摘要
In public environments where LC wireless charging pads and charging devices are dense, cross-connection errors between the wireless charging pads and charging devices can occur within the same short-range wireless communication range. In this work, an effective cross-connect abatement technique using a received signal strength indicator (RSSI) signal and an in-band magnetic field signal modulated by a pulse with modulation (PWM)-like waveform is proposed to prevent cross-connection errors. The experimental results in dense LC wireless charging pad environments show that the proposed technique provides stable wireless charging services without cross-connection errors.
