“…From ( 2), it can be confirmed that the phase difference between 𝑣 p and 𝑖 s is a constant 𝜋/2 rad. From this relationship, by synchronizing the secondary-side converter with 𝑖 s , it also synchronizes with the primary side (2) . Similarly, the phase difference between 𝑖 s and 𝑣 Lssc is a constant 𝜋/2 rad.…”

“…However, this method requires corrections to account for crosscoupling effects between the secondary side coils, which complicates the design. In literature (2), a current sensor is installed in the secondary side of the resonant network to synchronize the system operation by detecting the zero crossing point of the current. However, such current sensors with good frequency characteristics tend to be expensive.…”

This paper proposes a phase-synchronization method for double-sided LCC wireless power transfer systems with active rectifiers, achieved by using a current detector. The detector can be constructed inexpensively by simply adding a winding to the compensation inductor. Furthermore, the detector provides voltage step-down and isolation functions. Experimental results confirmed that the proposed method successfully synchronizes the primary and secondary systems across a wide range of coupling states for the transmission coils, with a coupling factor 𝑘 ranging from 0.05 to 0.3.

“…Although there are commercial communication platforms that could be used for the transmission of this parameter, the communication delay is variable due to the uncertain number of phases required for the transmission (initial setup, pairing, etc.). When using these platforms, the system is forced to incorporate complex synchronisation techniques as the ones described in [79]. SWPDT could avoid the need for synchronisation techniques as the control designer could set the sequence of the communication phases in such a way that the communication latency can be precisely estimated on the secondary side.…”

“…Figure 25 shows the curve defining the relation between the data rate (from 1 bps to 20 kbps) and the transmission time (from 8 seconds to 400 µs). As indicated in [79], for synchronisation, times longer than milliseconds should be avoided, therefore it is recommended that for the design of a SWPDT system for this application, the data rate should be at least 8 kbps. • Compensation system.…”

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,
