“…Different solutions proposed with this type of configuration can be observed in [92], [93], [94], [95], where data is transmitted by means of a power amplitude variation, and in [67], [96], [97], [98] where power frequency variation is the chosen method.…”

“…Finally, it should be highlighted that although this technology requires the power signal to be modified to perform the data transmission, the initial stages of the communication, such as handshaking process, can be correctly carried out without initiating the power transmission. An example of the correct functioning of this process can be found in [92].…”

Wireless charging of Electric Vehicles (EVs) has become an important research topic in recent years. During the wireless charging process, wireless data exchange must take place between the EV and the charging station. Battery status, current and voltage of the charger or the EV identification may be required on the primary side in order for the system to operate properly. This data exchange can be carried out through commercial wireless communication solutions such as Bluetooth, 802.11 or ZigBee. However, these technologies introduce cybersecurity problems, high and variable transmission delays and possible connection losses during communication. To address these issues, numerous solutions have been proposed based on wireless data transmission through the wireless power transfer circuit. This paper gives a comprehensive review of the different issues that need to be considered for simultaneous wireless power and data transmission (SWPDT) for wireless EV charging applications. This context represents a challenge for SWPDT due to the power levels and the high probability of operating with notable misalignments or even with the EV on move. Specifically, a classification of SWPDT systems is described, and six different criteria to consider when designing a SWPDT system are analysed for EVs. The suitability of different system configurations is evaluated according to three representative use cases: (i) providing maximum efficiency, (ii) synchronisation for bidirectional wireless chargers and (iii) dynamic charging. We have also analysed the feasibility of using the Open Charge Point Protocol (OCPP) together with ISO 15118, which is the most popular communication protocol used in EV charging infrastructures,

“…Vehicle charging using WPT is unmatured at the moment, there are still weaknesses to be resolved such as low power transferring efficiency and alignment of power transmission pads [18][19][20]. Compared with electric vehicles using wired charging, the wireless charging methods do have potentials from the viewpoint of driver convenience.…”

This research task proposes a magnetic resonant coupling wireless power transfer (MRC-WPT) scheme for electric vehicles, which realizes secure data communication between the wireless charging station and the electric vehicle using binary phase shift-keying (BPSK) data transmission, thereby waving any radio frequency (RF) communication links. The secondary side is designed to accept power while transmits data back to the primary side simultaneously. The BPSK design ensures data transmission robustness to against disturbance interference. The data is encrypted by the user's biometric features for information security. The magnetic resonance performs better than that of the traditional magnetic induction in the power transmission efficiency against coil misalignments. With the Internet of Thing (IoT) architecture, the encrypted data can be stored and retrieved via the cloud server.
