Modular On Road AGV Wireless Charging Systems Via Interoperable Power Adjustment
This paper proposes a modular on road wireless power transfer system with interoperable power adjustment mechanism. The paper is anticipated to enhance the capability of on road charging during the movement of automated guided vehicles (AGV) by which the traveling mileage is increased, while the battery volume is decreased. The system design includes an interoperable power adjustment technique based on the detected impedance, and the moving position of AGV can be, hence, comprehended so as to facilitate the adjustment of the output power from each transmission module in a more flexible way. Through the investigation of on road charging efficiency, all of coil magnetic analysis, misalignment charging evaluation, system stress simulation, and resonant characteristics investigation are performed. Experimental results gained from software simulation and hardware realization are beneficial for AGV charging applications.
