Honda is preparing to test a wireless charging system that could allow electric vehicles, including heavy-duty trucks, to recharge while driving on highways.
The Japanese automaker has developed technology that transfers electricity from charging equipment installed beneath the road to a receiver mounted on the vehicle. The approach could reduce the need for electric trucks to make frequent stops at charging stations, potentially making long-distance electric freight transport more practical.
Honda developed the system in partnership with construction company Taisei Corporation and road builder Taisei Rotec. Initial testing has focused on whether the equipment embedded beneath roads can withstand the weight and repeated passage of heavy commercial vehicles while maintaining reliable wireless power transmission.
The companies are planning further tests involving power transfer of up to 150 kilowatts, alongside evaluations of durability and electromagnetic-field safety. Honda also plans to participate in a dynamic wireless power-transfer demonstration on the Tateyama Expressway in Japan’s Chiba Prefecture from fiscal 2027.
If successful, the technology could help address one of the biggest challenges facing electric trucks: maintaining sufficient battery range without adding lengthy charging stops to long-distance journeys.
Honda’s highway trials represent another step toward roads that could become part of the charging infrastructure for future electric transportation, potentially changing how commercial EV fleets operate.
