Electric Cars as a Future Energy Accumulation System

The aim of this study is to identify new opportunities for energy supply in Poland and in the world, on the basis of electric cars (EC). It was assumed that being connected to the local power systems, they can accumulate significant amounts of energy and effectively prevent from occurrence of electric power deficit. To achieve the above mentioned goals the problem has been formulated in the form of the following questions: what are the conditions and technical potentials for energy use in transport? What needs to be done in order to achieve the assumed satisfactory level of energy supply involving improving power availability in the Polish National Power System (NPS) and prosumer use of electric cars, for example in Poland? What are the examples of implementation of different sources of electricity into the electric power system? The innovation involves using mobile (car) prosumer electric power (Ee-Mobile) for battery charging, for example, they can use power from non-renewable sources of energy (RES) and/or renewable energy sources (RES). Environmental compatibility of various ways and means (according to their own evaluation methodologies), as technical solutions for charging and discharging rechargeable batteries for the car own purposes and for the purposes of the local energy systems in case of a deficit, was defined.
