Opis:
The article includes experimental investigations of electricity consumption over a distance of 30,000 km by a small city electric vehicle. During that time period, the vehicle was charged in most cases from a photovoltaic carport with a peak power of 3 kWp. The analyses include vehicle mileage and the number of times the battery has been charged during 5 years of operation. In addition, the amount of energy generated by the photovoltaic carport was also measured. During the entire research period, the small electric vehicle was charged with State of Charge (SoC) 50% almost 900 times. Then, an analysis was performed to determine the adequacy of the carport peak power selection for the energy needs of the electric vehicle. Based on an analysis of the amount of electricity produced by the carport during the season of use of the electric vehicle, it may be concluded that the average production of electricity in the selected period is about 2 times higher than that required to fully charge the electric vehicle (100% of SoC). Therefore, when designing the carport, the power required to charge the electric vehicle was correctly forecast.

Opis:
Electromobility is associated with the ever faster development and introduction of new electric vehicles to the market. They use an electric motor to drive the wheels of the vehicle and the necessary electricity is stored in traction batteries. Electric vehicles have a different construction than traditional vehicles i.e. those powered by internal combustion engines. For this reason, the manner of use, maintenance and service are different. Familiarization with selected operational issues of electric vehicles positively affects the reliability of their use as well as safety and comfort of driving. An important component of electric vehicles is the traction battery. Its proper operation influences the long-term preservation of the initial energy capacity and, thus, the range of the vehicle. The article presents tests of the state of traction batteries of a small electrically powered city vehicle. The vehicle, the batteries and the diagnostic devices used to assess the condition of the battery are described in detail. Based on the literature analysis and the observation of market trends, a fast and effective method of assessment of the technical condition of batteries in electric vehicles is proposed. The method has been tested on the selected vehicle. The technical condition of the battery in the vehicle was assessed after 4.5 years of operation and 30,000 km mileage.

Opis:
The EU transport policy is to implement a plan aimed at a significant reduction of the CO2 emission, to be phased over the years 2020-2030-2050. Therefore, restrictions are to be gradually imposed on the use of vehicles with internal combustion (IC) engines, to eliminate such vehicles from urban traffic by 2050. Instead, the vehicles with alternative, low-emission drive systems will be promoted. At present, very high prices of electrochemical traction batteries have a significant share in the vehicle purchase price and electric vehicles are much more expensive than vehicles with conventional drive systems. The high purchase prices are compensated by low electric energy costs in comparison with the costs of hydrocarbon fuels. The present-day battery technologies should be considered an interim stage and should not be treated as a target, because they may turn out within a few years to be cost-consuming and obsolete solutions. On the other hand, electric traction motors have been built, developed, and used for many years and the risk of their failure is lower than the risk of a battery failure. The battery recharging process always involves the necessity of providing adequate infrastructure of a power supply network. Electric vehicles, especially their batteries and battery charging systems, are still at the development stage, without a crystallized vision of target solutions. Another problem is the lack of infrastructure and standardization. In spite of this, electrical drives (including those with hydrogen fuelling), as being characterized by zero emissions, may be expected to become in the long term a target and predominating solution.
Celem polityki transportowej UE jest plan znacznej redukcji emisji CO2 rozłożonej na lata 2020-2030-2050. Stopniowo wprowadzane będą obostrzenia dla pojazdów z napędem spalinowym, aż do całkowitego ich wyeliminowania z ruchu miejskiego do 2050 r. Pojazdy o napędach alternatywnych, niskoemisyjnych będą z kolei promowane. Wysokie ceny trakcyjnych baterii elektrochemicznych sprawiają, że stanowią one znaczny udział w cenie pojazdu, a pojazdy elektryczne są znacznie droższe od pojazdów z napędem konwencjonalnym. Wysokie ceny zakupu są rekompensowane niskimi kosztami energii elektrycznej w stosunku do paliw węglowodorowych. Obecne technologie baterii są technologiami przejściowymi i nie należy ich traktować, jako docelowe, a w ciągu kilku lat mogą okazać się rozwiązaniami drogimi i przestarzałymi. Z kolei trakcyjne silniki elektryczne są budowane, rozwijane i eksploatowane od wielu lat i ryzyko związane z ich awarią jest niższe niż w przypadku baterii. Z procesem ładowania baterii zawsze wiąże się konieczność zapewnienia odpowiedniej infrastruktury sieci energetycznej. Pojazdy elektryczne, a szczególnie baterie i systemy ładowania, są ciągle w fazie rozwoju, jeszcze bez wykrystalizowanej wizji docelowych rozwiązań. Problemem jest też brak infrastruktury i standaryzacji. Mimo to można przypuszczać, że w długim terminie napęd elektryczny (w tym wodorowy), jako zero-emisyjny, będzie napędem docelowym i dominującym.

Opis:
The article presents a method of a photovoltaic system power selecting for proper electric vehicle. At the beginning, the characteristics of the electric vehicle itself and its traction batteries were made in order to determine the method of its charging. In the presented studies, measurement data from the operation of real photovoltaic systems was recorded and processed. The algorithm used includes examining the energy consumption profile of the owner's residential building. The combined demand for electricity of the electric vehicle and the building made it possible to determine the planned photovoltaic system. The authors presented three possibilities of its location. It can be installed on the roof of the building, on the ground next to the building or on the carport under which an electric vehicle can be parked. Finally, the Metalog family of probability distributions was used to analytically validate the power choice of the photovoltaic system. The authors have developed an algorithm using human and artificial intelligence that helps to properly select the power of the photovoltaic system for the vehicle.

Opis:
The technology of photovoltaic solar cells can be combined with the technology of electric vehicles. During charging electric vehicles with Renewable Energy Sources (RES) as well as during their use to the atmosphere are not emitted any pollutions. The article presents a carport designed for charging electric vehicle. Paper analyzed the power course generated by the photovoltaic system in different weather conditions. As a result of the comparison with the current demands of the electric vehicle battery during the charging process the optimal way of battery charging process was discussed. Later in the article presents logistics research on charging battery of an urban vehicle used frequently by catering companies to distribute products. The authors’ aim was to determine the actual range of the small electric vehicle on a single charge, as well as to statistically compile driving parameters in conditions of urban traffic in Lublin. The process of using such a vehicle has been analyzed, including the necessary battery charging. On the basis of the tests results a set of recommendations for small electric cars users was made in order to help increase the range of the vehicles in traffic and lengthen battery life.
