Summary

Electric vehicles (EVs) are crucial for the transition to low-carbon mobility and achieving carbon neutrality. However, the limited driving range is a barrier to its adoption. To solve this obstacle, one approach involves equipping electric vehicles with higher capacity batteries. This approach not only requires longer charging times, but also leads to higher vehicle prices and more CO₂ generation for its production. Therefore, innovative approaches are essential to achieving true carbon neutrality across the entire mobility lifecycle.

Dynamic Wireless Power Transfer (DWPT) is an emerging solution that directly supplies electric power to moving EVs via coils embedded in the road. By delivering power during driving, the waiting time for charging can be eliminated and the number of batteries installed in EVs can be greatly reduced. To expedite the social implementation of DWPT, DENSO CORPORATION (hereinafter, referred to as "DENSO") has developed an onboard system that delivers 20 kW of power. This system was installed in an EV and the vehicle achieved 50 hours of continuous driving without charging.
