Evaluating Reduction of Greenhouse Gas Emission by Magnetic Resonance Coupled Dynamic Wireless Power Transfer of Electric Vehicles Considered with Vehicle Production

Short cruise range is a major issue of electric vehicles. Dynamic wireless power transfer (DWPT) is proposed to solve this problem as it can reduce batteries on electric vehicles. Thus, well-to-wheel is improved by the reduction of drive resistance due to lighter weight of vehicles. Moreover, greenhouse gas emission via the manufacturing of batteries is also reduced. This work evaluates the reduction of lifetime greenhouse gas emission by DWPT from production, generation, and driving by simulation with actual measurement data. It is revealed that compared to conventional electric vehicles, DWPT can not only realize a 14% reduction of greenhouse gas by generation and driving but also 90% reduction via the manufacturing of batteries.
