Review on Reconfigurable Modular Systems in Dual-Frequency Networks for Multi-Device Wireless Charging

Abstract

To begin with, multi-device wireless charging confronts prominent bottlenecks in smart home and mobile office scenarios. These bottlenecks involve electromagnetic cross-coupling interference, insufficient dynamic load adjustment capability, and weak scenario integration performance. To resolve these problems, this review not only synthesizes the research progress related to reconfigurable modular systems based on dual-frequency networks but also probes into the potential optimization directions for such systems in the future. It first sorts out theoretical bases (dual-frequency networks, reconfigurable modules, 5G communication, adaptive power allocation) and clarifies the technical path for cross-coupling suppression. Then it analyzes key technologies (multi-frequency signal isolation) and algorithms (game theory-driven power allocation), and explains the design methodology of the system’s overall architecture, hardware modules, and control units. Finally, based on existing findings, it discusses the system’s advantages: efficiency improvement (cutting multi-device charging efficiency drop from over 30% to <10%), power balance (prioritizing low-battery devices without "power grabbing"), scenario adaptation ("plug-and-charge" in 1 second), and low-latency scheduling (5G millisecond response). Studies show the "dual-frequency network + reconfigurable module + 5G communication" solution breaks traditional limits and meets smart home "seamless charging" needs. It also points out bottlenecks like limited supported devices and poor complex environment adaptation, providing directions for future expansion into smart offices, automotive energy supplementation, etc.
