Ultra-Fast Wireless Power Transfer System for EV Fast Charging

Project description

Enabling zero-emission public transportation without impairing the normal operation of buses can be facilitated by ultra-fast charging converters based on wireless power transfer technology. Herein, the battery charger can be installed on the route, more specifically in bus-stops, for allowing opportunity capacity enhancement of the on-board batteries during 3 to 6 minutes while passengers are being hop-in/-off. 

High efficient and ultra-high power chargers delivering a power close to the maximal allowed by the battery banks are necessary for the effectiveness of this system. Particularly, for the wireless power technology there is no need of mechanical contact between the Electric-Buses and the charging infrastructure, thus a more reliable and effective use of the installed power can be achieved. 

The PhD candidate will investigate and propose advanced power electronics and components suited for 200kW Fast EV charging infrastructures based on wireless power transfer. All the researched systems and components will be optimized using multi-objective design optimization strategies in terms of efficiency, power transfer capability, life time estimation, cost/ total cost of ownership and reliability. These solutions will be sought to achieve a 20% smaller size, reaching peak efficiency of > 97%, which is 2% higher than conventional wireless power systems.
