Abstract This research proposes bidirectional power and data transfer which implements electric vehicle (EV) battery charge/discharging using magnetic resonance coupling wireless (MRC‐WPT) with inner communication by binary phase‐shift keying (BPSK) technology between the primary side secondary side. The MRC‐WPT‐BPSK can implement grid‐to‐vehicle, vehicle‐to‐grid, or vehicle‐to‐load (V2L) functions due to capability without additional modules such as Wi‐Fi, Bluetooth, ZigBee, so on. In...

Implementation of a multifunctional contactless bidirectional charging and discharging system with the aid giant magnetoresistance (GMR) effect for car parking guidance is proposed. Traditional Hall sensors can detect magnetic flux changes. However, if changes are not significant enough to induce detectable interference voltage, there will be error detection. To remedy, GMR sensor may tiny in field, which produce larger change resistance; this resistance less susceptible external noise...
