Is a Smaller Battery Good for the Wireless Charging Electric Vehicles?
This paper presents a method for the optimal design of a DWC-EV system, with a specific focus on mass public transit bus system in terms of economics. We first present the method of optimal allocation of the wireless power transmitters called power tracks along the given bus route considering the battery lifetime. The battery degradation model is incorporated to account for a quantitative relationship between power track installation and battery life extension. The model quantitatively predicts battery capacity degradation throughout the battery life span. A numeric case study is conducted with two different cases, one from an actual DWC bus system and the other from the Urban Dynamometer Driving Schedule (UDDS). The preliminary findings provide insight into the relationship between DWC charging from power tracks and the battery's lifetime.
