Contactless Battery Charging for EV/HEV

Abstract

Wireless energy transmission is currently an important concern, con-sidering its multiple applications in modern electrical engineering. There are different topologies in the scientific literature for near field (magnetic or elec-tric) 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 solu-tion for the implementation of driverless vehicles in the near future. The se-lected constructive solutions were experimentally checked on a test bench fitted with the necessary electrical and electronic facilities to characterize the compo-nents 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.
