Praca dotyczy zagadnienia ładowania baterii (akumulatorów) pojazdów elektrycznych z wykorzystaniem technologii bezprzewodowej. W artykule scharakteryzowano układy stosowane do bezprzewodowego zasilania odbiorników. W przeprowadzonych analizach skoncentrowano się na efektywności poszczególnych rozwiązań. Przeanalizowano, na przykładzie wybranego pojazdu, straty energii związane z zastosowaniem indukcyjnej metody ładowania. Oszacowano roczne straty energii. Wykazano, że nawet nieznaczne zwiększenie sprawności przesyłu energii drogą bezprzewodową, może w ujęciu globalnym (z punktu widzenia systemu energetycznego) istotnie ograniczyć straty energii.

The paper deals with the issue related to the charging of batteries of electric vehicles using the wireless technology. The article presents the circuits used for the wireless powering of receivers. The main focus of the conducted analyses was the effectiveness of the respective solutions. Based on the example of a selected vehicle, the energy losses related to the application of the inductive charging method were analysed. The annual energy losses were estimated. On top of this, it was demonstrated that even an insignificant increase in the efficiency of the wireless energy transfer may globally limit the energy losses (from the point of view of the power system) to a significant extent.

The paper presents the idea behind the implementation of a system designed to monitor biomedical parameters and the subject's behaviour on the basis of the architecture of measurement modules located on the body. The system was developed as a result of market launch of new generations of electronic devices combining high functionality, small size and low power consumption. The paper presents the elements of the system called BioSip, along with hardware solutions selected for the objectives to be accomplished, i.e. providing communication between system elements that would be efficient and resistant to artefacts, extending the time of operation for battery power supply, as well as ensuring a satisfactory level of reliability and ease of use.

Using inductive powered batteries in public transportation vehicles delivers a lot of benefits. The most important advantage is contribution to environmental protection by reducing exhaust emission. The special construction of inductive buses, results more quite engine running, so among benefits there are also noise limitations (about 7dB comparing with diesel engines). Although the cost of inductive buses is almost twice bigger, the whole investment returns fourfold faster by low exploitation cost of such vehicles. Unfortunately implementing this technology requires road infrastructure adjustments, such as mounting inductive charging station into the road surface. It is worth mentioning that nowadays, when pro-ecological projects play a key role in transportation development strategies, the inductive vehicles can be an answer to all of necessary demands.
