 Abstract 

In General, the charging speed of the batteries for an electric vehicle are relatively longer than the conventional internal combustion engines in case of the slow-charging. Also, the conventional batteries for electric vehicle use EV charging stations or household outlets. This paper proposes a fast charging device for an electric vehicle using LCC resonant converter operating in the ZVS region to solve slow-charging problems. The Li-ion battery is charged in CC-CV mode and proposes an algorithm for compensating for transients that occur when the Li-ion battery is converted to CC-CV mode. The proposed rapid charging device has a shorter charging time than the conventional device. Automatic wireless charging is possible through parking of a fixed parking space so the situations such as charging line disconnection due to human error can be solved.
