Influence of Coil Characteristics on Charging Efficiency in Electric Bicycle Wireless Charging System
Explore the characteristics of wired and wireless electric bicycle charging under the environment of energy saving and emission reduction.This paper introduces the principle of electric bicycle wireless charging and analyzes the influence of coil characteristics on wireless charging system.Based on COMSOL Multiphysics software platform,the wireless charging system was simulated,and some characteristics of the coils in the system were analyzed.The simulation system focuses on the shape,axial distance and horizontal migration characteristics of the coil,takes the coil mutual inductance value as the starting point for simulation analysis,and collates the data into charts to intuitively show the influence of coil characteristics on the charging efficiency of the wireless charging system.The system is simulated according to the possible situations in the actual application scenarios.The simulation results show that the coil characteristics in the wireless charging system have an extremely important impact on the power transmission efficiency of the entire system.Therefore,optimizing the coil design in the wireless charging system can effectively improve the wireless charging efficiency.
