Thermal Modeling of an ERS during Dynamic Charging

A charging system which allows vehicles to charge while moving makes it possible to both reduce onboard battery capacity and alleviate range anxiety. An Electric Road System (ERS) is a piece of charging equipment developed to allow charging of moving vehicles. At high charging power levels, the heat generated in the ERS needs to be managed in order to prevent overheating of the equipment. This paper proposes a thermal model to simulate the temperature distribution inside the investigated ERS. This thermal model can then be used to determine the size of the system and to determine a proper charging strategy.
