Regenerative Energy Control Technology of Charging Vehicles in Electric Road System 2024-01-2171

This Electric Road System was devised that would provide electric power to EVs directly from the infrastructure so that EVs could undergo intermittent charging while driving. This system is a conductive dynamic charging system that operates from the side of the vehicle (roadside), and research has been underway on the application of this approach to passenger cars and race cars. This paper focused on resolving issues with freight vehicles, which account for most of the CO2 emissions in the transportation sector. This Electric Road System that operates by contact from the roadside was applied to heavy-duty trucks, which have been considered a challenge to convert to EVs, and at the same time the infrastructure technology was also expanded and evolved. And verification tests using actual vehicles were conducted for regenerative energy absorption control of a charging vehicle while driving. The results confirmed that this control system appropriately controls the distribution of power received from the infrastructure and the regenerative energy of the vehicle’s drive motor. This paper will present results from verification with actual vehicles, including control of regenerative energy absorption during dynamic charging. Going forward, further studies will be conducted for social implementation with the goal of early practical application of this system.
