A study on modeling of wireless charging system based on fuzzy logic control

Abstract

When the wireless charging system charges the lithium battery, in order to reduce the size of the receiver. With the increase of the charging power of the lithium battery, the charging strategy of the lithium battery should be changed accordingly, so as to improve the performance of the lithium battery. According to the characteristics of the wireless charging system and the charging strategy of the lithium battery, the whole system is dynamically adjusted based on the fuzzy logic control principle, so that the system can provide the required charging power for the lithium battery under different charging strategies. In this paper, the circuit model of the wireless charging system and the equivalent model of the lithium battery are established respectively, and the fuzzy logic control strategy is proposed. Finally, the accuracy of the control strategy is verified by simulation, which provides a reference for the dynamic adaptive adjustment of the wireless charging system.
