    Opis:
    The paper is devoted to the construction and design solutions of the power supply and drive systems of a prototype, lightweight LHD (Load-Haul-Dump) loader with an innovative "in-wheel drive" transmission system. The loader is a Battery Electric Vehicle (BEV) with replaceable energy storage. It is intended for use in underground mines with no explosion hazard, especially in metal ore mines. The developed model contains four independent, electric drive systems installed in the road wheels. The paper presents the results of simulation tests, which enabled estimating the required driving power and electricity demand in various regimes and working conditions of the loader. The results of the calculations were used to determine the parameters of the drive system components and the battery capacity. Challenges and problems faced by constructors of BEV LHD loaders with an in-wheel drive have been pointed out.

    Opis:
    In the article were compared the vehicles (by pairing) the vehicles on the basis of selected criteria considering vehicles’: weight, length, wheel width, maximum output and acceleration time. The article was carried out by analysing the available source materials and specific energy mix based on coal. The emission of air pollutants (exhaustive) was estimated using the mathematical calculation. In order to carry out the analysis, the data provided by the manufacturers of the considered cars were used, concerning fuel consumption by the cars equipped with the internal combustion engines or electricity consumption in the case of cars with equipped with electric motors. The air pollutants that were taken into consideration: carbon monoxide, nitrogen oxides, sulphur dioxide, carbon dioxide, and total particulate matter. Apart from the exhaustive emissions, the total particular matter emissions from the tyre and brake wear and road abrasion is also included. The pollutant emission was estimated on the basis of emission factors using the average mileage characterizing for driving in European conditions.

    Opis:
    The way of directive of the European Parliament and the Council in 2014/94 on October 22nd 2014 in the case of infrastructure development of alternative fuels which was specifically concerned with calls to reduce oil dependence on transport in European countries was imposed due to the necessity to formulate specific provisions in individual nations in the Union. In correlation to this, on the day of 11th January 2018 the act on electromobility and alternative fuels was passed, which came to be on the day of 1st September 2018 with changes implemented later on. The regulations mentioned above oblige public transport to partially replace their diesel engine-based rolling stock and introducing changes to alternative fuels (compressed hydrogen in gaseous form belongs to such fuels). Support systems in Poland are an important element in the implementation of modern and ecological technologies. Very often those solutions are much more expensive compared to the ones used so far. The financing provided by them enables the realization of such projects in our environment. In this work, the idea of emission-free public transport operating on the basis of electric vehicles (Battery Electric Vehicles) as well as hydrogen (Fuel Cell Vehicles) will be presented. Both of these variants will be compared and their working principle are going to be shown. The analysis of support systems for the development of emission-free public transport on a European, national and regional level will also be presented. All collected information will form a compendium of information essential to implementing the public transport project in Polish conditions.

    Opis:
    Due to limited resources of fossil fuels and overproduction of greenhouse gases, a need for alternative means for vehicle communication appeared. Because of that hybrid electric vehicles, as well as battery electric vehicles, were proposed to replace some of conventional vehicles based on internal combustion engine [3]. To their advantages over conventional cars belong environmental friendliness and better performance (in case of hybrid electric vehicles), but they also suffer from greater purchase costs and limited range (in case of most battery electric vehicles) [4, 6]. Presented work briefly characterizes four types of vehicles equipped with electric motor (mild hybrid, full hybrid, plug-in hybrid and battery electric vehicles) along with generalised presentation of their battery requirements [4, 6]. Further in this work, the lithium-ion (Li-ion) battery working principle was explained, along with characterisation of its limitations due to its design and requirements for inactive components e.g. 4-fold drop in specific capacity and energy density while moving from pure electrode material level to battery level [20]. Next, present Li-ion active components, such as LiCoO2, LiMnO2 and LiFePO4 cathodes and graphite anode along with their capacities and energy densities as well as other characteristic regarding (e.g. environmental friendliness, safety and cost) are shown. Moreover electrode materials e.g. nanocomposite anodes and cathodes, multi-electron cathodes (e.g. Li2MnSiO4), as well as Li-metal and Li4Ti5O12 anodes, with their advantages and disadvantages were described [15, 20]. Presented article was summarized by gathered opinions of battery electric vehicles users, who share their experience regarding their electric cars in a survey. One can tell that they are fairly satisfied with their purchase and that improvement in range of battery electric vehicles along with predictable government policy regarding electrification of cars are the most important factors when considering purchase of electric vehicle [36].
