Social background

In the future, electric vehicles (EVs) are expected to spread rapidly toward the realization of carbon neutrality. However, conventional charging methods for EVs have the problem of long charging time. To address this problem, a new charging method that realizes much faster charging time than that of the conventional charging methods is needed.
 

Purposes of the activities

To commercialize a non-contact power supply system capable of quick charging, we aim to establish the basic technology for the world’s first non-contact power supply system for EVs using a full-scale superconducting coil.
 

Overview of activities

When AC current flows in a superconducting coil, the problem of AC loss arises. To solve this problem, we aim to develop a low-loss superconducting coil suitable for a non-contact power supply system for EVs.
 

Expected effects

The realization of a non-contact power supply system for EVs capable of ultra-fast charging would spur the spread of EVs and reduce CO2 emissions, thereby contributing greatly to the realization of carbon neutrality.
