Abstract

Aiming at the applications in wireless smart homes, a wireless charging system based on LCL topology is designed. Moreover, the constant-current (CC) output of the system is realized according to the charging characteristics of lithium batteries. On this basis, a charging strategy is proposed, which is able to identify load characteristics and take corresponding actions after the access of loads in smart homes to the system, and can guarantee the safety of the loads in power supply process. Finally, an experimental prototype of the system was established to wirelessly charge the lithium battery with a nominal voltage of 7.4 V and verify the validity of the proposed charging strategy for protecting the system when illegal loads were connected in the system.
