomous vehicles as a solution that enables efficient cooling of the vehicle's electronics and batteries. The solution involves using photovoltaic panels to generate electricity and removing the heat produced during the process using mini-channels is removed by mini-channels. Hybrid PVT heat exchangers cooled with mini-channels can help maintain appropriate temperatures inside autonomous vehicles that generate large amounts of heat from electronic systems and sensors. The setup can improve the performance and reliability of autonomous systems, increase energy efficiency, and reduce energy demands. The experimental setup includes two parallel mini-channel systems separated by a smooth copper plate. The study aims to determine local heat-transfer coefficients, with a cooled solar cell efficiency range of 10% to 14% compared to other research. The cooled PV temperature range achieved was from 19.6 to 22.4 degrees Celsius, which is favorable for photovoltaic panels' operation under approximate light intensity for Poland's latitude. Heat-transfer from hot surfaces to cold fluids is analyzed during single-phase convection using two calculation methods: one-dimensional and numerical simulations using Simcenter STAR CCM+. Cooling photovoltaic modules is critical for the photovoltaic and autonomous vehicle systems sector, making this research significant both theoretically and practically. The research and methods presented in the article on mini-channel cooling of photovoltaic systems and autonomous vehicle systems are innovative at a global scale, and are crucial for further development of sustainable energy systems and reduction of greenhouse gas emissions.
