Abstract

Increasing the number of electrical vehicles determine an increasing of electrical vehicle chargers number too. The best situation is reach when the zero emission vehicles are charged with electrical energy produced by solar panels or another green energy. This paper presents a solar electric vehicle charger system with energy storage capabilities. The system should be considered as a combination of three systems: solar energy production system, energy storage system and electric vehicle charger system. One of the novelty of the system is that for energy storage is used a 2nd life Nissan Leaf electric vehicle battery. The paper gives information about, simulation and measurement of the annual solar energy production of the system, measurements results of the currents, voltages and powers of the system, and a distribution of the maximum daily energy production.

Analytical software has been developed based on the Costello-theory [1,4], which is able to calculate strains, axial force and twisting moment in the seven-wire strand under tensile load. The FEM analysis of this structure also has been carried out, and the results are compared with the experimental data. The results prove good agreement, so sensitivity analyses of some geometrical and material parameters have been performed.

The role of light-emitting diode lamps and radio frequency lighting controls is to reduce the energy consumption. The increase of lighting network complexity determines the increase of EMC noise emission. Being familiar with measurement systems is important for making correct measurement and for understanding the results of the measurement. Correct interpretation of measurement results is the first step in choosing the best suppression method. The suppression method depends on the common mode and the differential mode of noise type and on the frequency of signal noise.
