Abstract
Wireless energy transmission is currently an important concern, considering its multiple applications in modern electrical engineering. There are different topologies in the scientific literature for near field (magnetic or electric) transmission, with emphasis on the efficiency of the process, especially when such systems are used for medium or high power, from 1 to 100 kW, such as required for storage battery charging in electric/hybrid cars. The prototype for wireless charging equipment for storage batteries is presented, designed to allow research and development for optimum constructive solutions for equip-ping actual EV cars. Wireless battery charging is considered as the only solution for the implementation of driverless vehicles in the near future. The selected constructive solutions were experimentally checked on a test bench fitted with the necessary electrical and electronic facilities to characterize the components and the constructive unit. At the same time, the prototype with a power transfer output of 2 kW will be used to carry out the first wireless charging station at the Automotive Engineering Research Centre of the University of Pitesti.
