Feasibility Study for Dynamic Wireless Power Transfer in Simulation with Big Data Focusing on Battery Capacity Requirement of Electric Vehicles

Dynamic Wireless Power Transfer (DWPT) has been proposed to solve the problems of electric vehicles. The requirements of DWPT are changed by not only the specifications of vehicles, but also the driving style of each driver. This paper presents the battery capacity requirements of DWPT by analyzing big data obtained from customers' vehicles. The proposed analysis method shows 99 % of vehicles can drive infinitely if they have at least 7.88 kWh battery when the output of the in-motion charging is set to Pin, WPT = 40 kW.
