Laboratory model of charger for electric vehicle based upon the principle of energy transfer by air

Dobroslav KOVÁČ

The wireless energy transfer is known for over hundred years and it is method for transferring electric energy over long distances without the use of any conductive medium.

Because of lack of conductive element, the major disadvantage of such system lies in low efficiency. This paper presents analysis of such system for electric vehicle. The simulation model created in COMSOL Multiphysics is presented. Two coils are placed in close proximity and theoretical efficiency of energy transfer between coils is estimated. Laboratory model of such system for radio controlled (RC) model of car is developed. Experimental measurements are compared with simulation results and necessary steps are summarized that are needed in designing of such system
